Digitization in Archival Material Conservation Processes

Conservation, Preservation, and Digitization

Considerable attention has been focused recently on the problems of conservation and preservation of library materials. Particularly daunting are the scale of the problems and the enormous ongoing investment that will be required to address them. Currently proposed approaches include extensive microfilming of material, deacidification, and other repair measures. It is proposed that digital tech...

Diagnosis of complete molar pregnancy by microsatellites in archival material.

AIMS To develop an assay which would determine the parentage of hydatidiform molar pregnancies. METHODS DNA was extracted from formalin fixed, paraffin wax embedded tissue from hydatidiform molar pregnancies and spontaneous abortions after separation of chorionic villi and decidua. PCR amplification of dinucleotide repeat sequences ("microsatellites") was performed using three different prime...

Recovery of ranavirus dsDNA from formalin-fixed archival material.

The extraction and amplification of nucleic acid from formalin-fixed and paraffin-embedded tissues has become an important exercise in the collection of retrospective epidemiological data. A protocol is described that enables the extraction and amplification of dsDNA from fixed tissues within paraffin blocks and from specimens stored in 10% (aq) formalin. The procedure can be used for the exami...

Conservation and Variation between Supplemental Material

Considering evolutionary processes in conservation biology.

Conservation biologists assign population distinctiveness by classifying populations as evolutionarily significant units (ESUs). Historically, this classification has included ecological and genetic data. However, recent ESU concepts, coupled with increasing availability of data on neutral genetic variation, have led to criteria based exclusively on molecular phylogenies. We argue that the earl...
