The aim of this study was to compare magnetic resonance imaging (MRI) and histological estimates of the mean vessel diameter (mVD), the vessel density (Density), and the vessel size index (VSI) obtained in the same tumor-bearing animals. Twenty-seven rats bearing intracranial glioma (C6 or RG2) were imaged by MRI. Changes in transverse relaxations (ΔR 2* and R(2)) were induced by the injection ...

Microvessel density (MVD), an indicator of angiogenesis, has been proposed to predict prognosis of patients with renal cell carcinoma (RCC), but its ability to predict survival of patients with RCC remains controversial. The present study sought to address this question rigorously by systematically reviewing the literature on MVD and RCC prognosis. We identified relevant studies in PubMed, EMBA...

The present study aimed to observe and compare the values of microvessel density (MVD), mast cell microdensity (McMD) and macrophage microdensity (MphMD) in intratumoral areas compared with the advancing edges, and to assess any correlations between these values and the degree and stage of the neoplasia. The cases of 52 patients who were diagnosed with endometrial carcinoma between 2003 and 201...

BACKGROUND Microvessel density (MVD) is a measure of the extent of new blood vessel growth or angiogenesis, which is required for tumor progression. Increased MVD in primary breast cancers appears to adversely affect disease-free survival and overall survival in patients with breast cancer. However, the clinical implications of angiogenesis in breast cancer metastases have not been well studied...

Background -Valvular heart disease (VHD) is common and affects the mitral valve (MV) most frequently. Despite the prevalence of mitral valve disease (MVD), the cellular and molecular pathways that initiate and perpetuate it are not well understood. Methods -K/B.g7 T cell receptor (TCR) transgenic mice spontaneously develop systemic autoantibody-associated autoimmunity, leading to fully-penetran...

Vascular endothelial growth factor (VEGF) and osteopontin (OPN) are suggested to facilitate angiogenesis and vascular remodeling in endometrial receptivity. Determination of the endometrial microvascular density (MVD) is the commonest method used to indirectly assess the levels of vasculogenesis and angiogenesis; however, the associations among VEGF, OPN and MVD remain unclear. Controlled ovari...

Angiogenesis is largely an adaptive response to tissue hypoxia, which occurs in a wide variety of situations. Interestingly, the extent of hypoxia-induces angiogenesis in the cardiac muscle of children diagnosed with congenital cyanotic heart defects is not well established. Thus, the aim of this study was to 1) estimate the cardiac muscle microvessel density (MVD) in children diagnosed with cy...

BACKGROUND coronary artery disease (CAD) is often accompanied by peripheral artery disease. There are patients who are disqualified from surgical approach in the treatment of limb ischaemia due to many comorbidities including severe CAD. AIM to examine whether multilevel intervention (peripheral and coronary) in patients with multi-vessel CAD (MVD) carries a higher in-hospital and long-term r...

The conflicting data are reported on the clinical significance of VEGF deregulation and intensity of angiogenesis in multiple myeloma. The aim of this study was to evaluate the incidence and prognostic significance of VEGF expression and microvessel density (MVD) in multiple myeloma, as well as the relationship of their expression with selected clinical data, histological features, and prolifer...

BACKGROUND Multivessel coronary disease (MVD) occurs in approximately 40-65% of patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI), and is associated with significantly increased morbidity and mortality rates. AIM To evaluate the impact of MVD on in-hospital and long-term clinical outcomes in patients with STEMI and PCI, and ...
