Cougnon, Marc, Patrice Bouyer, Frédéric Jaisser, Aleksander Edelman, and Gabrielle Planelles. Ammonium transport by the colonic H1-K1-ATPase expressed in Xenopus oocytes. Am. J. Physiol. 277 (Cell Physiol. 46): C280–C287, 1999.—Functional expression of the rat colonic H1-K1-ATPase was obtained by coexpressing its catalytic a-subunit and the b1-subunit of the Na1-K1-ATPase in Xenopus laevis oocy...
We present a calculation of the two-loop anomalous dimension for the transversity distribution h1(x,Q ), γ n , in the MS scheme of the dimensional regularization. Because of the chiral-odd nature, h1 does not mix with the gluon distributions, and thus our result is the same for the flavor-singlet and nonsinglet distributions. At small n (moment of h1), γ h(1) n is significantly larger than γ n ...
A newly identified costimulatory molecule, programmed death-1 (PD-1), provides a negative signal that is essential for immune homeostasis. However, it has been suggested that its ligands, B7-H1 (PD-L1) and B7-dendritic cells (B7-DC; PD-L2), could also costimulate T cell proliferation and cytokine secretion. Here we demonstrate the involvement of PD-1/B7-H1 and B7-DC interaction in the developme...
In certain Ras mutant cell lines, the inhibition of extracellular signal-regulated kinase (ERK) signaling increases RhoA activity and inhibits cell motility, which was attributed to a decrease in Fra-1 levels. Here we report a Fra-1-independent augmentation of RhoA signaling during short-term inhibition of ERK signaling. Using mass spectrometry-based proteomics, we identified guanine exchange f...
A chromatin associated protein kinase was used to add 3 moles of phosphate to seryl side chains of 1 mole of histone H1. The DNA binding properties of this in vitro phosphorylated H1 were compared with those of unmodified H1. Considerably more radioactive superhelical DNA was retained on nitrocellulose filters at 20mM-40mM NaCl by phosphorylated H1 than by unmodified H1. However, zone velocity ...
این مقاله به بررسی همبسته های ادراکی کشش جبرانی در زبان فارسی میپردازد. در یک آزمایش ادراکی، درک شنیداری کشش جبرانی از طریق تغییر مقادیر دیرش واکه، اختلاف دامنه 2 h1-h و h1-f1 و بسامد پایه مطابق با نتایج آزمایش تولیدی صادقی (2007) مورد بررسی قرار گرفت. نتایج نشان داد تغییرات دیرش واکه اصلیترین نشانة ادراکی کشش واکه است و عوامل دیگر مانند اختلاف دامنه h1-h2 و h1-f1 و فرکانس پایه بر درک کشش واکه...
Let M be an compact orientable 3 manifold whose boundary ∂M consists of a single torus. If a meridian and longitude in this torus are chosen, then isotopy classes of smoothly embedded circles in ∂M that do not bound disks correspond bijectively with elements of QP = Q ∪ {1/0} , regarded as slopes of these curves. We show in this paper that the set of slopes coming from boundary curves of incomp...
BACKGROUND Calponin h1, a basic actin-binding protein capable of inhibiting smooth muscle contraction, is a constitutive element of smooth muscle cells. However, in leiomyosarcoma (a type of smooth muscle neoplasm of the uterus), reduced expression of calponin h1 is observed, as we have reported previously. In this study, we sought to assess the effects (in vitro and in vivo) of increasing calp...
واکنش الیفیناسیون پترسون ترفتالدهید با تریس(تری متیل سیلیل)متیل لیتیم در اتر، 4- [2و2- بیس (تری متیل سیلیل)اتنیل] بنز آلدهید (1) را می دهد که می توانددر سنتز تترازول های جدید با استفاده از واکنش شبه یوگی مورد استفاده قرار گیرد( ugi-4cc). این واکنش یک واکنش ساده وتک ظرفی مناسب می باشد که برای سنتز مشتقات تترازول های جدید حاوی گروه های ارگانو سیلیکون با استفاده از آلدهید (1)، آمین های مختلف ، تر...
The data presented in this article are related to the research article entitled "Quantitative determination of linking number differences between circular polynucleosomes and histone H1-bound circular polynucleosomes" Zhang et al. (in press) [1]. DNA linking number differences between histone H1-free and histone H1-bound circular polynucleosomes at various spermidine concentrations was quantita...
