OBJECTIVE These studies were undertaken to characterize the subcellular localization of the two major isoforms of progesterone receptors (PR), PRA and PRB, in endometrial cancer. METHODS Immunohistochemistry, immunoprecipitation, and confocal microscopy were performed using Hec50co and KLE endometrial cancer cell models expressing PRA or PRB as a consequence of transduction. The location of P...

Intraoperative blood requirements were analyzed in patients undergoing primary orthotopic liver transplantation and divided into two groups on the basis of panel reactive antibody of pretransplant serum measured by lymphocytotoxicity testing. One group of highly sensitized patients (n = 25) had PRA values of over 70% and the second group of patients (n = 26) had 0% PRA values and were considere...

An inactive precursor form of proteinase A (PrA) transits through the early secretory pathway before final vacuolar delivery. We used gene fusions between the gene coding for PrA (PEP4) and the gene coding for the secretory enzyme invertase (SUC2) to identify vacuolar protein-sorting information in the PrA precursor. We found that the 76-amino-acid preprosegment of PrA contains at least two sor...

INTRODUCTION Both atorvastatin and mycophenolate mofetil (MMF) have been used for panel reactive antibodies (PRA) reduction in transplant candidates. The purpose of this study was to compare the effect of low-dose MMF and atorvastatin on PRA in sensitized hemodialysis patients waiting for kidney transplantation. MATERIALS AND METHODS A total of 40 adult patients with end-stage renal disease w...

BACKGROUND Prospective risk analysis (PRA) is a valuable instrument in quality assurance. The practical application of PRA in clinical laboratories according to the method we have described elsewhere leaves room for a number of adaptations to make it more applicable to and consistent with actual laboratory processes. METHODS We distinguished between more and less critical tests and products i...

PURPOSE To screen the alpha-subunit of cyclic guanosine monophosphate (cGMP) phosphodiesterase (PDE6A) as a potential candidate gene for progressive retinal atrophy (PRA) in the Cardigan Welsh corgi dog. METHODS Single-strand conformation polymorphism (SSCP) analysis was used to screen short introns of the canine PDE6A gene for informative polymorphisms in members of an extended pedigree of P...

OBJECTIVES Emergency admission is associated with the potential for adverse events in older people and risk prediction models are available to identify those at highest risk of admission. The aim of this study was to externally validate and compare the performance of the Probability of repeated admission (Pra) risk model and a modified version (incorporating a multimorbidity measure) in predict...

Previous workers have suggested that a rise in plasma renin activity (PRA) may mediate some of the hemodynamic changes associated with exercise. To test this hypothesis in nine dogs chronically instrumented for measurement of aortic pressure (catheter) or cardiac output (ascending aorta electromagnetic flow probe) PRA was measured by radioimmunoassay in blood samples drawn before and during run...

Twenty-one healthy newborn infants whose mothers had normal pregnancies and deliveries were studied. Plasma renin activity (PRA) and plasma aldosterone concentration (PAldo) were measured by semimicro methods in cord blood and on the 6th day of life. PRA and PAldo were increased in cord blood compared with values previously found in healthy infants between 1 month and 1 year of age. There was a...
