Photosensitizers-Loaded Nanocarriers for Enhancement of Photodynamic Therapy in Melanoma Treatment
Pharmaceutics, 2023 Malignant melanoma poses a significant global health burden. It is the most aggressive and lethal form of skin cancer, attributed to various risk factors such as UV radiation exposure, genetic modifications, chemical carcinogens, immunosuppression, and ...

Asymmetric Oxidation of Giant Vesicles triggers Curvature-associated Shape Transition and Permeabilization. Running title: Oxidation of Vesicles produces Curvature [PDF]
Biophysical Journal, Biophysical Society, 2009, 97 (11),
pp.2904-2912, 2019 (200 words) Oxidation of unsaturated lipids is a fundamental process involved in cell bioenergetics as well as in cell death. Using giant unilamellar vesicles and a chlorin photosensitizer, we asymmetrically oxidized the outer or inner monolayers of lipid membranes.

Charge order in photosensitive Bi0.4Ca0.6MnO3 films [PDF]
, 2005 We report structural and electronic characterization of the charge order phase in Bi0.4Ca0.6MnO3 films, in which photoinduced resistivity changes have been observed at temperatures approaching room temperature. In all films, lattice distortions associated with the charge order are observed, and both the wavevectors and displacements of the distortions ...

Effect of light intensity on resonance patterns in CDIMA reaction [PDF]
arXiv, 2021 Photosensitive CDIMA reaction-diffusion equation is considered to explain the resonance in the linearly coupled system. The conditions for Turing instability is obtained for the coupled reaction-diffusion system. Also, determining the critical diffusion coefficients for exiting the resonance type pattern is also discussed with analytical conditions ...

Analysis of Biomedical Signals by Flicker-Noise Spectroscopy: Identification of Photosensitive Epilepsy using Magnetoencephalograms [PDF]
Laser Physics (2009) 19(4): 836-854, 2008 The flicker-noise spectroscopy (FNS) approach is used to determine the dynamic characteristics of neuromagnetic responses by analyzing the magnetoencephalographic (MEG) signals recorded as the response of a group of control human subjects and a patient with photosensitive epilepsy (PSE) to equiluminant flickering stimuli of different color combinations.

Photodynamic therapy as a new therapeutic approach of oral lichen planus [PDF]
, 2019 Oral lichen planus (OLP) is a chronic, immunologically mediated disease, defined by periods of exacerbation and quiescence. The disease is associated with a low mortality risk, but in some instances, morbidity can be important, especially in extensive ...

Transscleral diode photocoagulation of large retinal and choroidal vascular lesions. [PDF]
PLoS ONE, 2012 BACKGROUND: Transscleral retinal photocoagulation with a diode laser is used in glaucoma refractory to medical and surgical treatment. Our main research question was how the technique performed in large vascular lesions associated with hemangiomas of the

Laser-induced instabilities in liquid crystal cells with a photosensitive substrate [PDF]
, 2014 Liquid crystal layers sandwiched between a reference plate and a photosensitive substrate were investigated. We focused on the reverse geometry, where the cell was illuminated by a laser beam from the reference side. In planar cells instabilities occurred, static and dynamic ones, depending on the angle between the laser polarization and the director ...
