Biomarkers of Atherosclerotic Vascular Disease in Workers Chronically Exposed to Ionizing Radiation.

It is well established that cohorts of individuals exposed to ionizing radiation demonstrate increased risks of cardio- and cerebrovascular diseases. However, mechanisms of these radiation-induced diseases developing in individuals exposed to ionizing radiation remain unclear. To identify biomarkers of the atherosclerotic vessel damage in workers chronically exposed to ionizing radiation, this study considered 49 workers of the Russian nuclear production facility-the Mayak Production Association (mean age of 68.

Sum frequency generation spectroscopy of tetraalkylphosphonium ionic liquids at the air-liquid interface.

Sum frequency generation (SFG) spectroscopy is a nonlinear vibrational spectroscopic technique used in the study of interfaces, due to its unique ability to distinguish surface molecules that have preferential ordering compared to the isotropic bulk. Here, a series of alkyltrioctylphosphonium chloride ionic liquids, systematically varied by cation structure, were characterized at the air-liquid interface by SFG. The effect on surface structure resulting from molecular variation (i.

Immunological Markers of Chronic Occupational Radiation Exposure.

This study aimed to identify immunological biomarkers for prolonged occupational radiation exposure and thus studied a random sample of the Mayak Production Association worker cohort (91 individuals). The control group included 43 local individuals never employed at the Mayak Production Association. To identify biomarkers, two groups of workers were formed: the first one included workers chronically exposed to external gamma rays at cumulative doses of 0.

Expression of blood serum proteins and lymphocyte differentiation clusters after chronic occupational exposure to ionizing radiation.

This study aimed to assess effects of chronic occupational exposure on immune status in Mayak workers chronically exposed to ionizing radiation (IR). The study cohort consists of 77 workers occupationally exposed to external gamma-rays at total dose from 0.5 to 3.

The alternation effect in ionic liquid homologous series.

A recent report on a density odd-even alternation effect in a homologous series of ionic liquids (alkyltrioctylphosphonium chlorides, with the linear alkyl group ranging from ethyl to decyl) led to the detection of a similar trend in another ionic liquid family based on a different cation (1-alkyl-3-methylimidazolium). Ab initio calculations and Molecular Dynamics simulations of the corresponding ions confirmed that the charge distribution along the alkyl side chains and the conformations adopted by them are not the direct cause of the odd-even effect. The simulations also showed that all cation side chains tend to adopt transoid conformations that pack head-to-head in the liquid phase.
