Abstrakt 1. Hinsichtlich der Frage der Anerkennung einer Heilmethode kommt es nicht darauf an, ob eine Methode von der überwiegenden
Mehrheit der sogenannten Schulmediziner anerkannt wird, aber auch nicht, ob die betreffende Methode „therapieimmanent“, also
von denjenigen, die diese Methode entwickelt haben oder sie anwenden, als wirksam eingesch?tzt wird. Entscheidend ist vielmehr
auf die Anerkennung derjenigen Personen abzustellen, die sich von dritter Seite als Wissenschaftler in einem wissenschaftlichen
Verfahren mit der Frage der Wirksamkeit der betreffenden Methode auseinandergesetzt haben.
2. Der Wirkmechanismus der Bioresonanztherapie ist nach strengen naturwissenschaftlichen Untersuchungen nicht zu erkl?ren.
Diese Methode ist jedoch von der Hufelandgesellschaft, die sich aus 25 ?rztegesellschaften zusammensetzt, die allesamt auch
Naturheilverfahren betreiben, anerkannt. (Leits?tze des Bearbeiters) 相似文献

Quadricuspid aortic valve is a rare congenital malformation of the aortic valve. Most cases are discovered incidentally at autopsy or at aortic valve replacement. Recent advances in echocardiography epecially transesophageal echocardiography led to diagnosis of more cases before surgery. Two cases of quadricuspid aortic valve are presented. 相似文献

Glucose-6-phosphate dehydrogenase variants: reexamination of G6PD Chicago and Cornell and a new variant (G6PD Pea Ridge) resembling G6PD Chicago 总被引:3,自引:0,他引:3
Two large and unrelated families were investigated for hereditary nonspherocytic hemolytic anemia associated with deficiency of erythrocyte glucose-6-phosphate dehydrogenase (G6PD). In both families, the kinetic and electrophoretic features of the G6PD variants resembled those of G6PD Chicago. Further investigation revealed that members of one of these families previously had been characterized as having the G6PD variants Chicago and Cornell. However, it is clear that each of these terms has been applied to the same variant in this single large kindred. In the second family, we describe a newly identified variant with unique characteristics, which we have designated G6PD Pea Ridge. G6PD Pea Ridge resembles G6PD Chicago but differs in electrophoretic mobility and in a few kinetic parameters. It exhibits an unusually high Ki for NADPH and thus appears to be insensitive to product inhibition. As other cases previously considered to be the Chicago variant become more fully characterized, this probably will be shown to be a heterogeneous group of variants. 相似文献

In this work, a pioneering study on the electrical properties of composite carbon nanofibres (CNFs) using current-sensitive atomic force microscopy (CS-AFM) has been demonstrated. CNFs are highly interesting materials which are usable in a wide array of applications e.g. electrode materials for biosensors, lithium ion batteries, fuel cells and supercapacitors. CNFs offer a high specific surface area and thus have a high contact area for charge transfer. CNFs can be produced using spinnable polyacrylonitrile (PAN) as a precursor for carbonisation. For the purpose of developing efficient CNFs with high conductivity and power density, silver nanoparticle (AgNPs)-containing PAN solutions were electrospun to form composite nanofibres which was followed by heat treatment. The applied voltage of the spinning setup and the content of both PAN and the silver nanoparticles in the spinning solution were varied in order to study their influence on the morphology and the electrical properties of the nanofibres. The resultant morphologies and fibre diameters were determined by scanning electron microscopy (SEM). The formation of silver nanoparticles was characterised in solution by UV-visible absorption spectroscopy and dynamic light scattering (DLS), while energy-dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM) were carried out to investigate the presence as well as the average diameter of the AgNPs. The electrical properties of the CNFs were investigated using CS-AFM. This technique gives us the possibility to explore the electrical properties of single fibers and hence derive relationships between the structural features and the electrical properties. Our results show that the composite CNFs have a higher electrical conductivity than the neat CNFs and both the average diameter of the fibers and the electrical conductivity increase with an increasing AgNP content.In this work, a pioneering study on the electrical properties of composite carbon nanofibres (CNFs) using current-sensitive atomic force microscopy (CS-AFM) has been demonstrated. 相似文献

Objectives The purpose of this study was to investigate coronary blood flow properties in patients with diffuse coronary artery ectasia (CAE) associated with exercise-induced myocardial ischemia.Methods Seventeen patients with diffuse CAE and without coexisting coronary artery stenosis were enrolled in the study (CAE group). CAE was defined as luminal dilatation 1.5 to 2 times that of the adjacent normal coronary artery segment or the diameter of the corresponding coronary artery of the control group when there was no normal segment. The age- and sex-matched control group (n = 20) comprised patients with normal epicardial coronary arteries. Coronary blood flow velocities were obtained invasively by use of Doppler scanning flow wire. Coronary flow reserve (CFR) was measured by administration of intracoronary papaverine as the hyperemic stimulus. Volumetric coronary blood flow was estimated by multiplying the velocity time integral of coronary blood flow with the cross-sectional area of the coronary artery and the heart rate.Results Fifteen patients with CAE, but none of the patients in the control group, had electrocardiographic signs of myocardial ischemia at peak exercise on ergometry. Baseline average peak velocities (APVs) of coronary blood flow were similar in the 2 groups. Peak hyperemic APVs of coronary blood flow were lower in the CAE group than in the control group (17.5 ± 7.4 cm/s vs 41.5 ± 12.6 cm/s, respectively, P < .001). Volumetric coronary blood flow was significantly higher in the CAE group than in the control group, both at rest and at hyperemia (146.3 ± 71.2 cm3/min vs 45.1 ± 16.1 cm3/min, respectively, P < .001, and 202 ± 87.3 cm3/min vs 104.1 ± 37.6 cm3/min, respectively, P < .003). The mean CFR of the CAE group was significantly reduced compared with that of the control group (1.51 ± 0.31 vs 2.67 ± 0.52, respectively, P < .001).Conclusions The CFR is significantly reduced in patients with diffuse CAE compared to a matched control group. Although volumetric coronary blood flow is significantly higher in CAE, microcirculatory dysfunction that is reflected as depressed CFR may be the underlying cause of exercise-induced myocardial ischemia.
