Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Prevention of intraabdominal abscess formation constitutes an important goal in treatment of secondary peritonitis. Fibrinolytic therapy may be effective in this respect. The efficacy of recombinant tissue plasminogen activator (rtPA) and urokinase is compared in a preclinical model for surgical treatment of peritonitis.', 'Peritonitis was induced by intraperitoneal bacterial challenge in male Wistar rats. After 1 hour, surgery was performed. Four groups (n = 20) were treated with one of the following: rtPA, urokinase, streptokinase (a negative protein control), or saline. Blood cultures were taken at 6 and 24 hours; cell counts and cytokine measurements were performed in peritoneal fluid at 1, 3 and 5 days. After 5 days, animals were killed and intraperitoneal abscess formation was analyzed.', 'Both rtPA and urokinase strongly (> 75%) and significantly (P < .05) reduced abscess formation without negative side effects. No bleeding complications were observed. Fibrinolytic therapy altered the intraperitoneal cellular distribution (less neutrophils and more macrophages) but did not essentially alter the courses of interleukin-6 and interleukin-10 (decreasing in time) or tumor necrosis factor-* (increasing in time) levels.
Do both tissue-type plasminogen activator and urokinase prevent intraabdominal abscess formation after surgical treatment of peritonitis in the rat?

Neuroblastoma is a common pediatric solid tumor with poor outcome for metastatic disease. Thus, novel therapeutic options are of main interest. The anti-neoplastic properties of taurolidine have been demonstrated on a variety of human cancer cells. However, data on neuroblastoma is lacking. Therefore, our aim was to evaluate the effect of taurolidine on growth of neuroblastoma cell lines.', 'Neuroblastoma SK-N-BE(2)-M17 and SK-N-SH cells and nonmalignant human umbilical vein endothelial cells as controls were incubated with increasing concentrations of taurolidine (100, 250, 500 M). Cell growth was examined after 12, 24, and 48 hours of exposure.', 'Inhibition of cell growth by taurolidine was seen in both malignant cell lines. When compared with human umbilical vein endothelial cells, the neuroblastoma cell lines were significantly more responsive to taurolidine.
Does taurolidine specifically inhibit growth of neuroblastoma cell lines in vitro?

Arterial stiffening and endothelial dysfunction are hallmarks of aging, and advanced glycation endproducts (AGE) may contribute to these changes. We tested the hypothesis that AGE crosslink breakers enhance endothelial flow-mediated dilation (FMD) in humans and examined the potential mechanisms for this effect.', 'Thirteen adults (nine men, aged 65 +/- 2 years) with isolated systolic hypertension (systolic blood pressure > 140 mmHg, diastolic blood pressure < 90 mmHg or pulse pressure > 60 mmHg) on stable antihypertensive therapy were studied. Subjects received placebo (2 weeks) then oral alagebrium (ALT-711; 210 mg twice a day for 8 weeks). Subjects and data analyses were blinded to treatment. Arterial stiffness was assessed by carotid augmentation index (AI) and brachial artery distensibility (ArtD) using applanation tonometry and Doppler echo, and endothelial function by brachial FMD. Serum markers of collagen metabolism and vascular inflammation were assessed.', 'Alagebrium reduced carotid AI by 37% (P = 0.007) and augmented pressure (16.4 +/- 10 to 9.6 +/- 9 mmHg; P < 0.001). Heart rate, arterial pressures, and ArtD, were unchanged. FMD increased from 4.6 +/- 1.1 to 7.1 +/- 1.1% with alagebrium (P < 0.05), and was unrelated to altered shear stress or regional arterial distensibility. However, FMD change was inversely related to markers of collagen synthesis, p-selectin and intracellular cell adhesion molecule (all P < 0.05). Alagebrium-associated changes in plasma nitrite plus nitrate was inversely correlated with plasma matrix metalloproteinase 9 and type I collagen (P = 0.007).
Does advanced glycation endproduct crosslink breaker ( alagebrium ) improve endothelial function in patients with isolated systolic hypertension?
