The effect of hydroflumethiazide (HFT) on renal excretion of sodium, chloride, and potassium was studied in congestive heart failure and related to urinary excretion of thiazide and aldosterone. HFT 75 or 150 mg was administered orally once daily for 4 days to 8 male patients with roentgenological evidence of enlarged heart and slight or no peripheral oedema receiving digitalis and controlled diet. Urinary excretion of HFT did not change after repeated doses, whereas urinary excretion of a metabolite increased significantly. Initially, HFT induced a significant increase in the urinary excretion of sodium and potassium. After repeated doses, the natriuretic effect declined gradually in 6 of the patients. There was consistently a small natriuretic effect and a large kaliuretic effect at high serum aldosterone concentrations and high urine aldosterone excretion rates, whereas at low aldosterone levels, there was a wide range in magnitude of these effects. Relationships of the log urinary excretion rate of HFT to the increase in urinary excretion rate of sodium, chloride, and potassium showed positive and significant correlations. It was concluded that reduced natriuretic effect of HFT in congestive heart failure is not due to redu...Continue Reading

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.

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.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

Torsion Dystonia

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.
