OBJECTIVES To compare the skeletal and the airway structures of the non-snoring individuals with simple snoring and patients with obstructive sleep apnea (OSA). METHODS The first group consisted of 20 simple snoring cases (mean age: 37.5±8.05 years; max: 50 years, min: 21 years), the second group consisted of 20 OSA cases (mean age: 40.0±8.28 years; max: 54 years, min: 27 years) and the third...

The aims were to compare the physico-chemical properties (zeta-potential, wettability, surface free energy) of stereolithography materials (STL) (Photopolymer, Accura) to dentine and to evaluate the potential of each material to develop Enterococcus faecalis biofilm on their respective surfaces. Eighteen samples of each test material (Photopolymer, Accura, dentine) were employed (total n = 54) ...

Experimentally, depriving the basal ganglia (BG) from their dopaminergic innervation, dramatically changes the behavior of all their circuits, neurons, and synapses in multiple ways. Dopamine afferents are received by all BG nuclei (Rommelfanger and Wichmann, 2010). In the absence of DA, BG generate enhanced pathological oscillatory patterns in the external segment of the striatum: globus palli...

BACKGROUND AND PURPOSE The signal information per voxels of magnetic resonance imaging (MRI) for vessel wall could reflect the pathologic features of atherosclerotic vessels. The aim of this study is to evaluate the usefulness of magnetic resonance voxel-based histogram (VBH) of atherosclerotic basilar artery in patients with isolated pontine infarctions (PIs). MATERIALS AND METHODS Wall and ...

AIM To investigate the effects of endodontic treatment, post placement and ceramic restoration type on the fracture resistance of premolars. METHODOLOGY One hundred and twenty teeth maxillary premolars were allocated to four groups (A-D; n = 30). In group A, mesio-occlusal-distal-inlays with a buccal and palatal wall of 2 mm (MOD), in group B partial onlays with palatal cusp coverage and in g...

Crotoxin has been detoxified with gamma radiation in order to improve crotalic antiserum production. Nevertheless, present knowledge of the biological characteristics of irradiated crotoxin is insufficient to propose it as an immunizing agent. Crotoxin is known to increase the emotional state of rats and to decrease their exploratory behavior (Moreira EG, Nascimento N, Rosa GJM, Rogero JR and V...

UNLABELLED Aging of the worldwide population is a concern of most governmental entities, spanning practically all areas of prevention and rehabilitation. Aging leads to physiological alterations that result in adverse social and financial effects. There is a trend to emphasize prevention, which is less expensive and socially more desirable than therapeutic intervention. PURPOSE To assess the ...
