Response of Circulating Inflammatory Markers to Intermittent Hypoxia-Hyperoxia Training in Healthy Elderly People and Patients with Mild Cognitive Impairment.

Intermittent hypoxia-hyperoxia training (IHHT) is a non-pharmacological therapeutic modality for management of some chronic- and age-related pathologies, such as Alzheimer’s disease (AD). Our previous studies demonstrated significant improvement of cognitive function after IHHT in the patients with mild cognitive impairment (MCI). The present study further investigated the effects of IHHT on pro-inflammatory factors in healthy elderly individuals and patients with early signs of AD.

Bioethical problems arising in the study of single-nucleotide gene polymorphisms of occupational diseases.

In Ukraine, about 3 million people work in hazardous and dangerous conditions. The study of hereditary specificity in development of occupational diseases is being actively conducted through molecular genetic analysis of single-nucleotide gene polymorphisms. While studying single-nucleotide gene polymorphisms of occupational diseases, many complicated bioethical questions arise regarding the confidentiality of personal data, the choice between the profession chosen and the risk to one's own health.

Intermittent Hypoxia-Hyperoxia Training Improves Cognitive Function and Decreases Circulating Biomarkers of Alzheimer's Disease in Patients with Mild Cognitive Impairment: A Pilot Study.

Alzheimer's disease (AD) affects not only the central nervous system, but also peripheral blood cells including neutrophils and platelets, which actively participate in pathogenesis of AD through a vicious cycle between platelets aggregation and production of excessive amyloid beta (Aβ). Platelets adhesion on amyloid plaques also increases the risk of cerebral microcirculation disorders. Moreover, activated platelets release soluble adhesion molecules that cause migration, adhesion/activation of neutrophils and formation of neutrophil extracellular traps (NETs), which may damage blood brain barrier and destroy brain parenchyma.

Cholesterol enriched diet suppresses ATF6 and PERK and upregulates the IRE1 pathways of the unfolded protein response in spontaneously hypertensive rats: Relevance to pathophysiology of atherosclerosis in the setting of hypertension.

Many studies have been dedicated to hypertension and hypercholesterolemia, as they are the primary conditions that influence the unfolded protein response (UPR). However, the concurrent effects of these two factors are unknown. Our research used spontaneously hypertensive rats (SHR) fed a cholesterol enriched diet (CED) as model of atherosclerosis formation to discover what effect the simultaneous actions of hypertension and hypercholesterolemia have on the UPR.

Allelic polymorphisms of dna repair genes and their influence on the formation of resistance to the development of bronchopulmonary pathology under the action of industrial aerosols.

Objective: Introduction: The frequency of alleles and genotypes of DNA repair genes in people working due to the influence of industrial aerosols (miners and workers of asbestos-cement plants (n = 215)) was studied. The aim of the work was to identify allelic polymorphisms affecting the formation of resistance or leading to an increased risk of developing bronchopulmonary pathology.

Patients And Methods: Materials and methods: In 90 patients with bronchopulmonary pathology and 125 persons working under the same conditions but without respiratory system diseases, the polymerase chain reaction in real time was determined by the polymorphisms of DNA repair genes: XPD (rs13181, rs799793), ERCC1 (rs11615), XRCC1 ( rs25487) and XRCC3 (rs861539), ATM (rs664677), XRCC7 (rs7003908) and MLH1 (rs1799977).

GenCoNet - A Graph Database for the Analysis of Comorbidities by Gene Networks.

The prevalence of comorbid diseases poses a major health issue for millions of people worldwide and an enormous socio-economic burden for society. The molecular mechanisms for the development of comorbidities need to be investigated. For this purpose, a workflow system was developed to aggregate data on biomedical entities from heterogeneous data sources.

Search for New Candidate Genes Involved in the Comorbidity of Asthma and Hypertension Based on Automatic Analysis of Scientific Literature.

Comorbid states of diseases significantly complicate diagnosis and treatment. Molecular mechanisms of comorbid states of asthma and hypertension are still poorly understood. Prioritization is a way for identifying genes involved in complex phenotypic traits.

Molecular Relationships between Bronchial Asthma and Hypertension as Comorbid Diseases.

Comorbidity, a co-incidence of several disorders in an individual, is a common phenomenon. Their development is governed by multiple factors, including genetic variation. The current study was set up to look at associations between isolated and comorbid diseases of bronchial asthma and hypertension, on one hand, and single nucleotide polymorphisms associated with regulation of gene expression (eQTL), on the other hand.

Correction to: Cardiospecific deletion of αE-catenin leads to heart failure and lethality in mice.

The original version of this article unfortunately contained a mistake. The published paper presented an incorrect version of Table 1. The corrected Table is given here.

Cardiospecific deletion of αE-catenin leads to heart failure and lethality in mice.

αE-catenin is a component of adherens junctions that link the cadherin-catenin complex to the actin cytoskeleton. The signaling function of this protein was recently revealed. In the present study, we investigated the role of αE-catenin in the pathogenesis of heart failure.

Proteasome Inhibition Diminishes the Formation of Neutrophil Extracellular Traps and Prevents the Death of Cardiomyocytes in Coculture with Activated Neutrophils during Anoxia-Reoxygenation.

Objective: Polymorphic mononuclear neutrophils (PMN) are very important cells participating in nonspecific defense of the organism. Among their well-known functions, the formation of neutrophil extracellular traps (NET) is interesting and potentially dangerous for the mechanisms of other cells. Ubiquitin-dependent proteasomal proteolysis is a very important regulator of all cellular activities, but the role of proteasomal proteolysis in NET formation has not been investigated.

Knockdown of PSMB7 induces autophagy in cardiomyocyte cultures: possible role in endoplasmic reticulum stress.

Proteasomal and autophagic pathways of protein degradation are two essential, endoplasmic reticulum (ER)-associated proteolytic systems involved in the ER stress response. The functional interaction between them has been shown by proteasome pharmacological inhibition. However, little data have been found concerning autophagy induction using an RNA interference approach due to the multisubunit composition of proteolytic systems.
