  2. 1. Metabolic aspects of cardiac arrhythmias

    Author : Sigfus Gizurarson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiologi; Electrofysiologi; Djurexperiment; Metabolism;

    Abstract : Cardiac arrhythmias are an important cause of mortality and morbidity in patients with cardiac diseases. Sudden death due to ventricular tachycardia and fibrillation (VT/VF) in the setting of acute myocardial infarction (AMI) and heart failure (HF) is a frequent cause of premature death. READ MORE

  4. 2. The Role of Impaired Interatrial Conduction in Paroxysmal Atrial Fibrillation

    Author : Pyotr Platonov; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electrophysiology; Cardiovascular system; anatomy; interatrial conduction; lone atrial fibrillation; Kardiovaskulära systemet;

    Abstract : The aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the presence of double-peaked configurations of P-wave spatial magnitude in patients with lone paroxysmal AF compared with healthy individuals (I), suggesting the presence of interatrial conduction delays localised in the posterior-inferior interatrial route.

  5. 3. Renal dysfunction in orthopaedic surgery - with special reference to drug effects in the elderly

    Author : Görel Nergelius; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; protein HC; IgG; albumin; pharmacokinetics; diclofenac; clearance; elderly; penicillin; isoxazolyl; tubular; glomerular; arthroplasty; exercise; traumatology; Kirurgi; ortopedi; traumatologi; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

    Abstract : Total hip replacement (THR) is a common procedure, generally performed in elderly persons. Previous studies indicated that the use of isoxazolyl penicillins could induce a transient post-operative renal dysfunction in these patients. READ MORE

  6. 4. Alkaline Sphingomyelinase; A Potential Inhibitor in Colorectal Carcinogenesis

    Author : Erik Hertervig; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; oncology; Cytology; Gastroenterologi; Gastro-enterology; HT-29; MIN mouse; FAP; colorectal cancer; human; alkaline sphingomyelinase;

    Abstract : Sphingomyelin (SM) is present both in eucaryotic cells and the diet. Sphingomyelinase (SMase) hydrolyses SM and generates ceramide that has been implicated in the regulation of cell growth, differentiation and apoptosis. Previously a SMase with alkaline pH optimum was identified in the intestinal tract. READ MORE

  7. 5. Endothelial and cardiac effects of 5-fluorouracil. An experimental and clinical study

    Author : Sara Kinhult; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; oncology; Cytology; endothelin; onkologi; Cytologi; cancer; von Willebrand factor; thrombomodulin; lipoperoxidation; probucol; low-molecular weight heparin; scanning electron microscopy; 5-fluorouracil; endothelium;

    Abstract : The cytostatic drug 5-fluorouracil (5-FU) has been shown to affect both morphology and function of vascular endothelium. These effects could be part of the pathophysiology for 5-FU induced cardiotoxicity. The present thesis explores the mechanisms of this endothelial toxicity. READ MORE
