Superoxide anion contributes to the pathogenesis of various forms of hypertension, but its role in the development of malignant hypertension remains unclear. The present study was performed to determine the influence of superoxide anion on blood pressure and renal hemodynamics in transgenic rats with inducible malignant hypertension [strain name: TGR(Cyp1a1Ren2)]. Malignant hypertension was ind...

The present study was designed to determine whether renal prostaglandins are involved in the renal vasodilation evoked by angiotensin II inhibition in sodium depletion. The converting enzyme inhibitor (CEI) captopril was administered to sodium-depleted control dogs and sodiumdepleted dogs that had previously received the inhibitors of prostaglandin synthesis, indomethacin or meclofenamate. CEI ...

The current standard-of-care for chronic hepatitis C viral infection is treatment with pegylated interferon (PegIFN) plus ribavirin for 24 to 48 weeks. Approximately 50% of HCV-infected patients achieve a sustained viral response (SVR) to this treatment. However, the remaining patients either respond during treatment but relapse upon treatment cessation, respond minimally, or do not respond at ...

Heme oxygenase-1 (HO-1) is induced by oxidative stress and plays an important role in protecting the kidney from oxidant-mediated damage in the streptozotocin (STZ) rat model of type-1 diabetes mellitus (DM-1). HO-derived metabolites, presumably carbon monoxide (CO), mediate vasodilatory influences in the renal circulation, particularly in conditions linked to elevated HO-1 protein expression o...

Type I interferons (IFNs) play an important role in antiviral immunity as well as immunopathogenesis of diverse chronic viral infections. However, the precise mechanisms regulating the multifaceted effects of type I IFNs on the immune system and pathological inflammation still remain unclear. In order to assess the immunological dynamics associated with rapid viral clearance in chronic hepatiti...

Abstract Research Question Can police increase victim satisfaction and improve efficiency by providing consenting domestic abuse victims, if their offenders are not present , with an immediate video link to a uniformed officer, rather than waiting for face-to-face attendance? Data Eligible cases this block-randomised trial ( N =517) included 357 calls from female victims of intimate partner vio...

BACKGROUND We evaluated the cerebral hemodynamics in childhood moyamoya disease patients before and after surgery to assess both surgical indication and the effect of revascularization using single photon emission computed tomography (SPECT) study with N-isopropyl-p-123I-iodoamphetamine (IMP). We compared results of quantitative and semi-quantitative SPECT studies to determine parameters by the...

The optimal duration of treatment with pegylated interferon (PEG-IFN) plus ribavirin (RBV) in patients with hepatitis C virus (HCV) genotype 6 is unknown. This study was aimed at determining treatment response on the basis of rapid virological response (RVR) of HCV genotype 6 in comparison with genotypes 1 and 3. Sixty-six treatment naïve patients were treated with PEG-IFN-α2a (180 μg/week) plu...

Low rates of angiotensin II (Ang II) infusion raise blood pressure, renal vascular resistance (RVR), NADPH oxidase activity, and superoxide. We tested the hypothesis that these effects are ameliorated by extracellular superoxide dismutase (EC-SOD). EC-SOD knockout (-/-) and wild type (+/+) mice were equipped with blood pressure telemeters and infused subcutaneously with Ang II (400 ng/kg per mi...

background rapid virological response (rvr) strongly predicts sustained virological response (svr) in patients with chronic hepatitis c (chc), and abbreviates antiviral therapy in some patients. objectives to identify factors predicting virological relapse (vr) in chc patients who attained rvr. patients and methods medical records of 133 chc patients with an rvr after completing 24 weeks of ant...
