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

open access: yesPhotochemistry 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.

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

open access: yesPhotochemistry and Photobiology, EarlyView.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa

Direct evidence of singlet molecular oxygen [O2 (1Δg)] production from UVA excited 6‐thioguanine

open access: yesPhotochemistry and Photobiology, EarlyView.
6‐Thioguanine (6‐TGua) is incorporated into DNA as a purine analogue, inhibiting cell replication. Patients treated with 6‐TGua are more prone to developing skin cancer due to the photoexcitation of 6‐TGua by UVA radiation (as illustrated in the Jablonski diagram). Upon exposure to UVA, the excited 6‐TGua generates 1O2.

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

open access: yesPeriodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.

Antimicrobial Effect of Ultraviolet C (UV‐C) Light Compared to Standard Povidone‐Iodine Protocol for Preoperative Disinfection of the Periocular Area

open access: yesVeterinary Ophthalmology, EarlyView.
ABSTRACT Objective To evaluate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on the periocular area of canine eyes for preoperative disinfection compared to standard 10% povidone‐iodine (PI) solution preparation. Methods The upper and lower eyelids of six research‐bred beagles were equally divided into two sections (medial ...
