1. Comparison of Arterial Repair through the Suture, Suture with Fibrin or Cyanoacrylate Adhesive in Ex-Vivo Porcine Aortic Segment
Abstract Introduction: Tissue adhesives can be used as adjacent to sutures to drop or avoid bleeding in cardiovascular operations. Objective: To verify the efficiency of fibrin and cyanoacrylate adhesive to seal arterial sutures and if the adhesives penetrate through suture line to the inner of arteries. Methods: 20 abdominal aorta segments of pigs were d

2. In vitro and in vivo cell tracking of PKH26-labeled osteoblasts cultured on PLDLA scaffolds
Abstract The importance of monitoring in vivo interaction that occurs between cells /bio/tissue recipient in the understanding of tissue regeneration processes becomes ever greater. This study aims to monitor and evaluate the influence of scaffold implants of poly (L-co-D, L lactic acid) - PLDLA synthesized in the laboratory, previously cultured with primary

3. Acute but not chronic metabolic acidosis potentiates the acetylcholine-induced reduction in blood pressure: an endothelium-dependent effect
Metabolic acidosis has profound effects on vascular tone. This study investigated the in vivo effects of acute metabolic acidosis (AMA) and chronic metabolic acidosis (CMA) on hemodynamic parameters and endothelial function. CMA was induced by ad libitum intake of 1% NH4Cl for 7 days, and AMA was induced by a 3-h infusion of 6 M NH4Cl (1 mL/kg, diluted 1:10)

5. Effects of oral administration of S-nitrosothiols and knectic evaluation of the kinetic propensity and resistance to diet induced obessity / Efeitos da administração orogástrica de s-nitrosotióis e avaliação cinética da propensão e resistência à obsidade induzida por dieta
In the present study, the nitric oxide (NO)-associated physiological actions obtained topically on the gastric mucosa and systemically in oral administrations of two NO donors-S-nitrosothiols (RSNOs), S-nitrosoglutathione (GSNO) and S-nitroso-N-acetylcysteine (SNAC) were investigated in animal models. The topical ex vivo administration of RSNOs solutions on

6. Sildenafil prevents the increase of extravascular lung water and pulmonary hypertension after meconium aspiration in newborn piglets
Meconium aspiration syndrome causes respiratory failure after birth and in vivo monitoring of pulmonary edema is difficult. The objective of the present study was to assess hemodynamic changes and edema measured by transcardiopulmonary thermodilution in low weight newborn piglets. Additionally, the effect of early administration of sildenafil (2 mg/kg vo, 30

7. Avaliação das propriedades antigenotóxicas e antioxidantes do flavonóide quercetina e dos carotenóides bixina e norbixina contra os danos no material genético e distúrbios do estado redox causados pelo cloreto de mercúrio e metilmercúrio, in vitro e in vivo / Evaluation of antigenotoxic and antioxidant properties of the flavonoid quercetin and of the carotenoid bixin and norbixin against DNA-damage and alterations of redox status induced by mercury chloride and methylmercury, in vitro and in vivo
Mercury (Hg) is one of the most hazardous metals in the environment and the major process responsible for its toxicity is oxidative damage; its organic form methylmercury (MeHg) presents the highest toxicity. The main way of exposition to Hg is through inhalation by workers occupationally exposed in several industries and/or through consumption of fishes and

8. Desenvolvimento e avaliação da atividade e farmacocinética de nanopartículas lipídicas sólidas contendo a associação de quinina e doxiciclina / Development and evaluation of the activity and pharmacokinetics of solid lipid nanoparticles loaded with the association of Quinine and Doxycycline
Malaria is one of the most devastating tropical diseases caused by intracellular protozoan parasites of the genus Plasmodium. More than 3 billion people live in malarial endemic regions. Five species of Plasmodium (falciparum, vivax, ovale, malariae and knowlesi) cause disease in humans and infection with P. falciparum, the most deadly of these parasites, re

9. Procedure for measurement of conductivity in vivo for develop an anatomic atlas for electric impedance tomography. / Procedimento de medida de condutividade in vivo para desenvolver um atlas anatômico de tomografia por impedância elétrica.
This paper presents a procedure for measuring conductivity in biological tissues of swine chests in vivo. This will allow an increase of resolution in images of EIT, describing the probability of occurrence in such images in a population sample. The EIT is a recently developed technique for obtaining medical images and monitoring biological tissues. Given th

10. Comparison of two purified toxic fractions from Mesobuthus eupeus scorpion venom
Iranian scorpions belong mainly to the Buthidae and Scorpionidae families, distributed into 16 genera and 25 species. In Iran, similar to other parts of the world, there are a few known species of scorpions responsible for severe envenoming; amongst which Mesobuthus eupeus is the most common. Its venom contains several toxin fractions that may affect the ion

11. Desenvolvimento de um sistema minimamente invasivo para monitorar a pressão intracraniana / Development of a minimally invasive system to monitor the intracranial pressure
A pressão intracraniana (PIC) é um dos principais parâmetros neurológicos em animais e humanos. A PIC é uma função da relação entre o conteúdo da caixa craniana (parênquima cerebral, líquido cefalorraquiano e sangue) e o volume do crânio. O aumento da PIC (hipertensão intracraniana) pode acarretar graves efeitos fisiológicos ou até mesmo o ó
