This study examined the extent to which lake sturgeon, Acipenser fulvescens, regulated serum ion concentrations and osmolarity in relation to ambient salinity. Twenty juvenile lake sturgeon, brood stock from the Moose River in the Hudson Bay drainage basin, were gradually transferred from freshwater to more saline waters at a rate of 2‰ day-1.

Electromagnetic Biology and Medicine, 2006 Low frequency magnetic fields have previously been shown to affect cell functions. In this article, the effects of 20 mT, 50 Hz sinusoidal magnetic field on cell proliferation, ion concentration, and osmolarity in two human cancer cell lines (HL-60 and SK-Hep-1) were investigated. Inhibition of cell growth was observed.

Clinical Radiology, 1991
Three contrast media (sodium iothalamate, iopamidol and sodium/methylglucamine ioxaglate) in a dose of 240 mg iodine per kilogram of body weight were compared in clinical urography. The ionic monomer sodium iothalamate was the only medium to significantly elevate the plasma osmolality though it returned to normal values within 4 min.

Human uterine fluid and serum, when analyzed, had the same osmolarity. Both the total cation concentration and that of albumin were lower in uterine fluid than in serum. Decreased cation concentration is probably a regulatory mechanism maintaining electroneutrality in uterine fluid when the protein concentration is decreased, since protein molecules ...

Neuroscience, 1999
The hypothalamic paraventricular nucleus, representing cell bodies in which thyrotropin-releasing hormone is synthesized, and the median eminence, representing nerve terminals, were incubated in vitro. Various hypo- and hyperosmotic solutions were tested to determine osmotic sensitivity of thyrotropin-releasing hormone secretion.

Comparative Biochemistry and Physiology Part A: Physiology, 1974
Abstract 1. 1. Hemolymph osmolarity increases more (165–208 mOsM) when the animal is rapidly dehydrated than when more slowly dehydrated (165–182 mOsM). 2. 2. Hemolymph Na + and Cl − concentrations increase with rapid dehydration but not with slow dehydration. 3. 3. Rehydration of rapidly dehydrated animals results in osmolarity and Na +

Abstract 1. 1. Blood plasma osmolarity and ion concentration, and intra-cellular fluids (muscle) were determined in juvenile toadlets in tap water, in wet soil and after dehydration of 18% body weight or following acclimatization to 400 mM/1 urea. 2. 2.
