Background/aim: A mobile system allowing hospital medical personnel to prepare for the administration of radiation mitigators prior to receiving casualties is desirable.
Materials And Methods: We evaluated a portable spectroscopic personal radiation detector for use as an ambulance-based unit for early detection and identification of gamma radiation. We tested the sensitivity, time-to-identification, and radionuclide identification accuracy rates, change in detector response to vehicle operation, interference from cardiac equipment, and internal versus external radiation source location.
Results: We detected radiation sources in each of 119 trials using a humanoid phantom in a moving ambulance with a primary radionuclide identification accuracy of 96%. Typical identification time was around two minutes (149±95 s).
Conclusion: Our observations suggest this mobile system is a potential pre-hospital arrival tool allowing for rapid preparation of radiation mitigators.

Urethra-sparing prostate cancer radiotherapy: Current practices and future insights from an international survey.

Purpose: In prostate cancer patients, high radiation doses to the urethra have been associated with an increased risk of severe genitourinary toxicity following dose-escalated radiotherapy. Urethra-sparing techniques have emerged as a promising approach to reduce urinary toxicity. This international survey aims to evaluate current global practices in urethra-sparing and explore future directions for the implementation of this technique in external beam radiotherapy (EBRT) for prostate cancer.

Gliclazide (GLZ), an oral antihyperglycemic medication, has additional beneficial effects, such as anti-inflammatory and antioxidant properties, besides lowering blood glucose levels. In this study, the radio-protective effect of GLZ was evaluated against ionizing radiation (IR)-induced intestinal injury in mice. Eight groups of mice were randomized as follows: control, GLZ (5, 10, and 25 mg/kg), IR (6 Gy), and IR + GLZ (at 5, 10, and 25 mg/kg).

Radiotherapy stands as a cornerstone in cancer therapy, with nuclear DNA acknowledged as the principal target molecule for radiation-induced cellular demise or injury. Nonetheless, an expanding body of contemporary research elucidates the significant contri-bution of sphingolipids to radiation-induced cell death, particularly in modulating radiation-induced apoptosis. Radiation can instigate apoptosis through multiple pathways of sphin-golipid metabolism, encompassing the activation of ceramide synthase, acid sphingomyelin-ase, neutral sphingomyelinase, sphingosine-1-phosphate lyase, and sphingosine-1-phosphate phosphatase, and the inhibition of sphingosine kinase-1.

Background: With increasing evidence supporting three-dimensional (3D) automated breast (AB) ultrasound (US) for supplemental screening of breast cancer in increased-risk populations, including those with dense breasts and in limited-resource settings, there is an interest in developing more robust, cost-effective, and high-resolution 3DUS imaging techniques. Compared with specialized ABUS systems, our previously developed point-of-care 3D ABUS system addresses these needs and is compatible with any conventional US transducer, which offers a cost-effective solution and improved availability in clinical practice. While conventional US transducers have high in-plane resolution (axial and lateral), their out-of-plane resolution is constrained by the poor intrinsic elevational US resolution.

The long-term stability of Pt-based catalysts is critical to the reliability of proton exchange membrane fuel cells (PEMFCs), and receives constant attention. However, the current knowledge of Pt oxidation is restricted to unrealistic PEMFC cathode environment or operation, which questions its practical relevance. Herein, Pt oxidation is investigated directly in a PEMFC with stroboscopic operando high energy X-ray scattering.
