1. Sistema eletrônico de controle para laser amarelo de aplicação oftalmológica com regime de operação contínuo e micro-pulsado / Electronic control system to yellow laser for ophthalmic applications and continuous or micro second pulse regime
Recently, scientists have proposed a new technique for treating diseases related to the human retina, which is based on retinal laser discharges using pulse sequence around of 200 \ mü\ s, replacing the conventional treatment using long pulses around of 300 ms. The main advantage of the new technique is the conservation (without cell death) of the area expo

2. Initiation of active contraction by photogeneration of adenosine-5'-triphosphate in rabbit psoas muscle fibres.
Mechanical and biochemical descriptions of the muscle cross-bridge cycle have been correlated. Skinned muscle fibres of rabbit psoas muscle in rigor were incubated in solutions containing approximately equal to 30 microM-Ca2+ ions and P3-1-(2-nitro)phenylethyladenosine-5'-triphosphate, 'caged ATP', an inert photolabile precursor of ATP. ATP was liberated fro
