The character of Lake Kishkensor contamination in the area of underground nuclear explosions at the Semipalatinsk Test Site territory.

The timely identification of areas where man-made radionuclides migrate through water streams is highly important for the territory of the former Semipalatinsk Test Site since the aquatic environment is currently a source of secondary contamination of environment. This article presents research findings on radioactively contaminated Lake Kishkensor located at the Semipalatinsk Test Site territory. As a result of this research, a new locally contaminated spot was discovered in the vicinity of the "Balapan" test site.

Localization data of the T-DNA insertion site in Arabidopsis line SALK_146824C.

The present work reports on the determination of localization of T-DNA insertion in SALK_146824C line. The line is characterized as deficient in GDP-l-galactose phosphorylase 1 () gene encodes a protein involved in ascorbate biosynthesis. Primer pairs allow to distinguishing SALK_146824C from wild type plants and to the exact localization of the insertion were designed used.

[Assessment of relationship of lipid and carbon profile indicators with vitamin D supply in children depending on body mass index].

Overweight children represent a particularly vulnerable group for hypovitaminosis D. Clinical studies on the relationship between vitamin D (VD) deficiency and metabolic risk factors for cardiovascular disorders are controversial, and for children of primary school age who have overweight and obesity are insufficient. of the research was to study the relationship between lipid and carbohydrate metabolism indicators and VD status in children, depending on the body mass index.

[Vitamin D status and calcium-phosphoric metabolism in children with excessive body weight and obesity].

Obesity is a multifactorial disease, the prevalence of which has increased over the past few decades worldwide in all age groups. There is evidence of the pathogenetic role of vitamin D (VD) in the formation of obesity. However, there are few studies concerning the characteristics of calcium-phosphorus metabolism in obese children.

Effect of single injection of pentylenetetrazole in a subconvulsive dose on Cl- conductance of the GABAA-receptor complex.

Muscimol-stimulated Cl(-)conductance in brain cortex synaptoneurosomes from Wistar rats decreased 15 min after single intraperitoneal injection of pentylenetetrazole in a subconvulsive dose. These changes reflected a decrease in functional activity of the GABA(A)-receptor/Cl(-)ionophore complex. Muscimol-stimulated Cl(-)conductance in synaptoneurosomes returned to normal 48 h after pentylenetetrazole administration.
