Analysis of the medical causes of death in cerebral palsy.

Aim: To investigate causes of death and age at death in cerebral palsy subjects compared with the general population.

Method: Analysis of data supplied by the centre of epidemiology on the medical causes of death within the National Institute of Health and Medical Research in France was conducted. Three thousand and thirty-one death certificates indicating a diagnosis of cerebral palsy (ICD-10 code G80) were reported between 2000 and 2008.

Large crystal growth by thermal control allows combined X-ray and neutron crystallographic studies to elucidate the protonation states in Aspergillus flavus urate oxidase.

Urate oxidase (Uox) catalyses the oxidation of urate to allantoin and is used to reduce toxic urate accumulation during chemotherapy. X-ray structures of Uox with various inhibitors have been determined and yet the detailed catalytic mechanism remains unclear. Neutron crystallography can provide complementary information to that from X-ray studies and allows direct determination of the protonation states of the active-site residues and substrate analogues, provided that large, well-ordered deuterated crystals can be grown.

[Pain in adults with cerebral palsy].

Introduction: Pain is the main problem in patients with cerebral palsy. To improve the quality of life of people with cerebral palsy, a good knowledge of the clinical syndrome is necessary.

Method: We reviewed the published data of the APIB study.

A methodology and an instrument for the temperature-controlled optimization of crystal growth.

A method and a device for the promotion of crystal growth by keeping the crystallization solution metastable during the growth process are described. This is achieved by controlled temperature variation of the crystallization solution using parameters determined in situ during the growth process. The technique finds application in the growth of large high-quality crystals for neutron crystallography.

[Disabilities, access to medical care, and way of life of adults with cerebral palsy. APIB study: initial results].

Unlabelled: Cerebral palsy is defined as a nonprogressive brain lesion that occurs during prenatal or perinatal development. The Breizh IMC health network objective is to improve the knowledge about the way of life and the health status of adults with cerebral palsy.

Objective: To describe disabilities, way of life and access to medical care for older teens and adults with cerebral palsy.

Anomalous Dispersion with Edges in the Soft X-ray Region: First Results of Diffraction from Single Crystals of Trypsin Near the K-Absorption Edge of Sulfur.

Anomalous dispersion of X-ray diffraction at wavelengths near the X-ray K-absorption edge of sulfur at wavelengths around 5 A has been applied to single crystals of trypsin obtained from an ammonium sulfate solution. The multiwavelength anomalous-dispersion method based on 775 unique reflections (+183 Bijvoet mates) measured at three wavelengths near the K-absorption edge of sulfur in trypsin (two methionines and disulfide bridges of six cystines) reproduces the known features of the trypsin structure of a resolution of 4 A. It appears that there is anisotropic anomalous scattering from the disulfide bridges of cystine.

Image plate detectors for macromolecular neutron diffractometry.

Neutron diffraction studies of macromolecules require large position sensitive detectors. It is proposed that such a device can be based on image plate technology, which relies on re-usable photostimuable phosphors, combined with a neutron to gamma-ray converter. Design parameters such as the best wavelength for the neutron radiation and the optimum sample to detector distance are discussed, and a design for a cylindrical detector is outlined.
