Psychological detachment from work refers to the off-job experience of "switching off" mentally. It is hypothesized that a high degree of workload encountered during the work day has a negative impact on subsequent detachment processes and that psychological detachment from work is positively related to well-being. Eighty-seven individuals from various(More)
The treatment of mice with repeated injections of BUdR and FUdR allows for the demonstration of differentially stained metaphases from bone marrow after FPG (fluorescence plus Giemsa; Perry and Wolff, 1974) treatment. Thus, it is possible to determine the number of SCE's under in vivo conditions, which appears as a very promising system for mutagenicity(More)
The reaction of the rice mutant HEBIBA differs from that of wild-type rice in that the mutant responds inversely to red light and is defective in the light-triggered biosynthesis of jasmonic acid (JA). Using the wild type and the HEBIBA mutant of rice in a differential display screen, we attempted to identify genes that act in or near the convergence point(More)
N-Nitrosodiethylamine (DEN) and N-isopropyl-alpha-(2-methylhyadrazino)-p-toluamide (Natulan) were examined with the in vivo SCE method of Vogel and Bauknecht. Only Natulan showed a positive effect with a significant increase of induced SCE between 10 and 25 mg/kg b.w. The six-point curve of the dose effect was of the plateau type. With DEN only a slight(More)
The induction of mitotic gene conversion of the nitrofuran derivatives nitrofurantoin (N-(5-nitro-2-furfuryliden)-1-aminohydantoin), nifurprazinum (1-(5-nitro-2-furyl)-2-(6-amino-3-pyridazyl)-ethylenehydrochloride) and FANFT (2-formylamino-4-(5-nitro-2-furyl)thiazole) was investigated in the D4-RDII strain of Saccharomyces cerevisiae (heteroallelic at the(More)
A 4 month prospective study was performed to assess the incidence and routes of endogenous or exogenous colonization and nosocomial infection caused byStaphylococcus aureus andPseudomonas aeruginosa in surgical critically ill patients. A total of 4634 specimens ware obtained. Patient's nasal, scalp, and rectal swabs as well as tracheal secretion (TS) were(More)
Pretreatment of Chinese hamsters with phorone (diisopropylidene acetone) decreased hepatic glutathione (GSH) content to about 20% of the control level after 2 hours. The GSH S-transferase activities were not affected. As a consequence of reduced detoxication by GSH the potency of 3,4-benzo(a)pyrene to induce sister chromatid exchanges in vivo in bone marrow(More)
Diabetic mastopathy is a recently described collection of radiographical and histological features found in dense fibrous masses of the breast in long standing Type I diabetes. We describe the first case of bilateral disease with the alternate progression and regression of the disease over a 5 year period. A 45-year-old woman has been affected of insulin(More)
1 Most hair dyes contain the structural isomers ortho-, meta- and para- aminophenol which were investigated concerning their ability to induce sister chromatid exchanges (SCE) in cultured human lymphocytes in vitro and in Chinese hamster bone marrow cells in vivo. 2 In vitro only ortho-aminophenol significantly induced SCE in a dose-dependent manner. 3 In(More)
