Purpose To characterize the microstructure underlying the parapapillary deep-layer microvasculature dropout (MvD) identified by optical coherence tomography (OCT) angiography (OCTA) in eyes with primary open-angle glaucoma (POAG). Methods Parapapillary MvD was defined as a focal sectoral capillary dropout without any visible microvascular network identified in deep-layer en face images obtain...

In the Indian subcontinent, patients having multivalvular disease (MVD) continue to be a frequent entity whose evaluation and management are challenging. MVD is the combination of stenosis or regurgitation, or both, on two or more valves of the heart.1 There are a large number of possible combinations in patients with MVD, and this heterogeneity leads to availability of limited data.2,3 The Eur...

BACKGROUND Prostate cancer is a major concern of public health. Microvascular density (MVD) is one of the prognostic markers for various solid cancers. Matrix metalloproteinase 11 (MMP11) plays an important role in angiogenesis and changes in its expression level are known to be associated with tumor progression and clinical outcome. AIM To investigate the relationship between MVD and MMP11 e...

AIMS Angiogenesis, an important prognostic factor in several tumours, is a complex event mediated by angiogenic factors released from cancer cells and host immune cells. Among the host immune cells, a role has been implicated for mast cells in tumour progression via promoting angiogenesis. Data have been recorded that indicate a correlation between intratumoral neovascularisation, as assessed b...

BACKGROUND Abnormal intracellular Ca2+ homeostasis occurs in chronic atrial fibrillation(AF). The intracellular Ca2+ concentration is regulated by ryanodine and inositol 1,4,5-trisphosphate (IP3) receptors. Changes occur in ryanodine receptors in atrial tissue from patients in chronic AF. Whether AF patients have alterations in atrial IP3 receptors was investigated. METHODS IP3 receptor expre...

This study aimed to determine the expression of integrin β1 and vascular endothelial growth factor (VEGF) and microvascular density (MVD) by CD105 staining in hypopharyngeal squamous cell carcinoma to determine their association with clinicopathologic characteristics, and to determine their role and the effects of their interactions in the development and progression of hypopharyngeal squamous ...

Background. Reliable immunohistochemical assays to assess the definitive role of mast cells (MCs) and angiogenesis in the pathogenesis of oral reactive lesions are generally not available. The aim of the present study was to evaluate mast cell counts (MCC) and microvessel density (MVD) in oral reactive lesions and determine the correlation between MCC and MVD. Methods. Seventy-five cases of rea...

INTRODUCTION Angiogenesis plays an important role in the uncontrolled proliferation, invasion and metastasis of cancers. Increased microvessel density (MVD) is known to be associated with evolution and aggressiveness of the endometrial carcinoma (EC). The formation of new vessels depends on interactions between various hormones and growth factors. VEGF is one of the most known promoters of angi...

The current European Society of Cardiology guidelines for revascularization confer a Class I indication (level of evidence A) for coronary artery bypass grafting (CABG) in multi-vessel coronary artery disease (MVD). However, due to recent advances in percutaneous coronary intervention (PCI), with new generation drug-eluting stents (DES) and more potent antiplatelet agents, in addition to increa...

Tumor angiogenesis is believed to be a prognostic indicator associated with tumor growth and metastasis. Microvessel density (MVD) assessment with common endothelial markers such as CD34 has been found to influence prognosis among endometrial carcinoma patients. The CD105/endoglin antibody has been reported to preferentially bind to proliferated endothelial cells in tissues participating in ang...
