Highly Localized intracellular Ca signals promote optimal salivary gland fluid secretion.

Elife 2021 Jul 9;10. Epub 2021 Jul 9.

Pharmacology and Physiology, U. Rochester, Rochester, United States.

Salivary fluid secretion involves an intricate choreography of membrane transporters to result in the trans-epithelial movement of NaCl and water into the acinus lumen. Current models are largely based on experimental observations in enzymatically isolated cells where the Ca signal invariably propagates globally and thus appears ideally suited to activate spatially separated Cl and K channels, present on the apical and basolateral plasma membrane, respectively. We monitored Ca signals and salivary secretion in live mice expressing GCamp6F, following stimulation of the nerves innervating the submandibular gland. Read More

Yoshio Takei

Zoological Lett 2021 Jun 21;7(1):10. Epub 2021 Jun 21.

Laboratory of Physiology, Department of Marine Bioscience, Atmosphere and Ocean Research Institute, The University of Tokyo, 5-1-5 Kashiwanoha, Kashiwa, Chiba, 277-8564, Japan.

Adaptation to a hypertonic marine environment is one of the major topics in animal physiology research. Marine teleosts lose water osmotically from the gills and compensate for this loss by drinking surrounding seawater and absorbing water from the intestine. This situation is in contrast to that in mammals, which experience a net osmotic loss of water after drinking seawater. Read More

Plant Cell Physiol 2021 Jun 1. Epub 2021 Jun 1.

Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada.

Abiotic stresses such as drought result in large annual economic losses around the world. As sessile organisms, plants cannot escape the environmental stresses they encounter, but instead must adapt to survive. Studies investigating plant responses to osmotic and/or salt stress have largely focused on short-term systemic responses, leaving our understanding of intermediate to longer-term adaptation (24 h - days) lacking.

Poly(aryl cyanurate)-Based Thin-Film Composite Nanofiltration Membranes.

ACS Appl Polym Mater 2021 May 13;3(5):2385-2392. Epub 2021 Apr 13.

Films in Fluids Group-Membrane Science and Technology Cluster, University of Twente, P.O. Box 217, 7500 AE Enschede, The Netherlands.

The successful synthesis of poly(aryl cyanurate) nanofiltration membranes via the interfacial polymerization reaction between cyanuric chloride and 1,1,1-tris(4-hydroxyphenyl)ethane (TPE), atop a polyethersulfone ultrafiltration support, is demonstrated. The use of cyanuric chloride allows for the formation of a polymer that does not contain hydrolysis-susceptible amide bonds that inherently limit the stability of polyamide nanofiltration membranes. In order to achieve a thin defect-free cross-linked film via interfacial polymerization, a sufficient number of each monomer should react. Read More

AT II Receptor Blockade and Renal Denervation: Different Interventions with Comparable Renal Effects?

Kidney Blood Press Res 2021 25;46(3):331-341. Epub 2021 May 25.

Department of Department of Internal Medicine 4 (Nephrology und Hypertension), University of Erlangen, Erlangen, Germany.

Background: Angiotensin II (Ang II) and the renal sympathetic nervous system exert a strong influence on renal sodium and water excretion.
