Research ArticleOpen accessAll words, across the recordA Novel Distinguishability Based Weighted Feature Selection Algorithms for Improved Classification of Gene Microarray DatasetJ. Jeyachidra, M. PunithavalliData mining played vital role in comprehending, analyzing, understanding and interpreting microarray technology expression data. That includes search for genes that had similar or correlated patterns of expression. For that, the feature selection was one of the frequently used important techniques for data preprocessing. Many feature selection algorithms had been developed. Yet the persisting problem was in selecting optimal subset … …Journal of Computer Science, Vol. 11, Issue 2 · 2 Feb 2015 · 6,376 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHypoxia-Inducible Factor 1α Expression in Chorionic Tissue and Decidua of Women with Spontaneous Abortion at the First Trimester of PregnancyE. V. Mashkina, K. A. Kovalenko, E. V. ButenkoOxygen-regulated genes expression has important role in pre-implantation embryonic metabolism regulation. Hypoxia Inducible Factor (HIF) regulated by hypoxia oxygen tension is crucial for placenta development. But the data about its role in spontaneous abortion is very poor. Thus, we aimed to determine an expression level of HIF-1α in chorionic tissue and decidua at pregnancy. Samples of chorionic tissue and decidua … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 18 Nov 2014 · 6,862 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDifferential Gene Expression in Zebrafish (Danio rerio) Following Exposure to Gaseous Diffusion Plant Effluent and Effluent Receiving Stream WaterBen F. Brammell, Andrew J. WiggintonProblem statement: The expression of six genes known to serve as bioindicators of environmental stress were examined using real-time quantitative PCR in liver tissue extracted from zebrafish (Danio rerio, Hamilton) exposed to effluent and effluent containing stream water associated with the Paducah Gaseous Diffusion Plant (PGDP). Approach: The PGDP, the only active uranium enrichment facility in the US, is located … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,770 accessesView PDF Cite
