Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome

open access: yesThe FEBS Journal, EarlyView.
Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

open access: yesJournal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Isolated in the highlands, found in the museum: A new species of Characidium (Crenuchidae) from a Bolivian National Park, with a CT scan revealing features

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from a small, isolated river in the highland areas of Noel Kempff Mercado National Park, Bolivia. The new taxon can be diagnosed by the presence of a relatively broad and conspicuous dark midlateral stripe extending from the tip of snout to the base of the caudal fin, markedly darker than the vertical ...

Application of Noise2Inverse and adaptation (Noise2Phase) to single‐mask x‐ray phase contrast micro‐computed tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract X‐ray phase contrast imaging (XPCI), when implemented in micro‐computed tomography (micro‐CT) mode, offers high‐contrast 3D imaging of weakly‐attenuating material samples. In the so‐called single‐mask edge illumination approach, a mask with periodically spaced transmitting apertures is used to split the x‐ray beam into narrow beamlets; when ...
