DanMAX – a beamline for materials science using powder X‐ray diffraction, total scattering, and full‐field tomographic imaging

Journal of Synchrotron Radiation, EarlyView.
The DanMAX beamline at the MAX IV laboratory is designed for in situ and in operando studies using powder X‐ray diffraction, total scattering, and full‐field imaging in the 15–35 keV energy range.DanMAX is a hard X‐ray materials science beamline at the ultra‐low emittance 3 GeV storage ring at the MAX IV laboratory.

Quantitative Dual‐Energy CT Perfusion Versus SPECT/CT V/Q Scintigraphy for Preoperative Lung Function Assessment: A Prospective Cohort Study

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Accurate preoperative physiological assessment is critical for high‐risk patients undergoing lung resection to predict postoperative lung function. This study compared quantitative dual‐energy CT (DECT) perfusion with SPECT/CT for lobar perfusion mapping in an at‐risk oncological cohort.

Photon‐Counting Detector CT Versus Conventional CT for Low‐Dose Chest Imaging: A Reader Preference Study

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Background Photon‐counting detector CT (PCD‐CT) is a technology that directly counts individual photons and their energy, compared to conventional energy‐integrating detector CT (EID‐CT) which measures the total deposited X‐ray energy without distinguishing photon energies.

Extracellular vesicles in pharmacology: Innovations in drug delivery and therapeutic applications in cancer

British Journal of Pharmacology, EarlyView.
Extracellular vesicles (EVs) are a diverse population of membrane nanoparticles secreted by nearly all cell types, playing a key role in intercellular communication by transferring bioactive macromolecular cargo. In cancer, EVs shape both the local tumour microenvironment and distant premetastatic niches.

Human iPSC‐Derived Vascularised Lung Organoids for Modelling COPD and Pulmonary Hypertension

Cell Proliferation, EarlyView.
Vascularised lung organoids (vLOs) that faithfully mimic human lung tissue architecture and disease pathology are critical for advancing pulmonary research but remain challenging to generate. Here, we developed a robust self‐organisation protocol to produce vLOs with cellular heterogeneity and functional vasculature. The engineered blood vessels within
