OBJECTIVE To assess the influence of air-polishing devices and various abrasives on flat root surfaces. METHOD AND MATERIALS A total of 168 natural teeth were embedded in polyurethane resin and treated with airborne-particle abrasion using two air-polishing devices (Prophyflex 3, KaVo; EMS Handy, EMS), four abrasives (Airflow powder, EMS; Cleaning powder,(More)
Macular pigment (MP) is believed to have a protective role in the development and progression of age-related maculopathy (ARM). We present results of measurements of macular pigment density (MPD) in patients with ARM at different stages with a modified confocal scanning laser ophthalmoscope (HRA, Heidelberg Engineering, Heidelberg, Germany). ARM patients(More)
The study presents a case of non-fatal poisoning with oleander blooms in a 47-year-old female, with emphasis on the importance of toxicological service in a clinical emergency. After repeated vomiting at home, the patient was admitted at the hospital with cardiac symptoms more than 18 h after the ingestion. Serum samples were assayed immunochemically for(More)
OBJECTIVE To assess the cardiac status of patients ten years after percutaneous transluminal coronary artery angioplasty (PTCA). PATIENTS AND METHODS Data of 534 patients (436 men, 98 women; mean age 53.2 +/- 8 years) in whom a PTCA had been performed between 1983 and 1986 were analysed, based on a questionnaire answered 121 +/- 11 months after the(More)
Sphingolipids are characterized by a broad range of bioactive properties. Particularly, the development of insulin resistance, a major pathophysiological hallmark of Type 2 Diabetes mellitus (T2D), has been linked to ceramide signaling. Since vitamin D supplementation may slow down T2D progression by improving glucose concentrations and insulin sensitivity,(More)
Percutaneous transluminal coronary angioplasty (PTCA) was performed in 14 patients with significant left main stem stenosis following protective coronary artery bypass grafting (CABG). The procedure was successful in 13/14 patients (93%), achieving a decrease in mean diameter stenosis from 74% +/- 7% to 31% +/- 12% (P less than 0.01). Accordingly, the(More)
Mesenchymal stem cells are known to exert immunomodulatory effects in inflammatory diseases. Immuneregulatory cells lead to progressive joint destruction in rheumatoid arthritis (RA). Proinflammatory cytokines, such as tumour necrosis factor α (TNF-α) and interleukins (ILs) are the main players. Here, we studied progenitor cells from RA cartilage (RA-CPCs)(More)
Varicella zoster virus (VZV) is a neurotropic human alphaherpes virus that causes varicella (chickenpox) initially and zoster upon reactivation of latent infection. In adults and immunocompromised patients, severe clinical complications can occur. In 1992, a new immunodeficiency syndrome called idiopathic CD4 T-cell lymphocytopenia (ICL) was first(More)
Loss of intestinal barrier functions is a hallmark of inflammatory bowel disease like ulcerative colitis. The molecular mechanisms are not well understood, but likely involve dysregulation of membrane composition, fluidity, and permeability, which are all essentially regulated by sphingolipids, including ceramides of different chain length and saturation.(More)
In the area of increasing interventional techniques there is a need for noninvasive imaging modalities to provide postinterventional follow-up. We were able to visualize the apparent patency and measure the dimensions of an intracoronary Palmaz-Schatz stent in the left circumflex coronary artery using transesophageal two-dimensional echocardiography. This(More)
