The CAPTIA Syphilis-G enzyme immunoassay for the detection of antibodies to Treponema pallidum was evaluated as a screening test for syphilis in comparison with the standard rapid plasma reagin (RPR) test. One thousand samples were tested, and the standard fluorescent treponemal antibody absorption test and the standard microhemmaglutination test were used to confirm the presence of treponemal ...

Acute and sub-acute toxic effects of a novel phosphorothionate coded as RPR-II on testis of albino rats were studied. In acute study rats received a single dose of 12.3 mg/kg of RPR-II and sacrificed after 24 hr. For sub-acute study 0.58 mg/kg/day was administered orally to rats for 10 and 21 days. Acute exposure of rats to RPR-II brought no change either in the gonadosomatic index (GSI) or in ...

A scheme often used for error tolerance of arithmetic circuits is the so-called Reduced Precision Redundancy (RPR). Rather than replicating multiple times entire module, RPR uses reduced precision (inexact) copies to significantly reduce redundancy overhead, while still being able correct largest errors. This paper focuses on low-power operation RPR; a new proposed. At circuit level, power gati...

OBJECTIVES To assess the impact of a syphilis control programme of pregnant women on pregnancy outcome in Kenya. METHOD Women who came to deliver to Pumwani Maternity Hospital (PMH) between April 1997 and March 1998 were tested for syphilis. Reactive rapid plasma reagin (RPR) tests were titrated and confirmed with treponema haemagglutination test (TPHA). Equal numbers of RPR and TPHA negative...

The resilient packet ring (RPR), defined under IEEE 802.17, has been proposed as a high-speed backbone technology for metropolitan area networks. RPR is introduced to mitigate the underutilisation and unfairness problems associated with the current technologies SONET and Ethernet, respectively. The key performance objectives of RPR are to achieve high bandwidth utilisation, optimum spatial reus...

We recently demonstrated that squalene synthase (SQS) inhibitors reduce plasma triglyceride through an LDL receptor-independent mechanism in Watanabe heritable hyperlipidemic rabbits (Hiyoshi et al. 2001. Eur. J. Pharmacol. 431: 345-352). The present study deals with the mechanism of the inhibition of triglyceride biosynthesis by the SQS inhibitors ER-27856 and RPR-107393 in rat primary culture...

OBJECTIVES An increasing number of institutions are transitioning from the traditional syphilis testing algorithm (initial screening with nontreponemal tests) to the 'reverse' algorithm (initial screening with treponemal tests such as syphilis IgG). The aim of this study was to evaluate the switch in syphilis algorithm at an academic medical center with a population with low syphilis prevalence...

OBJECTIVE To evaluate changes in residual platelet reactivity (RPR) over time, and bleeding and ischaemic events rate using 5 vs 10 mg maintenance dose (MD) regimens of prasugrel 1 month after acute coronary syndrome (ACS). BACKGROUND The optimal level of RPR with prasugrel may change over time after an ACS. METHODS After 60 mg loading dose of prasugrel (T0) followed by 10 mg/day for 1 mont...

Abstract Background Syphilis infection caused by the bacterium Treponema pallidum is a sexually transmitted leading to serious health complications if undiagnosed or untreated. Serologic diagnostic methods include combined approach for detection of antibodies non-treponemal (RPR) and treponemal antigens using traditional reverse algorithm. The BioPlex2200 Total/RPR assay (BioRad Laboratories) a...

A genomic interval at 75C1,2 is required for programmed cell death in Drosophila. We identified a new activator of apoptosis, grim, which maps between two previously identified cell death genes in this region reaper (rpr) and head involution defective (hid). Expression of grim RNA coincided with the onset of programmed cell death at all stages of embryonic development, whereas ectopic induction...
