. The purpose of this study was to investigate the comparison of the effectiveness of two methods of operational-skills and combined exercises training of immunity systems in male firefighters. 36 men firefighters were selected voluntarily. The participants of first experimental group were participated in one program of operational-skills training about eight weeks. This program was consisted of stair climb, equipment carry, victim rescue, ladder heel and raise, forcible entry, and hose drag. The treatment of the combined training program was included 15 minutes of aerobic running with 60 to 70 percent of maximum heart rate and five selected strength training for upper and lower parts of the body. Blood test was obtained with all the samples in fasted stated to determine the parameters of IL6, CD40 and cortisol before starting the training period and 48 hours after the last training sessions. The collected data were analyzed according to paired-samples t and analysis of variance with the significant level of P< 0.05. The collected data revealed that the level of cortisol and serum IL6 were decreased significantly in two experimental groups in comparison with the control group. But the level of soluble CD40 had significantly differences in the first experimental group in contrast with the other groups, and there were no differences between two other groups. the results of this study suggested that, it is better the male firefighters use operational- skills training to strengthen the immune system and reduce risk factors in cardiovascular disease

Cardiac rehabilitation program aimed at reducing secondary risk factors and improving function in patients undergoing coronary artery bypass grafting run which finally may delay or reduce mortality patients. A key component of this program is exercise. The aim of this study was to evaluate the effect of aquatic and dryland training on ABCG8 gene expression in middle-aged women’s peripheral blood mononuclear cells after coronary artery bypass grafting. 30 middle-aged women with cardiovascular disease were divided into three groups including control, aquatic and dryland resistance training. The program lasted for eight weeks of resistance training (3 sessions per week/ 60 minutes per session) and started with 60% of 1RM. Fasting blood samples were taken from all participants 48 hours both prior to the beginning of the training program and after the last training session. ABCG8 relative gene expression was detected by Real-time PCR method. Repeated measures and paired t-test with a significance level of p≤ 0.05 were used to determine differences between and within groups. Repeated measures test showed a significant increase in the relative ABCG8 gene expression in both the aquatic and dryland training groups (P= 0.001). Moreover, paired-samples t-test showed a significant difference in aquatic and dryland training groups regarding ABCG8 gene expression (P= 0.001; P= 0.001). It can be concluded that both training programs on land and water training, increase ABCG8 gene expression in middle-aged women after coronary artery bypass and a possible reverse cholesterol transport process can be improved.

Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease which is created by the accumulation of fat in the liver. Several studies have reported the prevalence of fatty liver in Iran, with different results. Our goal is to estimate the Overall prevalence of fatty liver in Iranian children and adolescents. We searched the national and international databases (PubMed ,Science Direct ,Scopus ,Web of Science),) Magiran,Iran Medex , and Scientific Information Database) With keyword " prevalence ", "Nonalcoholic fatty liver", "fatty liver", "children", "adolescents" and "Iran" from the years 1998-2017. The variance of each study was calculated by the binomial distribution formula. We used a random effect model to combine the prevalence rates reported in the studies. The STATA software (version 12) was used to analyze the data. Eight studies were identified with of a total of 6118 subjects. The pooled prevalence of NAFLD in both population (male and female) was 27.88% (95%CI: 18.7% to 37.02%) .In both populations there was marked heterogeneity between studies (I2 = 99.3%). There was evidence that prevalence was generally higher in males compared with females .   Our review suggests the prevalence of NAFLD in children and adolescent is high, particularly in those who are obese and in males.

The aim of this paper is to use a systematic review and meta-analysis to analyze the effectiveness of aerobic and resistance training on blood Flow mediated dilation In this study, flow mediated dilation was selected as valid index for vascular endothelial function. Search was done in databases PubMed, science direct, Scopus, Web of science, SID, Magiran and google Scholar with specified keywords among articles that were published in the years 1986 to 2016 both in Persian and English. After initial screening, full text search and critical appraisal, studies which pass the inclusion criteria were analyzed. From a total of 1562 articles that were analyzed, 23 received the study inclusion criteria for the systematic review. 14 study, which included 17 trials with meta-analysis inclusion criteria were analyzed. The results of the meta-analysis of studies showed that exercise can improve Flow mediated dilation in healthy subjects (SMD= 0/84, 95 % CI 0/55–1/13, p=0/001) and patients with coronary artery disease (SMD= 0/49, 95 % CI 0/30–0/68, p=0/001). Although the effect size obtained for different sports are different, but considering the low number of studies, we cannot make an absolute statement about the superiority of one method of training. The exercise can be effective in improving endothelial function, although still high-quality research studies with sufficient sample size is needed

Aerobic exercise is the most popular sport activity in cardiac rehab center for increase aerobic ability and decrease in fat mass of cardiovascular disease , the aim of this study was to investigate the effect of eight weeks aerobic exercise on LXR gene expression and lipid profile in middle aged men after CABG. The subjects were 20 CABG middle aged male patient were randomly assigned into two group : control (N=10), and aerobic training (n = 10) groups. Exercise group performed aerobic exercises for 8 weeks with an intensity 60% to 80% of heart rate. 48 hours before exercise and 48 hours after the last training session, all subjects blood samples were taken and plasma and monocyte isolation were performed to measure the indices. Data analysis were performed by using t-test and independent t-test, and non-parametric Mann-Whitney and Wilcoxon tests were performed at a significant level of p≤0.05. Significant increase in expression of LXR gene value and HDL and significant decrease in total cholestrole, apo A and B ratio, LDL,TGS in experimental group compared to the control group compared to the control group has seen. Improvement of lipid profiles levels and enhancing the expression of LXR gene after 8 weeks of aerobic exercises showed that Performing regular aerobic exercises as part of the cardiac rehabilitation can be effective in reducing the incidence of atherosclerosis and preventing recurrence of the patient

Mucopolysaccharidosis type I (MPS I) is a rare and highly progressive autosomal recessive, genetically-metabolic disorder that results of the mutation in the gene responsible for the production of Alpha-L-Iduronidase enzyme, which ultimately leads to destruction and cell death of tissues. The patient is asymptomatic at the time of birth, but few months after birth, symptoms gradually appear in the person's phenotype. Respiratory, skeletal, neurological, cardiac, gastrointestinal and ocular disorders are obvious in these patients. The purpose of this study is reporting a case of MPS I. Patient The patient is a 7 years old boy, repeatedly admitted to the Heshmatieh Hospital of Sabzevar University of Medical Sciences, due to a weak immune system, high fever, and complications of his MPS genetic disease. At 2.5 years old, MPS had been definitively diagnosed. In this patient, almost all symptoms of the Hurler syndrome including third tonsil, hepatomegaly, splenomegaly, large skull, large tongue, ocular corneal opacity, and the presence of yellow spots in sclera, spinal deviation, Umbilical hernia, hearing loss and the stenosis of the mitral valve was seen. Unfortunately, due to the lack of definitive treatment, only 20% of the patients have a chance of survival and recovery. MPS usually leads in death before the age of 20

 Background and goal : The attendance of humic acid in water resources is the main health problems of many Societies. There are various methods for decreasing or removing of humic acid. Of these absorbed is considered an effective method to remove it. SO Agriculture wastes were used for preparation of activated carbons by chemical activation using Ammonium chloride. In this study, the standard Merck carbon and carbon produced from plant waste used as adsorbents and adsorption experiments were performed in batc. Adsorption of humic acid (HA) on SAC and NAC as a function of solution initial pH (2-10), adsorbent dosage (0.1-1 g/L), contact time (5-50 min), concentration (5-20 mg/L), on the adsorption capacity, the two-parameter equilibrium models (Langmuir and Freundlich equations) were debated. The result showed that the pH effect at removal humic acid is an important parameter, and isotherm showed that the adsorption Followed of the Langmuir isotherm. Also it was found that the capacity of absorb can be markedly effected by carbon type. That it was 238, 294 , 250 mg/g For carbons Merck, Sycamore and steel respectively. Carbon prepared from Steel due to very high capacity could be effective for removal humic acid from aqueous solution

 

Knee valgus during dynamic activities can lead to anterior cruciate ligament (ACL) tear. The perpuse of this study was to investigate range of motion and isometric strength of ankle joint between gilrs who exhibit medial knee displacement during squat in compraed to control group.

This cross-sectional and descriptive study was carried out on forty healthy females (control, 20 ; dynamic knee valgus, 20) with no lower-extremity injury in the past 6 months elected randomly according to inclusion criteria. Peak isometric strength was measured in kilogeram using a hand-held dynamometer and active range of motion was measured in degrees with a goniometer. Independent t- test and Multi-variate analyses of variance were used to determine differences in strength and range of motion between groups (P≤0.05).

The reasults showed dynamic valgus group had the less dorsiflexion range of motion (P=0.000), increased eversion range of motion (P=0.024) and less plantarflexion strength (P=0.000) in compraed to control group.

According to present results interventions focusing on improving strength and range of motion of the ankle may improve kinematics during dynamic activities

Background and Purpose: Chronic neuropathic pain caused by damage or disturbance of the functioning of the somatosensory system are one of the major health problems and many people suffer from such diseases. The aim of this study was to investigate the effect of Umbelliprenin (UMB) on the symptoms of neuropathic pain in chronic constriction injury model (CCI) of neuropathy in adult male rats. 24Wistar rats (250±20g) were randomly divided into 3 groups: sham, CCI and CCI+UMB (100μg/rat) groups. UMB was injected intrathecaly one day before surgery, and 3 days after surgery. Von Frey and Hot-Plate tests were performed one day before surgery and on days 2, 4, 7, 10 and 14 after surgery. The results were reported as mean and SEM (P

Introduction and Postpartum depression is one of the important psychological problems of the mother during pregnancy and afterwards. The purpose of this study was to determine postpartum depression based on spouse intimacy and general self-efficacy in the first birth.

Because of the increasing resistance of pathogenic bacteria to common antibiotics, the new generation of researchers sought antimicrobial agents with plant origin as alternative medicine. Oregano is from Lamiaceae family and coriander is from Apiaceae family and has antimicrobial properties. This study aimed to investigate and compare the inhibitory effects of alcoholic extracts of coriander and oregano plants on Staphylococcus aureus, Klebsiella and Salmonella. 1000 ml of alcohol poured round-bottom flask, then the target plant (200-300 g of dried powder of plant) put into envelopes of filter paper and envelopes was placed in a distillation device. After 24-48 hours the obtained alcoholic extract was placed in the oven. DMSO was used to provide different concentrations of ethanol extract. The concentrations of 31/25 and 62/5 mg / ml of alcoholic extract of oregano and concentrations of 62.5 and 125 mg / ml coriander were able to inhibit and kill Staphylococcus aureus and weren`t able to inhibit and kill Salmonella and Klebsiella respectively . Although the clinical application of plant extracts and essences seems valuable due to fewer side effects compared to conventional therapeutic agents, in order to clinical application of plant extracts of oregano and coriander, more research about the mechanism of action of effective components of this plant on the microbial agents is needed.
