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. Source

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. Source

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.

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.

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.
