Carbohydrate-related nutritional and genetic risks of obesity for indigenous northerners

Abstract

By the end of the 2010-s the prevalence of obesity among the indigenous people of the North approached to the all-Russia one and the speed of the spread of other metabolic disorders exceeded the average all-country levels. Aim of this review is to analyze data on the increase in consumption and variety of sugars coupled with a genetic specificity of regulation of saccharidase activity and their possible impact on the matters. Results. It have been shown that the traditional protein-lipid-based northern type diet has substantially changed and now contains a high proportion of carbohydrates. The carbohydrate per capita consumption among the indigenous people of the North has reached the all-Russia average level (40 kg per year) which exceeds the European average of 36.2 kg per year. The variety of food disaccharides has also considerably increased. The daily consumption of sucrose, at the beginning of the 20th century it was the only sugar contained in the store-bought foods, increased from 30 g in the 1930s to 63-65 g in the 1990s. In addition, the proportion of sucrose dropped to 60-70 per cent, while the contribution of other disaccharides (lactose, trehalose) reached 30-40 per cent. Daily starch consumption has also increased...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
