Studies investigating exosomes isolated from cells exposed to photon radiation commonly used in conventional radiotherapy demonstrate the influence of this type of radiation on exosome characteristics and secretion. There is currently no research investigating the effects of densely ionizing particles such as protons and alpha radiation on exosomes. Thus we have evaluated the cellular response of human prostate cancer cells exposed to 0, 2, and 6 Gy of alpha radiation emitted from the Am-241 source. Irradiated PC3 and DU145 cell lines, characterized by differences in radiosensitivity, were studied using apoptosis, LDH, and IL-6 assays. Additionally, the corresponding concentration and size of isolated exosomes were measured using NTA. We found that exposure to ionizing radiation resulted in gross changes in viability and ...

MMPs may modulate various cellular and signaling pathways in atherosclerosis responsible for progression and rupture of atherosclerotic plaques. The effect of MMPs polymorphisms and the expression of MMPs in both the atherosclerotic plaque and plasma was shown. They are independent predictors of atherosclerotic plaque instability in stable coronary heart disease (CHD) patients. Increased levels of MMPs in patients with advanced cardiovascular disease (CAD) and acute coronary syndrome (ACS) was associated with future risk of cardiovascular events. These data confirm that MMPs may be biomarkers in plaque instability as they target in potential drug therapies for atherosclerosis. They provide important prognostic information, independent of traditional risk factors, and may turn out to be useful in improving risk strati...

An example of the role of genetic polymorphism is susceptibility to alcohol dependence in various ethnic groups (Hurley 2012). This review presents a wide spectrum of issues related to molecular mechanisms of ethanol biotransformation. Systematizing information concerning some aspects of the genetically determined polymorphism of enzymes involved in the oxidative and nonoxidative ethanol biotransformation pathways is a particular priority here. The article presents the main biochemical and genetic aspects of polymorphism of enzymes involved in the metabolism of ethyl alcohol in relation to clinical and diagnostic issues. Ethanol Absorption and Elimination Ethyl alcohol, as a compound with small, slightly less polar molecules than water, effectively penetrates biological membranes, and thus is efficiently absorbed along the entire length of the gastrointestinal tract and through the pulmonary alveoli. About 2% of the consumed dose of ethanol is absorbed from the oral cavity and oesophagus, 22% from the stomach and 75% from the small intestine. Once absorbed, ethanol spreads freely into all body's water spaces. So far, no ethanol-binding proteins have been detected in blood plasma (

Initially, pharmacological management is undertaken; however, surgical intervention is necessary to improve life quality and relieve symptoms in most cases. Here changes are reported in blood metabolome that occurred three days after the ileo-colic region resection in the case of seven patients. Alterations are observed in levels of metabolites associated with multiple mitochondrial pathways, based on the Metabolite Set Enrichment Analysis, reflecting a high energy demand in the post-operative period. As most of these metabolites are also essential nutrients supplied from foods, we believe that our results might contribute to the discussion on perioperative nutrition’s role in enhanced recovery.
