Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Alloxazine derivatives as multifunctional agents for photodynamic therapy, cancer cell imaging, and cell proliferation inhibition

Photochemistry and Photobiology, EarlyView.
Alloxazine photosensitizers, molecularly engineered through sugar conjugation and methoxy substitution to enhance solubility, photodynamic potency, and fluorescence, enable image‐guided photodynamic therapy while inhibiting cancer cell growth in the absence of photoactivation.

Photodynamic inactivation increases cell death rate on persistent Staphylococcus aureus

Photochemistry and Photobiology, EarlyView.
Persistent bacteria have the ability to survive extended periods of antibiotic stress by entering a metabolically dormant state. This study investigated persistence formation in two S. aureus strains and evaluated the effects of PDI using curcumin. Post‐PDI time‐kill assays conducted after metabolic recovery showed a higher rate of bacterial death ...

Nanoengineered photosensitizers for photodynamic priming to overcome P‐glycoprotein‐mediated multidrug resistance

Photochemistry and Photobiology, EarlyView.
Verteporfin's subcellular localization governs its ability to deplete ATP. LysoPC‐conjugated VP accumulates in lysosomes and spares mitochondria, while liposomal and NanoVP formulations target mitochondria, where light activation triggers membrane depolarization and ATP depletion, overcoming resistance seen with free‐form VP. Abstract P‐glycoprotein (P‐

The role of constitutive nitric‐oxide synthase in regulation of IKKα after ultraviolet irradiation

Photochemistry and Photobiology, EarlyView.
cNOS enhances IKKα expression following UVB exposure by promoting promoter activation, transcriptional elongation, and Ets‐1 stabilization. These actions sustain IKKα levels, reduce UV‐induced skin carcinogenesis, and highlight cNOS as a key protective factor against solar UV damage.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

Advantages of horizontal centrifugation of platelet‐rich fibrin in regenerative medicine and dentistry

Periodontology 2000, EarlyView.
Abstract The aim of this comprehensive review was to evaluate comparative studies on horizontal and fixed‐angle centrifugation methods for preparing platelet‐rich fibrin (PRF). Furthermore, additional studies utilizing horizontal PRF (H‐PRF) were systematically investigated.

Singlet Fission in Push–Pull Para‐Azaquinodimethane Films under the Gaze of Time Resolved Optical and Magnetic Spectroscopy

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.
New push–pull para‐azaquinodimethane derivatives were synthetized through a sustainable protocol. Transient absorption results showed ultrafast intermolecular singlet fission (SF) in film and demonstrated for AsOMe higher triplet energy than for literature SF materials, with intriguing perspectives for photovoltaics toward silicon matched SF.
