Generation of 2-azapentadienyl anions and their cycloaddition with alkenes. Synthesis of 2-alkenylpyrrolidines
(Elsevier, 1994-09-19)
[alpha],[beta]-Unsaturated imines 2 bearing an N-[1-(tri-n-butylstannyl)]alkyl group were transmetalated with n-BuLi to generate 2-azapentadienyl anions 3 which underwent [4[pi]s+2[pi]s] anionic cycloadditions with alkenes ...
Phencyclidine-induced behavioral sensitization
(Elsevier, 1994-03)
Chronic administration of a psychomotor stimulant has been shown to produce progressively enhanced effects, a phenomenon called "reverse tolerance" or sensitization. The present study reexamined the effects of the daily ...
Nitric oxide: Cytokine-regulation of nitric oxide in host resistance to intracellular pathogens
(Elsevier, 1994-12-01)
To discover how nitric oxide (NO) synthesis is controlled in different tissues as cells within these tissues combat intracellular pathogens, we examined three distinctively different experimental murine models designed for ...
Effect of 2-amino oleic acid exposure conditions on the inhibition of calcification of glutaraldehyde cross-linked porcine aortic valves
(John Wiley & Sons, Inc., 1994-12)
Postimplant calcific degeneration is a frequent cause of clinical failures of glutaraldehyde cross-linked porcine bioprosthetic heart valves (BPHV). It was demonstrated previously that 2-amino oleic acid (AOA) used as a ...
Immunohistochemical localization of the kappa1 opioid receptors
(Elsevier, 1994-11-10)
Using antibodies generated to the C-terminal 41 amino acids of the cloned rat kappa receptor, the present study examines the distribution of the kappa1 receptor-like immunoreactivity (li) using immunohistochemical techniques. ...
Bone Marrow Transplantation Demonstrates That Carbonic Anhydrase II Deficiency Limited to Bone Marrow-Derived Cells Affects Ammonium Chloride Tolerance in Mice
(Elsevier, 1994-02)
Bone marrow transplantation (BMT) in mice was utilized to determine the relative importance of carbonic anhydrase II (CA II) deficiency in blood compared to kidney in the pathogenesis of the ammonium chloride intolerance ...
Cell fate and cell morphogenesis in higher plants
(Elsevier, 1994-10)
The differentiation of plant cells depends on the regulation of cell fate and cell morphogenesis. Recent studies have led to the identification of mutants and the cloning of genes that influence these processes. In several ...
The complete nucleotide sequence of cosmid vector pTL5: location and origin of its genetic components
(Elsevier, 1994-09-15)
The complete nucleotide sequence (5793 bp) of the cosmid vector pTL5 and the origin of its genetic components has been determined. Cosmid pTL5, a derivative of cosmid vector pHC79, is composed of genetic components from ...
