Abstract

Urinary excretion of 6-keto-PGF1 alpha and 2,3 dinor-6-keto-PGF1 alpha, as indices of the renal and systemic production of prostaglandins, was measured during water immersion in a group of 6 healthy volunteers both in the presence and absence of dopamine blockade by the dopamine receptor antagonist, metoclopramide. Urinary flow rate and excretion of both sodium and 6-keto-PGF1 alpha increased during water immersion, while plasma renin activity and plasma aldosterone were reduced. Urinary kallikrein and 2,3 dinor-6-keto-PGF1 alpha also tended to increase during water immersion. Administration of metoclopramide significantly reduced 6-keto-PGF1 alpha and sodium excretion during water immersion, but produced no changes in plasma renin activity or in 2,3 dinor-6-keto-PGF1 alpha. Plasma aldosterone concentrations after metoclopramide were similar to those observed in the pre-immersion period. An increased synthesis of the vasodilator and natriuretic prostacyclin in the kidney might play a role in the response to water immersion. The reduced sodium and 6-keto-PGF1 alpha excretion observed after metoclopramide administration suggests that dopamine might induce prostacyclin synthesis in the kidney during water immersion.

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.
