Objective: The aim: To establish the dynamics of changes in the average total diameter, the diameter of the lumen of microvessels in the cortex of the rats' adrenal glands influenced by the long-term action food additives complex.

Patients And Methods: Materials and methods: To determine the structural changes of the vessels of the hemomicrocirculatory bed of the cortex of the adrenal glands of rats in our study, we used histological, morphometric and statistical methods.

Results: Results: During the study, we found that the effect of a food additive complex on the vessels of the adrenal glands cortex of rats leads to a violation of hemodynamic conditions in the early stages of the experiment.

To estimate the changes of the intensity of the NeuN-immunoreactivity reaction in the structural components of the cerebellum of rats under the influence of the food additives complex. We used 100 white rats with an average weight of 258.1±0.

Objective: The aim: To define the degree for glial acidic fibrillary protein expression on the structural components of cerebellum of the rats in health and when rats influenced by the food additives complex.

Patients And Methods: Materials and methods: In order to determine the degree of expression of the immunohistochemical marker GFAP on the structural components of the cerebellum of rats we applied immunohistochemical, morphometric and statistical methods in our study.

Results: Results: In histological specimens at the end of 1st week of observation in the gray matter of the cerebellum there occurred a gradual increase in 1.

This study uses population genomic data to estimate demographic and selection parameters in two sister lineages of the wild yeast Saccharomyces paradoxus and compare their evolution. We first estimate nucleotide and recombinational diversities in each of the two lineages to infer their population size and frequency of sex and then analyze the rate of mutation accumulation since divergence from their inferred common ancestor to estimate the generation time and efficacy of selection. We find that one of the lineages has significantly higher silent nucleotide diversity and lower linkage disequilibrium, indicating a larger population with more frequent sexual generations.

Objective: Introduction: Chronic inflammatory diseases of the mucous membranes of the nose, paranasal sinuses, and pharynx are the most common pathology of the upper airways. Pathological processes develop more often in the maxillary and ethmoidal sinuses than in the frontal ones; however, the clinical course of frontitis is more severe. Fundamental understanding of the specific structure of frontal sinuses is crucial in the awareness of the precursors of the onset and development of its pathology, the choice of methods of diagnostics and treatment.
