Background: Methylisothiazolinone (MI) has caused an unprecedented epidemic of contact allergy in Europe and elsewhere. Subsequently, regulatory action has been taken, at least in Europe, aiming at reducing risk of MI sensitization. Objective: To follow-up on the prevalence of contact allergy to MI in consecutively patch tested patients and assess the spectrum of products containing MI or methylch

Som följd av den globala finanskrisen befinner sig nu Sverige i en djup ekonomisk kris – troligen den djupaste sedan 1930-talet. Det dystra läget har skapat ett intresse för kriser i vår historia. Lars Jonung diskuterar i denna artikel vad vi kan lära från tidigare finanskriser, vilken vägledning de ger oss beträffande dagens kris och vad de säger om framtiden.

Under lång tid var Ingemar Ståhl en välkänd nationalekonom i vårt land. Han presenterade nya perspektiv inom forskning, debatt och undervisning. På områ- den som bostäder, försvarsekonomi, energipolitik, finansiell ekonomi, industri- politik, högre utbildning, löntagarfonder, rättsekonomi, sjukvårdsekonomi och skatter lämnade han avtryck. Han förespråkade ett public choice-perspektiv, vilket han a

The role of developmental bias and plasticity in evolution is a central research interest in evolutionary biology. Studies of these concepts and related processes are usually conducted on extant systems and have seen limited investigation in the fossil record. Here, I identify plasticity-led evolution (PLE) as a form of developmental bias accessible through scrutiny of paleontological material. I

The Swedish steel industry stands before a potential transition to drastically lower its CO2 emissions using direct hydrogen reduction instead of continuing with coke-based blast furnaces. Previous studies have identified hydrogen direct reduction as a promising option. We build upon earlier efforts by performing a technological innovation system study to systematically examine the barriers to a t

Molecularly imprinted materials, prepared using self-assembly imprinting protocols using only non-covalent interactions, can be used as chromatography media in aqueous phase. The recognition properties are highly dependent on the interacting species used in the imprinting protocol. Ionic interactions, together with strong hydrogen bonding, represent useful means of obtaining recognition. With incr

Botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT) are the most potent toxins known and cause botulism and tetanus, respectively. BoNTs are also widely utilized as therapeutic toxins. They contain three functional domains responsible for receptor-binding, membrane translocation, and proteolytic cleavage of host proteins required for synaptic vesicle exocytosis. These toxins also have dist

We enrolled 427 human immunodeficiency virus-infected children (median age, 7.3 years), 59.2% severely immunodeficient, with suspected tuberculosis in Southeast Asian and African settings. Nontuberculous mycobacteria were isolated in 46 children (10.8%); 45.7% of isolates were Mycobacterium avium complex. Southeast Asian origin, age 5-9 years, and severe immunodeficiency were independently associa

In phase-change memory devices, a material is cycled between glassy and crystalline states. The highly temperature-dependent kinetics of its crystallization process enables application in memory technology, but the transition has not been resolved on an atomic scale. Using femtosecond x-ray diffraction and ab initio computer simulations, we determined the time-dependent pair-correlation function o

Aim: To increase understanding of the consequences of growing up with substance-abusing parents, including how this can influence the experience of becoming a parent. Methods: In-depth interviews were conducted with 19 parents who had participated in an Infant and Toddler Psychiatry Unit intervention programme and who had experienced substance-abusing parents in their family of origin. Directed qu

One important challenge of the wooden constructions is to achieve a high quality of acoustic insulation, especially decreasing the impact noise in the low-frequency range. In order to avoid over-designed solutions and expensive experimental tests in the design phase, reliable prediction tools are called for. This article is an initial investigation of modeling the ISO standardized tapping machine

Research on (verbo-) pictorial metaphors and other rhetorical figures is primarily focused on the genre of advertising, leaving other genres under-investigated. In this study, we focus on street art, a visually perceived cross-cultural medium used to address sociopolitical issues. This genre typically combines two interacting semiotic systems – language and depiction – and is thus a form of polyse

A brief pedagogical introduction to correlation femtoscopy is given. We then focus on the shape of the correlation function and discuss the possible reasons for its departure from the Gaussian form and better reproduction with a Lévy stable distribution. With the help of Monte Carlo simulations based on asymmetric extension of the Blast-Wave model with resonances we demonstrate possible influence

BACKGROUND/OBJECTIVES: Dementia and cognitive impairment are common in nursing homes. Few studies have studied the impact of unnoted cognitive impairment on medical care. This study aimed to estimate the prevalence of diagnostic failure of cognitive impairment in a sample of Swedish nursing home residents and to analyze whether diagnostic failure was associated with impaired medical care.METHOD: A

PURPOSE: NODDI (Neurite Orientation Dispersion and Density Imaging) and DTI (Diffusion tensor imaging) may be useful in identifying abnormal regions in patients with MRI-negative refractory epilepsy. The aim of this study was to determine whether NODDI and DTI maps including neurite density (ND), orientation dispersion index (ODI), mean diffusivity (MD) and fractional anisotropy (FA) can detect st
