High performance photoinitiating systems for holography recording: need for a full control of primary processes.

Optimization of holography recording in photopolymers was studied from the point of view of a quite general process, that is, the photogeneration of radicals. On the basis of a dye/coinitiator photoinitiating system, the effect of primary events and their relative efficiency was investigated with respect to the final overall properties, such as the diffraction efficiency. Quenching of the dye excited states by the borate salts coinitiators exhibits important differences depending on the dye used (Rose Bengal or Safranine O).

Assessment of patient satisfaction with outcomes of and ophthalmic care for cataract surgery.

Purpose: To assess patient satisfaction with cataract surgery care.

Setting: Private and public health ophthalmic centers, France.

Methods: This prospective longitudinal multicenter observational study enrolled patients attending consultation for a preoperative visit from September 2007 to February 2008.

Correlates of cognitive deficits in first episode schizophrenia.

Objective: The presence of cognitive dysfunction in schizophrenia has been well documented, but questions remain about whether there are relationships between this dysfunction and clinical symptomatology. If present, such relationships should be most clearly observable in patients with first episode schizophrenia; that is, before the effects of chronic illness, institutionalization, or treatment might confound them.

Method: 307 schizophrenia subjects in their first episode of illness were recruited to participate in a clinical trial comparing the long-term efficacy of haloperidol and risperidone.
