1. Simulation of Stress Distribution on the Upper First Molar and Alveolar Bone with the Transpalatal Arch and Upper Second Molar Using Finite Element Analysis
Abstract Objective: To evaluate the differences in the stress distribution on the upper first molar with and without transpalatal arch and a second molar when a 150 g force is applied during canine distalization using finite element analysis. Material and Methods: We constructed several models with data obtained by scanning human skulls using cone beam com

2. Correlation Between Palatal Depth and Duration of Upper Airway Obstruction Since Diagnosis in Children
Abstract Objective: To analyze the correlation between palatal depth and duration of the upper airway obstruction since diagnosis among children with habitual mouth breathing. Material and Methods: This cross-sectional analytical study was conducted using the consecutive sampling method on boys and girls who were habitual mouth breathers and presented with

3. Effects of growth hormone in the central nervous system
ABSTRACT Growth hormone (GH) is best known for its effect stimulating tissue and somatic growth through the regulation of cell division, regeneration and proliferation. However, GH-responsive neurons are spread over the entire central nervous system, suggesting that they have important roles in the brain. The objective of the present review is to summarize a

4. Insulin signaling in the whole spectrum of GH deficiency
ABSTRACT GH is one of the insulin counterregulatory hormones which acts in the opposite way to insulin, increasing the glucose production by the liver and kidneys and decreasing glucose uptake from peripheral tissues, thus being a hyperglycemic hormone. When in excess, as in acromegaly, it induces glucose intolerance and diabetes. As expected, patients with

5. Digital models: How can dental arch form be verified chairside?
RESUMO Introdução: os modelos de gesso são usados rotineiramente, durante a prática clínica, para avaliação da forma da arcada inferior e para auxiliar na confecção de arcos ortodônticos individualizados. A tecnologia dos modelos digitais, introduzida recentemente, pode oferecer uma limitação na obtenção de um registro físico da arcada dent�

6. 3D analysis of effects of primary surgeries in cleft lip/palate children during the first two years of life
Abstract This study aimed at monitoring the maxillary growth of children with cleft lip/palate in the first two years of life, and to evaluate the effects of primary surgeries on dental arch dimensions. The sample consisted of the three-dimensional digital models of 25 subjects with unilateral complete cleft lip and palate (UCLP) and 29 subjects with isolate

7. Using ecological niche models to predict the impact of global climate change on the geographical distribution and productivity of Euterpe oleracea Mart. (Arecaceae) in the Amazon
ABSTRACT We assess the impact of climate change on the geographic distribution and productivity of Euterpe oleracea (Arecaceae), commonly called açaí. To construct the ecological niche model of E. oleracea, we used 95 points of occurrence, five bioclimatic variables in current and future climate scenarios and Maxent software. The Akaike Information Criteri

8. Melatonin prevents hyperglycemia in a model of sleep apnea
Objective Obstructive sleep apnea is a common disorder associated with aging and obesity. Apneas cause repeated arousals, intermittent hypoxia, and oxidative stress. Changes in glucolipidic profile occur in apnea patients, independently of obesity. Animal models of sleep apnea induce hyperglycemia. This study aims to evaluate the effect of the antioxidants

9. Reliability of measurements on virtual models obtained from scanning of impressions and conventional plaster models
Aim: To evaluate the reliability of linear measurements in virtual models by comparing measurements performed on virtual models obtained from alginate impression scans, plaster model and measurements performed on conventional plaster model. Methods: The sample comprised 26 randomly selected patients to have impressions of their upper and lower jaws taken usi

10. Application of nonlocal elasticity and DQM to dynamic analysis of curved nanobeams
In this paper, a new numerical technique, the differential quadrature method (DQM) has been developed for dynamic analysis of the nanobeams in the polar coordinate system. DQ approximation of the required partial derivatives is given by a weighted linear sum of the function values at all grid points. A semicircular arch with small-scale effects is investigat

11. Evaluation of two methods for mixed dentition analysis using the method error
AIM: In order to determine the reliability between two of these methodologically different method, this study evaluated the systematic and random errors of the method proposed by Tanaka and Johnston, which is based on the sum of mandibular permanent incisors, and the Huckaba method, which uses radiographs. METHODS: In a random sample of 28 plaster mode

12. New volatility models under a Bayesian perspective: a case study
Neste artigo, apresentamos uma breve descrição dos modelos ARCH, GARCH e EGARCH. Normalmente, as estimativas dos parâmetros desses modelos são obtidos através de métodos de máxima verossimilhança. Considerando-se novos processos metodológicos para modelar as volatilidades das séries temporais, precisamos usar outra abordagem de inferência para obt
