Effect of NaCl on protein and lipid oxidation in frozen yellowtail meat.

Protein carbonyl (PC) and malonaldehyde (MA) contents and protein extractability (PE) in yellowtail meat containing NaCl stored at -20 degrees C for 20 weeks were analyzed. Although the PC and MA contents increased in all samples, the PE value decreased in the samples containing NaCl. After 20 weeks of storage, the protein (approximately 97.

Risk factors associated with perioperative myocardial damage in patients with severe aortic stenosis.

Aim: Few studies have been performed about the risk factors associated with perioperative myocardial damage in patients undergoing valve surgery for severe aortic stenosis.

Methods: To assess the prevalence of perioperative myocardial damage, we studied 103 consecutive patients with aortic stenosis. Perioperative myocardial damage (PMD) was diagnosed by both enzymatic data of peak creatine kinase iso-enzyme (CK-MB) and new appearance of electrocardiographic abnormality.

Influence of St. Jude medical valve in patients with aortic stenosis and small aortic annulus on cardiac function and late survival result.

This clinical study analyzes our experience of postoperative cardiac function and long-term survival rate in patients with aortic stenosis and small-size St. Jude Medical (SJM) valve. Sixty-eight patients who underwent aortic valve replacement by SJM valve were divided into two groups by preoperative aortic annulus diameter.

Correlation between age and vital organ function following deep hypothermic circulatory arrest.

Background: We investigated the correlation bet-ween perioperative variables such as patients' age and vital organ function after operation on thoracic aorta using deep hypothermic circulatory arrest (DHCA).

Methods: Ninety-five patients who underwent replacement of thoracic aorta under DHCA for acute or chronic aortic dissection and aortic aneurysm, and survived more than 10 days were divided into group I (age less than 60, n=17), group II (between 60 and 69, n=39), and group III (over 70, n=39). Concomitant procedures such as aortic root replacement and coronary artery bypass grafting were performed in 9, 4, and 1 patients in group I, II, and III, respectively.

Systemic hypertension as a risk factor for complications with an aortic mechanical valve.

We sought to determine the effect of preoperative systemic hypertension on prosthesis related complications or postoperative aortic dissection after valve replacement in patients with aortic regurgitation. The patients were divided into two groups according to the presence or absence of systemic hypertension: Group I, with hypertension (n = 35), and Group II, without hypertension (n = 37). The survival rate and event free rate were examined for 72 patients who were alive 30 days after valve replacement with a St.
