The pool of free amino acids (AAs) in the blood serum was studied in two European migratory bat species, Vespertilio murinus and Pipistrellus nathusii, of the Urals. Bats from this year's bloods were examined, and significant differences were observed in main metabolic groups of free AAs, including glycogenic (GGAAs), nonessential (NEAAs), essential (EAAs), and sulfur-containing (SCAAs) AAs (p < 0.05).

A multivariate nonparametric ANOVA of red blood parameters showed significant interspecific differences (p < 0.05) between the migrating bats and the resident species pond bat.

- The study investigates the impact of exogenous pollutants, particularly from harmful working conditions and smoking, on the reproductive health of women with liver dysfunction.
- Researchers categorized women into four groups based on their liver enzyme activity and exposure to harmful substances, examining various reproductive indicators such as vaginal discharge and pH levels.
- Findings indicated that women exposed to harmful conditions and tobacco showed significant reproductive system changes, including higher instances of candidiasis and bacterial vaginosis, compared to the control group.
Article Synopsis
- The study investigates how juvenile adjuvant-induced arthritis (JAA) affects dental health in rats, focusing on carious tooth lesions.
- Experimental rats showed a significant increase in the number and depth of carious lesions compared to intact rats, with JAA leading to 100% prevalence of dental caries among them.
- The findings highlight the detrimental impact of autoimmune diseases like JAA on dental health, indicating a shift toward more severe carious cavities in affected rats.
Objective: Aim: A comprehensive evaluation of the effectiveness of the use of plant test-systems as biological objects for the identification of the specifitown of the effect of mutagens on the hereditary apparatus.
Patients And Methods: Materials and methods: With the use of test-systems (determination of the gonadotoxitown of plant pollen grains, the Allium cepa-test and the use of celandine greater Chelidonium majus as an accumulative phytoindicator) was analyzed the ecological situation of the areas in Ivano-Frankivsk region. The samples of soil, water, generative and vegetative organs of plants were taken in the territories of the Carpathian region and tested in the following areas: ecologically safe, conditionally ecologically safe and ecologically dangerous areas.
