Abstract

Abortion was successfully induced in 62 of 68 patients in the 9th to the 26th week of pregnancy be serial intramuscular administration of 15(S)-15-methyl-prostaglandin F2alpha (15-ME-PGF2alpha). In 6 patients who failed to abort after 24 hours of prostaglandin administration, a concomitant infusion of oxytocin was initiated; 5 of these patients aborted within 12 hours of the combined therapy. A single patient failed to abort, even with the combined therapy, and underwent surgical evacuation. The mean abortion time in the 67 successful inductions was 14.56 hours. Parous patients aborted somewhat fasteter, mean 13.98 hours, as compared to nulliparous patients, mean 15.02 hours, but this difference was not statistically significant. In this study initial intramuscular injection of 100 mug 15-ME-PGF2alpha was followed in 1 hour by 250 mug and then 250 mug every 2 hours with concomitant oxytocin therapy initiated after 24 hours. The results with this dose schedule were compared to the results obtained in a previous study with a higher dose schedule, an initial dose of 100 mug 15-ME-PGF2alpha, followed in 1 hour by 250 mug then 500 mug every 2 hours. There was significant difference in the mean abortion time and the incidence of side...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.
