- The prevalence, distribution, and location of dental caries were studied in complete and partial human dentitions dating from the Viking Age dating (900-1050 AD) excavated in Kopparsvik on island of Gotland, Sweden. 18 individuals and a total of 370 teeth were examined, using a strong light source and dental probe. Carious lesions were found in a large number of the individuals, 14 out of 18. The percentage of teeth affected by caries (11,9%) corresponds well with studied skull materials from the same period. The surface most susceptible to caries was the occlusal surface, whereas only a few proximal lesions and one single carious root surface was found. The tooth most commonly affected by caries was the mandibular first molar. The tooth most commonly missing ante-mortem was also the mandibular molar, and the tooth most commonly missing post mortem was the mandibular incisor. Other findings included apical infections, which were detected clinically in 3% of the teeth.

- Objective: Within the fields of anthropology and osteoarcheology, human teeth have long been studied to understand the diet, habits, and diseases of past civilizations. However, no complete review has been published to collect and analyze the extensive available data on caries prevalence in European man (Homo sapiens) over time. Method: In this current study, the two databases, Scopus and Art, Design, and Architecture Collection, were searched using predefined search terms. The literature was systematically reviewed and assessed by two of the authors. Results: The findings include a significant nonlinear correlation with increasing caries prevalence in European populations from 9000 BC to 1850 AD, for both the number of carious teeth and the number of affected individuals. Conclusion: Despite the well-established collective belief that caries rates fluctuate between different locations and time and the general view that caries rates have increased from prehistoric times and onwards, this is to our knowledge the first time this relationship has been proven based on published data.

Animals and Humans : Human-animal interaction in northern Sweden during the late glacial and postglacial time
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- When the last remnant of the Weichsel glacier melted in northern Sweden, around 7000 BC, pioneer settlers entered virgin land, following their prey, which in turn followed the vegetation dispersion. Some of the settlers derived from the east and the northeast and spread from the Russian taiga, through Finland and into northern Sweden, the study area for this thesis. Some of the settlers derived from southwest Europe and spread through Denmark, into south Sweden and northwards. These two main flows of people moved in small groups over large areas, close to the ice margin and shared a lithic technology, but with some differences. These differences can be traced in the debris at archaeological sites, along with calcined animal bones. This thesis focuses on the calcined bones and the seemingly most important prey for the southern and eastern settlers respectively, and the changes that occurred during the time frame of 9000-4000 BC. This has been done by identifying Mesolithic sites with calcined bones, selecting bone samples from the assemblages, determining species and radiocarbon dating the samples. The species in focus are reindeer (Rangifer tarandus), elk (Alces alces), beaver (Castor fiber) and seal (Phoca sp.), mainly ringed seal (Phoca hispida), which are the largest and most common species found at the sites. To support the results, previously radiocarbon-dated calcined-bone samples and charcoal samples, found in connection with species-determined bones, are included. This study shows that the people moving in from the Russian taiga in the east hunted terrestrial mammals (reindeers and elks) in the beginning. They continued doing so, even when they reached the coast of the Baltic Sea, where the ringed seal lived at the time. Not until several thousands of years later were the first seal bones left at Mesolithic sites in northernmost Norrland. The people moving in from the south, on the other hand, hunted both terrestrial mammals and seal. Using an additional set of dates from an expanded area in Sweden, together with southern Norway, it is shown that around the 8.2 k BP cold event (6200 BC), the inland settlers changed their prey from a high-ranked prey to a low-ranked prey owing to population growth and climate change.

- The patterns of DNA degradation are partly known. Cold and dry environments with a neutral or slightly above neutral pH will preserve DNA better than hot, humid, or acidic conditions. But little is yet known on what types of material preserves DNA. So far, most of the genetic studies on ancient specimens have been conducted on mammals with large bones, few studies have been done on micro mammals. Here we investigate the possibility to retrieve DNA from small mammalian bones, from hedgehogs, from the Baltic island Gotland. We use bones from ancient hedgehogs from known archaeological sites. Of the 13 samples used in the study, all between 5000 and 1000 years old, 6 yielded reproducible DNA that could be assigned to hedgehog. We conclude that it is possible to retrieve DNA, and that this opens the possibility to study early migrations routs to the Baltic island Gotland.

Neolithic Hedgehogs (Erinaceus europaeus) from the Island of Gotland show early contacts with the Swedish mainland

- Previous research probing early migrations and contacts in the Baltic Sea area is characterized by the analysis of different chronologies and subsistent strategies on all sides of the Sea. Several studies performed on artifact typology, ceramics, grave rituals and physical anthropology ended with varying results. Although the question of human origins remains inconclusive, in this study, we rely on the phylogeography of an animal associated with humans to elucidate findings regarding prehistoric human migration and contacts. Hedgehogs, along with other fauna on Gotland, were brought over to the island by humans. We examined hedgehog mitochondrial DNA from the Pitted Ware Culture (Middle Neolithic). The genetic signatures of the animals on the island were investigated to determine the animals origin. From the 23 bones originally examined, twelve bones from all five locations studied yielded reliable results and resembled published extant Erinaceus europaeus sequences from Sweden, Norway and Denmark. We postulate that a western heritage for the Neolithic hedgehogs on Gotland indicates early human contact with the Swedish mainland.

King Olaf's men? : Contextualizing Viking burials at S:t Olofsholm, Gotland, Sweden
- 2023

Tidskriftsartikel (refereegranskat)abstract
- The discovery of burials at S:t Olofsholm, a site associated with the Saint Olaf cult on Gotland in Sweden, has enabled a bioarchaeological contextualization of medieval legends and sagas in conjunction with the archaelogical record. This study seeks to illuminate who were buried at S:t Olofsholm, through a biocultural lens, and whether these burials can be linked to folklore and sagas associated with the site. Five burials of possibly six individuals (cal. AD 980-1270) were assessed macroscopically and through stable isotope analysis (delta C-13, delta N-15, delta S-34, Sr-87/Sr-86, and delta O-18) of incremental dentine, bulk enamel, and bone samples. Sagas and legends associated with S:t Olofsholm mention episodes of conflict and contact involving King Olaf Haraldsson of Norway (later canonized as Saint Olaf), Gutes and Icelanders, and travels between Norway and Kyiv Rus. Two (or three) burials show signs of violent deaths, including evidence of sharp force trauma and burning. Isotope analyses indicate local and non-local signals, with possible links to southern Scandinavia, Britain, Iceland, the Baltics, and Kyiv Rus. In general, the evidence neither challenges nor confirms the legends and sagas associated with S:t Olofsholm. Instead, the findings illustrate the site's function as an early Christian place of worship within a wider Viking world that was characterized by travel and contact across the Baltic Sea, Scandinavia, and beyond. The burials at S:t Olofsholm are likely to be non-normative as indicated by their place of interment and the violent cause of death of most individuals.

Monitoring of influenza virus hemagglutinin in process samples using weak affinity ligands and surface plasmon resonance
- 2008

Ingår i: Analytica Chimica Acta. - : Elsevier. - 0003-2670 .- 1873-4324. ; 623, s. 66-75

Tidskriftsartikel (refereegranskat)abstract
- Surface plasmon resonance (SPR) was used to screen the interaction between a variety of affinity ligands and hemagglutinin (HA) from human influenza virus, with the aim of identifying low affinity ligands useful for the development of a rapid bioanalytical sensor. Three sialic acid-based structures and four lectins were evaluated as sensor ligands. The sialic acid-based ligands included a natural sialic acid-containing glycoprotein, human α1-acid glycoprotein (α1-AGP), and two synthetic 6′-sialyllactose-conjugates, with varying degree of substitution. The interaction of HA with the four lectin-based ligands, concanavalin A (Con A), wheat germ agglutinin (WGA), Maackia amurensis lectin (MAL), and Sambucus nigra agglutinin (SNA), showed a wide variation of affinity strengths. Affinity and kinetics data were estimated. Strong affinities were observed for Con A, WGA, α1-AGP, and a 6′-sialyllactose-conjugate with a high substitution degree, and low affinities were observed for MAL and a 6′-sialyllactose-conjugate with low substitution. The main objective, to identify a low affinity ligand which could be used for on-line monitoring and product quantification, was met by a 6′-sialyllactose–ovalbumin conjugate that had 0.6 mol ligand per mol carrier protein. The apparent affinity of this ligand was estimated to be 1.5 ± 0.03 μM (KD) on the SPR surface. Vaccine process samples containing HA were analyzed in the range 10–100 μg HA mL−1 and correlated with single-radial immunodiffusion. The coefficient of variation on the same chip was between 0.010 and 0.091.
