The nucleus tractus solitarius and experimental neurogenic hypertension: evidence for a central neural imbalance hypothesis of hypertensive disease

Advances in Biochemical Psychopharmacology

Abstract

1. Interference with neuronal transmission through the NTS can result, depending upon species and mode of perturbation, in a panoply of abnormalities of blood pressure control simulating many of the features of the human disease. These are summarized in Table 1. 2. The abnormalities of pressure control resulting from abnormal transmission in NTS met most of the criteria of an animal model of central neurogenic hypertension. The only criterion yet to be met is that of pathology, a deficiency which may soon be overcome when animals, such as dogs, are maintained for prolonged periods of time. 3. The studies establish the possibility that subtle abnormalities involving neurochemical balances with NTS, resulting either from abnormal neurochemical transmission or variations of the organization of the nucleus with preponderance of one transmitter or deficiencies in others, can result in hypertension. 4. Impaired NTS function can produce an amplification of the action of the environmental stresses on blood pressure. Thus environmental stimuli or the expression of behaviors which normally result in trivial elevations of blood pressure will, after the NTS is perturbed, result in marked elevations. 5. A neural or neurochemical imbalance i...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.
