Modulation of opioid signal transduction in SH-SY5Y neural cells by differentiating agents: Concurrent mu receptor upregulation and effector desensitization by phorbol ester
(Elsevier, 1994-02-21)
Long-term exposure of SH-SY5Y human neural cells to retinoic acid (RA) increased the binding of [3H]DAMGO and [3H]DPDPE by up to 3-fold compared to membranes of untreated cells. In contrast, incubation of the cells with ...
Expression of Wild-Type and Mutant Rat Liver CTP: Phosphocholine Cytidylyltransferase in a Cytidylyltransferase-Deficient Chinese Hamster Ovary Cell Line
(Elsevier, 1994-05)
The strain 58 Chinese hamster ovary (CHO) mutant defective in CTP:phosphocholine cytidylyltransferase was characterized as an expression system for exogenous cytidylyltransferase. Strain 58 cells express less than 5% of ...
Synthesis and assignments of regioisomeric cyanoimidazole esters
(Elsevier, 1994-02-28)
Regioassignments of ethyl cyanoimidazolecarboxylates have been performed by the nuclear Overhauser effect(NOE) studies on the regioisomeric monocyanoimidazoles obtained by the hydrolysis of the esters followed by ...
Synthesis of (+/-)tylophorine by the intramolecular cycloaddition of an azide with an [omega]-chloroalkene
(Elsevier, 1994)
Cyclization of (Z)-1-(2-chloromethyl)phenyl-5-azidopent-1-ene 10 in benzene at 120[deg]C followed by treatment with sodium borohydride produced 1,2,3,5,10,10a-hexahydropyrrolo[1,2-b]isoquinoline 11 in 71% yield. A similar ...
Thermodynamics of alkali alkanoates X. Heat capacities and thermodynamic properties of lithium methanoate and lithium ethanoate at temperatures from [approximate] 5 K to 580 K
(Elsevier, 1994-12)
Heat capacities of lithium methanoate and ethanoate (CA Registry numbers [556-63-8] and [546-89-4]) have been measured by adiabatic intermittent-heating equilibrium calorimetry from temperatures T near 5 K to 350 K and by ...
Hydrazine adsorption and decomposition on the GaAs(100)-c(8 x 2) surface
(Elsevier, 1994-12-20)
Temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), and high resolution electron energy loss spectroscopy (HREELS) have been used to study the decomposition mechanism of hydrazine (N2H4) on the ...
Slouching toward a systems approach to treatment
(Elsevier, 1994)
Both the health care sector generally and the alcohol and drug field are moving toward a truly systematic approach to treatment, accelerated by the anticipated advent of health care reform. There is considerable reluctance ...
An evaluation of the rotational barrier about the B---N bond of 1-aminoborepins
(Elsevier, 1994-04-05)
13C NMR spectroscopy has been used to determined the barriers to rotation about the B---N bonds of 1-(N-benzyl-N-methylamino)borepin and 1-(N-benzyl-N-methylamino)-4,5-dihydroborepin as 18 and 19.8 kcal mol-1, respectively. ...
Living ring opening metathesis polymerization of mesogenic norbornene derivatives
(Wiley Periodicals, Inc.Hüthig & Wepf Verlag, 1994-01)
A new class of SCLCPs was prepared by polymerizing mesogenic norbornene derivatives using Mo(CHCMe 2 R)(N‐2,6‐C 6 H 3 ‐ i ‐Pr 2 )(O‐ t ‐Bu) 2 (R = CH 3 or Ph). Monomers based on norbornene ring systems were chosen because ...
