Primary aldosteronism is a disorder with hypertension, hypokalemia, increased plasma aldosterone, and suppressed renin activity. A random plasma aldosterone/renin activity (PA/PRA) >65 (conventional units ratio [CUR] >30) has been proposed as a screening test. We have retrospectively determined the value of the post-captopril plasma aldosterone/renin activity (CAPT PA/PRA) test for the diagnosi...

Traditional probabilistic risk assessment (PRA), of the type originally developed for engineered systems, is still proposed for terrorism risk analysis. We show that such PRA applications are unjustified in general. The capacity of terrorists to seek and use information and to actively research different attack options before deciding what to do raises unique features of terrorism risk assessme...

AIMS Plasma renin activity (PRA) has been shown to predict future cardiovascular (CV) events in observational studies and in clinical trials and to be associated with the prevalence of chronic renal disease in hypertensive subjects. In a nested case-control study, we explored the relationship between CV and renal outcomes and all-cause mortality with baseline measurements of PRA among hypertens...

plasma renin activities (PPA) were measured before treatment and 5 weeks and 10 weeks after the beginning of the administration of the above-mentioned diet. The data were compared with those of non-treated age-matched SHR controls. Each group consisted of more than 8 SHRs and blood samples were taken immediately after decapitation. PCA was measured by double isotope derivative method and PRA by...

PETTINGER, WILLIAM A., MARY MARCHELLE, AND LORAINE A~GUSTO. Renin suppression by DOC and NaCl in the rat. Am. J. Physiol. 221(4) : 1071-1074. 197 1 .-Endocrine and dietary changes known to alter plasma renin activity (PRA) were studied in the nonanesthetized rat. Deoxycorticosterone (DOC) suppressed PRA by 90-95%. Ingestion of a low-sodium diet elevated PRA from a mean control value of 120 to 5...

PURPOSE To examine the relationship between relative accommodation and general binocular disorders and to establish their importance in the diagnosis of these anomalies. METHODS We analyzed data of negative relative accommodation (NRA) and positive relative accommodation (PRA) in 69 patients with nonstrabismic binocular anomalies. RESULTS Statistical analysis showed that low values of NRA a...

Circadian changes in plasma renin activity (PRA) and plasma aldosterone concentration (PAC) in normal and hypertensive rats were determined by measurements at 8 a.m., 4 p.m. and 12 midnight (MN). For the normals, PRA and PAC were highest at 4 p.m. Animals made hypertensive by constriction one renal artery with the other kidney intact were studied after 4, 5, 7 and 10 weeks; the clear-cut circad...

Mechanical ventilation with positive end-expiratory pressure (PEEP) may prevent venous air embolism in the sitting position because cerebral venous pressure (Pcev) could be increased by the PEEP-induced increase in right atrial pressure (Pra). Whereas it is clear that there is a linear transmission of the PEEP-induced increase in Pra to Pcev while the dog is in the prone position, the mechanism...

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 ...

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...
