in this paper, at first we introduce a new index with the name co-pi index and obtain someproperties related this new index. then we compute this new index for tuc4c8(r) nanotubes.

The goal of this project was to isolate representative Fe(III)-reducing bacteria from kaolin clays that may influence iron mineralogy in kaolin. Two novel dissimilatory Fe(III)-reducing bacteria, strains G12(T) and G13(T), were isolated from sedimentary kaolin strata in Georgia (USA). Cells of strains G12(T) and G13(T) were motile, non-spore-forming regular rods, 1-2 mum long and 0.6 mum in dia...

We demonstrated recently that norepinephrine activates Ca2+ -permeable nonselective cation channels (NSCCs) in Chinese hamster ovary cells stably expressing alpha1A-adrenergic receptors (CHO-alpha1A). Moreover, extracellular Ca2+ through NSCCs plays essential roles in norepinephrine-induced arachidonic acid release. The purpose of the present study was to identify the G proteins involved in the...

Regulation of multiple adenylyl cyclases (AC) provides unique inputs to mediate the synthesis of cAMP, a ubiquitous second messenger that controls many aspects of cellular function. On stimulation by Gs, the activities of ACs can be further selectively modulated by other pathways to ensure precise control of intracellular cAMP responses to specific stimuli. Recently, we reported that one of the...

The G12 subfamily of heterotrimeric G-proteins consists of two members, G12 and G13. Gene-targeting studies have revealed a role for G13 in blood vessel development. Mice lacking the subunit of G13 die around embryonic day 10 as the result of an angiogenic defect. On the other hand, the physiological role of G12 is still unclear. To address this issue, we generated G 12-deficient mice. In contr...
