We report measurements of the branching fractions singly Cabibbo-suppressed decays $\Lambda_c^+ \to p \eta$ and \pi^0$ using full Belle data sample corresponding to an integrated luminosity 980.6 $\rm fb^{-1}$. The were collected by detector at KEKB $e^{+}$$e^{-}$ asymmetric-energy collider. A clear $\Lambda_c^+$ signal is seen in invariant mass distribution $p \eta$. yield process $7734 \pm 26...

The baroreceptor control of the sinus node was evaluated in 10 normotensive and 10 age-matched essential hypertensive subjects in whom ambulatory blood pressure was recorded intra-arterially for 24 hours and scanned by a computer to identify the sequences of three or more consecutive beats in which systolic blood pressure (SBP) and pulse interval (PI) progressively rose (+PI/+SBP) or fell (-PI/...

Food prices are expected to affect dietary intakes, however, previous findings are mixed and few are based on nationally representative data. We examined the associations of price indices of fast foods (FF-PI) and fruits and vegetables (FV-PI) with dietary intakes and BMI among U.S. children and adolescents using data from the Continuing Survey of Food Intakes by Individuals (CSFII; 1994-1998) ...

Polarization-insensitive (PI) phase-transmultiplexing (PTM) of a 10-Gb/s return-to-zero ON-OFF keying (RZ-OOK) pump and a 10-Gb/s RZbinary phase-shift keying (RZ-BPSK) probe to 20-Gb/s RZ-quadrature-PSK (RZ-QPSK) has been successfully demonstrated for the first time in a passive, birefringent AlGaAs waveguide, utilizing PI cross-phase modulation (PI-XPM). For differential QPSK (DQPSK)-detection...

The replication initiator protein pi of plasmid R6K binds seven 22 bp direct repeats (DR) in the gamma origin. The pi protein also binds to an inverted repeat (IR) in the operator of its own gene, pir, which lies outside the gamma origin sequences. A genetic system was devised to select for pi protein mutants which discriminate between IR and DR (York et al., Gene (Amst.) 116, 7-12, 1992; York ...

At rest, vascular reactivity assessed by the changes in pulsatility index (PI) is one indicator of vessel stenosis in some clinical/basic science research. However, all types of vessel stenosis do not show an alteration in the PI, because flow perfusion may be maintained by the development of collateral vessels such as in severe arterial stenosis or non-severe arterial stenosis. Therefore at re...

Bile acid transport and secretion in hepatocytes require phosphatidylinositol (PI) 3-kinase-dependent recruitment of ATP-dependent transporters to the bile canalicular membrane and are accompanied by increased canalicular PI 3-kinase activity. We report here that the lipid products of PI 3-kinase also regulate ATP-dependent transport of taurocholate and dinitrophenyl-glutathione directly in can...

Borrelia hermsii, a spirochete and an agent of relapsing fever, undergoes spontaneous antigenic variation both in vivo (1, 2) and in vitro (2). The rate of serotypic change is estimated to be 10-3-10 -4 per cell per generation (2). The antigenic repertoire of B. hermsii (2) may be as extensive as that of another vector-transmitted and blood-borne pathogen, Trypanosoma brucei, a eucaryote (3, 4)...
