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...

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...

objective(s): the aim of this study is to determine the effects of progesterone treatment on the survival of random skin flaps. materials and methods: mcfarlane flaps were established and 40 male rats were randomly assigned to the progesterone-treated as the test group or normal saline-treated as the control group. progesterone or normal saline (10 mg/kg) was administered intraperitoneally once...

background: beta-adrenergic blocking agents have been broadly used for treatment of many cardiovascular diseases such as arterial hypertension and ischemic heart failure. anti-tumoral, anti-inflammatory and anti-angiogenesis effects of propranolol (a non-selective beta-adrenergic blocker) have been shown. angiogenesis (replenish of the pre-existing vascular networks) plays a critical role in so...

background: we investigated coronary angiogenesis and serum vascular endothelial growth factor (vegf) and its soluble receptor-1 (sflt-1) concentrations in two-kidney one-clip (2k1c) hypertensive rats before and after reversal of hypertension. methods: the animal groups were: (i) sham-clipped for 12 weeks; (ii) 2k1c for 12 weeks; (iii) sham-clipped for 12 weeks and unclipped for 12 weeks; and (...

background angiogenesis is an important biological process involved in the proliferation of endothelial cells, tumor growth and metastasis. vascular endothelial growth factor (vegf) is considered as a prominent regulator of angiogenesis which exerts the aforementioned effect(s) through its respective receptors (vegfr1 and vegfr2). vegf receptors are targeted as a therapeutic candidate for cance...
