Interactions between tachykinins and CGRP in human skin

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

Heterozygous, a1-antitrypsin deficiency may be associated with cold urticaria.

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

Effects of capsaicin, bradykinin and prostaglandin E2 in the human skin

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

Capsaicin enhances allergic contact dermatitis in guinea pig.

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

Substance P antagonist inhibits immediate and delayed type cutaneous hypersensitivity reactions.

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

Incidence, survival and mortality trends of bladder cancer in Sweden 1997–2016

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

Thermal stress analysis of solid oxide fuel cells with chromium poisoning cathodes

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

Does inflammation have a role in migraine?

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

Potential effects of increased openness in pharma : the original knowledge behind new drugs

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

Low Production of Reactive Oxygen Species Drives Systemic Lupus Erythematosus

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

Sequence of 305,996 total hip and knee arthroplasties in patients undergoing operations on more than 1 joint

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

Multimodal cue integration in the dung beetle compass

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

National policies and social inequalities in exit paths from working life in Sweden

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

Night and Organization Studies

In this essay, I want to shed light on the phenomena of night and nightwork as important topics which have been so far overlooked in organization studies. Inspired by insights of new materialism (Barad), I propose and investigate night as ‘time-space’, and present intertwined dimensions (temporal, spatial, social, material, etc.) of intra-actions between human beings and night. To better understan

Factors related to health-related quality of life in older people with multimorbidity and high health care consumption over a two-year period

BACKGROUND: The prevalence of multimorbidity is increasing worldwide, and older people with multimorbidity are frequent users of health care services. Since multimorbidity has a significant negative impact on Health-related Quality of Life (HrQoL) and is more common in older age it would be expected that factors related to HrQoL in this group might have been thoroughly researched, but this is not
