PURPOSE Vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF)-I, and growth hormone (GH) are major regulators of physical growth, as well as normal and pathologic retinal development. Ocular tissues are protected by the blood-ocular barrier. This study was conducted to test the hypothesis that the ontogenic profiles of VEGF, IGF-I, and GH in the rat serum, vitreous fluid, ...

OBJECTIVE To evaluate the changes and the prognostic value of serum vascular endothelial growth factor (VEGF) in patients with differentiated thyroid cancer (DTC). SUBJECTS AND METHODS A total of 79 patients with DTC and 30 healthy individuals were divided into four groups: (1) a healthy control group (n = 30); (2) DTC without recurrence (n = 35; 23 papillary, 12 follicular); (3) DTC with loc...

Aim of the study Vascular endothelial growth factor (VEGF) is one of the parameters that has been studied in differential diagnosis of malignant fluids. This study is aimed at evaluate applicability of serum, fluid VEGF level and fluid to serum VEGF ratio in the diagnosis of malignant pleural mesothelioma (MPM). Material and methods The patients with pleural effusion over age of 18, between 2...

BACKGROUND Soluble vascular endothelial growth factor (VEGF) is a promising biomarker in monitoring rheumatoid arthritis (RA), but studies of pre-analytical and biologic variability are few. METHODS VEGF was measured by ELISA methods in serum and plasma from healthy persons and RA patients. Pre-analytical factors were investigated. A reference interval for VEGF was established in serum and pl...

Angiogenesis is controlled by anti-angiogenic factors as well as by angiogenic factors, such as VEGF (vascular endothelial growth factor) and HGF (hepatocyte growth factor). Endostatin, a potent endogenous angiogenesis inhibitor, is known to inhibit endothelial proliferation and suppress tumour growth. However, to date, little is known about the pathophysiology of endostatin in ischaemia/reperf...

We read with interest the article by Seko and colleagues [1], who document that serum levels of endostatin and VEGF (vascular endothelial growth factor) are increased markedly in patients with acute myocardial infarction, but subsequently decrease significantly by early reperfusion. We would like to point out important limitations in their findings not addressed in the study. This relates entir...

BACKGROUND Elevated concentrations of vascular endothelial growth factor (VEGF) have been detected in the peritoneal fluid of patients with endometriosis. Furthermore, it was postulated that VEGF is involved in the development of endometriotic lesions. The present study is aimed at determining whether high levels of VEGF could also be found in the serum of patients with endometriosis. METHODS...

Preclinical study results suggest that neurotrophic peptides like nerve growth factor (NGF) and vascular endothelial growth factor A (VEGF-A) may be associated with symptoms of addictive behavior like withdrawal symptoms and rewarding effects. We investigated alterations in NGF and VEGF-A serum levels in opiate-dependent patients (25 male patients), who received diamorphine (DAM, heroin) treatm...
