Assessment of ultrastructure in isolated cochlear hair cells using a procedure for rapid freezing before freeze-fracture and deep-etching
(Kluwer Academic Publishers; Chapman and Hall Ltd ; Springer Science+Business Media, 1991-06)
Separated cochlear outer hair cells and isolated strips of organ of Corti containing hair cells and supporting cells have been rapidly frozen before freeze-fracture and deep-etching by immersion of samples sandwiched between ...
Ca2+-independent regulation of neurosecretion by intracellular Na+
(Elsevier, 1991-11-04)
While secretion from nerve endings is strictly controlled by an increase in cytoplasmic free calcium several reports suggest intracellular sodium may serve a regulatory role. Whether sodium acts directly to modulate secretion ...
Inheritance of isozyme and RFLP markers in Brassica campestris and comparison with B. oleracea
(Springer-Verlag, 1991-10)
Using primarily cDNA restriction fragment length polymorphism markers (RFLPs) previously located to Brassica oleracea (cabbage, 2n=18) chromosomes, we initiated a comparative RFLP map in an F 2 population of B. campestris ...
Ornithine decarboxylase activity during development of the mouse inner ear in vivo and in vitro
(Springer-Verlag, 1991-09)
Ornithine decarboxylase activity was determined during the development of the peripheral auditory system in the murine otocyst with the goal of understanding the role of this enzyme in the morphological and functional ...
Evidence that the protein components of bovine erythrocyte green heme binding protein and flavin reductase are identical
(Elsevier, 1991-07-15)
Bovine erythrocyte green heme binding protein and bovine erythrocyte flavin reductase have been isolated in highly purified forms and subjected to amino acid analysis and N-terminal amino acid sequence analysis. The two ...
Mastoparan induces oscillations of cytosolic Ca2+ in rat pancreatic acinar cells
(Elsevier, 1991-05-31)
Microfluorimetry of fura-2 was used to monitor [Ca2+]i in single cells stimulated with the G-protein activating agent mastoparan. Mastoparan induced the generation of [Ca2+]i oscillations, which in contrast to oscillations ...
Zooplankton spine induces aversion in small fish predators
(Springer-Verlag, 1991-11)
The spined cladoceran Bythotrephes cederstroemi is protected from small fish predators due to the difficulty small fish have in ingesting the spine. Juvenile yellow perch (Perca flavescens) 50–60 mm in length were offered ...
Starvation resistance of gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae): tradeoffs among growth, body size, and survival
(Springer-Verlag, 1991-11)
Survival and body composition of starving gypsy moth larvae initially reared on aspen foliage or artificial diet differeing in nitrogen (N) and carbohydrate concentration were examined under laboratory conditions. Diet ...
Manganese superoxide dismutase from Thermus thermophilus: A structural model refined at 1.8 A resolution
(Elsevier, 1991-05-20)
The structure of Mn(III) superoxide dismutase (Mn(III)SOD) from Thermus thermophilus, a tetramer of chains 203 residues in length, has been refined by restrained least-squares methods. The R-factor (= [summation ...
Characterization of glucagon-like peptide-I(7-36)amide receptors of rat lung membranes by covalent cross-linking
(Elsevier, 1991-03-25)
125I-labelled GLP-I(7-36)amide was cross-linked to a specific binding protein in rat lung membranes using disuccinimidyl suberate. A single radio-labelled band at Mr 66000 was identified by SDS-PAGE after solubilization ...
