A significant problem with most field dental units is that their suction is too weak to effectively remove debris from the mouth. The purpose of this study was to determine the minimum clinically acceptable suction level for routine dentistry. A vacuum pump was connected to a high-volume dental evacuation line in a simulated clinical setting and different suction airflow rates were evaluated by...

Unlike other nutrients, such as protein and calcium, where requirements are provided in grams per cow per day for specific body weight and milk production levels, fiber “requirements” are merely minimum guidelines (NRC, 2001) aimed at maintaining normal ruminal pH, fiber digestion and milk fat test and preventing sub-acute rumen acidosis (SARA), laminitis and displaced abomasums (LDA). NRC (200...

The aims of this work were as follows: 1) to determine whether a purified diet currently used for studies with rats was acceptable for reproductive studies in frogs; and 2) to determine whether frogs are sensitive to a deficit of boron (B) in the diet. Adult Xenopus laevis were fed a nonpurified beef liver and lung (BLL) diet (310 microg B/kg), a purified diet supplemented with boron (+B; 1850 ...

BACKGROUND Limited data are available on the effects of a ketogenic diet on dispersion duration of P-wave and QT-interval measures in children. We searched for the changes in these measures with serial electrocardiograms in patients treated with a ketogenic diet. METHODS Twenty-five drug-resistant patients with epilepsy treated with a ketogenic diet were enrolled in this study. Electrocardiog...

Dietary changes needed to achieve nutritional adequacy for 33 nutrients were determined for 1719 adults from a representative French national dietary survey. For each individual, an iso-energy nutritionally adequate diet was generated using diet modeling, staying as close as possible to the observed diet. The French food composition table was completed with free sugar (FS) content. Results were...

The chemical policies of the 1970s were limited by the assumptions that lie at their foundation and focused narrowly on only the most hazardous chemicals. The effective management of chemicals requires policies that focus on the entire body of chemicals and the production systems that make them. The future will require comprehensive chemicals policies that work within a systems framework to pha...

Water obtained from a hydrogen-oxygen fuel cell was subjected to chemical, organoleptic, and microbiological analyses and found to be acceptable according to the U. S. Public Health Service Standards. To ascertain the acceptability of this water, eight male subjects were confined to a self-care unit at Miami Valley Hospital, Dayton, Ohio, for a 2-week period and served a controlled 4-meal-perda...
