Progesterone receptors (PR) are prognostic and predictive biomarkers in hormone-dependent cancers. Two main PR isoforms have been described, PRB and PRA, that differ only in that PRB has 164 extra N-terminal amino acids. It has been reported that several antibodies empirically exclusively recognize PRA in formalin-fixed paraffin-embedded (FFPE) tissues. To confirm these findings, we used human ...

Importance Measures (IMs) are used to rank the risk contributing factors in Probabilistic Risk Assessment (PRA). In this paper, existing IM methodologies are analyzed in order to select the most suitable IM for an Integrated PRA (IPRA) of Nuclear Power Plants. In IPRA, the classical PRA of the plant is used, but specific areas of concern (e.g., fire, GSI-191, organizational factors, and seismic...

pSAM2 is a site-specific integrative element from Streptomyces ambofaciens. The pra gene described earlier as an activator of pSAM2 replication is shown here to be also involved in the activation of its integration and excision. This was evidenced with derivatives of pSAM2 mutant B3 in which the pra gene was placed under the control of the inducible tipAp promoter. Transformation of Streptomyce...

Acute and chronic antihypertenslve effects of the angiotensin conferring enzyme inhibitor, captoprii (SQ 14,225), was assessed in 29 consecutirely-studled patients with hypertension. (Mean arterial pressure, 110-160 mm Hg). Eighteen patients had essential hypertension (three with high plasma renln activity (PRA), 11 with normal PRA, four with low PRA); eight had renovascular hypertension (four ...

The effect of indomethacin or placebo on aldosterone, plasma renin activity (PRA), sodium excretion, and urinary prostaglandin (PG) levels was investigated in five hypertensive subjects in 100 mEq sodium balance who had experienced malignant hypertension with a disturbance of their renin-aldosterone relationship in the past. Indomethacin significantly lowered aldosterone levels by 43%, PRA by 5...

The aim of the present study was to investigate the possibility that catecholaminergic pathways within the central nervous system play a role in the control of renin secretion. Plasma renin activity (PRA) was measured after intravenous administration of L-dopa with and without prior inhibition of extracerebral dopa decarboxylase by carbidopa (MK-486) in pentobarbital-anesthetized dogs in which ...

Pretransplantation panel reactive antibody (PRA) testing assesses posttransplantation risk for antibody-mediated graft injury. It was postulated analogously that screening for effector/memory alloreactive T cells by "panel of reactive T cells" (PRT) using IFN-gamma enzyme-linked immunosorbent spot assays would evaluate independently cellular alloimmunity in transplant candidates. Peripheral blo...

OBJECTIVE Although many methods for pain assessment in newborns are available, none of them are widely accepted. Our aim was to answer the question: do newborns respond similarly to different painful procedures? METHODS Sixty term newborns were involved in non-randomized prospective study. They were classified into 2 groups: Group A (n=30) who needed intubation and Group B (n=30) who necessit...

The purpose of this investigation was to assess the effects of acute hypoxia on left (LV) and right ventricular (RV) contractility in clinically stable chronic obstructive pulmonary disease (COPD) patients. Eleven male patients (mean age 52.4 +/- 12.6 years) who were diagnosed to have COPD were included into the study. All of the patients underwent left and right heart catheterization. RV contr...

Background. Laparoscopic lateral transperitoneal adrenalectomy (LTA) has been the standard method for resecting benign adrenal gland tumors. Recently, however, laparoscopic posterior retroperitoneal adrenalectomy (PRA) has been more popular as an alternative method. This systematic review evaluates current evidence on adrenalectomy techniques, comparing laparoscopic LTA with PRA and laparoscopi...
