Nephrotic syndrome, characterized by massive proteinuria, hypoalbuminemia and edema, is one of the most common kidney diseases in children. Although glucocorticoids (GCs), the mainstay of therapy for over 50 years, are effective in most children, more than 20% develop GC resistant nephrotic syndrome (SRNS), among whom focal segmental glomerular sclerosis (FSGS) is a frequent pathological outcom...

Focal segmental glomerular sclerosis (FSGS) is a major renal complication of mitochondrial (mt) cytopathies. The present study was designed to investigate the possibility of mtDNA lesion accumulation in podocytes, which are a primary pathogenic site of FSGS, during the development of glomerulopathy in puromycin aminonucleoside nephrosis (PAN). Two renal pathological phases of PAN, nephrosis pha...

A new mitochondrial disorder in heart failure that fits in the category of mitochondrial cytopathies is the exciting finding in the paper by Rosca et al. presented in this issue of Cardiovascular Research, which also explores a new insight into the functionality of mitochondria in the heart. The function of heart muscle is highly dependent on the energy generated by mitochondria by oxidation of...

objective(s): as mitochondrial oxidative stress is probably entailed in atp production, a candidate modifier factor for the long qt syndrome (lqts) could be mitochondrial dna (mtdna). it has been notified that ion channels' activities in cardiomyocytes are sensitive to the atp level. materials and methods: the sample of the research was an iranian family with lqts for mutations by pcr-sscp...

considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (ua), a soluble salt of depleted uranium (du). we examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (bht), to prevent ua-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. beta-glucan (150 nm) and bht (20 nm) attenuated ua-indu...

Neutropenic enterocolitis (NEC) is a life-threatening disease with substantial morbidity and mortality, seen primarily in patients with hematologic malignancies. The frequency of NEC has increased with the widespread use of chemotherapeutic agents such as the taxanes, which cause severe gastrointestinal mucositis. Neutropenic patients with fever and abdominal symptoms (cramping, pain, distentio...

background: mitochondria are autonomous cellular organelles that oversee a variety of functions such as metabolism, energy production, calcium buffering, and cell fate determination. most recently, mitochondrial dysfunction caused by mitochondrial mutations played important roles in the pathogenesis of asthma. however, the frequency of mitochondrial trna mutations in asthma is largely unknown. ...

Pioglitazone (PG) is one of thiazolidinediones used for the treatment of type II diabetes mellitus. Some reports of its hepatotoxicity exist, but the mechanism of its hepatotoxicity is not well known. In the present study, the protective effect of some ATP suppliers are investigated against mitochondrial toxicity of PG in isolated rat mitochondria. Mitochondrial viability was investigated by MT...

arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. it is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. we have already reported that liver is the storage site and important target organ in as ...
