Results: The mean maximal diameter of AAAs at 30

days was significantly lower in the treated group P compared with the control group C (2.5 +/- 1.0 vs. 4.9 +/- 2.1 mm; P < 0.01). The expansion rate of AAAs after 30 days was significantly reduced in group P compared with group C (36 +/- 14% vs. 67 +/- 23%; P < 0.01). Pro-MMP9 and MMP9 activities were significantly decreased in relative intensity (RI) in group P compared with group C (0.43 +/- 0.64 RI vs. 1.02 +/- 0.61 RI, P = 0.01; 0.18 +/- 0.57 RI vs. Autophagy inhibitor manufacturer 0.66 +/- 1.19 RI, P = 0.004). The activation rate of MMP2 was also significantly lower in group P compared with group C (1.27 +/- 0.42 vs. 1.67 +/- 0.44; P = 0.002). Elastase and plasmin tissue activities were significantly lower in group P compared with group C, respectively (3.9 +/- 3.3 vs. 5.8 +/- 3.7 IF min(-1) g(-1),and 25.9 +/- 23.9 vs. 49.1 +/- 38.7 IF min(-1) g(-1); P < 0.05).

Conclusion: After 30 days of treatment by perindopril, a significant decrease in aneurysmal degeneration of the decellularised aortic xenograft AAA model was observed. This phenomenon appears to be induced by a downregulation of enzymes involved in the aortic wall remodelling during aneurysmal degeneration.

“Background: Thrombolytic treatment with intravenous (IV) recombinant tissue plasminogen

activator (rtPA; 0.90 mg/kg, with a maximum dose of 90 mg) has been recommended as the standard management

for acute ischemic stroke (AIS) thrombolysis. However, the dose of IV rtPA in Asia remains controversial. Methods: This study was designed to verify the safety and efficacy of IV rtPA treatment for AIS with a lower dosage (0.90 mg/kg, with a maximum dose of 50 mg). Patients were divided into 3 dosage groups according to body weight (BW): group 1, <55 kg for 0.90mg/kg; group 2, 55 to 67 kg for 0.75 to 0.90mg/kg; and group 3, >67 kg for <0.75 mg/kg. The following data were collected: patient demographics, vascular risk factors, neuroimaging results, time of rtPA administration, National Institutes of Health Stroke Scale score Pinometostat before treatment and at 24 hours, and a modified Rankin Scale (mRS) score at 3 months. Results: Eighty-three AIS patients who were of Han Chinese descent were included in the study. The baseline characteristics of the 3 dosage groups were well matched. In group 1 (BW, 55 kg for 0.90 mg/kg; n=19), 57.1% had a favorable outcome at 3 months, compared with 61.2% of patients in group 2 (BW 55-67 kg for 0.75-0.90 mg/kg; n = 33) and 51.5% in group 3 (BW > 67 kg for <0.75 mg/kg; n = 31; P = .362). There were no significantly statistical differences in the incidence of symptomatic intracerebral hemorrhage and mortality rate. Conclusions: This IV rtPA regimen (0.
