background: the progressive accumulation of misfolded and aggregated proteins in neurons is an accepted mechanism in aging. overproduction of reactive oxygen species (ros), referred to as oxidative stress, is currently believed to play a pivotal role in this process. lipofuscin as a histological index of aging results from cross-links between oxidized proteins and lipids. therefore, to attenuat...

background: endometriosis is defined as the existence of endometrial-like tissue outside the uterus. diagnosis of endometriosis is a challenging theme. despite the broad search for innovative laboratory tests and advances in imaging technologies, there are still no easy, non-invasive diagnostic tests available. due to inflammatory process of endometriosis, still c-reactive protein (crp) level m...

objective:  to assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation. materials and methods: thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. periodontal parame...

background: increased serum high sensitive c-reactive protein (hs-crp) in asthma and its association with disease severity has been investigated in many studies. this study aimed to determine serum hs-crp status in asthma versus healthy controls and to examine its ability in predicting asthma control. methods: serum crp was measured by elisa method using a high sensitive crp kit. severity of as...

background: reactive oxygen species (ros) are a group of free radicals that in excessive amounts have negative influence on sperm quality and function. objective: to study the effect of varicocele and its severity on the level of ros in infertile men with clinical varicocele. materials and methods: in this controlled prospective study, 42 men with clinically diagnosed left varicocele and 30 fer...

background: reactive oxygen species (ros) are a group of free radicals that in excessive amounts have negative influence on sperm quality and function. objective: we compared ros levels in seminal plasma of infertile men with this level in healthy donors. we also determined the ros level in semen of infertile men according to the etiology of infertility, and also the effect of smoking on its le...

objective: oxidative stress plays a key role in the pathophysiology of brain ischemia and neurodegenerative disorders.previous studies indicated that viola tricolor and viola odorataare rich sources of antioxidants. this study aimed to determine whether these plants protect neurons against serum/glucose deprivation (sgd)-induced cell death in an in vitro model of ischemia and neurodegeneration....

introduction : surgical removal of inferior third molar tooth is associated with post-operative complications such as pain, trismus and edema. decreasing the post-operative inflammation and edema is one of the important goals in drug administration. for management of post-operative pain, nonsteroidal anti-inflammatory drugs (nsaids) and opioids can be administered. c-reactive protein (crp) is o...

background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...
