Congenital Adrenal Hyperplasia (CAH) is an adrenal disorders due to impaired activity of one of the enzymes required for cortisol and aldosterone biosynthesis. One of the subtypes of CAH is the salt-wasting (SW) form which there is a renal salt loss due to aldosterone deficiency. Plasma Renin Activity (PRA) is the main index used to evaluate the mineralocorticoid control in CAH. PRA testing is ...

Progesterone receptor (PR) and progestins affect mammary tumorigenesis; however, the relative contributions of PR isoforms A and B (PRA and PRB, respectively) in cancer cell migration remains elusive. By using a bi-inducible MDA-MB-231 breast cancer cell line expressing PRA and/or PRB, we analyzed the effect of conditional PR isoform expression. Surprisingly, unliganded PRB but not PRA strongly...

OBJECTIVE In this study, we aimed to investigate the incidence, dynamics and profiles of human leukocyte antigen (HLA)-directed antibodies developed after transplantation and their impact on graft rejection and outcome in kidney recipients. STUDY DESIGN Prospective follow-up study. MATERIAL AND METHODS A total of 56 kidney recipients were monitored at 1(st), 6(th) and 12(th) months for the ...

Introduction. Several studies have shown the feasibility and safety of both transperitoneal and posterior retroperitoneal approaches for single incision laparoscopic adrenalectomy, but none have compared the outcomes according to the left- or right-sided location of the adrenal glands. Materials and Methods. From 2009 to 2013, 89 patients who received LAMP (laparoscopic adrenalectomy through mo...

A correlation was found between the expression of a specific Mycoplasma fermentans surface antigen (Pra, proteinase-resistant antigen) and the site of isolation of the organism from the infected host. Strains which expressed Pra were most frequently associated with cells of bone marrow origin, and strains which lacked expression of Pra were most commonly isolated from the respiratory tract, gen...

introduction many studies have shown epidemiological links between strains isolated in tap water, and those isolated from patients. molecular methods linked to pcr are more reliable and faster for identification of             non- tuberculous mycobacteria(ntm). in this study molecular methods were used for identification and typing of ntm. materials and methods five hundred ml of 85 water samp...

Background Pravastatin (Pra) exerts protective effects on preeclampsia. Preeclampsia is a multifactorial and pathogenic pathway syndrome. The present study compared the effects of Pra on clinical manifestations of preeclampsia in different pathogenic pathways. Methods Two different preeclampsia-like mouse models used in this study were generated with Nω-nitro-L-arginine methyl ester (L-NAME) ...

To determine the effect of diabetes mellitus on the renin-aldosterone system, independent of age, nephropathy, or hypertension, 16 normotensive diabetics with long-term disease (mean duration, 15 years) and no (14) or minimal (2) proteinuria, were compared to nine age-matched, normotensive controls. Plasma renin activity (PRA) measured supine and after 4 hours of quiet ambulation, both on an ad...

This paper reviews the chronic effects of lead exposure on the renin-angiotensin system in experimental animals and human beings. In rats, when lead exposure is begun several weeks after birth in doses that cause blood lead concentrations (PbB) of 30 to 40 micrograms/dL, the result is an increase in basal plasma renin activity (PRA) and renal renin concentration, with no change in the metabolic...

In canine neonatally-induced coarctation hypertension, we reported abnormally elevated plasma renin activity (PRA) during sodium restriction in 2-year-old dogs, but found normal PRA responses to sodium restriction +/- furosemide in coarcted dogs studied serially over the first year postaortic banding (PAB). To resolve this apparent discrepancy in PRA response, longitudinal studies were extended...
