They are found in foods derived from ruminants (beef and lamb as well as dairy products from these sources). When a mixture of isomers is fed to experimental animals, chemically induced cancer, tumorogenesis in mammary gland, colon and skin is decreased. Mechanisms of inhibition of carcinogenesis may include reduction of cell proliferation, induction of apoptosis and alterations in the components of the cell cycle. In addition, CLAs modulate markers of immunity and also eicosanoid formation in numerous species as well as lipid metabolism and gene expression. It is likely that CLAs exert inhibitory properties in carcinogenesis via one or more of these pathways. This review will explain recent advances byexploring the putative mechanisms of reduction of carcinogenesis by CLAs.

The aim of this study was to investigate the association between C677T polymorphism in MTHFR gene and some non-genetic factors and varicose veins. Methods: In this case-control study, 80 patients with varicose veins and 150 healthy subjects were studied. After extraction of DNA from peripheral blood, genotyping was performed by PCR-RFLP. Demographic data such as family history, sex, age, weight, work duration, defecation status, exercise, blood pressure, cigarette smoking were also recorded. Logistic regression method was used to investigate the association between varicose veins disease and C677T genotypes and other recorded variables. Results: Genotype frequencies of C677T in MTHFR gene in patients and control groups was not significantly different (p>0.05). The frequency of mutant allele in two groups was equal to 19%. The association between C577T genotype and varicose veins was not significant (p>0.05), however family history, weight, work duration and constipation was related to varicose veins (p<0.05). There was no association between varicose veins and exercise, age, blood pressure, sex and cigarette smoking (p>0.05). Conclusion: The polymorphism of C677T in MTHFR gene was not a determinant factor of the varicose veins disease in Mazandaran population.   4859 Exercise Physiology The Effect of 8-Week Aerobic Exercise and Consumption of Omega-3 Supplement on Pulmonary Function in Obese Men Sharifan Salah g Vakili Javad h Sari-Sarraf Vahid i Rasoulpour Jamal j Gharani Hadi k g University of Tabriz , Tabriz, Iran h University of Tabriz , Tabriz, Iran i University of Tabriz , Tabriz, Iran j University of Tabriz , Tabriz, Iran k University of Urmia , Urmia, Iran 1 10 2018 25 7 27 37 12 06 2017 29 05 2018 Background: Inactivity and obesity are of the consequences of industrial life, as the trend of increasing prevalence of obesity has negative effects on the respiratory system. Aerobic exercises and omega-3 fatty acids are paid close attention due to their physiological effects on different systems of the body. The present study was carried out in order to examine the effect of 8-week aerobic exercise and consumption of omega-3 supplement on pulmonary function in obese men. Methods: In this semi-experimental study, 40 obese men with average age of 32.3±3.05 years, weight of 97.8±7.4 kg, waist-hip ratio of 1.01±0.022, Body Fat of 31.53±2.52 Percent and BMI of 32.3±2.61 kg/m2 were randomly assigned into 4 groups of 10 participants: placebo, supplement, training-placebo, training-supplement. Aerobic training program consisted of running with intensity of 55-85% HRmax for 8 weeks, 25-45 minutes and thrice a week. Amount of consuming supplement daily 1000 mg of omega-3 and placebo was also 2% dextrose. The values of variables were measured 48 hours before and after the exercises. Data analysis was carried out using two-way ANOVA and Bonferroni post hoc test at a significance level of 5%. Results: The effect of the exercise on body fat percentage weight decrease was significant without considering the effect of the supplement (p<0.05). Exercise and supplement caused a significant increase in the values of FVC, FEV1, PEF, FEF25-75, FIV1, and PIF (p<0.05). The effect of the exercise on the increase in VO2max and PEF was significant without considering the effect of the supplement (p<0.05). Exercise, supplement, and combination of exercise and supplement had no significant effect on the size of chest circumference at both inspiration and expiration (p>0.05). Conclusion: Regular aerobic exercise and consumption of omega-3 are two modifying and effective factors in increasing respiratory parameters; therefore, they improve respiratory status in obese men.   5130 Genetic Mutations Analysis of exon 10 - 11 of phenylalanine Hydroxylase gene in phenylketonuria patients from Golestan province Haerian Ardakani Hossein l khazaei koohpar zeinab m Mohammadian Sakineh n l Tonekabon Branch, Islamic Azad University, Tonekabon, Iran. m Tonekabon Branch, Islamic Azad University, Tonekabon, Iran. n Golestan University of Medical Sciences, Gorgan, Iran. 1 10 2018 25 7 38 46 06 01 2018 10 06 2018 Background: Phenylketonuria (PKU), the most common inborn error of aminoacid metabolism, is an autosomal recessive disorder caused by more than 600 mutations in Phenylalanine Hydroxylase gene (PAH). Distribution pattern of mutations in the PAH gene are specific to each population. The aim of this study was to identify mutations in exons 10 and 11 of the PAH gene in patients with PKU from Golestan Province and compare it with the studies in other parts of Iran. Methods: This study is a cross-sectional descriptive study. During a one-year period, twenty- six unrelated PKU patients were identified from different regions of Golestan province. Genomic DNA was extracted from leukocytes using High Pure- Template PCR kit (Roche) and polymerase chain reaction – sequencing method was applied to detect mutations. Results: The identified mutations in this study are: IVS10-11G>A (19.23%) and IVS11+1G>C (7.7%). These patients had classic PKU phenotype. Conclusion: The high frequency of IVS10-11G>A mutation in Golestan province may be related to genetic drift, founder effect, and consanguinity. Moreover investigation of mutations in PAH gene can be a useful tool for molecular detection of PKU disease and carrier detection in this population.   5073 Microbiology Effects of Prostate Cancer Immunotherapy On esp Gene Expression of Enterococcus Faecalis Talebzadeh Tayebeh o Baghbani-Arani Fahimeh p Houshmand Masoud o Islamic Azad University, Varamin, Iran. p Islamic Azad University, Varamin, Iran National Institute of Genetic Engineering and Biotechnology (NIGEB), Tehran, Iran. 1 10 2018 25 7 47 54 18 11 2017 11 06 2018 Background: Prostate cancer is the most commonly diagnosed malignancy and the second leading cause of cancer deaths among men in the world. Immunotherapy is a new, non-invasive and effective method for the treatment of cancer, but its side effects on the normal flora of bacteria and opportunistic infections not known yet. The aim of this study was to evaluate the effects of immunotherapy on Enterococcus faecalis (E. faecalis) virulence gene expression in patients with prostate cancer. Methods: In this study, the effect of prostate cancer immunotherapy on the expression level of enterococcal surface protein (esp) gene which is involved in Enterococcus faecalis pathogenesis were investigated. For this purpose, the samples were analysed in three groups; normal individuals 211 men), prostate cancer patients (176 men) before and six months after immunotherapy period. Results: Results showed significant (p=0.00) over expression of esp gene in prostate cancer patients after immunotherapy. There was no significant difference between prostate cancer patients before immunotherapy and healthy subjects. Conclusion: We conclude from these findings that immunotherapy could play a major role in increasing the pathogenicity risk of E. faecalis as a normal microflora. According to current results we suggest that using antibiotic administration in the period of immunotherapy prevents the possibility of opportunistic bacterial infections including E. faecalis.     5102 Psychiatric Occupational therapy The effect of extroceptive and proprioceptive sensory stimulation on ADL and motor function of upper limb in stroke patients Derakhshanfar Maryamn Raji Parvin Bagheri Hossein Jalili Mahmood Tarhsaz Hossein Tehran University of Medical Sciences, Tehran, Iran.

Various studies have reported the prevalence of these deficits in stroke patients between 11 and 85%. These defects in the upper limb of the hemiplegic vary from the lack of primary senses to more complex perceptions, and they reduce the use of the affected limb. Weakness in fine motor manipulation of objects, weakness in the skills of grasping, decrease in the level of activity on the affected side and ultimately a decrease in the quality of life of the individual are seen. The purpose of this study was to evaluate the effect of extroceptive and proprioceptive sensory stimulation on daily living activity and motor function of upper limb in stroke patients. Methods: This interventional study was a blind clinical trial that was performed on 60 patients with chronic stroke. Upper limb function (Fugle-Meyer test) and daily living activity (Barthel test) were evaluated. Patients received extroceptive and proprioceptive sensory stimulation for 6 weeks. Treatment was based on the Rood approach. Results: The results of this study showed that the intervention group had significant improvement in motor function (p<0.0001) and daily living activity of upper limb (p<0.0001). Conclusion: Based on the results, it can be implied that extroceptive and proprioceptive sensory stimulation are effective methods in improvement of motor function and daily living activity of the stroke patient’s upper limb.   5105 Immunology Assessment of hepatitis B viruses serologic markers in special patients (thalassemia and dialysis) of Mazandaran province Mohamadnezhad Sara amirmozafari Nour asmar mehdi nasrolahi mohtaram Islamic Azad university, Sari, Iran Iran University of Medical Sciences, Tehran, Iran.
