SSR Variability of Stem Rust Pathogen on Spring Bread Wheat in Russia.

Wheat stem rust, caused by f. sp. , which used to be a harmful disease of winter wheat in the southern part of Russia, has been largely affecting the yield of spring bread wheat in the territories of the temperate climate zone since 2009.

Resistance of winter wheat varieties to tan spot in the North Caucasus region of Russia.

Tan spot caused by (Died.) Drechsler, in recent years, occupies an increasingly large area on the territory of Russia. Due to the wide distribution and economic significance of this disease, the search for resistant plants to the pathogen is relevant.

Preparation and Properties of Soluble Pig Skin Fractions Influencing on Human Keratinocyte Proliferation and Differentiation.

Three fractions with different molecular weights were isolated from pig skin. Fraction 1 (F1) and fraction 3 (F3) stimulated human keratinocyte proliferation in primary and regenerating cultures, but didn't affect their differentiation. Fraction 2 (F2) inhibited keratinocyte proliferation and stimulated their differentiation.
