Breaking new ground on human health and well-being with epigenetic clocks: A systematic review and meta-analysis of epigenetic age acceleration associations.

Epigenetic clocks provide an accurate molecular readout of epigenetic age and epigenetic age acceleration (EAA) derived from DNA methylation data have shown promise as biomarkers of ageing. This systematic review synthesised research on associations between EAA measures and various physiological, cognitive, social, and environmental factors. A comprehensive search strategy identified 299 publications reporting 1050 unique EAA-factor associations based on 53 methylation clocks.

Open access-enabled evaluation of epigenetic age acceleration in colorectal cancer and development of a classifier with diagnostic potential.

Aberrant DNA methylation (DNAm) is known to be associated with the aetiology of cancer, including colorectal cancer (CRC). In the past, the availability of open access data has been the main driver of innovative method development and research training. However, this is increasingly being eroded by the move to controlled access, particularly of medical data, including cancer DNAm data.

Evaluation of Epigenetic Age Acceleration Scores and Their Associations with CVD-Related Phenotypes in a Population Cohort.

We evaluated associations between nine epigenetic age acceleration (EAA) scores and 18 cardiometabolic phenotypes using an Eastern European ageing population cohort richly annotated for a diverse set of phenotypes (subsample, = 306; aged 45-69 years). This was implemented by splitting the data into groups with positive and negative EAAs. We observed strong association between all EAA scores and sex, suggesting that any analysis of EAAs should be adjusted by sex.

Pathways resilient future for developing a sustainable E85 fuel and prospects towards its applications.

The utilization of ethanol as a component of motor gasolines is an extremely effective way to increase the detonation resistance and environmental properties. In Russia, despite the existing prerequisites for the development of bioethanol industry, the real production of bioethanol is not executed, which is associated with its high price. One of the promising ways of leveling this drawback is the utilization of water-cut waste from its production, involving ethyl alcohol impurity concentrate (EAIC) instead of pure ethanol.

[A NEW LOOK AT GILBERT SYNDROME (LITERATURE REVIEW)].

To illuminate modern ideas about Gilbert's syndrome (GS). GS is a common familial hyperbilirubinemia that can reduce the risk of various age-related diseases due to the antioxidant properties of bilirubin. In this case, slightly elevated unconjugated bilirubin in GS is strongly associated with a "reduced" prevalence of chronic diseases, in particular cardiovascular disease (CVD), as well as CVD-related and all-cause mortality.

[Cerebral metabolism in patients with cognitive disorders: a combined MRS and PET study].

Aim: Magnetic resonance spectroscopy (MRS) allows studying the content of many metabolites in neural tissue in vivo. There are numerous studies devoted to the MRS data analysis in Alzheimer's disease (AD), but their results are contradictory. Thus, it is rational to compare the data obtained with MRS and positron emission tomography (PET) with fluorodeoxyglucose (FDG), which allows evaluating the brain functional state.

[THE LEVEL OF PROTECTION FROM OXIDATIVE STRESS AND THREE-YEAR DYNAMICS OF STRUCTURAL AND FUNCTIONAL CHANGES OF THE MYOCARDIUM IN CHRONIC ISCHEMIC HEART DISEASE IN MEN].

Aim - to assess the nature and three-year dynamics of structural and functional changes in the cardiovascular system in relation to the levels of enzymatic and non-enzymatic antioxidants in chronic coronary heart disease in men. The study included 246 men aged 48 to 65 years (mean age 58 years (53,0; 63,0)) with stable form of ischemic heart disease - angina FC II-III CHF I-III FC (NYHA), observed during 2012-2015. To assess the level of oxidative stress in all patients by ELISA was determined by lipid peroxide, total antioxidant status (CCA) and levels of non-enzymatic antioxidant bilirubin (BR).

Feature binding in auditory modality requires attention as indexed by mismatch negativity and N2b in an active discrimination task.

Currently, there are two opposing views on feature binding in the auditory modality: according to behavioral studies, this process requires focused attention, whereas electrophysiological studies suggest that feature binding may be fully automatic and independent of attention. Here, we examined whether feature binding depends on higher-level attentional processes by manipulating the attentional focus. We used four auditory stimuli that differed in two features: pitch and location.

Distributed feature binding in the auditory modality: experimental evidence toward reconciliation of opposing views on the basis of mismatch negativity and behavioral measures.

Current understanding of feature binding remains controversial. Studies involving mismatch negativity (MMN) measurement show a low level of binding, whereas behavioral experiments suggest a higher level. We examined the possibility that the two levels of feature binding coexist and may be shown within one experiment.

[Oxygen-dependent energy deficit as related to the problems of ontogenetic development disorders and human sociobiological adaptation (theoretical and applied aspects)].

The review states and argues theoretical propositions on the pathogenetic role of pre- and perinatal hypoxic-ischemic brain damage in the formation of sustained oxygen-dependent energy deficit underlying in further ontogenesis the following neurobiological abnormalities: a) a decline in the level of health and compensatory-adaptive capacities of the organism, b) disorders of the psycho-speech development and adaptive behavior in children, c) early development of neuropsychic diseases, g) addition of other types of brain energy metabolism (including glucose metabolism) disorders in chronic polyetiologic diseases young and middle-aged individuals. We highlight and theoretically substantiate the integrated physiological parameters of the oxygen-dependent energy deficit types. We address the features of abnormalities in neuroreflectory and neurohumora regulatory mechanisms of the wakefulness level and its vegetative and hemodynamic provision in different types of energy deficit in children with DSMD, ADHD and school maladjustment.

[Genetic characterization of the rabies virus field isolates detected in Russian Federation within the period 2008-2011].

Sixty-three gene N fragments of rabies virus field isolates detected within the period 2008-2011 in different regions of Russian Federation were sequenced.
