Summary: A real-time in vivo cancer detection method using attenuation-based plain X-ray imaging is proposed, successfully detecting 5 mm-sized Panc-1 cell tumors in mice. Quantum dot scintillators of CPB are used as markers, showing significant X-ray attenuation effects for clear signal observation under 2 cm-thick tissue.

Summary: The aim of the study was to develop an experimental system that allowed the application of iodinated contrast media to intact plant roots in soil and was compatible with time-resolved synchrotron X-ray computed tomography imaging. By using synchrotron X-ray computed tomography and synchrotron X-ray fluorescence mapping, the system was successful in visualizing the translocation of contrast media through root vasculature into the leaves, providing insights into internal fluid transport mechanisms and anatomical features of the plants.

Summary: Phosphorus is essential for plant growth, and arbuscular mycorrhizal fungi (AMF) play a role in its uptake. This study used synchrotron X-ray technology to investigate AMF colonization and phosphorus uptake. The results showed that AMF co-located with high phosphorus and low aluminum areas and preferred organic-type phosphorus species. By modeling, the estimated phosphorus uptake rate by AMF hyphae was an order of magnitude lower than previously estimated.

Summary: This study aims to develop methods to reduce the impact of synchrotron X-ray radiation on root growth during in vivo imaging. The results suggest that monochromatic radiation at the highest suitable energy and controlling the rotation axis of off-centered roots can diminish radiation dose during in vivo imaging of plant roots.

Summary: This study used in operando X-ray micro-computed tomography (mu CT) to monitor the progression of the liquid, gaseous, and solid phases of silica gels during ambient pressure drying and spring-back. The findings challenge the common assumption about the penetration of gas during the spring-back effect and show that the emergence of the spring-back effect is correlated to an equal volume fraction of solid, liquid, and gas in the gels.

Summary: Photon-counting detector (PCD) CT is a novel imaging modality that changes the way CT systems detect X-rays. After clinical investigations, the first commercial PCD CT system was approved by the U.S. FDA in 2021 for clinical use. PCD CT has technological features that are well suited for musculoskeletal imaging applications.

Summary: This study examined structural changes in subchondral bone samples from osteoarthritic knee patients compared to controlled patients, using Synchrotron-based X-ray fluorescence and X-ray absorption spectroscopy techniques. The results revealed lower phosphorus content in older OA patients, leading to lower Ca-P proportions associated with osteoporosis. The majority of bone samples exhibited an amorphous structure of calcium-phosphate.

Summary: The presented overview discusses the luminescence properties of lanthanide ions in various dielectric crystalline materials for photonics and optoelectronics. Different crystals with distinct crystal structures were chosen, and the behavior of erbium ions was studied and compared. Theoretical simulations were also conducted to better understand the incorporation of erbium in these crystals.

Summary: Producing a high release speed is crucial in throwing sports, and athletes may achieve this by improving the effectiveness of the kinetic chain. Increasing upper arm mass initially boosts release speed, but the optimal upper arm mass for maximum speed is much higher than average. To enhance throwing speed, athletes can consider adding weights to the upper arm or focusing on training for mass tapering along the arm length.

Summary: The study aimed to establish a comprehensive model of injury prevention and risk factors in musicians, based on literature and interviews with experts. Findings showed that 80% of musicians from the Royal Liverpool Philharmonic Orchestra had experienced PRMDs, with postural and workload issues being the most common risk factors identified. Experts broadly agreed with the initial model and provided additional insights for assessing musicians' health.

Summary: Plain step surface decor reduces anxiety and increases foot clearances in young and higher ability older adults, while patterned decor slows descent, increases margins of stability, and reduces steps looked ahead in all ages and abilities. Step-edge highlighters increase confidence and reduce anxiety, while also increasing foot clearance in younger and higher ability older adults. Older adults with lower ability show no adaptation to step-surface visual properties.

Summary: Children who idiopathically toe-walk habitually exhibit shorter muscle-tendon unit (MTU) lengths, longer muscle belly and fascicle lengths, and shorter Achilles tendon lengths compared to typically developing children. There were no significant differences in passive lengthening properties between the two groups, but passive joint stiffness was greater in toe-walking children at specific positions. Findings suggest a remodeling of the relative MTU in toe-walking children, pointing towards a need for targeted interventions focused on the Achilles tendon.
