13. Effects of diabetes on myocardial capillary density and serum angiogenesis biomarkers in male rats
INTRODUCTION: Cardiovascular disease is one of the main causes of mortality and morbidity in diabetic patients. This study evaluated the effects of diabetes on myocardial capillary density and several serum angiogenic factors including nitric oxide, vascular endothelial growth factor, and soluble vascular endothelial growth factor receptors. METHODS: Twelve

14. Analysis of angiogenic factors and cyclooxygenase-2 expression in cartilaginous tumors: clinical and histological correlation
OBJECTIVES: To study the role of angiogenesis and cyclooxygenase-2 expression in cartilaginous tumors and correlate these factors with prognosis. INTRODUCTION: For chondrosarcoma, the histological grade is the current standard for predicting tumor outcome. However, a low-grade chondrosarcoma can follow an aggressive course-as monitored by sequential imaging

15. Angiogenesis and experimental hepatic fibrosis
Angiogenesis is a basic change occurring during repair by granulation tissue. This process seems to precede fibrosis formation in most types of chronic liver disease. To examine its presence and significance in different types of hepatic insults, this paper sought to identify the presence, evolution and peculiarities of angiogenesis in the most common experi

16. Angiogenesis and schistosomiasis
Angiogenesis has been recognised as a precursor of fibrosis in several pathologic conditions. Its participation has been demonstrated in schistosomiasis, both during periovular granuloma formation and in the genesis of schistosomal periportal fibrosis. Paradoxically, proliferation of new blood vessels, accompanied by production of vascular-endothelial growth

17. Genetic variability of vascular endothelial growth factor and prognosis of head and neck cancer in a Brazilian population
Vascular endothelial growth factor (VEGF) is one of the most potent endothelial cell mitogens and plays a critical role in angiogenesis. Polymorphisms in this gene have been evaluated in patients with several types of cancer. The objectives of this study were to determine if there was an association of the -1154G/A polymorphism of the VEGF gene with head and

18. Vascular growth endothelial factor (VEGF) and microvessel density in human osteosarcomas. / Estudo do fator de crescimento endotelial vascular VEGF e da densidade de microvasos em osteossarcomas humanos.
INTRODUCTION: The role of angiogenesis as a prognostic indicator in cancer has been extensively studied in recent times with several studies demonstrating a positive correlation for various malignant tumours. However, the role of angiogenesis in osteosarcoma remains a topic of debate. AIM : evaluate the significance of intratumoral microvessel density (MVD)

19. Avaliação da expressão dos membros da familia de fatores de crescimento endotelial vascular e seus receptores e da densidade vascular sanguínea e linfática, em lesões malignas e benignas da tireóide / Evaluation of the family members of vascular endothelial growth factors and their receptors and blood and lymphatic vascular density in malignant and benign thyroid lesions
As neoplasias tireoidianas são importante causa de morbi-mortalidade. A patogênese da disseminação neoplásica pelo organismo é um complexo e intrigante processo pelo qual grande parte das neoplasias malignas se dissemina, a partir de um sítio de origem, para diferentes partes do organismo, utilizando como vias preferenciais os sistemas vasculares veno

20. Fator de crescimento do endotélio vascular na viabilidade do retalho musculofasciocutâneo abdominal transverso do músculo reto do abdome, após abdominoplastia, em ratos / Vascular endothelial growth factor on the transverse rectus abdominis myocutaneous flap viability after abdominoplasty in rats
Introduction: Transverse rectus abdominis musculocutaneous (TRAM) flap may present necrosis, in pacients with risk factors. Abdominoplasty is a risk factor due to disruption and transection of vascular perforators. Perspectives on naked plasmid DNA encoding vascular endothelial growth factor (VEGF) as gene therapy for angiogenesis and neovascularization of T

21. Estudo imunoistoquímico, tomográfico e histológico sobre a remodelação de enxertos ósseos onlay. Parte II (Calota Craniana) / Immunoshistochemical, tomographic and histological study on onlay bone grafts remodeling. Part II - Calvarial bone
Several studies have discussed factors that govern the longevity of onlay bone grafts. However, little information has been made available on molecular events that occur over time. Cranial bone grafts have been reported to produce greater responses compared to other donor regions in maxillofacial reconstructions, but necessary scientific verification was sti

22. Produção de VEGF e HIF-1? em pacientes com carcinoma de mama localmente avançado submetidas à quimioterapia neoadjuvante. / Production of VEGF and HIF-1? in patients with locally advanced breast cancer primarily submitted to neoadjuvant chemotherapy.
To determine the predictive and prognostic value of vascular endothelial growth factor (VEGF) and Hypoxia-inducible factor-1 (HIF-1?) for relapse-free survival (RFS) and overall survival (OS) in locally advanced breast cancer (LABC) primarily submitted to neoadjuvant chemotherapy. MATERIALS AND METHODS: VEGF and HIF were quantitatively measured in plasma sam

23. Identificação da expressão do vascular endothelial growth factor (VEGF) pela contagem de células marcadas imunoistoquimicamente no omento de ratos após ligadura arterial e após ligadura venosa
O sistema cardiovascular está estrutural e funcionalmente disposto de modo “circular”. Situações de obstrução do fluxo sanguíneo determinam o aparecimento de mecanismos que visam suplantar tais interrupções e manter a circularidade íntegra. À nível molecular, o principal elemento envolvido nestes mecanismos é o Vascular Endothelial Growth Fac

24. Expressão de fatores angiogênicos em corpo lúteo cíclico e superovulado de búfalas / Expression of angiogenic factors in cyclic and superovulated bufallo corpus luteum
Biotechniques can be an effective way of improving reproduction efficiency and enhancing the production of genetically superior animals. The superovulatory treatment is a common technique aiming to spread desired genetical material, although its use in buffalos still presents limitations, mainly the low embryo recovery rate. The corpus luteum (CL) is a tempo
