Article Synopsis
  • Acclimation through the hormesis effect enhances flexibility in organisms, which has been confirmed in various ectothermic species, including the Baikal whitefish, by examining telomere length and gene expression.
  • The study found that while acclimation and acute temperature stress did not affect telomere length, they did influence telomerase activity, with acclimated larvae showing decreased activity and stressed larvae showing increased activity.
  • Acclimated larvae exhibited increased expression of genes involved in antioxidant defense, indicating a better ability to manage oxidative stress compared to non-acclimated larvae, along with changes in telomere-related gene expression under stress.

The dynamics of lung microbiota in tuberculosis remains poorly understood. Sequencing of variable regions of the 16S rRNA gene from surgically excised tuberculosis foci and biopsy specimens of normal lung tissue allowed characterization of the diversity and predictive potential of bacterial communities. Taxonomic diversity indices attested to differences in the structure of microbial communities between "healthy" lungs and tuberculomas.

Baikal sculpins are the most species-rich and ecologically diverse group of fishes in the Lake. We analyzed complete mitochondrial genomes from four species of the endemic Baikal genus (, , , and ). Mitogenome sequences are 16,523-16,535 bp in length with a mitogenomic organization and gene arrangement identical to that of typical teleosts.

This work simulates the consequences of HIREC using stone sculpins as model organisms. Sex-dependent effects of long-term noise exposure at mean sound pressure levels of 160-179 dB re 1 μPa (SPL) were measured. We applied a multilevel approach to testing the stress response: a comparative analysis of the macula sacculi and an assessment of hematological and molecular stress responses.

Lake Baikal is a natural laboratory for the study of species diversity and evolution, as a unique freshwater ecosystem meeting the all of the main criteria of the World Heritage Convention. However, despite many years of research, the true biodiversity of the lake is clearly insufficiently studied, especially that of deep-water benthic sessile organisms. For the first time, plastic waste was raised from depths of 110 to 190 m of Lake Baikal.
