AB  - The grey short-tailed opossum, Monodelphis domestica, has been an established research animal for more than five decades, but relatively, little is known about its thermophysiology. Here we studied core body temperature (T b) and metabolic rate (MR) of female adult M. domestica housed in the laboratory at an ambient temperature (T a) of 26 °C. In expanding previous reports, the average recorded core T b of M. domestica was 34.3 °C. The T b of an individual M. domestica can drop below 30 °C (minimal T b: 28.6 °C) accompanied by a reduction in MR of up to 52 % even while having ad libitum access to food. These findings demonstrate for the first time the presence of spontaneous torpor in M. domestica. Metabolic suppression at relatively high T a and T b furthermore broadens our perspective on the use of torpor as a metabolic strategy not just restricted to cold climates.

AB  - Much of our understanding of physiology and metabolism is derived from investigating mouse mutants and transgenic mice, and open-access platforms for standardized mouse phenotyping such as the German Mouse Clinic (GMC) are currently viewed as one powerful tool for identifying novel gene-function relationships. Phenotyping or phenotypic screening involves the comparison of wild-type control mice with their mutant or transgenic littermates. In our study, we explored the extent to which standardized phenotyping will succeed in detecting biologically relevant phenotypic differences in mice generated and provided by different collaborators. We analyzed quantitative metabolic data (body mass, energy intake, and energy metabolized) collected at the GMC under the current workflow, and used them for statistical power considerations. Our results demonstrate that there is substantial variability in these parameters among lines of wild-type C57BL/6 (B6) mice from different sources. Given this variable background noise in mice that serve as controls, subtle phenotypes in mutant or transgenic littermates may be overlooked. Furthermore, a phenotype observed in one cohort of a mutant line may not be reproducible (to the same extent) in mice coming from a different environment or supplier. In the light of these constraints, we encourage researchers to incorporate information on intrastrain variability into future study planning, or to perform advanced hierarchical analyses. Both will ultimately improve the detectability of novel phenotypes by phenotypic screening.

AB  - In the near future, the use of 137Cs from global fallout (Cs) as a tracer for erosion studies will no longer be possible in areas with a substantial deposition of Chernobyl-derived 137Cs. Therefore, we have used 239+240Pu from global fallout (Pu) as a tracer as well as 137Cs in order to determine long-term soil redistribution rates for an agricultural field (inclination about 20%, area approx. 3 ha) in Scheyern, Bavaria. The mean erosion and deposition rates derived from Cs were -37 and +52 t·ha-1·year-1, respectively; those from Pu were -32 and +39 t·ha-1·year-1. We found no statistical difference between the means obtained by the two tracers. In contrast to Pu, however, the rates obtained by Cs were not accurate enough to assure the presence of a net soil redistribution. Modeling of soil translocation in the field by water and tillage erosion resulted in estimates which were in reasonable agreement with the rates derived from Pu.

AB  - It is evident that ionizing radiation at high doses is able to damage living organisms and may induce cancer and leukemia in man. At low doses, however, biopositive effects appear possible too, for which examples are given. The mechanism of such effects can be explained as a general stimulation of the natural immune system. In conclusion, radiation at low doses is thus not as dangerous as often assumed but is rather essential for life and the maintenance of health.

AB  - There are several approaches to evaluate the genetic effects of low doses of ionizing radiation in a human population. Based on experiments on mice using high doses, the genetic risk for humans has to be derived by extrapolation to low doses, assuming mouse and man respond in a similar way. Microdosimetric considerations indicate a linear relationship; studies on the molecular mechanism of radiation-induced mutagenesis lead to the conclusion that, in addition to a constitutive mutagenic process, an inducible compound exists which may cause linear-quadratic dose-effect curves. Linear extrapolation seems thus to be justified; however, the genetic risk of low doses may be slightly overestimated.

AB  - The estimation and limitation of lung cancer risk from inhaled 222Rn-daughters in mines and in the home is one of the most important problems in radiation protection. The results of epidemiological studies are summarized. The radiation-induced increase in the age-specific lung cancer rate can be interpreted in terms of a proportional hazard model. On the basis of this model, the relative fraction of total lung cancer frequency which might be initiated by the radon-daughter exposure in homes is estimated.

Strains 7 C, RH 10, and 14 g are characterized by the snapping type of cell division, 68.5 to 69.7% GC content, dl-diaminopimelic acid in the cell wall, content of metachromatic granules, weak utilization of sugars and inhibitory effect of citrate. The strains are placed to the group 1-genus Corynebacterium-of the classification of coryneform bacteria of Yamada and Komagata (1972) and the name Corynebacterium autotrophicum sp.nov. is proposed. Strains 11 X and RH 12 are characterized by the bending type of cell division, a GC content of 70.2 and 70.5%, ll-diaminopimelic acid in the cell wall, absence of metachromatic granules, utilization of several sugars and no changes in cell morphology by citrate. The strains have to be placed to group 6 of coryneform bacteria.
