Mesolithic and later sites around the Inner Sound, Scotland the work of the Scotland's First Settlers project 1998-2004

Scotland's First Settlers comprised a survey project to locate and examine sites relating to the earliest, Mesolithic, settlement of the Inner Sound, along the coastlands between Skye and the west coast of Scotland. Particular foci of interest included the existence and nature of midden sites, the use of rockshelters and caves, and the different types of lithic raw material in use. In addition, information relating to the human use of the area up to the present day was recorded. Fieldwork took place over five years between 1999 and 2004: the entire coastline of the Inner Sound together with its islands was walked; 129 new archaeological sites were recorded; 36 sites were shovel pitted; 44 test pitted; and one major excavation took place. Excavation at Sand has been particularly exciting as it has resulted in the analysis of a shell midden dating to the early-mid seventh millennium BC, the early Mesolithic of Scotland. This report comprises the results of survey and excavation work as well as detailed artefact reports, full information on ecofacts such as shell, and bone, and information on the development of the landscape and environment, including sea level change. Finally, the broad-scale coverage of the project has led to a number of discussion points that have much to offer further work, both within the area and further afield.

Structure and neurotoxicity of novel amyloids derived from the BRI gene

A number of human neurodegenerative diseases involve aggregated amyloid proteins in the brain, e.g. Alzheimer's disease (beta-amyloid) and Parkinson's disease (alpha-synuclein). Other examples are rare familial dementias which involve the BRI gene. In a British family, mutation of the termination codon extends the reading frame of BRI to yield a furin-processed 34-residue peptide (Abri; British dementia peptide), 11 residues longer than the wild-type (WT). In a Danish family, a ten-base insertion also yields a 34-residue peptide (Adan; Danish dementia peptide). To explore the roles of Abri and Adan in neurodegeneration, we synthesized Abri and Adan in oxidized and reduced forms and generated transgenic mice colonies expressing the WT and mutated forms of BRI. We have generated transgenic mice colonies bearing the genes coding for WT-BRI, Adan and Abri under the control of the Thy1 promoter. Whereas WT-BRI transgenic mice express full-length WT-BRI protein in their brains, Adan protein is fully processed to small peptides.
