Yellow mosaic disease in grain legumes in Indian subcontinent is caused by two important virus species viz. Mungbean yellow mosaic virus (MYMV) and Mungbean yellow mosaic India virus (MYMIV), belonging to the genus Begomovirus of the family Geminiviridae. The genomic components of a begomovirus causing yellow mosaic disease in blackgram in southern India were cloned and sequenced. Nucleotide sequence comparison of DNA A component shows the virus isolate to be a variant of Mungbean yellow mosaic virus:-(MYMV-[IN:Vam:05]). However, DNA B component of the present virus isolate has greater similarity (92%) to Mungbean yellow mosaic India virus. Agroinoculations of the viral clones produced typical yellow mosaic symptoms in blackgram and mungbean, severe leaf curl and stunting in French bean, similar to blackgram isolate of MYMIV. Blackgram isolates of both the virus species were only mildly infectious on cowpea, produced atypical leaf curl symptoms and not yellow or golden mosaic. In agroinoculations done by exchanging genomic components, symptom expression was seen only in French bean. In cowpea, blackgram and mungbean there was no visible symptoms though viral DNA could be detected by PCR. © 2011 Springer Science+Business Media, LLC.

Nickel-alumina nano-composite coatings were obtained from nickel sulphamate solution containing nano-α-alumina particles by direct current (DC) plating. Nano-alumina particles were dispersed in the solution with the aid of different concentrations (50-300 mg l -1) of the anionic surfactant sodium dodecyl sulfate (SDS) by ultrasonic method. The microhardness variation of the coatings in different concentrations of SDS was investigated. Furthermore, the corrosion behavior of composite coatings was studied by polarization measurements in 3.5% w/v NaCl solution. The results revealed that increasing the surfactant concentration, up to an optimum value (125 mg l -1), led to more uniform distribution of nano-particles in the coatings, improved corrosion potential (E corr) to the most positive value (-0.209 V) and corrosion current density (i corr) to the lowest value (1.141 × -7 A cm -2), and enhanced the microhardness of composite coatings to 492 HV. However, beyond this optimum level, these properties were attenuated. © 2012 Elsevier B.V. All rights reserved.

The current study examines the protective effect of oxytocin (OT) on cardiomyocyte apoptosis modulated by mitochondrial ATP-dependent potassium (mitoKATP) channel and permeability transition pore (mPTP) in the preconditioned myocardium of anesthetized rats. Eighty rats were equally divided into eight groups. The hearts of all animals except for the sham group were subjected to 25 min ischemia and 120 min reperfusion. Oxytocin, 5-hydroxydeconoate (5-HD), a specific inhibitor of the mitoKATP channel, and atractyloside (ATRC), an mPTP opener, were used prior to ischemia. Hemodynamic parameters were recorded throughout the experiment. Evaluations were made by infarct size, plasma lactate dehydrogenase level (LDH), transmission electron microscopy (TEM) and immunohistochemistry studies. OT prevented mean arterial pressure drop during early phase of ischemia and reperfusion. Treatment with OT before IR induction normalizes cardiomyocytes both in light microscopy and TEM observations. In addition, OT significantly reduced TUNEL- and increased Bcl-2-labeled positive cell number relative to IR (p < 0.05). However, 5HD or ATRC inhibited the protective effects of OT on cardiomyocytes damaged by IR (p < 0.05). Ultrastructural changes including extensive myofibril loss, sarcolemmal disruption and mitochondrial swelling due to amorphous dens bodies indicate necrosis induction in 5HD and ATRC as well as in IR groups. Restoration of immunohistochemistry parameters and protection against IR-induced ultrastructural changes confirm OT cardioprotective effects via mitoKATP channel and mPTP modulation in apoptosis induced by ischemia-reperfusion. © 2012 Elsevier Inc.

This study examined the applicability of the natural zeolite for simultaneous removal of ammonia and humic acid, two of the most encountered concurrent contaminants in the surface waters. The influence of various operating parameters including pH (2-10), concentrations of zeolite (1-10. g/L), initial concentration of ammonia (10-100. mg/L) and/or humic acid (2-20. mg/L), contact time (5-90. min), and temperature (20-50 °C) was investigated on the removal of target contaminants from water through different experimental runs. The results indicated that zeolite had best performance for simultaneous removal of ammonia and humic acid at the pH close to that of natural waters. The adsorption of humic acid was found to be improved in the presence of ammonia. The removal of ammonia and humic acid as single or binary components using natural zeolite was indicated to be a rapid process, following the pseudo-second-order kinetic model. The temperature positively influenced the removal of target contaminant both as single and binary components, although with greater influence for lower concentrations of zeolite. Equilibrium adsorption of ammonia and humic acid onto natural zeolite had best fitness with the Freundlich isotherm at all temperatures ranging from 20 to 50 °C. The maximum experimental adsorption capacities of ammonia and humic acid as binary components were 49.7 and 10.5. mg/g, respectively. It was understood from the results of this study that adsorption onto natural zeolite is an efficient in performance, simple to operate, and economical process and thereby affordable technology for simultaneous removal of ammonia and humic acid from the contaminated water source. © 2011 Elsevier B.V.

Introduction: Regarding chronic nature of epilepsy and its side effects and to access the effective treatment procedures, herbal medicine has received remarkable interest. The aim of this study was to determine the anticonvulsant effects of hydro-alcoholic extract of Anethum graveolens seed on pentylenetetrazol (PTZ) -induced seizure in male mice. Methods: Fifty-six albino male mice were divided randomly into seven groups including the negative control (saline), positive control (Phenobarbital) and treatment groups using different doses of hydro-alcoholic extract of Anethum graveolens seed (50, 100, 300, 500 and 1000 mg/ kg). To provoke convulsion, PTZ was injected to all groups and initiation time of myoclonic and tonic-clonic seizures as well as surveillance after 24 h were measured. Results: The results indicated that hydro-alcoholic extract of Anethum graveolens seed (AGS) delayed the initiation time of myoclonic and tonic-clonic seizures in comparison with saline group. The latency was considerable for myoclonic and tonic-clonic seizures at all above mentioned doses of AGS extract except for the lowest one. Moreover, the protective effect of AGS extract against mortality was statistically significant at all doses except for 50 mg/kg. Discussion: As the hydro-alcoholic extract of AGS showed an appropriate response in experimental model of convulsion, it might be considered as an adjuvant therapy with other traditional antiepileptic medications.

Coriander (Coriandrum sativum L.) has been cultivated for a many years in different parts of Iran. The chemical profiles of different accessions were analysed by means of GC-MS. The essential oil content of the dried seeds varied from 0.1% to 0.36%. Thirty-four different compounds were identified in the essential oil of all accessions. Linalool (40.9-79.9%), neryl acetate (2.3-14.2%), γ-terpinene (0.1-13.6%) and α-pinene (1.2-7.1%) were identified as main components in the oil of the coriander accessions. Almost all of the studied accessions contained more that 60% linalool, showing the high quality of coriander seeds produced in Iran and the suitability of the accessions as initial genetic materials for the breeding of homogenous and talented Coriander cultivars. © 2010 Taylor & Francis.

Background: Systematic reviews favor a better body image and sexual activity in patients who have undergone conservative breast surgery (BCS) compared to modified radical mastectomy (MRM). In those patients with the same survival, MRM remains the surgical choice among both surgeons and patients in Iran as well as in many other countries. This cross-sectional study focuses on health-related quality of life in early stage breast cancer patients following BCS and MRM. Methods: From all post-op patients who referred to the Motahari Clinic, Shiraz, Iran, we used a convenient sampling method to select 160 MRM patients and 127 who underwent BCS. Translated copies of the EORTC QLQ-C30 (version 3) and the EORTC QLQ-BR23 questionnaires, in addition to a third questionnaire which was customized and prepared for this study, were completed by the patients under our supervision Results: The two groups were compared by a multivariate method (Hotelling's trace test) after controlling for variables with unequal values such as disease stage, hormonal and radiotherapy treatments, and patients' role in the choice of surgery. We noted a significant difference (P < 0.001) attributed to a significantly better BI in the BCS group (average: 78.49 ± 23.14) compared to the MRM group (average: 60.71 ± 23.14). Discussion: We concluded that in terms of body image, BCS has a better impact on health-related quality of life.

Vesicoureteral reflux (VUR) is a risk factor for kidney scarring, hypertension and declining renal function. Standard diagnostic methods are invasive and can cause exposure to radiation and urinary tract infections (UTIs). We aimed to investigate urine albumin and interleukin-8 levels as markers of ongoing VUR and renal damage in children without UTIs. Random urine samples were collected from 51 children, including 16 children with VUR (group A), 17 children with resolved VUR (group B) and 18 normal children (group C). The diagnosis of VUR or resolved VUR was confirmed by voiding cystourethrogram (VCUG) or direct radionuclide cystography (DRNC). All children had normal kidney function and had no evidence of UTI in the preceding three months. Random urine specimens were assayed for albumin (Alb), creatinine (Cr) and interleukin-8 (IL-8) and mean values were compared by one way ANOVA. In groups A and B, the mean age at first UTI was 31.7 ± 2.4 and 27 ± 2.0 months respectively. In group A, the mean duration between VUR diagnosis and study entrance was 30 ± 9.1 months. In group B, the mean duration between VUR diagnosis and recovery was 19.9 ± 1.3 months. Overall, 76.4% of affected children had bilateral VUR and 41.2% had severe VUR. There were no significant differences in urinary Alb, IL-8, Alb/Cr and IL-8/Cr between the three groups. The current study does not support the hypothesis that microalbuminuria or urinary IL-8 are good indicators of ongoing VUR and renal injury in children.

This paper presents a novel control approach of a current source inverter drive system using an induction motor. A variant of hysteresis-band current control adapted to the current source inverter circuit topology is proposed. The current control strategy is based on the correction of the two out of three larger errors of the instantaneous real currents of motor with respect to their references. The well known GTO current source inverter in which an auxiliary branch of inverter is added in order to ensure the continuity of DC link current in special conditions The indirect rotor flux-orientated vector control of induction motor gives the reference motor's currents. In order to suppress the inherent instability of current fed induction motor, a coefficient of derivative of real motor's currents is added to the reference ones. The simulation results of steady state and dynamic operations of the novel control asynchronous drive are shown and the advantages of this technique are discussed. © 2010 IEEE.

The Gail model has been widely used to quantify an individual woman's risk of developing breast cancer by using important clinical parameters, usually for clinical counselling purposes or to determine eligibility for mammography and genetic tests. The aim of the present study was to estimate the five-year and lifetime breast cancer risk among women in Rasht, Iran. In this cross-sectional study, 314 women were evaluated at Alzahra Women Hospital in 2007. Participants were ≥35 years of age without a history of breast cancer. Risk estimation was performed using the computerized Gail model. A five-year risk &1.66% was considered high-risk; 5.1% of women were high-risk. The mean five-year breast cancer risk was 0.8% (SD±1). Mean breast cancer risk up to the age of 90 years (lifetime risk) was 9.0% (SD±3.9%); 16.2% of the participants had a five-year risk higher than the average woman of the same age, and 18.2% had the same risk. Also for the lifetime risk, 11.1% of the women had higher risk and 1.6% had the same risk as the average woman. Routine use of the Gail model is recommended for identifying women at high average risk for increasing the survival of women from breast cancer. © 2012 Taylor and Francis Group, LLC.
