13. GENETIC ASPECTS OF IDIOPATHIC ESCOLIOSIS - A LITERATURE REVIEW
RESUMO A escoliose idiopática (EI) é a forma mais comum de deformidade da coluna vertebral. Porém, a patogênese ainda permanece mal compreendida. Diversos estudos apresentam evidências que o componente genético no desenvolvimento da EI é determinante. Nesse sentido, um foco crescente foi colocado na identificação de genes, polimorfismos genéticos a

14. Cicatrização: uso de matriz de colágeno
Resumo A matriz de colágeno Ologen TM é um novo agente antifibrótico composto por uma matriz porosa de atelocolageno tipo I e glicosaminoglicanos reticulados, que pode ser utilizado como uma alternativa para a modulação da cicatrização nas cirurgias. Por ser altamente poroso e biodegradável, este implante auxilia nos processos de reparação fisioló

15. Quantificação do colágeno dérmico equino por duas técnicas morfométricas: contagem de pontos e segmentação de cor
RESUMO Os colágenos tipos I e III apresentam diferentes tonalidades de birrefringência em cortes histológicos corados com Picrosirius red e analisados em microscópio sob luz polarizada. Com base nessa propriedade, os colágenos podem ser quantificados por histomorfometria. Entretanto, são muitas as variáveis que podem afetar a distribuição das cores

18. Purification and enzymatic characterization of a novel metalloprotease from Lachesis muta rhombeata snake venom
Abstract Background: Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2. Metalloproteases comprise a large group of zinc-dependent proteases that cleave basement membrane components such as fibronectin

19. Effect of hydroxyurea (HU) on gelatinization mechanism of type I collagen suspensions
ABSTRACT Mutant hemoglobins thermodynamic phase transitions (HbS, HbC, etc.) have been the causes of serious hemoglobinopathies that have been affecting mankind since the dawn of human race. HbS polymerization is the best known of these transitions and the original cause of sickle cell anemia. Hydroxyurea (HU, NH2CONHOH) is widely used as the main drug admin

20. The interaction of a naturally occurring membranous collagen with high-saline dye solutions – mechanistic features from unusual multi-step biosorption
ABSTRACT It is known that wastewaters containing dyes are very difficult to treat, since many dyes are stable and recalcitrant molecules. In this way, sorption may suitable for effectively remove dyes in this specific application field. In this work, a first approach for using polymeric membranous collagen of fish scales for sorption of saline methylene blue

21. Effect of acute administration of nicotine and ethanol on tooth movement in rats
Abstract The aim of this study was to evaluate the effect of acute administration of nicotine and ethanol on tooth movement in rats. Two hundred rats were divided into eight groups: S: saline; N: nicotine; E: ethanol; NE: nicotine and ethanol; SM: saline with tooth movement; NM: nicotine with tooth movement; EM: ethanol with tooth movement; and NEM: nicotine

22. Denaturation processes of collagen from cow bones as a function of temperature
ABSTRACT The thermal stability of collagen is of great interest for the scientific communities both of medicine and archaeology. In medicine, the interest is focused to the reconstruction and repair of bone and cartilage, given the frequency and importance of pathological situations. In contrast, in archaeology the interest is focused to infer from buried an

23. Differential immunohistochemical expression of type I collagen and matrix metalloproteinase 2 among major salivary glands of young and geriatric mice
Abstract Objective This study aimed to demonstrate the immunohistochemical changes associated with MMP-2 and type 1 collagen separately for the first time in the major salivary glands (the parotid, submaxillary, and sublingual glands) that occur with aging in mice. Material and Methods Fourteen Balb/c white mice (50-80 g) were used in this study. The ani

24. Oral implant osseointegration model in C57Bl/6 mice: microtomographic, histological, histomorphometric and molecular characterization
Abstract Despite the successful clinical application of titanium (Ti) as a biomaterial, the exact cellular and molecular mechanisms responsible for Ti osseointegration remains unclear, especially because of the limited methodological tools available in this field. Objective: In this study, we present a microscopic and molecular characterization of an oral i
