Using AMP deaminase (AMP aminohydrolase; EC 3.5.4.6) purified from rabbit left-ventricular heart tissue, we report direct investigation of the potential for cardiac AMP deaminase activity to be regulated by kinase-mediated phosphorylation. Rabbit heart AMP deaminase served as a substrate for Ca2+/phospholipid-dependent protein kinase (protein kinase C; PKC) exclusively; no other mammalian prote...

An extract of royal jelly (RJ) induced processes from cultured rat pheochromocytoma PC12 cells. Active components were isolated, and identified as adenosine monophosphate (AMP) and AMP N1-oxide. AMP N1-oxide was more than 20 times as active as AMP, judging from the minimal concentration to elicit activity. AMP N1-oxide was thought to be responsible for about half of the process-forming activity...

Periodic activities of Dictyostelium discoideum cells involve two types of oscillations, spike-shaped and sinusoidal. Spike-shaped oscillations are accompanied by the periodic synthesis and release of cyclic AMP, and cyclic AMP-activated cyclic AMP synthesis is believed to control these oscillations. Experiments described here call into question the importance of cyclic AMP in spike-shaped osci...

1. The present study extends the finding of Krebs & Woodford (1965) that muscle fructose diphosphatase is more sensitive to AMP inhibition than liver fructose diphosphatase. 2. Hen breast fructose diphosphatase has a K(i) for AMP of 0.1mum; the plot of percentage inhibition is non-sigmoid and the reciprocal plot of activity against AMP concentration is sometimes linear. 3. Percentage inhibition...

Monsters are commonly stereotyped as horrible and grotesque creatures. But in Frankenstein The Island of Doctor Moreau, Shelly Wells both delineate some complicated but meaningful monster characters. These monsters’ features natures represent their creator’s intention purpose. In texts, monsters ugly benevolent, while creators eccentric monstrous. relationship between men allows us to view the ...

In this paper, we construct a general model for pension fund when there are time delays in the valuation process. Actually, use standard structure of basic reserve equation order to rebuild more sophisticated approach based on theory H∞ control. Our evaluates incomplete information from delayed valuations—due oscillatory pattern benefit claims and investment experience past years—within context...

The superconductivity in (NbTa)1-X(HfZrTi)X high-entropy alloy is analyzed using the theory of strong-coupled superconductor. It concluded that a strong coupled variation superconducting transition temperature from 7.9 K to 4.6 as x increases 0.2 0.84 arises because decrease electronic band width due localization and broadening band. suggested crystalline randomness which gives rise mobility ed...

We use a nuclear technique based on the determination of detection efficiencies solid state track detectors CR-39 and LR-115 type II (SSNTDs) for alpha particles emitted from series uranium-238 thorium-232 in phytotherapeutic sample measurement densities registered these to assess activities due uranium-238; thorium-232; radon thoron samples preparations consumed by Moroccan adult patients. For...

Abstract. Deglaciations are characterized by the largest natural changes in methane (CH4) and nitrous oxide (N2O) concentrations of past 800 000 years. Reconstructions millennial- to centennial-scale variability within these periods mostly restricted last deglaciation. In this study, we present composite records CH4 N2O from EPICA Dome C ice core covering penultimate deglaciation at temporal re...
