1. Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting
ABSTRACT Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving the endothelium of veins during high-pressure distention. Methods: Human saphenous veins (SVs)

4. Determining attributed factors of hearing handicap in individuals with auditory sensory and neural pathology
Abstract Introduction: There is a modest relationship between speech perception skills and perceived hearing handicap in individuals with hearing loss. In this study, an attempt is made at linking psychoacoustic results and speech perception skills to understand the subjective handicap and quality of life. Objective: To investigate how speech perception in

5. Effects of Intensification of Vaporization by Decompression to the Vacuum (IVDV) and frying on physicochemical, structural, thermal, and rheological properties of chickpea (Cicer arietinum L.) powder
Abstract Hard textural attributes of chickpea necessitate the employment of specialized pretreatment prior to roasting. As compared to frying, the Intensification of Vaporization by Decompression to the Vacuum (IVDV) as a vacuum expansion (VE) technique was utilized to improve and preserve the nutritional, textural, and structural properties of chickpeas. It

6. Laser topoguiado como tratamento de ectasia pós lasik
RESUMO O laser in situ keratomileusis (LASIK) é o método cirúrgico refrativo mais realizado no mundo com excelentes resultados, porém tal método não é isento de riscos. A ectasia pós LASIK é uma complicação grave e se caracteriza por um aumento progressivo da curvatura e afinamento da córnea, resultando em astigmatismo irregular e diminuição da

7. ASPECTOS ESTRUTURAIS DE ESFERAS DE QUITOSANA/PVA RETICULADAS COM GLUTARALDEÍDO SUBMETIDAS A DIFERENTES TRATAMENTOS TÉRMICOS
Chitosan is a biopolymer derived from chitin and the most abundant polysaccharide in nature after cellulose. This biopolymer has been applied in different areas due its biodegradability and biocompatibility properties. Modifications of chitosan structure by cross-linking chemical agents can alter its physical, chemical, and morphological characteristics. The

10. Hibridación y diferenciación discursiva entre kleinismo y lacanismo (Uruguay, 1955-1982)
As ideias lacanianas chegam ao Uruguai na década de 1960, em um contexto de hegemonia kleiniana. Neste trabalho, descrevemos os processos e os fenômenos discursivos a partir dos quais o lacanismo se relaciona e se articula com o kleinismo da época. Para realizar esta pesquisa, construiu-se um corpus de dados discursivos a partir de casos clínicos e artig

12. Cross-linked coacervates of cashew gum and gelatin in the encapsulation of pequi oil
RESUMO: O óleo de pequi é rico em compostos bioativos, os quais podem ser encapsulados para aumentar a proteção a fatores extrínsecos. A tecnologia de microencapsulamento, além de retardar a degradação do composto ativo, possibilita mascarar aromas e sabores indesejáveis. A coacervação complexa é uma técnica baseada na interação eletrostátic
