Effect of spring-back in v-tool bending of high-strength steel sheet metal plates

This paper deals with the effects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the FEM simulations. Also by variation of different mechanical material properties, effects on product geometry are observed. Since the automobile manufacturers mostly use the high strength steel sheet metal plates, there is a need for the successful tool construction and optimization in order to produce quality products

Dijagnostika gravidnosti koza

Dijagnostika gravidnosti bitan je segment veterinarske djelatnosti u upravljanju i kontroli rasplođivanja koza, posebice prilikom držanja u intenzivnom uzgoju. Premda vlasnik životinje može posumnjati na gravidnost, neizbježna je uloga veterinara da kliničkom pretragom i metodama poput ultrazvuka ili laboratorijskih testova utvrdi je li životinja gravidna ili nije i shodno tomu poduzme sve potrebne mjere oko reproduktivnog statusa životinje. Specifičnost spolnog ciklusa koza i sezonska poliestričnost dodatne su okolnosti i stvaraju potrebu za što ranijom dijagnostikom gravidnosti. Zadnjih četrdesetak godina dijagnostičke metode su usavršene tako da je moguće relativno brzo i lako dobiti nalaze dijagnostike, i to ne samo gravidnosti nego i podatke o starosti plodova, njihovoj brojnosti i vitalnosti

A common variant of the MACC1 gene is significantly associated with overall survival in colorectal cancer patients

<p>Abstract</p> <p>Background</p> <p>The newly discovered metastasis-associated in colon cancer-1 (MACC1) gene is a key regulator of the HGF/MET pathway. Deregulation of HGF/MET signaling is reported as a prognostic marker for tumorigenesis, early stage invasion, and metastasis. High expression levels of MACC1 have been associated with colon cancer metastasis and reduced survival. Potential links between the genetic diversity of the MACC1 locus and overall survival are unknown. We therefore investigated the association between MACC1 tagging single nucleotide polymorphisms (SNPs) and overall survival in a large cohort of colorectal cancer patients.</p> <p>Methods</p> <p>The study included 318 subjects with histopathologically proven colorectal cancer at the Academic Teaching Hospital Feldkirch, Austria. Survival data were provided by the federal agency for statistics in Austria. Genomic DNA was isolated from formalin-fixed paraffin-embedded specimens; six tagging SNPs (rs1990172, rs3114446, rs10275612, rs3095007, rs3095009, and rs7780032), capturing most of the common variants of the MACC1 locus, were genotyped by SNaPshot assays.</p> <p>Results</p> <p>Over a mean follow up period of 5.3 (± 1.0) years, 94 deaths were recorded. Carriers of the G-allele of SNP rs1990172 showed a significantly decreased overall survival (additive HR = 1.38 [1.05-1.82]; <it>p </it>= 0.023). Multivariate analysis adjusted for age and UICC tumor stage confirmed this result (HR = 1.49 [1.12-1.98]; <it>p </it>= 0.007). Other investigated genetic variants of the MACC1 gene were not significantly associated with overall survival (<it>p</it>-values > 0.05).</p> <p>Conclusions</p> <p>For the first time, our study investigated the influence of MACC1 tagging polymorphisms on overall survival suggesting SNP rs1990172 as a predictor for reduced overall survival in colorectal cancer patients. Further studies will be required to validate our findings.</p
