Fatty Acids in the Eggs of Red King Crabs from the Barents Sea.

The red king crab, , was introduced into the Barents Sea where, after a period of 30 years of adaptation, it has established a new population. This population has been commercially exploited over the past two decades, supporting profitable fisheries in both Russia and Norway. Biochemical studies aimed at assessing fatty acid profiles have been conducted, focusing primarily on the edible parts of red king crabs.

Analysis of , , , , , and Gene Expression Levels in Peripheral Blood of Patients with Early Stages of Parkinson's Disease.

Parkinson's disease (PD) is a common chronic, age-related neurodegenerative disease. This disease is characterized by a long prodromal period. In this context, it is important to search for the genes and mechanisms that are involved in the development of the pathological process in the earliest stages of the disease.

Fatty Acid Profiles in the Gonads of Red King Crab () from the Barents Sea.

Red king crab () is a large shelf species native to the Pacific Ocean. Due to its high commercial value, this species was introduced into the Barents Sea, where it has formed a new population that now supports a stable commercial fishery. Information on fatty acid profiles in different tissues of the Barents Sea is scarce.

Age-related features of the content of substrates of energy metabolism and body mass index in women residing in the Subarctic and Arctic regions of Russia.

Objectives: Age is associated with a number of health risks linked to obesity caused by an imbalance in the main energy substrates-fatty acids (FA) and glucose (Glu). Therefore, the objective of this study was to identify age-related features of the metabolism of fatty acids and Glu, their correlations and the relation with the body mass index (BMI) in women of the local Caucasoid population from two northern regions of Russia with different nature, climate, and geography.

Methods: We examined women aged 21-60 years born and permanently residing in the Subarctic region (SR) and the Arctic region (AR).

Keratinolytic Properties of Promising for Biodegradation.

The high demand for keratinolytic enzymes and the modest presentation of fungal keratinase diversity studies in scientific sources cause a significant interest in identifying new fungal strains of keratinase producers, isolating new enzymes and studying their properties. Four out of the 32 cultures showed a promising target activity on protein-containing agar plates- A6, VKPM F-1593, 247, and 1779. The highest values of keratinolytic activity were demonstrated by extracellular proteins synthesized by VKPM F-1593 cultivated under submerged conditions on a medium containing milled chicken feathers.

Vermiculite as a new carrier for extracellular protease production by spp. under solid-state fermentation.

A new method has been developed to increase the productivity of aspergilli - producers of extracellular proteinases based on their cultivation on vermiculite under solid-state fermentation conditions. The productivity of the mycelium L-1 and 1 was 3-18 times higher not only in comparison with submerged cultivation, but also in comparison with growth on other carriers studied under solid-state fermentation conditions. Vermiculite can be considered as a new promising carrier for solid-state fermentation of micromycetes.

Combined microbiological approach to screening of producers of proteases with hemostasis system proteins activity among micromycetes.

A scheme for screening of micromycetes - producers of proteases with the activity of hemostasis system proteins, based on their enzymatic indices determination and the activity towards chromogenic peptide substrates for proteins of the hemostasis system was developed. Depending on the ability of proteases producers to cleave such substrates, an enzymatic reaction in conditions containing human plasma is suggested, which makes it possible to identify the potentiality of the target plasma hemostasis proenzymes activation.
