Thermodynamic properties of tungsten ditelluride (WTe2) I. The preparation and lowtemperature heat capacity at temperatures from 6 K to 326 K
(Elsevier, 1992-06)
The heat capacity of the dichalcogenide: tungsten ditelluride, WTe2, was measured over the temperature range 5.5 T/K Cp m occurs in the region 92 T/K Sm = (0.10±0.02) · R. The anomaly coincides with the ...
Effects of Mild Hypothermia on the Release of Regional Glutamate and Glycine During Extended Transient Focal Cerebral Ischemia in Rats
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-07)
The present study is to determine the effect of mild hypothermia (MHT) on the release of glutamate and glycine in rats subjected to middle cerebral artery occlusion and reperfusion. The relationship between amino acid ...
Nucleotide sequence and expression of the mouse corticotropin-releasing hormone gene
(Elsevier, 1991-06)
The mouse corticotropin-releasing hormone (CRH) gene has been isolated and characterized by DNA sequence analysis. The gene exhibits a structural organization similar to that of the human, rat, and ovine genes with two ...
Quantitative in vivo receptor binding IV: Detection of muscarinic receptor down-regulation by equilibrium and by tracer kinetic methods
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-09)
Newly-developed methods for estimation of in vivo binding to neurotransmitter receptors should enable the detection and quantification of physiologic or pathologic changes in receptor numbers. In the present study, both ...
Affinity of the antiviral enantiomers of oxathiolane cytosine nucleosides for human 2'-deoxycytidine kinase
(Elsevier, 1993-04-06)
The two enantiomers of 2',3'-dideoxy-3'-thiacytidine (BCH-189) and their 5-fluoro analogs (FTC) were found to be good substrates for human 2'-deoxycytidine kinase with Km values in the 5.7 to 42.1 [mu]M range. The affinity ...
Formation of a toxic metabolite from gentamicin by a hepatic cytosolic fraction
(Elsevier, 1992-04-15)
We have demonstrated recently that incubation of the aminoglycoside gentamicin with an hepatic post-mitochondrial fraction produces a compound toxic to sensory cells from the inner ear in short-term culture; in contrast, ...
Specific steroid response from a nonspecific DNA element
(Elsevier, 1994-06)
A fundamental dilemma of steroid hormone regulation is how specific transcription is attained in vivo when several receptors recognize the same DNA sequence in vitro. We have identified an enhancer of the mouse sex-limited ...
Dinucleotide polymorphism at the DXS1178 locus is tightly linked to PGK1 at Xq13
(Springer-Verlag, 1995-04)
A polymorphic CA repeat (locus name DXS1178 ) was isolated from a 1-megabase YAC (OTCC) containing the OTC gene, located at Xp21.1. However, amplification in human-rodent hybrid cells and segregation analysis in three CEPH ...
Enzymatic synthesis of sialyl Lex and derivatives based on a recombinant fucosyltransferase
(Elsevier, 1991)
A recombinant human Lewis [alpha](1,3/1,4)fucosyltranferase has been studied for its acceptor substrate specificity and used in the synthesis of sialyl Lex and derivatives.
