PURPOSE To evaluate the diagnostic value of gadolinium-enhanced dynamic magnetic resonance (MR) imaging of salivary gland tumors and correlate the MR imaging and histopathologic findings. MATERIALS AND METHODS Thirty-three salivary gland tumors in 29 patients were examined preoperatively at gadolinium-enhanced dynamic MR imaging. There were 22 benign and 11 malignant tumors. Dynamic contrast ...

AIM Angiogenesis plays an important role in tumour growth and has been shown to occur around both in situ and invasive tumours. The degree of angiogenesis within tumours depends on the balance of pro-angiogenic and anti-angiogenic factors. One such anti-angiogenic factor is thrombospondin 1 (TSP-1). This study investigates the pattern of expression of TSP-1 in ductal carcinoma in situ (DCIS) of...

PURPOSE AND EXPERIMENTAL DESIGN The purpose is to define intratumoral microvessel density (MVD) and potential biological markers that correlate with inflammatory breast cancer (IBC), we examined MVD, estrogen receptor a (ER) status, MIB-1 proliferation index, p53, and c-erbB-2 by immunohistochemistry in archival specimens from 67 women diagnosed with breast cancer with or without the inflammato...

the basic pathogenic step in the process of tumor growth, invasion and metastasis is tumor-induced angiogenesis. the aim of this study was to evaluate the angiogenesis in colorectal carcinoma by microvascular density (mvd) determination with ihc (immunohistochemistry) method and to determine if and how angiogenesis correlates with clinicopathologic parameters. sixty two archival, paraffin embed...

The molecular biology underlying the metastatic process in ovarian carcinoma remains poorly understood. For other neoplasms, the induction of angiogenesis by malignant cells has been shown to play a pivotal role in the process of tumor proliferation and metastasis. The purpose of this study was to characterize the degree of angiogenesis in epithelial ovarian malignancies and to determine whethe...

BACKGROUND Currently the best prognostic index for operable non-small cell lung cancer (NSCLC) is the TNM staging system. Molecular biology holds the promise of predicting outcome for the individual patient and identifying novel therapeutic targets. Angiogenesis, matrix metalloproteinases (MMP)-2 and -9, and the erb/HER type I tyrosine kinase receptors are all implicated in the pathogenesis of ...

Inhibition of angiogenesis might be a therapeutic approach to prevent joint destruction caused by the overgrowing synovial tissue during chronic joint inflammation. The aim of this study was to investigate angiogenesis in the knee joint of mice with antigen-induced arthritis (AIA) by means of intravital microscopy. In 14 mice (C57BL6/129Sv) intravital microscopic assessment was performed on day...

Gene expression of Dickkopf-3 (Dkk-3) has been shown to be upregulated in tumor endothelium of colorectal cancer (CRC). For the first time, we analyzed Dkk-3 protein expression in CRC and its potential as a marker for neoangiogenesis. We used tissue microarrays (TMAs) to investigate Dkk-3 in microvessels of 403 CRC samples, 318 appropriate adjacent non-cancerous samples and 127 normal colorecta...

We investigated neovasculization effects of embolus-carried human vascular endothelial cell growth factor 165 (VEGF165)-encoded adenovirus (Ad) vector in the hindlimbs of rats with thromboangiitis obliterans (TAO). Rats were equally divided into blank control (I), TAO model (II), embolus (III), Ad-VEGF165 intravascular treatment (IV), Ad-VEGF165 intramuscular treatment (V), and embolus-carried ...
