The interior of motor vehicles is made of a wide variety of synthetic materials, which emit volatile organic compounds (VOC). We tested the health effects of emissions from vehicles exposed to "parked in sunshine" conditions. A new and a 3 year old vehicle with identical interior were exposed to 14 000 W of light. Indoor air was analyzed by GC-MS. Toxicity(More)
The substructural organization of completely crystalline peroxisomes present in Hansenula polymorpha cells grown under methanol limitation in a chemostat was investigated by different cytochemical and ultrastructural techniques. Time-dependent cytochemical staining experiments indicated that activities of the two main constituents of these organelles,(More)
PURPOSE To prospectively evaluate the safety and effectiveness of magnetic resonance (MR) imaging-guided galvanotherapy in prostate cancer. MATERIALS AND METHODS This prospective study was approved and authorized by the institutional review board, and patients gave informed consent. Forty-four men (mean age, 63.1 years) with histologically proved prostate(More)
To investigate whether regional calcification patterns at CT coronary artery calcium scoring (CCS) correlate with stenosis and non-calcified plaque formation. We studied 106 patients with quantitative catheter angiography (QCA), CCS, and coronary CT angiography (cCTA). CCS was determined globally and for each artery separately. The morphological pattern of(More)
The purpose of this study was to examine the feasibility and safety of MR-guided biopsies with a newly designed cordless coil in an open low-field magnetic resonance (MR) system. Eleven patients were biopsied using a low-field system (0.2 T, Magnetom Concerto, Siemens) by using the new cordless coil (Siemens). The biopsies were performed in different organ(More)
Present state of the art does not allow guaranteeing the exemption of unwanted biological growth on building coatings under all circumstances without the use of biocides. Currently only a limited range of active substances against façade microorganisms are available. In order to achieve an appropriate and ecological use of biocides in building coatings it(More)
During flights, reduced odor and taste perception is reported. Passengers tend to prefer spicier meals than on the ground. The conditions on board were simulated at the Fraunhofer flight test facility in Holzkirchen, Germany, consisting of a front fuselage of an Airbus A310-200 in a huge metal tube in which all relevant parameters can be adjusted (humidity,(More)
Methane is not only a potent greenhouse gas but also a modern biofuel, which is produced mainly by biological methanation in biogas plants. Here we describe an alternative process of methane production, called „microbial electrosynthesis“. This process has the potential to reduce CO2 emissions and to convert electrical excess current or renewable energies(More)
In nature, different bacteria have evolved strategies to transfer electrons far beyond the cell surface. This electron transfer enables the use of these bacteria in bioelectrochemical systems (BES), such as microbial fuel cells (MFCs) and microbial electrosynthesis (MES). The main feature of electroactive bacteria (EAB) in these applications is the ability(More)
Noncardiac findings occur in 10% to 60% of cases depending on the patient population studied. Although most of the abnormalities will turn out to be benign, important findings such as pulmonary embolism and lung cancer occur. Not all important abnormalities will occur within the coned down field-of-view for evaluating the coronary arteries, and the entire(More)
