The effects of L1-Fc and CHL1-Fc fusion proteins on neuronal survival were investigated. Cerebellar granule neurons of mouse and hippocampal neurons of rat embryo undergo apoptosis when cultured in serum-free medium. Treatment with chimeric proteins containing the extracellular domains of the neural adhesion molecules L1 or CHL1 fused to the Fc region of(More)
A system of nested dichotomies is a hierarchical decomposition of a multi-class problem with c classes into c − 1 two-class problems and can be represented as a tree structure. Ensembles of randomly-generated nested dichotomies have proven to be an effective approach to multi-class learning problems [1]. However, sampling trees by giving each tree equal(More)
To investigate the role of the corticotropin releasing hormone receptor 1 (CRHR1) in patterns of human alcohol drinking and its potential contribution to alcohol dependence, we analysed two independent samples: a sample of adolescents, which consisted of individuals from the 'Mannheim Study of Risk Children' (MARC), who had little previous exposure to(More)
Motivated by various challenging real-world applications, such as drug activity prediction and image retrieval, multi-instance (MI) learning has attracted considerable interest in recent years. Compared with standard supervised learning, the MI learning task is more difficult as the label information of each training example is incomplete. Many MI(More)
Ediacara fossils [575 to 542 million years ago (Ma)] represent Earth's oldest known complex macroscopic life forms, but their morphological history is poorly understood. A comprehensive quantitative analysis of these fossils indicates that the oldest Ediacara assemblage-the Avalon assemblage (575 to 565 Ma)-already encompassed the full range of Ediacara(More)
Cisplatin resistance presents a major challenge in the successful treatment of breast cancer, and its mechanism has not been documented well. In this study, to determine the relationship between chemotherapy resistance and microRNA (miRNA) expression during the development of cisplatin resistance in breast cancer, we used microRNA microarrays analysis(More)
In a (k, n) visual secret sharing (VSS) scheme, the alignment of the transparencies is important to the visual quality of the reconstructed secret image. Each pixel of the original secret image is expanded to m subpixels in a share image. If a share image is printed on a paper with the same size as the original secret image, the alignment or the(More)
PURPOSE To estimate the therapeutic potential of PD-L1 inhibition in breast cancer, we evaluated the prevalence and significance of PD-L1 protein expression with a validated antibody and CD274 gene alternation in a large cohort of triple negative breast cancer (TNBC) and correlated with clinicopathological data and patients overall survival. METHODS(More)
The peroxiredoxin (Prx) protein is expressed widely in animal tissues and serves an antioxidant function associated with removal of cellular peroxides. We have cloned two Prx genes and observed differential expression of Prx-I and Prx-II (formerly NKEF-A and NKEF-B) in purified rat brain cell cultures (Sarafian et al. [1998] Mol. Chem. Neuropathol.(More)
As of May 19, 2009, a total of 5,469 confirmed or probable cases of human infection with a novel influenza A (H1N1) virus had been documented in 47 states and the District of Columbia. In addition, the virus had spread to 41 countries, with a total of 4,774 cases reported in countries outside the United States. Because producing a novel influenza A (H1N1)(More)
