Contrast-induced nephropathy (CIN) is a leading cause of morbidity and mortality in high-risk patients undergoing percutaneous coronary intervention (PCI) or other radiocontrast procedures. Approximately 25% of all patients selected for these procedures are at risk for its development. Patients who experience this complication have higher rates of mortality, longer hospital stays and poorer lon...
BACKGROUND Although a variety of therapeutic approaches are available for the treatment of Parkinson's disease, challenges limit effective therapy. Among these challenges are delivery of drugs through the blood brain barier to the target brain tissue and the side effects observed during long term administration of antiparkinsonian drugs. The use of drug delivery systems such as liposomes, nioso...
BACKGROUND Radiocontrast nephropathy (RCN) is one of the leading causes of hospital-acquired acute renal insufficiency. Adenosine, a renal vasoconstrictor, is thought to play a role in RCN. In this study, aminophylline, a non-selective adenosine-competitive inhibitor, was evaluated as a potential agent to protect against RCN. METHODS Twenty-six patients treated with 200 mg intravenous aminoph...
X-ray imaging optimization of 3D tissue engineering scaffolds via combinatorial fabrication methods.
We have developed a combinatorial method for determining optimum tissue scaffold composition for several X-ray imaging techniques. X-ray radiography and X-ray microcomputed tomography enable non-invasive imaging of implants in vivo and in vitro. However, highly porous polymeric scaffolds do not always possess sufficient X-ray contrast and are therefore difficult to image with X-ray-based techni...
