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)

2. Saphenous Vein Vasa Vasorum as a Potential Target for Perivascular Fat-Derived Factors
Abstract Perivascular adipose tissue (PVAT) is a source of factors affecting vasomotor tone with the potential to play a role in the performance of saphenous vein (SV) bypass grafts. As these factors have been described as having constrictor or relaxant effects, they may be considered either beneficial or detrimental. The close proximity of PVAT to the adven

3. Role of Urotensin-II in Saphenous Vein Graft Disease
Abstract Objective: To elucidate the effect of diabetes mellitus (DM) on the atherosclerotic process in saphenous vein grafts by determining urotensin-II (U-II) levels in harvested saphenous veins of patients who underwent coronary artery bypass grafting (CABG). Methods: Coronary artery disease (CAD) patients who underwent CABG were divided into two groups

5. Development of the urinary system in guinea pig females (Cavia porcellus)
RESUMO: Os porquinhos-da-índia são modelos animais amplamente utilizados em pesquisas relacionadas a biologia do desenvolvimento. O objetivo deste trabalho foi demonstrar o processo de formação e diferenciação dos órgãos urinários em fêmeas da espécie no período pré-natal. Foram utilizadas quatro fêmeas aos 25, 30, 45 e >65 DG (dias de gestaç�

6. Morphological study of the gastrointestinal tract of Larimichthys crocea (Acanthopterygii: Perciformes)
ABSTRACT The present study aimed to investigate the macroscopic and histological structure of the gastrointestinal tract (GIT) of Larimichthys crocea (Richardson, 1846). It consists of esophagus, stomach regions, pyloric caeca, intestinal regions, and rectum. Sixteen tubular light yellowish pyloric caeca of similar sizes were observed in all individuals. The

7. Characterisation of the vascular pathology in Sigmodon hispidus (Rodentia: Cricetidae) following experimental infection with Angiostrongylus costaricensis (Nematoda: Metastrongylidae)
BACKGROUND Angiostrongylus costaricensis is a nematode that causes human abdominal angiostrongyliasis, a disease found mainly in Latin American countries and particularly in Brazil and Costa Rica. Its life cycle involves exploitation of both invertebrate and vertebrate hosts. Its natural reservoir is a vertebrate host, the cotton rat Sigmodon hispidus. The

8. Sinusoidal Constriction and Vascular Hypertrophy in the Diabetes-Induced Rabbit Penis
Objective To assess the morphological changes of penile vascular structures and the corpus cavernosum area in alloxan-induced diabetic rabbits. Materials and Methods Twenty male rabbits (2 months old) were divided into two groups with 10 rabbits each, the control group (CG) and the diabetic group (DG). The animals from DG received an intravenous injection

9. Enxerto sintético e biológico, com e sem preenchimento de veia jugular externa, no reparo de nervo periférico em ratos / Syntetic and biological graft, filled with the external jugular vein in the repair of peripheral nerve in rats
Despite the development of technology involved in peripheral nerve regeneration, there is no technique that presents a recovery of the nervous tissue with completely satisfactory results. This fact arouses interest of several researchers around the word. Although the autologous nerve grafting is the current gold standard for the repair of large nerve gaps, o

10. Histomorphometric and sympathetic innervation of the human internal thoracic artery
INTRODUCTION: Internal thoracic artery (ITA) is an established arterial graft for the coronary artery by-pass surgery. Special micro-anatomical features of the ITA wall may protect it from age related pathological changes. One of the complications seen after coronary artery bypass grafting is vasospasm. Sympathetic nerves may be involved in vasospasm. OBJECT

11. Postangioplasty restenosis : a practical model in the porcine carotid artery
Transluminal coronary angioplasty is a routine therapeutic intervention in coronary heart disease. Despite the high rate of primary success, restenosis continues to be its major limitation. Porcine models have been considered to be the most adequate experimental models for studying restenosis. One limitation of porcine models is the need for radiological gui

12. Intravascular ultrasound: tridimensional quantification and analysis / Análise e quantificação tridimensional em imagens de ultra-som intravascular
INTRODUCTION: Several efforts for in vivo atherosclerotic plaque estimation has been realized worldwide. Current methods for related application are based on spectral analysis of backscattered ultrasound signals before intravascular image formation (IVUS), once there is not available techniques to perform composition analysis only from IVUS images. On this s
