Development and Initial Validation of the Russian Version of the RAADS-14: A Self-Report Questionnaire to Assess Autistic Traits.

Autism is a relatively common neurodevelopmental condition that affects social communication and behavior, affecting the overall quality of life. The prevalence of autism is constantly increasing, but timely diagnosis allows for effective treatment. The aim of our research was to construct a Russian version of the RAADS-14, a brief self-report questionnaire originally designed for autism screening, and to perform its initial validation to provide a reference point in developing autism self-assessment tools for the Russian-speaking population.

Mutagenic effect of gold nanoparticles in the micronucleus assay.

Mutagenic activity of gold nanoparticles of different sizes were studied by micronucleus assay. Karyological analysis was performed and the count of micronucleoli in interphase bone marrow polychromatic erythrocytes in white outbred rats was determined. The animals orally received gold nanoparticles 16 and 55 nm in diameter and gold nanoshells 160 nm in diameter once a day for 7 days in a dose of 0.

Epidemic diphtheria in the Kyrgyz Republic, 1994-1998.

The Kyrgyz Republic experienced a widespread diphtheria epidemic during 1994-1998. National diphtheria surveillance and vaccination coverage information were used to describe the course of the epidemic. The epidemic began in August 1994, reached a peak in 1995 with 704 cases (incidence rate: 15.

[The prevalence of the markers of viral hepatitis B and delta among the population in regions differing in the level of morbidity].

From two regions differing by the levels of incidence of hepatitis B, 2019 blood serum specimens from normal population were examined for markers of HBV infection. In Moscow, among 1040 samples examined HBsAg was found in 2.0%, anti-HBs in 10.

[Structure and antitumor activity of polysaccharides from the micelles of Aspergillus oryzae].

Three polysaccharide fractions active against mammary gland adenocarcinoma Ca-755 in mice but inactive against sarcoma C-180 were isolated from Aspergillus oryzae strain 5214. The main fraction, extracted from the mycelium by cold dilute alkali in the presence of sodium borohydride, was shown to be linear (1----3)-a-D-glucopyranan (pseudonigeran) according to 13C NMR spectroscopy, partial acid hydrolysis and periodate oxidation data.
