Abstract

The evolution of postcoital contraception has led to the development of emergency measures to be used following a single unprotected act of intercourse and to ongoing methods, such as the administration of a contraceptive steroid agent following every coital exposure. In emergency situations, the most commonly employed hormonal steroids are the synthetic, conjugated and natural estrogens, administered in large doses for five days. Recently, a combination of an estrogen and a progestin has been employed for the same purpose. A copper-bearing intrauterine device (IUD), inserted within seven days of coitus, has also been utilized with success. Progestins alone have been utilized as an ongoing method of postcoital contraception. Failure rates have been found to vary with the dosage, the specific progestin employed and the frequency of intercourse. The major role of postcoital contraception in the developed world appears to be as an emergency measure. Ease of availability, a high degree of efficacy and a low incidence of side effects are essential for patient and physician acceptance.

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.

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory 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.

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.
