Multicolor chromosome bar codes

Chromosome bar codes are multicolor banding patterns produced by fluorescence in situ hybridization (FISH) with differentially labeled and pooled sub-regional DNA probes. These molecular cytogenetic tools facilitate chromosome identification and the delineation of both inter- and intra-chromosomal rearrangements. We present an overview of the various conceptual approaches which can be largely divided into two classes: Simple bar codes designed for chromosome identification and complex bar codes for high resolution aberration screening of entire karyotypes. We address the issue of color redundancy and how to overcome this limitation by complementation of bar codes with whole chromosome painting probes. Copyright (c) 2006 S. Karger AG, Base

Homologies in human and Macasa fuscata chromosomes revealed by in situ suppression hybridization with human chromosome specific DNA libraries

We established chromosomal homologies between all chromosomes of the human karyotype and that of an old world monkey (Macaca fuscata) by chromosomal in situ suppression (CISS) hybridization with human chromosome specific DNA libraries. Except for the human chromosome 2 library and limited cross-hybridization of X and Y chromosome libraries all human DNA libraries hybridized to single GTG-banded macaque chromosomes. Only three macaque chromosomes (2, 7, 13) were each hybridized by two separate human libraries (7 and 21, 14 and 15, 20 and 22 respectively). Thus, an unequivocally high degree of synteny between human and macaque chromosomes has been maintained for more than 20 million years. As previously suggested, both Papionini (macaques, baboons, mandrills and cercocebus monkeys, all of which have nearly identical karyotypes) and humans are chromosomally conservative. The results suggest, that CISS hybridization can be expected to become an indispensable tool in comparative chromosome and gene mapping and will help clarify chromosomal phylogenies with speed and accuracy

Historical Archaeology in Sweden : from the Middle Ages to Modernity

The article outlines the origin and later transformation of Medieval Archaeology to Historical Archaeology, both as an antiquarian practice and as an academic subject, focusing on the development in Sweden since the 18th C. Where the concept of the Middle Ages defined the former subject, both its opportunities and its limitations, now Modernity has turned up as a new challenging concept. Archaeology has already seen a number of studies into Modernity or the process of modernization going right up to present. However, the Middle Ages and Modernity are both metaphors creating simplified images in our minds, which contribute to preserve the divide between different periods. When I have to choose between an archaeology of the Middle Ages and an archaeology of Modernity, I prefer Historical Archaeology with a rather open definition – the methodological meeting between objects, texts and images

Medieval Tønsberg, the Church and the Hinterland

Sakral geometri - veje og vildveje til viden

Sacred geometry - paths and false paths to knowledge: A large number of examples of so-called sacred geometry are used in a discussion on the qualities of different interpretations of the past. Is it possible and desirable to separate between science and pseudo science, between archaeology and pseudo archaeology? And should archaeologists igonore, understand or criticise pseudo archaeology? My experiences from the study of four traditions within the fie ld of “sacred topographies” show, that it is rather difficult or even impossible to separate archaeology from pseudo archaeology. In the spirit of Karl R. Popper and his critical rationalism I conclude, that archaeology should welcome all kinds of ideas, which then ought to be seriously examined

Four churches and a lighthouse: preservation, ‘creative dismantling’ or destruction

A presentation and discussion of the heritage dilemmas, which appear, when the medieval churches of Mårup, Rubjerg, Lyngby and Furreby and the modern lighthouse of Rubjerg Knude in Northern Jutland, Denmark, all are threatened bydunes, drifting sands and the North Sea. The churches of Rubjerg and Lyngby were taken down and rebuilt further inland in, respectively, 1904 and 1913–1914, while the church of Furreby is still functioning. The lighthouse is standing as a ruinwaiting to be taken down around 2020. The church of Mårup was made redundant, when a new church was built further inland in Lønstrup in 1926–1928. A great dispute emerged on the future of Mårup, when it became threatened by increasing sea erosion in the 1980s. The church was investigated and partly taken down 2008 and 2011. The dispute on Mårup has been seen as a conflict betweennature and culture, periphery and centre, experience and knowledge – preservation and destruction. First, to understand the debate the author introduces the concept ‘creative dismantling’; a concept in between preservation and destruction. Second, the author argues that the unspoken core of the dispute has been the assumed irrelevance of the church to the national canon of art and history by all disputants. The creative dismantling lifted the church into the canon thereby creating a new, but also problematic consensus

Romanesque Round Church Towers in Scandinavia

The aim of the article is to discuss the interpretation of the Romanesque round church towers in Scandinavia. The article focuses on the 15-19 churches with round towers in medieval Denmark, Sweden and Norway, with the main part in Southern Schleswig and Scania; none are known from Finland. The chronology and social context, function and meaning of the church towers are discussed. Finally a list of the round church towers in Scandinavia is presented.Corrections i text-file 2015
