In this study, we compared mast cell tryptase and CD31 expression between odontogenic tumors with the aim of predicting the clinical behavior of these lesions at the time of initial biopsy. We also evaluated the correlation between mast cell tryptase and CD31 expression to clarify the role of mast cells (MCs) in the growth of odontogenic tumors. Immunohistochemical staining with anti-MC tryptas...

Recent observations have underscored the biologic relevance of intratumoral angiogenesis and its potential impact on prognosis. Increased bone marrow angiogenesis has been demonstrated in a variety of hematologic disorders, including multiple myeloma. The extent and prognostic significance of bone marrow angiogenesis in 114 patients with myelofibrosis with myeloid metaplasia (MMM) was investiga...

The aim of this study was to quantify the distribution microvessels and mast cells in all three parts trigeminal ganglion (TG). Statistical analyses were applied investigate possible micromorphological regional differences their density. Five serially sectioned human TGs prepared for CD34 cell tryptase immunostaining. following quantifications performed microscopic fields TG: microvessel densit...

Tumour growth is angiogenesis-dependent; brain tumours have more intense neovascularisation than other tumours and produce basic fibroblast growth factor, a potent angiogenic mediator. Because little is known about the release of basic fibroblast growth factor from brain tumours into extracellular fluids, we tested cerebrospinal fluid (CSF) from 26 children and young adults with brain tumours a...

background and objectives: retinoblastoma is the most common intraocular pediatric malignancy. angiogenic factor expression such as vegf (vascular endothelial growth factor) in retinoblastoma can be confirmatory angiogenic potential of this tumor. this study was performed to determine the role of angiogenesis in local invasion of retinoblastoma and its correlation with patients’ survival. mater...

To explore the effect of electrical stimulation combined with pelvic floor muscle training on improvement urethral function in rats stress urinary incontinence and to further study its possible mechanism. 48 were randomly divided into blank control group, model treatment group group. The rehabilitation was treated after successful modeling. sneeze test, urodynamics strength measurement used det...

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 techniques-even when it is histologic...

Hodgkin lymphoma (HL) differs from other lymphomas because the malignant cells, the Hodgkin and Reed–Sternberg (HRS) cells, are in minority and the majority of the tissue consists of surrounding benign cells, for example, eosinophilic granulocytes and mast cells, fibrosis and a varying number of microvessels. It has recently been reported that angiogenesis correlates to poor prognosis in HL. We...

PURPOSE Pathologic angiogenesis has been correlated with tumor growth, dissemination, metastasis, and prognosis in solid tumors including breast cancer. Angiogenesis has also been implicated in the pathophysiology of, and shown to be a therapeutic target in tumors arising in the bone marrow. The status of angiogenesis in the bone marrow of breast cancer patients is unknown. The aim of this stud...
