Assessment of oxidative stress markers was perfomed in prostate cancer (PCa) patients subjected to high-dose brachytherapy (HDR) with external beam radiotherapy (EBRT). Sixty men with PCa were subjected to combined two-fraction treatment with HDR (tot. 20 Gy) and EBRT (46 Gy). Blood samples were taken before treatment, immediately afterwards, after 1.5-3 months, and approx. 2 years. Control gro...

BACKGROUND AND PURPOSE Heme-proteins, besides causing renal tubular obstruction, may contribute to rhabdomyolysis-induced renal injury through a heme-iron-mediated lipid peroxidation process. In the present study, we compared the combined therapy of a lipid peroxidation inhibitor, 21-aminosteroid (21-AS) and fluid-alkaline-mannitol (FAM) diuresis with either of them alone to determine the effic...

3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) can exert beneficial effects independently of serum cholesterol reduction by increasing the bioavailability of nitric oxide. However, it is unclear whether statins can exert such effects directly on cardiac myocytes and whether mitochondria are potential targets. Neonatal rat cardiac myocytes were cultured and subjec...

Erdosteine is a multimechanism, mucolytic agent that decreases the sputum viscoelastic properties and bacterial adhesion to the cell membrane, endowed with bronchial anti-inflammatory activity and a scavenging effect on free oxidant radicals. Erdosteine is a prodrug and metabolite I is the active metabolite of erdosteine owing to its free thiol group. In acute infective exacerbation of chronic ...

PURPOSE OF REVIEW The aim is to provide a detailed review of recent publications on cystic fibrosis-related diabetes (CFRD) with a particular focus on the interplay between cystic fibrosis (CF) lung disease and diabetes. RECENT FINDINGS CFRD is a form of diabetes that is distinct from type 1 or type 2 diabetes. CFRD remains very common and increases in prevalence with increasing age so that o...

Transient or permanent interruption of cerebral blood flow by occlusion of a cerebral artery gives rise to an ischaemic stroke leading to irreversible damage or dysfunction to the cells within the affected tissue along with permanent or reversible neurological deficit. Extensive research has identified excitotoxicity, oxidative stress, inflammation and cell death as key contributory pathways un...

INTRODUCTION Oxidative stress affects clinical outcome in critically ill patients. Although high-density lipoprotein (HDL) particles generally possess anti-oxidant capacities, deleterious properties of HDL have been described in acutely ill patients. The impact of anti-oxidant HDL capacities on clinical outcome in critically ill patients is unknown. We therefore analyzed the predictive value of...

objective(s): methylsulfonylmethane (msm) is a sulfur-containing compound found in a wide range of human foods including fruits, vegetables, grains and beverages. in this study the effect of msm pretreatment on acetaminophen induced liver damage was investigated. materials and methods: male sprague dawley rats were pretreated with 100 mg/kg msm for one week. on day seven rats were received acet...

This article discusses some of the mechanisms through which alcohol, delivered pre- or postnatally, alters the activity of the rodent hypothalamic-pituitary-adrenal (HPA) axis. We show that blockade of prostaglandin synthesis, but not opiate receptors, modestly interfered with the HPA axis to acute alcohol injection. Pretreatment with a low dose of alcohol (0.3 g/kg) did not significantly modif...

objective(s): biological applications of gold nanoparticles have limitations because of the toxic chemicals used in their synthesis. curcumin can be used as reducing as well as capping agent in synthesis of gnps to eliminate the cytotoxicity. conjugation of curcumin to gold also helps in increasing its solubility and bioavailability. materials and methods: here we report synthesis of gold nanop...
