Abstract

Using a 12-hour infusion of salmon synthetic calcitonin (S-CT), distinct and sustained inhibition of gastric acid and pepsin secretion has been demonstrated in 4 normal subjects, 3 patients with peptic ulcer disease and 3 high risk patients. In 3 patients with Zollinger-Ellison syndrome, treated in the same way, elevated serum gastrin was reduced by about 50% and acid secretion by more than 90%. In healthy volunteers oral administration of human synthetic CT (H-CT) led to reduction in basal and pentagastrin-stimulated acid and pepsin secretion by about 50%, lasting for more than 2 hours after the instillation of CT. In 4 subjects receiving CT intravenously, slight nausea and headache were registered, while there were no side effects after the oral route. Serum calcium did not change after i.v. or oral administration of CT. Wheras therapeutical applications of CT, given by i.v. route, seem to be restricted to selected cases, i.e. acute gastric ulcerations with imminent or existent bleeding, the eventual benefit or orally administered CT in peptic ulcer disease should be evaluated in controlled long-term trials.

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.
