question:
Cardiac rupture is a catastrophic complication that occurs after acute myocardial infarction (MI) and, at present, there are no effective pharmacological strategies for preventing this condition. Here we investigated the effect of the angiotensin II receptor blocker olmesartan (Olm) on post-infarct cardiac rupture and its underlying mechanisms of action.', 'C57Bl/6 mice with MI were treated with Olm, aldosterone (Aldo) or vehicle. Cultured neonatal cardiomyocytes and fibroblasts were exposed to normoxia or anoxia and treated with angiotensin II (Ang II), RNH6270 (active ingredient of Olm) or Aldo.', 'The mortality rate and incidence of cardiac rupture in MI mice during the first week in the Olm-treated group were significantly lower than in the vehicle-treated group. Olm or RNH6270 reduced myeloperoxidase staining in the infarcted myocardium, decreased apoptosis in cultured cardiomyocytes and fibroblasts, as assessed by Hoechst staining and TUNEL assay, attenuated the accumulation of p53 and phosphorylated p53 and cleaved caspase 3 induced by MI or Ang II, as assessed by Western blotting, and up-regulated growth differentiation factor-15 (GDF-15). In cultured cardiomyocytes and fibroblasts, treatment with Ang II, Aldo or anoxia significantly down-regulated the expression of GDF-15.
answer:
Does olmesartan prevent cardiac rupture in mice with myocardial infarction by modulating growth differentiation factor 15 and p53?

question:
Recent studies have suggested that the percent of positive cores in the prostate needle biopsy is a significant predictor of outcome among men undergoing radical prostatectomy or radiation therapy for prostate cancer. We evaluate whether either percent of cores with cancer or percent of cores positive from the most and least involved side of the prostate needle biopsy was associated with a worse outcome among men treated with radical prostatectomy.', 'A retrospective survey of 1,094 patients from the SEARCH Database treated with radical prostatectomy at 4 different equal access medical centers in California between 1988 and 2002 was undertaken. We used multivariate analysis to examine whether total percent of prostate needle biopsy cores with cancer, percent of cores positive from each side of the prostate and other clinical variables were significant predictors of adverse pathology and time to prostate specific antigen (PSA) recurrence following radical prostatectomy.', 'On multivariate analysis serum PSA and percent of positive cores were significant predictors of positive surgical margins, nonorgan confined disease and seminal vesicle invasion. Percent of positive cores (p <0.001), serum PSA (p = 0.008) and biopsy Gleason score (p = 0.014) were significant independent predictors of time to biochemical recurrence. On a separate multivariate analysis that included the variables of total percent of positive cores, percent of positive cores from the most involved side of the biopsy, percent of positive cores from the least involved side of the biopsy and whether the biopsy was positive unilaterally or bilaterally, only the percent of positive cores from the most involved side of the biopsy was a significant independent predictor of PSA failure following radical prostatectomy. Percent of positive cores was used to separate patients into a low risk (less than 34%), intermediate risk (34% to 50%) and high risk (greater than 50%) groups, which provided significant preoperative risk stratification for PSA recurrence following radical prostatectomy (p <0.001). Percent of positive cores cut points were able to further risk stratify men who were at low (p = 0.001) or intermediate (p = 0.036) but not high (p = 0.674) risk for biochemical failure based on serum PSA and biopsy Gleason score.
answer:
Is percent of prostate needle biopsy cores with cancer significant independent predictor of prostate specific antigen recurrence following radical prostatectomy : results from SEARCH database?

question:
To investigate the effects of angiotensin converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) and other anti-hypertensive agents on recombinant human erythropoietin (rHuEPO) in chronic renal failure (CRF) patients.', "The present study was conducted at the Nephrology Department, Khan Research Laboratories Hospital and Quaid-i-Azam University, Islamabad, Pakistan during March 2004 to February 2005. One hundred patients, 55 males and 45 females (age range 13-78 years) were divided into 2 groups. Group-I patients received rHuEPO and ACE inhibitors/ARBs while Group-II patients received rHuEPO with other antihypertensives such as calcium channel blockers or beta-adrenergic receptor blockers. Monthly increment in hematocrit (HCT%) was monitored in both groups for 4 continuous months. One-way ANOVA on Dunn's, univariate and multivariate analyses were carried out to determine any significant improvement in erythropoiesis between the 2 treatment groups.", 'Monthly increase in HCT% was significantly greater in the group that was treated with rHuEPO and antihypertensives other than ACE inhibitors/ARBs compared with that treated with ACE inhibitors/ARBs, an effect observed even at a higher dose of rHuEPO, and the patients were iron replete.
answer:
Do angiotensin converting enzyme inhibitors impair recombinant human erythropoietin induced erythropoiesis in patients with chronic renal failure?
