The chemical synthesis of 2-keto-3-deoxy-octonate and its cleavage by a specific aldolase
(Elsevier, 1963-05-22)
We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate (KDO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of 0111-B4 and the enzymatic synthesis ...
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% ...
Assessing environmental impact on mass balance, carrying capacity and growth of exploited populations
(Elsevier, 1984)
Population models that have been applied for assessment of exploited populations are also useful for assessment of environmental impacts. Surplus production models have been applied for both fishery and environmental impact ...
Detection of intermediate protein conformations by room temperature tryptophan phosphorescence spectroscopy during denaturation of Escherichia coli alkaline phosphatase
(Elsevier, 1993-12)
The reversible denaturation of Escherichia coli alkaline phosphatase (AP) was followed by monitoring changes in enzymatic activity as well as by measurements of the time-resolved room temperature phosphorescence from Trp ...
Discovery of the Northeast Passage: the voyage of the VEGA, 1878–1879
(Kluwer Academic Publishers; Akademische Verlagsgesellschaft ; Springer Science+Business Media, 1979-07)
The gravity reference response, the rotation sensation, and other illusory sensations experienced in aircraft and space flight
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1973-09)
An analysis of the gravitational and inertial forces which act during aircraft flight upon the vestibular systems of the aircraft occupants reveals that in the absence of a visual horizon, certain illusory sensations are ...
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 ...
Electroantennogram responses of Hyles lineata (Sphingidae: Lepidoptera) to volatile compounds from Clarkia breweri (Onagraceae) and other moth-pollinated flowers
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1996-10)
Electroantennograms (EAGs) from field-collected Hyles lineata moths were recorded in response to 10 individual floral volatiles identified from Clarkia breweri (Onagraceae), to 22 scent compounds produced by other ...
