OBJECTIVES This study describes changes in high-frequency QRS components (HF-QRS) during percutaneous transluminal coronary angioplasty (PTCA) and compares the ability of these changes in HF-QRS and ST-segment deviation in the standard 12-lead electrocardiogram (ECG) to detect acute coronary artery occlusion. BACKGROUND Previous studies have shown decreased HF-QRS in the frequency range of 150–

Angiogenesis and increased permeability of the blood-brain barrier have been reported to occur in animal models of Parkinson's disease and l-dopa-induced dyskinesia, but the significance of these phenomena has remained unclear. Using a validated rat model of l-dopa-induced dyskinesia, this study demonstrates that chronic treatment with l-dopa dose dependently induces the expression of vascular end

BACKGROUND:: Flow cytometry allows the use of several antibodies in addition to light scatter, and most flow cytometers will provide at least seven measurements on each cell passing through the laser beam. A skilled microscopist will classify at least 14 cell classes in bone marrow or blood. Our goal was to use the seven parameters available in our flow cytometer to provide a reliable differential

BACKGROUND: Higher operative risks after pneumonectomy for non-small cell lung cancer (NSCLC) have been reported after neoadjuvant chemotherapy or radiotherapy, or both. Patients who underwent pneumonectomy for NSCLC were evaluated for effect of neoadjuvant treatment on mortality and morbidity, especially bronchopleural fistula. METHODS: Between 1996 and 2003, 130 consecutive patients underwent pn

For hemophilia patients with inhibitors, immune tolerance induction (ITI) may help to restore clinical response to Factor (F) VIII or FIX concentrates. Several ITI regimens and protocols exist; however, despite 30 yr of progressive investigation, the ITI evidence base relies mainly on observational data. Expert opinion, experience, and interpretation of the available evidence are therefore valuabl

OBJECTIVE: To investigate the significance and pathogenic potential of a highly conserved major type II collagen triple-helical epitope-specific antibody (U1; amino acids 494-504) in vivo and in vitro in patients with early rheumatoid arthritis (RA) and in experimental animal models of collagen-induced arthritis (CIA). METHODS: U1-specific antibodies in sera from patients with early RA (with or wi

BACKGROUND: There is mounting evidence that children born after in vitro fertilization (IVF) run an increased risk of neurological complications and notably cerebral palsy. Whether developmental disturbances occur more often than expected is debated. AIM: To investigate the risk for ADHD in children conceived after IVF. METHODS: Children conceived after IVF and born between 1982 and 2005 were iden

Objectives: To assess the usefulness of hand function measurements in a study of treatment effects of tumour necrosis factor (TNF) blockers and to define the relationship between different hand function tests and also relate hand function to general disability and disease activity. Methods: The study group consisted of 49 patients with established rheumatoid arthritis (RA) who were followed for 1

The importance of tyrosine residues in ligand-mediated endocytosis of the platelet-derived growth factor beta-receptor was analyzed using a series of tyrosine residue-mutated beta-receptors, which together cover all of the tyrosine residues in the juxtamembrane segment, the kinase insert, and the carboxyl-terminal tail; also certain of the tyrosine residues within the first and second parts of the

Histamine in the rat stomach resides in enterochromaffin-like (ECL) cells and mast cells. The ECL cells are peptide-hormone-producing endocrine cells known to release histamine and chromogranin-A-derived peptides (such as pancreastatin) in response to gastrin. Ischemia (induced by clamping of the celiac artery or by gastric submucosal microinfusion of the vasoconstrictor endothelin) mobilizes larg

The psychometric properties of the three-item Minimal Insomnia Symptom Scale (MISS) were evaluated using the classical test theory. Different cut-offs for identifying insomnia were suggested in two age groups (≥6 and ≥7 among adult and elderly people, respectively). The aim of the present study was to test the measurement properties of the MISS using the Rasch measurement model, with special empha

It is speculated that virtual environments (VE) might be used as a training tool in brain injury rehabilitation. The rehabilitation process often involves practicing so-called instrumental activities of daily living (IADL), such as shopping, cooking, and using a telephone. If a brain injury patient is to practice such activities in a VE, the patient must be able to navigate the viewpoint and inter

To describe changes in the epidemiology of out-of-hospital cardiac arrest in Sweden with the emphasis on the younger age groups.
