chitosan/polyethersulfone (cs/pes) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. the substrate membrane was prepared by phase inversion technique using polyethersulfone (pes) and dimethylacetamide (dmac) as solvent with and without the addition of polyvinylpyrrolidone (pvp) as pore-forming agent. the effects of the composition of the c...

spinal muscular atrophy (sma) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. the survival motor neuron (smn) protein level reduces in patients with sma. two different genes code survival motor neuron protein in human genome. skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...

Precise investigation of genetic diversity by means of novel molecular tools has made it possible to identify the superior genotypes among various male and female pistachio populations. Cytogenetic studies have shed light on the possible presence of distinct sex chromosomes in male and female genotypes. In this study, 22 start codon targeted (SCoT) primers were used to investigate the genetic d...

Genetic study of pistachio, especially male genotypes due to the effects of pollen on nut quality and quantity and next generation characterizations, help to improve its management and breeding programs. We studied the genetic diversity among 20 male and 36 female pistachio genotypes using ISSR marker. In total 178 DNA frgments were proliferated using 12 primers that 169 fragments were polymorp...

ab initio calculation at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the important energyminimumconformations and transition-state geometries of of cyclodeca-1,2,3-triene (1). the mostfavorable conformation of 1 is a unsymmetrical twist-chair (1-tc) structure. degenerateinterconversion of 1-tc with it...

Sarcocystis is one of the most prevalent parasites of domestic ruminants worldwide. This study was aimed to determine prevalence of Sarcocystis infection and molecular discrimination of Sarcocystis gigantea and Sarcocystis medusiformis infecting domestic sheep. Tissue samples from 638 sheep slaughtered at Urmia abattoir were randomly collected from February 2011 to January 2012. Genomic DNA ext...

conclusions the genotype distribution of hcv takes diverse patterns in emro countries. genotypes 1 and 3 were predominant in iran and pakistan, while genotype 4 and 1 were the most common genotypes in the middle east arab countries and north african arab countries. understanding the genotypes of hcv can help policy makers in designing good strategies for treatment. results a total of 563 record...

this review deals with studies that have used cdna microarrays and immunohistochemistry to identify a subtype of breast carcinoma recently known as “basal-like” carcinoma. the key breast carcinoma studies are critically discussed to highlight methodological problems in cohort selection, definitions, interpretation of results, and statistical analysis. it concludes that “basal-like” carcinomas d...
