Abstract
Background & Objective: Respiratory tract infections causes 4.5 million children death in the world annually that occur mostly in developing countries like Iran. Bacterial and viral pathogens are responsible for this event and Adenovirus is one of the major responsible agents. According to multiple survey, incidence of viral pathogens in different world region is different so local survey is needed to describe regional incidence of different viral pathogens. Rapid test for detection of respiratory pathogens help us to select appropriate treatment and avoidence of antibiotic overusage. So abuse the aim of this study was to evaluate incidence and clinical presentation of Adenovirus infection in children in Tehran with rapid test. Methods:This study is a descriptive-cross sectional analysis. All 3 month to 15 year old children with upper respiratory tract infection that come to OPD of Rasol-e-Acram Hospital in one year(1385) are included. Direct smear of patient’s throat was evaluated by rapid chromatography test for adenovirus infection. SPSS software was used to analyse the data. Results: 160 children with upper respiratory tract infection with a mean age of 61.5 months were evaluated. 57.5% were boys and 42.5% were girls. 77.4% had fever, 66% had sore throat, 37.4% had cough, 27% pharyngeal exudate, 16.4% had abdominal pain, 15.7% had vomiting, 13.8% had cervical lymphadenopathy, 10% had diarrhea, 5.7% had petechea in palate and 1.9% had conjectivitis. They admitted 24% in spring, 14.1% in summer, 23.1% in fall and 38.5% in winter. Adenovirus infection was detected in 10(6.3%) cases, 4(40%) boys and 6(60%) girls with mean age of 83.7(SD=58.5). they were detcted 20% in spring, 30% in summer, 30% in fall and 20% in winter. Conclusion: Adenoviruses are responsible in 6.3% of upper respiratory infections in children. They become less prevalent with increasing age. Its prevalence did not obey seasonal pattern. Fever and sore throat are most common clinical signs and cervical lymphadenopathy is more prevalent in adenovirus infection than others.

Abstract
Background & Objectives: Postpartum depression is one of the most important problems during post partum. Several new medications have been introduced for treatment, but considering their side effects and also breast feeding women's desire for dietary complements rather than chemical drugs, this research was done to determine comparison of effectiveness of Omega-3 fatty acids with placebo in treatment of mild to moderate postpartum depression. Methods: This double-blind randomized placebo controlled trial study was done on 120 women with postpartum depression, who had the required criteria. First by using Edinburgh Postnatal Depression Scale (EPDS) in women who gave birth 2 weeks to 3 months before, postpartum depression approved for determining the severity of depression, Beck Depression Inventory scale (BDI) was used. Women with mild to moderate depression who had a score 46 on the (BDI) and did not have any tendency to use anti-depressant drugs under the supervision of the psychiatrist, enrolled in the study and randomly assigned to receive either 1gr of Omega-3 capsules or placebo for 8 weeks. Severity of depression was measured before treatment and weekly during treatment in both groups. The data analyzed through T-Test, repeated measurements of one way ANOVA and chi square test in SPSS 14/Win. Results: There were no significant differences between two groups with respect to demographic characteristics. Results show that Mean Depression Scores before treatment in Omega-3 group (35.4 ± 9.2) decreased after treatment (17.7 ± 7.0), which was significant (p<0.0005). Mean Depression Scores before treatment in placebo group (34.2 ± 3.4) decreased after treatment (33.6 ± 9.3) which wasn't significant (p=0.57). There was a significant difference between reductions of Depression Scores in two groups(P<0.001). Conclusion: According to research results, use of Omega-3 1gr/day for 8 weeks improves postpartum depression.

Abstract
Background & Objectives: Nowadays, appearance of ESBL producing bacteria is medical problem in the treatment of infections. Uropathogenic Escherichia coli like many other bacteria can produce these types of enzymes. T he assessment of the ESBL production by clinical isolates is not done routinely in laboratories. The aim of this study was to determine the prevalence of ESBL producing E.coli and its antibiotic resistance pattern in Kermanshah. Methods: This cross - sectional study was done on 200 Uropathogenic E. coli strains isolated from people in Kermanshah. Sensitivity of isolates to different antibiotics was determined by disk diffusion test and ESBL production was assessed by DDST method. Results: The E. coli strains showed high susceptibility to imipenem (100%), amikacin (97%), nitrofurantoin (95.5%), gentamicin (85%), cefepime (75%), ceftazidime (74%), ofloxacin (73.5%), ciprofloxacin, ceftriaxone and aztreonam (71%) and cefotaxime (70%) respectively. The highest resistance was seen to ampicillin (77%), carbenicillin (76%), pipracillin (74%) and SXT (62.5% ). Resistance rate to third generation cephalosporins was 63-75%. Fifty seven isolates (27%) were ESBL producers and 47 isolates (87%) produced all four types of ESBL enzymes. Conclusion: There are some similarities and differences in the antibiotic resistance pattern and ESBL production among the isolates in different areas of Iran and other countries. Identification of ESBL producing bacteria and determining its antimicrobial resistance pattern are recommended to effective treatment of infections.

Abstract
Background & Objectives: Excess body fat percentage is one of the risk factors in the progression of chronic diseases. Anthropometric indices of obesity are screening tools to determine subjects at risk of cardiovascular disease all over the world. The aim of this study was to investigate the relationship between abdominal obesity and the early stage of atherosclerosis by Carotid Intima- Media Thickness (CIMT) on women . Methods: This cross-sectional study involved 100 healthy women aged 18–50 year. Anthropometric indices were measured and calculated according to standard protocol. Cut off points for waist circumference (WC), waist to hip ratio (WHR) and waist to height ratio (WHtR) were 88 cm, 0.8 and 0.5 respectively Carotid Intima- Media Thickness was determined by using non-invasive ultrasound as an indicator of early stage of atherosclerosis. Subjects with mean CIMT≤0.8 mm and CIMT>0.8 mm were considered as "normal subjects" and "subjects at risk", respectively. Results: Average age of subjects was 30.96±8.1 and the mean of WC, WHR, WHtR and CIMT were 95±0.17, 0.87±0.08, 0.61±0.11 and 0.63±0.15, respectively. All abdominal anthropometric indices significantly associated with mean CIMT. Waist circumference with cut off point of 88 Cm had sum of sensitivity and specificity higher than WHR and WHtR. Conclusion: Waist circumference index with cut off point of 88 cm is better than WHR and WHtR to identify subjects at high risk of atherosclerosis.

Abstract
Background & objectives: Diabetes mellitus is one of the prevalent metabolic disorders in the world and mostly it is related to Obesity. Central obesity results in higher risk of diabetes, cardiovascular disease and hyperinsulinemia. Hyperinsulinemia is the main reason of central obesity disorders. Studies have been shown that the fruits, vegetables and drinks are rich in phenolic and antioxidants components may alleviate diabetes diseases. One of these fruits is pomegranate that is rich in flavonoids. Therefore, this study was designed to determine the effect of unsweetened pomegranate juice consumption on insulin resistance, inflammatory factor and anthropometric measures in diabetic patients. Methods : In this clinical trial, 50 patients with type 2 diabetes aged 30-50 years were recruited into the study and randomly assigned into two groups: (1) intervention group (n=25) who drank 240 ml unsweetened pomegranate juice daily and (2) control group (n=25) who drank 240 ml water daily for two months. Fasting blood glucose, inflammatory factors including hs-CRP, anthropometric measures including weight, height, waist and hip circumference, BMI were determined at the baseline and after 8 weeks. Nutritionist IV program, Independent sample t-test, Paired sample t-test were used for data analyses. Results : Comparison of fasting blood glucose, HbA1C, body mass index, hs-CRP between the two groups before intervention did not reveal a significant difference. The result of the study showed a significant decrease in insulin resistance, body weight, hip circumstance, waist circumstance in intervention group ( p <0.05 ، p <0.01 ، p <0.05 ، p <0.05 respectively) w hereas no significant changes were found for serum glucose, HbA1C, hs-CRP in this group . Conclusion : These findings indicate the beneficial effect of the daily consumption of unsweetened pomegranate juice on insulin resistance, body weight, waist and hip circumstances.

Abstract
Background & Objectives: The development of technology has naturally given rise to an increase in environmental low-frequency electromagnetic fields and consequently has attracted scholars' attention. Most of the studies have focused on transmission lines and power system distribution with 50 Hz. This research is an attempt to show the effect of 50 Hz magnetic fields on bioelectric parameters and indicates the possible influence of this change in F1 cells of Helix aspersa . Methods: The present research used Helix aspersa neuron F1 to identify the location of magnetic fields as well as the rate of effects of environmental magnetic fields on nervous system. Control group was used to study the effect of elapsed time, electrode entering and the cell membrane rupture. Intuition group and environmental group were considered in order to study the potential impact of interfering environmental factors and identify the effectiveness rate of magnetic fields, respectively. For the purpose of producing uniform magnetic field Helmholtz coil was used. Electrophysiological recording was realized under the requirements of current clamp. And, in order to show the impacts from magnetic fields on ion channels Hodgkin-Huxley cell model was applied. All data were analyzed taking the advantage of SPSS 16 software and two-way ANOVA statistical test. P < 0.05 was considered as significance level. And MATLAB software environment and PSO were used in order for applying the algorithm and estimating the parameters. Result: No statistically significant difference was found between control and sham groups in different time intervals. Once the 45.87 microtesla was applied significant differences were observed 12 minutes after the application. The highest amount of change happened 14 minutes after the application of more fields. With the application of the field, the amplitude of the sodium action potential shows decreasing trend . No significant changes were observed in different time intervals, whereas significant differences were seen in frequency of action potential during different time intervals. The amplitude of AHP shows no significant changes . Conclusion: The results indicated that low-frequency magnetic fields with 50 Hz frequency will directly lead to change in bioelectric activities of neurons through a change in amount and rate of opening and closing of ionic channels and the conductivity of sodium and potassium channels reduces together with increase in conductance of potassium dependent calcium channel (AHP).

Abstract
Background & objectives: Due to the increasing prevalence of bacterial resistance, there is a growing attention to application of auxiliary treatment of pharyngitis. The aim of this study was to investigate the effect of honey throat spray in the auxiliary treatment of patients with a diagnosis of pharyngitis.
Methods: At the start, different physicochemical quality parameters of the honey sample were evaluated. Then, the bottles of honey and the placebo throat spray were prepared. The numbers of 70 patients with the diagnosis of pharyngitis were included in a one-step and double-blinded study. In addition to standard treatment, each patient received either one of the honey or placebo throat spray. The clinical symptoms of the patients were compared between the two groups at baseline and then at 24 hours, 48 hours, 5 days and 10 days after the starting the treatment procedure.
Results: As per results, the quality of honey sample was met to the standard honey criteria. The treatment and placebo groups were statistically similar in terms of demographic specifications or clinical symptoms at the time to enter the study. Pharyngitis recovery was better in treatment group than in the placebo group; this positive effect was statistically significant for symptoms of morning phlegm and painful swallowing, 24 hours after the starting treatment. In treatment group, after 48 hours, symptoms of fever and painful swallowing were resolved, while this indicator was 23% in placebo group. Also, throat pain of 85.71% of patients in treatment group and 17.14% of patients in placebo group was relieved. Overall, the mean recovery time in treatment group was shorter than placebo group.
Conclusion: The findings of this study showed that the use of honey throat spray as auxiliary treatment of pharyngitis can improve the clinical symptoms of pharyngitis and reduce recovery time.

Abstract
Background & objectives: Over the last couple of decades, research has focused on attempting to understand the genetic influence on sports performance. Whole exome sequencing (WES) has great potential to explore all possible genetic variants associated with physical performance. However, this new technique has not been used in sports genetics research. Therefore the aim of this case study was to report new variants in genes involved in skeletal muscles strength (ACE, NOS3, IGF1R, IL-6) in an elite weightlifter using WES.
Methods: After obtaining a written testimony from a 32-year-old man, who is a member of the Iranian national weightlifting team, 5 cc of blood was taken and then DNA was extracted. DNA samples were analyzed using the whole exome sequencing method.
Results: Whole exome sequencing analysis revealed a missense variant (99454613G>A) in IGF1R, 22771156C>T polymorphism in IL-6, 150695726T>C and 150704250C>G polymorphisms in NOS3 and 61573761T>C and 61564052A>G in ACE genes.
Conclusion: Results of whole exome sequencing analysis revealed a missense variant and polymorphism in muscle strength and hypertrophy related genes in this elite weightlifter. However, other studies with larger sample sizes are needed to investigate the relationship between these variants and power athlete status.
