Autoantibody profile differentiates BP phenotypes
No full textBullous pemphigoid (BP) is a major autoimmune blistering skin disorder, in which a majority of the autoantibodies (autoAbs) target the juxtamembranous extracellular noncollagenous 16A domain (NC16A) domain of hemidesmosomal collagen XVII. BP-autoAbs may target regions of collagen XVII other than the NC16A domain; however, correlations between epitopes of BP-autoAbs and clinical features have not been fully elucidated. To address correlations between the clinical features and specific epitopes of BP-autoAbs, we evaluated the epitope profiles of BP-autoAbs in 121 patients. A total of 87 patients showed a typical inflammatory phenotype with erythema and autoAbs targeting the anti-NC16A domain, whereas 14 patients showed a distinct noninflammatory phenotype, in which autoAbs specifically targeted the midportion of collagen XVII, but not NC16A. Interestingly, this group clinically showed significantly reduced erythema associated with scant lesional infiltration of eosinophils. Surprisingly, 7 of the 14 cases (50.0%) received dipeptidyl peptidase-IV inhibitors for the treatment of diabetes. Dipeptidyl peptidase-IV inhibitors were used in 3 of 76 (3.9%) typical cases of BP with autoAbs targeting NC16A; thus, dipeptidyl peptidase-IV inhibitors are thought to be involved in the development of atypical noninflammatory BP. This study shows that the autoAb profile differentiates between inflammatory and noninflammatory BP, and that noninflammatory BP may be associated with dipeptidyl peptidase-IV inhibitors
Link prediction in author collaboration network based on BP neural network
No full textRecently, more and more authors have been encouraged for collaboration because it often produces good results. However, the author collaboration network contains experts in various research directions within various fields, and it is difficult for individual authors to decide which authors are best suited to their expertise. This paper uses the relationships among authors to predict new relationships that may arise, recommending each author with the collaborators they may be interested in. The data source comes from 4-year data in DBLP from 2001 to 2004. After data cleaning, the training set and test set are constructed and then used BP neural network to build model. At the same time, this article compares the performance with Logistic Regression, SVM and Random Forest. The experiment shows that the BP neural network can get better result, and it is feasible to predict links in the author collaboration network

A joint genomewide linkage analysis of symptoms of alcohol dependence and conduct disorder.

No full textFix a prime number p and an integer n≥ 0. We prove that if a p-complete spectrum X satisfying a mild finiteness condition has the same mod p cohomology as BP⟨ n⟩ as a module over the Steenrod algebra, then X is weak homotopy equivalent to the p-completion of BP⟨ n⟩.The first author was supported by an ARC Discovery grant.

IntCal09 and Marine09 radiocarbon age calibration curves, 0–50,000 years cal BP

This article is posted here by permission of Dept. of Geosciences, University of Arizona for personal use, not for redistribution. The definitive version was published in Radiocarbon 51 (2009): 1111-1150.The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is
here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP, utilizing newly available data sets
that meet the IntCal Working Group criteria for pristine corals and other carbonates and for quantification of uncertainty in
both the 14C and calendar timescales as established in 2002. No change was made to the curves from 0–12 cal kBP. The curves
were constructed using a Markov chain Monte Carlo (MCMC) implementation of the random walk model used for IntCal04
and Marine04. The new curves were ratified at the 20th International Radiocarbon Conference in June 2009 and are available
in the Supplemental Material at www.radiocarbon.org.We would like to acknowledge support for this project from the UK Natural Environment Research

Inhibitors of CRD-BP-KRAS RNA interaction
No full textThe KRAS mRNA is one of few oncogenic mRNAs that can be recognized and bound by the RNA-binding protein called Coding Region Determinant-Binding Protein (CRD-BP). Binding of CRD-BP to oncogenic mRNAs can ultimately increase the possibility of tumor occurrence. Given that CRD-BP is only expressed in adult cancers but not in normal tissues, targeting the CRD-BP-mRNA interaction is a good anti-cancer strategy. To study CRD-BP-KRAS mRNA interaction and to search for inhibitors of such interaction, a safe, sensitive and high throughput-based fluorescence polarization (FP) method was developed. By using a 44 nts fluorescein-labeled KRAS RNA, a library of 217 small molecules was screenedfor their ability to inhibit CRD-BP-KRAS RNA interaction. Finally, candidate small molecule inhibitors as well as effective antisense oligonucleotides (AONs) against KRAS RNA were assessed for their ability to suppress KRAS gene expression in cancer cells.KRASmRNACRD-BPtumorcance
