To determine the cerebral metabolism of patients with cortical visual loss. Two observational case studies. Two patients who survived acute organophosphate poisoning with respiratory failure experienced severe visual loss despite relatively normal ophthalmic examination results. Magnetic resonance imaging of the
Several laboratories have now shown that monoclonal antibodies having enzyme-like properties can be generated. The generation of catalytic antibodies makes use of the same basic procedures that have been used for the generation of binding monoclonal antibodies, yet the process

Extensive kinetic studies of bovine intestinal 5'-nucleotide phosphodiesterase as a function of pH have confirmed and amplified the catalytic mechanism previously proposed on the basis of isolation of a covalent phosphorylated intermediate (Landt, M., and Butler, L.G. (1978) Biochemistry 17

A "Batch" microcalorimeter is used at 30 degrees C for the study of the hydrolysis of 4-nitro-phenylphenylphosphonate with a calf-intestinal phosphonate esterase, in a tris buffer, pH 8. The yield of enzymatic hydrolysis is estimated by spectrophotometric determination of the
