Vegetal grave goods in a female burial on Bornholm (Denmark) from the Late Roman Iron Age period interpreted in a comparative European perspective

Knowledge about the healing properties of plant substances is probably as old as humankind, and this can be demonstrated by botanical finds in archaeological contexts. Southern Scandinavia has a long tradition of supplying deceased persons with vegetal material for use in their afterlife, as shown by single seeds or processed plants in the form of foods, drinks or medicines. A wellknown example is the small container made of birch bark most probably filled with a kind of mead produced from honey, in the Egtved girl’s coffin a find which has been dated to the Early Bronze Age.Another fascinating plant discovery derives fromthe grave of the Fyrkat woman dated to the Viking Age: a handful seeds of the poisonous plant henbane (Hyoscyamus niger) was found in a small pocket fixed to the woman’s belt. Plant materials enclosed in small amulet boxes are quite common and are frequently attached to necklaces that the deceased had certainly worn during their lives. In this article, we discuss the organic finds from a newly excavated amulet box which was discovered in a woman’s grave at the Late Roman Iron Age site of Vellensby, on the island of Bornholm. The box contained two ‘chewing gum-like objects’ with dental impressions and three vegetal objects. Gas chromatography/mass spectrometry analysis was applied to one of the ‘chewing gums’ and the results show that it consists of a mixture of birch tar and plant oil. Based on their morphological characteristics, the three uncharred plant parts could be identified as cloves from a wild species of Allium, probably A. scorodoprasum (sand leek). The traditional medicinal application of sand leek is presented and the symbolic and possible principal meaning of amulet boxes is discussed within a comparative study of related discoveries from female burials throughout Europe

Lead concentrations in blood from incubating common eiders (Somateria mollissima) in the Baltic Sea

Here we investigate if lead may be a contributing factor to the observed population decline in a Baltic colony of incubating eiders (Somateria mollissima). Body mass and blood samples were obtained from 50 incubating female eiders at the Baltic breeding colony on Christiansø during spring 2017 (n = 27) and 2018 (n = 23). All the females were sampled twice during early (day 4) and late (day 24) incubation. The full blood was analysed for lead to investigate if the concentrations exceeded toxic thresholds or changed over the incubation period due to remobilisation from bones and liver tissue. Body mass, hatch date and number of chicks were also analysed with respect to lead concentrations. The body mass (mean ± SD g) increased significantly in the order: day 24 in 2018 (1561 ± 154 g) Peer reviewe

Excessive substance use in bipolar disorder is associated with impaired functioning rather than clinical characteristics, a descriptive study

<p>Abstract</p> <p>Background</p> <p>There is a strong association between bipolar disorder (BD) and substance use disorder (SUD). The clinical and functional correlates of SUD in BD are still unclear and little is known about the role of excessive substance use that does not meet SUD criteria. Thus, the aims of the current study were to investigate lifetime rates of illicit substance use in BD relative to the normal population and if there are differences in clinical and functional features between BD patients with and without excessive substance use.</p> <p>Methods</p> <p>125 consecutively recruited BD in- and outpatients from the Oslo University Hospitals and 327 persons randomly drawn from the population in Oslo, Norway participated. Clinical and functional variables were assessed. Excessive substance use was defined as DSM-IV SUD and/or excessive use according to predefined criteria.</p> <p>Results</p> <p>The rate of lifetime illicit substance use was significantly higher among patients compared to the reference population (OR = 3.03, CI = 1.9-4.8, p < .001). Patients with excessive substance use (45% of total) had poorer educational level, occupational status, GAF-scores and medication compliance, with a trend towards higher suicidality rates, compared to patients without. There were no significant group differences in current symptom levels or disease course between groups.</p> <p>Conclusion</p> <p>The percentage of patients with BD that had tried illicit substances was significantly higher than in the normal population. BD patients with excessive substance use clearly had impaired functioning, but not a worse course of illness compared to patients without excessive substance use. An assessment of substance use beyond SUD criteria in BD is clinically relevant.</p
