On the cells of neuroendocrine tumor of rats (line PC12) in culture was estimating of the governing mechanisms of the cytotoxicity of the oxidative stress and the role of the amyloids in increasing this stress. Using flowcytometric assessment of the cytotoxicity H2O2 and fragment beta-amyloid (Abeta) peptide (25-35) has been shown the dose-dependent increasing of the quote of the cells with DNA content < 2c. Isoeffective consentrations were 1 MM H2O2 and 5 MkappaM Abeta. The cytotoxicity H2O2 and A were accompanig with the increasing of the intracellular level of O2-. The treatment of the cells GSNO (donor of NO) and o-phenantrolin (chelators of Fe ions) significantly decreased the intracellular level of O2- as well as the cytotoxicity H2O2 and Abeta. Thus, in direct experiments has been shown of the part amyloids in the increasing of the oxidative stress and participation of the reactive oxide radicals in the cytotoxic effect of the Abeta. The addition argument which confirmed contribution of the oxidative stress in the cytotoxic effect of the Abeta was the similarity of the cellular response on the action of the oxidative agent - H2O2 and Abeta.

Background: Oxidative stress is strongly linked to neurodegeneration through the activation of c-Abl kinase, which arrests α-synuclein proteolysis by interacting with parkin interacting substrate (PARIS) and aminoacyl tRNA synthetase complex-interacting multifunctional protein 2 (AIMP2). This activation, triggered by ataxia-telangiectasia mutated (ATM) kinase, leads to dopaminergic neuron loss and α-synuclein aggregation, a critical pathophysiological aspect of Parkinson's disease (PD). To halt PD progression, pharmacological inhibition of c-Abl kinase is essential.

Background: Diabetes mellitus and periodontitis are two common chronic diseases with bidirectional relationship. Considering the role of oxidative stress in the pathogenesis of these two diseases, the use of nutritional supplements with antioxidant properties can be useful. The purpose of this study was to determine the effectiveness of daily synbiotic supplement in the management of patients with type 2 diabetes mellitus (T2DM) and periodontal disease (PD) under non-surgical periodontal therapy (NSPT).

The anthraquinone dye Alizarin Red S (ARS) is used for marking live animals, specifically as a tool for monitoring the stock of the endangered European eel by marking caught fish with ARS before releasing the eels back into the wild. As ARS can be found in recaptured eels even years later, knowledge of potential health hazards of ARS is essential for assessing the food safety of eels marked with ARS. As the compound class of anthraquinones is known for their genotoxic and carcinogenic properties, concerns were raised regarding the food safety of marked eels.

Doxorubicin (DOX) is a powerful antineoplastic FDA-approved anthracycline-derived antibiotic and is considered as the most suitable intervention for solid tumors and hematological cancers therapy. However, its therapeutic application is highly limited due to acute and chronic renal, hematological and testicular toxicity. Oxidative stress, lipid peroxidation and apoptosis in germ cells as well as low sperm count, motility and disturbing steroidogenesis are the principal machineries of DOX-induced testicular toxicity.
