Alternative graft sources (umbilical cord blood [UCB], matched unrelated donors [MUD], or mismatched unrelated donors [MMUD]) enable patients without a matched sibling donor to receive potentially curative hematopoietic cell transplantation (HCT). Retrospective studies demonstrate comparable outcomes among different graft sources. However, the risk and types of infections have not been compared...
In this paper we propose and explore the k-Nearest Neighbour UCB algorithm for multiarmed bandits with covariates. We focus on a setting where the covariates are supported on a metric space of low intrinsic dimension, such as a manifold embedded within a high dimensional ambient feature space. The algorithm is conceptually simple and straightforward to implement. The k-Nearest Neighbour UCB alg...
Results of previous studies have suggested that UCB (unconjugated bilirubin) may be transported by MRP1/Mrp1 (multidrug-resistance-associated protein 1). To test this hypothesis directly, [3H]UCB transport was assessed in plasma-membrane vesicles from MDCKII cells (Madin-Darby canine kidney II cells) stably transfected with human MRP1 or MRP2; wild-type MDCKII cells served as controls. As revea...
The rate of peroxidation of unbound, unconjugated bilirubin (UCB) was used to assess the interactions of UCB with four taurine-conjugated bile salts at pH 8.2, 37 degrees C, and an ionic strength of 0.15. Each of the four structurally different bile salts markedly decreased the rate of peroxidation of UCB in the presence of horseradish peroxidase (HRP); 30% of UCB was bound even at low, premice...
Much of our work has focused on the design and implementation of a Unix Consultant (UC) program. This system carries out a dialog in English to answer user 's queries about the UNIX operating system. UC comprises a natural language parsing and generation system, a goal analyzer that hypothesizes user 's goals in different contexts, a user model component that allows UC to tailor answers to the ...
Umbilical cord blood (UCB) stem cells from related and unrelated allogeneic donors have emerged as novel treatment for patients with hematologic malignancies. The incidence and severity of acute graft-versus-host disease (GVHD) after UCB transplantation compares favorably with that observed in recipients of matched unrelated donor allogeneic grafts, but remains a major cause of morbidity and mo...
Unconjugated bilirubin (UCB) is almost insoluble in water at neutral pH, but appears in normal human gallbladder bile at concentrations up to 35 microM. We therefore determined whether conjugated bile salts could increase the dissolved concentration [( Bt]) of UCB over the pH range 3.0-11.0. Using crystalline UCB, [Bt] was higher with less ordered crystals, with increasing pH and bile salt conc...
BACKGROUND Carcinoembryonic antigen-related cell adhesion molecule 1 (biliary glycoprotein; CEACAM1) is expressed in normal bladder urothelium and in angiogenically activated endothelial cells, where it exhibits proangiogenic properties. OBJECTIVE The aim of this study was to evaluate the value of urinary CEACAM1 for detection of urothelial carcinoma of the bladder (UCB). DESIGN, SETTING, A...
OBJECTIVE Cyclosporin A (CsA), effective in prophylaxis and treatment of graft-vs-host disease (GVHD) after human allogeneic transplantation, blunts T-cell responses by inhibiting nuclear factor of activated T cells-1 (NFAT1) activation. This laboratory has shown that NFAT1 protein expression is severely reduced in human UCB (umbilical cord blood) T cells. Since UCB is increasingly used as a he...
