Selenium is a trace mineral that affects the health and performance of the body in stressful conditions. There are limited studies on the effects of different doses of selenium in long-term heat stress conditions on physiological parameters and health indicators. This study was conducted to determine the effects of different doses of selenium from selenium-methionine supplement on the antioxidant status (glutathione concentration, activity of superoxide dismutase and glutathione peroxidase), liver and kidney health index (the activity of transferase enzymes and creatinine concentration) and concentration of metabolism-related hormones (insulin, cortisol, triiodothyronine and tetra-iodothyronine).Materials and methods: In a completely randomized design, 25 female rats were randomly divided into five groups and five replicates. Five rats were placed at standard temperature during the experiment period and the rest of the rats were placed under heat stress (38 ± 2 °C for 6 hours/day). Rats in the negative control group (without heat stress) and positive control (heat stress) were fed with standard pellets without additive and the other three groups were fed with standard pellets plus 0.15, 0.30 and 0.45 mg selenium/kg as a selenium-methionine supplement for 30 days.Results: Rats receiving selenium had more hemoglobin and alanine transaminase enzyme activity (P=0.001) compared to the positive control group. Cortisol concentration in the positive control group was higher than the negative control group (P=0.001). Adding selenium to the diet of rats under heat stress decreased (P=0.001) the concentration of cortisol, and increased the concentration of insulin and triiodothyronine compared to the positive control group. The serum malondialdehyde of the positive control was higher than the negative control and other experimental groups (P=0.001).Conclusion: According to the results of this study, heat stress causes oxidative stress in the body and causes changes in the hormonal concentration and the activity of the body's enzymes. In overall, it can be concluded that higher selenium supplementation (0.45 mg/kg) is optimal for improving the liver and kidney indices, hormone concentration and antioxidant response in rats under heat stress conditions.

The CX group participated in a 10-week CX training program with 3 sessions per week, and the control group was prohibited from participating in any sports activities. Fasting levels of glucose, insulin, insulin sensitivity and glycosylated hemoglobin (HbA1C) and anthropometric indices were measured in both groups before and after the training period. Fasting blood samples were also taken before and 48 hours after the last training session with the aim of measuring dependent variables in both groups.Results: 10 weeks of CX training led to a significant decrease in glucose, insulin and glycosylated hemoglobin and a significant increase in insulin sensitivity in obese pre-diabetic women compared to the control group. CX training also did not result in a significant decrease in body fat percentage compared to the control group.Conclusion: The implementation of CX exercises as one of the new methods of resistance training is associated with the improvement of diabetes indicators in obese pre-diabetic women. Therefore, it is suggested to perform such exercises for a relatively long period with the aim of improving the glycemic profile Manuscript profile -

The subjects were divided into experimental (n=15) and control groups (n=15). The experimental group performed eight weeks of hypoxic interval training and the control group had no exercise program. In the practice of hypoxia (breathing control), the subject breathes consciously and purposefully that his body is exposed to mild and intangible oxygen deficiency. Blood sampling was performed to determine hemoglobin and hematocrit. Arterial heart rate and arterial oxygen saturation were measured with a finger pulse oximeter and acute mountain sickness was measured using the Lake Louise questionnaire. Results: Independent t-test results showed that eight weeks of interval hypoxic training at sea level showed a significant difference in arterial blood oxygen saturation (p=0.000), hemoglobin (p=0.000), hematocrit (p=0.000) and a significant decrease in resting heart rate (p=0.000) and Symptoms of amateur mountaineers’ acute mountain sickness in the experimental group compared to the control group (p<0.05).Conclusion: Interval Hypoxia Training at sea level is an effective exercise to prepare amateur mountaineers for high altitudes and to prevent acute mountain sickness Manuscript profile -

Adult hemoglobin (HbA) contains 2 Alfa Globin and 2 Beta Globin chains (andalpha;2andbeta;2) while Fetal hemoglobin (HbF) contains 2 Alfa Globin and 2 Gamma Globin chains (andalpha;2andgamma;2). HbF switches to HbA in early weeks after the birth. A kind of andbeta;-thalassemia is HPFH phynotype. In these patients the level of HbF will be high in after the birth continuously. The gamma globin gene is in beta globin gene cluster and its expression will be control by locus control region (LCR) which located in upstream of beta gene cluster. The LCR composed of five DNase I hyper sensitive sites (HS1-5) in Erythroid cells. We amplified HS2, HS3, HS4 segments (mini LCR) and andgamma;-globin gene from the genomic DNA of a normal individual by PCR. Each of segments cloned in pTZ57R/T vector and then subcloned in the pBGGT vector, a derivative of PUC19 plasmid. This construct is a positive control and containing 5and#39; HS4,HS3,HS2 3and#39; segments (mini LCR, 4 kb) and A Gamma gene (2 kb). That could be used in studying of some mutations which due to HPFH phenotype and affect expression of andgamma;-globin gene and also for induction of HbF production in gene therapy of andbeta;-thalassemia.
