Photosensitivity at 1550 nm and Bragg grating inscription in As2Se3 microwires [PDF]
, 2011 We report the first experimental observation of photosensitivity in As2Se3 glass at a wavelength of 1550 nm. We utilize this photosensitivity to induce the first Bragg gratings using a laser source at a wavelength of 1550 nm. We quantify the photosensitivity thresholds related to exposition intensity and exposition time.

Use of antihypertensive drugs and risk of keratinocyte carcinoma: A meta‐analysis of observational studies [PDF]
, 2018 Purpose Current epidemiologic evidence on the association between antihypertensive drugs and keratinocyte carcinoma (KC) risk is inconsistent. We sought to quantify this association by meta‐analysis of observational studies.

Impact of photosensitizers activation on intracellular trafficking and viscosity. [PDF]
PLoS ONE, 2013 The intracellular microenvironment is essential for the efficiency of photo-induced therapies, as short-lived reactive oxygen species generated must diffuse through their intracellular surrounding medium to reach their cellular target. Here, by combining

Recent Advances of Photoactive Near-Infrared Carbon Dots in Cancer Photodynamic Therapy
Pharmaceutics, 2023 Photodynamic therapy (PDT) is a treatment that employs exogenously produced reactive oxygen species (ROS) to kill cancer cells. ROS are generated from the interaction of excited-state photosensitizers (PSs) or photosensitizing agents with molecular ...

A Study of the Operation of Especially Designed Photosensitive Gaseous Detectors at Cryogenic Temperatures [PDF]
, 2005 In some experiments and applications there is need for large-area photosensitive detectors to operate at cryogenic temperatures. Nowadays, vacuum PMs are usually used for this purpose. We have developed special designs of planar photosensitive gaseous detectors able to operate at cryogenic temperatures.
