in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...

micrornas (mirnas) are a class of small non coding regulatory rnas that have key functions in multiple cell processes. deregulation of these tiny mirnas are involved in various human diseases. mir-155 is one of the multifunctional mirna that its over-expression has been found to be associated with different kinds of cancer such as leukemia, breast and colon cancers. it is thought that deregulat...

objective: several studies have implicated the 5-httlpr polymorphism in treatment outcomes of selective serotonin re-uptake inhibitors in patients with major depression. the aim of this study was to examine the association between polymorphism in the serotonin transporter gene and citalopram effectiveness in iranian patients suffering from major depressive disorder (mdd). methods: the sample co...

objectives in this study, we reported the identification of a cdna sequence encoding cysteine-free antimicrobial peptides isolated from venomous glands of this species. materials and methods total rna was extracted from the iranian mesobuthus eupeus venom glands, and cdna was synthesized by using the modified oligo (dt). the cdna was used as the template for applying semi-nested rt- pcr techniq...

background and objectives: the region of the experiment is located in golestan province, iran, with agriculture subject to various farming conditions (rain-fed and irrigation) and different levels of salinity (more than 38% of golestan’s total land area is salt-affected). the purpose of this study has been to evaluate the stress indices in the selection of tolerant wheat genotypes, not only for...

the release of pro-inflammatory cytokines is responsible for the variety of behavioral, neuro-endocrine and neuro-chemical alterations in psychiatric condition. in this study we evaluate relation between depression and il-6 and il-10 in patients undergoing hematopoietic stem cell transplantation (hsct).66 patients in this cross-sectional study from july 2013 until august 2014 for hsct interred ...

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...

many species belonging to the scrophularia genus have been used since ancient times as folk remedies for many medical conditions such as scrofulas, scabies, tumors, eczema, psoriasis, inflammations. the aim of this study was to characterize the matrix metalloproteinases (mmps) inhibitor compounds of the scrophularia striata extract by bio-guide fractionation. the aerial parts of s. striata were...

background:   purpose:   method:   results:   conclusion:

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...
