background and aims . periodontitis is a multifactorial disease. varieties of microbial and environmental, as well as genetic factors are reported to influence risk for periodontitis. the present study sought to test the putative involvement of il-10 and il-18 gene polymorphism in pre-disposition to periodontitis in patients had exposure to chemical agent as a risk factor for periodontitis deve...
in this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(bb) and tropaeolin o(to) in food samples using cloud point extraction (cpe) prior to spectrophotometric determination. the effects of main factors such as ph, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...
background and purpose: the 2-chlorophenol (2-cp) and 4-chlorophenol (4-cp) are phenolic compounds which may have adverse effects on human and environment. therefore, removing these compounds from water and wastewater is necessary. this study aims to analyze 2-cp and 4-cp removal by using azolla filiculoides biomass. materials & methods: azolla biomass was sun dried, crushed and sieved to parti...
the variants of angiotensin converting enzyme (ace) and matrix metalloproteinases (mmps) genes might be involved in the pathogenesis of end stage renal disease (esrd) and hypertension. we studied the ace insertion/deletion (i/d) and mmp-7 a-181g variants in 99 unrelated esrd patients and 117 individuals without renal complications from western iran with kurdish ethnic background. the frequency ...
background : cryptosporidium parvum is a ubiquitous protozoan, which develops within the microvillous membrane of enterocytes in a wide variety of vertebrates, including man. cryptosporidiosis is an important parasite causing severe diseases in the immunodeficient people especially aids patients. cryptosporidiosis has been also reported as a com-mon serious primary cause of outbreaks of diarrhe...
The synthesis and X-ray diffraction analysis of a new acidic salt, [4-methyl-phenyl ammonium][(O-phenyl)(hydroxyl)phosphate], [4-CH3-C6H4NH3][(C6H5O)P(O)(O)(OH)], is reported. This compound crystallizes in the monoclinic system, with space group P21/c (a = 9.5147(4) Å, b = 23.2158(10) Å, c = 13.2740(6) Å and b = 111.244(4)°) with four independent components including two cations and two anions...
