3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, EarlyView.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Outcomes of Focused Double Extrastimuli Mapping and Ablation in Ventricular Tachycardia

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Conventional substrate mapping for scar‐related ventricular tachycardia (VT) often fails to fully delineate critical arrhythmogenic components. Functional mapping strategies using extrastimuli have shown promise but are limited by procedural complexity.

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Mycelial dynamics in arbuscular mycorrhizal fungi

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF), similar to other filamentous fungi, develop extensive hyphal networks collectively known as mycelia. AMF mycelia are complemented by a variety of specialized structures such as spores, vesicles, and auxiliary cells, which together form integrated and functionally diverse AMF networks.

Predicting patient‐reported quality of vision through multifocal optics

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To explore the agreement between computationally modelled point‐spread functions (PSFs) and multifocal soft contact lens wearers' descriptions of image quality. Methods In Phase 1, participants were fitted with a single vision soft contact lens (SCL) in the left eye, and four different multifocal (MF) SCLs in the right eye in ...
