Pediatric photosensitivity [PDF]

open access: yesPhotodermatology, 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

Electroluminescence and photosensitivity spectra of organic diode structures based on zinc complexes

open access: yesEPJ 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.

Optical Sensor Based on a Single CdS Nanobelt

open access: yesSensors, 2014
In this paper, an optical sensor based on a cadmium sulfide (CdS) nanobelt has been developed. The CdS nanobelt was synthesized by the vapor phase transportation (VPT) method.

One photon and two photon process in photo-decomposition of germanium oxygen deficient centres

open access: yes, 1998
UV photon-induced transformation of germanium oxygen deficient centres (GODC) in germanium-doped silica glass have been studied using photocurrent measurements, absorption and fluorescence bleaching.

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]

open access: yes, 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 ...

Polymorph-induced photosensitivity change in titanylphthalocyanine revealed by the charge transfer integral

open access: yesNanophotonics, 2019
The crystal form of semiconductor materials is keenly correlated with the photosensitivity of optoelectronic devices. Thus, understanding the crystal form-dependent photosensitivity mechanism is critical.

Delayed photosensitivity in a child with erythropoietic protoporphyria : a case report

open access: yesSAGE Open Medical Case Reports, 2018
Erythropoietic protoporphyria (EPP) is a genetically inherited disease that causes protoporphyrin accumulation in erythrocytes, skin, liver, bile, and stool. Clinically this manifests as photosensitivity with painful, edematous cutaneous porphyria.

Automated photosensitivity enhancement in optical fiber tapers

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications
An alternative technique that uses a flame-brush at high temperature to enhance UV light photosensitivity in an optical fiber is described. An extreme low-cost air aspirated propane-butane mini-torch is used, which produces a lower temperature flame than

Kindler′s syndrome: A tale of two siblings

open access: yesIndian Journal of Dermatology, 2016
Kindler′s syndrome (KS) is a rare inherited skin disease characterized by acral blistering, photosensitivity, progressive poikiloderma, and cutaneous atrophy along with different types of mucosal involvement. We hereby report KS in two siblings. The case
