Comparison of the lytic effects of four prostaglandin analogues in the chacma baboon (Papio ursinus ursinus)

Six healthy, cycling female chacma baboons (Papio ursinus ursinus) were used to determine the luteolytic effects of four prostaglandin analogues. The compounds were administered according to a study design which made provision for adequate controls. Five to seven days following ovulation, venous blood was collected and the baboon given a single intramuscular injection of a compound at a recommended dose. Blood was then collected serially every 3 h for three samples and again at 24, 48, and 72 h to determine the continued effect of the prostaglandin analogues on corpus luteum production of progesterone. It was found that PGF2alpha-1,15-lactone, 11alpha(15S)-17-phenyl-18,19,20-trinor-ent-PGE2 methyl ester and 17-phenyl-18,19,20-trinor-PGF2alpha exhibited definite luteolytic potential in this species. Equivocal results were obtained with (15S)-15-methyl-PGF2Alpha THAM and its toxic qualities resulted in the demise of three animals.

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.
