This research assumes that a problem-solving method has an applicabdtty condmon which specifies the properties of "good" problem-dependent parameters for the method Such a condition Is used as the basis of a computer program that mechamcally generates good parameters for the method to use in solving the problem Such problem-dependent parameters for a method(More)
This paper concerns the geometric treatment of graphical models using Bayes linear methods. We introduce Bayes linear separation as a second order generalised conditional independence relation, and Bayes linear graphical models are constructed using this property. A system of interpretive and diagnostic shadings are given, which summarise the analysis over(More)
Cyclophosphamide is one of the most often used anticancer drugs. Although DNA interstrand cross-links are considered responsible for its cytotoxicity, the mechanism of initiation and execution of cell death is largely unknown. Using the cyclophosphamide analogue mafosfamide, which does not need metabolic activation, we show that mafosfamide induces(More)
Monocytes are key players in the immune system. Crossing the blood barrier, they infiltrate tissues and differentiate into (i) macrophages that fight off pathogens and (ii) dendritic cells (DCs) that activate the immune response. A hallmark of monocyte/macrophage activation is the generation of reactive oxygen species (ROS) as a defense against invading(More)
OBJECTIVE A residue-free sodium phosphate tablet (RF-NaP) was formulated that lacks microcrystalline cellulose, which can appear as a whitish residue in the colon. A multicenter, randomized, investigator-blinded study was conducted to compare the colon-cleansing efficacy of 40 or 32 tablets of RF-NaP with the marketed 40-tablet NaP treatment regimen. (More)
Immunodeficiency is a severe therapy-limiting side effect of anticancer chemotherapy resulting from sensitivity of immunocompetent cells to DNA damaging agents. A central role in the immune system is played by monocytes that differentiate into macrophages and dendritic cells (DCs). In this study we compared human monocytes isolated from peripheral blood and(More)
OBJECTIVES This study sought to evaluate the negative predictive value (NPV) of preoperative dobutamine stress echocardiography (DSE) in patients who fail to achieve target heart rate (HR) and assess the influence of resting wall motion abnormalities (WMAs) without demonstrable ischemia on perioperative events. BACKGROUND The prognostic value of a(More)
BACKGROUND To determine the maximum tolerated dose (MTD) and safety, and explore efficacy and biomarkers of vandetanib with cetuximab and irinotecan in second-line metastatic colorectal cancer. METHODS Vandetanib (an orally bioavailable VEGFR-2 and EGFR tyrosine kinases inhibitor) was combined at 100 mg, 200 mg, or 300 mg daily with standard dosed(More)
A methodology is developed for the Bayes linear adjustment of the covariance matrices underlying a multivariate constant time series dynamic linear model. The covariance matrices are embedded in a distribution-free inner-product space of matrix objects which facilitates such adjustment. This approach helps to make the analysis simple, tractable and robust.(More)
BACKGROUND Paradoxical embolization from right-to-left shunt (RLS) resulting in neurological events is well described and patients with cryptogenic neurological disease are commonly evaluated for this condition. In the course of testing for RLS by bubble contrast transcranial Doppler (TCD), we observed that some patients developed transient neurological(More)
