Background
Mild cognitive impairment (MCI) was recently described as a heterogeneous group with a variety of clinical outcomes and high risk to develop Alzheimer's disease (AD). Regional cerebral blood flow (rCBF) as measured by single photon emission computed tomography (SPECT) was used to study the heterogeneity of MCI and to look for predictors of future development of AD. 相似文献72.

A rapid procedure for the purification of fructose-1,6-bisphosphate aldolase from spinach chloroplasts is presented which involves two steps; precipitation of bulk protein with polyethylene glycol and partitioning of remaining soluble protein in aqueous two-phase systems. A 94% pure preparation is obtained within 6h with a yield of 19%. A marked difference in the partition behaviour of the aldolase activity from whole leaf tissue suggested that the procedure is less efficient when leaf extract is used as starting material.Abbreviations EDTA

A diffusion cell described in the preceding paper has been used to determine mutual and intradiffusion coefficients for various compounds in the range 2–2000 × 10?12 m2 s?1. The results are in good agreement with previously reported values. The standard deviation in a series of 13 runs on serum albumin performed in four different instruments was 6%. 相似文献
