PURPOSE Esophageal squamous cell carcinoma (ESCC) is an aggressive tumor with poor prognosis. Understanding molecular changes in ESCC will enable identification of molecular subtypes and provide potential targets for early detection and therapy. EXPERIMENTAL DESIGN We followed up a previous array study with additional discovery and confirmatory studies in new ESCC cases by using alternative m...

PURPOSE To determine the effects of proinflammatory cytokines on differential gene expression profiles in the human corneal endothelium (HCE), by using a cDNA expression array. METHODS A human cDNA expression array technology was used to study the simultaneous expression of HCE incubated with interleukin (IL)-1alpha and tumor necrosis factor-(TNF)-alpha. Gene-specific semiquantitative reverse...

background: disorders of sex development (dsds) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,xy ...

uniform linear array (ula)-based tapped-delay line (tdl) structure has good performance metrics when the signal sources are located at the middle angles. it offers poor performance when the signal sources are close to the array endfire. in this paper, a new approach is proposed which offers higher performance and desired beamforming on tdl structure when the wideband uncorrelated radio sources ...

A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...

PCR single-stranded conformational polymorphism (SSCP) analysis is a simple and rapid electrophoretic technique for the sensitive detection of sequence variants of PCR products. Here we describe a cross-platform program package, quantitative interpretation of SSCP in capillary array (QUISCA), which allows semi-automated quantitative detection of sequence variants separated by multicolor fluores...

The pathogenesis of Lassa fever is poorly understood. As the liver is a major target organ of Lassa virus, gene expression in Lassa virus-infected HuH-7 cells, a differentiated human hepatoma cell line, was studied. Cellular mRNA levels were measured at the late phase of acute infection, when virtually all cells expressed large amounts of nucleoprotein, and virus RNA concentration had reached>1...

A gene-specific microsphere suspension array coupled with 15-plex polymerase chain reaction (PCR) was developed to screen bacterial samples rapidly for 10 strains of bacteria: Shigella spp. (S. flexneri, S. dysenteriae, and S. sonnei), Staphylococcus aureus, Vibrio cholerae (serology O1 and O139), Legionella pneumophila, and Clostridium botulinum (types A, B, and E). Fifteen sets of highly vali...

We have developed a highly sensitive method for DNA analysis on 3D gel element microarrays, a technique we call multiplex microarray-enhanced PCR (MME-PCR). Two amplification strategies are carried out simultaneously in the reaction chamber: on or within gel elements, and in bulk solution over the gel element array. MME-PCR is initiated by multiple complex primers containing gene-specific, forw...
