Background: Although a few studies have shown the positive correlation between patients’ serum concentration of 25 OH-VITAMIN D3 and type II diabetes mellitus, metabolic syndrome, and insulin resistance, there are controversies regarding the relationship between 25 OH-VITAMIN D3 as a risk factor for cardiovascular atherosclerotic diseases that has to be cleared. The aim of this study was to evaluate the association between the rate of 25 OH-VITAMIN D3 and the presence and severity of coronary artery disease (CAD) in Patients with suspected CAD.Methods: This study was a cross sectional study that has been conducted in the department of cardiology in Imam Khomeini Hospital complex in collaboration with endocrinology research center. In this study 178 patients with suspected coronary artery disease (CAD) were enrolled. Based on their history and clinical findings coronary angiography was performed in all patients. Severity of CAD has been assessed by using Gensini score, based on their coronary angiography findings. The relationship between severity of CAD and their serum level of 25 OH-VITAMIN D3 was evaluated. Serum level of 25OH- VITAMIN D3 was measured by the enzyme-linked immunosorbent assay (ELISA) method by Euroimmiune kits (from Germany).Results: Of 178 patients, 50 (28.1%) were female and 128 (71.9%) were male. Mean±SD of their ages was 56.2±11.8 years old. Significant coronary artery stenosis (stenosis more than 50% luminal diameter) was observed in 91 (51.1%) of patients. Mean±SD of serum level of VITAMIN D3 in patients with CAD was 45±35 nm/l and in patients without CAD was 55±44 nm/l (P= 0.047). Mean±SD of Gensini score was 26.3±21.1, as well. Therefore correlation coefficient between 25 OH-VITAMIN D3 and Gensini score was -0.262 (P= 0.043).Conclusion: Although there is a trend toward association between deficiencies of 25 OH-VITAMIN D3 and the presence of CAD but their association is not statistically significant. For achieving more convincing findings larger studies are needed.

Introduction: Fertility means the ability to have a child that is one of the causes of family formation. Several factors can affect fertility. Micronutrients are essential for the body's anabolic and catabolic activities, so they may be effective factors on fertility. Therefore, this study was conducted with aim to determine the role of micronutrients in male and female fertility. Methods: In this review study, the Persian databases of Magiran, SID and the English databases of Pubmed, Scopus, SID, Elsevier, Web Of Sciences and the Google Scholar search engine were searched using the English keywords of Infertility, fertility Infertility, Fertility, Male Infertility, Semen, Semen Parameters, Systematic Review, Clinical Trial, Case-Control, Female Infertility, Micronutrients, VITAMIN A, VITAMIN B, VITAMIN C, Ascorbic Acid, VITAMIN D, VITAMIN E, Antioxidants, Folic Acid, Zinc and their Persian equivalents in the period of 1990-2020. Numerous quantitative and qualitative studies that were similar to the present study in terms of content were selected and evaluated. Results: Among 1052 articles, 22 studies which were more related to the aim of the present study were selected and evaluated. The results of reviewing the studies showed that the consumption of micronutrients including VITAMINs D, E, C, A, zinc, iodine, selenium, folate and omega-3 fatty acids can play a role in improving male and female fertility parameters. Deficiency of each of them has been seen in infertile men and women. Conclusion: Since nutrition has moved towards ready meals and lifestyle has moved towards a sedentary life and as a result, the body does not meet the essential needs for basic activities, it seems that the recommendation to consume micronutrients in men and women can prevent many fertility problems and reduce the cost of infertility treatment.

In order to study the effects of VITAMIN E, VITAMIN C or combination of VITAMIN E and C supplement on bioenergetic index (aerobic and anaerobic power). 36 physical education college students (male) were selected non randomly and divided into 4 groups randomly. Average age, weight, height and fat percentage were (22.48±1/84) years, (64.93±7.84) Kg, (175.4±5.66) cm and (1094±5.29) mm respectively. The period considered for consumption of VITAMINs by experimental group was 3 weeks. During this period, the first group consumed 400m.g VITAMIN E and second group 1000m.gVITAMIN C and third group 400m.g VE plus 1000 mg VC daily and fourth group (control group) consumed placebo. The test in this research consists of assessment of anaerobic power by «Rast», test 2 assessment of aerobic power by Cooper test.
