A new case of photoallergic contact dermatitis caused by benzophenones in magazine covers

Background: Allergic contact dermatitis (ACD) and photoallergic contact dermatitis (PACD) to benzophenone present in printing ink have been reported. However, precise chemical analyses and extended photo-patch tests have not been performed in these cases. Objectives: To determine which components present in a magazine cover are responsible for a patient's skin reaction, to determine the primary se

Anisotropic diffusion of ellipsoidal tracers in microswimmer suspensions

Tracer particles immersed in suspensions of biological microswimmers such as E. coli or C. reinhardtii display phenomena unseen in conventional equilibrium systems, including strongly enhanced diffusivity relative to the Brownian value and non-Gaussian displacement statistics. In dilute, three-dimensional suspensions, these phenomena have typically been explained by the hydrodynamic advection of p

International trade and labour market integration of immigrants

We examine whether international trade improves labour market integration of immigrants in Sweden. Immigrants participate substantially less than natives in the labour market. However, trading with a foreign country is expected to increase the demand for immigrants from that country. By hiring immigrants, a firm may access foreign knowledge and networks needed to overcome information frictions in

Four Swedish cases of CSF1R-related leukoencephalopathy : Visualization of clinical phenotypes

Colony stimulating factor 1 receptor (CSF1R)-related leukoencephalopathy is a rare, genetic disease caused by heterozygous mutations in the CSF1R gene with rapidly progressive neurodegeneration, behavioral, cognitive, motor disturbances. Objective: To describe four cases of CSF1R-related leukoencephalopathy from three families with two different pathogenic mutations in the tyrosine kinase domain o

Development of dosimetric procedures for experimental ultra-high dose rate irradiation at a clinical linear accelerator

As radiotherapy using ultra-high dose rates has gained new interest, the dosimetric challenges arising at these conditions needs to be addressed. Ionization chambers suffer from a large decrease in ion collection efficiency due to ion recombination, making on-line dosimetry difficult. In this work we present experimental setups and dosimetric procedures for FLASH irradiation of cells, zebrafish em

Drivers of Going Green in Financial Markets and Corporate Networks

This dissertation is a collection of three self-contained empirical papers developing the knowledge on environmental responsibility of investors and corporations.The first paper investigates how corporate environmental performance propagates in firm networks. We find that the degree of spillover depends on the type of link between firms as well as their relative strength in the network. The effect

An Output-Sensitive Algorithm for All-Pairs Shortest Paths in Directed Acyclic Graphs

First, we present a new algorithm for the single-source shortest paths problem (SSSP) in edge-weighted directed graphs, with n vertices, m edges, and both positive and negative real edge weights. Given a positive integer parameter t, in O(tm) time the algorithm finds for each vertex v a path distance from the source to v not exceeding that yielded by the shortest path from the source to v among th

Editorial: developments at the Annals of regional science 2020–2021

The editors-in-chief of the Annals of Regional Science offer an overview and analysis of recent developments at the journal from January 2020 through December 2021, a time period hampered by the COVID-19 pandemic. Annal’s Impact Factor increased substantially to 2.646 in 2020. Moreover, submissions increased from pre-COVID times. A new development is the shifting of source regions for articles acc

Galectin-3 ablation does not affect infarct size or inflammatory cytokines after experimental stroke in 24-month-old female mice

Background: The tissue damage following a focal stroke causes an inflammatory response that is thought to aggravate the disease state. Galectin-3 is a proinflammatory molecule that has been shown to play a significant role in the inflammatory responses in brain diseases and following experimental stroke. In most animal experiments, young animals are used, although attempts are often made to model

Endovascular thrombectomy for acute ischemic stroke

This review describes the evolution of endovascular treatment for acute ischemic stroke, current state of the art, and the challenges for the next decade. The rapid development of endovascular thrombectomy (EVT), from the first attempts into standard of care on a global scale, is one of the major achievements in modern medicine. It was possible thanks to the establishment of a scientific framework

New Insights in the Control of Fat Homeostasis : The Role of Neurotensin

Neurotensin (NT) is a small peptide with pleiotropic functions, exerting its primary actions by controlling food intake and energy balance. The first evidence of an involvement of NT in metabolism came from studies on the central nervous system and brain circuits, where NT acts as a neurotransmitter, producing different effects in relation to the specific region involved. Moreover, newer interesti

RIFM fragrance ingredient safety assessment, 4-(2,6,6-trimethyl-2-cyclohexen)-2-methylbutanal, CAS Registry Number 65405-84-7

The existing information supports the use of this material as described in this safety assessment. 4-(2,6,6-Trimethyl-2-cyclohexen)-2-methylbutanal was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that 4-(2,6,6-trimethyl-2-cyclohexen)-2-methylbutanal i
