Abstract

The fatty acid composition of muscle lipids from eadible fish from Paraná river such as Dorado (Salminus maxillosus), Boga (Leporinus affinis), Patí (Luciopimelodus pati) and Surubí (Pseudoplatistoma coruscans) was studied in order to determine their food value in relation to essential fatty acid n-3 and n-6 supply. Flesh from these fishes is relatively lean and its lipids only contain 35% to 38% saturated fatty acids. Significant amounts of n-6 polyethylenic acids, mainly linoleic, arachidonic and the n-3 acids, docosahexaenoic, docosapentaenoic, eicosapentaenoic and alpha-linolenic are found in these fishes. Patí flesh is the most abundant in n-6 acids with a value of 306 mg/100 g muscle, followed by Boga, Dorado and Surubí. A large proportion of n-3 acids is supplied by muscles of Dorado, 183 mg/100g muscle, followed by Patí, Boga and Surubí. More than 90% of the lipids that supply these acids are present in triacylglycerols in Dorado, Boga and Patí. In Surubí, triacylglycerols constitute 60% and the remaining lipids are phospholipids. Cholesterol content in flesh of fresh water fish was analyzed, and it did not exceed 4.7 micrograms/g muscle for Patí, being lower for the other species studied. Fish considered in this work r...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.
