Abstract

The amounts of plasma protein in eight groups of rats, A-H, was controlled by diet and a daily study was undertaken to investigate the effect that varying amounts of plasma protein have on body weight, the growth and development of body length, growth of the skull and mandible and development of the teeth. The following conclusions were obtained. 1. It was possible to keep the amount of plasma protein constant in each group by using a specially prepared diet containing differing amounts of casein. Also, when the rats with hypoproteinemia, due to a non-casein diet, were given food containing 24.5% casein, it was found that their plasma protein levels easily and quickly returned to normal. 2. Weight: Counting the first day of the experiment as 100, growth for group A (given a 24.5% casein diet) had reached 281.7% by the fifteenth week, whereas group H (fed a non-casein diet) reached a growth of only 48.5%--below half of day one of the experiment. On the other hand, each group which started out with a non-casein diet and later changed to a 24.5% casein diet recovered very quickly, but not to the extent of group A by the fifteenth week. Body length for all experimental groups increased from the first day to the third week, after wh...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.
