According to the analysis of polymorphism of mitochondrial DNA (mtDNA) in eastern Slavs, the frequency of the BamHI-3/AvaII-9/MspI-4 and BamHI-3/AvaII-13/MspI-4 mitotypes are 14% and 3%, respectively. The mitotype BamHI-3/MspI-4 in relation to the (+)AluI/15606 variant was demonstrated to be identical in European populations. It is assumed that the unimodal distribution of the difference values between all pairs of nucleotide sequences of the control mtDNA region that correspond to the BamHI-3/MspI-4 mitogroup indicates an association between the increase of mitotypic diversity in this mitogroup and the exponential growth of European populations in the Neolithic period.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver condition, characterized by a spectrum that progresses from simple hepatic steatosis to nonalcoholic steatohepatitis, which may eventually lead to cirrhosis and hepatocellular carcinoma. The precise pathogenic mechanisms underlying NAFLD and its related metabolic disturbances remain elusive. Epigenetic modifications, which entail stable transcriptional changes without altering the DNA sequence, are increasingly recognized as pivotal.

The coexistence of type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) represents a significant global health challenge, contributing to substantial morbidity, mortality, and economic burden. T2DM is the leading cause of CKD, and CKD exacerbates diabetes-related complications, creating a bidirectional relationship driven by oxidative stress, inflammation, and endothelial dysfunction. Diabetic kidney disease (DKD), affecting some individuals with T2DM, accelerates progression to end-stage renal disease (ESRD) and increases cardiovascular mortality.

Many root-knot nematode (RKN) species in the genus occur in Florida, including , a species able to overcome RKN resistance genes in many crops. The distribution of these nematodes in horticultural crops is not well known. A RKN survey was conducted in South and Central Florida aiming to: (i) identify RKN infecting vegetables, fruit, and other crops; (ii) document host plants; (iii) determine RKN distribution; and (iv) gain insight on the relatedness of obtained in this study with other populations from the USA and other countries.

Adverse drug reactions (ADR) remain a challenge in modern healthcare, particularly given the increasing complexity of therapeutics. WHO's definition of an adverse drug reaction as a response to a drug that is noxious and unintended and occurs at doses normally used in man for the prophylaxis, diagnosis or therapy of disease, or for modification of physiological function. This definition underscores the importance of monitoring and mitigating unintended drug effects, particularly for widely used medications like valproic acid (VPA).

Understanding the molecular mechanisms that confer cold resistance in mammalian cells might be relevant for advancing medical applications. This study aimed to exploit the protective function of Late Embryogenesis Abundant (LEA) proteins, known to provide resistance to low temperatures in extremophiles and plants, by their exogenous expression in mammalian cells, and compare their effects with the well characterized antioxidant, vitamin E.Remarkably, the expression of LEA proteins in mammalian cells exerted cold-protective effect similar to Vitamin E.
