BACKGROUND AND AIM OF THE STUDY Between January 1, 1997 and December 31, 2001, a total of 342 patients underwent aortic valve replacement (AVR) or mitral valve replacement (MVR) with the ATS Medical prosthesis. The initial three-year phase of this study took place under a United States Food and Drug Administration-approved investigational device exemption study. The study aim was to determine t...

In vitro immune effects of Pt compounds of occupational and/or environmental importance, or those used in cancer treatment were studied. Spontaneous and PHA-stimulated proliferation of peripheral blood mononuclear cells (PBMC) and in vitro release of TNF-alpha, IFN-gamma, and IL-5 were assessed in presence of high and very low concentrations of Pt salts: 10(-4) and 10(-7) M (NH4)2[PtCl6], (NH4)...

To assess antibody and cellular immune responses, 156 healthy children were immunized at approximately 18 months of age with acellular diphtheria-tetanus-pertussis vaccine. Changes in antibody responses to filamentous hemagglutinin (FHA) and to pertussis toxin (PT) were similar in pattern, and antibody titers reached values equal to those from patients with convalescent-stage pertussis. The FHA...

BACKGROUND Prolonged isolated thrombocytopenia (PT) is a frequent complication in patients who undergo allogeneic hematopoietic stem cell transplantation (allo-HSCT), and it is associated with an adverse prognosis. In this study, we hypothesized that desialylation on platelet surfaces was associated with PT after allo-HSCT. The mechanisms participating in this process may include NEU1 transloca...

INTRODUCTION Regular participation in external quality assessment (EQA) is critical for maintaining laboratory performance and is required for laboratory accreditation. Proficiency testing (PT) is effective for providing EQA, but available schemes rarely address the range of tests performed by peripheral laboratories in resource-limited settings. The East African Regional External Quality Asses...

PURPOSE We sought to document the difference in the vitreoretinal configuration of Stage 4 retinopathy of prematurity (ROP) in photocoagulated and treatment naive eyes undergoing vitrectomy and to correlate it with surgical complexity. METHODS Consecutive eyes posted for vitrectomy with Stage 4 ROP were documented preoperatively using a RetCam for the presence of peripheral traction (PT), pre...

This letter reports measurements which characterize the underlying event associated with hard scatterings at mid-pseudorapidity (|η|<0.8) in pp, p–Pb and Pb–Pb collisions centre-of-mass energy per nucleon pair, sNN=5.02 TeV. The are performed ALICE LHC. Different multiplicity classes defined based on activity measured forward rapidities. identified by leading particle as charged largest transve...

Very recently the STAR collaboration reported measurement of the probability, P , for emission of at least one hadron with pt ≥ 0.5GeV/c, |η| ≤ 0.75 in association with production of a very forward high pt neutral pion in pp and dAu collisions. We calculate the A-dependence of the hard contributions to P assuming conventional relationship between the number of wounded nucleons and the hadron mu...

      Paclitaxel is a highly effective anticancer agent. It is active against a broad range of cancers that are generally considered refracto...

The goal of the present experiments was to examine the accessibility of concepts embedded within text. J. A. Albrecht and E. J. O'Brien (1991) found that with narrative texts central concepts are more quickly retrieved than peripheral concepts. In contrast, F. R. Yekovich and C. H. Walker (1986) found that when concepts are embedded within scripts, peripheral concepts are more quickly retrieved...
