BACKGROUND Direct percutaneous transluminal coronary angioplasty (PTCA) is widely accepted in the treatment of acute myocardial infarction since excellent results had been reported from several small randomized trials. Less favourable results were observed in large-scale registries. In particular, the use of stents in acute myocardial infarction has become(More)
Low- and medium expressions of hyperostosis spongiosa orbitae are occurring rather frequently compared to strong or very strong ones, yet their notation and differentiation is sometimes rather difficult. By means of original photographs of low and medium intensity degrees of this pathological trait methodological facilitation of notation is intended. This(More)
Different aspects relevant for the assessment and characterization of biomaterials are presented. Quite a number of basic concepts that play an important role when detecting unwanted adverse effects of drugs have to be taken into consideration when registering and evaluating unwanted effects of biomaterials. The institutionalization of the Central(More)
Adhesion and aggregation are important parameters characterizing the function of intact platelets in flowing blood and in contact with a more or less thrombogenic surface. In the retention test Homburg (RTH), platelets are exposed to a standardized textured surface (Sysmex retention tubes) under defined conditions of flow. Platelet counts are performed(More)
Decreased retention in the retention test Homburg (RTH) indicates a loss of platelet function; increase is associated with an increased activation of platelets, for example, in patients with vascular diseases. Compared with other materials (e.g., collagen, glass pearls, etc.) the filter surface in the retention tubes is nonthrombogenic. Therefore, the RTH(More)
From the skeletal remains of about 5800 individuals from the charnel house of Eggenburg there were 2200 individuals of late medieval date. These were checked for injuries and pathologies. Of the skulls 410 showed various injuries and 430 pathologies. These pathologies could be differentiated into 20 groups. The frequencies of injuries (18.7%) and(More)
