objective(s):hypoxia induces cellular oxidative stress that is associated with neurodegenerative diseases. here, the protective effects of ferulic acid (fa) on hypoxia-induced neurotoxicity in pc12 cells were evaluated. materials and methods:we investigated the effect of fa on pc12 cells subjected to hypoxia stress, in vitro. results:fa increased cell viability, prevented membrane damage (ldh r...
بشر امروز در عصر مدرن در حال غرق شدن در دنیایی از امواج و میدانهای الکترومغناطیسی میباشد.به دلیل گره خوردن حیات انسان مدرن با این امواج،لحظه ای وجود ندارد که بدن ما تحت تاثیر مستقیم این میادین در زندگی شهری نباشد.در قرن گذشته محیط زیست به دلیل حضور طیف وسیع و در حال گسترش میدانهای مصنوعی الکترومغناطیسی به شدت تغییر کرده است.کاربردهای روزمره در زمینه ی ارتباطی(زمینی و هوایی)،امور نظامی، دریانورد...

Methylmercury (MeHg)-resistant sublines of rat pheochromocytoma (PC12) cells were isolated by repeated exposure to stepwise increased concentrations of MeHg. One of the sublines (PC12/TM) showed an 8- to 10-fold increase in resistance to MeHg compared with parent PC12 cells on the basis of the concentration required for 50% inhibition (IC50) of growth. PC12/TM cells accumulated smaller amounts ...
objective(s): this study was designed to indicate whether different fractions from artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (dox) in rat pheochromocytoma cell line (pc12). material and methods:cell viability was determined by mtt assay. also, activation of caspase-3 and superoxide dismutase were evaluated...
Cytosolic phospholipase A2 (cPLA2) preferentially liberates arachidonic acid (AA), which is known to be elevated in Alzheimer's disease (AD). The aim of this study was to investigate the possible relationship between enhanced nitric oxide (NO) generation observed in AD and cPLA2 protein level, phosphorylation, and AA release in rat pheochromocytoma cell lines (PC12) differing in amyloid beta se...

گلوکوکورتیکوئیدها ترکیبات مهمی هستند که رشد، تمایز و مرگ سلولی را در سلول های مغز پستانداران در سرتاسر دوره زندگی تحت تاثیر قرار می دهند. گلوکوکورتیکوئیدها در سیستم عصبی فعالیت های مهمی مانند متابولیسم انرژی و تحریک پذیری را تحت تاثیر قرار می دهند. همچنین اثرات متابولیکی بر انواع بافت به ویژه کبد، شش و ماهیچه دارند. مورفین دارای اثرات وابسته به دوز بر رشد زوائد نورونی (اکسون ودندریت) در رده های...
Introduction: Parkinson's disease (PD) is a common neurodegenerative disorder characterized by progressive neuronal dysfunction. Growing evidence has shown that oxidative stress plays a crucial role in the pathogenesis of Parkinson's disease. Correspondingly, the current study evaluated the protective effect of topiramate in 6-hydroxydopamine induced oxidative stress and apoptosis in PC12 cells...
