\n\n3. The birds stunned with N-2 displayed the highest initial reduction in muscle pH, but after 4 h post mortem there were no differences in pH values associated with the various CAS methods.\n\n4. The CAS method alone had no statistically significant effect on the quality of turkey breast muscle when the chilling speed was rapid (0 degrees C for 4 h, followed by storage at 4 degrees C). When the chilling rate BMS-754807 in vitro was slowed (20 degrees C for 4 h followed by storage at 4 degrees C), a significant decrease in cooking loss and in Warner-Bratzler shear force was recorded for birds stun-killed with
CO2.\n\n5. This study shows that anoxic stun-killing with N-2 had no adverse effects on meat quality despite the rapid post mortem pH decrease. The CAS with N-2 allows Quisinostat ic50 rapid cooling of carcases without the risk of cold shortening, whereas with CO2-stun-killing of turkeys, the rate of chilling should be slower. Concerning meat quality, all the CAS methods tested were suitable for stunning turkeys.”
“Epicardial adipose tissue is a source of pro-inflammatory
cytokines and has been linked to the development of coronary artery disease. No study has systematically assessed the relationship between local epicardial fat volume (EFV) and myocardial perfusion defects. We analyzed EFV in patients undergoing SPECT myocardial perfusion selleck compound imaging combined with computed tomography (CT) for attenuation correction. Low-dose CT without contrast was performed in 396 consecutive patients undergoing SPECT imaging for evaluation of coronary artery disease. Regional thickness, cross-sectional areas, and total EFV were assessed. 295 patients had normal myocardial perfusion scans and 101 had abnormal perfusion scans. Mean EFVs in normal, ischemic, and infarcted hearts were 99.8 +/- A 82.3 cm(3), 156.4 +/- A 121.9 cm(3), and 96.3 +/- A 102.1 cm(3), respectively (P smaller than 0.001). Reversible perfusion defects were associated with increased local EFV compared to normal
perfusion in the distribution of the right (69.2 +/- A 51.5 vs 46.6 +/- A 32.0 cm(3); P = 0.03) and left anterior descending coronary artery (87.1 +/- A 76.4 vs 46.7 +/- A 40.6 cm(3); P = 0.005). Our results demonstrate increased regional epicardial fat in patients with active myocardial ischemia compared to patients with myocardial scar or normal perfusion on nuclear perfusion scans. Our results suggest a 123 potential role for cardiac CT to improve risk stratification in patients with suspected coronary artery disease.”
