It is well known that the metabolic factors play an important role in the regulation of angiogenesis. Increased metabolic activity leads to decreased oxygen levels and causes tissue hypoxia. Hypoxia starts different signals to stimulate angiogenesis and promotes oxygen delivery to tissues. It has been suggested that released adenosine from hypoxic tissues plays a vital role in angiogenesis. ...

The role of angiogenic molecules, like vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) in tumor angiogenesis was well confirmed. Photodynamic therapy (PDT) action is, to very high degree, based on tumor vasculature damage. Therefore, it seemed to be important to evaluate growth factor receptors after PDT. The extent of receptor expression was studied by immuno-histo...

background:  new discoveries about the pathophysiology changed the concept that all forms of osteoarthritis are alike; this lead to the delineation of different phenotypes such as age, trauma or obese related forms. we aim to compare soluble mediator profiles in primary knee and posttraumatic wrist osteoarthritis. based on the general faster progression rate of wrist osteoarthritis, we hypothes...
