Vascular Endothelial Growth Factor Concentrations in Dogs with Spirocercosis [PDF]

Journal of Veterinary Internal Medicine, 2013
BackgroundVascular endothelial growth factor (VEGF) is a potent proangiogenic factor associated with tumor development. Spirocerca lupi is a nematode of canids that induces an esophageal nodule that progresses to a sarcoma in 25% of cases. Determination of neoplastic transformation is challenging and usually based on endoscopy‐guided biopsies under ...

Concentrated Growth Factor Matrices Prepared Using Silica-Coated Plastic Tubes Are Distinguishable From Those Prepared Using Glass Tubes in Platelet Distribution: Application of a Novel Near-Infrared Imaging-Based, Quantitative Technique

Frontiers in Bioengineering and Biotechnology, 2020
Platelet-rich fibrin (PRF) matrices were originally prepared using plain glass tubes without the aid of coagulation factors because coagulation factor XII is activated by glass surfaces. Recently, the use of silica-coated plastic tubes as a substitute of

ROLE OF GROWTH HORMONE ON PLASMA EPIDERMAL GROWTH FACTOR CONCENTRATIONS [PDF]

Pediatric Research, 1987
Epidermal growth factor (EGF) is known to accelerate proliferation and differentiation of multiple cell types. We previously reported that growth hormone deficient (GHD) children have decreased urinary EGF excretion compared to normal children and the excretion of EGF increases with growth hormone (GH) administration.
