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.

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).

Fatty Acid Content of Four Salmonid Fish Consumed by Indigenous Peoples from the Yamal-Nenets Autonomous Okrug (Northwestern Siberia, Russia).

We assayed fatty acids in the flesh of Arctic cisco (adult and juvenile), least cisco , muksun , and Arctic charr inhabiting water bodies of the Gydan Peninsula, Siberia, Russia. The highest concentrations of total and polyunsaturated fatty acids (PUFAs) were found in Arctic charr (27.8 and 9.

Obesity and obesity-associated cardiometabolic risk factors in indigenous Nenets women from the rural Nenets Autonomous Area and Russian women from Arkhangelsk city.

Background: The prevalence of obesity and obesity-related conditions varies by population groups. Indigenous women of the circumpolar north are believed to be at high risk of obesity.

Objective: We studied, first the obesity prevalence in indigenous Arctic women, Nenets, compared to urban Russian women.

Serum apolipoproteins in relation to intakes of fish in population of Arkhangelsk County.

Background: Diets rich in omega-3 fatty acids and low in saturated fat were found beneficially associated with blood lipids and cardio-vascular health. Lean reindeer meet and local cold water white-fish species high in omega-3 are among the main sources of nutrients in the rural area of the Nenets Autonomous Okrug (NAO) in Russia and are not normally consumed by the urban population from the same region. The aims of the study were firstly, to compare serum lipid profiles of residents of urban (Arkhangelsk city) and rural (NAO) regions of Arkhangelsk County, and secondly, to investigate the effects of fish consumption on the predictor of cardiovascular events apolipoprotein (Apo) B/ApoA-I ratio in these populations.

The influence of active and passive smoking during pregnancy on umbilical cord blood levels of vitamins A and E and neonatal anthropometric indices.

Smoking during pregnancy has been shown to be detrimental for the developing fetus. The effects of active and passive maternal smoking on umbilical cord serum levels of vitamin A and vitamin E were examined. Secondary measures included anthropometric parameters in the newborn.

Fish consumption and socio-economic factors among residents of Arkhangelsk city and the rural Nenets autonomous area.

Objectives: The urban Russian and the rural Indigenous populations in the Russian European North have different lifestyles, living conditions and food supplies. The objective of this study was to investigate and compare fish consumption in relation to the socio-economic characteristics of 2 communities in Arkhangelsk County.

Study Design: A cross-sectional study.
