background: pinopodes are suggested as biological markers of uterine receptivity, but their molecular components are unknown. objective: co-expression of galectin-3 and ?v?3 integrin at human pinopodes has been examined in this study to propose a role for them during adhesion phase of embryo implantation. materials and methods: biopsies were obtained from early and mid luteal phase endometrium ...

aim: the aims of this study were to characterize iranian shigella sonnei strains isolated from pediatric cases and evaluate the utility of multilocus variable-number tandem-repeat (vntr) analysis (mlva) for genotyping of local s. sonnei strains. background: s. sonnei has become the dominant species in certain parts of iran. although pfge is still a gold standard for genotyping and source tracki...

soil compaction as a global problem and a multi-dimensional and complex process involving the interaction of climate, soil mashyn- plant- known to have a significant economic and environmental impacts and to sustainable agriculture is an intractable problem.for in order to assess compaction effect on nitrogen mineralization process in soil in form of factorial completely randomized design with ...

an efficient and eco-friendly protocol for the preparation of 2-amino-4h-chromenes employing a multi-component, one-pot condensation reaction between aromatic aldehydes, malononitrile and1-naphthol has been developed. the reaction of 1-naphthol with malononitrile and various aromatic aldehydes was carried out in water-ethanol (1:1) at reflux using 20 mol% of diammonium hydrogen phosphate as cat...

effects of different amounts of morning liming on blood ionic parameters and blood biochemical parameters of cultured carp ponds in dikjeh area of gonbad were investigated. 9 ponds (3 hectars) were chosen and divided in 3 treatments (1- liming 750 mg/l, 2- liming 1250 mg/l, 3- liming 1750 mg/l). liming had significant effect on blood hematocrite (p0.05) were observed between other blood paramet...

fue to the importance of selecting imaging parameters in magnetic resonance brain angiography, this study was carried out to choose optimum theoretical and experimental parameters for improving image controast and resolution and achieve shorter imaging time for practical reasons.a 1.5t super conductive magnet mri with gradient power of 13 nt/m and larmour frequency of 63 mhz with imaging coli o...

in this study two intelligent systems, based on adaptive neuro-fuzzy inference systems (anfis) and artificial neural networks (anns) of forecasting municipal solid wastes (msw) generation has been proposed. anfis and anns as an intelligent tool compared with together was used to monthly prediction of msw generated in tehran. monthly amount of solid wastes (sw), total monthly precipitation, mont...

normal 0 false false false en-us x-none ar-sa carotid body tumor (cbt) is paraganglioma and mainly found in the carotid bifurcation. the manifestations of the tumor are variable; in most cases, it presents as a non-symptomatic slow-growing mass, rarely compression of carotid body induces bradycardia and hypotension and repeated syncope, prolonged syncope can cause convulsion. convulsive syncope...

asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...

the genus tanacetum is one of the most important medicinal plants that contains 26 species in iran, 12 of them are endemic. this paper reports the essential oil composition of  tanacetum angulatum willd. tanacetum canacens dc. and tanacetum pinnatum boiss. growing wild in iran. plant flowers and leaves were collected from different locations of north- west of iran. samples were hydro-distilled ...
