Background& Objective: Micro-vascular proliferation is an important histological feature of brain glioma with more vascular proliferation is present in higher grades of glioma. CD 105 is expressed in new actively proliferating and immature endothelial cells in tumor environment a
Comparison of Quantitative Histologic Micro Vessel Density and 8 Tesla MR Imaging in Patients with Gliomas
D. W. Chakeres, G. A. Christoforidis, A. RayChaudhury, A. Abduljalil, A. Kangarlu, M. Yang The Ohio State University College of Medicine and School of Public Health, Columbus, Ohio, United States Synopsis This study compares the quantitative histologic density of micro vessels ra
Development of a Novel Lung Cancer Detection Technique based upon Micro Vessel Density Analysis
In the medical field, Image processing methods are widely used. It is a method for the improvement of image, the image which is obtained after processing is useful for earlier detection and various stages of cancer. In cancer tumors such as lung cancer time factor is the importan
Micro-vessel Segmentation and Tiny Particle Speed Estimation
On the basis of the flow feature in the micro blood vessels, a method to track the trace of cell movement was proposed in this paper. The algorithm employed the space domain enhancement, adaptive threshold segmentation techniques. For the sake of calculating blood flow, the activ
Effect of Ethanol on Micro-Vessels Diameter and Prevention of Thrombosis
BACKGROUND Microvascular surgery is one of the most important parts of reconstructive surgery. In the present study, the effect of ethanol on microvascular diameter and prevention of thrombosis was evaluated. METHODS Totally, 80 vessels including 40 arteries and 40 veins in right
Study on the Effect of Micro-Vessels on Ablation Effect in Laser Interstitial Brain Tissue Thermal Therapy Based on PID Temperature Control
Laser interstitial thermal therapy (LITT) is an emerging clinical treatment for deep brain tumors, which safe, minimally invasive, and effective. This paper established a three-dimensional model based on the LITT heat transfer model, including tissue, laser fiber, straight tube v
Effects of Mechanical Pumping on the Arterial Pulse Wave Velocity : Peripheral Artery and Micro-vessels
We studied the effect of mechanical pumping on the response of peripheral arteries by focusing on the pulse wave velocity (PWV) in large arterial conduit and micro-vessels. The pressure waveforms were measured simultaneously at the brachial artery (BA), radial artery (RA) and fin
Evaluation of Tumor-Associated Macrophages and Micro-Vessel Density in Verrucous Carcinoma and Squamous Cell Carcinoma of the Oral Cavity
Abstract Background: Tumor-associated macrophages (TAMs) are a crucial cellular component of human tumors, but their exact roles in tumor growth and angiogenesis during cancer progression are still subject to debate. The present study aimed to explore the impact of TAMs on tumor
MRI and micro-CT evaluate the effect of VEGF in a rabbit femoral artery chronic total occlusion
Introduction Chronic total occlusion (CTO) is common in diseased coronary and peripheral arteries. These occlusions are associated with myocardial infarction and ischemia in extremities that can lead to death and amputation, respectively. In many cases, revascularization has yiel
Blood Vessel Adaptation with Fluctuations in Capillary Flow Distribution
Throughout the life of animals and human beings, blood vessel systems are continuously adapting their structures - the diameter of vessel lumina, the thickness of vessel walls, and the number of micro-vessels - to meet the changing metabolic demand of the tissue. The competition
