Several studies indicate a possible association between different 4 genes and chronic neurodegenerative diseases including Alzheimer's disease (DTA). To further investigate, we have analyzed association between the apolipoprotein E (apo E) and bleomycin hydrolase (BH) polymorphisms and three groups of elderly patients: control subjects (T) (n = 68), late-onset sporadic DTA patients (DTAst) (n = 65) and other non vascular neurodegerative diseases (MNDA) (n = 52). Apo E-epsilon4 and BH-G alleles frequencies (%) are: 8.2 (T), 31.5 (DTAst), 16.4 (MNDA) and 41.4 (T), 35.6 (DTAst). No association has been observed between carrying the G allele and DTA in F,4 negative subjects but, our data have confirmed the earlier reports: carrying the epsilon4 allele is a dose-dependent risk factor for the DTAst (OR: 6.0, IC 95 %: 2.6-13.7) and decrease the age of symptom onset (p < 0.005). They have also suggested that apo E genotyping may be of interest to perform differential diagnosis of neurodegenerative diseases in elderly subjects.

Spatial statistical analysis was used to compare and quantity the distribution of German cockroaches among harborages before and after application of a repellent solution to these encompassing at least 85% of the cumulative distribution. Trials consisted of 16 yellow lancinated Plexiglas harborages (7.5 by 7.5 cm) in (1.2 by 1.2 m) arenas. and concurrent studies involving 19 harborages in a room 6 by 8 m. Results in arena and room trials were similar. In rooms under a photoperiod or continuous lighting conditions, harborages cumulatively encompassing 89-95% of the population (16 or 19 of 49 harborages) each were treated with a formulation containing 2% n-methyl neodecanamide (MNDA) repellent. All other harborages received an equal volume of water. Subsequent spatial analysis revealed a dramatic shift of 96-98% of the reintroduced cockroach populations to nonrepellent treated harborages: patterns persisted for the duration of the study (28 d (12:12) and 20 days (continuous)). Spatial analysis also was used to quantify the areas of emigration and immigration in experimental rooms resulting from the repellent: 89% of the population was redistributed into harborages occupying, 167 m(2) of the room, leaving 11% of the population in harborages within the remaining 28.5 m(2). Only 2-4% of the population remained in the 16.1 m(2) that originally contained 89% of the cockroach population. This approach allows researchers to quantify the impact of an intervention that changes distribution rather than survivorship. These studies indicated that this formulation clearly precluded populations from re-establishing in previously inhabited harborages under either lighting condition. Implications of these spatial measuring procedures, and the repellent, to a reduced-risk integrated management strategy are discussed, including the concept of herding cockroaches toward areas strategically baited with toxicants.
