Abstract

The impact of intraluminal acid and pepsin on the rate of esophageal luminal release of transforming growth factor alpha (TGF alpha), measured by RIA, in 21 asymptomatic volunteers and 26 patients with reflux esophagitis (RE) was investigated. Esophageal secretion was collected, using an esophageal perfusion catheter, during mucosal exposure to NaCl, HCl or HCl/Pepsin and final saline. The basal rate of luminal TGF alpha release in controls was steady throughout the entire four perfusion periods with saline. This rate declined by 71% during mucosal exposure to HCl (p = 0.002) and by 74% during esophageal perfusion with HCl/pepsin (p = 0.011). The basal rate of luminal TGF alpha release in patients with RE was 27% higher than the corresponding value in controls (1.076 +/- 0.140 vs. 0.850 +/- 0.180 ng/min, p = 0.050). Mucosal exposure to acid and acid/pepsin solutions in RE patients also resulted in a significant decline in the luminal release of TGF alpha by 43% (p < 0.001) and by 42% (p < 0.001) respectively. Despite this decline, TGF alpha in patients with RE was significantly higher (p < 0.001) than in controls. The decline in esophageal TGF alpha release during HCl and HCl/pepsin exposure may facilitate the development of mu...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.
