Light modulated cnidocyte discharge predates the origins of eyes in Cnidaria
Ecology and Evolution, 2021 Complex biological traits often originate by integrating previously separate parts, but the organismal functions of these precursors are challenging to infer.

Haemlacria: A mini case series of a rare condition
Journal of Family Medicine and Primary Care, 2021 Haemlacria is a rare condition which is not widely mentioned in literature. In this mini case series, we describe two cases with this presentation. Both the patients were women with unilateral presentation of haemlacria in the right eye.

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 ...

Doxycycline-induced photosensitivity in patients treated for erythema migrans
BMC Infectious Diseases, 2018 Background Doxycycline is one of the recommended antibiotics for treating erythema migrans (EM). Since EM predominantly occurs during summer, the potential of doxycycline to induce photosensitivity is of concern. In studies on the efficacy of doxycycline

Photosensitization and controlled photosensitization with BODIPY dyes [PDF]
Coordination Chemistry Reviews, 2019 Abstract Highly versatile BODIPY dyes proved themselves to be very useful as photosensitizers. These dyes can be derivatized to absorb essentially anywhere in the visible the near IR region of the spectrum. As a result of their diverse reactivity, singlet oxygen generation efficiency can be modulated very precisely, leading to a number of selective ...

Ultra-wide detuning planar Bragg grating fabrication technique based on direct UV grating writing with electro-optic phase modulation [PDF]
, 2013 A direct UV grating writing technique based on phase-controlled interferometry is proposed and demonstrated in a silica-on-silicon platform, with a wider wavelength detuning range than any previously reported UV writing technology.
