Antimicrobial photodynamic action on dentin using a light-emitting diode light source
(Mary Ann Liebert, Inc., 2008-08-01)
Objective: The aim of this study was the evaluation of two different photosensitizers activated by red light emitted by light-emitting diodes (LEDs) in the decontamination of carious bovine dentin.Materials and Methods: ...
Prenatal ethanol exposure increases ethanol intake and reduces C-fos expression in infralimbic cortex of adolescent rats
(Elsevier Inc, 2012-12)
Prenatal ethanol exposure significantly increases later predisposition for alcohol intake, but the mechanisms associated with this phenomenon remain hypothetical. This study analyzed (Experiment 1) ethanol intake in ...
Chronic exposure to fine particulate matter emitted by traffic affects reproductive and fetal outcomes in mice
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Air pollution is an important environmental health risk factor that can result in many different gestational and reproductive negative outcomes. In this study, we have investigated the effects of two different times of ...

Metabolism of Odontoblast-like cells submitted to transdentinal irradiation with blue and red LED
(Elsevier B.V., 2017-11-01)
Objectives: The present study evaluated the trans-dentinal effect of light emitting diodes (LEDs) irradiation on the metabolism of odontoblast-like cells. Methods: Seventy-two dentin discs (0.2 mm thick) were obtained from ...
Investigation of exposure to occupational noise among forestry machine operators: A case study in Brazil
(2021-03-01)
In mechanized harvesting of wood operations, in a cut-to-length system, occupational noise is emitted by self-propelled forest machines, which compromises the safety and health of operators. Therefore, the occupational ...
