13. Transcolonic Perirectal NOTES Access (PNA): A feasibility study with survival in swine model
ABSTRACT Transrectal access still has some unsolved issues such as spatial orientation, infection, access and site closure. This study presents a simple technique to perform transcolonic access with survival in a swine model series. A new technique for NOTES perirectal access to perform retroperitoneoscopy, peritoneoscopy, liver and lymphnode biopsies was pe

14. Surgical model pig ex vivo for venous dissection teaching in medical schools
Abstract Purpose: To investigate a method for development of surgical skills in medical students simulating venous dissection in surgical ex vivo pig model. Methods: Prospective, analytical, experimental, controlled study with four stages: selection, theoretical teaching, training and assessment. Sample of 312 students was divided into two groups: Group A

15. Experimental Model for Sutureless Proximal Anastomosis by the Viabahn Open Revascularization TEChnique (VORTEC)
Abstract Introduction: In the treatment of complex aneurysms, debranching is an extra-anatomical revascularization of visceral arteries followed by endograft coverage of the thoracoabdominal aorta. It eliminates the need for a thoracotomy and aortic clamping, but requires the performance of several technically demanding visceral anastomosis. In 2008, Lachat

16. Glomerular loss after arteriovenous and arterial clamping for renal warm ischemia in a swine model
ABSTRACT PURPOSE: To evaluate the glomerular loss after arteriovenous or arterial warm ischemia in a swine model. METHODS: Twenty four pigs were divided into Group Sham (submitted to all surgical steps except the renal ischemia), Group AV (submitted to 30 minutes of warm ischemia by arteriovenous clamping of left kidney vessels), and Group A (submitted to

17. Experimental Model of Saccular Abdominal Aortic Aneurysm in Swines with Pericardium Sac
Abstract Objective: To consider modifications in an experimental model of saccular aortic aneurysm, aiming at better reproducibility, to be used in the development of vascular prostheses. Methods: Experimental study in two phases, developed in the Center of Experimental Surgery and Bioterium (CCEB) of the University of Health Sciences of Alagoas (UNCISAL),

18. Pulse Pressure Variation Patterns in a Swine Model of Hypovolemia under Spontaneous Breathing vs. Invasive Positive-Pressure Ventilation
RESUMO OBJETIVO: Este estudo foi realizado para obtenção do título de Mestre em Medicina, Novembro/2012-Julho/2013. A melhoria do débito cardíaco após a administração de fluidos é conhecida como a capacidade de resposta do fluido. Um parâmetro confiável para sua avaliação é a variação da pressão de pulso, cuja utilidade na previsão da capa

19. Microsurgical training model with nonliving swine head. Alternative for neurosurgical education
PURPOSE: This paper proposes a practical model of microneurosurgical training using a nonliving swine head. METHODS: Fresh porcine heads were obtained from butchery and dissected at our Laboratory of Microsurgery. Brain and skull base surgery were trained under microscopic magnification. RESULTS: Several neurosurgical procedures could be simulated in the no

20. Brazilian minipig as a large-animal model for basic research and stem cell-based tissue engineering. Characterization and in vitro differentiation of bone marrow-derived mesenchymal stem cells
Stem cell-based regenerative medicine is one of the most intensively researched medical issues. Pre-clinical studies in a large-animal model, especially in swine or miniature pigs, are highly relevant to human applications. Mesenchymal stem cells (MSCs) have been isolated and expanded from different sources. Objective: This study aimed at isolating and char

21. Acute inflammatory response to transgastric natural orifice transluminal endoscopic surgery peritoneoscopy: An experimental study in swine
OBJECTIVE: To investigate the impact of transgastric peritoneal access on plasma biomarkers of acute inflammatory response in comparison to laparoscopy. METHODS: This was a prospective and comparative study in a porcine model. Transgastric peritoneal access performed by natural orifice transluminal endoscopic surgery was compared with laparoscopy. Laparot

22. Efeitos fisiológicos da ventilação de alta frequência usando ventilador convencional em um modelo experimental de insuficiência respiratória grave / Physiological effects of high frequency ventilation with conventional ventilator in an experimental model of severe respiratory failure
Introduction: Acute respiratory distress syndrome (ARDS) has a high incidence and mortality between critical ill patients. The mechanical ventilation is the most important support for these patients with ARDS. However, until now there is an important debate about how is the best ventilatory strategy to use, because the mechanical ventilation if not well set

23. Regressão aleatória na detecção de QTL para características de crescimento de suínos / Random regression to detect QTL for growth traits in swine
Muitos estudos são voltados para a busca de QTL (locos de características quantitativas) que afetam características de crescimento em suínos, sendo que a quase totalidade tem encontrado QTL com efeitos significativos. No entanto, a maioria destes estudos utiliza informações referentes a peso corporal em idades específicas ou ganho de peso médio. Dess

24. Effects of biofertilizer rates on the structural, morphogenetic and productive characteristics of Piatã grass
The objective of this study was to investigate the influence of different levels of biofertilizers from cattle and swine manure on the structural, morphogenetic and productive characteristics of Brachiaria brizantha cv. Piatã. The experiment was arranged in a completely randomized factorial design with split plots. The plots were defined by eight treatments
