Abstract
Background and Objective: Resistance to antiretroviral agents is a significant concern in clinical management of HIV-infected individuals. Resistance is the result of mutations that develops in the viral protein targeted by antiretroviral agents.
Material and Methods: In this cross-sectional study, the blood samples of 40 HIV-positive patients were collected. Twenty of them were drug-naïve and the rest were under treatment for at least one year by antiretroviral agents. Virus genome was extracted from patient's plasma with high-pure-viral-nucleic-acid kit. Then, by means of reverse-transcriptase and specific primers of protease genes were amplified and sequenced. Sequences of genes, drug- antiretroviral- resistant mutations and subtypes were determined using Stanford University’s HIV-drug-resistance databases.
Results: Drug-naive patients show 15% resistance to nucleoside-reverse-transcriptase inhibitor (NRTI) and 20% resistance to non-nucleoside-reverse-transcriptase inhibitor (NNRTI). Anti-protease resistance is not observed in any patients. In under treatment patients, drug resistance to NNRTI (25%) is more than drug resistance to NRTI (20%) and the rate of drug resistance to protease inhibitor is 5%.
Conclusion: Our findings show a high prevalence of drug-resistant mutations in Iranian-drug-naïve-HIV-infected patients. But in under treatment individuals, the rate of drug resistance is less than previous studies.

Abstract
Background and Objective: Diabetes mellitus is one of complications that thalassemia major patients face with. Hence, blood glucose monitoring is of vital importance to these patients. Because of high level of fetal hemoglobin in these patients, the measurement of hemoglobin A1c is not reliable and should be displaced by fructosamine test.
Material and Methods: The current descriptive study was carried out on 33 beta-thalassemia major patients afflicted with diabetes mellitus (21 female and 12 male cases). Blood glucose level, fructosamine, hemoglobin A1c, serum ferritin and fetal hemoglobin were measured.
Results: Blood glucose levels are 204±103 mg/dL and 221±101 mg/dL (p=0.63) fetal hemoglobin levels are 9%±7% and 13%±9% (p=0.22) serum ferritin levels are 1744±1534 ng/mL and 3253±1773 ng/mL (p=0.96) in female and male patients, respectively. The level of fructosamine (42±124 mmol/L) and glycosylated hemoglobin (8.9%±1.8%) are correlated significantly (r=0.69, p<0.01). Both Hemoglobin A1c (r=0.75, p<0.01) and fructosamine (r=0.54, p<0/01) show a significant correlation with blood glucose level.
Conclusion: In diabetic thalassemia major patients with frequent blood transfusion, the level of fructosamine and glycosylated hemoglobin are related significantly, therefore they can be used alternatively.

Abstract
Background and Objective: Celiac is an autoimmune disease that is characterized by an immune-system-related damage in the intestinal tissue after consumption of gluten. There is not any general agreement for gold standard. The Purpose of this study was the evaluation of specificity and sensitivity of anti-endomysial (EMA) and anti-tissue transglutaminase (TTG) serological test compared to small-bowel biopsy.
Material and Methods: In the cross sectional study, we took blood specimen from 1825 patients with gastrointestinal disease. All the samples were tested by TTG and EMA kits using ELISA. The patients were studied in two groups. First, the individuals whom their serologic test was positive but their tissue condition was normal and second, those with positive serologic test with pathologic tissue results that show they have celiac disorder.
Results: The mean of EMA and TTG shows that the level of antibodies in group 2 is significantly higher than that of the first group (P ≤0.001). There is positive correlation between modified marsh criteria of small-bowel biopsy and the two tests. The Sensitivity of EMA and TTG tests for celiac diagnosis is 92%. The specificity of EMA, TTG tests are 100% and 98.5%, respectively.
Conclusion: EMA-IgA serology with cut-off point of more than 66 together with TTG-IgA serology with cut-off point of above 30 can be helpful to distinguish a wide range of patients who need small-bowel biopsy.

Abstract
Background and Objective: One of the diabetes complications is the tissue damage caused by the imbalance of oxidants and antioxidants (oxidative stress). The aim of the present study was to evaluate the activity of two antioxidant enzymes -superoxide dismutase and catalase- in the serum of streptozotocin-induced diabetic rats.
Material and Methods: This investigation was conducted on adult male rats assigned to diabetic and control groups. Diabetes was induced by a single intraperitoneal injection of streptozotocin. Seven weeks after diabetes induction, glucose concentration, superoxide dismutase and catalase activities of the serum were assessed.
Results: Glucose concentration of streptozotocin-injected animals was significantly higher than that of control group (P<0.001). The level of Serum superoxide dismutase and catalase activities in diabetes group were significantly higher than those in control group (P<0.01). There was a positive significant correlation between glucose concentration and superoxide dismutase and catalase activities (P<0.001).
Conclusion: The high activity of antioxidant enzymes in diabetic rats is probably due to compensation responses to oxidative stress produced by high concentration of free radicals. It seems that the higher glucose concentration, the greater compensatory responses.

Background and Objective: Flavonoids play an important role in non-enzymatic reaction against oxidative stress. These are polyphenolic compounds in tea structure that could be reacted with free radicals and neutralized them. In this study, we investigated the anti-oxidant impact of Camellia Sinesis on the liver of thioacetamide -injected male albino mice.
Material and Methods: In this study, 40 male mice were categorized in five groups of eight. The first group was control. The second and the third group received 100mg/kg and 150mg/kg of thioacetamide, respectively. The fourth group received 100mg/kg thioacetamide followed by black tea (5 gr/100) and the fifth one received 150mg/kg thioacetamide followed by black tea (5 gr/100). Tioacetamide was given via intraperitoneal. After that, for 30 days, they were only fed on black tea (5 gr/100). At the end, catalase (CAT) and glutathione peroxidase (GPx) activity were measured.
Results: Based on the results, catalase(CAT) and glutathione peroxidase(GPx) activity were significantly increased in the groups of Thioacetamide and black tea compared to those of only Thioacetamide groups (p<0.05).
Conclusion: The increase of these enzymes in tea groups shows the anti-oxidant effect of black tea that can be caused by Catechin.

Abstract
Background and Objective: Carbohydrates are considered as the major source of energy in physical activity. Studies show that consumption of carbohydrate foods before exercise can balance blood glucose and free fatty acids and increase athletes’ performance. In this study , we compared the effect of three kinds of foods with different glycemic indices on blood glucose (BG) and serum free fatty acids (FFA) in cycling ,male athletes.
Material and Methods: In this clinical trial, 21 members of national cycling team randomly allocated to three equal groups of glucose (low glycemic index) ، lentil (low glycemic index) and potato (high glycemic index). First, Fasting blood samples (5ml) were obtained to measure BG and FFA . Then the subjects were asked to eat their foods. After 45 mins of rest, they pedaled with maximal oxygen consumption VO2max) for two hours and again their blood samples were taken to compare with the levels of before interventions.
Results: Glucose consumption resulted in a significant decrease in FFA level after 2 hours of pedaling (P = 0.01) but no significant change in BG level. Plasma glucose was higher after eating lentil than that of potato (P<0.05), but it was not true for FFA level of both groups.
Conclusion: based on the results, the pre-exercise use of low glycemic index (lentil) compared to high glycemic index (potato) can better lead to increased blood glucose during exercise.
