We explored the effect of astaxanthin on vascular endothelial growth factor in the aqueous humor, by measuring vascular endothelial growth factor levels and oxidation-related parameters, including O2 (•-) scavenging activity, H2O2 level, and total hydroperoxide level in the aqueous humor, obtained from 35 patients before and after astaxanthin administration. We evaluated the relationship betwee...
objective: envenomation by heamotoxic snakes constituted a critical health occurrence in the world. bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. it is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. this study was to evaluate the...
Endothelial adherens junctions maintain vascular integrity. Arteries and veins differ in their permeability but whether organization and strength of their adherens junctions vary has not been demonstrated in vivo. Here we report that vascular endothelial cadherin, an endothelial specific adhesion protein located at adherens junctions, is phosphorylated in Y658 and Y685 in vivo in veins but not ...
while a wide array of pathological changes occur in cerebral arteries following subarachnoid hemorrhage (sah), the most consistent is endothelial damage. since the endothelium normally modulates reflexes that influence vascular tone, any damage to it may represent a significant contributor to cerebral vasospasm following sah. this experimental study investigates the correlation between endothel...
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: Ranibizumab is anti-vascular endothelial growth factor (anti-VEGF) agent made for intraocular use, like smaller antibody fragment that can penetrate retina. Intravitreal ranibizumab therapy has been accepted as a predominant treatment CNV in recent years.
PURPOSE Loss of vascular barrier function has been observed shortly following vascular-targeting photodynamic therapy. However, the mechanism involved in this event is still not clear, and the therapeutic implications associated with this pathophysiologic change have not been fully explored. EXPERIMENTAL DESIGN The effect of vascular-targeting photodynamic therapy on vascular barrier function...
Objective(s): Herbal medicines are promising cancer preventive candidates. It has been shown that Punica granatum L. could inhibit angiogenesis and tumor invasion. In this study, we investigated whether the anti-angiogenic effect of pomegranate peel extract (PPE) is partly attributable to Peroxisome proliferator-activated receptors (PPARs) activation in the Human Umbilical Vein Endothelial Cell...
