Abstract
Coprinus cinereus, which was able to decolorize the anthraquinone dye Cibacron Blue 3G-A (CB) enzymatically, was used as a biocatalyst for the decolorization of synthetic solutions containing this reactive dye. Coprinus cinereus was immobilized in both calcium alginate and polyacrylamide gels, and wa...

Abstract
Maltose-binding protein (MBP) is one of the most popular fusion partners being used for producing recombinant proteins in bacterial cells. MBP allows one to use a simple capture affinity step on amylose-agarose columns, resulting in a protein that is often 70-90% pure. In addition to protein-isolati...

Abstract
Overall, 46 of 68 ASCs (67.6%; 95% confidence interval [CI], 55.9%-77.9%) had at least 1 lapse in infection control; 12 of 68 ASCs (17.6%; 95% CI, 9.9%-28.1%) had lapses identified in 3 or more of the 5 infection control categories. Common lapses included using single-dose medication vials for more...

Abstract
Compared with controls (no respirator), significant decreases in the breathing rate at both work rates (P < .05) and increases in tidal volume at the lower work rate (P < .01) were noted with respirator use. Approximately half the subjects had transcutaneous carbon dioxide levels above the upper lim...

Abstract
We modelled the financial and environmental costs of two commonly used anaesthetic plastic drug trays. We proposed that, compared with single-use trays, reusable trays are less expensive, consume less water and produce less carbon dioxide, and that routinely adding cotton and paper increases financi...

Abstract
In a remote field setting the SpiroPro pneumotachometer tube can be cleaned and reused 5-9 times before it becomes inaccurate per the ATS criteria. Rigorous rinsing in distilled water and repeated calibration checks, at various flows up to 12 L/s, are essential for precise and accurate spirometry wi...

Abstract
When reusing or disposing of contaminated granular waste materials there is a need to evaluate how the contaminants will interact on the pathway soil-groundwater and the effect this interaction will have on the surrounding environment. While column testing can provide a closer approximation to field...

We gain a greater understanding of the mechanisms involved in this process, we also begin to unveil its complexities. The delicate balancing act played out by the multitude of DNA interacting proteins can easily become unhinged. The implications of this may potentially lead to cell death or a diseas...

Abstract
For all sizes, new instruments were more resistant to failure then the used ones (P < .05). A reduction in lifespan was observed ranging from 18% (30/.06) to 51% (25/.02). CONCLUSION: The results showed that clinical use significantly reduced cyclic fatigue resistance of RaCe rotary instruments comp...
