A compreensão da base molecular da variação fenotípica observada dentro e entre espécies, como acontece na longevidade, é um dos principais objetivos da Biologia. Em Drosophila melanogaster foram já identificados mais de 50 genes que podem contribuir para a definição do tempo de vida. Contudo, na maioria dos estudos, as conclusões são baseadas em mutações criadas artificialmente noa genes alvo. Desta forma, é i...
The need to find solutions that would support the increasing number of users, has been stimulating many research groups to explore new techniques to increase the capacity of the mobile radio systems. This technique is nominated as SDMA. After a short introduction about GSM, this article presents a resume of some essential concepts to understand the study that was made. Then, some t...
Traumatic lung herniation is an unusual clinical problem. We present a case of a large left post-traumatic lung hernia on the left, anterior, second intercostal space following blunt chest trauma. An important factor in the etiology of these lesions is the relative lack of muscular support of the anterior part of the chest. This report describes the diagnosis and management of a post-traumatic lung hernia.
Steatite is a mineral which has been employed in the carving of elements in facades of Brazilian historical buildings and churches since the 17th century. Over the years, many of those historical buildings suffered the consequences of weathering with a current need for restoration. Recently a special cement-based mortar containing additions of fine powder waste from mineral extraction of steatite has been devel...
The existence of an important disequilibrium between the two faces economic and political of the process of European integration is the departing point of this thesis. By associating such disequilibrium with the major present deficits in the EU of competitiveness, growth and employment; of political weight; of participation and democratic legitimacy; of capacity for decision and action and the present m...
Screening sorológico e avaliação de fatores de risco para a transmissão de Toxoplasma gondii foi conduzido em 2.126 gestantes no sul do Brasil. Entre as gestantes avaliadas, 74,5% (n=1.583) mostraram anticorpos específicos contra Toxoplasma gondii. O contato com o solo foi o maior fator associado à infecção. ; Serological screening and evaluation of exposure factors for Toxoplasma gondii transmission were co...
OBJETIVO: Discutir o que vem sendo descrito na literatura até então a respeito do tempo de consolidação das fraturas na picnodisostose. MÉTODOS: Treze novos casos foram estudados por questão de disponibilidade de prontuários e exames radiográficos, totalizando 44 fraturas englobando pacientes avaliados no período de novembro de 1970 a agosto de 2004, no Hospital Ortopédico de Goiânia. Pesquisa em campo, acompan...
This study evaluated the dimensional alterations and the solubility of two experimental endodontic sealers based on Copaifera multijuga oil-resin (Biosealer) and castor oil bean cement (Poliquil), maintained in different storage solutions. Twenty specimens (3 mm diameter and 2 mm height) of each sealer were assigned to 2 groups (n=10) according to the storage solution: simulated tissue fluid (STF) or distilled ...
Protein Structure Prediction (PSP) is a computationally complex problem. To overcome this drawback, simplified models of protein structures, such as the HP Model, together with Evolutionary Algorithms (EAs) have been investigated in order to find appropriate solutions for PSP. EAs with the HP Model have shown interesting results, however, they do not adequately evaluate potential solutions by using only the usu...
Várias doenças infecciosas e parasitárias foram descritas como possíveis causadoras de prejuízos cognitivos, destacando-se as neuroinfecções que, pela localização no SNC, podem evolver para quadros demenciais francos (embora passíveis de reversão). As vastas possibilidades etiológicas tem como resultado grande heterogeneidade de sintomas neuropsiquiátricos, o que pode dificultar a avaliação clínica, mas se util...
