Introduction: Infertility is an emotional crisis with physical, economic and psychosocial challenges, because it interferes with all personal life aspects. This event is a sever tension of life and produces strong emotional shock in the infertile couple. This study is done with the aim of comparison the psychiatric problems of infertile men and women referring to infertility clinic of Hamadan Fatemyeh Hospital. Materials and Methods: This is a cross-sectional analytical study. Sample size was 400 infertile men and women which were selected by convenience sampling. Data was collected by a demographic questionnaire and SCL90, and analyzed through descriptive statistics and independent T test. Results: Our study indicates that infertile women experience mental problem significantly more than men. With p<0.05 infertile women in 9 categorize of SCL90 including depression, anxiety, phobia, psychosomatic, interpersonal sensitivity, hostility, paranoid ideation and psychotics are significantly different from infertile men. Conclusion: It seems women experience more stress in personal, social and sexual life and women are more sensitive to infertility phenomena that probably is due to cultural problems, mental susceptibility and/or special forms of social communication

Background: Peripheral neuropathy is a common complication associated with diabetes mellitus. It has been shown that oxidative stress is an important etiological factor in neuropathy which contributes to its development however, the exact pathophysiology underlying this complication is not fully understood. This study was designed to examine the effect of regular exercise and vitamin C administration on pain threshold in rats. Materials and Methods: In this experimental study, 36 male Wistar rats (220±10 g) were allocated to control and diabetic (control, vitamin C, exercise, and exercise+ vitamin C) groups. Diabetes was induced by the subcutaneous administration of streptozotocin (60 mg/kg). A week after the induction of diabetes, the rats were subjected to swimming training and vitamin C treatment for 8 weeks. At the end of weeks 3, 5, and 8, Tail-Flick test was done on the rats to assess pain threshold. Data were analyzed using SPSS software. Results: Diabetes significantly decreased pain threshold in the rats. Diabetes-induced hyperalgesia was significantly decreased by training and vitamin C. Concurrent effects of training and vitamin C on thermal pain threshold were significantly higher than each of them alone. Conclusion: Regular exercise together with vitamin C administration can be a proper method for preventing thermal hyperalgesia associated with diabetes. Therefore, they can be effective in the treatment and management of pain

Background: Paraoxonase1 activity shows decline in patients with coronary artery disease. The C to T change in the -107 position of promoter is the most important genetic determinant of serum levels of paraoxonase 1. Study of this polymorphism and its relationship with the type of fatty acid composition of phospholipids in HDL particles can be found in the common pursuit of better medicines and considered in drug treatment.

Materials and Methods: In this descriptive study 265 Patients were selected and divided in two groups based on LDL level (131 in case and 134 in control). Information of subjects were collected from questionnaire and the results of biochemistry and molecular tests. Fatty acids of HDL phospholipids were measured with Gas chromatography technic .

Results: PON1aryl esterase activity, had no significant changes after treatment with lovastatin but paraoxonase activity had more significant increases in the CC genitype of -C/T107 polymorphism. Percent of oleic acid, linoleic acid and icosapentanioc acid in HDL phospholipids were increased by lovastatin.

Conclusion: Treatment with lovastatin in the CC genotype is probably more protective effect against cardiovascular disease. Following treatment, in patients with higher paraoxanase 1 activity Oleic acid and linoleic acid have also increased in HDL phospholipids.

Abstract

Background: Diabetes mellitus is associated with reductions in fertility indices. Resistance training, on the other hand, through reducing the adverse effects of diabetes, exerts a positive impact on diabetic individuals. The aim of the present study was to examine the effects of ten weeks of resistance training on serum levels of reproductive hormones and sperm parameters in Wistar rats with diabetes mellitus type 2.

Materials and Methods: In this experimental study, 36 Wistar rats with mean weight of 200±50 were randomly assigned to healthy control, diabetic control and diabetic training groups. The diabetic resistance training group received ten weeks of resistance training (climbing up the ladder) following the induction of diabetes. Twenty-four hours after the last training session, left epididymis of the rats was examined for studying sperm parameters and blood serum samples were examined for evaluating reproductive hormones. Data were analyzed using one-way ANOVA and Turkey’s Post Hoc test at 0.05%.

Results: Ten weeks of resistance training induced significant increases in serum testosterone and FSH levels in the resistance training group in comparison to the diabetic group (p<0.007).Resistance training did not have any significant effects on serum LH levels in the resistance training group compared to the diabetic control group. In addition, sperm parameters (sperm count, survival rate and motility) presented significant improvements compared to the diabetic group(p<0.05).

Conclusion: Resistance training can improve sperm parameters, including sperm count, survival rate and motility, through increasing serum testosterone, LH and FSH levels (reproductive hormones) in rats with diabetes mellitus type 2.

Abstract

Background: The aim of this study was to investigate the effect of aerobic exercise and GnRH agonist on the levels of apelin and insulin resistance index in girls with central precocious puberty.

Materials and Methods: In this study, twenty-five girls (7.44±0.34 years) with precocious puberty were included. They were randomly divided into three groups (drug, n=10, exercise+drug, n=8, and exercise, n=7) and one control group (healthy, n=10). In the experimental group, aerobic exercise for 12 weeks, 3 days/week was done, duration intensity of exercise gradually increased 5 minutes and 5% respectively every 2 week. Also, the GnRH agonists were used as medicine. BMI, the apelin and insulin resistance index were assessed before and after exercise.

Results: Insulin resistance index and apelin serum levels in experimental group (exercise and exercise+ drug) were significantly decreased(p=0.05), while these factors were unchanged in control group (p=0.05). Additionally, BMI in exercie groups was significantly decreased (p=0.000), while it was increased in experimental group (drug group) (p=0.06).

Conclusion: Considering to current data, it could demonstrate that aerobic training and GNRH agonists at the same time can lead to a decrease in BMI and apelin and an improvement in insulin resistance index.

Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized societies. As an appetite inhibitory and energy balance regulator, nesfatin-1 plays a substantial role in the pathogenesis of obesity-related abnormalities. This study was conducted to determine the effects of 12 weeks of combined training (resistance training and high-intensity interval training (HIIT)) on the serum levels of nesfatin-1 and some liver enzymes in men with NAFLD.
Methods: In this semi-experimental study, 20 middle-aged men with NAFLD were randomly divided into two exercise and control groups. The exercise program included 12 weeks of combined training, featuring two sessions per week of resistance training and one session of HIIT. Body weight, body mass index (BMI), nesfatin-1 peptide, liver enzymes (ALT, AST, and ALP), lipid profile, maximal oxygen consumption (VO₂max), and body fat percentage at the beginning and after 12-weeks were evaluated. Independent and dependent t-tests were analyzed to assess intra-group and inter-group differences, and the significance level was
P < 0.05.
Results: 12 weeks of combined resistance training and HIIT increased nesfatin-1 and decreased liver enzymes ALT, AST, and ALP in the exercise group compared to the control group and the pre-training stage (P < 0.05). We also observed an increase in VO₂ max and a decrease in body weight, BMI, body fat percentage, and LDL in the exercise group compared to before starting the training protocol (P < 0.05).
Conclusions: Based on the results of the present study, it can be concluded that performing combined exercise training for twelve weeks led to an increase in nesfatin-1 peptide levels and a decrease in liver enzymes. It was suggested that this could be a cost-effective therapeutic approach recommended for patients with NAFLD.

Introduction: The thickness of the molecular and pyramidal layers in the hippocampus represents a pivotal aspect of Alzheimer's research. This study was conducted to investigate the effect of swimming endurance, resistance, and combined exercises on the molecular and pyramidal layers of the hippocampus tissue thickness of Alzheimer's rats.
Methods: In this experimental study, 40 large white Wistar laboratory rats (6 weeks old; Weight 180-200 g) were randomly and equally divided into five groups: healthy control, Alzheimer's control, endurance, resistance, and combined. Alzheimer's disease was induced by intraperitoneal injection of trimethyltin chloride (8 mg/kg). Two weeks after the injection and confirmation of Alzheimer's induction, the training protocols of endurance (5-sessions/week, the first to the fourth week incrementally from 5-15-min to 45-min of swimming, the fifth to the twelfth week 60-min of swimming), resistance (5-sessions/week, The first week of familiarization with the exercise, week 2; 30%, week3-5; 70-90%, week6-8; 100-110%, week9-10; 120-130%, and week11-12; 140-150% of body weight), combined (2 resistance sessions/week and three endurance sessions/week) was performed for 12 weeks. Forty-eight hours post-intervention, animals were dissected, and hippocampus tissue was harvested. Finally, the data were analyzed at the significance level of P < 0.05.
Results: The thickness of the molecular and pyramidal layers of the hippocampal tissue of Alzheimer's animals decreased compared to healthy animals, and all three endurance, resistance, and combined exercise protocols increased layers (P < 0.001). However, the increase in the molecular and pyramidal layers thickness of the hippocampal tissue of combined group rats compared to the endurance and resistance group had a greater increase (P < 0.01).
Conclusions: These findings highlight the changes in the thickness of the hippocampal tissue layers concerning Alzheimer's pathology and the effect of combined exercises on this parameter. While exercise may have positively affected hippocampal volume and synaptic plasticity, more research is needed to fully understand the impact of exercise on hippocampal layer thickness in Alzheimer's.

Introduction: Being overweight is associated with increased cortisol secretion, along with heightened anxiety and depression. This study aimed to compare the effect of six weeks of concurrent moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) with HIIT training alone on body composition, plasma cortisol levels, and anxiety and depression levels in overweight male students.
Methods: In this semi-experimental research, 27 overweight students were selected and randomly divided into three groups 9: MICT+HIIT concurrent training, HIIT training, and a control group. The MICT )15 minutes of exercise per day at 60-65% of maximum heart rate with an additional 5 minutes every two weeks). The HIIT (3 minutes of running at 70-75% of maximum heart rate, followed by 3 minutes of active rest at 50% of maximum heart rate, with three repetitions in the first two weeks, four repetitions in the second two weeks, and five repetitions in the final two weeks).
Results: Both types of training protocols resulted in reductions in weight, body mass index, cholesterol, low-density lipoprotein, cortisol levels, anxiety, depression, and an increase in high-density lipoprotein (P < 0.05). There was no significant difference between the two types of exercise in terms of effectiveness on these variables; however, only peak oxygen consumption and triglycerides were associated with better changes in the MICT+HIIT group.
Conclusions: For overweight male adolescents aiming for weight loss and improved mental health, HIIT alone is sufficient, and adding MICT does not provide additional clinical benefits.
