Studies on the role of vascular endothelial growth factor (VEGF) as the most potent angiogenic factor in disease progression of nasopharyngeal carcinoma (NPC) remain limited, partly be due to the geographical distribution of the disease. However, it has never been reported from Indonesian population despite its common incidence. Therefore, we aimed to study the possible prognostic value of VEGF...

BACKGROUND Vascular endothelial growth factor (VEGF) levels are raised in the serum of patients with oesophageal carcinoma. The aim of this study was to evaluate the tumour microvasculature and the role of tumour-associated macrophages in VEGF production after neoadjuvant chemoradiotherapy and surgery for oesophageal cancer. METHODS Sections from 92 consecutively resected oesophageal tumours ...

In research areas such as decision support systems, one of the crucial features is the ability to automatically explain decisions. However, this ability does not typically play a large role in computer games. Here, I suggest that this situation will change: research on the automatic generation of explanations will have real import for many types of computer games. I discuss four possible ways t...

To investigate the direct effect of leukocyte adherence to microvessel walls on microvessel permeability, we developed a method to measure changes in hydraulic conductivity (L(p)) before and after leukocyte adhesion in individually perfused venular microvessels in frog mesentery. In 19 microvessels that were initially free of leukocyte sticking or rolling along the vessel wall, control L(p) was...

We previously reported that overexpression of DHX32 contributes to the growth and metastasis of colorectal cancer (CRC). However, the underlying mechanism is not largely characterized. Herein, we reported that DHX32 in CRC cells upregulated expression of vascular endothelial growth factor A (VEGFA) at the transcription level through interacting with and stabilizing β-catenin. This promoted the ...

We have previously reported the production of endothelin, a potent vasoconstrictor peptide, by porcine cerebral microvessel endothelia and suggested its important role in the regulation of local blood flow within the brain. In our present study, radioimmunoassay with anti-porcine endothelin antiserum revealed that endothelin, produced by cerebral microvessel endothelia grown on a filter, is rel...

The development of engineered microvessels with clinically relevant characteristics is a critical step toward the creation of engineered myocardium. Alignment is one such characteristic that must be achieved, as it both mimics native capillary beds and provides natural inlet and outlet sides for perfusion. A second characteristic that is currently deficient is cross-sectional lumen density, typ...

Introduction. There is a problem with commonly accepted parameters for microcirculation. This problem is due to many used mathematical models. The aim of notes to reveal that hypothesis about stochasticity of microflow leads to the uniqueness of mathematical equations for passage throughout microcirculation. Thus stochasticity could be a motivation for the choice of parameters of microcirculati...
