introduction:this study examined the effects of administration of subcutaneous β-estradiol on ptsd-like symptoms (the enhanced conditioned fear response, cfr) that induced by a single-prolonged stress (sps) and shock in rats. adult male wistar rats were exposed to sps procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. then the rats were placed in fear conditioning syste...

background: colors make many problems and these are major sources of environmental pollution. therefore, this wastewater should be treated before discharge to environment to reduce the environmental threats. adsorption is one of the usual processes for color removal from wastewater. nanotube s are new adsorbents with extend application for adsorption of different compounds. aim of this study wa...

objective: to investigate the association of c631t single nucleotide polymorphisms in spo11 gene with male infertilityfollowed by an in silico approach. spo11 is a gene involved in meiosis and spermatogenesis process, which in humans, this gene is located on chromosome 20 (20q13.2-13.3) with 13 exons. materials and methods: in a case-control study, 200 blood samples were collected from the ivf ...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

background: artemisinin is commonly used for the treatment of malaria, but recently has been considered as a potential substance to control poultry coccidiosis. objectives: the aim of the present study was to determine the tissue distribution of artemisinin following single or multiple oral administration of different doses in broiler chickens. methods: a total number of 390 one day old ross br...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

objectives: the present study aimsed to examine the reliability of forceplate parameters under both single and dual task conditions and in different levels of postural difficulty. methods & materials: the healthy elderly+65, were assessed with aone-week interval, with a random combination of three levels of postural difficulty (i.e., standing on a rigid surface with eyes open, standing on a rig...

background: molecular components of the dopamine receptor (drd3) play an important role in the pathophysiology of schizophrenia (scz). previous studies have demonstrated an association between the drd3 ser9gly polymorphism and scz but the results have been inconclusive. method: in this study, we investigated this controversial association between the ser9gly (a/g) polymorphism and scz using mal...

there are several known and unknown factors for unexplained recurrent spontaneous abortion (ursa). among them, complement regulatory protein cd46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. we aimed in this study to investigate the possible association of cd46 ivs1-1724 c>g polymorphism with rsa in iranian women. 141 women w...

aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as selex. in the amplification and regeneration step of selex technique, dsdna is conversed to ssdna. asymmetric pcr is one of the methods used for the generation of ssdna. the purpose of this study was to design a random dna library for selection of aptamers wit...
