Consider the gene ranking problem of replicated microarray time course experiments where there are multiple biological conditions, and genes of interest are those whose temporal profiles are different across conditions. We derive the multi-sample multivariate empirical Bayes statistic for ranking genes in the order of differential expression, from both longitudinal and cross-sectional replicate...

background: the microarray technology is in needed of cost-effective, low background noise and stable substrates for successful hybridization and analysis. methods: in this research, we developed a three-dimentional stable and mechanically reliable microarray substrates by coating of two polymeric layers on standard microscope glass slides. for fabrication of these substrates, a thin film of ox...

Detecting periodicity signals from time-series microarray data is commonly used to facilitate the understanding of the critical roles and underlying mechanisms of regulatory transcriptomes. However, time-series microarray data are noisy. How the temporal data structure affects the performance of periodicity detection has remained elusive. We present a novel method based on empirical mode decomp...

Background and Objective: In recent years, DNA microarray technology has become a central tool in genomic research. Using this technology, which made it possible to simultaneously analyze expression levels for thousands of genes under different conditions, massive amounts of information will be obtained. While traditional clustering methods, such as hierarchical and K-means clustering have been...

Introduction & Objective: The link between dietary fat and coronary heart disease has attracted much attention since the effect of long?chain fatty acids (LCFA) on gene transcription has been established, which in part, these effects can be explained by the regulation of gene transcription. In this study, the P19CL6 cardiac cell?line was targeted for the investigation of (i) the effects of long...

Background:  Preeclampsia (PE) is a heterogeneous pregnancy disease which the exact pathophysiology of it is unknown. Recently exosomes have been indicated as a causative factor in the pathogenesis of PE. The aim of the study was to investigate in microarray library data to extract the differentially expressed genes (DEGs) in PE and to perform a functional enrichment analysis to predict the rol...

Protein biomarkers in nasal secretions can be used as a measure to differentiate between allergies, airway diseases and infections for non-invasive diagnostics. The point-of-care quantification of biomarker levels using flow-based microarray facilitates precise rapid diagnosis displays the potential targeted effective treatment. For first time, we developed chemiluminescence sandwich immunoassa...

The paper describes comparative evaluation of IAVchip DNA microarray, reverse transcription PCR (RT-PCR), and real-time RT-PCR versus virus isolation in chicken embryos and shows their diagnostic effectiveness in detection and subtyping of influenza A virus. The tests were evaluated with use of 185 specimens from humans, animals, and birds. IAVchip DNA microarray demonstrates higher diagnostic ...
