Abstract

Inorder to study the relationship between epidermal surface saccharides and pemphigus antigen(s), fluorescein-labelled Concanavalin A (Con A) and Phytohemagglutinin-P (PHA-P) were used. These phytohemagglutinins were found to bind with the intercellular areas of human epidermis. Alpha-methyl-D-mannoside and alpha-methyl-D-glucoside inhibited the epidermal intercellular staining pattern produced by ConA-FITC, while N-acetyl-D-galactosamine blocked the same staining pattern produced by PHA-P-FITC. Normal human skin reacted with pemphigus antibody and pemphigus skin with the deposition of IgG both gave a positive intercellular staining pattern with fluorescein labelled phytohemagglutinins. Our data indicated the non-identity of the binding of Con A and PHA-P, and pemphigus antigen(s).

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.
