Liver metastases from colorectal cancer (CRC) result in substantial morbidity and mortality. The primary treatment is systemic chemotherapy, and in selected patients, surgical resection; however, for patients who are not surgical candidates and/or fail systemic chemotherapy, liver-directed therapies are increasingly being utilized. Yttrium-90 (Y-90) microsphere therapy, also known as selective ...
Yttrium-90 microsphere brachytherapy of the liver exploits the distinctive features of the liver anatomy to treat liver malignancies with beta radiation and is gaining more wide spread clinical use. This report provides a general overview of microsphere liver brachytherapy and assists the treatment team in creating local treatment practices to provide safe and efficient patient treatment. Sugge...
A new method of preparing ionically cross-linked polyphosphazene hydrogel microspheres which enables effective control over microsphere size distribution has been developed. The synthesized microspheres can be used in protein delivery and, especially, as vaccine delivery vehicles. A new technique utilizes the ability of aqueous solutions of poly[di(carboxylatophenoxy)phosphazene] (PCPP) to form...
OBJECTIVE To study the degradation and basic fibroblast growth factor (bFGF) release activity of bFGF - poly(lactic-co-glycolic-acid) microsphere (bFGF-PLGA MS) under stress in vitro, including the static pressure and shearing force-simulating mechanical environment of the joint cavity. METHOD First, bFGF-PLGA MSs were created. Meanwhile, two self-made experimental instruments (static pressur...
Abstract A fiber-optic temperature sensor based on fiber tip polystyrene microsphere is proposed. The structure can be formed simply by placing and fixing a the center of an optical tip. Since has much larger thermal expansivity, used for high-sensitive measurement. By illuminating with broadband light source through Fabry-Perot interference between front back surfaces microsphere, phase differ...
