در بخش اول این پروژه از دیدگاه مهندسی کریستال که به عنوان یک زمینه ی تحقیقاتی در حال رشد در شیمی مدرن محسوب می شود، کمپلکس های هالید جیوه (ii) با لیگاند انعطاف پذیر کربوکسامیدی (l1 = n-(2-پیرازین)-تیوفن-3– استامید) سنتز شده و ساختار کریستالی آن ها بوسیله روش پودر برای کمپلکس 2 ، [hgbr2(l1)2]، و تک کریستال برای لیگاند آزاد l1 و کمپلکس های 1، [hgcl2(l1)2] و 3، [hg2i4(l1)2]، تعیین گردید. با بررسی ...
The importance of gonadal hormones in the regulation of vascular function has been documented. An alternate and essential contribution of the sex chromosomes to sex differences in vascular function is poorly understood. We reported previously sex differences in microvessel permeability (P(s)) responses to adenosine that were mediated by the cAMP signaling pathway (Wang J, PhD thesis, 2005; Wang...
Activation of the G protein G(s) results in increases in cAMP, a necessary step in the pathway for ATP release from rabbit and human erythrocytes. In all cells, the level of cAMP is the product of its synthesis by adenylyl cyclase and its hydrolysis by phosphodiesterases (PDEs). Both iloprost (Ilo), a PGI(2) analog, and isoproterenol (Iso), a beta-agonist, stimulate receptor-mediated increases ...
cAMP regulates integrin-dependent adhesions of vascular endothelial cells (VECs) to extracellular matrix proteins, their vascular endothelial cadherin-dependent intercellular adhesions, and their proliferation and migration in response to growth and chemotactic factors. Previously, we reported that cAMP-elevating agents differentially inhibited migration of human VECs isolated from large vascul...
Cyclic nucleotide phosphodiesterase 3A (PDE3) regulates cAMP-mediated signaling in the heart, and PDE3 inhibitors augment contractility in patients with heart failure. Studies in mice showed that PDE3A, not PDE3B, is the subfamily responsible for these inotropic effects and that murine PDE3A1 associates with sarcoplasmic reticulum Ca(2+) ATPase 2 (SERCA2), phospholamban (PLB), and AKAP18 in a m...
Oxamate (OXA) is a pyruvate analogue that directly inhibits the lactate dehydrogenase (LDH)-catalyzed conversion process of pyruvate into lactate. Earlier and recent studies have shown elevated blood lactate levels among insulin-resistant and type 2 diabetes subjects and that blood lactate levels independently predicted the development of incident diabetes. To explore the potential of OXA in th...
