Elimination of prostacyclin (PGI2) and 6-oxo-PGF1 alpha in anaesthetized dogs

The plasma concentration of 6-oxo-PGF1 alpha was measured by radioimmunoassay after constant rate infusion of 6-oxo-PGF1 alpha or prostacyclin (PGI2) into anaesthetized dogs. A steady-state plasma concentration was rapidly attained with both compounds. After termination of the infusions, the concentration of 6-oxo-PGF1 alpha declined according to a bi-exponential process. The steady-state plasma concentrations of 6-oxo-PGF1 alpha obtained after infusion of 6-oxo-PGF1 alpha and PGI2 were approximately 10 times higher than the corresponding steady-state level of PGF2 alpha measured after infusion of PGF2 alph into the same dogs. The data presented suggest that PGI2 and 6-oxo-PGF1 alpha are eliminated more slowly than PGF2 alpha, probably because they are not taken up and metabolized in the lungs as rapidly as PGF2 alpha.

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.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

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.
