Clinical Characteristics of Photodermatoses in Indian Patients and their Phototesting Findings: A Cross-sectional Study [PDF]
Journal of Clinical and Diagnostic Research, 2023 Introduction: Phototesting helps to confirm photosensitivity, identify the action spectra, reproduce lesions by photo provocation for biopsy, calculate starting dose of desensitisation therapy, assess the severity of the photodermatoses, and monitor ...

A protective Langerhans cell–keratinocyte axis that is dysfunctional in photosensitivity
Science Translational Medicine, 2018 Langerhans cells limit ultraviolet radiation–induced keratinocyte apoptosis and skin injury, and this axis is dysfunctional in lupus photosensitivity. Abrogating keratinocyte apoptosis in lupus Lupus patients can experience photosensitivity as manifested

Pediatric photosensitivity [PDF]
Photodermatology, Photoimmunology & Photomedicine, 2012 SummaryPhotosensitivity is a rarely encountered problem in the pediatric population. It may be caused by a diverse group of primary, idiopathic photosensitivity conditions, or may reflect photoexacerbation of an existing dermatosis. In addition, there are several genodermatoses, metabolic disorders, and connective tissue disorders that can present with

Numerical simulation of neutron radiation effects in avalanche photodiodes [PDF]
, 2000 A new one-dimensional (1-D) device model developed for the simulation of neutron radiation effects in silicon avalanche photodiodes is described. The model uses a finite difference technique to solve the time-independent semiconductor equations across a ...

Electroluminescence and photosensitivity spectra of organic diode structures based on zinc complexes
EPJ Web of Conferences, 2017 Devices based on zinc complexes with sulphanylaminosubstituted ligands are characterized by dual function – electroluminescence (EL) and photosensitivity. Both EL and photosensitivity are associated with the formation of exciplexes.

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
, 2017 The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...

New Methods for Quantification of Visual Photosensitivity Threshold and Symptoms
Translational Vision Science & Technology, 2017 Purpose Visual photosensitivity is a common symptom difficult to measure and diagnose, and is found in many ocular and neurological disorders. We developed two novel reproducible quantitative assessments of visual photosensitivity.
