acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. ftir studies revealed that the degree of grafting increased by an increase in acrylamide concentration. maximum grafting was obtained at 7 minute...

Background: The present systematic review and meta-analysis is designed in order to assess the association between passive and active smoking and lipid profile of children and adolescents. Materials and Methods:  An extensive search was done in databases of Medline, EMBASE, Web of Science, Scopus and CINAHL until October 2017. Two independent researchers screened articles and in the next step, ...

an extensive study was undertaken to investigate on the overall film badge service performance with which occupational radiation, exposures are reported in iran, the study involved the analysis of film badges exposed to x-and gamma rays and beta particles. for test exposures, x-rays between 60 and 140 kvpco-60 gamma radiation and sr-90 beta particles were used. the actual delivered dose equival...

The authors evaluated the contributions of nine genetic (G) variants (selected from 275 single nucleotide polymorphisms in 11 reverse cholesterol transport pathway genes), five environmental (E) factors (selected from 10), and G x G, E x E, and G x E interactions in explaining population variance of blood lipid concentrations. Total cholesterol, triglycerides, and high density lipoprotein (HDL)...

Early developmental exposure to di(2-ethylhexyl) phthalate (DEHP) has been linked to a variety of neurodevelopmental changes, particularly in rodents. The primary goal of this work was to establish whether acute postnatal exposure to a low dose of DEHP would alter hippocampal dendritic morphology and BDNF and caspase-3 mRNA expression in male and female Long Evans rats. Treatment with DEHP in m...

Introduction: Over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. This in vivo study was planned for evaluating the effects of whole-body exposure to 950 MHz field of GSM mobile phone system on rat dentate gyrus long-term potentiation. Materials and Methods: 24 naive male Wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

Abstract: Nickel was electrodeposited onto copper substrates with high {111} and {400} peak intensities. The grain size of coatings deposited onto the copper substrate with a higher {111} peak intensity was finer. Spheroidized pyramid morphology was obtained at low current densities on both copper substrates. By increasing the deposition current density, grain size of the coating was increased ...

background: serum lipids abnormalities have been observed in various forms of cancers including acute leukemia. investigators report decreased total cholesterol and hdl, and elevated triglyceride in leukemic patients. limited studies had been performed to discover the correlation between abnormal lipids profile and disease activity in leukemic patients in iran. this study was done to evaluate t...

abstract probiotic products highly affect the health of consumers by reducing the risk of heart attacks and improving of desirable microflora in intestinal tract. in this study the effect of yogurt (500g/d for 3 wk) enriched with either bifidobacterium bifidum or lactobacillus acidophilus on the level of cholesterol, low density lipoprotein (ldl) and high density lipoprotein (hdl) of serum and ...
