DNA chips perform the rapid, parallel detection of a target set of gene transcripts through specific hybridization of targets to DNA probes integrated on the chip surface [1]. A DNA chip can thus be considered as a special purpose DNA computer for parallel homology search. Conventional DNA chips rely solely on hybridization for transcript detection. As a result, the recognition process for geno...

INTRODUCTION Transcription factors and other chromatin-associated proteins are essential phenotype-influencing mechanisms. Determining how proteins interact with DNA to regulate gene expression is essential for fully understanding many biological processes and disease states. This epigenetic information is complimentary to genotype and expression analysis. Traditional methods have successfully ...

This paper describes a vision chip architecture for high-speed vision systems that we propose. The chip has general-purpose processing elements (PEs) in a massively parallel architecture, with each PE directly connected to photo-detectors. Control programs allow various visual processing applications and algorithms to be implemented. A sampling rate of 1ms is enough to realize high-speed visual...

An isothermal signal amplification technique for specific DNA sequences, known as cycling probe technology (CPT), was performed within a microfluidic chip. The presence of DNA from methicillin-resistant Staphylococcus aureus was determined by signal amplification of a specific DNA sequence. The microfluidic device consisted of four channels intersecting to mix the sample and reagents within 55 ...

in this study, effect of two genotype imputation strategies, relatedness between reference panel and test populations and minor allele frequency on imputation error rate were examined with using a stochastic simulated population. reference panel and test populations were composed of 1,000 and 500 individuals, respectively. individuals in the reference panel were genotyped with using a high and ...

Examples that show the transfer of our basic knowledge of brain function into practical electronic models are rare. Here we present a user-friendly silicon model of the early visual system that contributes to animal welfare. The silicon chip emulates the neurons in the visual system by using analog Very Large Scale Integration (aVLSI) circuits. It substitutes for a live animal in experiment des...

Many biologically significant processes, such as cell differentiation and cell cycle progression, gene transcription and DNA replication, chromosome stability and epigenetic silencing etc. depend on the crucial interactions between cellular proteins and DNA. Chromatin immunoprecipitation (ChIP) is an important experimental technique for studying interactions between specific proteins and DNA in...

Chromatin immunoprecipitation combined with DNA microarrays (ChIP-chip) is a powerful technique to detect in vivo protein-DNA interactions. Due to low yields, ChIP assays of transcription factors generally require amplification of immunoprecipitated genomic DNA. Here, we present an adapted linear amplification method that involves two rounds of T7 RNA polymerase amplification (double-T7). Using...

Chromatin immunoprecipitation (ChIP) is an invaluable method for studying interactions between specific proteins or modified forms of proteins and a genomic DNA region. ChIP can be used to determine whether a transcription factor interacts with a candidate target gene and is used with equal frequency to monitor the presence of histones with post-translational modifications at specific genomic l...

AIM To develop a diagnostic DNA chip to detect mutations in the betaigh3 gene causing the most common corneal dystrophies (CDs). METHODS Samples from 98 people, including patients with betaigh3-associated CDs (beta-aCDs), were examined. Specific primer and probe sets were designed to examine exons 4 and 12 of the betaigh3 gene, in order to identify mutant and wild-type alleles. Mutations were...
