low temperature plasma technology is well established in surface modification of polymer materials on industrial scale. this method modifies surface properties of polymers without chemicals, manual work and reducing chemicals and energy consumption. in this study, low pressure plasma treatment was used to develop hydrophilic properties of polyethylene terephthalate (pet) fabrics. it was found t...

background: obesity is associated with increased lipid peroxidation. it has also been suggested that risk of lipid peroxida­tion increases with increasing body iron stores. the aim of this study was to examine the association of body iron status with the concentration of plasma malondialdehyde (p-mda) as a marker of lipid peroxidation in obese and non-obese women. methods: in a case control stu...

background: endoscopic therapies can decrease the morbidity of patients with high risk peptic ulcer. the aim of this study was to evaluate the beneficial effects of oral omeprazole therapy in patients with bleeding peptic ulcer who received combined endoscopic treatment (epinephrine injection and argon plasma coagulation). materials and methods: eighty six patients with bleeding from gastric, d...

background: glycosidases profusion in male reproductive fluids suggests a possible relationship with sperm function. although hexosaminidase (hex) is the most active glycosidase in epididymal fluid and seminal plasma, as well as in spermatozoa, glucosidase is considered a marker for epididymal function and azoospermia. objective: the aim of this study was to determine hex activity in seminal pl...

background: sperm preparation is a fundamental step in art and attempt for developing new methods to be continued. objective: to evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility morphology and concentration. materials and methods: semen samples from 17 men who referred to infertility clinic for evaluating their ...

titanium and its alloy are known as important load-bearing biomaterials. the major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. the surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. different materials have been already used as coatings on biomedical implan...

essential hypertension (eh) accounts for 90-95% of hypertension cases. eh, as a progressive cardiovascular syndrome arising from complex and interrelated etiologies, results from combined and interactive effects of genetic and environmental factors. the objective was to investigate the ace i/d and gnb3 c825t polymorphisms and both genotypes combined with seeking gene-gene interactions to furthe...
