The health effects of Vitamin A in Endometriosis

Endometriosis growing somewhere else other than the endometrium also reacts to hormonal signals of the monthly menstrual cycle by building up tissue, breaking it, and eliminating it through the menstrual period. As we know, nutritional supplements play a very important role in treating endometriosis. In this article, we will discuss how vitamins help to treat endometriosis.
A. Vitamin A
I. Definition
Vitamin A is a bi-polar molecule formed by bonds between carbon and hydrogen. It is a fat soluble vitamin. This means it can not be stored in the liver but it can be converted from beta-carotene, a powerful antioxidant. Besides helping in treating endometriosis, it is also known to have strong effects in improving vision and enhancing bone growth.
II. The health effects
1. Vitamin A is a very powerful antioxidant that not only helps to strengthen the immune system, but also protects against the growth of endometriosis, according to the University of California, The combination of Simvastatin and Retinoic acid (RA), showed that Simvastatin potentiated an inhibitory effect of RA on growth of human endometrial stromal (HES) cells(1), probably through suppressing interleukin-6 production in human endometrial cells(5).

2. Vitamin A helps in regulating the gene expression by fighting against the forming of free radicals and protecting the body organs from abnormal growth of endometrial implants and adhesion, according to the Feinberg School of Medicine at Northwestern, endometriotic stromal cells, cause decreased expression of these genes of that leads to decreased retinol uptake and dominant FABP5-mediated prosurvival activity(2).

3. Vitamin A working together with other antioxidants as well as functioning of protein synthesis and fatty acid metabolism reduced oxidative stress which is a component of the inflammatory reaction associated with endometriosis(4), according to Université Catholique de Louvain(3).

4. Iron is necessary for production of red blood cells that carry oxygen in the blood stream for the body’s cells(7). Women who have endometriosis with heavy blood loss during menstruation normally have iron deficiency because of loss of iron which is far greater than what the body can produce leading to anemia(8) as S-ferritin levels were inversely correlated with the duration of menstrual bleeding. Intake of vitamin A and iron will increase the production of red blood cells far better than taking iron supplements alone(9).
Remember, overloading on zinc or iron is toxic to our body and may induce endometriosis(6). Please make sure to talk to your doctor for the correct amount.

1. Banana and constipation
Constipation is a condition of frequent and hard to pass in bowel movement. According to right diagnosis, approximately 30 percent of US population are experience of gastrointestinal complaint every year. chronic constipation (CC) study in adult Moscow population in a 1189 randomly selected subjects, showed statistical significant of 34.3% subjects affected by the disease, 16.5% had CC according to Rome III criteria. Female have significantly higher rate of 2 symptoms of constipation(1). Fructooligosaccharides, a chemical compound found abundantly in banana, in a study by University of Murcia, showed to increase fecal bolus and the frequency of depositions, with a dose of 4-15 g/day given to healthy subjects will reduce constipation(2). Unfortunately, its seeds may induce constipation,(3) especially when they are consume in empty stomach, according to 1SFE Medical Project, Luang Namtha(4).

2. Banana and bacterial activity
The immune system is the set of cells and their activity against antigens or infectious agents that comprises of the body’s defense system against diseases. The immune system does a great job of keeping people healthy and preventing infections. Beside foods and nutritional supplements, herbs also play a important role in helping the immune system defend against viruses and bacteria attacks.

According to the National Pingtung University of Science and Technology, Taiwan, hot water banana peel extract may be effective as bacteriostat, and immunostimulant and physiological regulator, through injection administration to enhance immunity, physiological responses, and resistance against L. garvieae in prawns study(1). The combination of saba (Banana)starch with L. plantarum CIF17AN2 showed a statistically significant in inhibition against Sal. Typhimurium SA2093 in the simulated colon model(2). The study of banana peel efficacy in biosurfactant-producing bacteria, showed the peel may be used to obtain crude biosurfactant fora broad spectrum of antimicrobial activity(3).

3. Banana and Diabetes
Diabetes is defined as a condition caused by insufficient insulin entering the bloodstream to regulate the glucose. It is either caused by cells in pancreas dying off or receptor sites clogged up by fat and cholesterol. In some cases, diabetes is also caused by allergic reactions of cells in the immune system.
According to the University College of Medical Sciences, India, Musa sapientum Linn (banana), has been used in India for the treatment of gastric ulcer, hypertension, diarrhea, dysentery, and diabetes. In rat study, the stem of lyophilized stem juice of M. sapientum Linn., showed to exhibits antidiabetic and antihyperlipidemic effects.(1). In support of the aboce, the Sri Jayachamarajendra College of Engineering study, suggested that ethanol extract of banana pseudostem (EE) exert an anti-diabetic effect by inhibition of α-glucosidases from the intestine, in turn suppressing the carbohydrate absorption into the bloodstream(2). According to the Central Food Technological Research Institute, banana (Musa sp. var. elakki bale) flower and pseudostem showed to induce symptoms of hyperglycemia, polyuria, polyphagia, polydipsia, urine sugar, and body weight in banana flower- and pseudostem-treated rats(3).

4. Banana and antihyperlipidemic effects
Cholesterol is needed for our body to build cell walls, make hormones and vitamin D, and create bile salts that help you digest fat. However too much of it can be dangerous because cholesterol cannot dissolve in your blood. The special particle called lipoprotein moves this waxy, soft substance from place to place. If you have too much low density lipoprotein LDL that is known as bad cholesterol, overtime cholesterol can build up in your arterial walls causing blockage and leading to heart attack and stroke.
The pulp of banana fruit (Musa sapientum L. var. Cavendishii) , including soluble and insoluble components of dietary fibre showed to exhibit anti hypocholesterolaemic effect with no affect the concentration of serum cholesterol(1). In support of the above, the University of Auckland study showed that resistant starch in Micronesian banana cultivars showed to have beneficial effects in disease prevention including modulation of glycaemic index diabetes, cholesterol lowering capability and weight management(2). Ethanol extract of mature green fruits of Musa AAA (Chenkadali) (bananas and plantains), according to Faculty of Veterinary and Animal Sciences, Mannuthy contained ntioxidant and hypolipidaemic properties and may be used for treating diabetes mellitus(3).

Gastric ulcer, a type of peptic ulcer is defined as a condition of a localized tissue erosion in the lining the stomach.
Extract of Musa sapientum fruit (MSE) exhibit antidiabetic and better ulcer healing effects ) in diabetic rat and could be more effective in diabetes with concurrent gastric ulcer, according to the Banaras Hindu University(1). The study of Methanolic extract of Musa sapientum var. Paradisiaca (MSE, 100 mg/kg), showed to exert its ulcer protective through its predominant effect on mucosal glycoprotein, cell proliferation, free radicals and antioxidant systems(2). In Peptic ulcer disease (PUD), encompassing gastric and duodenal ulcers, active compound of Musa sapientum, a monomeric flavonoid (leucocyanidin) showed to promote anti-ulcerogenic activity(3).

6. Banana and hypertension
Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. High blood pressure means raising pressure in your heart.If it stays high over time it can damage the body in many ways.
Blood pressure medications have undoubtedly prevented many deaths from heart disease in the past 30 years, but they have many side effects such as damaging the kidney
Corosolic acid (CRA), a constituent of banaba leaves, according to the Mukogawa Women’s University, showed to ameliorate hypertension, abnormal lipid metabolism, and oxidative stress as well as the inflammatory state in a 14 weeks rat study(1). In healthy volunteers study, banana showed no significant changes in heart rate and peak expiratory flow rate but only significant decrease in plasma ACE activity. Banana treatment decreased the rise of systolic blood pressure and diastolic blood pressure in healthy volunteers subjected to cold stress test without much effect on heart rate and peak expiratory flow rate(2)

7. Banana and diarrhea
Diarrhea is a condition of frequent bowel movements with three loose or liquid each day. prolong period of diarrhea may result in dehydration due to fluid loss.
Banana flakes, according to the 1Pennsylvania Hospital, can be used as a safe, cost-effective treatment for diarrhea in critically ill tube-fed patients. Banana flakes can be given concurrently with a workup for C. difficile colitis, thereby expediting treatment of diarrhea.(1). Green banana or its chemical compound pectin in the study of Bangladeshi children showed to benefit in management of persistent diarrhea in hospitalized children and may also be useful to treat children at home(2). In support to the above, the Hospital Universitario de Maracaibo, insisted that green plantain showed to be effective in dietary management of persistent diarrhea, in a prospective, in-hospital controlled trial, two different treatments were administered to a sample of 80 children of both sexes, with ages ranging from 1 to 28 months(3).

Chaste tree berry is a species of Vitex agnus-castus, genus Vitex, belonging to the family Lamiaceae, native to the Mediterranean region. It has been used in herbal medicine for thousands of year as anaphrodisiac herb and is considered as Queen herb in treating menstrual problems and discomforts by taking it in a prolonged period of time. There was report that reports chaste tree berry stems and leaves used by women as bedding “to cool the heat of lust” during the time of the Thesmophoria,

Chemical constituents
1. β-citronellol
2. Labdane-type diterpenoids,
3. Halimane-type diterpenoid,

9. Abietane-type diterpenoids

Health Benefits
1. Chaste tree berry and premenstrual syndrome (PMS)
Premenstrual syndrome effects over 70% to 90% of women in the US and less for women in Southeast Asia because of their difference in living style and social structure. It is defined as faulty function of the ovaries related to the women’s menstrual cycle, it effects a women’s physical and emotional state, and sometimes interferes with daily activities as a result of hormone fluctuation. The syndrome occurs one to two weeks before menstruation and then declines when the period starts.
A double-blind, randomized, placebo-controlled parallel trial was conducted over 16 weeks on menopause-related symptoms with combination of Hypericum perforatum (St. John’s wort) and Vitex agnus-castus (chaste tree/berry), showed a superior effect of the combination when compare to placebo in total PMS-like scores (p = 0.02), PMS-D (p = 0.006), and PMS-C clusters (p = 0.027). significant reductions in the anxiety (p = 0.003) and hydration (p = 0.002) clusters and suggested that the combination may be a potentially significant clinical application for this phytotherapeutic combination in PMS-like symptoms among perimenopausal women(1). The preliminary data of Technion-Israel Institute of Technology also support the efficacy of Chaste tree fruit (Vitex agnus) in the treatment of PMS(2). In a 1634 patients suffering from premenstrual syndrome (PMS), to test fpr the effects of Vitex on psychic and somatic complaints, on the four characteristic PMS symptom complexes depression, anxiety, craving, and hyperhydration (DACH), and on single groups of symptoms, indicated that Vitex treatment period of three menstrual cycles 93% of patients reported a decrease in the number of symptoms or even cessation of PMS complaints(3).

2. Chaste tree berry (Vitex agnus-castus) and leukaemia
Leukemia is defined as condition of abnormal increase of white blood cells produced by the bone marrow and/or the lymphatic system. Depending to the malignant granulocytes or lymphocytes, leukemia is classified into myelogenous or lymphoblastic leukemia.
Bone marrow is soft tissue inside the hollow center of major bone. including spine, pelvis, under arm, leg. etc.
Chaste tree berry may process an anti leukaemia effect. According to the Tokyo University of Pharmacy and Life Sciences, Chaste tree berry extract inhibited HL60 liver cancer cell line through Vitex induced a dose- and time-dependent decrease in cell viability associated with induction of apoptosis and G2/M cell cycle arrest in a a dose- and time-dependent manner(1). Also on leukemia cell lines, HL-60 and U-937, extract from the ripe fruit of Vitex agnus-castus (Vitex), inhibited both cell lines through its cytotoxicity activity in dose depend manner(2).

4. Chaste tree berry (Vitex agnus-castus) and Menopausal symptoms
Menopause is the defined as a condition in which a woman is in the transition stage of permanent cessation of the ovaries functions in egg production because of less production of estrogen and progesterone, signalling the end of the reproductive phrase a woman’s life. In menopause, menstruation has become irregular and slowly stop overtime, but in some women, menstrual flow comes to a sudden halt.

In a self-administered questionnaire, containing 15 questions, sent to all gynecologists in private practice in Germany to evaluate the complementary and alternative medicine (CAM) in the treatment of climacteric disorders, 98% of the returnees are experience with therapies of black cohosh (Cimicifuga racemosa), chaste tree (Vitex agnus castus) and St. John’s wort(1). According to the 1Royal Melbourne Institute of Technology (RMIT) University, Bundoora, although evidence from rigorous randomized controlled trials is lacking for the individual herb emerging pharmacological evidence supports a role for V. agnus-castus in the alleviation of menopausal symptoms(2). Dr. Chopin Lucks B. in the trial of two essential oils (derived separately from leaf and fruit) of Vitex agnus castus indicated that both essential oil shows a strong symptomatic relief of common menopausal symptoms(3).
Unfortunately, according to the University Hospital Hamburg-Eppendorf, Agnus castus showed no significant difference in the treatment of climacteric complaints(4) with a combination of Hypericum perforatum (St. John’s wort) and Vitex agnus-castus (Chaste tree/berry) also showed the same(5).

Dehydroascorbic acid (DHA)(*) 12% concentration regained the youthfulness of Forearm between the Wrist and Elbow in stimulated reproduction of Collagen against Sagging skin

Kyle J. Norton

I have truly believed that scientists have found a natural ingredient for define-aging, but it was shelved as it offers no commercial value. If one is published with effectiveness more superior than the currently sold products, it may be a death spell to many companies which rely totally in selling cosmetic products.
Anti-aging and maintaining our youthful appearance has been researched throughout human civilization. Today, these researchers have become more aggressive as finding a workable agent may produce billions of dollars of profits to the found company. According to statistics, Global Anti-Aging Products Market will reach $291.9 Billion by 2015.

Dehydroascorbic acid (DHA)(*) 12% concentration may be a potent solution in regained the youthfulness of forearm between the wrist and elbow in stimulated reproduction of collagen against Skin sagging due to aging progression.

Abstract
Introduction
Skin aging is one of the most visible ageing processes that occur constantly in our skin organ. Many ingredients from synthetic and natural sources have been proven in studies to have certain effects on skin aging. In our previous study, Dehydroascorbic acid (DHA) at 4% showed a significant improvement in smoothing of the skin, skin elasticity, firming, disappearance of black and white heads, liver spots, pigmentation, and healing acne and acne scars. In this study, Dehydroascorbic acid (DHA) at 12% is tested for its effectiveness in stimulated reproduction of collagen in the forearm between the wrist and elbow.

Method of Experimentation
10 Patients at age 59 -60 (5 females and 5 males; 5 Caucasians, 3 Asians and 2 Africans) were recruited to test for aging process due to loss of collagen causes of skin sagging in the forearm (left or right) between the wrist and elbow.

Patients must also agree during the study that they will not to use any other topical products (such as including moisturizers, sunscreens, and fragrances, make-up and any facial procedures such as peels, facials, microdermabrasion, and injection of botulinum toxin type A or dermal fillers) but the testing solution. The study also examines the patient with any cosmetic surgery and/or medication use of which may interfere with the study, as well as history of facial skin diseases. All patients are also required to sign an informed consent. Solutions of Dehydroascorbic acid (DHA)(*)were remixed every 3 days in order to maintain their refreshness and concentration levels.
Patients were instructed to stir the solution well with wooden chopstick or ice cream stick and wear glove when apply the solution to prevent oxidation causes of brownness in the palm and figure nails due to high concentration of the solution, as well as to cover the applied areas before going out to extreme sunlight.
Patients were also instructed to apply the provided solution on their forearm between the wrist and elbow for a duration of 12 weeks. Forearm up to the wrist examinations were conducted and recorded every 4 weeks.

Results
All patients completed the trial. Topical administration of Dehydroascorbic acid (DHA)(*) 12% showed to stimulate the reproduction of collagen in enhancing the youthfulness of the applied area up to 95% in 4 patients

Conclusion
Treatment of concentrations of Dehydroascorbic acid (DHA)(*) at 12 % exhibited a significant efficacy in rejuvenation of the youthfulness of forearm between the wrist and elbow through reproduction of collagen skin smoothing, elasticity, firming, probably through anti-inflammatory and skin absorption pathways, in doses, skin aging progression and durative depending manner. It may be used to rejuvenate the skin in other parts of the body. Since the experimental group is small in nature, further studies with a larger sample size are necessary to improve the ingredient’s validation.

Introduction
Skin aging is one of the most visible aging processes that occur constantly in our skin. According to the Clinical Centre of Nis, certain plant extracts may have the ability to scavenge free radicals to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin, and affect skin elasticity and tightness (a). Another study suggested that free radicals induced domino effects in production of reactive oxygen species and can react with DNA, proteins, and fatty acids causing oxidative damage and impairment of the antioxidant system, leading to injuries, damage of the regulation pathways of skin causing wrinkles, roughness, appearance of fine lines, lack of elasticity, and de-pigmentation or hyperpigmentation marks (b).
Walking through the drug and commercial cosmetic stores, one can see hundreds of anti-aging creams and products displayed. Many of them have also gone through certain studies for its efficacy with advertisement through media and celebrities. In fact, according to statistics, Global Anti-Aging Products Market will be worth $291.9 Billion by 2015.
Searching through the key word of Dehydroascorbic Acid (Oxidized Vitamin C, DHAA) and skin has yielded no related studies or clinical trials. It may be the result of the solution having no commercial value as it can be made by any cosmetic purchaser, or the studies indicate that L-ascorbic acid must be formulated at pH levels less than 3.5 to enter the skin with maximal concentration of 20% for optimal percutaneous absorption. But according to Dr. Douglas Q. Kitt, Dehydroascorbic Acid (DHAA) permeates stratum corneum at a rate up to 12 times faster than AA. This supports the concept that lower concentrations of DHAA in topical preparations can enhance skin vitamin C levels with less potential side effects (c).
Ingredient 1: Dehydroascorbic Acid (DHA) (vitamin C supplement oxidized form)
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin found in fresh fruits, berries and green vegetables. It is best known for its free radical scavenging activity and regenerating oxidized vitamin E for immune system support. In skin aging, the vitamin may improve solar radiation protection and epidermal aging (1) through production of collagen due to its antioxidant activity (2)(3).
Epidemiological studies linking vitamin C in prevention of skin damage and aging have produced some certain results (3a)(3b)(3c), but the large sample size and multi-centred studies are necessary to validate its effectiveness. Vitamin C oxidized form or dehydroascorbic acid (DHA) processed antiviral and virucidal effects (23) showed to prevent H2O2-induced cell death by increasing the GSH levels mediated by the GPx and GR activities and PPP (17), and regulated neuronal energy metabolism, through facilitating the utilization of glucose via the PPP for antioxidant purposes (18) by increasing antioxidant potential in the central nervous system (19). Dehydroascorbic acid (DHA) may be a potential anti-cancer agent to treat aggressive cancers (20)(21). Dr. Toohey at the Cytoregulation Research said “rapidly-dividing tumour cells make unusually large amounts of homocysteine thiolactone and that administered dehydroascorbic acid enters the cells and converts the thiolactone to mercaptopropionaldehyde which kills the cancer cells” (22).
1. Plasma levels of vitamin C L-ascorbic acid is known for its effects on skin-whitening and against the anti-oxidation causes of skin aging. During the aging process, levels of vitamin C was found to slowly deplete according to the Tokyo Metropolitan Institute of Gerontology in the measurement of plasma and urine of C57BL/6 male mice during 3 to 30 months of aging(4). Therefore, restoration of physiological levels of vitamin C inside the cells might improve the lysosomal degradation (protection of cell from the degradative enzymes through protection of the cytosol) in the outflow pathway cells and prevent the pathogenesis of glaucomadegrade proteins(5).
Unfortunately, some researchers suggested that higher levels of circulating vitamin C may not provide protection against incident radiographic knee OA, and be associated with an increased risk of knee OA(6) and the 1Panorama Research Institute and Regenerative Sciences Institute, insisted “careful attention to individual and family medical history and personal genomic data may prove essential to make wise dietary and supplement choices to be combined with exercise”(7).

2. The effects
According to the Minghsin University of Science and Technology, in doses of a dependent manner, the concentration of L-ascorbic acid induced absorption of the collagen solution in exhibition of smoothing wrinkles and clear up spots(8). Ascorbic acid (AA) is essential in stimulating collagen gene expression. In type 1 and type 4 collagen and SVCT2, the vitamin was found to enhance the expression of type 1 and type 4 collagens and SVCT2 mRNA in cultured human skin fibroblasts at 100 μM AA placed every 24h for 5 days to prevent depletion(9). The Chiang Mai University study also supported the effects of ascorbic acid in the anti-aging process through exhibition pro and active MMP-2 inhibitory(10). Other studies suggested the combined vitamins, including vitamin C in a single formulation had a slightly lower degradation rate and more stable formulations as compared to different preparations containing only one of the vitamins(11)(12). Amazingly, in vivo, application of vitamin C showed a significant reduction of oxidative stress in the skin, an improvement of the epidermal-dermal microstructure and a reduction of fine lines and wrinkles in aged skin within a relatively short period of time of product application(13). The Bruce and Associates study also insisted the effectiveness of vitamin C application over a 12 week period as the vitamin enhanced the overall intensity of pigmentation, fine lines and wrinkles, tactile roughness, and laxity with a 100% satisfaction of overall appearance of the tested subjects’ skin(14).
1. Skin roughness and Scaliness
Skin roughness due to aging is a result of dead skin cells shedding more slowly, and building up in the upper layer of skin causing skin complexion to become rough and dull. According to the University of California at San Francisco, they are the result of aging and anatomic site of which demonstrated a significant influence on skin roughness and scaliness(25). Another study suggested that frictional properties of skin are dependent on more than water content or non-apparent sweating and the role of sebum secretion may be one possible factor(26), or it may be result of depletion of surface lipid content(27).
2. Wrinkles
Wrinkles are also associated with aging, hormonal status, smoking, and intercurrent disease according to the study by the University of California-San Francisco(28). Some researchers suggested that vitamin C may play an important role in collagen production due to its antioxidant properties(28). Another study indicated a positive anti-wrinkle effect through consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E, and fish oil(29).
3. Skin elasticity and firming
Skin sagging is a result of a loss of collagen and elastin of the skin due to aging in combination with the dreaded pull of gravity. The study of a novel dietary supplement (Imedeen Prime Renewal) including soy extract, fish protein polysaccharides, extracts from white tea, grape seed and tomato, vitamins C and E as well as zinc and chamomile extract, showed to inhibit forehead, periocular and perioral wrinkles, mottled pigmentation, laxity, sagging, under eye dark circles, and overall appearance. After 6 months treatment, it was suggested that the formula may provide improved condition, structure and firmness of the skin in post-menopausal women(30). Other studies insisted that since vitamin C (Vit. C) in the form of L-ascorbic acid (Asc) can accelerate wound healing(33)(32) and protect fatty tissues from oxidation damage(33), it may play an integral role in collagen synthesis of reducing wrinkles and skin sagging(34)(35)
5. Liver and aging spots
Liver spot is a condition of brown or black spots appearing on the surface of the skin due to aging and exposure to ultraviolet radiation from the sun. According to skin care guides, high concentration of Vitamin C may improve the skin and lighten the spots(36). Other articles insisted that liver spots may be the result of a deficiency of vitamin C(37). According to the Duke University Medical Center, the application of topical solutions containing vitamins C and E provided protection for human skin against damage caused by ultraviolet radiation(38)(39)(40)(41).
6. Pigmentation
Skin pigmentation disorder is a result of damage most likely caused by UV sunlight, or unhealthy cells due to aging affecting the production of melanin. Vitamin C topical and by iontophoresis are found effectively in aiding post-laser hyperpigmentation or short and long term treatment (42) for melism (43). In an experiment where 29 females with melisma enrolled for iontophoresis, a vitamin C solution was applied to one side of the face, while distilled water was applied to the other side as a control, treatment with colorimeter site showed a significant decrease in the luminance value, (a photometric measure of the luminous intensity per unit area of light) compared to that of the control site (44).
8. Acne and Acne scars
According to Dr. GEORGE E. MORRIS, M.D., in a study of 60 patients with acne being given 8 oz of citrus juice twice daily and vitamin C in 3 gm a day, after 4 months 43 showed improvement, 10 failed to show improvement and 7 did not return for follow up(45). Some articles showed that vitamin C may be effective in the reduction of the formation of acne scars through it’s anti-inflammatory and free radical scavenger activities(46), but no study has been found through searching on PubMed.

9. Back and White heads
Black and white heads are the result of a skin pore becoming clogged with sebum from the body’s natural oil and becoming black heads if oxidized. No study has been found specifically for the key word vitamin C and back and white heads on PubMed.

10. Fine Lines
No study and been found.

Method
A total of 10p atients were recruited with ages ranging from 59 – 60 (5 Caucasians, 3 Asians and 2 Africans, and 5 females and 5 males) to test for the effectiveness in the difference of concentrations of Dehydroascorbic acid (DHA) at 12% ( 24000mg diluted into 100 mL of hot water which is let cool before refrigerating).

Patients are eligible to enter this study
Selection was based on those who had moderate to severe forearm wrinkles. Patients must also agree during the study that they will not to use any other topical products but the testing solution, such as moisturizers, sunscreens, fragrances, make-up, and any facial procedures such as peels, facials, microdermabrasion, and injection of botulinum toxin type A or dermal fillers. The study also examines the patient with any cosmetic surgery and medication use which may interfere with the study, as well as history of facial skin diseases. All patients are also required to sign an informed consent.
Patients were instructed to stir the solution well with wooden chopstick or ice cream stick and wear glove when apply the solution to prevent oxidation causes of brownness in the palm and figure nails due to high concentration of the solution, as well as to cover the applied areas before going out to extreme sunlight.
Patients were also instructed to apply the provided solution on their forearm up to the wrist for a duration of 12 weeks. Facial skin examinations were conducted and recorded every 4 weeks.

As the data indicates, patient satisfaction with the solution and the progression of skin sagging reduction.

Tolerability
Through over 12 weeks of application with the designed solution, no adverse effect has been reported in the group.

Discussion
Dehydroascorbic acid (DHA)(*) showed the most efficacy in enhanced smoothness, firmness, and elasticity of the skin through stimulation the production of collagen on forearm between the wrist and elbow, probably through its antioxidant activities via inflammatory pathways, and skin absorption property. It may be used in other parts of the body including facial skin.
The efficacy of the solutions indicated a logical thinking through maintaining healthy skin by preventing the loss of collagen due to aging is the most effective way to slow down the aging progression. Dehydroascorbic acid (DHA)(*) at 12% concentration may provide us with more insight with this astonished result, but further study is necessary to rule out any adverse effect and improve its validation, due to small sample size.

Please make sure that you discuss the use of any topical solution in the study with your doctor or related field specialist before applying. Please Donate for funding the larger sample size study to improve the validation of this discovery.

Phytochemical Polysulfides

Kyle J. Norton

Polysulfides are phytochemicals in a class of chemical compounds containing chains of sulfur atoms, belonging to the group of Organosulfides found abundantly in ioxidized product, including beer, wine, whiskey, garlic oil, etc.
1. Phytochemical Polysulfides and colon cancer
Bowel cancer also known as colorectal cancer, is defined as a condition of the abnormal proliferation of cells in the colon, rectum, or vermiform appendix. Bowl is divided in 2 parts, the first part of the bowel, the small bowl, is involved with the digestion and absorption of food. The 2nd part, the large bowel which consist the the colon and rectum, is involved in absorption of water from the small bowel contents and broken down of certain materials in the feces into substances of which some of them to be re absorbed and reused by the body. Bowel cancer is relatively very common and slowly growing and progress cancer and in predictable way.
Bowel cancer is the third most commonly diagnosed cancer in developed countries, including U>S and Canada.
According to the study of the University of the Saarland, coumarin polysulfides showed to inhibit cell growth and induce apoptosis in HCT116 colon cancer cells, through regulated the phosphatase activity of the cell cycle regulating cdc25(Cell division cycle 25, family of dual-specificity phosphatases) family members(1). Diallylsulfides, another family member of Garlic-derived organo sulphur compounds, also inhibited HCT116 human colon cancer cells, through reduced cell viability, cell cycle arrest and apoptosis(2) and colo 205 human colon cancer cells through affected resistant gene expression(3)

2. . Phytochemical Polysulfides and breast cancer
Breast cancer (malignant breast neoplasm) is a cancer started in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) that supply the ducts with milk. there is also rare cases that breast cancer starts in other areas of the breast. In 2010, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.
Eating garlic daily and regularly is associated to reduced risk of cancer due to its properties in stimulated cells arrest at G2/M phase, the cells with a sub-G1 DNA content, and the cells with caspase-3 activity(1). In sensitive (MCF-7) and resistant (Vcr-R) human breast carcinoma cells , Diallyl- and dipropyltetrasulfides showed to inhibit growth of both cancer cell lines, through cell cycle arrest associated to antiproliferative effect(2). The Alexandria University study also supported the role of diallyl trisulfide in inhibition of MCF-7 breast cancer but throught enhanced the expression levels of FAS and cyclin D1, but in contrast, downregulated the expression levels of Akt and Bcl-2(3).

3. Polysulfides and skin cancer
Skin cancer is a medical condition of uncontrolled growth of abnormal skin cells and often detected at an early stage.
In skin cancer progression, diallyl trisulfide (DATS) is more potent than mono- and disulfides against skin cancer, through inhibited cell growth of human melanoma A375 cells and basal cell carcinoma (BCC) cells by increasing the levels of intracellular reactive oxygen species (ROS) and DNA damage and by inducing G2/M arrest, endoplasmic reticulum (ER) stress, and mitochondria-mediated apoptosis(1). The study by the National Taiwan University, also showed that Diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS), extracted from crushed garlic, inhibited skin cancer cell growth through involved in G(2)/M arrest and apoptosis via activation of p53 pathway in response to the oxidative DNA damage(2). The Chung Shan Medical University Hospital, study also insisted that DAS protect against ultraviolet B (UVB)-induced skin tumor formation through anti photocarcinogenesis effect accompanied by the down-regulation of cell-proliferative controls, involving thymine dimer, PCNA, apoptosis, transcription factors NF-κB, and of inflammatory responses involving COX-2, PGE2, and NO, and up-regulation of p53, p21/Cip1 to prevent DNA damage and facilitate DNA repair in hairless mice(3).

4. Phytochemical Polysulfides and cardiovascular diseases
There are many causes of heart diseases. Most of heart diseases are caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. Beside cancer, heart disease kills more than 2,000 Americans everyday. Approximately 60 million Americans have heart disease.
Epidemiologic studies link intake of garlic in association to reduce risk as well as progression of cardiovascular disease(1).
According to the Institute of Preventive and Clinical Medicine, polysulfides from garlic are converted into hydrogen sulfide which has the unique property for relaxing vascular smooth muscle, inducing vasodilation of blood vessels, and significant reducing blood pressure(2), probably through its anti-apoptotic, anti-inflammatory and antioxidant effects(3). The 1Semmelweis University Institute of Human Physiology and Clinical Experimental Research, suggested that H2S as a novel gasotransmitter in the central nervous and cardiovascular systems, similarly to nitric oxide (NO) and carbon monoxide (CO), may be of value in cytoprotection during the evolution of myocardial infarction(4).

The Science of Soy – The East Viewpoints: Part A5 – Soy and Menopause Symptoms in Japanese

By Kyle J. Norton

Soy foods, including tofu have been in traditional Chinese diet over thousands of year, according to Chinese literature. The reduced risk of chronic disease, including metabolic syndrome such as cardiovascular diseases, obesity and diabetes and lesser menopause symptoms in advanced age, may be aided by eating a lot of soy food accompanied with large portion of vegetables and fruits. Indeed, according to the study, only 10% of women in the East are experience symptoms of menopause in advanced age compared to over 70% of their Western counterparts.
According to Dr. Mark Messina, Ph.D., Soy foods contributed from 6.5%8 to 12.8%7 of total protein intake in older adult in Japan.(b)

The approval of cardiovascular benefit of soy by FDA in 1999 accompanied with the discovery of health benefits in clinical studies over past decade, prompted the promotion and advertisement of soy’s health benefits in every aspect in Western society. Evidences could be seen by walking through the supermarkets and drug stores. Soy supplements and products such as tofu, soy milk, soy-based infant formula, and meatless “texturized vegetable protein” burgers were widely available. According to the United Soybean Board’s 2004–2005, 25% of Americans consume soy foods or beverages at least once per week, and 74% view soy products as healthy.

Today, the promotion of soy are no longer existed, it may be results of discovery of adverse effect in single ingredient and animal studies, as intake of soy is associated to induce risk certain mammary cancers and infertility. The publication of the result have drawn many criticisms. According to Thomas Badger, director and senior investigator at the Arkansas Children’s Nutrition Center in Little Rock, these effects are seen only under certain experimental conditions that are not likely to occur in humans—and therein lies the crux of the debate(a). Equol (4′,7-isoflavandiol), an isoflavandiol metabolized from daidzein may be the causes, as 90% of Eastern population are equol producers but only 30% in the West.
The explanation of the positive effect of soy isoflavones in reduced risk of mammary cancers by University of Goettingen may be interesting, as researchers said” Most importantly, there is dispute as to whether isoflavones derived from soy or red clover have negative, positive or any effect at all on the mammary gland or endometrium. It is beyond any doubt that soy products may have cancer preventing properties in a variety of organs including the mammary gland. However, these properties may only be exerted if the developing organ was under the influence of isoflavones during childhood and puberty.

Soybean is the genus Glycine, belonging to the family Fabaceae, one of the legumes that contains twice as much protein per acre as any other major vegetable or grain crop, native to Southeast Asia. Now, it is grown worldwide with suitable climate for commercial profits.

I. Soy in Eastern population
A. The Japanese population
Japan, an island nation in the Pacific Ocean, lies to the east of the Sea of Japan, China, North Korea, South Korea and Russia, stretching from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south(1c). According to Moriyama, Japanese women and men live longer and healthier than everyone else on Earth, it may be result of healthier Japanese diet and lifestyle. According to the World Health Organization, the Japanese have an average of 75 years healthy living with disability-free, it may be due to average soy intake 10 to 70 times higher than in Western people(1a)(1b).

A5. Soy and menopause symptom in Japan
Menopause is defined as a condition in which women have not had a menstrual period in a minimum of 12 months period as a result of the inactive ovaries, assuming the women are not pregnant and experience the ease of visible symptoms of menopause such as hot flashes and night sweats but not the invisible effects of menopause. During post menopause, any bleeding or spotting should be reported to your doctor immediately, it may be caused by tumors rarely but it is possible. Symptoms may include Bleeding or spotting, Vagina itching and dryness, Hot flash, Bone pain and fracture, Bladder infection, Skin wrinkle, Hypertension, Bone density loss, etc.

Eppidemiological studies, linking soy effect on menopause symptoms have been inconclusive(1)(2)(3)(4). In japanese women, phytochemicals in soy found effectively in reduced vasomotor symptoms of menopause. In a supplement containing equol on the menopausal symptoms of Japanese, researchers at the Tokyo Medical and Dental University, showed that The equol-ingesting grou, noy only significantly reduced severity and frequency of hot flashes as, the severity of neck or shoulder but also exhibit trends of improvement in sweating and irritability and a significant improvement in the somatic category symptoms(5). Administration of 10-mg natural S-(-)equol supplement consumed daily for 12 weeks also indicated an reduction of hot flushes and neck or shoulder muscle stiffness, in postmenopausal Japanese women(6). And fermented soy products hhave been also showed to alleviate the severity of hot flushes(14).
Some researchers suggested that the effectiveness of soy isoflavone in relieved symptoms of menopause may link to equol-producing status. In a 1-year double-blind, randomized trial in comparison of the effects of isoflavone (75 mg of isoflavone conjugates/day) with those of placebo on bone mineral density, fat mass, and serum isoflavone concentrations in early postmenopausal equol-producer phenotype.Japanese women, found that isoflavones exhibited the preventive effects of isoflavones on bone loss and fat accumulation in early postmenopausal women depend on an individual’s equol-producing capacity(7) and S-equol supplement improved mood-related symptoms in perimenopausal/postmenopausal even in equol nonproducers in Japan women, in total of 127 participants completed the trial(8).

Soy isoflavone extracts on testing on lumbar spine or hip BMD in menopausal women of controlled trials published in English, Japanese, or Chinese, showed a result of varying effects of isoflavones on spine BMD across trials associated with study characteristics of intervention duration (6 vs. 12 months), region of participant (Asian vs. Western), and basal BMD (normal bone mass vs. osteopenia or osteoporosis)(9). In ciompared the symptom of hot flash and chilliness in menopause women, Dr. Melby MK. suggested that Japanese women are experience important vasomotor symptom than hot flushes and sweats, it may be result of dietary high in soy(10).

In Osteoporosis, menaquinone-7, the major chemical compound found Japanese fermented soybeans, showed to prevent postmenopausal bone loss(11) and promotion of bone formation(13)(15) as well eleviating early postmenopausal women, such as in palpitation and backaches(15). Other study also suggested that intake of supplementation of isoflavones (ISO) regulary associated to risk reduction of osteoporosis in middle-aged Japanese menopausal Japanese women(12).

In fact, according to the study of cross-sectional relationships of dietary and other lifestyle variables to menopause by the Gifu University School of Medicine, such as smoking, calcium and soy product intakes, intakes of fat, cholesterol, and coffee were significantly associated with the onset menopause in Japanese women(16).

Taken altogether, High soy food intakes are associated to reduce symptoms of menopause in Japanese women, chilliness. In take of supplement containing equol are effective in symptom reduction even in non equol producers in these population as well. According to the Royal Hospital for Women, highest soy consumption in Japan lowered the rates of diseases, such as breast, endometrial, colon and prostatic cancers atherosclerotic, etc. but induced extremely high urinary levels of phytoestrogen metabolites may be a result of isoflavones in exhibited bioactivity when intake of high concentrations.(17)

Phytochemical therapy – Phytochemicals Dithiolthiones (isothiocyanates)

Dithiolthiones are phytochemicals in the class of Organosulfides, found abundantly in cruciferous vegetables, garden sorrel, horseradish, etc.

The study of the hepatoprotective drug anisyldithiolthione was showed to be effective in acting as hepoprotective agent in inhibited lipid peroxidation induced in rat liver microsomes either chemically by FeSO4 and reducing agents (cysteine or ascorbate) or enzymatically, probably through the presence of its dithiolthione function(1) Other medication such as Anethol dithiolthione (ADT), usually prescribed as a choleretic drug, also exhibited an hepatoprotective potency at doses as low as 10 mg/kg relative to serum aminotransferase activities and hepatic glutathione related enzyme system in in Swiss female mice(2)

2. Isothiocyanates and cancers
Cancer is a class of diseases in which a group of cells growing and multiplying disordered and uncontrollable way in our body, have become progressively worse and damaged other healthy tissues, sometimes spreads to other organs in the body via lymph or blood and results may be in death.
In a case-control study conducted in urban Shanghai. The cases (from December 2006 to December 2008, ITC consumption from cruciferous vegetables intake showed a positive effect in reduce risk of pancreatic cancer after adjusting for possible confounding factors such as age, sex, history of diabetes and pancreatitis(1). Thiazolo, the synthesis of a novel class of quinazoline, produced by the reaction of 4,6-dichloro-5-aminopyrimidine with isothiocyanates in presence of 20 mol% KF/alumina, showed to exhibit antiproliferative activity in lung (NCI-H322 and A549), epidermal (A431) and glioblastoma (T98G), HL-60 cell lines at 20 μM. The effect of compound 4a on mitochondrial potential loss in HL-60 cells probably through cleavage of PARP-1 and procaspase-3 inhibition(2).
The study by Campus Morro do Cruzeiro suggested that the phytochemical inhibited the cell viability of human cervical cancer cells, human pancreatic cancer cells, human hepatocellular carcinoma cells, human ovarian cancer cells, and have antiinflammatory properties in the treatment of human T-cell leukemia cells(3).

3. Isothiocyanates as Antioxidants
Free radicals are atoms, molecules, or ions with unpaired electrons through chemical bonds with other atoms or molecules during a chemical reaction. They may have positive, negative or zero charge. The unpaired electrons cause radicals to be highly chemically reactive in the human body, leading to aging and cancers.
In Fuchs endothelial corneal dystrophy (FECD), an oxidative stress disorder, treatment with Sulforaphane, a molecule within the isothiocyanate group, decreased CEC apoptosis by 55% in unstressed group and by 43% in tBHP-treated specimens, through inhibition of oxidative stress(1).
The Universidade Federal de Ouro Preto study also indicated the similar result of sulforaphane in improvement of antioxidant status in the testing of number of cancer cell lines(2). Other study suggested that isothiocyanates (ITCs), found abundantly in cruciferous vegetables, may be effective as a cancer chemopreventive agent through modulation of phase II detoxifying/antioxidant enzyme activities(3).

4. Isothiocyanates and heart diseases
Beside cancer, heart disease kills more than 2,000 Americans everyday. Approximately 60 million Americans have heart disease.
There are many causes of heart diseases. Most of heart diseases are caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat.
In human immunodeficiency virus (HIV) patients, showed to improve AIDS-related heart dysfunction through inhibition of apoptosis by decreasing iNOS and Bax expression through suppression of NF-κB.(1). In ischemic injury of hearts patients, showed to inhibit reactive oxygen species mediators in exerting a toxic effect during ischemia-reperfusion through mitochondrial K(ATP) channels and antioxidant pathway(2). On ischaemia-reperfusion-induced cardiac injury. steamed broccoli showed a superior cardioprotective properties over cooked broccoli, probably through through the redox signalling of sulphoraphane(3). the phytochemical also found to trduce risk of vascular disease due to aging by inhibiting oxidative stress (4).

5. Isothiocyanates and neuroprotective effect
Sulforaphane, a naturally organosulfur compound found in broccoli, showed to exert its neuroprotective effects through significantly attenuated the scopolamine-induced memory impairment and improved cholinergic system reactivity, as indicated by an increased ACh level, decreased AChE activity, and increased choline acetyltransferase (ChAT) expression in the hippocampus and frontal cortex(1). in a variety of acute and chronic neurodegenerative diseases, phytochemicals, isothiocyanate sulforaphane, derived from the hydrolysis of the glucosinolate glucoraphanin mainly present in Brassica vegetables, demonstrated its neuroprotective effects in several in vitro and in vivo studies, may be mainly ascribed to its peculiar ability to activate the Nrf2/ARE pathway(2). In dopaminergic neurotoxicity in mice induced by 6-hydroxydopamine (6-OHDA), the phytochemical showed the neuroprotective effect through its ability to enhance glutathione levels and its dependent enzymes (glutathione-S-transferase and glutathione reductase) and to modulate neuronal survival pathways(3).

6. Sulforaphane and Obesity
Obesity is defined as a medical condition of excess body fat has accumulated overtime, while overweight is a condition of excess body weight relatively to the height. According to the Body Mass Index(BMI), a BMI between 25 to 29.9 is considered over weight, while a BMI of over 30 is an indication of obesity. According to the statistic, 68% of American population are either overweight or obese.
Taking foods containing sulforaphane may be effective in managing weight loss for obese patients accompanied with change of lifestyle with more vegetables and fruits into diet. Sulforaphane, a molecule within the isothiocyanate group, according to Chungbuk National University, showed to prevent high-fat diet (HFD)-induced obesity in C57BL/6N mice. through inhibiting adipogenesis( the cells differentiation for a vital role in energy homeostasis and process the largest energy reserve in the body of animals). via down-regulation of PPARγ(regulation of metabolism) and C/EBPα (inflammatory process) and by suppressing lipogenesis( protein as an intermediate stage in metabolism of simple sugars) through activation of the AMPK(in cellular energy homeostasis) pathway(1). Chronic oral administration of sulforaphane, on obesity and insulin resistance induced by a highly palatable (HP) diet in male Wistar rats, at the specific dose was able to accentuate glucose intolerance and may affect GLUT3 expression involed neuronal glucose transport in the cerebral cortex and hypothalamus(2). The Chonbuk National University also suggested that Sulforaphane suppressed AMPK phosphorylation(cellular energy homeostasis) at Thr-172 in a dose-dependent manner(3).

7. Sulforaphane and Lung diseases
Lung diseases is defined as a condition, affecting the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of breathing.
Sulforaphane may be used as a preventive chemical constituent of pulmonary damage for patient who exposure to arsenic. According to China Medical University, arsenic-containing dust resulted in ; all of which were blocked by sulforaphane (SF) blocked pathological alterations, oxidative DNA damage, and mild apoptotic cell death in the lung caused by 2 weeks of exposure to arsenic through activation of Nrf2(master regulator of the total antioxidant system)(1). In wildtype neonatal mice exposed to hyperoxia. SF also found to activated Nrf2 activation through induced expression of anti-oxidant genes,(2). In the lungs of the arrhythmic Clock(Δ19) mice, SF also activated it anti ovidative damage effect through activation of NRF2/glutathione defense pathway in combating oxidative/fibrotic lung damage(3).

8. Sulforaphane and Liver disease
Liver disease in most cases are linked to alcohol or drugs. In fact, it can be caused by a variety of factors and affecting everyone from infants to older adults.
In CYP2E1-dependent binge alcohol-induced liver steatosis, oral treatment of sulforphane sulforaphane showed to activated Nrf2, increased levels of the Nrf2 target heme oxygenase-1 and subsequently lowered oxidant stress as shown by the decline in lipid peroxidation and 3-nitrotyrosine protein adducts and an increase in GSH levels(1). In the comparison of the effectiveness of Sulforaphane and glucoraphanin in modulating carcinogen-metabolising enzymes in Hep G2 cells, Dr Abdull Razis AF1, and Noor NM found that sulforphane is superior to glucoraphanin in modulators of various phase I and phase II enzymes involved in carcinogen-metabolising enzyme systems in vitro(2). The University of Rhode Island, Kingston study also insisted that SF activate Nrf2 activation in inhibited lipid accumulation in white adipose tissue, suppressed adipogenesis, induced insulin resistance and glucose intolerance, and increased hepatic steatosis in Lep(ob/ob) mice(3)..

9. Sulforaphane and Breast cancer
Breast cancer (malignant breast neoplasm) is a cancer that starts in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) that supply the ducts with milk. there is also rare cases that breast cancer starts in other areas of the breast. In 2010, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.
The University of Michigan, also insisted that ingestion of sulforaphane at a dose of 50 mg/kg for 2 weeks inhibited breast cancer stem cells(1). According to Manipal University, Sulforaphane inhibited growth of human breast cancer cell line MCF-7 cells, through induces apoptosis and anti-inflammatory effects on MCF-7 cells via downregulation of Bcl-2 (anti-apoptotic protein) and COX-2 (inlvoved inflammatory process) respectively(2). Also in testing of MCF-7 breast cancer cells, researchers at the The Catholic University of Korea, showed that sulforaphane induced the inhibition of 12-O-tetradecanoyl phorbol-13-acetate (TPA)-induced MMP-9 expression(involved in keratinocyte migration and granulation tissue remodeling during wound healing) and cell invasion by via the suppression of the NF-κB (nvolved in cellular responses)pathway in MCF-7 cells(3).

10. Sulforaphane and Prostate cancer
Prostate cancer is defined as a condition in which the cells of prostate has become cancerous, causing abnormal cell growth which spread to the distant parts of the body. Most prostate cancers are slow growing and enlarged prostate and prostate cancer may be detected during the Physical (rectum) exams.
Oral administration of d,l-sulforaphane (SFN) can decrease the incidence or burden of early-stage prostate cancer [prostatic intraepithelial neoplasia (PIN)] and well-differentiated cancer (WDC) but not late-stage poorly differentiated cancer (PDC)., according to the University of Pittsburgh Cancer Institute and University of Pittsburgh School of Medicine(1)
In advanced prostate cancer stem-like cells, sulforaphane showed to inhibit tumor engraftment and tumor growth, without the induction of liver necrosis or other obvious side effects, In vivo(2).
In the comparison of the effect of sulforaphane(SFN) and 3,3′-diindolylmethane(DIM) in normal prostate epithelial cells and prostate cancer cells, researchers at the Oregon State University found that SFN and DIM reversed many of the cancer-associated methylation alterations, including aberrantly methylated genes that are dysregulated or are highly involved in cancer progression(3).

11. Sulforaphane and colon cancer
Bowel cancer is relatively very common and slowly growing and progress cancer and in predictable way. Bowel cancer is the third most commonly diagnosed cancer in developed countries, including US and Canada.
According to 1INRA, Laboratoire des Xénobiotiques, sulforaphane inhibited colon cancer cell line (HT29) through cell cycle arrest via an apoptotic process(1). GE132+Natural, a novel supplement consisting Resveratrol, Ganoderma lucidum, Sulforaphane, Lycopene and Royal jelly, in the testing of tested cancer cell lines (PC3, MCF7 and SW480), is found to be effective in inhibiting all tested cancer cell proliferation, the University of Belgrade insisted(2). Other study also showed the effective of sulforaphane and related dietary isothiocyanates in treating colon cancer cells via included cell growth arrest, autophagy and apoptosis depending to Depending on the isothiocyanates (ITCs) and treatment conditions(3).

12. Sulforaphane and cervical cancer
Cervix is the lower part of uterus that opens at the top of the vagina. Cervix acts an transition area for vaginal lining (squamous epithelium) change to uterus type (columnar epithelium) through the transitional area (squamous columnar epithelium) to host the development of the fetus. Cervical cancer is malignant neoplasm of the cervix uteri or cervical area caused by abnormal cells growth with alternation of cells DNA.
According to the Manipal University in the study of the effect of sulforaphane and eugenol effects on human cervical cancer cells, found that combined treatment with variable dose combinations resulted in differential effects with an antagonistic effect at lower and synergistic at higher sub-lethal doses as reflected in cell cytotoxicity and apoptosis induction(1). The Manipal University also showed that application of SFN inhibited human cervical cancer cell lines through apoptosis induction and anti-inflammatory properties(2). In human cervical carcinoma HeLa, treatment with SFN inhibit the cancer cell through down-regulation of anti-apoptotic Bcl-2 and Bcl-XL, and the up-regulation of pro-apoptotic Bax expression(3).

Chemical constituents
The vegetable chemical compounds containing include sterols (i.e. typical plant sterols, androstane, pregnane and cholestane derivatives, steroidal alkaloids and sapogenins), phytosterols, triterpenes, δ-amyrin, Chlorogenic acid, Nasunin and other Polyphenolic compounds.

1. Eggplant and cancer
Cancer is a class of diseases in which a group of cells growing and multiplying disordered and uncontrollable way in our body, have become progressively worse and damaged other healthy tissues, sometimes spreads to other organs in the body via lymph or blood and results may be in death.
The study of antiproliferative activities against human colon (HT29) and liver (HepG2) cancer cells conducted by Yeungnam University, the eggplant glycoalkaloids solamargine showed to inhibit both cancer cell lines but greater in colon cancer cell line(1). In human fibrosarcoma HT-1080 cell, delphinidin, a flavonoid pigment contained in the peel of eggplant, slightly inhibited tumor cell invasiveness probably through slight inhibition of the activity of MMPs(secretes matrix metalloproteinase)(2). According to Dr. Shimada A. in an one year (continuous 2 days for 12 months) food surveys held at 5 areas in Japan, the frequency of intake eggplant may associate to increase risk of gastric cancer and gastric cancer mortality rate(3), but may account partly for the geographic variation in gastric cancer mortality in Japan(4).

2. Eggplant and cholesterol
Cholesterol is needed for our body to build cell walls, make hormones and vitamin D, and create bile salts that help you digest fat. However too much of it can be dangerous because cholesterol cannot dissolve in your blood. The special particle called lipoprotein moves this waxy, soft substance from place to place. If you have too much low density lipoprotein LDL that is known as bad cholesterol, overtime cholesterol can build up in your arterial walls causing blockage and leading to heart attack and stroke.
Eggplant (Solanum melongena) has been used as hypocholesterolemic agent in many countries, including Brazil. its phenolic may has the potential to reduce hyperglycemia-induced pathogenesis linked to cellular oxidation stress(1). In a study of 38 hypercholesterolemic human volunteers ingesting S. melongena infusion for five weeks, researchers found no differences when compared to control, but in Intraindividual analysis S. melongena infusion significantly reduced the blood levels of total and LDL cholesterol and of apolipoprotein B(1).
But in a double-blind placebo-controlled study of the effectiveness of oral Solanum melongena (SM) against hyperlipidemia, showed the potential result in decreased serum total cholesterol, LDL-c and LDL-c/HDL-c, but no change in serum triglycerides, HDL-c, VLDL-c, AST, ALT, gGT, glucose and body mass index, after 3 months(2) and according to Universidade Federal de Minas Gerais, eggplant did not alter the total cholesterol and atherogenic lipoproteins after 12 week of intake in its study (3).

3. Eggplant as antioxidant
Free radicals are atoms, molecules, or ions with unpaired electrons through chemical bonds with other atoms or molecules during a chemical reaction. They may have positive, negative or zero charge. The unpaired electrons cause radicals to be highly chemically reactive in the human body, leading to aging and cancers.
Eggplant fruit contains a rich source of polyphenol compounds endowed with antioxidant properties. According to Università degli Studi di Catania, dry peeled skin combined with 50% aqueous ethanol, irradiated with microwave contained showed a high quantity of flavonoids with good antioxidant activity expressed through its capacity to scavenge superoxide anion and to inhibit lipid peroxidation(1). Solanum anguivi fruit (SAG) exhibited potent and concentration dependent free radical-scavenging activity as well as protected against Ca(2+) (110 μmol/L)-induced mitochondrial swelling and maintained the mitochondrial membrane potential, in the evaluation of the antioxidant and radical scavenging activities of Solanum anguivi fruit (SAG) and its possible effect on mitochondrial permeability transition pore(2).
The City University of New York, in the study of the antioxidant-caffeoylquinic acid isomers in fruits of wild eggplant relatives, 3-O-malonyl-5-O-(E)-caffeoylquinic acid (isomer 1) and 4-O-(E)-caffeoyl-5-O-malonylquinic acid (isomer 2) exhibited free radical scavenging activity, albeit about 4-fold lower than that of the flavonol quercetin dehydrate(3).

4. Eggplant and cardiovascular diseases
Beside cancer, heart disease kills more than 2,000 Americans everyday. Approximately 60 million Americans have heart disease. Most of heart diseases are caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat.

Animals fed freeze-dried products of either raw or grilled eggplants for 30 days study showed a positive effect of raw and cooked eggplant (Solanum melongena L) in increase left ventricular function, and reduce myocardial infarct size and cardiomyocyte apoptosis with high potency in grilled eggplants(1). According to Tuskegee University, eggplant containing high sources of phenolic compounds, which might provide anti-oxidative protection against free radicals in the human body and might reduce the risk of chronic diseases(2)

5. Eggplant and Type II diabetes
Diabetes is defined as a condition caused by insufficient insulin entering the bloodstream to regulate the glucose. It is either caused by cells in pancreas dying off or receptor sites clogged up by fat and cholesterol. In some cases, diabetes is also caused by allergic reactions of cells in the immune system.

According to University of Massachusetts, phenolic-enriched extracts of eggplant with moderate free radical scavenging-linked antioxidant activity had high alpha-glucosidase inhibitory activity, through inhibition of key enzymes relevant for type 2 diabetes and hypertension(1). Chlorogenic acids (CGAs (71 compounds), being esters of derivatives of cinnamic acids with quinic acid found in many foods, including eggplant may be associated to reduce risk of the risk of human chronic diseases such as inflammation, diabetes(2).

Ingredients
Guaianolides matricarin and achillin, acetoxyachillin and leucodin (= desacetoxymatricarin), corresponding C-11 stereoisomers(a),(Z)-2-β-d-glucopyranosyloxy-4-methoxycinnamic acid (cis-GMCA), chlorogenic acid, (E)-2-β-d-glucopyranosyloxy-4-methoxycinnamic acid (trans-GMCA), quercetagetin-7-O-β-d-glucopyranoside, luteolin-7-O-β-d-glucoside, apigenin-7-O-β-d-glucoside, chamaemeloside, apigenin 7-O-(6″-O-acetyl-β-d-glucopyranoside), apigenin] and one polyacetylene (tonghaosu)(b).

1. Chamomile and anti inflammatory effect
The immune system is the set of cells and their activity against antigens or infectious agents that comprises of the body’s defense system against diseases. The immune system does a great job of keeping people healthy and preventing infections. Beside foods and nutritional supplements, herbs also play a important role in helping the immune system defend against viruses and bacteria attacks.
In the study at Case Western Reserve University, showed its potential anti-inflammatory mechanisms, through inhibited NO production and iNOS gene expression via inhibiting RelA/p65 activation(1). The study of whether chamomile interferes with the COX-2 pathway, showed a positive effect of the herb in inhibition of COX-2 enzyme activity and causation of reduction in LPS-induced COX-2 mRNA and protein expression(2),
The study of supplement containing 2 flavonoids (>95% pure), luteolin (100 mg/capsule, from chamomile) and quercetin (70 mg/capsule), and the quercetin glycoside rutin (30 mg/capsule) from the Sophora japonica leaf, formulated in olive kernel oil to increase oral absorption, suggested that that the combination of the flavonoids luteolin and quercetin seemed to be effective in reducing ASD symptoms, with no major adverse effects through it anti inflammatory activities(3)

Insomnia is a sign and symptom of sleep disorder and defined as a condition in which a person has a difficulty falling asleep and/or staying asleep or sleep of poor quality that can lead to substantial impairments in the quality of life and functional capacity of an individual. Most adults have experienced insomnia sometimes in their life. According to statistic, more than 30% of the population suffers from insomnia, one in three people suffer from some form of insomnia during their lifetime and women suffer from insomnia more often than men.

Chamomile, one of most popular herb used for sleep disorders in herbal medicine. According to the Dr. Srivastava JK and research team at the Case Western Reserve University, many different preparations of the herb have been developed, the most popular of which is in the form of herbal tea consumed more than one million cups per day(1).
In a standardized chamomile extract for chronic primary insomnia study, in adults with chronic primary insomnia, the herb showed a modest benefits of daytime functioning and mixed benefits on sleep diary(2). According to DR. Wheatley D., the anxiolytic or sedative properties of chamomile chamomile, Ylang-Ylang) would appear to improve sleep, but how practical a form of treatment this may be remains to be determined(3).But in the assessing the benefits of chamomile in sleep time (TST), sleep efficiency, sleep latency, wake after sleep onset (WASO), sleep quality, and number of awakenings, researchers at the1University of Michigan, indicated that it may be the modest advantage on daytime functioning, but did not reach statistical significance(4).

6. Chamomile and skin cancer
Basal cell cancer is the most common type of skin cancer as a result of abnormal growth of the cells in the lowest layer of the epidermis. The cancer rarely spread and kill but can cause significant destruction and disfigurement to the affected skin area and accounted for more than 90% of all skin cancer in the U.S.
According to statistic, skin cancers accounted for approximately 40% of all cancers reported in the United States and approximately 9,500 deaths per year. Herbal chamomile showed to inhibited skin cancer cell lines through its antioxidant effects via inhibition of reactive oxygen species (ROS) type free radicals probably via downregulation of H2O2-generated free radicals in human skin fibroblasts (1). Apigenin , a chemical constituent of flavonoid found in chamomile, with 10 mumoles apigenin in 200 microliters DMSO:acetone (1:9) prior to each UVB exposure showed a promised resulted in reduction in cancer incidence (52% inhibition), through absorbing ultraviolet light or decreasing DNA damage(2). In support of the above, the National Taiwan University, indicated that a effectiveness of apigenin, in suppression of 12-0-tetradecanoyl-phorbol-13-acetate-(TPA)-mediated tumor promotion of mouse skin, through vary mechanisms(3).

Weight loss in Vitamin C Points of view

The prevalence of extreme overweight and obesity has caused concerns of scientific community in the South East Asian population, due unhealthy diet and life style change over 2 decades of economic prosperity. Overweight and obesity have reached epidemic proportions in many Asian countries, affecting even younger age than in Western populations with economic burden in the development of Obesity-related disorders such as diabetes, hypertension, and cardiovascular diseases(1). One of six Malaysian are either extreme overweight or obese, according to Datin Paduka Santha Kumari, chairman of the Selangor branch of the Malaysian Diabetes Association and according to global health observatory, at least 2.8 million people die each year as a result of being overweight or obese, and an estimated 35.8 million (2.3%) of global DALYs are caused by overweight or obesity, worldwide(2).
Epidemiological studies, linking herbal medicine, foods and vitamins in preventing and treating these diseases have been inconclusive(a)
Some researchers insisted that using herbs and supplements to induce weight loss should be taken with care, as a considerable number of reports have been published on hepatotoxicity associated with herbal products attributed with weight-reducing properties(4)(5)(6)(7). The College of Medicine, The Ohio State University insisted that various dietary, lifestyle, and psychologic factors are involved in the etiology of Prameha, particularly in relation to disturbances in fat and carbohydrate metabolism(8), without effective management, obtaining a workable weight loss plan may be extremely difficult.

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.

Vitamin C deficiency and incidence of obesity
Vitamin C and other nutrient deficiency not only is associated to the risk of Obesity(15) but also enhances the risk of lipids, inflammation and insulin resistance(16).
According to the research team at Universidad Autónoma de Querétaro, there is an associated link between Obesity and Zinc and vitamins A and C concentration in in women from rural Mexico, in a fasting blood sample analysis (11).
Although genetic susceptibility to obesity is associated with gene polymorphisms affecting biochemical pathways which also impacted by specific foods and nutrients. According to Dr. Johnston CS., vitamin C depletion is associated to positively related to body mass, individuals with adequate vitamin C status oxidize 30% more fat during a moderate exercise bout than individuals with low vitamin C status(10)

Vitamin C, the protective effect against obesity
Endothelial dysfunction has found to be associated to the incidence of obesity(12). The study of 76 healthy subjects (50 men and 26 women aged 21-45 years) obese subject, showed a positive effect of vitamin C and indomethacin in reduced oxidative stress contributed to endothelial dysfunction in human obesity(13).
In the evaluation of the potential inhibitory activity on α-glucosidase and pancreatic lipase by Citrus spp. fruits of Spanish origin, grapefruit, contained higher contents of phytochemicals such as vitamin C, is found to have a great value for nutrition and treatment of diet-related diseases(14).
L-Ascorbic acid in the study, whether would facilitate the anti-obesity effects of chitosan and psyllium husk in vivo, showed addition of vitamin C in diet influenced the reduction in body weight gain and food efficiency ratio, and the increase in total fecal weight and fecal fat excretion in guinea pigs fed a high-fat diet(16).

Taken altogether, deficiency of vitamin C and other nutrient is associated to increased risk obese incidence. Vitamin C may be effective in induced weight loss for obese subjects due tom its positive interaction in inhibiting oxidative stress causes of endothelial dysfunction. Daily ingestion of high-dose vitamin C may be considered safe, but in rare incidence, overdoses in a prolonged period of time, may cause intra-renal oxalate crystal deposition, a fatal nephrotoxicity(18)(19).
