Toward a model of learning innovation integration: TPACK-SAMR based analysis of the introduction of a digital learning environment in three Russian universities.

Digitalisation is penetrating higher education (HE) in Russia. The study explores how three Russian universities have been integrating the Skyes digital learning platform to transform English as a foreign language (EFL) educational practices. The article outlines the main characteristics of the platform, recounts the steps in adopting the technology and addresses the emerging changes to learning and teaching.

[THE IDENTIFICATION OF SIX CLASSES OF PSYCHOACTIVE SUBSTANCES IN VARIOUS OBJECTS USING TECHNIOUE OF IMMUNE CHROMATOGRAPHY].

The immune chromatographic test-systems were developed to detect psychoactive substances of six classes: opiates, amphetamines, cannabinoids, ecstasy, benzodiasepines, methadone. for the first time the simple techniques of preparation of samples were developed to fast detect the mentioned substances in such biological and non-biological objects as sweat fatty discharges, hair, urine, surface lavages, parts of plants, unknown substances. The presented techniques of preparation and analysis of samples require no special equipment and reagents.

[Prophylaxis of carbon bisulphide poisoning effects on lipid component of erythrocyte membrane in experiment].

Preventive injection of "Kalifen" extract of high cranberry before and during intoxication with carbon bisulphide appeared to preserve lipid component of RBC membrane in rats.

Quantitative assessment of regulatory proteins in blood as markers of radiation effects in the late period after occupational exposure.

The objective of this research was quantitative assessment of serum and membrane regulatory proteins in blood from nuclear workers as markers of radiation-induced alterations in immune homeostasis in the late period after protracted exposure of nuclear workers with different doses. The effector and regulatory lymphocytes were measured using a flow cytofluorometer in workers from the main facilities of the Mayak PA (aged ∼60 y up to 80 y) in the late period after combined exposure to external gamma-rays and internal alpha-radiation from incorporated 239Pu. The control group included non-occupationally exposed members of the Ozyorsk population matched by gender and age to the group of Mayak workers.

[Prevention of abnormal physiological and biochemical characteristics of red blood cells in carbon disulfide intoxication].

Experimental studies were conducted on 4 groups of 10 rats each: 1) intact animals (a control group); 2) inhalation of carbon disulfide at a concentration of 2.0 mg/m3 for 7 days; 3) prophylactic administration of the hepatoprotective agent Legalon (100 mg/kg of total polyphenols), followed by carbon disulfide inhalation for 7 days; 4) prophylactic administration of the biologically active additive Kalifen (100 mg/kg of total polyphenols for 7 days), followed by carbon disulfide inhalation. Animal survival after carbon disulfide inhalation was 80%; preadministration of Legalon or Kalifen increased survival up to 100%.
