Vascular endothelial growth factor (VEGF) plays a crucial role in angiogenesis and in pathological processes such as tumor growth, rheumatoid arthritis, and ocular neovascularization. A recombinant humanized monoclonal antibody (rhuMAb), rhuMAb VEGF, has been developed to inhibit the effects of VEGF in the treatment of solid tumors. Intravenous and s.c.(More)
ISSUE The Asia Pacific Economic Cooperation (APEC) has undertaken an initiative in emerging infections. PROJECT The APEC Emerging Infections Network project uses collaborative telecommunications tools such as e-mail and a World Wide Web site to bridge the broad geographic expanse and diversity of APEC. Scientists and policymakers share information to(More)
1. The role of chloride concentration in modulating vasoconstrictor responses of the rat isolated kidney, perfused with Krebs-Henseleit solution, to angiotensin II (AII), arginine vasopressin (AVP) and phenylephrine (PE) was investigated. 2. Reduction of perfusate chloride from a high (117 mM) to low (87 mM) concentration, by substitution of sodium chloride(More)
This study provides an attempt to use the extracellular metabolites of a dye-decolorizing strain, Escherichia coli strain NO3, as a biostimulator to entice E. coli strain NO3 into a beneficial mode of metabolism for an economically feasible decolorization. Addition of supernatants containing metabolites from growth and decolorization cultures triggered an(More)
We report a highly sensitive method to detect rare human breast cancer cells, which combines an immunomagnetic separation (IMS) using antibody BM2 against MUC-1 with cytokeratin-19 (CK19) and the reverse transcriptase/polymerase chain reaction (RT-PCR). The IMS-RT-PCR technique allows the detection of 1 tumor cell/107–108 mononuclear cells. This is at least(More)
Several actions of angiotensin II have been linked to metabolism of arachidonic acid by lipoxygenases. To evaluate the importance of this interaction intrarenally we tested the effect of three different lipoxygenase inhibitors, BW755c (50 microM), a dual lipoxygenase-cyclooxygenase inhibitor, MK447 (200 microM), a nonselective lipoxygenase inhibitor which(More)
We describe a method for measuring Ro 48-3656 in EDTA rat plasma by neutral pH, reversed-phase high-performance liquid chromatography using a 1.5-microm nonporous silica, C18 analytical column and UV absorbance detection to support pharmacokinetic studies. We also describe a comparison of the 1.5-microm nonporous silica C18 column versus 3.5-microm porous(More)
This study characterized the pharmacokinetics (PK) and pharmacodynamics (PD) of sibrafiban (Ro 48-3657) in the presence of aspirin, heparin, and recombinant tissue-type plasminogen activator (rt-PA) in beagles. Sibrafiban is a double prodrug that undergoes bioconversion to the inactive prodrug Ro 48-3656 and to the active IIb/IIIa antagonist, Ro 44-3888,(More)
ADP-glucose pyrophosphorylase (ADPGlc PPase, EC from Rhodobacter sphaeroides 2.4.1 has been purified to near homogeneity. The enzyme reacted in Western blots to polyclonal antibodies raised against other bacterial ADPGlc PPases. The purified enzyme was found to be activated by fructose 6-phosphate, fructose 1,6-bisphosphate, and pyruvate and(More)
