Assessment of heavy metal and radioactive element levels in the ovarian follicular fluid of pregnant and non-pregnant Kyrgyz breed mares.

Objective: In the current study, we aimed to ascertain the levels of heavy metals and radioactive elements in the ovarian follicular fluids of pregnant and non-pregnant Kyrgyz mares.

Materials And Methods: To this end, follicular fluids were obtained from 49 Kyrgyz mares aged 3-5 years. The mares were in various stages of pregnancy (Group 1, 27) or were non-pregnant (Group 2, 22).

Refining the evolutionary tree of the horse Y chromosome.

The Y chromosome carries information about the demography of paternal lineages, and thus, can prove invaluable for retracing both the evolutionary trajectory of wild animals and the breeding history of domesticates. In horses, the Y chromosome shows a limited, but highly informative, sequence diversity, supporting the increasing breeding influence of Oriental lineages during the last 1500 years. Here, we augment the primary horse Y-phylogeny, which is currently mainly based on modern horse breeds of economic interest, with haplotypes (HT) segregating in remote horse populations around the world.

Microsatellite Diversity and Phylogenetic Relationships among East Eurasian Breeds with an Emphasis on Rare and Ancient Local Cattle.

We report the genetic analysis of 18 population samples of animals, which were taken from cattle () breeds of European and Asian origins. The main strength of our study is the use of rare and ancient native cattle breeds: the Altai, Ukrainian Grey, Tagil, and Buryat ones. The cattle samples studied have different production purposes, belong to various eco-geographic regions, and consequently have distinct farming conditions.

[The dynamics of recovery processes in ischemic stroke as shown by comparison of clinical and tomographic indices].

The aim of this study was to assess the relation between MRI-changes of the brain infarction (BI) and neurological status in patients with hemispheric ischemic stroke. Clinical and MRI examinations were performed in 70 patients (aged from 46 to 89 years, 37 females, 33 males) 1, 3, 7-10, 14 and 21-30 days (in all cases) and 2, 6 and 12 months (n=29) after stroke onset. On FLAIR-images the criteria of assessment of cystic and gliosis transformation were determined.
