Different incidence and severity of this viral disease among various age range and individuals with different background disease may indicate the pivotal role of host genetic factors in their prevalence and mortality rate. In this regards, present study was performed to review the most important genetic variants and factors in incidence and severity of SARS-CoV-2 based on the carried out studies in various populations.   Materials and methods: Databases including PubMed, PubMed Central, Google Scholar, Bing, medRxiv and COVID-19 host genetics initiative were explored using key words including gene polymorphism, gene expression, gene variant, infection risk and disease severity to find the papers regarding genetic factors association with SARS-CoV-2 and its severity. Results and Conclusion: Its seems that in addition to the HLA system variants and the genes related to interferons as well as IFITM3, ACE2, TMPRSS2, CD147, ACE and TLR7 genes are the most important genes which are involved in SARS-CoV-2 pathogenesis. Investigating the association of the most important genetic variants among different populations with SARS-Cov-2 can provide the way towards more targeted therapies for this disease. Moreover, by recognizing those variants, more efficient steps can be taken in early identification of the high risk carriers of the same next generation viruses.   SARS-CoV-2 Gene variant Gene polymorphism Disease severity 2022 12 01 337 346 http://tmuj.iautmu.ac.ir/article-1-1989-en.pdf 10.52547/iau.32.4.337

The production of reactive oxygen species is dependent of the intensity, duration and type of activity. Although the physiological amounts of reactive oxygen species are necessary to regulate cell reactions, their excessive production can cause numerous damages to the structure and function of cells and weaken physical function and endanger health. Although physical activity itself is a stimulus to increase the capacity of antioxidant defense, but in the case of intense and long exercises, the production of reactive oxygen species exceeds the capacity of antioxidant defense. In this situation, the use of exogenous antioxidant substances can be a good solution for the development of performance and physical health. Plants are abundant sources of antioxidant substances that can neutralize most active oxygen species caused by physical exercises, and then reduce inflammation and muscle damage induced by repeated muscle contractions, especially extrinsic contractions. Despite controversial findings due to differences in the methodologies of studies, their results generally confirm the effects of phytochemicals on reducing oxidative stress, inflammation, pain, muscle damage and improving physical performance. Based on these findings, it is recommended that people who undertake intense and long physical exercises should use plants containing phytochemicals in order to maintain and improve physical performance and develop health.   Intense physical activity Oxidative stress Inflammation Phytochemicals 2022 12 01 347 355 http://tmuj.iautmu.ac.ir/article-1-2011-en.pdf 10.52547/iau.32.4.347

Previous studies have pointed out its harmful effects on the male reproductive system. Therefore, in the present study, vitamin E and selenium were used to protect the testicles from the damage of this poison. Materials and methods: For this study, 42 adult male Wistar rats were prepared and divided into 6 groups as follows: Control group (without any additive substances); Cyper group (received cypermethrin by gavage at 30 mg/kg for 42 days); Cyper+Vit E group (received cypermethrin in the previous method and simultaneously receiving vitamin E at 100 mg/kg by gavage); Cyper+Se group (received cypermethrin in the mentioned method and simultaneously selenium at 0.5 mg/kg  by gavage); Cyper+Vit E+Se group (received cypermethrin, vitamin E and selenium by the above methods) and Vit E +Se group (received only vitamin E and selenium by the above mentioned methods). At the end of the course, the animals were weighed and then anesthetized to take blood to measure hormonal and oxidative stress parameters. Also, tissue slides at 5 microns thick were prepared and stained with H&E and Mallory's trichrome methods. Results: In the cypermethrin group, the body weight, as well as epididymal weights, testicular cell population, testosterone, LH, FSH levels and also antioxidant enzyme levels were decreased but MDA level was increased. Vitamin E or selenium administration alone could not reverse these changes, but combination of them could induce protection of testis, completely. Conclusion: The combination of vitamin E and selenium has a synergistic and protective effect against tissue and oxidative damage caused by cypermethrin in the rat’testis Cypermethrin Histology Selenium Testis Vitamin E. 2022 12 01 356 367 http://tmuj.iautmu.ac.ir/article-1-2009-en.pdf 10.52547/iau.32.4.356

However, the effect of residual amounts of these compounds on the physiological processes of the body has always been discussed. Materials and methods: In this experimental study, 27cucumber plants were sprayed with a concentration equal to twofold recommended dose (acetamiprid (50 g/l) and dichlorvos (4 ml/l)). After 24 hours, the residual amount was obtained and to evaluate the effect of these residues, 20 mice were divided into 4 groups. The control group and groups 1, 2 and 3 that received dichlorvos,  acetamiprid, and combination of two pesticides respectively in drinking water. Results: The residual pesticide in cucumber was obtained for acetamiprid 1.5 mg/kg and for dichlorvos 0.5 mg/kg. Their effect indicated a significant decrease in body weight and blood albumin levels (p<0.01) and an increase in liver enzymes (aspartate transaminase and alanine transaminase) and had changes in the number of testicular germ cells (p<0.05). Conclusion: Liver disorders and reduced reproductive potential in male mice can be attributed to the addition of pesticides to their drinking water. Monitoring programs to evaluate the presence of residual pesticides in food should be done continuously and special attention should be paid to the management of consumption of these pesticides.   Crops Chemical pesticides Liver Germ cells Laboratory mice 2022 12 01 368 378 http://tmuj.iautmu.ac.ir/article-1-2008-en.pdf 10.52547/iau.32.4.368

The aim of this study was to evaluate the effect of gallic acid (GA) on oxidative stress parameters and neuronal density in the brain hippocampus following RIR. Materials and methods: 48 male Wistar rats were randomly divided into 4 groups, including control, ischemia/reperfusion+normal saline (RIR+Saline), and ischemia/reperfusion+GA groups at doses of 100 mg/kg (RIR+GA100) and 200 mg/kg (RIR+GA200). Animals in all groups except control underwent unilateral nephrectomy (right). The treatments were performed for 14 days and then, the left kidney was ischemized for 45 minutes. After 72 hours, hippocampal activity levels of catalase (CAT), glutathione peroxidase (GPx), total antioxidant capacity (TAC) and malondialdehyde (MDA) were evaluated. Finally, neuronal density was measured in CA1 and CA3 regions of the hippocampus. Results: A significant decrease in CAT, GPx and TAC and an increase in MDA was observed in RIR + Saline group compared to the control group, which was associated with a significant decrease in neuronal density in CA1/CA3 (p<0.05). While in the GA-treated groups, along with a significant increase in CAT, GPx and TAC and a decrease in MDA in the hippocampus, showed a significant increase in neuronal density of CA1/CA3 regions compared to the RIR+Saline group (p˂0.05). Conclusion: GA pretreatment can ameliorate oxidative damage and neuronal death in the brain hippocampus of rats with RIR-induced acute renal damage.   Gallic acid Hippocampus Acute renal failure Rat 2022 12 01 379 388 http://tmuj.iautmu.ac.ir/article-1-2014-en.pdf 10.52547/iau.32.4.379

Hippocampus is a very sensitive tissue to cerebral ischemia. Propofol is an anesthesia that recently the use of this drug as a neuroprotective has been considered. In this study, the effect of propofol on CA2 and CA3 areas of the hippocampus following ischemia was investigated. Materials and methods: 24 Wistar rats were randomly divided into 4 groups, including: control ischemia, experimental and vehicle. The experimental group received 40 mg/ kg of propofol and the vehicle group received 1 ml normal saline 1 hour before ischemia intraperitoneally. The ischemic model was performed by bilateral closure of the common carotid arteries for 20 minutes then reperfusion was done. 4 days later, all rats were sacrificed and the hippocampal tissue was examined by Nissl staining method. Data were analyzed using SPSS-25 statistical software by one-way ANOVA and TUKEY test. p<0.05 was considered as Significant. Results: Ischemia/ reperfusion for 20 minutes caused degeneration of pyramidal cells in CA2 and CA3 hippocampus and these neurons showed a significant decrease compared to the control group, but propofol injection inhibited the decrease in the number of viable cells in these two areas. Conclusion: Propofol can be used as an effective agent in preventing or reducing the complications of stroke alone or with other drugs.   Propofol Hippocampus Ischemia/reperfusion Rat 2022 12 01 389 397 http://tmuj.iautmu.ac.ir/article-1-1925-en.pdf 10.52547/iau.32.4.389

Naseriniya69@gmail.com Hadi Smkhani Akbarinejhad hadiakbarinejhad@yahoo.com Background: In addition to physical problems, attention should also be paid to the psychological problems of patients with cardiac diseases. This study aimed to compare the efficacy of mindfulness-based cognitive therapy (MBCT) and short-term solution-focused therapy (SSFT) on psychological well-being and sense of mental coherence in patients with heart disease. Materials and methods: The method of this study was semi-experimental with pre-test, post-test and follow up with the control group. The population of this study consisted of all female students with heart disease studying in the second secondary school of Jolfa City in the academic year 2021-2022. In total, 45 female students were selected by purposive sampling method, who were randomly divided into three groups (Each group 15 people). Members of both experimental groups received their treatment, respectively, in 8 and 6 sessions of 1.5 hours; however, the control group did not receive any treatment. Measuring instruments were Ryff's psychological well-being (1980) and Flensberg's sense of coherence (2006) questionnaires. Analysis was done by repeated measures analysis of variance and Bonferroni post hoc test. Results: In the pre-test, mean and standard deviation of psychological well-being score and sense of mental coherence were not significantly different in the experimentals and control groups (p>0.05). Both treatments increased psychological well-being and sense of mental coherence in patient after the test, compared to the control group (p<0.001). In the follow-up phase, the effect of these two treatments was lasting (p<0.001). The effect of these two treatments on psychological well-being and sense of mental coherence at posttest and follow-up was not different (p>0.05). Conclusion: It seems that these two therapies can increase the acceptance of the disease in heart patients, so they can probably be considered as a useful treatment strategy to improve the mental status of heart patients Mindfulness Short-term Solution-focused therapy Psychological well-being Sense of mental coherenc Heart disease. 2022 12 01 398 408 http://tmuj.iautmu.ac.ir/article-1-1997-en.pdf 10.52547/iau.32.4.398
