Additionally, any modification in vasoactive medication due to BP

Additionally, any modification in vasoactive medication due to BP derangement in the postoperative period was noted. Due check details to non-normal distribution of BRS, HR, and TPR samples, all measured values were expressed as medians with interquartile

range (IQR), and a nonparametric test (Friedman) was performed. After adjustment for multiple testing, differences were considered statistically significant when the two-tailed P value was less than.0036.

Results: Thirty-five patients (mean age, 71 years) with symptomatic or asymptomatic internal carotid artery stenosis were included. The BRS significantly decreased to a lower level 24 hours after surgery (4.71 ms/mm Hg [3.02-6.1]) than preoperatively (5.95 ms/mm Hg [4.68-10.86]; P < .0001), resulting in a within-patient difference of -2.46 ms/mm Hg (95% confidence interval [CI], -8.38–1.52). This difference (95%

CI, [-1.58(-8.24--0.80)]) persisted at the 72-hour measurements (5.63 ms/mm Hg [3.23-7.69]; P = .0005). The HR, reflecting the sympathetic activity, increased 24 hours after the operation (69 bpm [61.3-77.7]) compared with preoperative values (63 bpm [57.9-73.2]; P = .005) (within-patient difference [95% CI] 3.7 [1.5-8.5]), and this increase reached significance at 72 hours (69 bpm [65.4-77.5]; P = .001) (within-patient difference [95% CI] 5.5 [2.3-8.8]). Values of systolic pressure, diastolic pressure, mean arterial pressure, CO, and TPR were not significantly Crenolanib different between pre- and postoperative measurements. Overall, 23 (66%) patients developed significant postoperative hypertension requiring aggressive management with additional medications.

Conclusions: E-CEA might have a decreasing influence on BRS, leading to increased sympathetic activity. Investigations of the longer-term effects of impaired BRS are warranted. These findings should be interpreted with caution, noting the limitation of an absent control group. (J Vasc Surg 2012;55:1322-8.)”

pathogenicity of Listeria monocytogenes is related to its ability of invading and multiplying in eukaryotic cells. Its main virulence factors are now well characterized, but limited proteomic data is available concerning its adaptation to the intracellular environment. In this study, L. monocytogenes AMP deaminase EGD (serotype 1/2a) grown in human THP-1. monocytes (24h) were successfully separated from host organelles and cytosolic proteins by differential and isopycnic centrifugation. For control, we used cell homogenates spiked with bacteria grown in broth. Proteomes from both forms of bacteria were compared using a 2-D-DIGE approach followed by MALDI-TOF analysis to identify proteins. From 1684 distinct spots, 448 were identified corresponding to 245 distinct proteins with no apparent contamination of host proteins.
