The objective of this prospective, monocentric phase-II pilot study was to evaluate toxicity and efficacy of neoadjuvant temozolomide (TMZ) and 13-cis retinoic acid (13-cRA) treatment in patients with newly diagnosed anaplastic gliomas after total or subtotal tumor resection. The primary

Photoisomerization of 11-cis-retinal to all-trans-retinal triggers phototransduction in the retinal photoreceptor cells and causes ultimately the sensation of vision. 11-cis-Retinal is enzymatically regenerated through a complex set of reactions in adjacent retinal pigment epithelial cells (RPE). In this study using

Femtosecond spectroscopy is used to compare photochemical dynamics in light-adapted and dark-adapted bacteriorhodopsin (BR). The retinal prosthetic group is initially all-trans in the former, while it is nearly a 1:1 mixture with 13-cis in the latter. Comparing photochemistry in both
