A 55-year-old woman developed an airborne dermatitis on her face. Patch testing was performed and showed positive reactions to formaldehyde, thiuram mix, carba mix, and nickel sulphate. She operated a machine at work in which polyacetal granules were heated. The presence of formaldehyde in the pyrolysis smoke from the polymer was confirmed by chemical analysis.
The upper Middle to basal Upper Ordovician succession (Darriwilian to Sandbian) of the Fågelsång-3 drill core provides new important information on the graptolite biostratigraphy of Scania, southern Sweden. The Scanian succession is known largely from drill cores and a few scattered outcrops exposing only parts of the interval. The Darriwilian Almelund Shale Formation overlies the Komstad Limeston
Two men employed as painters and paperhangers showed a long-standing contact dermatitis of the hands and nummular eczema of the arms and legs. Patch testing using the standard series yielded a positive reaction to Kathon CG. Concomitant contact allergy to 1,2-benzisothiazolin-3-one was found in both patients. The occurrence of 1,2-benzisothiazolin-3-one was not declared on all of the paints to whi
Junior partners in a coalition government are torn between an eagerness to profile themselves, and to show loyalty to the coalition. We investigate when, how and why junior coalition parties affect foreign policy and profile themselves despite demands for national unity. We study two Swedish centre-right governments in 2006–2010 and 2010–2014. The parties' foreign policy positions in election mani
Substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP) coexist in nerve fibres in the skin. CGRP causes erythema upon intracutaneous injection. The erythema is independent of axon reflexes and release of mast cell histamine. SP is known to produce a flare reaction that is dependent on axon reflexes and release of mast cell histamine. The flare reaction to NKA is known to d
Proteins of the serpin family (serine protease inhibitor) control key steps in the inflammatory, coagulation and complement systems. C1‐inhibitor deficiency predisposes to hereditary angioneurotic oedema, and other serpins control proteolytic enzymes that may cause complement activation or the forming of oedema. We investigated whether deficiency of proteins of the serpin family may predispose to
Det var en begivenhedsrig uge, den Hollandske musikfestival November Music i år faldt sammen med. Trump havde netop vundet det amerikanske præsidentvalg, og verden viste sig at være andet end det mange af os troede, den var, da vi gik i seng den skæbnesvangre tirsdag aften. Begivenheden satte sig i min krop, som en oplevelse af, at den verden jeg kendte på overraskende vis nu var ved at gå i opløs
The actions and interactions of putative mediators of inflammation, such as substance P (SP), histamine, bradykinin and prostaglandins (PGE2) were studied in human skin. In addition, the effects of capsaicin were examined as it is known to release (and to deplete) SP and calcitonin gene-related peptide from C-fibres. The flare evoked by bradykinin was abolished by pretreatment with lignocaine (loc
Guinea pigs were sensitized to dinitrochlorobenzene (DNCB) by the intracutaneous route and challenged epicutaneously tin the flanks. The intensity of the allergic contact dermatitis was evaluated by inspection and palpation as well us by wet weight determination. With the purpose of diminishing tissue neuropeptides, and substance P in particular, the animals were treated with capsaicin either betw
The role of substance P (SP) in allergic reactions of the skin was investigated. Spantide, a competitive inhibitor of SP, was injected intracutaneously into the volar aspect of the forearm prior to the following challenges: benzalkonium chloride (irritant delayed reaction), tuberculin (immunological delayed reaction), UVB irradiation, benzoic acid (non-immunological contact urticaria), different f
Objective: To evaluate trends in bladder cancer incidence, survival and mortality in Sweden from 1997–2016. Patients and methods: The Swedish National Registry of Urinary Bladder Cancer is a nation-wide quality register that started in 1997. It includes information on initial tumor characteristics and treatment; 41,097 new cases were registered up to 2016. Patients were stratified into four time p
Chromium(Cr) poisoning of the traditional LSM cathode is one of the most critical issues that accounts for instability of solid oxide fuel cells (SOFCs). The poisoning course will introduce alien species in the cathode active regions and it causes phase change and structure deformation, reducing the sites for electrochemical reactions. A 3D model is thus developed by coupling the computational flu
Migranters röster om stadens historia. Malmö
Migraine is a prevalent disorder, affecting 15.1% of the world’s population. In most cases, the migraine attacks are sporadic; however, some individuals experience a gradual increase in attack frequency over time, and up to 2% of the general population develop chronic migraine. The mechanisms underlying this chronicity are unresolved but are hypothesized to involve a degree of inflammation. In thi
This study seeks to determine potential changes in the degree of openness in pharmaceutical R&D by investigating where the knowledge behind new molecular entities (NMEs) comes from in terms of type of organization, geography and time. We find that the organizations granted NMEs increasingly rely on external knowledge sources but that these are increasingly shared among NME grantees. Universiti
Systemic lupus erythematosus (SLE) is a common autoimmune disease. Recent findings have shown that a major single nucleotide variant predisposing to SLE is associated with low production of reactive oxygen species (ROS). A variant amino acid in a frequent NCF1 allele causing deficient ROS production leads to an exaggerated type I interferon (IFN) response, earlier disease onset, and higher suscept
Background and purpose — Patient-specific data on multiple total arthroplasties (TA) of the lower limbs due to osteoarthritis (OA) are limited. We investigated the sequence of surgical procedures and risk factors for additional surgery in such patients. Patients and methods — 305,996 patients operated with a TA of the hip and/or knee due to OA were extracted from the Swedish National Hip (SHAR) an
South African ball-rolling dung beetles exhibit a unique orientation behavior to avoid competition for food: after forming a piece of dung into a ball, they efficiently escape with it from the dung pile along a straight-line path. To keep track of their heading, these animals use celestial cues, such as the sun, as an orientation reference. Here we show that wind can also be used as a guiding cue
We investigated the impact on work life exits from reduced access to disability pension (2006), and financial incentives to extend working life. Method and materialWe used labour statistics of all employees in Sweden, Social insurance and income data, to compare occupational groups (SSYK, based on ISCO-88), and blue and white collar workers, with regard to i) lost years in working life due to deat
