Abstract

Background Effects of drugs and biologically active supplements based on omega-3 polyunsaturated fatty acids (ω3 PUFA) considerably depend on the standardized content of eicosatetraenoic acid (EPA), docosahexaenoic acid (DHA), and other fatty acids in the extracts.Material and methods In this study, we comprehensively examined the composition of 10 ω3 PUFA samples with chromatographic measurement of more than 40 metabolites of fatty acids and other compounds. The data on extract composition were analyzed with current methods of intelligent data analysis (metric condensation method; multidimensional scaling; principal component analysis with axis identification; topology-metrical approach to recognition).Results Quantitative markers were obtained, which allowed separating the standardized ω3 PUFA-based samples (Omacor, Solgar omega-3 700, Femibion Natalker-2, Omega-3 concentrate, Omegamama) from less standardized ones (Fish oil-Teva, Omegatrin, Omeganol, etc.) based on results of a chromatographic analysis of fatty acid composition in the studied samples (EPA+DHA marker, ω6+ω11 marker, and standardization coefficient showing conformity of measured ω3 PUFA levels with the content stated by the manufacturer).Conclusions Among the ...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.
