Molecules of 5-methyl-2-phenyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C21H17N3, (I), are linked into chains by a combination of a C-H...pi(arene) hydrogen bond and a pi-pi stacking interaction; in the closely related 5-methyl-2-(4-methylphenyl)-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C22H19N3, (II), there are no hydrogen bonds and the molecules are linked into centrosymmetric dim...

We study $D_{s}^{+}\to\rho^{0(+)}a^{+(0)}_{0}$, $D_{s}^{+}\to\omega a^{+}_{0}$, and the resonant $D_{s}^{+}\to\rho a_0$,$a_{0}\to \eta\pi(KK)$ decays. In final state interaction, where $D_s^+\to (\eta^{(\prime)}\pi^+,K^+\bar K^0)$ are followed by $(\eta^{(\prime)}\pi^+,K^+\bar to $\rho^{0(+)}a^{+(0)}_{0}$ rescatterings, we predict ${\cal B}(D_{s}^{+}\to\rho^{0(+)}a^{+(0)}_{0})=(3.0\pm 0.3\pm 1....

This paper serves as an update of the previous work entitled ``Heavy-Flavor-Conserving Hadronic Weak Decays Charmed and Bottom Baryons". We make improvement on bag wave functions by removing center-of-mass motion bag. All baryon matrix elements are now calculated under same framework without introducing new parameters. The 4-quark operators found to be nearly twice larger than ones. branching f...

The effects of aldosterone on the intracellular pH recovery rate (pHirr) via Na+/H+ exchanger and on the [Ca2+]i were investigated in isolated rat S3 segment. Aldosterone [10(-12), 10(-10), or 10(-8) M with 1-h, 15- or 2-min preincubation (pi)] caused a dose-dependent increase in the pHirr, but aldosterone (10(-6) M with 1-h, 15- or 2-min pi) decreased it (these effects were prevented by HOE694...

In order to track the evolution of primary protease inhibitor (PI) resistance mutations in human immunodeficiency virus type 1 (HIV-1) isolates, baseline and follow-up protease sequences were obtained from patients undergoing salvage PI therapy who presented initially with isolates containing a single primary PI resistance mutation. Among 78 patients meeting study selection criteria, baseline p...

In the present work, we investigate several theoretical models of pion vector form factor and aim at getting best fit for two-pion cross sections to reduce uncertainties calculation contribution muon anomalous magnetic moment. Combined with a polynomial description factor, obtain from Gounaris-Sakurai (or K\"uhn-Santamaria) model experimental data up 1 GeV. By product, branching ratio $\omega \...

BACKGROUND A preanesthetic visit can increase a patient's satisfaction. However, it is uncertain whether a preanesthetic visit by an anesthesiology resident can achieve the goal. We studied the time distribution for content of preanesthetic interviews (PI) and evaluated the patient's satisfaction with the PI. METHODS We recorded the PI duration of 200 patients by a voice recorder. The degrees...

ATPase activity and ATP-Pi exchange of unregulated (without tropomyosin-troponin) and regulated (with tropomyosin-troponin) acto-HMM were measured in media containing 0.2 mg/ml actin, HMM, and (when present) tropomyosin-troponin, 2 mM MgCl2, 10 mM KCl, 2 mM NaN3, 10 mM Pi (pH 7.0), 3 MM ATP. The following mean values for ATPase activity and for the rate of incorporation of Pi into ATP (each per...

BACKGROUND Brecanavir, a novel protease inhibitor (PI), has sub-nM in vitro antiviral activity against multi-PI-resistant HIV-1 and in vitro is >100-fold more potent than previously marketed PIs and approx. 10-fold more potent than the recently marketed PI, darunavir. METHODS HPR10006 is an open label, single-arm, descriptive 48 week study, with 8 and 24 week interim analyses. Thirty-one HIV-...

We present the first measurement of branching fraction singly Cabibbo-suppressed (SCS) decay $\Lambda_c^+ \to p \eta'$ with $\eta' \eta\pi^+\pi^-$, using a data sample corresponding to an integrated luminosity 981 $\rm fb^{-1}$, collected by Belle detector at KEKB $e^{+}$$e^{-}$ asymmetric-energy collider. A significant $\Lambda_c^+$ signal is observed for time significance 5.4$\sigma$. The rel...
