Interleukin-1β (IL-1β) as a cytokine act in relationship to development of obesity and Insulin resistance. purpose of the study was compare the effects of Ramadan fasting (as dietary pattern) and aerobic exercise training on IL-1β and Insulin resistance in non-active obese subjects. This study was semi-experimental research with repeated measures design. In this study، 18 obese male in Mashhad (between 40 to 50 years old and body mass index > 30 Kg/m2) randomly was selected and after it was divided into fasting (N=9) and fasting and aerobic exercise training (N=9) groups. While the first group performed the fasting، then other group was performed aerobic exercise training for 27 sessions. They also performed the fasting. Finally، blood samples were taken for four different times. Statistic analysis shown that body fat percent of subjects was significantly decreased in both groups (p<0/05). Also، amount of insulin resistance was significantly decreased in fasting group (p<0/05). In addition، amount of IL-1β was significantly decreased in both groups (p<0/05). Research results shown that levels of IL-1β decreased by fasting and especially by aerobic exercise training and it may lead to the decrease of insulin resistance in obese subjects.

Hand eczema (HE) is a common skin disease which often needs long term treatment.. There are several reports about the efficacy of topical doxepin in the treatment of pruritic dermal diseases. This study was undertaken to compare the efficacy and safety of 5% doxepin cream and clobetasol 0. 05% versus clobetasol 0. 05% alone in the treatment of hand eczema. a randomized double blind placebo-controlled، study was carried out during years of 2011-2012. In total 70 patients with moderate to severe hand dermatitis were selected randomly to be treated with either the doxepin 5% cream+ clobetasol or clobetasol + placebo twice daily for 8 days. Efficacy assessments were performed at baseline and 8days after termination of therapy، according to hand eczema severity index (HECSI) and visual analogue scale (VAS). Statistical analysis was done using SPSS software، version 18. 0 and statistical tests including paired T-test and independent T-test. Overall، 56 patients completed our study. Out of them 32 were male and 24 were female. The reduction of HECSI score and VAS was statistically significant in the treatment and placebo group (p≤0. 05)، but differences in HECSI and VAS reduction between treatment and control group were not significant. Although there is some evidence that doxepin 5% cream is effective in reducing the signs and symptoms of eczematous dermatitis، few trials have been performed. We suggest that in a more extensive clinical trial، the efficacy of this treatment against chronic hand dermatitis be evaluated.

Adenoidal hypertrophy is a common condition of childhood، when abstructive sleep apnea ocurs adenoidectomy is indicated. In less sever cases، non surgical interventions maybe considered، however few medical altematives are currently available. Intranasal steroids used to reduce nasal airway obstruction To assesthe effectiveness of intranasal corticosteroids for improving nasal airway obstruction and in children with adenoid hypertrophy. 77 children 1-12 years exhibiting adenoid hypertrophy symptom and confirmed with radiologic imaging and without tonsilar hypertropy that not inclined to surgery were included and divided two groups in one group were treatend with intranasal betanethason 3 times daily for 3 weeks and and second group treatend with intranasal NACL as placebo. The subjects were assessed for airway obstruction symptoms including، snoring mounth breathing and prulaunt rhinorea، via questionarre ear examination، first month and third month of treatment. Intranasal betanethasone improved airway obstruction symptoms especially night snoring but hadn’t effective on other symptoms and infection complications including rhinorea. Intranasal betanethasone can be used as alterative treatrnent for adenoidal hypertroply because its effect on airway obstruction symptoms due to probably reduction adenoideal size.

Patients with myocardial infarction are faced to multi stressors in which cause to increase their anxiety. This study with the goal of determination of the effect of Durosia Anethifolia (Barilax) on anxiety after myocardial infarction was accomplished.

This is a clinical trial which was done on 90 patients with MI. All people were selected by simple method at first and then they randomly allocated into two intervention and control groups. After 24 hours، perl of Barilax 1oo mg/ twice per day were prescribed for intervention group، and the same dosage of placebo were given to control group. Anxity rate 24 and 96 hours after MI by state Trait Anxiety Inventory (STAI) were measured. All data with X2 and paired T test were analysed.

The mean age of patients in intervention group was 60. 68 and 61. 46 in control group. In intervention group 51% male and 49% were female and in control group 71% were male and 29% were female. Before intervention، the mean of anxiety rate in intervention group was 46. 91 and in control group was 42. 24 with no significant difference. After intervention، the mean of anxiety rate in intervention group was 33. 35 and in control group was 36. 48 with significant difference (P= 0. 012).

Oral consumption of Durosia Anethifolia (Barilax) on anxiety rate after myocardial infarction was effective. So description of this drug as an effective drug on controling of anxiety after myocardial infarction is recommended.

Helicobacter pylori (H. pylori) is a gram negative bacilli that causes the stomach and duodenum diseases in human. An important virulence factor of H. pylori is a CagA gene that increases of colonization it in stomach epithelial cells and lead to inflammation and peptic ulcers. The aim of the present study was to production of recombinant protein containing highly antigenic region of CagA in E. coli.

In this experimental study، the antigenic region (1245 base pair) of CagA gene was detected by bioinformatics methods، proliferated by PCR method، digested by BamHI and XhoI restriction enzymes and cloned into pET32a plasmid and was expressed in the E. coli BL21 (DE3) pLysS with induced by IPTG. The expressed protein was purified with Ni-NTA kit and its antigenicity was studied by western blotting method.

Data showed the successful cloning and expression of the target gene. Recombinant CagA protein purified by Ni-NTA kit and dialysis with concentration of 1. 5 mg/ml. In western blotting، the produced protein was interacted with infected human and mice sera.

Results indicated that recombinant CagA protein (65 KDa) maintains its antigenicity، so could be used for serological diagnosis of H. pylori diseases and production of vaccine.

survey and control of nosocomial infections in the world is a global priority that The objective is to minimize infections in addition to decreased length of hospitalization And also significantly reduce the cost of health care. The aim of this study was evaluating the knowledge، self-efficacy and Practice of nursing staff in Disciplines Standard Precautions in order to prevention of nosocomial infection. This Cross-sectional and analytical study that was carried out on 130nursing staff selectedin in Arak university of medical sciense in 2013. Data collected with validity and reliebility questionnaire including of knowledge، self-efficacy and Practice of nursing staff in Disciplines Standard Precautions in order to prevention of nosocomial infection. Data was analyzed by using descriptive and analytical statistical methods and pearson correlation. The mean knowledge was 46. 92 ±14. 66 and Practice 49. 46 ± 6. 96 and average self-efficacy was 52. 2: ±10. 81 about infection prevention. There was not significant relationship between knowledge and Practice. But there was a significant relationship between self-efficacy، knowledge and Practice and marriage. Moreover there was a significant relationship between knowledge and gender. (p<0. 05). Despite moderate self-efficacy majority of Nurses do not have appropriate knowledge about prevention of nosocomial infection based on the findings of this study. Considering the important role of nurses in nosocomial infection prevention، training is necessary to increase nurses prevention behaviors. Therefor paying more attention by authorities to apply the necessary actions for training of nurses.

SLC26A4 gene mutations are the second currently identifiable genetic cause of autosomal recessive non syndromic hearing loss (ARNSHL) after GJB2 mutations. In databases، several potential STR markers related to this region have been introduced. In this investigation، the identity and informativeness of D7S2459 CA repeat STR marker in SLC26A4 gene region was examined in five ethnic groups of the Iranian population. The research study was accomplished by genotyping the locus in 165 individuals of five different ethnic groups including Fars، Azari، Torkaman، Gilak and Arab using polymerase chain reaction (PCR) followed by polyacrylamide gel electrophoresis (PAGE) and fluorescent capillary electrophoresis. In this study، results were analyzed by GeneMarker HID Human STR Identity software، GenePop program and Microsatellite Tools software. Analysis of the allelic frequency revealed the presence of 8 alleles for D7S2459 marker in the Iranian population. Among all، allele 148bp at the D7S2459 locus with 31% frequency was the most frequent. The Azari ethnic with 84. 8% observed heterozygosity was the highest among all ethnic groups. Finally، analysis of PIC value revealed that D7S2459 marker could be considered as a highly informative marker in each ethnic of the Iranian population (PIC value above 0. 7). Our data suggested that D7S2459 could be introduced as a highly informative marker in molecular diagnosis of SLC26A4 based ARNSHL by Linkage analysis.

Balance is one of the basic needs for daily activities. It has an important role in static and dynamic activities. The purpose of this study is to evaluate the balance of people with peripheral neuropathy after 4-weeks of functional and balance exercise program. In this quasi-experimental study، 22 diabetic patients with diabetic peripheral neuropathy (experimental group، n=11; control group، n=11) with the mean age of 53. 79 years، mean height of 163. 41cm، and mean weight of 71. 49 kg، were randomly selected. Berg and T. G. U. G tests were used to evaluate the balance of patients. 12 sessions of combined training (balance and functional training) were used as intervention program. A paired t test was used for the differences of pre-post test and independent t-tests were used to compare the experimental and control groups. The paired sample t-test showed that training program has significant effect on functional and dynamic balance. The comparison between the two groups showed no significant deference between pre-functional balance tests and significant post-functional balance test after training program. Patients with diabetic neuropathy may have an impaired balance. The most important reason is the damage of proprioceptive receptors as combined training (balance and functional training) may improve balance and blood circulation in this organ also putting extra load on the visual system، vestibular and proprioceptive stimulation system and improves balance. Hence، it can be recommended as exercises to improve balance.

Human brain consists of two hemispheres with contralateral control of the body. One hemisphere''s function is predominate to another، so one side of the body is more powerful in performing special tasks comparing the other which this property is almost used to determine predominant hemisphere of the brain. This analytic study performed to assess the effect of handedness and gender on the result of school readiness assessment examination in children. Of 6 to 6. 5- year-old children living in middle socioeconomic regions of Qazvin city، referred to preschool Examining center to assess educational readiness and other physical examination، 400 children equally of both sexes were randomly selected in two Left-Handed (LH) and Right-Handed (RH) groups to compare the results of school readiness assessment examination. The data was statistically analysed and P-Value less than 0. 05 was considered significant. the results of School Readiness Assessment Examination in LH and RH children were 38. 71 ± 2. 70 and 38. 15 ± 4. 04، respectively without significant difference. These results were 38. 8 ± 3. 8 and 38. 30 ± 3. 4 in boys and girls respectively، without significant difference. Comparing RH and LH cases in each sex group did not show any significance. No significance was observed comparing the results of School Readiness Assessment Examination in LH and RH groups and between two gender groups.

Factor XIII deficiency is an extremely rare، autosomal recessive coagulation disorder with estimated prevalence of 1/2000000 worldwide. This disorder represents with different clinical manifestations including، umbilical cord bleeding، recurrent abortion and CNS bleeding. CNS bleeding is a common but life threating complication of disease. The aim of this study was to evaluate the effect of a common polymorphism of thrombin activatable fibrinolysis inhibitor (TAFI) occurrence of CNS bleeding in patients with severe factor XIII deficiency. This case control study was performed on 34 patients with factor XIII deficiency and history of CNS bleeding and 36 patients with factor XIII deficiency but without CNS bleeding as control group. Initially all patients were molecularly analyzed for factor XIII deficiency، then both groups were assessed for common TAFI Thr325Ile polymorphism. Finally obtained data was analyzed by SPSS software. Molecular analysis of TAFI Thr325Ile polymorphism revealed that almost all patients with CNS bleeding (89%) had this mutation that in 67% of patients was homozygote. There is a significant relationship between Thr325Ile polymorphism in homozygote manner with incidence of CNS bleeding in factor XIII deficient (OR 18/9، 95% CI 3/8 to 95/1). It seems that Thr325Ile polymorphism is a suitable prognostic factor in patients with severe factor XIII deficiency and this probably polymorphism increases risk of CNS bleeding about 20 fold.
