The study is conducted in 2019 in the Moscow region (Russian Federation) and Almaty region (Republic of Kazakhstan). The study sample includes 800 cows (400 animals at each of the two locations), 100 at each of the 4 cattle farms in the Moscow region and 100 at each of the 4 cattle farms in the Almaty region.

Features of the clinical picture of keratitis in horses with different forms of the course of the disease.

Background: Keratitis is a common cause of eye diseases in horses, often resulting in complete loss of vision.

Aim: The purpose of this article is to study the features of the clinical picture of primary and secondary keratitis in horses, depending on the form of the course of the disease.

Methods: The study was conducted in 2019 at 22 private horse breeding farms.

Prediction of gene expression regulation by human microRNAs in Plasmodium falciparum.

Background: Malaria is a disease annually causing over 400,000 deaths. Deep understanding of molecular and genetic processes underlying its life cycle and pathogenicity is required to efficiently resist it. RNA interference is a mechanism of the gene expression regulation typical for a wide variety of species.

[THE SIGNIFICANCE OF THE SYSTEM APPROACH IN THE STUDY OF THE GENERAL ADAPTATION SYNDROME' REACTIONS].

The article discusses the problems of the process of environmental adaptations appearance which are based on the general principles of functional systems' constitution. The value of the theory of functional systems development as the basis for physiological cybernetics (P. Anokhin, 1935) is also given.

Nonrandom distribution of oncogene amplifications in bilateral breast carcinomas: Possible role of host factors and survival bias.

Amplification of HER2, C-MYC and CCND1 oncogenes is a hallmark of breast cancer (BC); however, its involvement in the bilateral form of this disease has not been investigated yet. In this study, 50 bilateral BC (biBC) pairs (100 tumors) and 72 control unilateral BC were examined using real-time PCR analysis of microdissected archival tissues. In biBC, the frequency of >3-fold oncogene amplification was 6/100 (6%) for HER2, 6/100 (6%) for C-MYC and 7/100 (7%) for CCND1.
