OBJECTIVES A study found screening (with rapid plasma reagin (RPR)) pregnant women for maternal syphilis was cost-effective in Mwanza, Tanzania. Recently, four rapid point-of-care (POC) syphilis tests were evaluated in Mwanza, and found to have reasonable sensitivity/specificity. This analysis estimates the relative cost-effectiveness of using these POC tests in the Mwanza syphilis screening in...

In area efficient low error compensation multiplier design is using fixed width RPR (Reduced Precision Redundancy). We propose a new method called fixed width RPR for DSP applications. This fixed width multiplier is placed in ANT architecture to meet high speed, low power consumption and area efficiency. The fixed RPR is designed with compensation circuit for minimizing the occurrence of error....

Resilient Packet Ring (RPR) is a dual-ring network, also known as the IEEE 802.17 Standard. As with other IEEE 802 networks, multiple RPR networks can be bridged together to form a bridged network when necessary. However, further research is necessary on additional issues that arise from bridging RPR networks. In this paper, we place emphasize on two of these issues; that is, fairness for inter...

Avoiding singularities in the workspace of a parallel robot is an important issue. The case of 3-RPR planar robots is an important subject of theoretical studies. We study the singularities of planar 3-RPR robots by using a new parameterization of the singular locus in a modified workspace. This approach enables us to give a simple alternative proof of a result recently proved by M. Husty: the ...

Studies have addressed cost-effectiveness of syphilis testing of pregnant women in high-prevalence settings. This study compares costs of rapid syphilis testing (RST) with laboratory-based rapid plasma reagin (RPR) tests in low-prevalence settings in Peru. The RST was introduced in a tertiary-level maternity hospital and in the Ventanilla Network of primary health centers, where syphilis preval...

BACKGROUND Although a higher heart rate is known to be a risk factor for cardiovascular disease (CVD) events, there have been no reports concerning bradycardia. Whether lower and higher resting pulse rates (RPRs) are associated with cardiovascular risk was investigated in subjects from a community-based, prospective cohort study. METHODS After subjects with atrial fibrillation, subjects with ...

The natural trans-acting ribozyme RNase P RNA (RPR) is composed of two domains in which the catalytic (C-) domain mediates cleavage of various substrates. The C-domain alone, after removal of the second specificity (S-) domain, catalyzes this reaction as well, albeit with reduced efficiency. Here we provide experimental evidence indicating that efficient cleavage mediated by the Escherichia col...

BACKGROUND Our objective was to determine the impact of combination antiretroviral therapy (cART) and the degree of immunosuppression on biologic false-positive (BFP) rapid plasma reagin (RPR) tests among persons infected with human immunodeficiency virus (HIV). METHODS This was a nested retrospective study of HIV-infected patients enrolled in the Johns Hopkins HIV Clinical Cohort. BFP RPR wa...

Stalk strength is an important trait in maize (Zea mays L.). Strong stalks reduce lodging and maximize harvestable yield. Studies show rind penetrometer resistance (RPR), or the force required to pierce a stalk rind with a spike, is a valid approximation of strength. We measured RPR across 4,692 recombinant inbreds (RILs) comprising the maize nested association mapping (NAM) panel derived from ...

OBJECTIVE To compare peri-operative complications, pain, and the immediate functional results of the sub-urethral sling procedure for urinary stress incontinence by the retropublic and transobturator routes, using a non-elastic polypropylene sub-urethral sling. PATIENTS AND METHODS This prospective, multicentre study involved 88 women undergoing the sub-urethral sling procedure for stress uri...
