Syphilis screening by the nontreponemal rapid plasma reagin (RPR) test is not usually followed up by specific treponemal tests in most of the resource poor healthcare settings of Nepal. We analyzed serum specimens of 504 suspected syphilis cases at the immunology department of the national reference laboratory in Nepal during 2007-2009 using RPR test and Treponema pallidum hemagglutination assa...

Activation of human ether-a-go-go-related gene 1 (hERG1) K(+) channels mediates repolarization of action potentials in cardiomyocytes. RPR-260243 [(3R,4R)-4-[3-(6-methoxy-quinolin-4-yl)-3-oxo-propyl]-1-[3-(2,3,5-trifluorophenyl)-prop-2-ynyl]-piperidine-3-carboxylic acid] (RPR) slows deactivation and attenuates inactivation of hERG1 channels. A detailed understanding of the molecular mechanism o...

Radix Paeoniae Rubra (RPR) is the dried root of Paeonia lactiflora Pallas and Paeonia veitchii Lynch, and is a herbal medicine that is widely used in traditional Chinese medicine for the treatment of blood-heat and blood-stasis syndrome, similarly to Cortex Moutan. The present study identified the same three components in RPR and Cortex Moutan extracts. In addition, it has been reported that RP...

Developmentally regulated apoptosis in Drosophila requires the activity of the reaper (rpr), grim and head involution defective (hid) genes. The expression of these genes is differentially regulated, suggesting that there are distinct requirements for their proapoptotic activity in response to diverse developmental and environmental inputs. To examine this hypothesis, a mutation that removes th...

Methods Open-label, no controlled study of a series of HIV-patients diagnosed with syphilis during 2004 2011. Patients were categorized by rapid plasma reagin titer (RPR) into success (4-fold decrease in RPR by 12 or 24 months after treatment of early or late syphilis), serofast (success with persistently stable reactive RPR), and failure/re-infection (failure to decrease 4-fold in RPR by 12 or...

This study evaluates the American Dade (Biokit Laboratories) rapid plasma reagin (Dade RPR) card test, currently used in Spain for the diagnosis of syphilis, which has been recently released to the U.S. market. Used as a basis for comparison with the Dade card test were the 18-mm standard rapid plasma reagin (standard RPR) card test and the Venereal Disease Research Laboratory (VDRL) slide test...

Background : The purpose of this study was to evaluate validity of quantitative RPR LTIA, HiSens Auto RPR LTIA (HBi Corp., South Korea) and to decide an adequate cutoff value for syphilis screening. Materials and Methods : A total of 549 serums or plasma specimens from patients were tested with RPR LTIA and RPR card tests. Degree of agreement between the two methods was analyzed, and validity o...

OBJECTIVE This report presents national reference data on resting pulse rate (RPR), for all ages of the U.S. population, from 1999-2008. METHODS During 1999-2008, 49,114 persons were examined. From this, a normative sample comprising 35,302 persons was identified as those who did not have a current medical condition or use a medication that would affect the RPR. RPR was obtained after the par...

A novel framework for pattern recognition, namely Relative Pattern Recognition (RPR), is presented in this paper. RPR is based on a relative feature representation/extraction method. While traditional feature extraction determines features to discriminate all the classes in a given domain, RPR extracts relative features to separate only two classes at a time. The feature determination process b...
