For detailed reconstructions of atmospheric metal deposition using peat cores from bogs, a comprehensive protocol for working with peat cores is proposed. The first step is to locate and determine suitable sampling sites in accordance with the principal goal of the study, the period of time of interest and the precision required. Using the state of the art(More)
Concentrations of 3alpha-reduced neuroactive steroids are altered in depression and normalize after antidepressant pharmacotherapy with selective serotonin re-uptake inhibitors (SSRIs). We investigated the impact of mirtazapine on the activity of a key neurosteroidogenic enzyme, the 3alpha-hydroxysteroid dehydrogenase (3alpha-HSD), and on the levels of(More)
A case of nonsecretory multiple myeloma is presented. Radiological findings and bone marrow examination provided the diagnosis. Bone scintigraphy showed metastatic pulmonary calcification, thus demonstrating the potential superiority to any other routine diagnostic modality in detection of visceral calcification.
Sphagnum moss was collected from 21 ombrotrophic (rain-fed) peat bogs surrounding open pit mines and upgrading facilities of Athabasca bituminous sands in Alberta (AB). In comparison to contemporary Sphagnum moss from four bogs in rural locations of southern Germany (DE), the AB mosses yielded lower concentrations of Ag, Cd, Ni, Pb, Sb, and Tl, similar(More)
In 110 patients with signs of cerebral infarct computed tomography (CT) and intravenous digital subtraction angiography (DSA) were performed. With DSA 63 arterial wall lesions could be seen, in CT 27 infarcts were found. In 9 examinations DSA was not diagnostic. Combination of both methods makes it possible to relate vascular lesions with size and(More)
Titanium concentrations and Ti inventories (total Ti in the sample) in living Sphagnum mosses from the surfaces of eight ombrotrophic peat bogs of five different regions of Germany and Belgium were studied over a period of two years (1995-7). Six to ten peat moss samples with a given surface area (100 cm2) and length (5 cm) were collected at different sites(More)
Intravenous digital subtraction angiography (DSA) and 131J-hippuran clearance (NSS) were evaluated in 113 patients, both methods were made as screening tests for renovascular hypertension. In 9 examinations DSA was not diagnostic, in 18 patients arterial wall lesions were found. The dynamic renal imaging with hippuran showed alterations in 86 patients, 2(More)
