The effects of prolactin (PRL), bromocriptine, testosterone propionate (TP), dihydrotestosterone (DHT), and the combinations of these androgens with PRL or bromocriptine on nucleic acids (RNA and DNA) and phosphomonoesterases (acid and alkaline phosphatase) of the seminal vesicles of castrated mature bonnet monkeys were studied. Castration decreased body weight, and seminal vesicle organ weight, nucleic acids and acid and alkaline phosphatases. TP/DHT replacement to castrates restored body weights and seminal vesicle DNA to normal and markedly increased the weight, RNA content and acid and alkaline phosphatase activities of the seminal vesicles. PRL did not alter body weight and increased the weight of the seminal vesicles, and their RNA content and phosphomonoesterase activities. PRL + TP/DHT enhanced all parameters. Bromocriptine given alone decreased body weight and acid phosphatase. Bromocriptine given along with TP/DHT suppressed the stimulatory influence of these androgens on most of the parameters studied. The results of the present study suggest that PRL has a specific stimulatory effect on seminal vesicle growth and function, that the presence of PRL is essential for androgen action, and that PRL acts synergistically w...Continue Reading

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.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
