Abstract
Background: Primary dysmenorrhea is one of the most common complaints in women's medicine, in the absence of any pelvic pathological failure. Exercise is commonly reported as a factor to decrease dysmenorrhea symptoms. One of the new therapeutic methods is “Kinesio Taping” which claimed to be able to reduce pain, swelling and muscle spasms. Thus, this study tries to determine and compare the effectiveness of using two therapeutic methods of stretching exercises and taping in painful menstruation of high school students.
Materials and Methods: This study is an operational, quasi-experimental and two- stage study with a control group and pre-test and post-test design. Thirty female high school students with the average age of 16.8±0.99 were selected as available, and were divided into three groups, randomly. For the first group, stretching exercises were carried out and the second group was taped with Kinesio Tape and control group did not any exercise. Mood Disorder Questionnaire (MDQ) was used to collect information. Visual Analogue Scale (VAS) and schober test were used for measuring the level of pain and range of motion, respectively. Data analysis was performed by a repeated measures ANOVA at the significant level of p>0.05.
Results: There was a significant improvement in back and abdomen pain and back range of motion.On the other hand, comparing data after intervention showed a significant difference in pain intensity between two groups. But, no significant difference was notified in increased back range of motion in group with kinesion tape.
Conclusion: Kinesio Taping has better effects than stretching exercises in reducing tesucing pain. Too, Stretching exercise has better effects in increasing back rang of motion.

Abstract
Background: Wound healing is a complex process that is impaired in diabetic patients due to several factors. So far, the positive effects of mesenchymal stem cells secretions in wound healing process have been reported. In this study, we investigated the effect of human mesenchymal stem cells Conditioned media on expression of effective factors involved in wound healing.
Materials and Methods: 27 rats were divided into 5 groups: no wound control, normal control, diabetic control, diabetic placebo and diabetic experimental. Diabetes was induced by Alloxan. A wound was created on the back of the rats. Then, the conditioned medium was prepared from mesenchymal stem cells. Diabetic experimental rats received 200 microliter of conditioned medium intravenously. The wounds were sampled and expression of KGF and TGF-&beta1 genes was examined by RT-PCR on days four and seven after wounding.
Results: In the diabetic experimental group, expression of KGF gene at fourth and seventh days had been non-significantly increased in comparison to diabetic control group. While, expression of TGF-&beta1 gene in diabetic experimental group compared to diabetic control group had been significantly (p<0.05) increased on fourth day, and non-significantly increased on seventh day.
Conclusion: It seems that using the conditioned medium derived from human mesenchymal stem cells positively affects the expression of trophic and inflammatory factors involved in diabetic skin wound healing.

Abstract
Background: Staphylococcus aureus is one of the important pathogens can cause infections in hospitals specially in intensive care units (ICU). It seems that nasal carriage is important risk factor for developing l infection at ICU units. This study was designed to investigate the frequency of S. aureus nasal carriage and its virulence in patients admitted to ICU units in Vali-Asr hospital at Arak university of medical sciences.
Materials and Methods: In this cross-sectional study, nasal swab samples were obtained from all the patients hospitalized in ICU unit of Vali-Asr hospital from July-December 2014 at admission. After identification, methicillin resistance and the frequency of pvl and acme genes determined by PCR. Demographic data were collected using questionnaire and were analysed using SPSS 20 software.
Results: Out of 390 patients, 81(20.8%) and 31(12.9) patients had been colonized with MSSA and MRSA, respectively. The result of culture was negative for 278 patients (71.3%). 77.4% of MRSA and 54.3% of MSSA isolates were positive for acme gene. Also, 11.11% of and 6.45% of MSSA MRSA isolates were positive for pvl gene.
Conclusion: The application of medical supportive devices like cv line, ventilator, history of surgery operation and antibiotic use significantly was associated with S. aureus nasal carriage. High prevalence of S.aureus shows that these bacteria settled in the hospital. Hence, infection control measures must be performed to reduce the risk of hospital infection.

Abstract
Background and Aim Chronic Lymphocytic Leukemia (CLL) is the most commonly occurring leukemia in adults, accounting for about 30-25% of total leukemia. One of the important etiological causes of this leukemia is the disruption of the Nuclear Factor Kappa B (NF-kB) signaling pathway. The two proteins of Apoptosis-Inducing Ligand (APRIL) and B-Cell Activating Factor (BAFF) play a role in the pathogenesis of this leukemia by affecting the NF-kB signaling pathway. In this study, due to the effect of miRNAs in regulating many cellular processes, the prediction of the prominent miRNAs targeting APRIL and BAFF transcripts in B-cell CLL patients was evaluated using specific and different bioinformatics programs.
Methods & Materials Afterwards retrieving the sequences of APRIL and BAFF proteins from the NCBI website, by using several programs including miRanda, TargetScan, miRWalk, DIANA and miRDB with different algorithms, the prediction of miRNAs targeting these genes was investigated.
Ethical Considerations This study was approved by the Research Ethics Committee of Arak University of Medical Sciences.
Results Based on the scoring system of bioinformatics programs, “hsa-miR-145-5p” and “hsa-miR-185-5p” were identified as miRNAs targeting APRIL gene, while “hsa-miR-424” and “hsa-miR-497”were miRNAs targeting BAFF gene. They were suggested for the practical studies in future.
Conclusion Based on the important role of APRIL and BAFF genes in the normal process of cell death and B-cell evolution, it seems that the mi-RNAs predicted by bioinformatics programs using different algorithms can be used as a diagnostic molecular biomarker to identify B-cell CLL patients.

Introduction: Insomnia and sleep disorders are related to a decrease in physical and mental health and quality of life. The purpose of this study was to investigate the effect of sleep deprivation on blood sugar, cortisol and insulin levels in athletes compared to non-athletes.
Methods: In this semi-experimental study, 14 healthy men participated in two groups of athletes (7 people) and non-athletes (7 people). One night of sleeplessness (8 hours) was applied to the subjects of both groups. According to the objectives of the research, blood samples were taken from all the subjects in two stages. The data were analyzed using the dependent t test for intra-group comparison and independent t test for inter-group comparison at a significance level of 5%. In conducting the research, the principles of the Declaration of Helsinki, the general guidelines for ethics in research with human subjects and the regulations governing it were observed and the code of ethics was issued by the ethics committee of Lorestan University.
Findings: Insomnia did not lead to a significant difference between the blood sugar and insulin levels of athletes and non-athletes when faced with a (p≤0.05). Also, insomnia did not cause a significant difference in the amount of cortisol between two groups of athletes and non-athletes (p≤0.05). Conclusion: It seems that changes in blood sugar, cortisol and insulin are related to the duration of insomnia and are not affected in short-term and intermittent insomnia.
Keywords: Insomnia, blood sugar, cortisol, insulin, athlete, non-athlete

Abstract
Backgrand: Inflammation can cause damage to the central nervous system, leading to neuropathological diseases such as stroke, pain, schizophrenia, and Alzheimers. AIM2 is a member of the PYHIN hematopoietic nuclear protein family that binds to cytosolic DNA and activates caspase-1, one of the inflammatory-mediated caspases that activates pro-inflammatory cytokines. The aim of this research is to investigate the effect of a swimming training course on the expression of caspase-1 and AIM2 proteins in the hippocampus of male Wistar rats.
Method: The statistical population of this study included 16 male Wistar rats (6 weeks) divided into two groups: a group without training and an endurance training group. Eight rats were placed in each group. The group without training did not engage in any sports activities, while the training group participated in a swimming training session. After a 4-day familiarization period, the rats swam for 30 minutes from the fifth day. Independent T-test was used to evaluate the interventions, and all statistical calculations were done using SPSS statistical software.
Results: The results of this research showed that exercise caused a significant decrease in the level of caspase-1 and AIM2 proteins in the hippocampus of male Wistar rats.
Discussion: Overall, this study suggests that endurance swimming training can effectively reduce caspase-1 and AIM2 proteins. Therefore, it is possible that exercise, by reducing inflammatory factors, can be a potential treatment for diseases caused by inflammation, such as sclerosis, diabetes, cancer, and Alzheimers.

Abstract
Introduction: Resistance training (RT) is an important part of athletes' preparation exercises with the aim of strengthening physical fitness, creating neuro-muscular adaptations and improving sports performance. The aim of this study was to investigate the effect of resistance training with weight on NCV of tibial and peroneal nerves, muscle strength, agility, flexibility and performance of half-back, half-turn and angel balance skills in seven- to ten-year-old gymnasts.
Methods: In this semi-experimental study, 24 children with two years of experience in gymnastics (age: 8.5±1.5 years, weight: 32.10±9.40 kg, height: 135±13 cm) voluntarily Participated. Subjects were randomly divided into two groups including gymnastics training and gymnastics training + resistance training with weights. And they trained for 10 weeks. During the research, one group did general gymnastics exercises, and the other group did resistance training with weights three times a week in addition to gymnastics exercises. Before and after the exercises, NCV test, Sargent's jump muscle power tests, agility of 9x4m back-and-forth run, Wells' flexibility, and performing half-back, half-turn and balance skills of Angel were performed. Independent t-test was used to analyze the data. And a significance level of P<0.05 was considered.
Results: The results showed that the NCV in the tibial and peroneal nerves increased significantly in the weight resistance training group compared to the general gymnastics training group. Also, muscle strength in Sargent's jump, agility in 4x9m back and forth running, and the performance of half-back and half-turn skills increased significantly (P<0.05). However, no significant change was observed in the flexibility with the Wells test (P=0.870) and execution of Angel's balance skill (P=0.552).
conclusion: 10 weeks of resistance training with weights significantly increases neuromuscular adaptations, NCV, muscle power, agility, and implementation of half-back and half-varus skills in gymnast children. Therefore, it is suggested to use resistance exercises with weights to improve the performance of children athletes in the field of gymnastics and fields where nerve conduction speed, muscle power and agility are effective in the success of athletes.

Abstract
Introduction: Physical activity positively influences various physiological factors, laying the groundwork for beneficial changes. Myostatin and follistatin are among these factors, whose levels are influenced by gender and physical activity. The present study was conducted with the aim of investigating the effect of traditional resistance training (RT) and high functional training (HIFT) on the serum levels of myostatin and follistatin in young women.
Methods: In this semi-experimental study, 30 young women were selected and divided into three groups: intense functional training, traditional resistance training, and control. Blood was drawn 24 hours before and 48 hours after the end of the interventions to measure the serum levels of myostatin and follistatin. The exercise protocols were performed for eight weeks, 3 days a week and 60 minutes a day. Ultimately, the collected data were analyzed using the ANOVA statistical method, with a significance level set at P < 0.05.
Results: The results showed that follistatin level was significantly higher in the RT and HIFT groups than in the control group (P = 0.001). Also, the amount of follistatin in the HIFT group was considerably higher than the RT group (P = 0.01). The results showed that the level of myostatin in the RT and HIFT groups was significantly lower than the control group (P = 0.001). Also, the amount of this factor in the HIFT group was substantially lower than in the RT group (P = 0.01).
Conclusions: In general, the findings of the present study show that performing intense resistance and functional exercises causes a favorable change in the expression of physiological factors related to muscle growth in women. It seems that the effect of intense functional exercises is greater than resistance exercises.
