Sunscreen-Based Photocages for Topical Drugs: A Photophysical and Photochemical Study of A Diclofenac-Avobenzone Dyad

open access: yesMolecules, 2018
Photosensitization by drugs is a problem of increasing importance in modern life. This phenomenon occurs when a chemical substance in the skin is exposed to sunlight.

Drug phototoxicity in mice

open access: yesActa Dermato-Venereologica, 1978
A series of agents with alleged photosensitizing properties has been studied in mice by a quantitative in vivo method for acute drug phototoxicity. The method, originally developed for phenothiazine studies, was found suitable for several drug groups with varying mechanism of action, such as tetracyclines, protoporphyrin and psoralens.

Curvature‐Directed Elongation and Chiral Tilting Drive Asymmetric Tissue Patterning

open access: yesAdvanced Science, EarlyView.
Curvature and cell handedness together break tissue symmetry. On convex and concave surfaces, cells elongate along opposite geometric axes and tilt in a consistent chirality‐driven direction, yielding opposite alignment patterns from the same cells. Reversing intrinsic cell chirality reverses both.

Topical minocycline foam 4%: Results of four phase 1 studies evaluating the potential for phototoxicity, photoallergy, sensitization, and cumulative irritation

open access: yesJournal of Immunotoxicology, 2019
FMX101 4% contains 4% micronized minocycline (as an HCl) formulated in a lipophilic foam vehicle for topical administration. FMX101 4% has been shown to be an effective and well-tolerated treatment for moderate-to-severe acne in three Phase 3 pivotal ...

Developmentally Guided Differentiation of Ventral Midbrain Dopaminergic Cells Validated in Proteopathy‐Based Parkinson's Disease Models

open access: yesAdvanced Science, EarlyView.
A developmentally guided protocol reproducibly specifies EN1‐positive ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells and yields functional vmDA neurons. Optogenetic induction of α‐synuclein aggregation elicits selective degeneration of TH‐positive neurons in 2D cultures and 3D neurospheroids, while transplanted ...

Huntingtin Aggregate‐Responsive Autophagy Gene Circuit Mitigates Disease Pathology in R6/2 Mice

open access: yesAdvanced Science, EarlyView.
CD98‐mediated receptor‐mediated transcytosis enables LIP‐CD98 nanocarriers to cross the blood–brain barrier and deliver ARAA to neurons. mHTT aggregates activate the 11G–NarX sensor, initiating Auto‐P and Trans‐P signaling through the VP48–NarL relay.

Photoaugmentation in Drug Phototoxicity

open access: yesJournal of Investigative Dermatology, 1980
The phototoxic reaction to chlorpromazine and other drugs is provoked by long-wave ultraviolet light (UVA). It was shown by the in vivo mouse tail technique that the reaction is enhanced by medium-wave ultraviolet light (UVB), thus demonstrating the importance of photoaugmentation in this process.

Near‐Unity Photothermal Conversion in Bimetallic M44 and M81 Nanoclusters Enables NIR‐Driven Photo‐Thermo‐Electricity Generation

open access: yesAdvanced Science, EarlyView.
Atomically precise nanoclusters of Au/Ag alloys are explored as high‐performance photothermal materials, delivering record‐high photothermal efficiencies (up to 91%). Photo‐thermo‐electricity is further demonstrated by integrating nanocluster films with thermoelectric devices.
