OBJECTIVES The purpose was to study the effects on the nervous system in welders exposed to aluminium and manganese. METHODS The investigation included questionnaires on symptoms, psychological methods (simple reaction time, finger tapping speed and endurance, digit span, vocabulary, tracking, symbol digit, cylinders, olfactory threshold, Luria-Nebraska(More)
Surface layers (S-layers) comprise the outermost cell envelope component of most archaea and many bacteria. Here we present the structure of the bacterial S-layer protein SbsC from Geobacillus stearothermophilus, showing a very elongated and flexible molecule, with strong and specific binding to the secondary cell wall polymer (SCWP). The crystal structure(More)
A promising new approach for the production of biocatalysts comprises the use of surface-layer (S-layer) lattices that present functional multimeric enzymes on their surface, thereby guaranteeing most accurate spatial distribution and orientation, as well as maximal effectiveness and stability of these enzymes. For proof of concept, a tetrameric and a(More)
Tension of the forehead increases as a response to unpleasant stimuli. In three experiments EMG activity in corrugator muscle was measured to test this response as an indicator of noise annoyance. In Exp. 1 (n = 24) monotonic sound level-response functions were obtained for four levels of 100- and 1000-Hz tones. In Exp. 2 (n = 20) recordings were made(More)
The Gram-positive bacterium Geobacillus stearothermophilus ATCC 12980 is completely covered with a two-dimensional crystalline monolayer composed of the S-layer protein SbsC. In order to complete the structure of the full-length protein, additional soluble constructs containing the crucial domains for self-assembly have been successfully cloned, expressed(More)
Heart rate, performance, and symptoms were studied in six female and six male volunteers, aged 19 to 47 years, during experimental 2-hr exposures to 10 and to 200 mg/m3 of methyl isobutyl ketone (MIBK). No effects from exposure on performance of a reaction time task or an arithmetic test could be demonstrated, and no consistent effects on heart rate were(More)
The S-layer protein SbsC from Geobacillus stearothermophilus ATCC 12980 is the most prevalent single protein produced by the bacterium and covers the complete bacterial surface in the form of a two-dimensional crystalline monolayer. In order to elucidate the structural features of the assembly domains, several N-terminally truncated fragments of SbsC have(More)
BACKGROUND Periostin (osteoblast-specific factor OSF-2) is a secreted protein occurring in seven known isoforms, and it is involved in a variety of biological processes in osteology, tissue repair, oncology, cardiovascular and respiratory systems or allergic manifestations. To analyze functional aspects of periostin, or the ability of periostin as potential(More)
