Acetylcholine stimulates hydrolysis of 32P-labeled phosphatidic acid in guinea pig synaptosomes
(Elsevier, 1973-02-05)
[3H]-inositol or [3H]-arachidonate was injected intracerebrally into guinea pigs. Labeled nerve endings were incubated with Ach* or CCh, both of which stimulate labeling of PhA and PhI from 32Pi by > 100% and 70% ...
Coupling of dihydroriboflavin oxidation to the formation of the higher valence states of hemeproteins
(Elsevier, 1991-11-27)
SummaryThe reactions between hydrogen peroxide and hemeproteins have been coupled to the oxidation of dihydroriboflavin so as to provide a simple method for measuring the rate constant of hemeprotein peroxidation. ...
A new 3D HN(CA)HA experiment for obtaining fingerprint H N -H α cross peaks in 15 N- and 13 C-labeled proteins
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1992-03)
A new 3D 1 H− 15 N− 13 C triple resonance experiment is presented that provides in-phase absorptive cross peaks between amide protons and α-protons of the same and the sequentially preceding residue. The experiment yields ...
Further studies on a hybrid cell-surface antigen associated with human chromosome 11 using a monoclonal antibody
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-07)
A monoclonal antibody has been obtained that recognizes an antigen encoded by human chromosome 11. We present evidence that this monoclonal antibody recognizes the same or a similar antigenic activity as that previously ...
Nuclear characteristics of cardiac myocytes following the proliferative response to mincing of the myocardium in the adult newt, Notophthalmus viridescens
(Springer-Verlag, 1988-09)
Amphibian cardiac myocytes are predominantly mononucleated and have been demonstrated to respond to injury with DNA synthesis and mitosis. The nature of this response with regard to nuclear number and ploidy is unclear. ...
Post-translational processing of gastrin in neoplastic human colonic tissues
(Elsevier, 1992-12-15)
Gastrin has been postulated to stimulate proliferation in colorectal neoplasms. Although gastrin mRNA has been demonstrated to be present in colon cancer cell lines, the intact peptide had not been recovered from human ...
Catalytic properties of the resolved flavoprotein and cytochrome B components of the NADPH dependent generating oxidase from human neutrophils
(Elsevier, 1984-01-30)
The resolved flavoprotein and cytochrome b559 components of the NADPH dependent generating oxidase from human neutrophils were the subject of further study. The resolved flavoprotein, depleted of cytochrome b559, was ...
Response of Solidago canadensis clones to competition
(Springer-Verlag, 1988-11)
Transplants of ten Solidago canadensis clones were grown under high and low competition in the field to determine whether clones differed in survival, growth, and reproduction under natural conditions. Transplants had ...
Microstructural studies of sputter-deposited TiN ceramic films
(Elsevier, 1989-05-02)
A transmission electron microscopy study was undertaken to characterize the microstructures of TiN thin films that were sputter-deposited onto Cu-Be, alumina and glass substrates. There were no substantial microstructural ...
Effects of streptozotocin-induced diabetes on feeding stimulated by centrally administered opioid agonists
(Elsevier, 1989)
The potencies of several opioid agonists are reduced in diabetic animals and in animals made hyperglycemic via injections of glucose. In this report we examined the effects of streptozotocin-induced diabetes on the feeding ...
