Legacy organochlorine pollutants in glacial watersheds: a review.

Northern Hemisphere alpine glaciers have been identified as a point of concentration and reemergence of legacy organochlorine pollutants (OCPs). In this review, we compile a selection of published literature combining long-range, global atmospheric transport and distribution-based compartmental environmental flux models, as well as data from glacial meltwater, ice core, crevasse and proglacial lake sediment studies. Regional studies of ice and meltwater in alpine glaciers of the northern latitudes show similarities in sample deposition profiles and concentration due to chemical atmospheric residence time, precipitation type and glacier flow rates.

Depression as a Clinical Determinant of Dependence and Low Quality of Life in Elderly Patients with Cardiovascular Disease.

Background: The aging process promotes a progressive increase in chronic-degenerative diseases. The effect of these diseases on the functional capacity has been well recognized. Another health parameter concerns "quality of life related to health".

Glycoside hydrolase production by an anaerobic rumen fungus Caecomyces communis.

The ruminal fungus Caecomyces communis was grown anaerobically either in a discontinuous cultivation system or in a fermentor with daily withdrawal and addition of fresh medium. Lowe and Orpin media were tested. The best culture conditions for glycoside hydrolase production were obtained in Lowe medium with daily fresh medium addition, whereas the Orpin medium with ruminal fluid was favourable to fungal growth and to the enzyme export process.

Polysaccharide hydrolase production by the rumen fungus Caecomyces communis.

The anaerobic fungus Caecomyces communis was grown in a fermentor in either a discontinuous cultivation system or in a culture system with daily withdrawal and addition of fresh medium. Lowe and Orpin media were tested. The Lowe medium was best for the stimulation of enzyme production, the Orpin medium, for the stimulation of fungal growth and enzyme release.

Glycoside and polysaccharide hydrolase activity of the rumen anaerobic fungus Caecomyces communis (Sphaeromonas communis SENSU ORPIN) at early and final stages of the developmental cycle.

The rumen anaerobic fungus Caecomyces communis was grown in a fermentor in Lowe medium. We studied four polysaccharide hydrolases and three glycoside hydrolases at early and final stages. We found a difference in cell association for these enzymes depending on the developmental stage.
