Objectives: The aim of this study was to evaluate the effect of 8 weeks of aerobic exercise on depression and sexual desire in middle-aged women diagnosed with depression. Materials and Methods: The present study is a quasi-experimental study. Sixty females volunteered to participate in this study and were randomly divided into 4 groups; group A was prescribed with antidepressant drug (n = 15), group B employed aerobic exercises (n = 15), group C combination of drug and aerobic exercise (n = 15) and group D which was the control group (n = 15), respectively. Beck Depression Inventory was used in these 4 groups to assess their level of depression and sexual functioning. For statistical analysis of the data the t test, one-way analysis of variance (ANOVA) and Bonferroni post hoc test was used. Results: Comparison within groups showed a significant decrease in the pre-test on depression variables of the 3 groups; the drug group (P = 0.006), exercise (P = 0.011) and combination (P = 0.001) and also, regarding the variable libido, significant increase in the pre-test and post-test was observed. Regarding the sexual desire variable, results showed that only the aerobic exercise group had a significant increase in the pre-test and the post-test (P = 0.005). Comparison of the group variables showed a significant difference between the 4 study groups in both variables of depression and sexual desire. Conclusion: Considering the effectiveness of exercise on depression, it is expected that aerobic exercise would be considered as an effective non-pharmacologic treatment with less side effect in reducing depression and increasing sexual desire. © 2017 The Author(s).

This paper illustrates how a generator profit may be affected by the pricing method of an oligopoly market model. Through utilizing a bilevel optimization technique and game theory concepts, Supply Function Equilibria (SFE) of pay-as-bid pricing (PABP) and marginal pricing (MP) mechanisms are derived. Theoretically, it is demonstrated that in the presence of strategic interaction, the generator optimal bidding strategy and the market clearing price are higher under PABP as compared with MP. In addition, the probability distribution patterns of expected loss and profit of each generator are constructed by simulating a multiperiod market under PABP and MP rules. It is shown that a generator has a higher expected loss or profit under PABP in unconstrained networks. However, the generator may gain less expected loss or profit if its physical location or transmission limitations are considered. © 2012 Elsevier Ltd. All rights reserved.

AIM: To compare genotype of Helicobacter pylori (H. pylori) isolated from saliva, dental plaques, gastric biopsy, and stool of each patient in order to evaluate the mode of transmission of H. pylori infection. METHODS: This cross-sectional descriptive study was performed on 300 antral gastric biopsy, saliva, dental plaque and stool samples which were obtained from patients undergoing upper gastrointestinal tract endoscopy referred to endoscopy centre of Hajar hospital of Shahrekord, Iran from March 2010 to February 2011. Initially, H. pylori strains were identified by rapid urease test (RUT) and polymerase chain reaction (PCR) were applied to determine the presence of H. pylori (ureC) and for genotyping of voculating cytotoxin gene A (vacA) and cytotoxin associated gene A (cagA) genes in each specimen. Finally the data were analyzed by using statistical formulas such as Chi-square and Fisher's exact tests to find any significant relationship between these genes and patient's diseases. P < 0.05 was considered statistically significant. RESULTS: Of 300 gastric biopsy samples, 77.66% were confirmed to be H. pylori positive by PCR assay while this bacterium were detected in 10.72% of saliva, 71.67% of stool samples. We were not able to find it in dental plaque specimens. The prevalence of H. pylori was 90.47% among patients with peptic ulcer disease (PUD), 80% among patients with gastric cancer, and 74.13% among patients with none ulcer dyspepsia (NUD) by PCR assay. The evaluation of vacA and cagA genes showed 6 differences between gastric biopsy and saliva specimens and 11 differences between gastric and stool specimens. 94.42% of H. pylori positive specimens were cagA positive and all samples had amplified band both for vacA s and m regions. There was significant relationship between vacA s1a/m1a and PUD diseases (P = 0.04), s2/m2 genotype and NUD diseases (P = 0.05). No statically significant relationship was found between cagA status with clinical outcomes and vacA genotypes (P = 0.65). The evaluation of vacA and cagA genes showed 6 differences between gastric biopsy and saliva specimens and 11 differences between gastric and stool specimens. CONCLUSION: Regard to high similarity in genotype of H. pylori isolates from saliva, stomach and stool, this study support the idea which fecal- oral is the main route of H. pylori transmission and oral cavity may serve as a reservoir for H. pylori, however, remarkable genotype diversity among stomach, saliva and stool samples showed that more than one H. pylori genotype may exist in a same patient. © 2012 Baishideng.

Rotavirus is the leading cause of acute gastroenteritis in worldwide young children. Effective vaccines to prevent rotavirus infection are currently available, although their clinical use is still limited, and rotavirus still causes many episodes of infantile gastroenteritis, mainly during the winter season. The aim of this study was to evaluate the prevalence of rotavirus infection in children aged<5-years-old who were hospitalised for gastroenteritis. One hundred and sixty-three stool samples from hospitalized children (<5-years-old) complicated with severe diarrhoea, in two hospitals in Jahrom City, Iran were collected from 2009 to 2010. Antigenic prevalence of rotavirus group A was distinguished by enzyme immunoassay. The antigen of group A rotavirus was diagnosed by EIA in 75 of 163 collected samples. The genotype of EIA-positive samples was determined by nested RT-PCR. The frequency of rotavirus genotypes G1, G2, G3, G4 and G9 was 17.33, 13.34, 2.67, 30.66 and 2.67%, respectively. Also, the frequency of mixed and non-typable genotypes was detected in 2.67 and 30.66%, respectively. G1/G8 mixed infection was the first of these rotavirus genotypes to be reported in Iran. Detection of high prevalence of group A rotavirus infection in hospitalised children with diarrhoea, and determination of circulating rotavirus genotypes in this region of Iran, provide useful data for formulating effective vaccines; especially for infants less than 5-years-old. © 2012 Indian Virological Society.

The Agromyzidae family includes the most important dipterous species miners of crops for agriculture. Knowledge of 2900 worldwide species are cited, of which about 7% are considered of agronomic interest. (Ortiza, 2009). All Agromyzidae species undermine the Internal tissue of different organs of plants. Depending on their eating habits they can be classified as leaf miners (leafmining), stem miners (stem-mining and tunneling), cambium miners, and parasites of flower buds or fruits. Agromyzidae genus within the Palaearctic region consists of 24 genera constituting a total of 1165 species. The first annotated list of Iranian leafminers of the family Agromyzidae (Diptera), comprising 26 species, is presented. Two Genera and four species, are considered to be new records from Iran: Amauromyza carlinae (Herring, 1944), Amauromyza fraxini (Beiger, 1980), Calycomyza humeralis (von Roser, 1840), Pseudonapomyza atra (Meigen, 1830).

Overweight, obesity, and diabetes are the most common disorders in the world. In most diets, carbohydrates are the greatest source of calories. Inhibition of carbohydrate digestion or absorption can decrease calorie intake to promote weight loss and combat obesity. It is also a mechanism for reducing hyperglycemia in diabetic subjects. Before being absorbed by the body, carbohydrates must be broken down into monosaccharides. α-Amylase catalyzes the hydrolysis of α-(1,4)-d-glycosidic linkages of starch and other glucose polymers. Inhibitors of this enzyme can be used in treatment of obesity and diabetes. In diabetic patients, inhibition of α-amylase leads to prohibition starch breaking and results in lower levels of blood glucose. The effects of pseudosaccharides, proteinaceous, and polyphenolic inhibitors have been previously reported. Polyphenolic compounds are widely distributed in plants and fruits and are present in normal diets. These compounds have been shown to possess beneficial effects in diabetes, cardiovascular diseases, atherosclerosis, allergy, inflammation, and osteoporosis. Among polyphenolic compounds, flavonoids are of particular significance: They have been shown to reduce cholesterol synthesis via direct action on HMG-CoA reductase and hydrolyze lipids via inhibition of phosphodiesterase (PDE) and diminution of cAMP breakdown. In recent years, many lines of research have been done on those plants which are being used traditionally as drug plants, and their effects have been surveyed on weight loss and control of blood glucose levels in diabetic patients. In this review, we want to investigate α-amylase inhibitors especially human pancreatic α-amylase (HPA) © 2014 Springer-Verlag London.

This paper presents a model for loading margin calculation integrated with transmission line switching. A mixed-integer nonlinear optimization model is developed which maximizes the loading margin of the system subject to various operational system constraints. An iterative algorithm, based on the Benders decomposition method, is used to solve the problem. The proposed method is tested on medium and large scale test systems and optimization results are compared with that of a non-decomposed method to show the efficacy of the proposed approach. © 2014 Elsevier Inc.

A power producer implementing nominal strategy can be penalized if not planning for randomness or will lose profit if protects its decisions against the most severe outcome. The robust optimization approach achieves a trade-off between these two extremes. This paper presents a robust method for deriving offers of a strategic generator under uncertainty. The problem is formulated as a bilevel mathematical program wherein the strategic generator, in the upper level, maximizes its profit subject to a transmission-constrained economic dispatch model in the lower-level. The randomness of input parameters in the lower-level problem involving rival offers and market demand, are modeled using uncertainty sets. The bilevel optimization model is then transformed into a mixed-integer linear optimization problem by deriving the robust counterpart of the lower-level problem and making use of a linearization-reformulation technique. Numerical results of several case studies are presented to illustrate the application of the proposed method. © 2014 Published by Elsevier Ltd.

Arial parts of 80 plants in eight populations of Teucrium polium growing in Khuzestan Province in the south of Iran were analyzed for quantitative and qualitative variation in essential oils and oil yield. The yields of essential oils ranged from 0.25 to 0.41% (w/w). Forty-three volatile compounds were identified by GC and GC-MS analysis. The sesquiterpene fraction constituted the main oil fraction of T. polium (75.6-82.6%) whereas monoterpene hydrocarbon (5.7-10.5%) occurred in smaller proportions. Major compounds with the mean relative amounts in eight populations were 11-acetoxyeudesman-4-α-ol (20.0%), α-bisabolol (17.8%), β-bisabolol (10.4%), (E)-caryophyllene (10.3%), caryophylleneoxide (4.5%), α-bisabololoxide B (4.1%) and β-pinene (3.1%). Comparison of the mean relative amounts of the essential oil components in a pair of populations located at different altitude in the same site showed a significant altitudinal effect on the variation of some essential oil components. In addition, comparisons based on the mean relative amount of the essential oil components between populations in different sites also showed significant differences among populations at different latitudes. In all four sites, the sesquiterpene/monoterpene ratio of the plants collected from the high altitude was higher compared with those collected from the low altitude. Principal components analysis based on the mean relative amounts of the essential oil components have led to the identification of four chemotypes. © 2014 Elsevier B.V.
