Hypothalamic stimulation of prolactin release in a freshwater catfish, Heteropneustes fossilis

Annales d'endocrinologie
R Singh, T P Singh

Abstract

Hypothalamic extract has been found to contain certain factor(s) which triggers the release of prolactin from the pituitary gland. In assay recipients, hypothalamic extract injection was as effective as perphenazine-HCl treatment in triggering the release of prolactin from pituitary gland. Rise in prolactin concentration of serum and resultant decrease in pituitary prolactin level in response to hypothalamic extract administration suggests that hypothalamus in H. fossilis has prolactin releasing factor(s). This releasing effect of hypothalamus seems to be specific since cortical extract injections were ineffective in producing the similar response.

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.

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.
