A METHOD FOR IMPROVING THE PROFESSIONAL PERFORMANCE AND RELIABILITY OF PERSONS DRIVING HIGH-SPEED VEHICLES.

Recently, due to the emergence of a variety of modifications of air, land, water vehicles and an increase in their speed and maneuverability, the number of people with severe manifestations of motion sickness has also increased. The relevance of this problem is dictated by the fact that, despite significant achievements in the field of preventive medicine, a significant number of people prone to motion sickness have been observed to date. Thus, among persons using land modes of transport, the percentage of sick people reaches 15.

POSSIBLE ROLE OF KISSPEPTIN IN TESTOSTERONE-INDEPENDENT REGULATION OF SEXUAL MOTIVATION IN MALE RATS.

Kisspeptin is the peptide product of the KiSS-1 gene and endogenous agonist for the Kiss1 receptor. It is known that kisspeptin, acting centrally, stimulates secretion of gonadoliberin (GnRH). Kisspeptin interacts with other neuropeptides such as neurokinin B and dynorphin, to regulate GnRH pulse generation and also plays a role in sexual behaviour.

OX1R ANTAGONIST SB408124 ACTION AND EXTRAHYPOTHALAMIC CRF IN RATS AFTER PSYCHOTRAUMATIC EXPOSURE.

Corticoliberin (CRF) isn't only regulates hypothalamic-pituitary-adrenal axis activity, but also functions as a neurotransmitter in extrahypothalamic brain regions like amygdala, implicated in the emotional responses to stress. The CRF system provides an input to orexin neurons and can modulate the activity of orexinergic neurons in stress response. Some data showed the role of orexin-A in extinction of aversive memory.

UNEQUAL HORMONAL RESPONSE OF MALE AND FEMALE C3H-A MICE TO THE THYROID AND ANTITHYROID AGENT TREATMENTS.

The state of physiological functions of the whole organism, its vital activity and adaptation to various changes in the surrounding and internal environment is controlled by neurohumoral mechanisms. The main place in the implementation of those mechanisms belongs to hormones. A clinically relevant problem is currently the relationship between activity of thyroid gland and prolactin.

Sialidase NEU3 defines invasive potential of human glioblastoma cells by regulating calpain-mediated proteolysis of focal adhesion proteins.

Background: Glioblastoma multiforme is one of the most malignant tumors of the human central nervous system characterized by high degree of invasiveness. Focusing on this invasive nature, we investigated whether ganglioside-specific sialidase NEU3 might be involved, because gangliosides are major components of brain tissues, and cell surface sialic acids, as target residues of sialidase catalysis, are thought to be closely related to cell invasion.

Methods: NEU3 mRNA levels of human glioblastoma specimens were evaluated by quantitative RT-PCR.

Oxytocin-Induced Changes in Monoamine Level in Symmetric Brain Structures of Isolated Aggressive C57Bl/6 Mice.

Changes in activity of monoaminergic systems of the left and right brain hemispheres after administration of saline and oxytocin were studied in male C57Bl/6 mice subjected to social isolation. The concentrations of dopamine, norepinephrine, serotonin, and their metabolites dihydroxyphenylacetic, homovanillic, and 5-hydroxyindoleacetic acids were measured in the cerebral cortex, hippocampus, olfactory tubercle, and striatum of the left and right brain hemispheres by HPLC. In isolated aggressive males treated intranasally with saline, the content of serotonin and 5-hydroxyindoleacetic acid was significantly higher in the right hippocampus.

[The time course of experimentally altered thyroid status manifestations in female C3H-A mice].

The female C3H-A mice with agouty fur color were used to model hyper- and hypothyroidism in the long lasting experiment. The study was carried out for 44 weeks. Hyperthyroidism was induced by the administration of the L-thyroxine injections on alternate days during the whole period of the investigation.

The incidence of breast tumor during experimental hyperthyroidism.

The incidence of breast tumor in inbred C3H-A mice (virgin female) from hyperthyroid, hypothyroid, and euthyroid control groups at week 44 of the experiment was 86.67, 30, and 62.5%, respectively.

[Clinical and immunological efficiency of sodium nucleospermate in treating chronic endometritis and infertility complicated by HPV infection].

Clinical efficacy of sodium nucleospermate (SNS) has shown in the treatment of 26 female patients with chronic endometritis, unsuccessful attempts at in vitro fertilization, and persistent viral infection. Cells from endometrium were processed by liquid cytology and studied by immunocytochemistry techniques. It has been clearly established that, after SNS treatment, the frequency of CD20- and CD56-positive cells was significantly decreased (p < 0.

Sexual function in adult male rats after prenatal modulation of the cholinergic system.

Prenatal administration of the n-cholinolytic ganglerone to pregnant female rats at different periods of gestation was found to lead to long-term changes in sexual behavior in pubescent offspring: there was a reduced dynamic of acquiring sexual experience and a very low level of sexual activity, with significant impairment to the motivational and ejaculatory components of sexual behavior. The number of males with reduced sexual activity in the experimental groups was significantly greater than that in control offspring. The results obtained here provide evidence that impairments of sexual function in adult offspring induced by prenatal administration of the n-cholinolytic ganglerone at 9-11 and 12-14 days of gestation and, to a lesser extent, the m-cholinolytic metamyzil at 9-11 days of gestation, were due to impairment to the central mechanisms regulating sexual function due to stable changes in neurotransmitter activity in the hippocampus and hypothalamus, along with a significant reduction in the blood testosterone level.

Cells of rhabdomyosarcoma PA-23 tumor clones with high and low metastatic potential differ by activity of lysosomal sialidase.

We studied activity of lysosomal sialidase in cells of rhabdomyosarcoma PA-23 tumor clones with high and low metastatic potential. Low activity of lysosomal sialidase was found in clones characterized by high metastatic potential.

[The sexual function of mature rat males after prenatal modulation of cholinergic system].

The data obtained have shown that prenatal exposure of pregnant rat females of 9-19-day pregnancy to N-cholinolytics as compared to M-cholinolytics produce long-term behavioural changes in pubescent rat progeny. Pubescent rat progeny had low dynamics of gaining sexual experience and decreased sexual activity with equal disturbance of motivation and coitus. The number of males with absence of sexual activity was above that of the control group.

[Micronuclei in mucose cells and colonization of human stomach epithelium with coccoid forms of Helicobacter pylori].

Use of isopropyl alcohol in histological assays: dehydration of tissue, enbessing into paraffin, and processing of paraffin sections.

Isopropyl alcohol (isopropanol) can be used as a substitute for ethyl alcohol in tissue dehydration during embedding into paraffin and dehydration of stained sections. The use of isopropyl alcohol during paraffinization allows us to exclude treatment with intermediate solvents of paraffin (chloroform, xylene, and benzene), which reduces the degree of tissue compaction and simplifies and accelerates histological assay.

Modulation of neuritogenesis by ganglioside-specific sialidase (Neu 3) in human neuroblastoma NB-1 cells.

Plasma membrane-associated sialidase (Neu 3), which specifically hydrolyzes gangliosides, is relatively abundantly present in the nervous system. To understand the role of Neu 3 in neuronal differentiation, we studied the relationship between neurite outgrowth and Neu 3 expression in human neuroblastoma NB-1 cells. The expression of Neu 3 in NB-1 cells increased when neurite outgrowth in these cells was induced by dibutyryl cAMP.

[Structural changes of the nucleolar organizing regions in rhabdomyosarcoma RA-23 tumor cells induced by okadaic acid].

It has been recently shown that okadaic acid (OA), an inhibitor of dephosphorilation, is capable of inducing changes in the nucleolar organizer regions (AgNORs) of some mammalian cells. Our work was focused on studying the structural changes in AgNORs of tumour cells of rat rhabdomyosarcoma RA-23 by their exposure to 100 nM OA. A standard silver staining procedure of interphase AgNORs in tumour cells was used.
