Proso millet is a valuable short-term crop of universal use cultivated all over the world. However, due to the lack of genetic improvement, the yield of this crop does not provide stable in-come for farmers. The research is aimed to test proso millet germplasm of different geographical origin under different agro-climatic regions in Kazakhstan.

Drought is a primary ecological stress limiting wheat yield in water-deficient regions. Conducting targeted genetic selection of wheat cultivars can expedite the adaptation process of wheat to the climatic conditions of the region, allowing for the identification of high-yielding varieties with stable genetic traits. This study investigated the impact of the TaGW8 and TaGS3A genes, known for their contribution to wheat productivity.

Adhesive properties of leucocytes were studied using an original technique based on the leukocyte adherence inhibition reaction and measuring the values of spontaneous adhesion index (SAI) and adhesion-strengthening effect (ASE) under the influence of autoserum. One hundred patients with multiple sclerosis (MS) and 53 controls were included in the study. Immunophenotyping of lymphocytes (LP) with monoclonal antibodies--markers CD3, CD4, CD8, CD16, CD20, CD25, HLA-DR and CD95--and determination of IgG, IgA, IgM and content of immune complexes were carried out in parallel.

Adhesive blood properties have been studied in 100 MS patients with the help of the new method developed on the basis of the leucocyte adherence inhibition (LAI) test, which was based on the calculation of the ratio of adhesive cells to non-adhesive ones. The value obtained was called the Index of Spontaneous Adhesion (ISA), while the respective indicator reflecting the effect of adhesion strengthening under the influence of autoserum, being expressed by 30% and more, was named the Effect of the Adhesion Strengthening (ES-a). Blood samples of 54 donors and 31 patients with other neurological diseases were used as controls.

The influence of laser therapy on the course of Parkinson's disease (PD) was studied in 70 patients. This influence appeared adaptogenic both in the group with elevated and low MAO B and Cu/Zn SOD activity. Laser therapy resulted in reduction of neurological deficit, normalization of the activity of MAO B, Cu/Zn-SOD and immune indices.
