While radiotherapy (RT) is commonly used in clinics for cancer treatment, the therapeutic efficiency is not satisfactory owing to the existence of the hypoxic tumor microenvironment which seriously affects the efficiency of RT. Herein, we design polyethylene glycol (PEG)-modified reduced nano-graphene oxide-manganese dioxide (rGO-MnO2-PEG) nanocomposites to trigger oxygen generation from H2O2 t...
Unidirectional influx and efflux of nutrients and toxicants, and their resultant net fluxes, are central to the nutrition and toxicology of plants. Radioisotope tracing is a major technique used to measure such fluxes, both within plants, and between plants and their environments. Flux data obtained with radiotracer protocols can help elucidate the capacity, mechanism, regulation, and energetic...
A hydrodynamic bi-compartmental model for the cerebrospinal fluid (CSF) flow in humans is presented which combines anatomical and physiological conditions in the central nervous system with results of special radioisotope diagnostic techniques. Normal and disturbed conditions, the diagnostic methods and the results are explained. A differential equation for the time behaviour of regional radioi...
BACKGROUND The rapidly growing field of targeted tumor therapy often utilizes an antibody, sometimes tagged with a tumor-ablating material such as radioisotope, directed against a specific molecule. METHODOLOGY/PRINCIPAL FINDINGS This report describes the discovery of nine novel decapeptides which can be radioactively labeled, bind to, and deliver (32)P to colon cancer cells. The decapeptides...
