Background: Activation of nuclear factor-kappaB (NF-kappaB) is one of the key events in early atherosclerosis and restenosis. We hypothesized that tumor necrosis factor-alpha (TNF-alpha) induced and NF-kappaB mediated expression of intercellular adhesion molecule-1 (ICAM-1) can be inhibited by antisense RelA p65 and NF-kappaB1 p50 oligonucleotides (RelA p65 and NF-kappaB1 p50).

Results: Smooth muscle cells (SMC) from human coronary plaque material (HCPSMC, plaque material of 52 patients), SMC from the human coronary media (HCMSMC), human endothelial cells (EC) from umbilical veins (HUVEC), and human coronary EC (HCAEC) were successfully isolated (HCPSMC, HUVEC), identified and cultured (HCPSMC, HCMSMC, HUVEC, HCAEC).

With the introduction of the maze operation Cox was able to show that the surgical treatment of atrial fibrillation (AF) is feasible. However, the maze operation remains surgically demanding and time-consuming as it requires multiple incisions in both atria. This has led to the development of various modifications.

Background: The excellent results of the Cox-Maze-III operation showed that a surgical treatment of atrial fibrillation is possible. The maze operation is surgically demanding and time-consuming. This fact led to the development of simplified modifications.

Background: Because of the beneficial effects of estrogen, premenopausal women are normally protected against coronary heart disease (CHD) and are at lower risk for myocardial infarction; consequently, CHD occurs very rarely in menstrually active women. Given this background, the aim of the present study was to test the hypothesis that decreased concentrations of estrogen are associated with CHD in premenopausal women.

Methods: Fourteen premenopausal women with CHD were investigated and compared with a healthy control group comparable for age and cardiovascular risk factors.

To compare the negative inotropic effects of the four dihydropyridine-calcium-channel-blockers nifedipine (NIF), isradipine (ISR), nisoldipine (NIS) and felodipine (FEL) in man, the drugs were infused within 30 min intravenously in an equihypotensive dosage (NIF 2 mg, ISR 0.5 mg, NIS 0.5 mg, FEL 0.
