Do Media Data Help to Predict German Industrial Production?

In an uncertain world, decisions by market participants are based on expectations. Therefore, sentiment indicators reflecting expectations have a proven track record at predicting economic variables. However, survey respondents largely perceive the world through media reports. Here, we want to make use of that. We employ a rich dataset provided by Media Tenor International, based on sentiment analysis of opinion‐leading media in Germany from 2001 to 2014, transformed into several monthly indices. German industrial production is predicted in a real‐time out‐of‐sample forecasting experiment and media indices are compared to a huge set of alternative indicators. Media data turn out to be valuable for 10‐ to 12‐month horizon forecasts, which is in line with the lag between monetary policy announcements and their effect on industrial production. This holds in the period during and after the Great Recession when many models fail. Copyright © 2016 John Wiley & Sons, Ltd.     

Sequence variants in IL10, ARPC2 and multiple other loci contribute to ulcerative colitis susceptibility

Inflammatory bowel disease (IBD) typically manifests as either ulcerative colitis (UC) or Crohn's disease (CD). Systematic identification of susceptibility genes for IBD has thus far focused mainly on CD, and little is known about the genetic architecture of UC. Here we report a genome-wide association study with 440,794 SNPs genotyped in 1,167 individuals with UC and 777 healthy controls. Twenty of the most significantly associated SNPs were tested for replication in three independent European case-control panels comprising a total of 1,855 individuals with UC and 3,091 controls. Among the four consistently replicated markers, SNP rs3024505 immediately flanking the IL10 (interleukin 10) gene on chromosome 1q32.1 showed the most significant association in the combined verification samples (P = 1.35 x 10(-12); OR = 1.46 (1.31-1.62)). The other markers were located in ARPC2 and in the HLA-BTNL2 region. Association between rs3024505 and CD (1,848 cases, 1,804 controls) was weak (P = 0.013; OR = 1.17 (1.01-1.34)). IL10 is an immunosuppressive cytokine that has long been proposed to influence IBD pathophysiology. Our findings strongly suggest that defective IL10 function is central to the pathogenesis of the UC subtype of IBD.     

Replication of signals from recent studies of Crohn's disease identifies previously unknown disease loci for ulcerative colitis

Following up on recent genome-wide association studies (GWAS) of Crohn's disease, we investigated 50 previously reported susceptibility loci in a German sample of individuals with Crohn's disease (n = 1,850) or ulcerative colitis (n = 1,103) and healthy controls (n = 1,817). Among these loci, we identified variants in 3p21.31, NKX2-3 and CCNY as susceptibility factors for both diseases, whereas variants in PTPN2, HERC2 and STAT3 were associated only with ulcerative colitis in our sample collection.     

A common variant of HMGA2 is associated with adult and childhood height in the general population

Human height is a classic, highly heritable quantitative trait. To begin to identify genetic variants influencing height, we examined genome-wide association data from 4,921 individuals. Common variants in the HMGA2 oncogene, exemplified by rs1042725, were associated with height (P = 4 x 10(-8)). HMGA2 is also a strong biological candidate for height, as rare, severe mutations in this gene alter body size in mice and humans, so we tested rs1042725 in additional samples. We confirmed the association in 19,064 adults from four further studies (P = 3 x 10(-11), overall P = 4 x 10(-16), including the genome-wide association data). We also observed the association in children (P = 1 x 10(-6), N = 6,827) and a tall/short case-control study (P = 4 x 10(-6), N = 3,207). We estimate that rs1042725 explains approximately 0.3% of population variation in height (approximately 0.4 cm increased adult height per C allele). There are few examples of common genetic variants reproducibly associated with human quantitativetraits; these results represent, to our knowledge, the first consistently replicated association with adult and childhood height.     

Targeting the DNA repair defect in BRCA mutant cells as a therapeutic strategy

BRCA1 and BRCA2 are important for DNA double-strand break repair by homologous recombination, and mutations in these genes predispose to breast and other cancers. Poly(ADP-ribose) polymerase (PARP) is an enzyme involved in base excision repair, a key pathway in the repair of DNA single-strand breaks. We show here that BRCA1 or BRCA2 dysfunction unexpectedly and profoundly sensitizes cells to the inhibition of PARP enzymatic activity, resulting in chromosomal instability, cell cycle arrest and subsequent apoptosis. This seems to be because the inhibition of PARP leads to the persistence of DNA lesions normally repaired by homologous recombination. These results illustrate how different pathways cooperate to repair damage, and suggest that the targeted inhibition of particular DNA repair pathways may allow the design of specific and less toxic therapies for cancer.     

Structure of the SRP19 RNA complex and implications for signal recognition particle assembly

The signal recognition particle (SRP) is a phylogenetically conserved ribonucleoprotein. It associates with ribosomes to mediate co-translational targeting of membrane and secretory proteins to biological membranes. In mammalian cells, the SRP consists of a 7S RNA and six protein components. The S domain of SRP comprises the 7S.S part of RNA bound to SRP19, SRP54 and the SRP68/72 heterodimer; SRP54 has the main role in recognizing signal sequences of nascent polypeptide chains and docking SRP to its receptor. During assembly of the SRP, binding of SRP19 precedes and promotes the association of SRP54 (refs 4, 5). Here we report the crystal structure at 2.3 A resolution of the complex formed between 7S.S RNA and SRP19 in the archaeon Methanococcus jannaschii. SRP19 bridges the tips of helices 6 and 8 of 7S.S RNA by forming an extensive network of direct protein RNA interactions. Helices 6 and 8 pack side by side; tertiary RNA interactions, which also involve the strictly conserved tetraloop bases, stabilize helix 8 in a conformation competent for SRP54 binding. The structure explains the role of SRP19 and provides a molecular framework for SRP54 binding and SRP assembly in Eukarya and Archaea.     

可视化供应链结构和处理过程增进对mySAP ERP中信息技术类操作的理解

The following conceptual paper mainly addresses the understanding problem that comes up with teaching business economics and applying this to complex IT-infrastructures and integrated processes within an Enterprise Resource Planning System.Under laboratory conditions,we assume to resolve this lack of understanding during transactional exercises and to confirm pupil's or student's business know-how,while well-evaluated case studies are demonstrated and executed by themselves.To visualize supply chain structures and processes,the authors are presenting a framework for physical LEGO constructions and digital modelling logistic scenarios.
