Transcranial Doppler sonography (TCD) is a simple method to detect a right-to-left cardiac shunt, although standardized procedures do not exist. In this study 69 patients were tested according to… (More)
In a retrospective study, ultrasonic Doppler findings obtained with directional continuous wave equipment were evaluated in 51 patients in whom subsequently the diagnosis of an internal carotid… (More)
The distribution of interstellar dust grains (ISDG) observ ed in the Solar System depends on the nature of the interstellar medium-solar wind interaction. The charge of the grains couples them to the… (More)
Flow reversal could be shown, by means of a directional ultrasonic flow detector designed to record pulse curves of the ophthalmic artery, in 31 out of 37 cases of complete occlusion of the internal… (More)
Mutational loss of p53 tumor suppressor functions has been observed in a wide range of neoplasms and was associated with either enhanced or decreased chemosensitivity of affected tumors. The dual… (More)
In breast cancer, hormone dependency is inversely correlated with the number of surface epidermal-growth-factor (EGF) receptors on the tumor cells. In vitro, EGF stimulated only hormone-dependent… (More)
