A microarray targeting four sequenced strains in the Dehalococcoides (Dhc) genus was used to analyze gene expression in a robust long-term trichloroethene (TCE)degrading microbial community (designated ANAS) during feeding cycles that involve conditions of periodic substrate supply. The Dhc transcriptome was examined at three timepoints throughout a batch feeding cycle: T1 (27 h) when TCE, dich...

The Smith-Lemli-Opitz syndrome (SLOS) is a multiple malformation/mental retardation syndrome caused by a deficiency of the enzyme 7-dehydrocholesterol Delta(7)-reductase. This enzyme converts 7-dehydrocholesterol (7-DHC) to cholesterol in the last step in cholesterol biosynthesis. The pathology of this condition may result from two different factors: the deficiency of cholesterol itself and/or ...

Transepithelial movement of water and solute occurs both through the cell membrane as well as across the intercellular junctional complex (paracellular shunt pathways). Permeability of paracellular shunt pathways is increase by transmucosal osmotic gradients, and in certain epithelia these changes are associated with bullous-like deformations (blisters) of the zonula occludens and localization ...

This retrospective study aims to determine whether there is a difference in the additional consumption of alcohol between addicts treated with methadone or dihydrocodeine (DHC) and untreated addicts injecting heroin. 1685 patients admitted for opioid withdrawal between 1991 and 1997 were reviewed. Cross-reference tables and multiple logistic regression analyses were carried out. 28% of patients...

YenJung Lai, Doctor of Philosophy, 2010 Directed By: Associate Professor, Jennifer G. Becker, Department of Environmental Science and Technology The chlorinated solvents tetrachloroethene (PCE) and trichloroethene (TCE) are common groundwater contaminants. Reductive de...

The prevalence of malocclusion and the need for orthodontic treatment were studied in 421 Swiss army recruits in the year 1996. The results were compared with the findings in a similar study of 757 recruits, done in the year 1985. The malocclusion prevalence and the need for treatment were evaluated with the Dental Health Component (DHC) and the Aesthetic Component (AC) of the Index for Orthodo...

Heat load prediction in district heating and cooling (DHC) systems is one of the key technologies for economical and safe operations of DHC systems. The heat load prediction method using a three-layered neural network proposed by the authors has been used in an actual DHC plant on a trial basis. However, there exists a drawback that its prediction becomes less accurate in periods when the heat ...
