Using Wistar rats as a model, this study explores the impact of MD followed by predator stress exposure (PSS) to simulate aspects of post-traumatic stress disorder (PTSD). A cohort of 41 male rat pups underwent MD from postnatal days 2 to 14, followed by PSS at day 90.

Three viral proteins, namely, helicase E1 and transcription factors E2 and E8^E2, are master regulators of the viral life cycle. HPV5 E2 is a transcriptional activator that also participates in the E1-dependent replication and nuclear retention of the viral genome, whereas E8^E2 counterbalances the activity of E2 and inhibits HPV transcription and replication.

This study was aimed to examine the prevalence of somatic and psychological distress among Russian university students.
Method: The cross-sectional study was conducted in March-April 2021.
The present study aimed to assess antibody seropositivity prevalence among symptomatic individuals and individuals with a high risk of occupational exposure to SARS-CoV-2. Participants from Chelyabinsk (Russian Federation) who were at an increased risk of exposure to SARS-CoV-2 (high-risk group, = 1091) and participants who either had symptoms consistent with COVID-19 or were suspected to have experienced COVID-19 in the past (symptomatic group, = 692) were enrolled between 28 September and 30 December 2020. Blood samples were tested by enzyme-linked immunosorbent assay D-5501 SARS-Cov-2-IgG-EIA-BEST and D-5502 SARS-Cov-2-IgM-EIA-BEST (AO Vector-Best, Novosibirsk, Russia).

Actively offensive rats with the externalizing indicators of sniffling and climbing the stimulus and material tearing during 10 days of predator scent stress had reduced plasma corticosterone, increased striatal glutamate metabolites, and increased adrenal 11-dehydrocorticosterone content compared to passively defensive rats with the internalizing indicators of freezing and grooming, as well as to controls without any behavioral changes. These findings suggest that rats that display active offensive activity in response to stress develop anxiety associated with decreased allostatic set-points and increased resistance to stress.

Methods: The blood and plasma collected postpartum from 100 mother-child pairs were analyzed using TTV-specific qPCR.
Motivation: In the systems biology era, high-throughput omics technologies have enabled the unraveling of the interplay of some biological entities on a large scale (e.g. genes, proteins, metabolites or RNAs).

In the yeast plasma membrane H(+)-ATPase, which belongs to a family of P2-ATPases, the loop is connected to M5 and M6 through the Asp-714 and Asp-720 residues. In this work, the effect of point amino, acidreplacements of Asp-714 and Asp-720 by Ala, Val, Asn, and Glu residues on the function of the enzyme was studied.

Under action of growth-stimulating concentrations of bioregulator stifun on wheat plants, an increase of functional activity of nucleoli of meristematic cells; contents of lectin (wheat germ agglutinin); and activity of proteinases, tripsin inhibitors, and ATPase activity was established. The pool of free amino acids was increased under bioregulator use. Levels of methionine, phenylalanine, cysteine, lysine, and tyrosine were increased.

A simple and convenient method for the quantitative evaluation of the activity of hydrolytic enzymes and their inhibitors has been proposed. This method is based on the immobilization of a substrate on agarose gel and the following evaluation of the enzyme activity by measuring the hydrolysis area around the well containing the enzyme solution. The method was shown to be applied to the evaluation of the activity of proteinases and amylases and the inhibitors of these enzymes in different biological objects.

Hypothesis: The study was performed to assess the magnitude of injuries and deaths due to landmines and unexploded ordnance in Chechnya between 1994 and 2005 and to describe epidemiologic patterns and risk factors for these events.
Methods: Surveillance data that included 3,021 civilian non-combatants injured by landmines and unexploded ordnance in Chechnya during 1994-2005 were analyzed.

The strains were isolated from the great cormorant (Phalacrocorax carbo), the crow (Corvus corone) and its collected Hyalomma marginatum nymphs. The types of interpopulational relations in the ecological system wild-birds-virus-mosquitoes-synanthroic birds-ticks are discussed.

Two methods of resection of the stomach by Billroth II were developed with creation of transversal termino-lateral gastroenteroanastomosis (TTLGEA) and transversal latero-lateral gastroenteroanastomosis (TLLGEA) using compression implant from nickel-titan alloy which possessed "memory of the form" (IMF). 231 resections of the stomach by Billroth II were carried out with formation TTLGEA in 181 cases and TLLGEA in 50 cases. Complications after these operations with compression gastroenteroanastomosis were studied as well as endoscopic and roentgenologic picture of the anastomosis in early postoperative period.
