This paper seeks to develop a research proposal in the field of political risk assessment (PRA) in the context of the “Visegrad Four” countries. A literature review – both theoretical and empirical – is presented; based on which the research framework is developed. Previous studies are concerned mostly with PRA in the context of developed countries, and those in the context of transition and em...

In six inbred dogs with neonatally-induced coarctation hypertension, and in seven littermate controls, acute responses of proximal arterial pressure and plasma renin activity (PRA) to converting enzyme inhibitor (CEI; SQ 20,881, 0.5 mg/kg i.v.) were serially examined. Studies were performed at 2, 6, and 12 months post-aortic banding under sodium-replete and -deplete conditions. Both in normoten...

BACKGROUND Patients with panel reactive antibodies (PRA) have many difficulties to find a crossmatch-negative kidney for transplantation and are at a higher risk of post-transplantation rejection. OBJECTIVE To evaluate the effect of simvastatin on PRA and post-transplant outcome of these sensitized patients. METHODS 82 patients with end-stage renal disease (ESRD) with a PRA ≥25% were evalua...

We have assessed the influence of a mild emotional stimulus on arterial blood pressure, heart rate, renal blood flow, plasma renin activity (PRA), and plasma aldosterone concentration in 24 normal subjects, eight of who had a parent with hypertension, and in 15 patients with essential hypertension. A nonverbal IQ test, Raven's Progressive Matrices, was employed as the stimulus. In 11 of the 15 ...

BACKGROUND The ratio of plasma aldosterone concentration to plasma renin activity (PAC/PRA) is the most common screening test for primary hyperaldosteronism (PHA), but it is not standardized among laboratories. We evaluated new automated assays for the simultaneous measurement of PAC and plasma renin concentration (PRC). METHODS We studied 76 healthy normotensive volunteers and 28 patients wi...

BACKGROUND Chronic allograft rejection manifested as bronchiolitis obliterans syndrome (BOS) is the leading cause of late death after lung transplantation. Although increasing evidence suggests an association between anti-human leukocyte antigens (HLA) antibodies and chronic rejection of kidney or heart allografts, the clinical significance of anti-HLA antibodies in lung recipients is less clea...

PURPOSE Previously, a 44 bp insertion in exon 2 of retinitis pigmentosa GTPase interacting protein 1 (RPGRIP1) was identified as the cause of cone-rod dystrophy 1 (cord1), a recessive form of progressive retinal atrophy (PRA) in the Miniature Longhaired Dachshund (MLHD), a dog model for Leber congenital amaurosis. The cord1 locus was mapped using MLHDs from an inbred colony with a homogeneous e...

Product recommendation agents (PRA) are systems built to facilitate customers’ products purchase on e-commerce websites. Prior literature focuses on the “shaping” effects of PRA to customers’ decision making. More challengingly, PRA can be built to change customers’ product choice by combining with persuasive features. This paper explores this new type of PRA “persuasive product recommendation ...
