Introduction: Coffee is a diuretic plant, cause vascular expansion and reduce free radical oxygen. There is evidence that show its effects on kidney. Low dose of coffee reduces blood urea and cratinine but its overdose may lead to glomeruloschelrosis. In this study, the effect of high dose of coffee on rat kidney was evaluated by stereological method.
Materials and Methods: In an experimental study, 48 Sprgue-Dawley rats 230-250 gr were selected and divided randomly into 4 groups. The control group was fed with only tap water and the experimental groups were fed with different doses of aqueous extracts of coffee (0.25, 0.5, 0.125 gr/kg) twice daily. After 48 hours, the animals were deeply anesthetized and right kidneys were removed. The Sum slides were prepared and stained with Hematoxyline. Eosin. From each kidney, 15-17 glomeruli were selected and means of glumerular volume were estimated, according to Cavalieri principle and point counting methods.
Results: Our findings revealed that low dose of coffee extraction were led to increase in glomerular volume, but higher doses decreased these volumes. These results were significantly different form control group (p<0.05).
Conclusion: It seems that decrease in glomerular volume leads glomeruloschlorosis and reduction of glomerular filtration rate. However, there should be more investigation such as urea and cratinine measurement to calrify the exact mechanisms.

Background: The UN report on the 41% increase of cesarean labor and its risks in Iran in recent years on the one hand and its association with cognitive and psychological factors on the other motivated us to identify the involving variables so as to control unnecessary cesarean sections. The aim of this study was to investigate the role of fear of pain and related psychological variables (pain catastrophizing, catastrophic cognition, childbirth attitude, depression-anxiety-stress, and experience of pre-menstruation (PMS) in prediction of cesarean labor. Materials and Methods: In this cross-sectional study, 300 pregnant women from Atieh private and Shahid Akbar Abadi public Hospitals (150 participants from each) were selected and matched by variables, such as age, level of education, month of pregnancy, previous experience of deliveries, tendency to cesarean, type of hospital, and having PMS. To collect data, a battery of questionnaires, including fear of pain, pain catastrophising, catastrophic cognition, childbirth attitude, and depression-anxiety-stress (DASS) were used. The results were analyzed through correlation coefficient and logistic regression. Results: Education, previous experience of deliveries, month of pregnancy were not significant but such variables as the tendency to cesarean, type of hospital, and age were significant (P<0.05). Such variables as pain catastrophizing, catastrophic cognition, and childbirth attitude were significant but other variables, including fear of pain , depression-anxiety-stress, experience of PMS were not significant (P>0.05). Conclusion: Such variables as the experience of cesarean, type of hospital, and age as well as pain catastrophizing, childbirth attitude, and catastrophic cognition are significant variable in prediction of cesarean labor in pregnant women.

Background: Multiple sclerosis is a chronic and degenerative disease of the central nervous systemthat due to such reasons as its chronic nature, no prognosis, and absence of a definitive treatment causes stress in patients. Thus, this study was designed to examine the impact of peer educational program on stress in patients with multiple sclerosis in 2011. Materials and Methods: In this clinical trial, 110 patients with multiple sclerosis were randomly allocated to test and control groups (each group including 55 patients). After preparing 5 multiple sclerosis patients as the peer group, six training sessions forthe test group were held by the peer group over two months. Data collection tool was DASS 21 questionnaire that assessed patients’ stress before and after 4 months which was completed by both groups. In order to analyze the results, SPSS software 16 was used. Results: The results showed that before intervention, there was not astatistically significant difference between the two groups in stress score(p=0.24) while a statistically significant difference was seen between the two groups after intervention (p=0.001). Also, stress score in test group was statistically significant (p=0.001) but there was not a statistically significant difference between the stress scores of the patients in the control groups (p=0.39). Conclusion: Peer group educational program caused stress reduction in patients with multiple sclerosis. Hence, it is recommended that peer groups be used for education of multiple sclerosis.

Background: Nowadays, international concern about the impact of antibiotic residues on the environment increased and their removal has received a lot of consideration. The aim of this study was to investigate the efficiency of Fenton’s advanced oxidation process (H2O2/Fe+2) in sulfadiazine antibiotic removal from aqueous solutions. Materials and Methods: An experimental-laboratory scale study was done on a synthetic wastewater containing sulfadiazine antibiotic with 0.079, 0.19, and 0.47 mM concentrations under Fenton’s process. Then optimal values of affecting parameters, such as initial antibiotic concentration, molar ratio of reagents, [Fe+2] and [H2O2] concentration, detention time, and pH, were determined. The discharged effluent analyzed by HPLC-UV to identify the antibiotic residues. Results: The results showed that the optimal parameters in the Fenton’s oxidation process to remove the sulfadiazine included antibiotics at pH 3.5, molar ratio of [H2O2] / [Fe +2] equal to 1.5, and contact time of 15 minutes, respectively. In these optimal conditions, the efficiency of removal of antibiotic in concentrations of 0.079, 0.19, and 0.47 mM were 99.82%, 97.97% and 78.23% and the wastewater COD removal degrees were 83.33%, 78.57%, and 78.57%, respectively. Conclusion: The experiments showed the efficient removal of sulfadiazine antibiotic in wastewater by Fenton’s oxidation process. The efficiency of this method can also be considered in eliminating other antibiotics resistant to biological treatment

Background: 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.

Materials and methods: 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.

Results: 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.

Conclusion: 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.

  Background : 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.

  Materials and Methods: 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.

  Results: 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&le0.05), but differences in HECSI and VAS reduction between treatment and control group were not significant.

Conclusion: 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.

Background: Delayed muscular soreness after resistance exercises or eccentric trainings is probably because of muscle damage and injury. Nutrition by playing a crucial role in both protein synthesize and catabolism can influence the extent of muscle injury. The objective of this study was to assess the effect of single portion of Glutamine supplement consumption on injury indices of muscle after a session eccentric resistance exercise.

 Materials and Methods: This study used a randomized, double blind design that consisted of 80 volvnteer non-athletic males (aged 22.2±2.2 years, height 175±5 cm, weight 71.64±9 kg, body mass index 23.2±2.2 kg/m2, and body fat 17.5±2.4%). A total of 40 participants were divided randomly into 2 groups, supplement group (receiving 0.1 g/kg Body weight/day Glutamine) and placebo group (receiving 0.1 g/kg Body weight/day Maltodextrin). Serum keratine kinase (CK) was determined by photometric method, muscle pain and knee joint range of motion were measured using, respectively, a standard scale of PAS and goniometer before, 24 and 48 hours after a resistance test involving knee flexion.

Results: Glutamine supplement consumption caused no significant differences in CK levels reduction in none of the measured times, but it reduced the muscle pain at the times of 24 and 48 hours in comparison with the placebo group. In addition, the knee joint range of motion was significantly improved at 24 hours after the test.

Conclusion: It seems that this dose of Glutamine supplementation can reduce the apparent signs apart from muscle injury indices reduction.

Background and Aim: Proliferate potential differentiate into different cell lineages and high self-renewal of Mesenchymal Stem Cells (MSCs); thus, they are ideal tools for regenerative medicine. However, a leading problem is an oxidative stress in the target tissue and the apoptosis of transplanted stem cells before tissue repair. The pretreatment of stem cells with antioxidants may make them resistant to oxidative stress. Ginger is the main medicinal plant with antioxidant properties. This study explored the antioxidant effects of ginger extract on bioavailability and oxidative stress-induced apoptosis in human adipose tissue-derived mesenchymal stem cells and rat bone marrow examined. 
Methods & Materials: In this study, human adipose tissue-derived mesenchymal stem cells and rat bone marrow were cultured in a DMEM medium with 20% FBS. The explored cells were incubated for 4 and 6 hours for pretreatment with different concentrations of ginger extract (50, 100, 200, & 400 mg/mL); then, they were treated with 200 μM H2O2 for 2 hours. Bioavailability was analyzed by ELISA reader using an MTS kit and apoptosis was analyzed by flow cytometry using an Annexin V-FITC/PI kit into the manufacturer’s protocol at both times. The obtained data were analyzed by Analysis of Variance (ANOVA) using SPSS. 
Ethical Considerations: This study was approved by the Ethics Research Committee of Shahrekord Branch, Islamic Azad University (Code: IR.IAU.SHK.REC.1397.028).
Results: The MTS results indicated a dose- and time-dependent manner increase in the bioavailability of human adipose tissue-derived mesenchymal treated stem cells. Ginger extract treatment also dose- and time-dependently decreased the rate of apoptosis in rat bone marrow mesenchymal stem cells. 
Conclusion: Ginger extract, by reducing the oxidative stress in mesenchymal stem cells, elevates their lifespan in the target tissue, and increases the efficiency of these cells in tissue regeneration.

Background and Aim: This study aimed to investigate the effect of exercise timing on elevated postprandial glucose and after brief interval exercises in women with obesity.
Methods & Materials: Ten women with obesity (Mean±SD age = 40.41±3.97 years; weight = 86.66±7.26 kg; and BMI = 33.22±2.20 kg/m2) participated in a crossover design exercise intervention: 1) postprandial aerobic exercise, 2) pre-prandial aerobic exercise, 3) brief periodic exercise, and 4) control. Pre- and postprandial exercise included 30 min of moderate-intensity walking on the treadmill before and after each main meal (1 minute of exercise -30 seconds rest). The brief periodic exercise had three one-minute reps of activity every 30 min for 20 times during the day. Twelve-hour continuous glucose monitoring and two-hour postprandial glucose levels were calculated to examine changes in blood glucose levels.
Ethical Considerations: This study was approved by the institutional review board of the University of Isfahan (Ethics Code: IR.UI.REC.1397.119) and conducted in agreement with the ethical principles for biomedical research involving human subjects outlined in the declaration of Helsinki.
Results: The findings of this study suggested that brief periodic exercise resulted in a significant decrease in continuous glucose monitoring levels and postprandial glucose compared to the control group as well as pre-prandial exercise (P˂0.05). However, pre- and postprandial exercise did not result in significant changes in continuous glucose monitoring (P˃0.05). In addition, postprandial exercise led to a significant decrease in postprandial glucose compared to the control group (P˂0.05).
Conclusion: It seems that brief periodic exercise can have more beneficial effects on postprandial glucose levels, probably due to improved glucose metabolism in skeletal muscle.

Introduction: Breast cancer is one of the most common cancers and the principal cause of death in women. One of the mechanisms of cancer cells for the lack of access to the immune system is the production of compounds suppressing immune responses, such as interleukin-10. On the other hand, vascular endothelial growth factor, by binding to its receptors on the surface of endothelial cells, plays a significant role in vascular permeability and tumor vascularity. In this study, the expression of interleukin-10 and vascular endothelial growth factor in breast tumor tissue was investigated in an experimental tumor model.
Methods: First, mammary tumors were experimentally induced in Balb/C mice, and RNA was extracted from the tumor tissue. cDNA was synthesized from the extracted RNAs, and the expression level of 10-IL and VEGF genes was evaluated by RT-PCR.
Results: The results of data analysis showed that the expression of IL-10 and VEGF genes in the tumor tissue was higher than in the cells of the control group, but this increase in expression was not statistically significant.
Conclusions: In general, the expression level of Interleukin-10 and VEGF genes was increased in the experimental tumor model, but broader research and the correlation with other involved factors seem necessary.
