multiple sclerosis (ms) is a neurodegenerative and autoimmune disease that it’s molecular etiology and factors involving in its progression remains unknown. in this study for evaluation effect of mercuric on progression of ms we investigated the additive effect of mercuric sulfide on the brain mitochondrial dysfunction in experimental autoimmune encephalomyelitis (eae) model of ms in c57bl/6 mi...

Objective(s) The mitochondrial defects in Friedreich's ataxia have been reported in many researches. Mitochondrial DNA is one of the candidates for defects in mitochondrion, and complex I is the first and one of the largest catalytic complexes of oxidative phosphorylation (OXPHOS) system. Materials and Methods We searched the mitochondrial ND4L gene for mutations by TTGE and sequencing on 30...

Introduction: Neurodegenerative diseases are progressive disorders that could impair neuronal functions and structures. Oxidative stress and mitochondrial dysfunction are involved in the etiology of neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease and etc. Gemfibrozil is used as a therapeutic drug for hyperlipidemia. It has been shown that gemfibrozil is n...

friedreichs ataxia (frda) is an autosomal recessive neurodegenerative disorder caused by decreased expression of the protein frataxin. frataxin deficiency leads to excessive free radical production and dysfunction of chain complexes. mitochondrial dna (mtdna) could be considered a candidate modifier factor for frda disease, since mitochondrial oxidative stress is thought to be involved in the p...

Mitochondrial dysfunction is estimated to be the primary reason involved in different types of neurodegenerative disorders as mitochondria suggested important production reactive oxygen species. Recently, several evidences have emerged out for impaired mitochondrial structures and functions viz. shape, size, fission-fusion, distribution, movement etc. diseases especially with Alzheimer’s diseas...

dacarbazine is an antitumor prodrug which is used for the treatment of malignant metastatic melanoma and hodgkin’s disease. it requires initial activation in liver through an n-demethylationreaction. the active metabolite prevents the progress of disease via alkylation of guanine bases in dna strands. in order to investigate the importance of imidazole ring and its dynamictautomerization in ant...

mitochondrial neurogastrointestinal encephalo-myopathy (mngie) is a rare autosomal recessive disease caused by thymidine phosphorylase (tp) gene mutation. here we report a patient with mngie in whom sensorimotor polyneuropathy was the first presenting symptom and had a fluctuating course. this 26-year-old female patient developed acute-onset demyelinating polyneuropathy from the age of 6 with t...
