Methoxsalen-induced macular toxicity

Indian Journal of Ophthalmology, 2017
Psoralen compounds such as methoxsalen are photosensitizer agents used in conjunction with ultraviolet A (UVA) radiation exposure as photochemotherapy (Psoralens and ultraviolet-A therapy [PUVA therapy]) for certain epidermal skin disorders such as ...

Senescent Cell Derived Artificial Vesicle‐Based Senolytic Sonovaccine Platform with Augmented Lymph Node Delivery and Antigen Cross‐Presentation Efficacy

Advanced Science, EarlyView.
A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

Topical Administration of Tetrasodium-Mesotetraphenyl-Porphinesulfonate (TPPS) and Red Light Irradiation for the Treatment of Superficial Neoplastic Lesions

, 1987
In photodynamic therapy, systemic administration of photosensitizing agents induces cutaneous photosensitization in patients. This side-effect can be avoided by topical administration of the agents when only surface lesions are involved.

A Multicenter Phase II Study on Photodynamic Therapy Using Talaporfin Sodium (ME2906) and a Semiconductor Laser (PNL6405CIN) for Intraepithelial Tumors of the Cervix

Reproductive Medicine and Biology
Purpose Conization for high‐grade cervical intraepithelial neoplasia (CIN2–3) often harms obstetric outcomes. Photodynamic therapy (PDT) with talaporfin sodium provides a cervix‐sparing alternative with short photosensitivity.

A Deep‐Red‐Absorbing Osmium(II) Complex as a Photosensitizer for Photodynamic Therapy Inducing Immunogenic Cell Death

Angewandte Chemie, EarlyView.
A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

AI‐Assisted Digital Single‐Molecule Activity Tracker for Decoupling Intrinsic Heterogeneity from Photo‐Oxidative Damage in High‐Photon‐Flux Enzymology

Advanced Science, EarlyView.
Employing a digital single‐molecule activity tracker (dSMAT), this research demonstrates that high‐photon‐flux irradiation drives progressive oxidative scarring in polymerases. Unlike simple thermal denaturation, real‐time kinetic tracking dynamically visualizes enzymes degrading into multiple impaired subpopulations.
