The electroencephalogram (EEG) is a non-invasive and affordable technique to study the brain activity during wakefulness and especially during sleep. The current trend on sleep analysis focuses on its dynamic organization described in the cyclic alternating pattern (CAP) paradigm. This paradigm looks to the EEG microstructure, gives attention to the short(More)
INTRODUCTION Periodontal disease is a chronic inflammation of the attachment structures of the teeth, triggered by potentially hazardous microorganisms and the consequent immune-inflammatory responses. In humans, the T helper type 17 (Th17) lineage, characterized by interleukin-17 (IL-17) production, develops under transforming growth factor-beta(More)
BACKGROUND Extracellular matrix proteins are key factors that influence the regenerative capacity of tissues. The objective of the present study was to evaluate the effects of enamel matrix derivative (EMD), TGF-β1, and the combination of both factors (EMD+TGF-β1) on human osteoblastic cell cultures. METHODS Cells were obtained from alveolar bone of three(More)
The aim of this study was to evaluate the efficacy of electro-acupuncture (EAC) on postoperative pain control after mandibular third molar surgery. Twenty four young patients (12 male and 12 female) with symmetrically impacted mandibular third molars were selected. Each patient was submitted to two separate surgical procedures under local anesthesia. At one(More)
1. The effect of intracerebroventricular (i.c.v.) injection of bradykinin (BK) and related peptides was tested on the dental pulp electrical stimulation threshold (DPEST) in rats. 2. BK (4, 8 and 16 nmol) induced a dose-dependent increase of DPEST, indicative of an antinociceptive effect. 3. I.c.v. injection of equimolar doses of BK-related peptides, Lys-BK(More)
A current goal of dental implant research is the development of titanium (Ti) surfaces to improve osseointegration. Plasma nitriding treatments generate surfaces that favor osteoblast differentiation, a key event to the process of osteogenesis. Based on this, it is possible to hypothesize that plasma-nitrided Ti implants may positively impact(More)
This study evaluated the temporal expression of osteopontin (OPN) in co-cultures of human osteoblastic cells (SAOS-2) and oral squamous cell carcinoma (OSCC)-derived cells (SCC9) and examined the effects of osteoblast-derived OPN on the neoplastic cell phenotype. Additionally, the effects of these co-cultures on subsequent osteoclastic activity were(More)
OBJECTIVE We investigated the osteoblast and adipocyte differentiation of mesenchymal stem cells (MSCs) from young and aged rats cultured on Ti. MATERIAL AND METHODS Bone marrow MSCs derived from 1-month and 21-month rats were cultured on Ti discs under osteogenic conditions for periods of up to 21 days and osteoblast and adipocyte markers were evaluated.(More)
UNLABELLED The ability of hemostatic agents to promote bone repair has been investigated using in vitro and in vivo models but, up to now, the results are inconclusive. Objective In this context, the aim of this study was to compare the potential of bone repair of collagen sponge with fibrin glue in a rat calvarial defect model. MATERIAL AND METHODS(More)
