Article Reference MEMOR: A database of archeological human remains collections from Flanders, Belgium
Abstract The aim of this article is to describe a newly created open access database of archeological human remains collections from Flanders, Belgium. The MEMOR database (www.memor.be) was created to provide an overview of the current practices of loans, reburial, and the research potential of human skeletons from archeological sites currently stored in Flanders. In addition, the project aimed to provide a legal and ethical framework for the handling of human remains and was created around stakeholder involvement from anthropologists, geneticists, contract archeologists, the local, regional and national government agencies, local and national government, universities, and representatives of the major religions. The project has resulted in the creation of a rich database with many collections available for study. The database was created using the open-source Arches data management platform that is freely available for organizations worldwide to configure in accordance with their individual needs and without restrictions on its use. Each collection is linked to information about the excavation and the site the remains originate from, its size and time period. In addition, a research potential tab reveals whether any analyses were performed, and whether excavation notes are available with the assemblage. The database currently contains 742 collections, ranging in size from 1 to over 1000 individuals. New collections will continue to be added when new assemblages are excavated and studied. The database can also be expanded to include human remains collections from other regions and other material categories, such as archaeozoological collections.

Article Reference Mesocyclops thermocyclopoides species-group: redefinition and content
Within the genus Mesocyclops the thermocyclopoides species-group is defined on the basis of the presence of spiniform armature on the maxillar coxa. Examination of nineteen, mainly Palaeotropical species of Mesocyclops and nine representatives of the closely related genus Thermocyclops revealed, that the coxal part of the maxillar syncoxa of the species recently unified in the thermocyclopoides group is adorned with distinct rows of big spinules on its frontal surface. This character, with only one known exception in South Indian M. cf. papuensis, is absent in other species of Mesocyclops and all the Thermocyclops studied here. These species have no spinules on the maxillar coxa at all or very tiny scattered ones. © 1994 Kluwer Academic Publishers.

Article Reference Octet Stream Metallothionein gene and protein expression as a biomarker for metal pollution in natural gudgeon populations
Gudgeons (Gobio gobio) from historically Cd and Zn contaminated sites in Flanders (Belgium) were found to be resistant to elevated Cd levels. In previous work, this increased resistance was largely explained by increased metallothionein (MT) expression. Recently, environmental cleanup efforts resulted in a significant decrease in Cd concentrations in the surface water. In this study, we evaluated the use of hepatic metal and metallothionein (MT) concentrations as biomarkers of metal exposure before and after the cleanup. Hepatic MT mRNA levels were determined after the environmental metal levels decreased in order to assess the applicability of MT gene expression as an environmental biomarker in natural fish populations. Our data show that both metallothionein protein and gene expression have the potential to be sensitive biomarkers for metal exposure. Significant correlations were found (a) among accumulated metal concentrations and both MT protein and mRNA levels, and (b) between MT protein and mRNA levels. However, our data illustrated that while MT protein and gene expression give a quantitative picture of metal load at a single time point, quantitative information in natural populations cannot always be obtained when different time points (including different years) are compared, since MT gene and protein expression are affected by many other factors in addition to the metal load. Furthermore, the result of the environmental cleanup was reflected in a decrease of hepatic Cd concentrations. Zn remained the most important factor determining MT concentrations. Finally, two differently sized MT mRNAs were amplified to test the hypothesis that 3′-UTR length can offer a protective advantage in conditions of environmental stress. Our data provided no evidence to support this hypothesis. In contrast, the ratio of the long mRNA variant relative to total MT mRNA was surprisingly constant, and independent of exposure history. © 2007 Elsevier B.V. All rights reserved.

Article Reference Method assessment and observer variation in age estimation: A comparative analysis of the Suchey-Brooks and the İşcan methods on an archaeological medieval population
Age-at-death estimation methods have faced challenges in their applicability to past populations. This study aims to evaluate the assessment and observer variability of the Suchey-Brooks (SB) and İşcan methods within archaeological contexts. Our sample consisted of 400 individuals from the medieval cemetery of the Dunes Abbey in Koksijde, Belgium. The skeletal remains exhibited good preservation, especially for the İşcan methods, which showed higher sensitivity to preservation conditions. Intra- and inter-observer variation were investigated using Spearman correlation coefficients, Wilcoxon paired ranks test, and Cohen's kappa test. The Spearman coefficient revealed a strong positive correlation, with a moderate to almost excellent kappa coefficient for both intra- and inter-observer error. Overall, the SB method displayed better inter-observer agreement, while the İşcan method presented better intra-observer agreement. Applying these methods to younger individuals resulted in less variability. Certain descriptive phase categories, such as phase III for the SB method and phase 3 and 4 for the İşcan methods, seemed problematic. Only 188 sufficiently preserved individuals could be scored using both the SB and the İşcan methods. They were classified into age groups, and the methods assessment were evaluated using the same statistical approach. The Spearman correlation coefficient indicated consistent age group attribution between the two methods (rho = 0.92), with a moderate to almost excellent agreement (k = 0.45; wk = 0.91). Overall, the two methods mainly differ by only one age group, except for older adults. The SB method tended to assign older age groups compared to İşcan's method, leading to effective overestimation.

Article Reference Micro-computed tomography for natural history specimens: a handbook of best practice protocols
Micro-computed tomography (micro-CT or microtomography) is a non-destructive imaging technique using X-rays which allows the digitisation of an object in three dimensions. The ability of micro-CT imaging to visualise both internal and external features of an object, without destroying the specimen, makes the technique ideal for the digitisation of valuable natural history collections. This handbook serves as a comprehensive guide to laboratory micro-CT imaging of different types of natural history specimens, including zoological, botanical, palaeontological and geological samples.
