Abstract: A system and method for radiochromic film calibration utilizing non-ionizing radiation to achieve controlled and reproducible exposures without the need for ionizing radiation sources or specialized expertise. The system includes a non-ionizing photon source, such as LEDs or laser diodes, emitting ultraviolet or visible light, a mechanical shutter to control exposure duration, and a control unit regulating light emission and shutter operation. A variable optical element of a collimator can be used to shape and direct the light beam for uniform exposure. Precise calibration of the system is performed through a field radiometer for routine verification and periodic cross-validation with ionizing radiation sources.

Abstract: The present invention relates to compounds that exhibit vasodilatory and anti-inflammatory effects by inhibiting the activity of soluble epoxide hydrolase (sEH). The present invention is also directed to methods of identifying such compounds, and use of such compounds for the treatment of diseases related to dysfunction of vasodilation, inflammation, and/or endothelial cells. In particular non-limiting embodiments, components of the invention may be used to treat hypertension.
