Pyrazinamide-induced phototoxicity: A case report and review of literature

Indian Journal of Dermatology, 2010
A 40-year-old male presented with a fresh case of pulmonary tuberculosis and itchy oozing rashes distributed characteristically over the sun exposed areas of the skin. These rashes had developed since six days following 10 days of start of antitubercular

Self‐Sustaining Lactate Depletion Nanoplatform Remodels Tumor Microenvironment and Augments Synergistic Photodynamic/Photothermal/Chemodynamic/Starvation Therapy for Eradication of Colon Cancer

Advanced Science, EarlyView.
The HILA nanoplatform integrates HMnO2, LOX, and ICG to orchestrate multimodal therapy (starvation, chemodynamic, photodynamic, and photothermal) for achieving efficient colon cancer eradication. The established HMnO2‐LOX catalytic cycle continuously consumes lactate, acidifys microenvironment, relieves hypoxia, and generats reactive oxygen species ...

Photoaugmentation in Drug Phototoxicity

Journal 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.

Longitudinal Single‐Axon‐Resolution Imaging of Peripheral Nerve Injury Response in Mice Using an Optical Window Implant

Advanced Science, EarlyView.
A minimally invasive optical window enables stable, long‐term imaging of peripheral nerves in vivo at single‐axon resolution. Dynamic processes of degeneration, regeneration, and cellular remodeling are visualized across multiple time scales within the same nerve region, providing a unique platform to study a variety of anatomical and molecular events ...

The Study on Timolol and Its Potential Phototoxicity Using Chemical, In Silico and In Vitro Methods

Pharmaceuticals
Timolol (TIM) is a non-selective ß-adrenergic receptor antagonist used orally for the treatment of hypertension and heart attacks, and topically for treating glaucoma; lately, it has also been used in some specific dermatological problems. In the present

Engineering Synergistic Intra‐/Intermolecular Conformational Locking via Side‐Chain Branching: A β‐Sheet‐Inspired Strategy for Planar NIR‐II Phototheranostic Aggregates

Advanced Science, EarlyView.
A bio‐inspired side‐chain branching strategy is developed to orchestrate a dual noncovalent conformational locking (NoCL) network, enabling the construction of perfectly planar NIR‐II phototheranostic aggregates. Such structural precision maximizes light‐harvesting efficiency and optimizes exciton dynamics, ensuring synchronized enhancements in NIR‐II ...

Mechanism of Tetracycline Phototoxicity

Journal of Investigative Dermatology, 1984
Studies were made to determine factors important in the phototoxicity mechanism of 7 clinically used tetracyclines (TC). The clinical phototoxicity, the rates of photochemical degradation, and the in vitro phototoxicity of the TCs were qualitatively but not quantitatively correlated.
