Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 871-878, May 2026.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.

A Novel Perspective on Multiple Sclerosis: Morphological Shifts in Immune Cell Populations

open access: yesProgress in Neurology and Psychiatry, Volume 30, Issue 2, May 2026.
ABSTRACT This study aims to investigate expanded hematological data in multiple sclerosis (MS) and evaluate their association with disease severity. A total of 190 patients participated in the study. For this purpose, expanded hemocytometry data were compared between 120 patients diagnosed with MS and 70 healthy controls.

Aspect Asymmetry in Martian Gullies: A Topographic Signature of Their Formation Process?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract On Mars, erosional‐depositional landforms named gullies provide natural experiments for studying the topographic signature of the processes that act on hillslope evolution. High‐resolution topographic data were used to quantitatively compare the steepness of opposing walls in gully alcoves incised into ice‐rich slopeside mantling deposits.

Control Strategies in Guanine Biocrystallization

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Additional Crypt Phenotypes Lined With High‐Grade Cellular Dysplasia in Protruding Growths in Ulcerative Colitis

open access: yesAPMIS, Volume 134, Issue 5, May 2026.
ABSTRACT Two crypt phenotypes (ACP): crypt rings in tandem (CRT) and crypts with lateral budding's (CLB's) were recently found interpolated amidst generally accepted crypt phenotypes (GACP, i.e., tubular, tubulovillous, villous and serrated). The frequency of cases with UC‐PDG, with CRT and with CLB's in GACP and in UC‐associated sporadic adenomas (UC ...
