Exploring ultrasonic communication in mice treated with Cannabis sativa oil: Audio data processing and correlation study with different behaviours.

Studying ultrasonic vocalizations (USVs) plays a crucial role in understanding animal communication, particularly in the field of ethology and neuropharmacology. Communication is associated with social behaviour; so, USVs study is a valid assay in behavioural readout and monitoring in this context. This paper delved into an investigation of ultrasonic communication in mice treated with Cannabis sativa oil (CS mice), which has been demonstrated having a prosocial effect on behaviour of mice, versus control mice (vehicle-treated, VH mice).

[Evaluation of antioxidant properties of enriched bakery products in experiment on laboratory animals].

The purpose was to study the effect of enriched bakery products in the diet of rats on indicators of prooxidant-antioxidant system of blood serum. Experiment was carried out on male Wistar rats with initial weight 140-180 g. After a quarantine during the preparatory period rats for 14 days were accustomed to the partial (50%) replacement of the standard diet by bakery products with standard compound­ing.

Treatment and disease progression in a birth cohort of vertically HIV-1 infected children in Ukraine.

Background: Ukraine has the highest HIV prevalence (1.6%) and is facing the fastest growing epidemic in Europe. Our objective was to describe the clinical, immunological and virological characteristics, treatment and response in vertically HIV-infected children living in Ukraine and followed from birth.

Factors associated with abandonment of infants born to HIV-positive women: results from a Ukrainian birth cohort.

Social marginalisation and other challenges facing HIV-positive pregnant women in Ukraine may put them at increased risk of relinquishing their infants to the state. We described rates of infant abandonment (exclusive non-parental care to most recent follow-up, censored at two years of age) and investigated associated factors using logistic regression models, in 4759 mother-infant pairs enrolled across six Ukrainian sites in the European Collaborative Study from 2000 to May 2009. Median maternal age was 26.

Previous reproductive history and post-natal family planning among HIV-infected women in Ukraine.

Background: Ukraine has the highest antenatal HIV prevalence in Europe. The national prevention of mother-to-child transmission (MTCT) programme has reduced the MTCT rate, but less attention has been given to the prevention of unintended pregnancy among HIV-positive women. Our objectives were to describe the reproductive health, condom use and family planning (FP) practices of HIV-positive childbearing Ukrainian women and to identify factors associated with different methods of post-natal contraception.
