  Background & objectives : CXCL5, also known as epithelial cell-derived neutrophil-activating peptide (ENA-78), is a chemokine that has a role in some diseases. CXCL5 blocks insulin signaling by activating the Jak2/STAT5/SOCS2 pathway. It is reported the association between -156G>C (rs352046) polymorphism in the promoter region and diabetes. The aim of this study was to examine whether there is an association between this polymorphism and diabetes mellitus in Ardabil province population.

  Methods : A total of 100 patients affected diabetes were recruited from Ardabil province population 100 healthy control subjects also were recruited from the same area. The region containing the CXCL5 - 156G>C polymorphism was genotyped by PCR amplification and restriction fragment length polymorphism analysis, and allele frequency data were analyzed using Fisher test.

  Results : The results show a higher frequency of carrying both the G/G and G/C genotype in patients with diabetes compared with healthy controls (p-value=0.01 and 0.006, respectively). In addition, the frequency of allele C was significantly increased (p-value = 0.028) in patients with diabetes (25.5%) compared with controls (12%).

  Conclusions : Our findings suggest a role of CXCL5 in the pathogenesis of diabetes. Also, replications in other populations with larger sample sizes are required to confirm these findings.

  Background and Objectives : The risk of coronary artery disease increases with increasing of blood pressureboth in hypertensive and normotensive persons on the other hand nutritional factors have asignificant effect on blood pressure. The purpose of this study was to assess theeffect of caffeine on blood pressure in sedentary healthy male during resistance exercise.

  Methods: In single-blind crossover study , twenty healthy and non-athlete male in the University of Mohaghegh Ardabili randomly selected and stratified according to age and BMI into twogroups: caffeine and placebo. The subjects performed repetitions to exhaustion at 60% of 1RM for any motion of chest press, leg press, squat and lat pulldown, 1 hour after taking caffeine (6 mg/kg body weight) or Placebo (similar dosage of starch). Blood pressure (BP) was measured before and 1 hour after taking caffeine and also immediately after any exercise. Data analysis was conducted using independent and paired t-test.

  Results : Results indicated that systolic and diastolic BP and mean arterial pressure significantly elevated following caffeine intake at rest, but no significant differences were observed after exercise.

  Conclusion: These findings indicate that caffeine at this dosage level alters cardiovascular dynamics by augmenting arterial blood pressure in moderately non-athletes male at rest. However, it seems that taking caffeine before resistance exercise does not cause abnormal elevations in blood pressure in sedentary healthy male.

Background & objectives: Epilepsy is a chronic neurological disorder that disrupts normal brain activity due to abnormal electrical discharge of brain cells. Mood swings, depression and anxiety are the common complications in epilepsy. The aim of the present study was to compare alexithymia in patients with Tonic-clonic epilepsy, Juvenile Myoclonic Epilepsy (JME), and healthy individuals.
Methods: In this casual-comparative study, sampling was performed by convenience sampling method. The study population consisted of all epileptic patients and the study sample included 134 participants (N= 74 Patients and N= 60 healthy people) individuals aged 18-35 years. Among the patients, 14 were excluded due to lack of selection criteria and 60 samples (N= 29 with myoclonic and N= 31 with Tonic-clonic epilepsy) remained.
Data regarding alexithymia was gathered by Toronto Alexithymia Scale, and analyzed by ANOVA, Scheffé post - hoc test and t-test were performed for independent groups.
Results: Findings showed that the mean of Alexithymia in those with JME,  tonic-clonic epilepsy and normal individuals were 64.44, 61.41, and 54.24, respectively. The difference between the two groups with myoclonic and tonic-clonic epilepsy was not statistically significant. However, there was a significant difference found between those with tonic-clonic epilepsy and normal individuals (T= 6.82; p<0.01). In addition, patients with  JME  and tonic-clonic epilepsy had more difficulty in identifying and describing emotions, and external thought direction compared to normal ones, while no such a difference was observed between the two groups with epilepsy.
Conclusion: Epilepsy is accompanied by reduced processing of emotional information such as alexithymia. Individuals with tonic-clonic and juvenile myoclonic epilepsy are less qualified for recognizing and describing emotional information, and their intellectual orientation is mostly external. Also, since the location of discharge in both types is widespread and similar, no significant difference in alexithymia was observed between the patients with tonic-clonic and myoclonic epilepsy

Background & objectives: Fenugreek (Trigonella foenum-graecum) is one of the most ancient and well-known medicinal plants, and its useful role has been well - established in treating of many diseases. The purpose of this study was to investigate the effect of Fenugreek on spermatogenesis, total antioxidant capacity and malondialdehyde (MDA) level in male diabetic rats.
Methods: In this experimental study, 24 male Wistar rats weighing approximately 200±20 gram were used. The rats were randomly divided into 4 groups of six. group1: control group, Group2: diabetic, Group3: diabetic+Fenugreek (8gram /kg diet), group4: diabetic+Fenugreek (2gram /kg diet). This treatment continued for 4 weeks. Blood glucose, total antioxidant capacity, malondialdehyde, and sperm profiles were determined.
Results: Blood glucose in diabetic rats which received Fenugreek significantly reduced compared with diabetic animals. Fenugreek also reduced body weight and MDA level of semen (p<0.05).On the other hand, Fenugreek increased the total antioxidant capacity of semen (p<0.05) and normalized sperm profiles (p<0.05).
Conclusion: According to the present results, it can be concluded that consumption of Fenugreek extract probably reduced MDA level, body weight, and normalized sperm profile thus, Fenugreek extract can be used to treat sexual dysfunction in males.
