Direction of galvanically-induced vestibulo-postural responses during active and passive neck torsion
The direction of a postural response induced by galvanic vestibular stimulation depends on the head and trunk position. The relative importance of afferent information (proprioception) and efferent motor command/corollary discharge is unknown. We studied the direction of body sway evoked by galvanic vestibular stimulation in 9 healthy subjects during active and passive head positioning at 0 degree

Atrial fibrillatory rate and sinus rhythm maintenance in patients undergoing cardioversion of persistent atrial fibrillation.
The study set out to explore whether an index of atrial electrical electrophysiology can be used to predict atrial fibrillation (AF) relapse, and if the predictive properties differ as a result of arrhythmia duration. METHODS AND RESULTS: The study comprised 175 consecutive patients with persistent AF (median duration 94 days, range 2 to 1044) referred for cardioversion. Twenty-nine patients had a
Calculated optoelectronic properties of ruthenium tris-bipyridine dyes containing oligophenyleneethynylene rigid rod linkers in different chemical environments
Ruthenium tris-bipyridine dyes containing oligophenyleneethynylene (OPE) rigid rod linker groups ([Ru(bpy)(3)](2+), [Ru(bpy)(2)bpy-E-Ipa](2+), [Ru(bpy)(2)bpy-E-Ph-E-Ipa](2+), and [Ru(bpy)(2)bpy-E-Bco-E-Ipa](2+), where bpy = 2,2'-bipyridine, E = ethynylene, Ph = p-phenylene, Bco = bicyclo[2.2.2]octylene, and Ipa = isophthalic acid) have been investigated using DFT and TD-DFT calculations to elucida

Prospective, longitudinal quality-of-life study of patients with head and neck cancer: a feasibility study including the EORTC QLQ-C30
Despite modern advances in the treatment of head and neck cancer, the survival rate fails to improve. Considering the different treatment modalities involved, quality of life has been thought of as an additional end point criterion for use in clinical trials. A Nordic protocol to measure the quality of life of head and neck cancer patients before, during, and after treatment was established. Befor
Arbetssituation och stresshantering hos kabinpersonal
Allvarliga tillbud och olyckor inom flygtrafiken är relativt ovanligt, men när de inträffar ställs höga krav på kabinpersonalens förmåga att uppträda auktoritativt och effektivt. Det är dock inte bara vid ett direkt olyckstillbud det ställs stora krav på kabinpersonalens förmåga att hantera kritiska situationer. Det finns en hel flora av incidenter som kräver professionell hantering, t ex när passAlthough serious accidents or near-accidents are relatively rare in airline traffic, when they occur cabin attendants are expected to act effectively and with authority. However, the ability of cabin attendants to intervene professionally is also called for in other critical situations, such as when incidents that are frightening for the passengers occur or when passengers suddenly become ill. The
Efficient modelling necessitates standards for model documentation and exchange
In this paper, problems related to simulation model documentation and model exchange between users are discussed. Complex simulation models have gained popularity in the environmental field, but require extensive documentation to allow independent implementation. The existence of different simulation platforms puts high demands on the quality of the original documentation. Recent experiences from
Biomassebaserade energibärare för transportsektorn
Det finns en stor potential för ett ökat utnyttjande av biomassa för energiändamål i Sverige. En ökad användning av biomassa skulle kunna bidra till att minska utsläppen av koldioxid från förbränning av fossila bränslen, minska beroendet av importerade fossila energibärare samt påverka den regionala och lokala miljösituationen såväl positivt som negativt. Föreliggande studie behandlar framför alltThere is a large potential for increasing the use of biomass for energy purposes in Sweden. Increasing the use of biomass can reduce emissions of carbon dioxide (CO2) from fossil-fuel combustion and dependence on imported fossil fuels. Furthermore, increased biomass use will affect emissions of other air pollutants than carbon dioxide as well as environmental impacts from land use. The study deals
A human cell surface receptor activated by free fatty acids and thiazolidinedione drugs.
Fatty acids, which are essential nutritional components, are also involved in cardiovascular and metabolic diseases. Here we report a human cell surface receptor that we name free fatty acid receptor (FFAR), because it is specifically activated by medium to long-chain free fatty acids. The receptor belongs to the class of seven-transmembrane, G-protein coupled receptors (GPCRs) and also mediates r

Simuleringar och analys av V. Cholerae odling där feeden styrs genom återkoppling från ättiksyramätningar
På Linköpings tekniska högskola har man tillgång till många olika sätt att mäta ättiksyra i en bioreaktor. Utrustningen för att mäta ättiksyra består av en NIR (near infrared spectroscopy) som mäter online och en samplingstid på sekund nivå kan uppnås. HPLC (high-performance liquid chromatography) finns det också tillgång till. Där räknar man med att ta prover var 15 min och att själva analysen ta
c-Myc antisense oligonucleotides preserve smooth muscle differentiation and reduce negative remodelling following rat carotid arteriotomy
Objectives: The vascular biology of restenosis is complex and not fully understood, thus explaining the lack of effective therapy for its prevention in clinical settings. The role of c-Myc in arteriotomy-induced stenosis, smooth muscle cell (SMC) differentiation and apoptosis was investigated in rat carotids applying full phosphorothioate antisense ( AS) oligonucleotides (ODNs). Methods: Carotid a
Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT
Popular Abstract in Swedish En hjärtinfarkt, dvs död hjärtmuskel, uppstår då en del av hjärtats muskel inte blodförsörjs, exempelvis genom att en propp bildats i ett av hjärtats blodkärl. Detta tillstånd bör behandlas snarast möjligt för att rädda största möjliga del av hjärtmuskeln, eftersom en större infarkt innebär sämre pumpfunktion vilket ger patienten sämre prognos. Tidsförloppet för en hjärThe effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. We therefore used DE-MRI to investigate how duration of ischaemia affects final infarct size normalized
Phase equilibria of model milk membrane lipid systems.
The phase behaviour of mixtures of recombined milk membrane lipids dioleoylphosphatidylcholine (DOPC), sphingomyelin (SM), dioleoylphosphatidylethanolamine (DOPE), phosphatidylinositol (PI) and dioleoylphosphatidylserine (DOPS) in 60% water was examined as a function of temperature between 5 and 90 °C. The aim was to examine under which lipid composition the average properties turn from balanced o
Prevalence of obstructive lung diseases and respiratory symptoms in southern Sweden
The prevalence of obstructive lung diseases is increasing in Scandinavia and worldwide. The reasons for this are not known. The prevalence varies between countries but also between different areas within the same country. In northern Europe a north-south gradient and also an east-west gradient have been proposed. To our knowledge this is the first comprehensive epidemiological study concerning obs
