BACKGROUND Heart failure can result from a variety of causes, including ischemic, hypertensive, toxic, and inflammatory heart disease. However, the cellular mechanisms responsible for the progressive deterioration of myocardial function observed in heart failure remain unclear and may result from apoptosis (programmed cell death). METHODS We examined(More)
BACKGROUND The aim of the present study was to investigate whether Ca2+ uptake into the sarcoplasmic reticulum (SR) is altered in failing human myocardium resulting from dilated cardiomyopathy. METHODS AND RESULTS Ca(2+)-ATPase (SERCA II) activity and Ca(2+)-dependent 45Ca2+ uptake (oxalate supported, steady state) in isolated vesicles from the SR (VSR)(More)
Down-regulation of E-cadherin, an intercellular adhesion molecule, and up-regulation of autocrine motility factor receptor (gp78) expressions have been shown to play a role in tumor cell invasion and metastasis. Monoclonal antibodies against E-cadherin and gp78 were used to stain serial snap-frozen sections of 12 normal bladder and 83 bladder carcinoma(More)
There is evidence that the failing human left ventricle in vivo subjected to additional preload is unable to use the Frank-Starling mechanism. The present study compared the force-tension relation in human nonfailing and terminally failing (heart transplants required because of dilated cardiomyopathy) myocardium. Isometric force of contraction of(More)
In human and experimental models of heart failure, sarcoplasmic reticulum Ca(2+) ATPase (SERCA2a) activity is decreased, resulting in abnormal calcium handling. The disturbances in calcium metabolism have been shown to contribute significantly to the contractile dysfunction observed in heart failure. We investigated whether increasing SERCA2a expression can(More)
PURPOSE There is a growing amount of data suggesting that carcinomas of the right and left colon should be considered as different tumor entities. Using the data and analysis compiled in the German multicentered study "Colon/Rectum Cancer," we aimed to clarify whether the existing differences influence clinical and histological parameters, the perioperative(More)
BACKGROUND The aim of the present study was to analyze changes regarding the indications for and results of laparoscopic treatment of sigmoid diverticulitis. METHODS The data were collected within the framework of an ongoing prospective multicenter study carried out by the Lapa roscopic Colorectal Surgery Study Group and were submitted to a statistical(More)
Topically applied capsaicin (CAS 404-86-4) induces the release of substance P, a neurotransmitter, from sensory C-fibres. In addition, there is a specific blockade of transport and de-novo synthesis of substance P. As a result, repeated applications of capsaicin bring about a long lasting desensitisation to pain (increase of pain threshold). The(More)
The efficacy and tolerance of a garlic preparation (Sapec, Kwai) was investigated in a randomized double-blind study vs. bezafibrate. This multi-centre study was conducted in 5 general medical practices and involved 98 patients with primary hyperlipoproteinaemia. The daily doses of the active substances were 900 mg of garlic powder (standardized as to 1.3%(More)
