Abstract: The present invention provides radiosensitizer compositions, in controlled-release formulations or other acceptable formulations, particularly nitrohistidine radiosensitizer compositions, which may be administered by any suitable means including oral, intravenous, arterial infusion, intraperitoneal, intramuscular, subcutaneous, surgical, and topical. Optionally, radiosensitizer compositions may be formulated with other agents, including chemotherapy agents and agents that provide a synergistic radiosensitizing effect. Methods of potentiating radiotherapy cancer treatment of cancers in humans, particularly of astrocytomas, are also presented, wherein a radiosensitizer composition is administered and radiotherapy is directed to the site of the tumor. Chemotherapy regimens may also be used as adjuvant therapy.

Abstract: An air powered sprayer for dispensing material slurries such as stucco or texturing on substrate such as drywall. The sprayer includes a canister assembly within which a piston assembly is adapted to reside and reciprocate along the length of the canister. An air inlet is disposed at one end of the piston canister assembly, and at an opposite end, a slurry inlet and outlet device is provided. Upstream from the slurry outlet there is a nozzle assembly which allows the through passage of the slurry material for subsequent combination with air at a nozzle assembly for broadcasting on the surface to be treated.
