[Treatment of diseases with consequences of traumatic brain injury].

Traumatic brain injury (TBI) is one of the leading causes of neurological morbidity, disability and mortality in all age groups of the population. As a result of the general increase in the number of cases of brain injuries, there is a significant increase in the consequences of TBI, the dominant part of which is asthenic, vegetative, cognitive, emotional and liquorodynamic disorders. Therapeutic measures in the long-term period of TBI should be carried out intensively as in the first 12 months.

[Vascular inflammation underlies the development of atherothrombotic stroke].

Atherothrombotic stroke is the one of the most common subtypes of ischemic cerebral circulatory disorders, the cause of which is atherosclerosis of the major arteries of the brain or their branches. The results of recent studies have shown that the atherosclerotic process is based on an inflammatory process in the vascular wall that leads to the initiation of atherosclerosis, endothelial dysfunction, oxidative stress, and the redistribution of various protein components in the blood-brain barrier. As a result, the progression of the described conditions leads to the manifestation of clinical symptoms and the formation of an acute vascular event.

[Oxidative stress and inflammation as links in a chain in patients with chronic cerebrovascular diseases].

Cerebrovascular diseases (CVD) are the main cause of death and permanent disability. The urgency of the problem of chronic CVD is associated with an increase of the absolute number of elderly and senile age in the population, a trend towards slowly increasing, sluggish pathological processes. It is obvious that any somatic disease in such patients is comorbid to cerebrovascular diseases that suggests a unified mechanism of the pathogenesis for both the main and concomitant diseases.

BRCA1-associated and sporadic ovarian carcinomas: outcomes of primary cytoreductive surgery or neoadjuvant chemotherapy.

Objective: Tumors arising in mutation carriers are characterized by increased platinum sensitivity; however, it is unknown whether this feature should be considered while choosing between primary surgical versus systemic treatment. This study aimed to compare outcomes of ovarian cancer patients undergoing either primary surgery or interval cytoreduction based on status.

Methods: The study included consecutive ovarian cancer patients, who were treated at the N.

[An association between human morphological phenotypical characteristics and the activity of chromosomal nucleolar organizer regions in the interphase cell nucleus in the population of indigenous people of Kursk region].

During the survey of 215 indigenous inhabitants of Kursk region, the activity of chromosomal nucleolar organizing regions (NOR) was examined in peripheral blood lymphocytes by a visual semiquantitative method based on silver salt impregnation (Howell W. M., 1975), and the general anthropometric indexes were determined.

Evaluation of the relationship between chromosome aberrations and transcription activity of nucleolus organizer regions in indigenous population of the Kursk region.

The relationship between activity of chromosomal nucleolus-organizer regions and levels of chromosome aberrations was studied in 215 residents of the Kursk region by visual semiquantitative method (silver staining of the nucleolus-organizer regions, NOR) in chromosomes of peripheral blood lymphocytes. The levels of chromosome aberrations differed significantly in three groups differing by the levels of 10AgNOR, which can be explained by different proliferative activity in these groups. The lowest level of chromosome aberrations was found in subjects with high transcription activity of NOR, presumably due to high proliferative activity in this group and more intensive synthesis of proteins, including the reparation enzymes.

[Construction of the genetically attenuated bacteria Bordetella pertussis devoid of dermonecrotic toxin activity and producing modified nontoxic pertussis toxin form].

The recombinant modified (attenuated) bacteria A. pertussis were constructed. These bacteria contained knockout mutation of the dnt gene and produced nontoxic pertussis toxin derivative.

Transcriptional activity of chromosome nucleolar organizing regions in population of Kursk region.

We studied population polymorphism of active nucleolar organizing regions in residents of the Kursk region and the association of activity of chromosomal nucleolar organizing regions with intensity of the synthesis of erythrocyte membrane protein. We revealed a tendency towards increasing of the amount of the major erythrocyte membrane proteins (primarily, spectrins and band 5 protein) with increasing total transcriptional activity of nucleolar organizing regions of chromosomes. The intensity of protein synthesis affects cell proliferation, determines the rate of tissue growth and its function, which determines its participation in the development of various diseases.

Relationship between the chromosome nucleoli-forming regions and somatometric parameters in humans.

Relationship between activity of nucleolar organizer regions in chromosomes and somatometric parameters was studied in residents of the Kursk region. Significant differences in the somatometric parameters were revealed between the three groups differing by the number of nucleolar organizer regions, which can be explained by different proliferative activities in these groups. A greater number of nucleolar organizer regions was associated with a trend to greater body weight and body mass index, waist and hip circumferences, waist to hip circumference ratio, and shoulder width in men and increased body height, greater body weight and body mass index, hip circumference, and leg length in women.

[A comparative study of the role of the yadA, invA, and psaA genes in the pathogenicity of Yersinia pseudotuberculosis].

The roles of yadA, invA, and psaA genes introduced into the genetic background of the Y. pseudotuberculosis strain possessing the large p VM82 plasmid in virulence and invasion capacity were studied. Isogenic single mutants as well as double and multiple mutants of these genes were constructed and used.

Evaluation of the dependence of mutagenesis intensity on activity of nucleolus organizer regions of chromosomes in Aboriginal population of Kursk region.

Visual semiquantitative method of silver staining of nucleolus organizer regions in peripheral blood leukocytes was applied for evaluation of the correlation between activity of nucleolus organizer regions and the level of chromosome aberrations in 241 residents of Kursk region. Significant differences in the percent of chromosome aberrations were revealed between three groups differing by the number of active nucleolus organizer regions, which can be explained by different proliferative activity in these groups. The lowest level of chromosome aberrations was found in individuals with high transcription activity of the nucleolus organizer regions (due to high proliferative activity in this group and due to more intensive protein biosynthesis, e.
