The systemic effects of physical activity are mediated by the release IL-6 and other myokines from contracting muscle. Although muscle has been extensively studied, information on cellular mechanisms is fragmentary scarce, especially regarding role Ca2+ signals. aim this study was to characterize main components signals in human skeletal cells during secretion stimulated mobilizing agonist ATP....

Hydrolysis of ATP by partition ATPases, although considered a key step in the segregation mechanism that assures stable inheritance of plasmids, is intrinsically very weak. The cognate centromere-binding protein (CBP), together with DNA, stimulates the ATPase to hydrolyse ATP and to undertake the relocation that incites plasmid movement, apparently confirming the need for hydrolysis in partitio...

Effects of ATP and Mg2+ concentrations on bioluminescence reaction of luciferase (Photinus pyralis) were investigated by home-made luminometer. The Michaelis constants of the enzyme for ATP and Mg2+ obtained from the Lineweaver-Burk graph, were 61.9 mM ±3.3 mM and 251.6mM ± 39.0mM...

A heterogeneous particle catalyst (CuO-Fe2O3/CTS-ATP) was synthesized via injection molding and ultrasonic immersion method, which is fast effective. The applied attapulgite (ATP) wrapped by chitosan (CTS) as support, loaded dual metal oxides CuO Fe2O3 active components. After a series of characterizations catalysts, it found that were successfully evenly on the surface CTS-ATP support. used to...
