Abstract: A Cherenkov-based or thin-sheet scintillator-based imaging system uses a radio-optical triggering unit (RTU) that detects scattered radiation in a fast-response scintillator to detect pulses of radiation to permit capture of Cherenkov-light or scintillator-light images during pulses of radiation and background images at times when pulses of radiation are not present without need for electrical interface to the accelerator that provides the pulses of radiation. The Cherenkov images are corrected by background subtraction and used for purposes including optimization of treatment, commissioning, routine quality auditing, R&D, and manufacture. The radio-optical triggering unit employs high-speed, highly sensitive radio-optical sensing to generate a digital timing signal which is synchronous with the treatment beam for use in triggering Cherenkov light or scintillator light imaging.

Abstract: A system for dosimetry includes a radiation source that provides a pulsed radiation beam to a treatment zone, and a thin sheet of scintillator disposed between the radiation source and skin of a subject in the treatment zone. A gated camera images the scintillator integrating light from the scintillator during multiple pulses of the radiation beam while excluding light received between pulses of the pulsed radiation beam; and an image capture and processing machine that receives images from the gated camera and performs additional corrections to provide a map of dose received by the subject.

Abstract: The present disclosure provides a method of increasing an immune response in an individual, the method involving administering to an individual in need thereof an inhibitor of SIRT1. The present disclosure provides a method of reducing an immune response, e.g., to treat chronic immune hyperactivity, the method generally involving administering to an individual in need thereof an activator of SIRT1. The present disclosure provides a method of modulating activation and differentiation of CD4+ T cells.

Abstract: The present invention provides methods for reducing the level of amyloid beta protein in a cell or tissue, the methods generally involving contacting the cell or tissue with an agent that reduces cystatin C levels and/or activity. The present invention provides methods for treating Alzheimer's disease (AD), and methods for treating cerebral angiopathy, in an individual, the methods generally involving administering to an individual having AD a therapeutically effective amount of an agent that reduces cystatin C levels and/or activity. The present invention further provides methods for identifying an agent that reduces cystatin C levels and/or activity.

Abstract: The present disclosure provides methods for treating neurological disorders, generally involving modulating protein kinase D1 (PKD1) activity levels in a neuron or glial cell in an individual in need thereof. The present disclosure provides antibodies specific for PKD1. The present disclosure provides a genetically modified non-human mammal deficient in PKD1 activity.

Abstract: In a preferred embodiment, an environmentally insensitive electric detonator system for demolition, including: an object to be demolished; a main explosive charge in proximity to the object to be demolished; electrically activated detonator apparatus including a relatively insensitive initiating charge in proximity to the main explosive charge; and circuitry having input apparatus to receive an input firing pulse and having output apparatus to provide, through arbitrarily long wires, a high voltage in response thereto across the electrically activated detonator apparatus to cause ignition of the main explosive charge.
