Abstract

The development of hypertension in two-kidney, one clip renal hypertensive rats (2K, 1C RHR) was not altered by treatment with DOCA and saline solution as drinking fluid for two months of observation. However, the administration of DOCA and salt suppressed plasma renin activity (PRA), the renal renin content (RRC) of the clipped kidney and the response to a single oral dose of captopril (10 mg/kg). The weight of the contralateral kidney was increased by the administration of DOCA-salt, while that of the ischaemic kidney was not changed. The withdrawal of DOCA-salt treatment restored the PRA and the effects of captopril to a similar degree to the non-treated group. The acute hypotensive effects of captopril were reduced on the 10th week compared with the 7th week after renal arterial constriction in 2K, 1C RHR. The fall in blood pressure induced by captopril significantly correlated with the initial PRA both in the 7th and 10th week after clipping. There was a significant correlation between PRA and RRC of the clipped kidney. Rats previously treated with DOC-salt had either removal of the contralateral kidney with removal of the clip from the ischaemic kidney, or removal of the ischaemic kidney. Blood pressure fell to normal lev...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.
