Introduction: Adequate levels of progesterone and efficient uteroplacental circulatory system are considered as two important factors in maintaining normal pregnancy. Conspicuously, increased vascular resistance in the uterine artery can lead to severe complications including threatened abortion by an impairment to the embryo’s blood supply. This study was conducted to determine whether vaginal...
We investigate the decays D(0)-->pi(-)l(+)nu and D(0)-->K(-)l(+)nu, where l is e or mu, using approximately 7 fb(-1) of data collected with the CLEO III detector. We find R(0) identical with B(D(0)-->pi(-)e(+)nu)/B(D(0)-->K(-)e(+)nu)=0.082+/-0.006+/-0.005. Fits to the kinematic distributions of the data provide parameters describing the form factor of each mode. Combining the form factor result...

aArg-376, bLys-155, and bArg-182 are catalytically important ATP synthase residues that were proposed to be involved in substrate Pi binding and subsequent steps of ATP synthesis [Senior, A.E., Nadanaciva, S. and Weber, J. (2002) Biochim. Biophys. Acta 1553, 188–211]. Here, it was shown using purified Escherichia coli F1-ATPase that whereas Pi protected wild-type from reaction with 7-chloro-4-n...
BACKGROUND Streptococcus pneumoniae is a common cause of bacterial keratitis, and models to examine the ocular pathogenesis of this bacterium would aid in efforts to treat pneumococcal keratitis. The aim of this study was to establish a murine model of pneumococcal keratitis. METHODS The corneas of A/J, BALB/c or C57BL/6 mice were scratched and topically infected with a clinical strain of S. ...
Persistent infection (PI) of YAC-1 cells by coxsackievirus B3 (CBV-3) was characterized. CBV-3 PIs were maintained for 7 months or more, although in two other cases cells were cured of virus at 6 and 6.5 months of PI. The titre of infectious virus peaked during the first week of the infection and then gradually decreased. The proportion of cells producing infectious centres increased to 100% by...
Role of Asn-243 in the Phosphate-binding Subdomain of Catalytic Sites of Escherichia coli F1-ATPase*
In the catalytic mechanism of ATP synthase, phosphate (Pi) binding and release steps are believed to be correlated to -subunit rotation, and Pi binding is proposed to be prerequisite for binding ADP in the face of high cellular [ATP]/[ADP] ratios. In x-ray structures, residue Asn-243 appears centrally located in the Pibinding subdomain of catalytic sites. Here we studied the role of Asn-243 in ...
Transmissible viral proventriculitis (TVP) was experimentally reproduced in 2-wk-old specific-pathogen-free chickens and commercial broiler chickens by eyedrop inoculation of adenovirus-like virus (AdLV), isolate R1 1/3. No clinical signs and no weight gain depression were observed in chickens inoculated with AdLV (R11/3); however, gross and microscopic lesions characteristic of TVP were presen...
HNK-1 carbohydrate antigen in an epitope expressed commonly in many cell surface adhesion and recognition molecules in the nervous system. We purified and characterized from rat brain a novel phosphatidylinositol (PI)-anchored 150-kD glycoprotein belonging to the HNK-1 family. The molecule (PI-GP150) was detected by combination of PI-specific phospholipase C treatment of brain membranes and Wes...
