Powered Toothbrushes: An Opportunity for Biofilm and Gingival Inflammation Control.

The present review aimed at a broad investigation on the potential of powered as compared to manual toothbrushes in different aspects of clinical dentistry. Studies evaluating plaque and gingival inflammatory parameters were included, as well as those that investigated adverse effects. Emphasis was given separately to adults, youngsters, special-needs patients, and those under fixed orthodontic therapy.

Re-examining the spectra of macromolecules. Current practice of spectral quasi B-factor flattening.

The analysis of structure factors in 3D cryo-EM Coulomb potential maps and their "enhancement" at the end of the reconstruction process is a well-established practice, normally referred to as sharpening. The aim is to increase contrast and, in this way, to help tracing the atomic model. The most common way to accomplish this enhancement is by means of the so-called B-factor correction, which applies a global filter to boost high frequencies with some dampening considerations related to noise amplification.

"It Was a Different Environment": Evaluating a Cultural Exchange Program.

Background: As nursing colleges seek to respond to the demands of the profession for nurses who are globally engaged and of the students for global health educational experiences, Riner's Globally Engaged Nursing Education framework is an effective tool for developing and evaluating an experience.

Method: Using Riner's framework, faculty and students at a nursing college evaluate an inaugural cultural exchange program between their U.S.
