A method for the continuous study of net water transport in the feline small bowel

A new perfusion technique has been developed for the study of net water transport across the intestinal epithelium in vivo. The lumen of an isolated intestinal segment is steadily perfused with a solution of known composition in a closed perfusion system with a reservoir large enough to prevent recirculation. The intestinal segment may be enclosed in a plethysmorgraph. Changes in the perfused volume is recorded by a volume transducer coupled to the recirculating system via a T-tube. If no motility occurs, the changes of the perfusion volume reflects net water transport across the intestinal epithelium. A quantitative comparison of this technique with the convention polyethylene glycol method revealed no significant difference. The plethysmorgraphic method also makes it possible to quantify the net water absorption via lymph and blood.

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.

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.
