Normalization of liver glucosylceramide levels in the "Gaucher" mouse by phosphatidylserine injection
(Elsevier, 1988-04-15)
A model of the human genetic disorder, Gaucher disease, can be rapidly generated in mice by the injection of emulsified glucosylceramide and an inhibitor of the lipid's hydrolase, conduritol B epoxide. The liver grows ...
Effects of dimethyl sulfoxide on the globally ischemic heart: Possible general relevance to hypothermic organ preservation
(Elsevier, 1982-02)
Isolated perfused rabbit hearts were made globally ischemic for 2 hr, then reperfused. For 5 min before and after ischemia hearts were perfused with hypothermic (20 or 27 [deg]C), hypoxic, substrate-free cardioplegic ...
Prey selection by the copepod Diacyclops thomasi
(Springer-Verlag, 1985-03)
1. Adult females of the predaceous copepod, Diacyclops thomasi , consistently selected for the soft-bodied rotifers Synchaeta pectinata, Polyarthra major and P. remata when presented various combinations of 8 rotifer species ...
Receptor binding, antagonist, and withdrawal precipitating properties of opiate antagonists
(Elsevier, 1983-06-20)
A number of opiate antagonists and the dextro isomers of some of these drugs were studied for antagonism of acute opiate effects on ilea isolated from opiate-naive guinea pigs, precipitation of a withdrawal contraction of ...
Immunohistochemical localization of enkephalin and ACTH-related substances in the pituitary of the lamprey
(Springer-Verlag, 1984-01)
The distributions of ACTH-, αMSH-, β LPH-, and enkephalin-related substances were determined immunohistochemically in the pituitary of the brook lamprey, Lampetra lamotenii . An antiserum directed against the middle region ...
Increase in delta, but not mu, receptors in MSG-treated rats
(Elsevier, 1982-09)
Neonatal treatment of rats with Monosodium Glutamate (MSG) has been demonstrated to destroy cell bodies of neurons in the arcuate nucleus including the brain beta-endorphin (B-END) system. The effects on opiate receptors ...
Rapid expression of novel proteins in goldfish retina following optic nerve crush
(Elsevier, 1986-08-14)
SummaryPolyadenylated messenger RNA was isolated from goldfish retinas at various times following unilateral crush of the optic nerve. RNA was translated in a cell-free system and product proteins analyzed by two-dimensional ...
The effect of gentamicin on calcium uptake by renal mitochondria
(Elsevier, 1982-06-28)
The effect of the nephrotoxic aminoglycoside antibiotic, gentamicin, on calcium uptake by renal cortical mitochondria was assessed in vitro. Gentamicin was found to be a competitive inhibitor of mitochondrial Ca++ uptake. ...
Environmentally controlled phenotypic plasticity of morphology and polypeptide expression in two populations of Daphnia pulex (Crustacea: cladocera)
(Springer-Verlag, 1984-08)
Two local Daphnia pulex populations which are subject to different types of seasonally varying predation pressures were studied. Individuals from both populations were raised in laboratory environments which simulated ...
Exposure to fluctuating salinity enhances free amino acid accumulation in Tigriopus californicus (Copepoda)
(Springer-Verlag, 1988-01)
Intracellular concentrations of free amino acids (FAA) in the intertidal copepod Tigriopus californicus increase in response to hyperosmotic stress and decrease in response to hypo-osmotic stress. The purpose of this study ...
