Isolated alpha-, beta-, and gamma-crystallins from young rat lenses were incubated in solution for 16 hr with 3-hydroxykynurenine under ultraviolet (366 nm) light. Controls included: incubation without light, without kynurenine, and with 2-mercaptoethanol. These procedures generated several chromophors (with absorption maxima or shoulders at 340, 370, and 470 nm) and fluorophors (with excitatio...

We report the comparative investigation of fabricating type-II waveguide lasers in Nd:Y3Al5O12 (Nd:YAG) using femtosecond laser pulses at 515 and 1030 nm. focus on comparison track morphologies, modification thresholds, overall efficiency ultrafast inscription (ULI) process creating these waveguides. For both wavelengths, we demonstrated low propagation losses 0.2 dB/cm. achieved lowest reporte...

Noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonists such as phencyclidine are psychotomimetics and disrupt prepulse inhibition (PPI), a measure of sensorimotor gating that is deficient in schizophrenia. Systemically administered competitive NMDA receptor antagonists do not disrupt PPI in rats, leading to speculation that these compounds might have use as neuroprotective agents witho...

The P515/535 module has become available as a new accessory for the DUAL-PAM-100. It serves for simultaneous measurements of the dual beam 550 515 nm difference signal, reflecting the electrochromic pigment shift (ECS, P515), and of the single beam 535 nm signal, reflecting "membrane energization" ("scattering" changes). The technical features of the emitter and detector units of the new device...
