摘要:
A Cherenkov imaging system for determining surface radiation dose for a subject undergoing radiation therapy includes (a) a first camera for capturing a Cherenkov image of Cherenkov radiation from a surface region of the subject undergoing Cherenkov-radiation-inducing radiation therapy, (b) a second camera for capturing a reflectance image of reflectance of optical illumination off the surface region, and (c) a correction module for correcting the Cherenkov image based upon the reflectance image to form a corrected Cherenkov image that indicates radiation dose for the surface region. A Cherenkov imaging method for determining surface radiation dose for a subject, undergoing radiation therapy includes correcting a Cherenkov image, of Cherenkov radiation from a surface region of the subject undergoing Cherenkov-radiation-inducing radiation therapy, using a reflectance image of visible light reflected by the surface region, to form a corrected Cherenkov image that indicates radiation dose for the surface region.
摘要:
A system and method for converting biomass with no substantial pretreatment is disclosed. Combination of a microbial system and the use of mechanical disruption may help achieve high conversion rate without the extra cost and undesirable by-products typically associated with the pretreatment process.

Systems and methods for pulse electrothermal and heat-storage ice detachment. A pulse electrothermal ice detachment apparatus includes one or more coolant tubes, and optionally, fins in thermal contact with the coolant tubes. The tubes and/or fins form a resistive heater. Apparatus applies electrical power to the resistive heater, generating heat to detach ice from the tubes and/or the fins. A freezer unit forms a heat-storage icemaking system having a compressor and a condenser for dissipating waste heat, and coolant that circulates through the compressor, the condenser and a coolant tube. The coolant tube is in thermal contact with an evaporator plate. A tank, after the compressor and before the condenser, transfers heat from the coolant to a heating liquid. The heating liquid periodically flows through a heating tube in thermal contact with the evaporator plate, detaching ice from the evaporator plate.

Methods of utilizing reduced cellulase loads to hydrolyze cellulosic substrates are disclosed. The methods include determining an amount of purified cellulase necessary to substantially hydrolyze a quantity of cellulosic substrate in a period of time; reducing the amount of purified cellulase by a factor of between 2 and 5 to determine a reduced cellulase load; and introducing to the cellulosic substrate either (1 ) a microorganism expressing cell-bound cellulase in a concentration equal to the reduced cellulase load or (2) a fermentation agent that has been engineered to express cell-bound cellulase in a concentration equal to the reduced cellulase load under suitable conditions and for said period of time sufficient to allow substantial hydrolysis of the cellulosic substrate.

Methods for inducing T cell tolerance to a tissue or organ graft in a transplant recipient are disclosed. The methods involve administering to a subject: 1) an allogeneic cell which expresses donor antigens and which has a ligand on the cell surface which interacts with a receptor on the surface of a recipient T cell which mediates contact-dependent helper effector function; and 2) an antagonist of the receptor which inhibits interaction of the ligand with the receptor. In a preferred embodiment, the allogeneic or xenogeneic cell is a B cell, preferably a resting B cell, and the molecule on the surface of the T cell which mediates contact-dependent helper effector function is gp39. A preferred gp39 antagonist is an anti-gp39 antibody. The allogeneic or xenogeneic cell and the gp39 antagonist are typically administered to a transplant recipient prior to transplantation of the tissue or organ. The methods of the invention can be used to induce T cell tolerance to transplants such as liver, kidney, heart, lung, skin, muscle, neuronal tissue, stomach and intestine. A method for treating diabetes comprising administering to a subject allogeneic or xenogeneic cells expressing donor antigens, a gp39 antagonist and pancreatic islets is also disclosed.
