Xanthine oxidoreductase (XOR) activity has been previously noted to be responsive to changes in O2 tension. While prior studies have focused on the extremes (0-3% and 95-100%) of O2 tensions, we report the influence of 10% O2 on endothelial cell XOR, a concentration resembling modest arterial hypoxia commonly found in patients with chronic cardiopulmonary(More)
The effect of an external supply of carbon dioxide and pH on the production of succinic acid by Anaerobiospirillum succiniciproducens was studied. In a rich medium containing yeast extract and peptone, when the external carbon dioxide supply was provided by a 1.5M Na2CO3 solution that also was used to maintain the pH at 6.0, no additional carbon dioxide(More)
Pravastatin and lovastatin, two HMG-CoA reductase inhibitors with similar cholesterol-lowering effects, differ in their lipid solubility. The hydrophilic characteristics of pravastatin may explain why the drug has not been detected in cerebrospinal fluid. On the other hand, lovastatin, a lipophilic compound, has been detected in the cerebrospinal fluid.(More)
As impacted permanent maxillary cuspids occur in 1-2% of the population, the general dentist should know the signs and symptoms of this condition and the interceptive treatment. Features of buccal or palatal cuspid impaction include lack of canine bulges in the buccal sulcus indicating a lingual eruption path and possible impaction; lack of symmetry between(More)
Implant restorations have become a primary treatment option for the replacement of congenitally missing lateral incisors. The central incisor and canine often erupt in less than optimal positions adjacent to the edentulous lateral incisor space, and therefore preprosthetic orthodontic treatment is frequently required. Derotation of the central incisor and(More)
OBJECTIVES Motivational interviewing (MI) is a research-supported, patient-centered counseling technique to support health behavior change. We evaluated training to help teachers use MI for oral health promotion in a multi-site, diverse, urban Head Start organization. METHODS MI training was evaluated based on the intervention's reach, effectiveness,(More)
