Using an open-label design, we evaluated the impact of a DAA/sodium nitrate/ vitamin D3 dietary supplement on blood testosterone and nitrate/nitrite, as well as subjective indicators of health, in middle-aged men. Methods: 10 overweight or obese men (mean age: 42 years) were assigned to ingest a DAA/sodium nitrate/ vitamin D3 supplement (either one or two servings per day) for 28 days. Blood total and free testosterone and nitrate/nitrite was measured before and after 14 and 28 days of supplementation. Subjective assessment of to health indicators (e.g., energy level, libido) was included at each collection time. Results: Total and free testosterone increased on average 5-10%, which was not of statistical significance (p>0.05). The response was highly variable; some men failed to respond to treatment, while men with relatively low basal testosterone values experienced increases exceeding 20%. Plasma nitrate/nitrite was increased approximately 6-10 fold after treatment with the supplement, with a trend noted for a time effect (p=0.07). Men reported a significantly better feeling following supplement use, as evidenced by a time effect for both vitality (p=0.02) and libido (p=0.04), with a trend noted for increased energy level (p=0.08) and mental outlook and mood (p=0.10). Conclusion: Twenty-eight days of treatment with a DAA/sodium nitrate/ vitamin D3 dietary supplement increased blood nitrate/nitrite and improved subjective feelings of vitality and libido in middle-aged men. In selected men with low basal testosterone values, the supplement increased circulating levels of this hormone.","PeriodicalId":89504,"journal":{"name":"The open nutraceuticals journal","volume":"8 1","pages":"43-48"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68134586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have only scanty information about functional foods which may be considered as nutraceuticals. The prevalence of optimal functional food eating behavior pattern in the population is unknown. This study examines the prevalence of optimal functional foods eating behavior as a protective factor among victims dying due to NCDs to find out the accuracy of the verbal autopsy questionnaire. Subjects and Methods: Death records of 2,222 (1,385 men and 837 women) decedents, aged 25-64 years, out of 3,034 death records, were randomly selected and studied by verbal autopsy questionnaires. All the risk factors and protective factors were assessed by questionnaires which were completed with the help of the victim's spouse and a local treating doctor, by a trained scientist. The lack of knowledge on health education about the role of adverse effects of Western foods was assessed by the questionnaires. Functional food intake was considered in presence of fruit, vegetable and legume intake of minimum 250g/day (moderate) and ideally 400g/day consistent with WHO guidelines. Results: The prevalence of optimal prudent foods intake behavior; fruit, vegetable and legume (>250g/day) intake were observed among 51.4% (n=712) men and 50.4% (n=422) women. Western type food (>255g/day)intake was observed among 63.2% (n=875)men and 59.9% (n=502) women. The prevalence of optimal functional food intake was significantly greater among men compared to women (19.4 vs 14.6%, P<0.05). The consumption of functional food not fruits; grapes and apples, guava, stargoose berry and lemon and onion, garlic ginger was significantly greater among men as compared to women. Other functional foods such as soy products, mustard or olive oil, curd or yogurt, nuts and fish, tea and cocoa, spices; turmeric, cumin, coriander seeds and peppers intake showed no significant difference between two sexes. Multivariate logistic regression analysis revealed that after adjustment of age and body weight, total functional foods intakes and fruit, vegetable, legume and nuts intake were significantly inversely associated with deaths due to NCDs, whereas Western type foods (red meat and eggs, refined foods ) were positively associated with these causes of deaths, in both sexes. Total spices intake, mustard/olive oil intake and curd or yogurt intake, were inversely but weakly associated with causes of deaths due to NCDs, among both men and women. The prevalence of protective behavior pattern was observed among half of the victims, dying due to injury and accidents where such behaviors were uncommon among decedents dying due to NCDs.

This damage to both structure and function may be accelerated by smoking, alcohol consumption and chronic sun exposure (extrinsic components). All these factors may lead to the formation of wrinkles, the appearance of brown spots and skin thickening. One effective strategy to managing the skin ageing process is adopting a healthy nutritional approach to life, maintaining a balanced diet and a good supply of food supplements. This can restore the homeostasis of macro and micronutrients and support the physiology of cells and tissues in the skin. Hydrolysed collagen, an increasingly popular nutraceutical, is composed of low molecular weight small peptides, which are easily digestible, absorbed and distributed in the human body. Numerous clinical trials have now been performed showing the efficacy and benefits of collagen peptides on skin properties, such as hydration, elasticity and reduction of wrinkles. As a result, hydrolysed collagen can be considered an important weapon in the everyday fight against skin ageing.","PeriodicalId":89504,"journal":{"name":"The open nutraceuticals journal","volume":"8 1","pages":"29-42"},"PeriodicalIF":0.0,"publicationDate":"2015-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68134562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results demonstrated that supplementation increased the number and proportion of hematopoietic stem cells (HSC) in the blood, suggesting there was effective release of stem cells from the bone marrow niche into the circulation. Analysis of bone marrow cells showed a concomitant reduction in the proportion of total HSC, however within the HSC compartment there was a relative increase of CD34 + c-Kit + and reduction in CD34 + Sca-1 + HSC subsets. Mesenchymal/stromal stem cell (CD105 + CD29 + ) numbers showed a decrease in the peripheral blood, with an increased proportion detected in the bone marrow. Alpha Lipid Colostem supplementation also correlated with increased the number of blood granulocytes demonstrating enhancement of hematopoietic stem cell differentiation.

The effects of ()Sch B and curcumin (Cur), resveratrol (Rev) and epigallocatechin gallate (EGCG) on -amyloid (A)-induced apoptosis were investigated in SH-SY5Y cells. Cellular reduced glutathione (GSH) levels and peroxide-induced GSH depletion were measured. Activities of glutathione reductase (GR) and glucose-6-phosphate dehydrogenase (G6DPH) in Aβ-challenged cells were also examined. All tested phytochemicals were investigated for the activation of nuclear factor erythroid-2 related factor 2 (Nrf2) in SH-SY5Y cells, using a luciferase-based assay. Finally, they were examined for the effect on the extent of phosphorylation of Tau in A- challenged cells. The results showed that only ()Sch B and EGCG protected against Aβ-induced apoptosis in SH-SY5Y cells. The cytoprotection afforded by ()Sch B and EGCG were associated with an increase in cellular GSH levels in Aβ- challenged cells and a reduction in peroxide-induced GSH depletion. However, only ()Sch B, but not EGCG, increased G6DPH and GR activities in Aβ-challenged cells and caused the activation of Nrf2 in unchallenged cells. Both ()Sch B and EGCG reduced the extent of Tau phosphorylayion in Aβ-challenged cells. In conclusion, ()Sch B may enhance cellular glutathione redox cycling, presumably by increasing G6PDH and GR activities, via activation of the Nrf2 signaling pathway, whereas EGCG likely acts as a radical scavenger. Both ()Sch B and EGCG suppressed the phosphorylation of Tau in Aβ-challenged cells, suggesting their potential in ameliorating the pathological condition of Alzheimer's disease.","PeriodicalId":89504,"journal":{"name":"The open nutraceuticals journal","volume":"7 1","pages":"49-57"},"PeriodicalIF":0.0,"publicationDate":"2014-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68134370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the exponential nature of the relation between average alcohol consumption and mortality has been demonstrated in Russia. This study revealed that substantial numbers of people report drinking three or more half-litre bottles of vodka per week. However, the exponential curves for dose-response relations between average volume of alcohol consumption and the mortality risk of various diseases is not fully explained. The variation in mortality may be due to presence of confounders such as physical activity, greater consumption of fish and salads which are rich sources of omega-3 fatty acids and polyphenolics. It is possible that patients with type 2 diabetes, moderate alcohol us-e, particularly wine consumption, is associated with reduced risks of cardiovascular events and all-cause mortality. Serge C. Renaud gave the definition of the French paradox and suggested that the inhibition of platelet reactivity by wine may be one explanation for protection from CAD in France. It is known that aging of alcohol also increases 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity and therefore moderate drinking of aged whisky and other alcoholic drinks in moderation may provide beneficial effects. Excess of alcohol intake causes decreases in vitamin B1, B6 and B12 as well as in folic acid, antioxidants vitamins A,E ,C and beta carotene, flavonoids, amino acids, coenzyme Q10, l-carnitine, omega-3 fatty acids as well as in minerals magnesium, potassium, calcium, copper, zinc, chromium and selenium. Alcoholism also has a direct adverse effects on cell membrane, mitochondria and genes. Alcoholic cirrhosis, fatty liver, cardiomyopathy, hypertriglyceridemia, hyperuricemia, oxidative stress and inflammation are well known adverse effects of alcoholism. It also damages the brain causing dementia, depression and psychosis. However, moderate alcohol intake up to 10 drinks per week may have beneficial effects on the risk of all these problems. Moderate alcohol intake increases HDL-C, and decreases C-reactive proteins, IL-6, TNF-alpha, Lp (a), plasminogen activator inhibiter-1, insulin resistance which are risk markers of CVDs, type 2 diabetes and cancer. These beneficial effects are enhanced by omega-3 fatty acids and polyphenolics that are rich in Mediterranean style diets. Vodka and spirits can be made healthly if enriched with fish oil or alpha- linolenic acid (rich source of w-3) and cocoa (flavanol) which can repair this deficiency.
