High-Power-Density Thermoelectrochemical Cell Based on Ni/NiO Nanostructured Microsphere Electrodes with Alkaline Electrolyte.

Effective low-grade waste heat harvesting and its conversion into electric energy by the means of thermoelectrochemical cells (TECs) are a strong theme in the field of renewable energy investigation. Despite considerable scientific research, TECs have not yet been practically applied due to the high cost of electrode materials and low effectiveness levels. A large hypothetical Seebeck coefficient allow the harvest of the low-grade waste heat and, particularly, to use TECs for collecting human body heat.

Development of DNA aptamers for visualization of glial brain tumors and detection of circulating tumor cells.

Here, we present DNA aptamers capable of specific binding to glial tumor cells , , and for visualization diagnostics of central nervous system tumors. We selected the aptamers binding specifically to the postoperative human glial primary tumors and not to the healthy brain cells and meningioma, using a modified process of systematic evolution of ligands by exponential enrichment to cells; sequenced and analyzed ssDNA pools using bioinformatic tools and identified the best aptamers by their binding abilities; determined three-dimensional structures of lead aptamers (Gli-55 and Gli-233) with small-angle X-ray scattering and molecular modeling; isolated and identified molecular target proteins of the aptamers by mass spectrometry; the potential binding sites of Gli-233 to the target protein and the role of post-translational modifications were verified by molecular dynamics simulations. The anti-glioma aptamers Gli-233 and Gli-55 were used to detect circulating tumor cells in liquid biopsies.

Clinical application of chromosome 9p21.3 genotyping in patients with coronary artery disease.

The aim of the present study was to investigate the susceptibility of two coronary artery disease (CAD)-associated single nucleotide polymorphisms on 9p21 ( and ) to myocardial infarction (MI) in a primary (stratification of high risk group for MI) and secondary prevention setting. The prospective observational study included 500 patients with MI [411 males (82.2%) and 89 females (17.

Melanoma Screening Day in Krasnoyarsk Krai of the Russian Federation: Results from 2015-2016.

Objective: The Melanoma Screening Day Campaign started in the Russian Federation in 2006. In the present study, we analyzed the 2015-2016 survey questionnaire data acquired from screened individuals in the city of Krasnoyarsk in eastern Siberia, which has a population of one million, in order to understand the level of awareness regarding melanoma/ skin cancer prevention and early diagnosis. Methods: Individuals were enrolled in the screening campaign by mass media advertising.

Prevalence of arterial hypertension in the Krasnoyarsk Krai (Siberia, Russia).

Background: To estimate the prevalence, awareness, treatment and control of arterial hypertension among adult inhabitants of Krasnoyarsk Krai using the data from Russian multicenter epidemiological study ESSE-RF (Epidemiological Survey of cardiovascular diSEases in different regions of the Russian Federation).

Methods: The study included 1603 subjects 25 to 64 years old selected by means of systemic multistage stratified randomization among urban and rural inhabitants of Krasnoyarsk Krai recruited between February 2014 and June 2014. Office blood pressure (BP) was measured twice with "Omron" automated BP device on the right arm in the sitting position in presence of medical personnel.
