13. Efeito de características estruturais da quitosana sobre sua interação com filmes de Langmuir como modelo de biomembrana / Effects from the structural characteristics of chitosan on its interaction in Langmuir films as biomembrane models.
Chitosans are polysaccharides used in medicine, pharmacy, dentistry and in the inhibition of microorganisms growth (eg. as bactericidal agent). In these applications their action should depend on the interaction with cell membranes, which is difficult to verify because isolating a membrane is not easy. An alternative is to investigate the interaction with me

14. Pancreatite aguda sem etiologia aparente: a microlitíase deve ser pesquisada?
In a large number of patients, with episodes of acute pancreatitis the etiology is not identified, even after initial clinical history, detailed physical examination, laboratory tests and biochemical exams and an transabdominal ultrasound. This patient are considered with a unexplained acute pancreatitis. In this cases the treatment is restricted to improvem

15. Internal jugular vein cannulation: an ultrasound-guided technique versus a landmark-guided technique
OBJECTIVES: To compare the landmark-guided technique versus the ultrasound-guided technique for internal jugular vein cannulation in spontaneously breathing patients. METHODS: A total of 380 patients who required internal jugular vein cannulation were randomly assigned to receive internal jugular vein cannulation using either the landmark- or ultrasound-guid

16. Precisão da ultra-sonografia bidimensional convencional e da ultra-sonografia tridimensional na avaliação do nível da lesão em fetos com espinha bífida aberta / Precision of conventional two-dimensional and threedimensional sonography in the evaluation of the lesion level in fetuses with open spina bifida
Introduction: Incidence of spina bifida is about 0.5 to 0.8 per 1,000 births, with neonatal mortality around 33% and handicap in about 65% of survivors. Sonography diagnoses about 80% to 100% of cases. Objective: To evaluate the precision of both two-dimensional and three-dimensional sonography in determining vertebral lesion level (the first open vertebra)

18. Evaluation of postoperative complications in bitches submitted to ovariohysterectomy. / Avaliação das complicações pós-operatórias em cadelas submetidas à ovário-histerectomia.
This study aimed to evaluate the postoperative complications in 20 bitches previously submitted to ovariohysterectomy, correct these complications by surgery, and correlate the findings observed in preoperative diagnostic exams with those found during exploratory laparotomy. The animals were evaluated from the first day to the third month after consultation.

19. A influência do diagnóstico pré-natal na formação de possíveis psicopatologias do laço pais-bebê
With the technological development in the last decades, notably with the introduction of the use of ultrasound in pre-natal examinations, it is known today that the fetus has multiple skills. The development of prenatal diagnosis allowed the detection of numerous disabilities during pregnancy and also to monitor the pregnancies that may offer a particular ri

20. Uma aplicação stand-alone multiplataforma para a quantificação semi-automatica da perfusão miocardica em imagens de ecocardiografia com contraste / A stand-alone multiplatform software apllication for semiautomatic quantification of myocardial perfusion on contrast echocardiografic images
Os scanners ultra-sônicos atuais oferecem ferramentas específicas para estudos de Ecocardiografia do Miocárdio por Contraste de Microbolhas (ECM) e apesar do potencial comprovado para a análise quantitativa não invasiva da perfusão miocárdica, seu uso se restringe praticamente à interpretação qualitativa (visual) das imagens clínicas. O objetivo d

21. THE USE OF CYANOACRYLATE ADHESIVE FOR FIXATION OF CORNEAL AUTO E ALOIMPLANTS PRESERVED IN 98% GLYCERIN IN THE PENETRATING KERATOPLASTY IN RABBITS / USO DE ADESIVO DE CIANOACRILATO PARA A FIXAÇÃO DE BOTÃO CORNEAL AUTÓGENO OU ALÓGENO CONSERVADO EM GLICERINA A 98% NA CERATOPLASTIA PENETRANTE EM COELHOS.
The present research had the objective to evaluate the use of an n-butil cyanoacrylate in the fixation and maintenance of corneal autografts and aloimplants in the penetrating keratoplasty. There were used eight adult rabbits divided in two groups: the group I adhesive (GI 4 animals) and group II suture (GII 4 animals). In the GI, performed in the left eye,

22. Sistema multicanal de geração e recepção de ondas ultra-sonicas para transdutor matricial linear / Multichannel system for generation and detection of ultrasonic waves with a linear array transducer
Ultrasound in medicine has gone through great evolution in the last few decades and has occupied important position as a tool for therapy and diagnosis. This is due to the ultrasound equipment be of relatively low-cost, ultrasound is a non-ionizing radiation, is a non-invasive imaging method, and the images are created and seen in real time. It is common the
