LED photobiomodulation therapy combined with biomaterial as a scaffold promotes better bone quality in the dental alveolus in an experimental extraction model.

A bone scaffold added to the dental alveolus immediately after an extraction avoids bone atrophy and deformity at the tooth loss site, enabling rehabilitation with implants. Photobiomodulation accelerates bone healing by stimulating blood flow, activating osteoblasts, diminishing osteoclastic activity, and improving the integration of the biomaterial with the bone tissue. The aim of the present study was to evaluate the effect of photobiomodulation with LED at a wavelength of 850 nm on bone quality in Wistar rats submitted to molar extraction with and without a bone graft using hydroxyapatite biomaterial (Straumann® Cerabone®).

Genotoxicity and mutagenicity research in Quilombola communities.

The Quilombola communities are mostly isolated and deprived of sources of treated water, garbage collection and sewage, consuming fresh water from wells, streams, lakes, among others. This lack of basic infrastructure can be a relevant factor in exposing residents to substances and factors that are harmful to the integrity of their genetic material that can lead to carcinogenesis. Based on this, the objective of this study was to evaluate the genomic and mutagenic/cytotoxic damage in the adult population of two Quilombola communities (one urban and another rural region), in the state of Goiás, Brazil.

Feasibility of ramie fibers as raw material for the isolation of nanofibrillated cellulose.

In this study, a strategy was adopted to enhance the use of ramie fibers as raw material for isolation of cellulose nanofibers (CNFs). Ramie pulp was produced by alkaline organosolv followed by bleaching. CNFs were produced by mechanical defibrillation, and films were fabricated via casting.

The Reliability of the Brief Visuospatial Memory Test - Revised in Brazilian multiple sclerosis patients.

Unlabelled: Cognitive Impairment (CI) is a common and distressing problem in Multiple Sclerosis (MS). Its identification is complicated and sometimes omitted in the routine evaluation by neurologists. The BICAMS (Brief International Cognitive Assessment for Multiple Sclerosis) is a promising tool to overcome this difficulty.

Evaluation of the satisfaction of users of a service specialized in diabetes mellitus.

Objective: to evaluate the satisfaction of users of a service that specializes in diabetes mellitus.

Method: evaluative research, with mixed approach, developed at the Integrated Center for Diabetes and Hypertension of Barbalha-CE, in the period from 2011 to 2014, with 97 users. Data concerning the characterization and satisfaction of users in relation to the dimensions of infrastructure, accessibility and the user-health team relationship were collected.
