The distribution of ACE genotypes in the Spanish population was as follows ACE-I/I 14.8% in controls and 20.5% in AD ACE-I/D 45.6% in controls and 46.0% in AD and ACE-D/D 39.6% in controls and 33.5% in AD (623). In this study, a small increase in the frequency of ACE- allele was observed in LOAD (623). Nevertheless, as with many other polymorphic genes, some authors did not find association between the ACE-I/D polymorphism and AD in different populations (80,617,624-631). However, a meta-analysis of 12 case-control series published up to the year 2000 suggested that ACi genotypes are associated with AD (611), and that the ACE-D allele is more frequent in Spanish, American, and Russian AD patients than in controls (614,615,617) but not in the Italian and Jewish populations (627,632).

In SPE, a small amount of organic solvent or surfactant is added to collected samples to prevent adsorption to sample containers. To increase recoveries of ng 1 levels of PAHs in SPE, ACN (40%) or surfactants above their CMC can be added to samples prior to preconcentration. Solid supports, chemically modified with copper phthalocyanine trisulfonic acid derivatives for selective sorption of PAHs, have been investigated. The selective interaction is thought to be with the tt electrons of the PAHs. Brij-35, a neutral polyoxyethylene lauryl ether surfactant was added above the CMC to water samples to prevent sorption on container walls. Before preconcentration by SPE, samples were diluted to reduce the surfactant concentration to just below the CMC. Recoveries of over 90% for SPE on solids containing copper phthalocyanine trisulfonic derivatives were obtained for spiked water samples at low ngl levels, except for NAP, ACE, and FLU. Experiments repeated using a C18 SPE preconcentration sorbent gave >90% recovery for all 16 EPA PAHs, except for ACY. Examples of the use of SDB as an SPE sorbent include the online analysis of seawater from the coast of Catalonia in Spain, where no PAHs above the low ng 1 level were detected, and the analysis of leachate from coal deposits. ...

Chemical analysis of ACI-B, ACE-B and PHW-B are shown in Table 1. Major constituents were neutral sugars(fucose and mannose in Mol. ratios of 1 2.3-2.5) and proteins. Phosphate was... 

To elucidate whether the serologically reactive site is a carbohydrate or a protein moiety, ACI-B was subjected to periodate oxidation and digestion with proteolytic enzymes. Portions of periodate oxidized ACI-B and pronase/trypsin-digested ACI-B were examined by immunodiffusion with anti ACE serum. Periodate-oxidized ACI-B and its serial dilutions in saline were also used for the precipitin reaction in a fine glass tube. Periodate-oxidized ACI-B did not react with the antiserum, but digestion of ACI-B with pronase and trypsin did not affect its serological reactivity. The immunodiffusion pattern fused completely. From these results, it is estimated that the intracellular mannan-rich fraction possesses serological activity.
