A collaborative study was designed to asses two freeze-dried human plasma preparations containing anti-Treponema pallidum antibodies, 05/132 and 05/122, for their suitability as international reference reagents for syphilis serology. Both preparations are intended as replacements of the first international standard (IS) for syphilitic serum antibodies (HS). Samples were tested by eight laborato...

To compare intravenous (iv) ceftriaxone and penicillin G as therapy for neurosyphilis, blood and CSF were collected before and 14-26 weeks after therapy from 30 subjects infected with human immunodeficiency virus (HIV)-1 who had (1) rapid plasma reagin (RPR) test titers >/=1&rcolon;16, (2) reactive serum treponemal tests, and (3) either reactive CSF-Venereal Disease Research Laboratory (VDRL) t...

Venereal diseases are still a common prohlem in today's world. Even though tremendous advances are heing made in medicine and large budgets are heing spent to control sexually transmitted diseases (STD), especially in western countries, these diseases are still yet very common, and today AIDS has been added to the threats posed hy STD to human life. The status of syphilis was evaluated in Iran ...

The purpose of this study was to evaluate the diagnostic performance of LIAISON Treponema Screen (DiaSorin, Saluggia, Italy), a new automated chemiluminescence immunoassay (CLIA), in comparison with that of rapid plasma reagin (RPR) and the following currently used treponemal tests: hemagglutination test (TPHA), immunoenzymatic assay (EIA), and Western blot (WB). First, a retrospective study wa...

RNase P is primarily responsible for the 5΄ maturation of transfer RNAs (tRNAs) in all domains of life. Archaeal RNase P is a ribonucleoprotein made up of one catalytic RNA and five protein cofactors including L7Ae, which is known to bind the kink-turn (K-turn), an RNA structural element that causes axial bending. However, the number and location of K-turns in archaeal RNase P RNAs (RPRs) are u...

This paper uses the kinematic mapping into the image space of spherical displacements to design a cooperating spherical robot system for workpiece orientating. The kinematic chain formed b y the cooperating robots grasping the workpiece forms a multi degree of freedom closed chain which is also known as a robotic mechanism. The spherical robots considered are spherical RPR open chains and they ...

Introduction: The mortality rate in Sanglah Hospital due to major burns is quite high. ratio of red cell distribution width (RDW) and platelet (PLT) (RPR) as a prognostic marker has never been studied Indonesia. Calculations RPR are easy, widely available cost-efficient.Method: This study was retrospective observational case-control, with 60 patients consisting 30 cases controls. Samples were t...

BACKGROUND AND PURPOSE Some studies have reported that the risk factors for neurosyphilis in patients with human immunodeficiency virus (HIV) and syphilis co-infection, include CD4 cell counts ≤350cells/μL and rapid plasma reagin (RPR) titer ≥1:32. However, neurosyphils can develop even in patients with CD4 cell counts >350cells/μL or RPR titer <1:32. In this study, we evaluated the outcome of ...

Ten sporadic cases of venereal spirochaetosis, caused by Treponema paraluis-cuniculi, were seen in New Zealand white rabbits in two years. An equal number of males and females were affected. Females tended to have milder clinical signs than males. Lesions were usually found on the prepuce in males and the vulva in females, although the anus and skin of the perineum were also affected. Facial le...
