The obestatin/ghrelin system as a novel regulatory mechanism of iris muscle contraction.
PURPOSE To evaluate obestatin and ghrelin effects on iris muscle contraction. MATERIALS AND METHODS Obestatin (10(-5) M) or ghrelin (10(-5) M) were tested on two consecutive carbachol-or epinephrine-elicited contractions of iris rabbit sphincter or dilator muscles. Ghrelin and obestatin effects on iris muscles basal tension were also tested, and their effects on iris sphincter EFS-elicited co...
متن کاملwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

15 صفحه اولCalcium ion-insensitive contraction of glycerinated porcine cardiac muscle fibers by Mg-inosine triphosphate. ITP as a tool to dissociate the contraction mechanism from the regulatory mechanism.
The contraction of cardiac muscle that has been treated with glycerol requires Ca2+ (pCa 8-5), when MgATP is used as a substrate. In contrast, this preparation contracts, even in the absence of Ca2+ (pCa 8-10), when ATP is replaced by ITP. Ca2+ dependency was not observed after increasing free Ca2+ concentrations from pCa 8.0 to 5.0, or after increasing MgITP concentration from 5 to 80 mM. On t...

The contraction of cardiac muscle that has been treated with glycerol requires Ca (pCa 8-5), when MgATP is used as a substrate. In contrast, this preparation contracts, even in the absence of Ca (pCa 8-10), when ATP is replaced by ITP. Ca dependency was not observed after Increasing free Ca concentrations from pCa 8.0 to 5.0, or after increasing MgTTP concentration from A to 80 mM. On the other...
