Microcosm studies unveil relevant information in ecotoxicology. However, statistical evaluation of data gained from the different parts of the ecosystem often remain on unsatisfying, discretely level, e.g. separately for different species communities. A combination of different multivariate statistical methods enables an ecological interpretation of the found changes in zoo- and ...

Acute renal failure (ARF) complicates the clinical course of many critically ill patients and significantly adds to their morbidity and mortality. Efforts to develop techniques to prevent ARF or to facilitate its resolution largely have been unsuccessful. Aggressive hydration, minimizing nephrotoxins, and maintenance of "adequate" mean arterial pressure remain the ...

This paper highlights the not-so-obvious but compelling reasons why the same supportive audiences that can help performers attain their highest potential also may increase performers' risk of choking under pressure. Drawing primarily from social psychology research and theory, we conclude that audience support magnifies performance pressure and induces performers to ...

The etiology of neuropathic diabetic foot wounds can be summarized by the following formula: pressure x cycles of repetitive stress = ulceration. The final pathway to ulceration consists of an inflammatory response, leading to tissue breakdown. Mitigation of this response might reduce the risk of ulceration. This proof-of-concept trial evaluates ...

Species with restricted gene flow often show trait-shifts from one type of environment to another. In those rock-dwelling marine gastropods that lack larval dispersal, size generally decreases in wave-exposed habitats reducing risk of dislodgement, while increases in less exposed habitats to resist crab-crushing. In Littorina fabalis, however, snails of moderately ...
