Changes in fluid compartments in hamster renal papilla due to peristalsis in the pelvic wall

The pelvic peristalsis "milks" the renal papilla in rodents. This study investigates the effect of the pelvic contractions upon the fluid in papillary loops of Henle (LH) and capillaries (cap) and on the volume of collecting duct (CD) cells, papillary epithelial (PE) cells and interstitium. In the anesthetized antidiuretic hamsters the urine was made green by an intravenous infusion of lissamine green. A snare was placed loosely around the papilla. The peristalsis was recorded on a Grass recorder using a fiberoptic light signal which changed intensity with the events in the pelvis and papilla. In one group of hamsters the snare was tightened during the contraction and in another group at the beginning of the relaxation. The papilla within the pelvis was then fixed immediately. It was epon-embedded for light and electron microscopy. In the group with contracted pelvis CD, LH, and cap were all closed and empty; the papilla was elongated. In the group with relaxed pelves these structures were full and open spaces were seen between the cells of CD and PE. Morphometric measurements showed that the intercollecting duct volume was larger in the papillae with relaxed pelvis, but that cell volume of PE was larger in the papillae with co...Continue Reading

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.

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.

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.

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.


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.

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.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
