Is the Photoinduced Isomerization in Retinal Protonated Schiff Bases a Single- or Double-Torsional Process?
Nonadiabatic photodynamical simulations are presented for the all-trans and 5-cis isomers of the hepta-3,5,7- trieniminium cation (PSB4) to characterize the types of torsional modes occurring in the cis-trans isomerization processes in retinal

Dual photoisomerization on distinct potential energy surfaces in a UV-absorbing rhodopsin
of life. Unlike the well-known visible-absorbing rhodopsins, which bind a protonated retinal Schiff base for light absorption, UV-absorbing rhodopsins bind an unprotonated retinal Schiff base...

Synthesis and characterization of a cobalt(II) complex with(E)-ń-(2-Hydroxy-3-Methoxybenzylidene)isonicotinohydrazide and (E)-ń-(2-Hydroxy-3-Methoxybenzylidene)isonicotinohydrazidanium nitrate as a by-product
A Schiff base ligand HL was synthesized from the reaction of isonicotinic acid hydrazide with 3-methoxysalicylaldehyde. The reaction of HL with Co(NO3)2 .6H2O in methanol gave dark red crystals of [Co(HL)2](NO3)2.3H2O and colorless ...

Carotenoid response to retinal excitation and photoisomerization dynamics in xanthorhodopsin
Paper presents a comparative study of xanthorhodopsin, a proton pump. Upon excitation of retinal, xanthorhodopsin exhibits a wavy transient absorption to electrochromic effect of the transient electric field of excited retinal

Quantification of rat retinal growth and vascular population changes after single and split doses of proton irradiation: translational study using stereology methods.
This study quatified architectural and population changes in the rat retinal vasculature after proton irradiation using stereology. It was found that a progressive time- and dose-dependent endothelial cell loss occurred over 15 to 2...
