Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles
(Academic Press Inc., 1997)
We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
Tidal-amplitude rhythms of larval release: variable departure from presumed optimal timing among populations of the mottled shore crab
(CAMBRIDGE UNIV PRESS, 2010)
It is widely assumed that optimal timing of larval release is of major importance to offspring survival, but the extent to which environmental factors entrain synchronous reproductive rhythms in natural populations is not ...
The potentiation of the histamine release induced by adenosine in mast cells from guinea pig lung and heart: Sharp dependence on the time of preincubation
(Academic Press Ltd, 2000-03-01)
We studied here the effect of a wide range of adenosine concentration and time of preincubation, on the histamine release induced in the guinea pig mast cells by different stimulus. Adenosine (10(-5)-10(-3) M) potentiated ...
The release call as a diagnostic character between cryptic related species Odontophrynus cordobae and O. americanus (Anura: Cycloramphidae)
(Magnolia Press, 2013-04)
Diploid Odontophrynus cordobae and tetraploid O. americanus are morphologically cryptic species (Martino and Sinsch 2002). These species occurs in sympatry and syntopy in the SW of the Córdoba province, Argentina (Grenat ...
The heat released during catalytic turnover enhances the diffusion of an enzyme
Recent studies have shown that the diffusivity of enzymes increases in a substrate-dependent manner during catalysis1,2. Although this observation has been reported and characterized for several different systems3–10, ...
Dynamics of Pollen Release and Stigmatic Exposure in Neotropical Piper Species: A Possible Pattern for the Genus
(Univ Chicago Press, 2018-05-01)
Premise of research.Dichogamy is a common feature in early-divergent angiosperms, as in Piper, and is related to the effectiveness of pollination. To better understand the sexual reproduction in Piper species, we determined ...
