Haloacetic acids (HAAs) are produced by the reaction of chlorine with natural organic matter and are regulated disinfection by-products of health concern. Biofilms in drinking water distribution systems and in filter beds have been associated with the removal of some HAAs, however the removal of all six routinely monitored species (HAA(6)) has not been previously reported. In this study, bench-...

OBJECTIVE To quantitatively examine the effects of skin rejuvenation regimens in treating photodamaged skin. METHODS Fourteen patients with photodamaged skin were considered for analysis.

The means by which coxsackievirus type A9 (CA9) is inactivated by proteolytic enzymes was investigated. After reaction of (14)C-leucine-labeled CA9 with Pronase, free leucine was liberated as measured by radiochromatography. Treatment of (14)C-leucine-labeled CA9 with trypsin or proteolytic filtrates of Pseudomonas aeruginosa caused the release of a variety of labeled substances. The extent of ...

CONTEXT We have shown previously that trichloroacetic acid precipitation is an effective method of protein extraction from pancreatic fluid for downstream biomarker discovery, compared to other common extraction methods tested. OBJECTIVE We aim to assess the utility of ultracentrifugation as an alternative method of protein extraction from pancreatic fluid. DESIGN Proteins extracted from tr...
