    We performed voltage-clamp experiments on outside-out patches excised from HEK293 cells stably expressing hNav1.5. Upon 3-min exposure to a 808.5 nm laser the peak Na+ current amplitude remained steady (96.64ยฑ5.25% of initial values) while in control conditions it decreased (37.95ยฑ9.14%); in whole-cell experiments relative amplitudes were 111.2ยฑ47.0% (laser) vs. 70.6ยฑ33.0% (control). We also...

    Small accelerators are capable of delivering ultra-high dose rates (UHDR) during proton irradiation, which makes them valuable tools in the development of FLASH radiotherapy. However, achieving accurate in-air irradiation at such dose rates demands exceptionally precise beam characterization. This work describes the way we addressed the challenge of accurate dosimetry while developing a new...

    PURPOSE:
    In many institutions, tumors, and organs at risk contours are delineated manually; this is also costly and time-consuming. Recently, various automatic contouring methods have been developed to address these problems. However, these methods may not provide accurate contours for the physicians. One of the reasons is that most autocontouring algorithm results have been produced on CT...

    Purpose Gamma index analysis and equipment are the most commonly used
    methods and equipment for dosimetric control. Gamma index analysis is influenced
    by multiple factors, and its accuracy is contingent upon various parameters and
    variables. However, there has been limited research on how variations or errors in
    dose delivery impact the results of gamma analysis, especially when conducted...

    Zinc phthalocyanine (ZnPc) derivatives have many interested
    properties, such as high absorption capacity in the first
    near-infrared region, good reactive oxygen species (ROS) generation
    efficiency, and excellent photostability [1-3]. However, ZnPc are
    highly hydrophobic and tend to aggregate, which decreases their
    photosensitivity. Therefore, many attempts have been...
