The US Department of Energy is funding the world’s first cold dielectric superconducting power cable demonstration project at transmission level voltage, to be installed at the Long Island Power Authority (LIPA) grid in 2007. The cable is designed to carry 574 MVA at a voltage of 138 kV. It will remain installed as a permanent part of the LIPA grid. The project team is comprised of American Sup...

The performance to detect drug resistance mutations in the reverse transcriptase gene of HIV-1 was compared for direct solid phase sequencing, selective polymerase chain reaction (PCR) using the amplification refractory mutation system (ARMS) and the new line probe assay (LIPA) HIV-1 RT. The three tests were undertaken on 50 plasma samples from 25 treatment-experienced patients under combinatio...

Intracellular bacterial pathogens manipulate host cell functions by producing enzymes that stimulate or antagonize signal transduction. The Listeria monocytogenes genome contains a gene, lmo1800, encoding a protein with a conserved motif of conventional tyrosine phosphatases. Here, we report that the lmo1800-encoded protein LipA is secreted by Listeria and displays tyrosine as well as lipid pho...

A total of 54 rapidly growing mycobacteria (RGM) isolated from patients attended in the two hospitals of Cádiz Bay (Spain) were selected during a seven-year-period (2000-2006) in order to evaluate the INNO-LiPA Mycobacteria v2 assay for mycobacterial identification, based on the reverse hybridization principle. The strains were cultured in Löwenstein-Jensen and Middlebrook 7H9 media and identif...

Thermosyntropha lipolytica DSM 11003, an anaerobic thermophilic lipolytic bacterium, produces the two alkalithermophilic lipases, LipA and LipB. Among all tested detergents, the two lipases were mostly affected by SDS when used at concentrations below its critical micelle concentration (CMC). In the absence of SDS, the v(max) of both LipA and LipB were 12.6 U.mg(-1) and 13.3 U.mg(-1) and K(0.5)...

OBJECTIVE To evaluate the use of hepatitis C virus (HCV) NS3 sequencing as alternative to the comercially available Versant HCV 2.0 reverse hybridization line-probe assay (LiPA 2.0) to determine HCV genotype 1 (HCV-1) subtypes. PATIENTS AND METHODS A cohort of 104 patients infected by HCV-1 according to LiPA 2.0 was analyzed in a cross-sectional study conducted in patients seen from January 2...

Evaluation of drug resistance by human immunodeficiency virus (HIV) genotyping has proven to be useful for the selection of drug combinations with maximum antiretroviral activity. We compared three genotyping methods for identification of mutations known to confer drug resistance in the reverse transcriptase (RT) and protease genes of HIV type 1 (HIV-1). The HIV-GenotypR method (GenotypR; Speci...

The associations between time spent in sleep, sedentary behaviors (SB) and physical activity with health are usually studied without taking into account that time is finite during the day, so time spent in each of these behaviors are codependent. Therefore, little is known about the combined effect of time spent in sleep, SB and physical activity, that together constitute a composite whole, on ...

Mycobacterium tuberculosis resistance to rifampin results from nucleotide changes in the gene encoding the beta-subunit of the RNA polymerase (rpoB). We developed a reverse hybridization-based line probe assay (LiPA; the INNO-LiPA Rif. TB) carrying one oligonucleotide probe for the detection of M. tuberculosis complex strains and nine probes designed to detect nucleotide changes in the relevant...

BACKGROUND T2 mapping is an MRI method particularly reflective of the collagen arrangement in the cartilage, and diffusion tensor (DT) imaging captures the diffusion of water molecules. Laser-induced photoacoustic measurement (LIPA) makes it possible to assess not only the thickness of the cartilage layer but also its viscoelastic properties. By assessing cartilage damage assessment using LIPA ...
