Objectives Sustained activity of the upper trapezius muscle during work has been linked to the development of neck pain. Women have higher occurrences of neck pain than men, even in the same occupations. This study aimed to investigate sex-specific associations between upper trapezius muscle activity time-related variables and neck pain using a meta-analysis of pooled data. Methods Seven Scandinav
Very-low-field MRI (<100 mT) holds promise for Point-of-Care brain imaging applications, including stroke and multiple sclerosis, with T1 mapping emerging as a key biomarker for brain development and pathology. However, current low-field T1 mapping protocols suffer from long acquisition times and limited multi-site repeatability. This study aimed to improve T1 mapping at 64 mT using a clinically f
Membrane technology has revolutionized protein recovery in the food industry, beginning with whey protein extraction via ultrafiltration. This success led to its application in concentrating animal proteins like blood plasma, fish proteins, and albumen. As the protein shift towards plant-based sources grows, membrane processes now enable the industrial recovery of wheat, sunflower, and rapeseed pr
Popular Abstract in Swedish Många växtarter kan inte kolonisera kalkjordar och det är stora skillnader i artsammansättningen mellan kalkjordar och närliggande surare jordar. Detta beteende kallas ofta för kalkskyende och tycks orsakas av en oförmåga hos dessa växtarter att lösa och ta upp fosfat och järn ur kalkjordar. Kalkjordar innehåller mycket låga halter av järn och fosfat löst i marklösningeMany vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils. Differences between calc
The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mission is to repeatedly obtain high-precision astrometric and photometric measurements of one thousand million stars over the course of five years. The scientific value of the down-linked data, and the operation of the on
The ECL cells in the oxyntic mucosa secrete histamine in response to gastrin, stimulating parietal cells to produce acid. Do they also operate under nervous control? The present study examines histamine mobilization from rat stomach ECL cells in situ in response to acute vagal excitation and to food or gastrin following vagal or sympathetic denervation. Applying the technique of microdialysis, we
Popular Abstract in Swedish Den molekylära processen under vilken DNA-information förs över till RNA-information kallas transkription. Transkription styrs främst i samverkan med många speciella molekyler som kallas transkriptionsfaktorer. Zinkfinger proteiner är en av de vanligast förekommande klasserna av reglerande proteiner i eukaryota celler där de inverkar på en mängd av cellulära aktiviteterThe molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. A classical zinc finger is a small protein motif with a simple
Popular Abstract in Swedish Denna avhandling är uppbyggd kring fyra artiklar som berör reglering av gener i B-celler. B-cellerna är en viktig del av vårt immunförsvar, de sköter produktionen av antikroppar som hjälper till att skydda våra slemhinnor och vårt inre från sjukdomsframkallande bakterier och virus. Kroppens försvar mot sådana patogener består av flera delar, inklusive vår hud och våra sEach Ig V-region has its own upstream promoter and the promoter of a mature Ig gene is thereby selected during the V(D)J recombination process. Upon comparison, it is evident that only one transcription factor binding site, the octamer, is preserved within all promoters. The octamer motif and the binding Oct-proteins are crucial for Ig promoter function, but not sufficient for a high level of tran
The word “desertification” was introduced in 1949 by the French scientist Aubreville in his report “Climats, forêts et désertification de l´Afrique tropicale”. The concept, however, was discussed earlier by European and American scientists in terms of increased sand movements, desiccation, desert and Sahara encroachment and man made deserts. Desertification, at the beginning of last century, mea
This study argues that Vietnamese girls' socialization is inseparable from the symbolic and biological meaning of female and male bodies. Socialization is not so much about "sex" (i.e. biological sex) or "gender" (i.e. social/symbolic sex) as it is about "body". This argument is elaborated theoretically with regard to contemporary research on the body and empirically with respect to a local north
Popular Abstract in Swedish Skadeståndsrätten innehåller alternativa definitioner på culpa. Den innehåller tre Konkurrerande culpakriterier. Enligt normalitetskriteriet föreligger culpa om den som orsakat en skada inte har vidtagit de försiktighetsåtgärder som en normalt aktsam person hade vidtagit i motsvarande situation. Enligt det ekonomiska kriteriet föreligger culpa om skadan hade kunnat förhThe concept of negligence in tort law can be defined in (at least) three different ways. Negligence can be defined in terms of normality, i.e. as failing to act in accordance with custom or failing to meet the level of care taken by normally careful citizens. It can be defined in terms of efficiency. In that case it would mean refraining from taking a precaution that costs less to take than it sav
Two quasi steady-state solute transport experiments were carried out in a loamy sand under field conditions. The flux was 40 mm/d in experiment I and 18.7 mm/d in experiment 2. Both water content (theta) and resident concentration (C-r) measurements were taken using 64 time domain reflectometry probes at depths ranging from 0.05 to 0.90 m. The C-r measurement was calibrated in situ for each probe
Abnormalities in nuclear morphology are frequently observed in malignant tissues but the mechanisms behind these phenomena are still poorly understood. In this study, the relation between abnormal nuclear shape and chromosomal instability was explored in short-term tumor cell cultures. Mitotically unstable ring and dicentric chromosomes were identified by fluorescence in situ hybridization at meta
Stored-product moths cause large economic damage in food-processing industries and storage facilities. Control of indoor pests is currently dealt with locally, and control strategies seldom include different mills or cooperative industries in joint efforts to reduce infestations. In colder climates where conditions hinder flight dispersal of stored-product moths, we hypothesize that human transpor
Helicobacter pylori infection is associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma and MALT lymphoma. We previously found high-grade lymphoma after 13 months' H. pylori infection in C57BL/6 mice. In this study we followed H. pylori infection by three different isolates in C57BL/6 and Balb/cA mice for 23 months. Six-week-old C57BL/6 and Balb/cA mice were infected with
Stratigraphical relationships, facies and petrographical evidences define a rocky shoreline in the Late Wenlock of Gotland. The major facies-elements forming the rocky shoreline are 1) several subaerially exposed reefs, which were eroded during falling base-level and which form the topography, and 2), onlap of oolite grainstones which were deposited during the subsequent rise of the base-level. Fi
Aims: This study looked at whether oral desmopressin, by decreasing kidney urine production, would prolong bladder filling-time thereby increasing the time to reach maximum capacity, thus reducing overactive bladder (OAB) symptoms, and providing an alternative method of treatment to OAB sufferers. Methods: An investigator-initiated, 2-week, multi-national, multi-centre, "proof-of-concept," phase I
The pathogenic yersiniae inject proteins directly into eukaryotic cells that interfere with a number of cellular processes including phagocytosis and inflammatory-associated host responses. One of these injected proteins, the Yersinia protein kinase A (YpkA), has previously been shown to affect the morphology of cultured eukaryotic cells as well as to localize to the plasma membrane following its
Shikimic acid is one of several industrially interesting chiral starting materials formed in the aromatic amino acid pathway of plants and microorganisms. In this study, the physiology of a shikimic acid producing strain of Escherichia coli (derived from W31 10) deleted in aroL (shikimic acid kinase II gene), was compared to that of a corresponding control strain W31 10) under carbonand phosphate-
