 | Baehr, Wolfgang | Cloning of frog rod photoreceptor cGMP phosphodiesterase subunits (P-alpha, P-beta, P-gamma) and identification of P-gamma) sites involved in the stimulation of cGMP binding to P-alpha and P-beta non-catalytic sites | Retinal cGMP phosphodiesterase (PDE6) is a key enzyme in vertebrate phototransduction. Rod PDE contains two homologous catalytic subunits (Pd two identical regulatory subunits (P). Biochemical studies have shown that amphibian P has high affinity, cGMP-specific, non-catalytic binding sites and that ... | Phototransduction; Retinal cGMP phosphodiesterase; Amphibian PDE | 2002 |

 | Crandall, Alan S. | Torn posterior capsule: prevention, recognition and management | Modern cataract surgery performed with phacoemulsification allows meticulous intraocular control and minimal incision size, but has the inherent risk of capsular rupture. Therefore, surgeons performing cataract surgery will inevitably face the complication of a torn posterior capsule.

 | Normann, Richard A. | Statistical encoding model for a primary motor cortical brain-computer interface | A number of studies of the motor system suggest that the majority of primary motor cortical neurons represent simple movement-related kinematic and dynamic quantities in their time-varying activity patterns. An example of such an encoding relationship is the cosine tuning of firing rate with respect... | Discrete Distribution; LN Model; Neural Decoding; Neuroprosthetics; Sequential Monte-Carlo Filter | 2005 |
