    Specificity of androgen resistance inMus caroli kidney (1988)

    Notes: Abstract Androgen controls the expression of β-glucuronidase and several other proteins in the kidney of the standard laboratory mouse,Mus musculus. Other species within the genusMus exhibit a variety of response patterns for kidney β-glucuronidase and other markers of androgen action. We have investigated the mechanism of androgen action inM. caroli, aMus species that does not produce β-glucuronidase in response to testosterone. The failure of testosterone to induce β-glucuronidase inM. caroli females cannot be overcome by treatment with dihydrotestosterone, with pharmacological doses of testosterone propionate or dihydrotestosterone propionate, or with a variety of potent androgen analogues. All of these compounds induce kidney β-glucuronidase inM. musculus females and kidney ornithine decarboxylase, submandibular gland renin, and submandibular gland epidermal growth factor in bothM. caroli andM. musculus females. Furthermore, kidney androgen receptor proteins fromM. caroli andM. musculus animals have the same sedimentation characteristics on sucrose density gradients. These data indicate that androgen resistance inM. caroli is not due to deficient 5α-reductase or aberrant hormone metabolism producing suboptimal levels of functional androgen and is not caused by a defective androgen receptor. They suggest that the resistance of β-glucuronidase inM. caroli kidney to induction by androgen occurs at the level of the β-glucuronidase gene.

    Beta decay of22O (1989)

    Notes: Abstract The beta-gamma spectroscopic study of22O is presented. This nucleus, produced as a projectile-like fragment from the interaction of a 60 MeV/n40Ar beam with a Be target, has been separated by the LISE spectrometer. Several gamma rays from22O decay have been observed, from which a half-life of (2.25±0.15)s has been determined. Accurate excitation energies have been deduced for several states in22F. A partial beta decay scheme of22O has been established. Experimental results have been compared with shell model calculations.

    Short-term effects of a catastrophic beaver dam collapse on a stream fish community (1991)

    Notes: Synopsis We examined the short-term effects of the natural catastrophic collapse of a beaver dam on downstream benthic insect density and fish community structure in a headwater tributary of the Mississippi River. The catastrophic collapse of the dam and ensuing flash flood resulted in a dramatic (〈 90%) decrease in benthic insect density in riffle and pool habitats. Sixty days after collapse of the dam, insect densities in riffles were 62% of pre-collapse densities. Insect recolonization of pools was slower than for riffles; 60 days after collapse of the dam insect densities in pools were 8% of pre-collapse levels. Collapse of the beaver dam altered the structure of the downstream fish community by causing a short-term (2–4 days) influx of pond species, resulting in a brief increase in species richness and abundance. Fish species richness and abundance then decreased for 4–60 days to levels below those prior to the collapse.
