Swiss Practice Recommendations for Chronic Prurigo Including Prurigo Nodularis

open access: yesInternational Journal of Dermatology, EarlyView.
Chronic prurigo, including prurigo nodularis, is a chronic, often treatment‐refractory condition characterized by persistent pruritus and chronic scratch lesions. Advances in the understanding of its underlying pathophysiology have enabled the development of novel targeted therapies; however, management remains challenging due to the expanding range of

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Spectroscopic analysis of bacterial photoreactivation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Depth of DNA photodamage in human corneas exposed to 222 nm or 254 nm UV

open access: yesPhotochemistry and Photobiology, EarlyView.
Representative confocal 3D image of a section of a human cornea showing nuclei in blue (Hoechst 33342) and green, which was assigned to cells exhibiting Alexa555 conjugated to anti‐CPD antibody. The depth of photodamage was measured in Z‐stacks of the human corneal epithelium after exposure of the anterior surface to 50 or 100 mJ/cm2 at 222 or 254 nm ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

open access: yesPhotochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

open access: yesSedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 3, Page 677-700, September 2026.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.
