BACKGROUND Elevated heart rate is associated with increased cardiovascular morbidity. The selective I(f) current inhibitor ivabradine reduces heart rate without affecting cardiac contractility, and has been shown to be cardioprotective in the failing heart. Ivabradine also exerts some of its beneficial effects by decreasing cardiac proinflammatory cytokines and inhibiting peroxidants and collag...

Given the importance of auxin, it has been surprisingly difficult to elucidate its biosynthetic pathways in plants. Several Trpdependent routes have been proposed, in which CYTOCHROME P450 79B2/B3 (CYP79B2/B3), YUCCA (YUC), and TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS1/TRYPTOPHAN AMINOTRANSFERASE RELATED (TAA1/TAR) genes have been thought to act in separate pathways (reviewed in Zhao, 2010). ...

One dairy goat herd of mixed breeds was investigated for frequency of genetic variants of alphas1-casein (as1-CN) and relationships between the genetic variants, milk composition, coagulation properties, and breed. Milk composition (percent total solids, solids-non-fats (SNF), fat, protein, casein, and as1-CN), genetic variants of as1-CN, and coagulation properties (coagulation time, coagulatio...

The insulin release enhancer, 10-hydroxy-11,12-trans-epoxy-5(Z),8(Z),14(Z)-icosatrienoic acid (hepoxilin B3), is a 12-lipoxygenase metabolite of arachidonic acid that has been found in various mammalian tissues. Although lipoxygenase pathways are well documented in terrestrial plants, this lipoxygenase product has never been isolated from the plant kingdom. Herein, we report the first isolation...

OBJECTIVE To study bone mineral density (BMD) in adolescent females according to five groups of chronological age (CA), bone age (BA), and breast development stage (B), and to correlate these parameters with plasma bone biomarkers (BB). METHODS This was a cross-sectional study performed in 101 healthy adolescent females between 10 and 20 years old. The study variables were: weight, height, bo...

We extend the well-known notions of ambiguity and of degrees of ambiguity of 0nitary context free languages to the case of omega context free languages (!-CFL) accepted by B3 uchi or Muller pushdown automata. We show that these notions may be de0ned independently of the B3 uchi or Muller acceptance condition which is considered. We investigate 0rst properties of the subclasses of omega context ...

UNLABELLED The aim of this study was to determine if pulsed high-intensity focused ultrasound (HIFU) exposures could enhance tumor uptake of (111)In-MX-B3, a murine IgG1kappa monoclonal antibody directed against the Le(y) antigen. METHODS MX-B3 was labeled with (111)In, purified, and confirmed for its binding to the antigen-positive A431 cell line. Groups of nude mice were inoculated subcutan...

this study was conducted to investigate the effect of physical and chemical processing on crude protein fractions of two varieties of canola (okapi and modena) and safflower (62 and zarfan) seed using cornel net carbohydrate and protein system and on protein subunits using sodium dodecyl sulfate polyacrylamide gel electrophoresis. formaldehyde was used as chemical treatment, while toasting and ...

The four encapsidated RNAs of brome mosaic virus (BMV; B1, B2, B3, and B4) contain a highly conserved 3' 200-nucleotide (nt) region encompassing the tRNA-like structure (TLS) which is required for packaging in vitro (Y. G. Choi, T. W. Dreher, and A. L. N. Rao, Proc. Natl. Acad. Sci. USA 99:655-660, 2002). To validate these observations in vivo, we performed packaging assays using Agrobacterium-...
