    Description: The apolipoprotein E (APOE) gene is the only genetic risk factor that has so far been linked to risk for late-onset Alzheimer's disease (LOAD). However, 50 percent of Alzheimer's disease cases do not carry an APOE4 allele, suggesting that other risk factors must exist. We performed a two-stage genome-wide screen in sibling pairs with LOAD to detect other susceptibility loci. Here we report evidence for an Alzheimer's disease locus on chromosome 10. Our stage one multipoint lod score (logarithm of the odds ratio for linkage/no linkage) of 2.48 (266 sibling pairs) increased to 3.83 in stage 2 (429 sibling pairs) close to D10S1225 (79 centimorgans). This locus modifies risk for Alzheimer's disease independent of APOE genotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, A -- Holmans, P -- Marshall, H -- Kwon, J -- Meyer, D -- Ramic, D -- Shears, S -- Booth, J -- DeVrieze, F W -- Crook, R -- Hamshere, M -- Abraham, R -- Tunstall, N -- Rice, F -- Carty, S -- Lillystone, S -- Kehoe, P -- Rudrasingham, V -- Jones, L -- Lovestone, S -- Perez-Tur, J -- Williams, J -- Owen, M J -- Hardy, J -- Goate, A M -- AG16208/AG/NIA NIH HHS/ -- AG5681/AG/NIA NIH HHS/ -- U24 AG021886/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2304-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, Washington University School of Medicine, 660 S.

    Description: The aim of this study was to analyse the interfacial micromorphology of total-etch adhesives and dentin structures different locations by using SEM. Standardized cylindrical cavities (3mm in diameter, 2mm deep) with all margins in dentin were prepared on occlusal and buccal surfaces of twenty extracted human third molars. A total-etch dentin adhesive system and a light-cure flowable composite (Filtek Ultimate Flowable, 3M ESPE, St. Paul, MN, USA) were used in this study. Micro-morphological SEM analysis of the marginal seal of the original tooth specimens was performed using high magnification of up to 1000×. In this study, we found the difference in interfacial micromorphology in dentin different locations. Also, marginal gap was found in both observed dentin area. Better understanding of complexity and three- dimensional variations of the tooth structure is important for prevention of clinical challenges such as postoperative sensitivity, marginal discoloration and secondary caries, which could be prevented by achieving of predictable and long-lasting adhesive bond. In this article, we report on the influence of dentinal orientation on the quality of adhesive bond between composite restorations and dentin different locations. This is important for understanding the occurrence and prevention of microleakage.
