The toxicities of ROUNDUP and its component chemicals, glyphosate (N-phosphonomethylglycine) and polyoxyethyleneamine (POEA), were determined at 0, 1, 3, 6 and 24 h following administration to rats. The intratracheal administration of glyphosate (0.2 g/kg), POEA (0.1 g/kg), a mixture of glyphosate (0.2 g/kg) + POEA (0.1 g/kg), or ROUNDUP (containing 0.2(More)
PURPOSE To examine the impact of photodynamic therapy (PDT) on pigment epithelium derived factor (PEDF) expression in human choroidal neovascularization (CNV) membranes with regard to vascular endothelial growth factor (VEGF) expression. DESIGN Interventional case series. METHODS Retrospective review of interventional case series of 42 patients (42(More)
We investigated the effect of two oral (p.o.) doses of cicletanine (5 and 30 mg/kg/day) for 4 weeks on urinary excretion (UKE), renal concentration (RKC) of kallikrein, and prostaglandin E2 (PGE2) and 6-keto-PGF1 alpha urinary excretion of stroke-prone (SP) spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY) rats submitted to a high sodium(More)
Brain metastases are the most common cause of death in patients with metastatic melanoma, and the RAF-MEK-ERK and PI3K-AKT signaling pathways are key players in melanoma progression and drug resistance. The BRAF inhibitor vemurafenib significantly improved overall survival. However, brain metastases still limit the effectiveness of this therapy. In a series(More)
Endostatin is an endogenous angiogenesis inhibitor which requires E-selectin for its antiangiogenic activity. The aim of this study was to investigate the expression of endostatin in human choroidal neovascular membranes (CNV) secondary to age-related macular degeneration (AMD) with regard to vascularization and proliferative activity. An interventional(More)
OBJECTIVE To examine the impact of photodynamic therapy (PDT) on angiogenesis in human choroidal neovascular membranes with respect to vascular endothelial growth factor (VEGF) expression, proliferation, and vascularization. METHODS Retrospective review of an interventional case series of 50 patients (50 eyes) who underwent removal of choroidal(More)
OBJECTIVE To evaluate the effect of bevacizumab (Avastin; Genentech, Inc, South San Francisco, California) on inflammation and proliferation in human choroidal neovascularization (CNV) secondary to age-related macular degeneration. METHODS Retrospective review of interventional series of 38 patients who underwent choroidal neaovascular membrane (CNVM)(More)
The transcription factor SOX2 has been extensively studied for its role in embryonic stem cell self-renewal and pluripotency. More recent data suggest oncogenic functions of SOX2 and demonstrate expression in several carcinoma types, predominantly of squamous cell origin. The gene SOX2 is located at chromosome 3q26, a region that is frequently amplified in(More)
AIM To evaluate the effect of verteporfin photodynamic therapy (PDT) on endostatin with regard to expression of vascular endothelial growth factor (VEGF) in human choroidal neovascular membranes (CNVs) secondary to age-related macular degeneration. METHODS A retrospective review of an interventional case series of 68 patients who underwent removal of CNV.(More)
PURPOSE To examine the short- and long-term consequences of verteporfin photodynamic therapy (PDT) on inflammation with regard to infiltration of macrophages and leukocytes and expression of thy-1 in human choroidal neovascularization membranes (CNV) secondary to age-related macular degeneration (AMD). METHODS Retrospective review of an interventional(More)
