Abstract

Two groups of experimental animals, each consisting of 12 rabbits, were subjected to local fractional irradiation with cobalt 60. Group I received the total dose of 2580 R during 13 days, group II - 5100 R during 24 days. The effects of irradiation were estimated on the strength of histological examination of the liver immediately and after 7, 15, 30, 60 and 90 days after the last exposition. The histological sections were stained with haematoxylin and eosin, and colour reactions were performed for argentaffine and collagen fibres and for glycogen, neutral fats, alkaline and acid phosphatase, ATP-ase, glycose-6-phosphatase, non-specific esterase and succinic acid dehydrogenase. It was found that the dose of 2580 R is safe for the liver. The effects of irradiation were slight and limited to weak catabolic disturbances in the form of mild steatosis of the liver and of a transient and short-lived fall of glycogen and rise of hydrolytic enzymes. More pronounced and intense changes were observed in the other group of animals. During the early period, the changes were of a retrograde character and were typical of the acute post-irradiation effect. There was necrosis of the walls of the blood vessels, of the epithelium of the bile duc...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.
