Tid, arkeologi och konst : Kulturpelaren i Lund
Time, Archaeology and Art – the Pillar of Culture in Lund. The article is an investigation into how archaeologists and artists may relate to time departing from the so-called “Pillar of Culture” at The Cultural Museum in Lund. The pillar is a six m high stratigraphical section from an excavation in Lund 1913. It was exhibited in 1932 in a context of artifacts from the actual excavation. The pillar
Curation and Reuse : An Experimental Study of Transverse Arrowheads of the Late Scandinavian Mesolithic
This article aims to examine whether it is possible to rework transversearrowheads while still hafted, in order to reuse them. Three series, eachcontaining three arrows, were shot into a target consisting of meat andbone. When possible, the arrowheads were retouched and fired again.The results of the experiments demonstrate that it is possible to reworktransverse arrowheads while they are hafted a
Breastfeeding Initiation and Duration after High Exposure to Perfluoroalkyl Substances through Contaminated Drinking Water: A Cohort Study from Ronneby, Sweden
BACKGROUND AND AIM: The drinking water in parts of Ronneby municipality was heavily contaminated with perfluoroalkyl substances (PFAS) for decades. Although PFAS has endocrine-disrupting properties and may interfere with breastfeeding, the supporting epidemiologic literature is conflicting and based solely on populations with background levels of exposure. The effects on breastfeeding in populatio
Simultaneous Optical and Electrical Characterization of GaN Nanowire Arrays by Means of Vis-IR Spectroscopic Ellipsometry
We report an original and straightforward method for both optical and electrical characterization of vertical GaN nanowire arrays epitaxially grown on silicon through visible-infrared spectroscopic ellipsometry methods. For the initial purpose of adding new inputs to the ellipsometry model, focused ion-beam tomography experiments were conducted to extract porosity/depth profiles of these systems.
Conduct disorder and somatic health in children : a nationwide genetically sensitive study
Background: Conduct disorder (CD), a serious behavioral and emotional disorder in childhood and adolescence, characterized by disruptive behavior and breaking societal rules. Studies have explored the overlap of CD with neurodevelopmental problems (NDP). The somatic health of children with NDP has been investigated; however, the prevalence of these problems in children with CD has not been suffici
Malignancies in patients with antineutrophil cytoplasmic antibody-associated vasculitis : A population-based cohort study
Objective. Patients with ANCA-associated vasculitides (AAV) exhibit higher rates of malignancy than the general population. We assessed whether the cancer risk is increased in a well-characterized population-based cohort of AAV in southern Sweden, followed for a median time of 8 years. Methods. With case record review, the outcomes and malignancy development in a cohort of 195 patients with AAV [g

Global Governance in Complex Times : Exploring New Concepts and Theories on Institutional Complexity
A theory-based approach to evaluations intended to inform transitions toward sustainability
There is an urgent need for radical transformations of unsustainable socio-technical systems, such as food, mobility, and housing. These transformations will not take place without new policies and research. In order to achieve these transitions, learning must be a central feature based on thorough evaluations of the actions taken. Evaluations have been conducted and studied for decades, but tradi
Lower 68Ga-DOTATOC uptake in nonfunctioning pituitary neuroendocrine tumours compared to normal pituitary gland—A proof-of-concept study
Objectives: 68Ga-DOTATOC PET targets somatostatin receptors (SSTRs) and is well established for the detection of SSTR-expressing tumors, such as gastrointestinal neuroendocrine tumors. Pituitary adenomas, recently designated as pituitary neuroendocrine tumors (PitNETs), also express SSTRs, but there has been no previous evaluations of 68Ga-DOTATOC PET in PitNET patients. The aim of this pilot stud
Expression, Purification and Initial Characterization of Functional α1-Microglobulin (A1M) in Nicotiana benthamiana
α1-Microglobulin (A1M) is a small glycoprotein that belongs to the lipocalin protein family. A major biological role of A1M is to protect cells and tissues against oxidative damage by clearing free heme and reactive oxygen species. Because of this, the protein has attracted great interest as a potential pharmaceutical candidate for treatment of acute kidney injury and preeclampsia. The aim of this
NG2/CSPG4, CD146/MCAM and VAP1/AOC3 are regulated by myocardin-related transcription factors in smooth muscle cells
The present work addressed the hypothesis that NG2/CSPG4, CD146/MCAM, and VAP1/AOC3 are target genes of myocardin-related transcription factors (MRTFs: myocardin/MYOCD, MRTF-A/MKL1, MRTF-B/MKL2) and serum response factor (SRF). Using a bioinformatics approach, we found that CSPG4, MCAM, and AOC3 correlate with MYOCD, MRTF-A/MKL1, and SRF across human tissues. No other transcription factor correlat
The pupil-size artefact (PSA) across time, viewing direction, and different eye trackers
The pupil size artefact (PSA) is the gaze deviation reported by an eye tracker during pupil size changes if the eye does not rotate. In the present study, we ask three questions: 1) how stable is the PSA over time, 2) does the PSA depend on properties of the eye tracker set up, and 3) does the PSA depend on the participants' viewing direction? We found that the PSA is very stable over time for per
Orthodontic appliances and MR image artefacts : An exploratory in vitro and in vivo study using 1.5-T and 3-T scanners
Purpose: The aim of this study was to assess the artefacts of 12 fixed orthodontic appliances in magnetic resonance images obtained using 1.5-T and 3-T scanners, and to evaluate different imaging sequences designed to suppress metal artefacts. Materials and Methods: In vitro, study casts of 1 adult with normal occlusion were used. Twelve orthodontic appliances were attached to the study casts and
The Swedish forestry model: intensifying production for sustainability
Sweden is often seen as a frontrunner when it comes to sustainability. For example, it has the highest share of renewable energy in the EU and is known for its thorough recycling and waste separation. Sweden is sparsely populated and 70% of its land area is covered by forests. Over the last century, the volume of yearly timber harvests has doubled, but despite this remarkable productivity increase
Intermittent chaotic chimeras for coupled rotators
Two symmetrically coupled populations of N oscillators with inertia m display chaotic solutions with broken symmetry similar to experimental observations with mechanical pendulums. In particular, we report evidence of intermittent chaotic chimeras, where one population is synchronized and the other jumps erratically between laminar and turbulent phases. These states have finite lifetimes diverging

A Distinctive Adnexal (Usually Paratubal) Neoplasm Often Associated with Peutz-Jeghers Syndrome and Characterized by STK11 Alterations (STK11 Adnexal Tumor) : A Report of 22 Cases
We describe 22 examples of a novel, usually paratubal, adnexal tumor associated with Peutz-Jeghers syndrome in nearly 50% of cases that harbored STK11 alterations in all tested (n=21). The patients ranged from 17 to 66 years (median=39 y) and the tumors from 4.5 to 25.5 cm (median=11 cm). Most (n=18) were paratubal, with metastases noted in 11/22 (50%) and recurrences in 12/15 (80%). Morphological
