Extracellular Matrix Remodeling in Actinic Cheilitis and Lip Squamous Cell Carcinoma: A Cross‐Sectional Study

Oral Diseases, EarlyView.
ABSTRACT Background Actinic cheilitis is a precursor to lip squamous cell carcinoma. How ultraviolet‐induced stromal degeneration relates to invasion‐related extracellular matrix markers remains unclear. This study investigated basophilic degeneration of collagen, solar elastosis, fibronectin, tenascin‐C, and podoplanin in both lesions.

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Chlorophyll a Fluorescence Kinetics Reveal That Ozone Stress Redistributes Electron Transport Limitations Between PSII and PSI in Wheat

Plant, Cell &Environment, EarlyView.
ABSTRACT Tropospheric ozone (O3) reduces crop productivity, but the sites at which ozone alters photosynthetic electron transport remain unclear. We tested whether acute exposure to O3 shifts the dominant site of electron transport limitation in a cultivar‐specific manner, rather than causing a uniform decline in PSII function.

Inhibition of P‐glycoprotein using photoimmunotherapy in peritoneal metastasis mouse model

Photochemistry and Photobiology, EarlyView.
Photoimmunotherapy (PIT) using photoimmunoconjugates (PICs) can inhibit the function of the ATP‐binding cassette (ABC) transporter P‐glycoprotein (P‐gp) in a mouse model of peritoneal carcinomatosis. Sterile‐filtered PIC was administered in vivo via intraperitoneal (IP) injection 20 days after IP tumor cell implantation of P‐gp‐overexpressing NCI/ADR ...

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

Photochemistry 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 ...

Understanding exosomes in facial esthetics and skin aging

Periodontology 2000, EarlyView.
Abstract Background Skin aging is a multifactorial process mediated by intrinsic (genetic and metabolic) and extrinsic (environmental) factors leading to functional and structural deterioration, including wrinkles, loss of collagen and elastin, as well as various pigmentation disorders.

Expanding the Energetic Limits of Photosynthesis for Broad‐Spectrum Plant Design: Insights From Far‐Red Photosystem I

Modern Agriculture, Volume 4, Issue 2, December 2026.
Consoli et al. mapped eight Chl f‐binding sites in far‐red‐light‐acclimated photosystem I (FR PSI). Structural and spectroscopic evidence supports the involvement of Chl f at the A−1B site in primary charge separation and indicates that its protein microenvironment modulates redox properties.

A Physical Organic Odyssey: From the Ultrafast Dynamics of Carbenes and Nitrenes to Contemporary Chemical Biology and Drug Discovery

Journal of Physical Organic Chemistry, Volume 39, Issue 9, September 2026.
Physical organic chemistry transforms photoaffinity labeling from empirical photochemistry into rational probe design. By measuring reactive‐intermediate lifetimes, pathways, and selectivity, Platz's legacy connects carbene and nitrene mechanisms to modern chemoproteomics, enabling more precise protein labeling and drug‐discovery maps.
