Abstract:
Preequilibration at 37 degrees C in isosmotic media with Cl replaced by lyotropic (foreign) anions reversibly increased Cl-dependent K efflux and Rb influx, the inhibition by furosemide, and thus K-Cl cotransport in low-K but not in high-K sheep erythrocytes with the following order of effectiveness: SCN greater than I greater than NO3 greater than Cl = Br. This effect depended on time, temperature, and anion concentration and was reversible. Preincubation in isosmotic SCN at 37 degrees C stimulated K-Cl flux in anisosmotic Cl media (370-240 mosM) by increasing the volume sensitivity through s

Abstract:
Teleost fish growth may be improved under isosmotic condition. Growth and metabolic performance of juvenile Mugil liza (isosmotic point: 12‰) were evaluated after 40 days in different salinities (0, 6, 12 and 24‰). Tests were performed in quadruplicate (30 fish/tank; 0.48 ± 0.1 g body weight; 3.27 ± 0.1 cm total length) under controlled water temperature (28.2 ± 0.1ºC) and oxygen content (>90% saturation). Fish were fed on artificial diet (50% crude protein) four times a day until apparent satiation. Results showed that salinity influenced juvenile mullet growth. Fish reared at salinity 24‰

Abstract:
Rainbow smelt, Osmerus mordax, have previously been shown to produce high concentrations of glycerol in winter to avoid freezing, becoming almost isosmotic in a marine environment when temperatures reach the freezing point of seawater. Here it is shown that osmotic water losses, as shown by drinking rate, decrease dramatically in winter as a result of the increased osmolality. Urine flow also appears to decrease in winter in response to reduced drinking. Glycerol is lost through the skin and gills, and probably through intestinal discharge, at total rates ranging from 3.5 to 9.5 mg∙100 g−1∙h−1

Abstract:
Osmotic costs in teleosts are highly variable, reaching up to 50% of energy expenditure in some. In several species, environmental salinities close to the isosmotic point (~15 psu) minimize energy demand for osmoregulation while enhancing growth. The present study aimed to characterize the physiological status related to osmoregulation in early juveniles of the greater amberjack, Seriola dumerili, acclimated to three salinities (15, 22, and 36 psu). Our results indicate that plasma metabolic substrates were enhanced at the lower salinities, whereas hepatic carbohydrate and energetic lipid subs

Abstract:
Okapi would benefit from artificial insemination with frozen-thawed sperm in cases where aggression prevents mating or where individuals are geographically disparate. Effective sperm cryopreservation is a prerequisite to this goal. Ejaculates (n = 20) were collected from 7 anesthetized adult male okapi housed individually, or with a female for breeding, throughout the year by electroejaculation, and semen and sperm parameters were assessed. Semen aliquots were centrifuged; resuspended in 500 µL of PBS with the osmolarity adjusted to 35, 75, 150, 600, 1200, and 2400 mOsm; and incubated for 30 m

Abstract:
Pore network modeling based on digital rock is employed to evaluate the mobility of shale oil in Qingshankou Formation, Songliao Basin, China. Computerized tomography technology is adopted in this work to reconstruct the digital rock of shale core. The pore network model is generated based on the computerized tomography data. We simulate the dynamics of fluid flow in a pore network model to evaluate the mobility of fluid in shale formation. The results show that the relative permeability of oil phase increases slowly in the initial stage of the displacement process, which is mainly caused by t

Survival and physiological parameters associated with metabolism and osmoregulation were evaluated in juveniles of the Lebranche mullet Mugil liza acclimated to different water salinities (5, 10, 20, 30, and 40‰) for 15 days. Room temperature (25ºC) and photoperiod (12L:12D) were fixed. Fish were fed twice-a-day with commercial diet (28% crude protein) until satiation. After acclimation, whole body oxygen consumption was measured and fish were euthanized and sampled for blood, gills, and liver.

Renal clearance studies were performed on anesthetized sea snakes (Aipysurus laevis) under various salt and volume loads. The median values for the control glomerular filtration rate (GFR) and urine flow rate (V) were 0.78 and 0.11 ml X kg-1 X h-1, respectively. Acute salt loading with 1 mol/l NaCl significantly increased V to 0.68 ml X kg-1 X h-1, whereas acute water loading significantly decreased GFR to 0.17 ml X kg-1 X h-1. Acute loading with either isosmotic NaCl or seawater did not significantly alter either V or GFR. Chronic loading with water or seawater by intraperitoneal injection si

Abstract:
In several tissues, transient receptor potential vanilloid 4 (TRPV4) channels are involved in the response to hyposmotic challenge. Here we report TRPV4 protein in porcine lens epithelium and show that TRPV4 activation is an important step in the response of the lens to hyposmotic stress. Hyposmotic solution (200 mosM) elicited ATP release from intact lenses and TRPV4 antagonists HC 067047 and RN 1734 prevented the release. In isosmotic solution, the TRPV4 agonist GSK1016790A (GSK) elicited ATP release. When propidium iodide (PI) (MW 668) was present in the bathing medium, GSK and hyposmotic s
