Combined U-Pb, O and Hf isotope data in zircon allows discrimination between juvenile and reworked crust, and is therefore a useful tool for understanding formation and evolution of the continental crust. The crustal evolution of basement rocks in central North America (Laurentia) is poorly constrained, as it is almost entirely overlain by Palaeozoic cover. In order to improve our understanding of
The aim of this study was to evaluate tracking performance when an extra reference block is added to a basic block-matching method, where the two reference blocks originate from two consecutive ultrasound frames. The use of an extra reference block was evaluated for two putative benefits: (i) an increase in tracking performance while maintaining the size of the reference blocks, evaluated using in
GOALS:: To compare the clinical outcomes of gastroesophageal reflux disease (GERD) patients treated with an implemented new structured pathway (NSP) or according to existing local clinical practices [old clinical pathway (OCP)]. BACKGROUND:: GERD is a major challenge at the primary care level. STUDY:: Primary care centers (n=24) were cluster randomized to handle patients suffering from symptoms su
Contagious yawning is a well-documented phenomenon in humans and has recently attracted much attention from developmental and comparative sciences. The function, development and underlying mechanisms of the phenomenon, however, remain largely unclear. Contagious yawning has been demonstrated in dogs and several non-human primate species, and theoretically and empirically associated with empathy in
The sensitivity of the process parameters of the Biosphere Energy Transfer HYdrology (BETHY) model to choices of atmospheric concentration network, high frequency terrestrial fluxes, and the choice of flux measurement network is investigated by using a carbon cycle data assimilation system. We use BETHY-generated fluxes as a proxy of flux measurements. Results show that monthly mean or low-frequen
In-situ wide-angle X-ray scattering (WAXS) measurements have been conducted on atmosphericpressure fuel-rich premixed freely propagating ethylene/oxygen flames with argon and nitrogen dilution. In this work, a novel analysis methodology able to provide quantitative information on soot/carbon particle species and concentrations was tested under heavy sooting conditions. The particle composition and
Reactions in aqueous solution under hydrothermal conditions between (+/-)-2,3-dimethylsuccinic acid and lanthanide chlorides lead to two different isostructural types with chemical formulas [Ln(2)(C6H8O4)(3)(H2O)(2)] Ln(III) = Pr-Eu (except Pm) (Type I, compounds 1-4) and [Ln(2)(C6H8O4)(3)] Ln(III) = Tb-Yb (except Tm) (Type II, compounds 5-9). The crystal structure has been solved for the Pr (1)-,
Previous genome-wide association (GWA) studies have identified SNPs associated with areal bone mineral density (aBMD). However, this measure is influenced by several different skeletal parameters, such as periosteal expansion, cortical bone mineral density (BMDC) cortical thickness, trabecular number, and trabecular thickness, which may be under distinct biological and genetic control. We have car
Background: Sickness absence has represented a growing public health problem in many Western countries over the last decade. In Sweden disorders of the musculoskeletal system cause approximately one third of all sick leave. The Social Insurance Agency (SIA) and the health care system are important actors in handling the sickness absence process. The objective was to study how patients with persona
The reliability of the newly constructed Moral Attitude Questionnaire (MAQ) was tested in this Pilot study. MAQ aims to assess individual and cultural differences in moral attitudes and expected behavior on a broad scale, contrasting typically consequentialistic attitudes with typically non-consequentialistic attitudes congruent with common-sense moral. Five representative categories with five sto
Background: The aim of this study is to analyze longitudinally, based on four measurements at intervals of eight years, the annual effect of age group and birth cohort on regular exercise in the Swedish population from 1980-1981 to 2004-2005. Methods: We followed a randomly drawn subsample of individuals aged 16-63 years, interviewed by professional interviewers, from the Swedish Annual Level of L
Empirical research about late sexual debut and its consequences is limited, and further research is needed.
Few epidemiological studies have examined the association between dietary trans fatty acids and weight gain, and the evidence remains inconsistent. The main objective of the study was to investigate the prospective association between biomarker of industrial trans fatty acids and change in weight within the large study European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.
The major histcompatibility complex (MHC) is a vital component of the adaptive immune system in all vertebrates. This study is the first to characterize MHC class I (MHC-I) in blue tits (Cyanistes caeruleus), and we use MHC-I exon 3 sequence data from individuals originating from three locations across Europe: Spain, the Netherlands to Sweden. Our phylogeny of the 17 blue tit MHC-I alleles contain
Background: In mental health care practice and research it is increasingly recognized that clients' subjective perceptions of everyday occupations, such as satisfaction, are important in recovery from mental illness. Instruments thus need to be developed to assess satisfaction with everyday occupations. The aim of the present study was to assess psychometric properties of the 13-item Satisfaction
Treatment in medical oncology is gradually shifting from the use of nonspecific chemotherapeutic agents toward an era of novel targeted therapy in which drugs and their combinations target specific aspects of the biology of tumor cells. Multiple myeloma (MM) has become one of the best examples in this regard, reflected in the identification of new pathogenic mechanisms, together with the developme
OBJECTIVE-Phosphoinositide 3-kinase (PI3K) is a major effector in insulin signaling. rs361072, located in the promoter of the gene (PIK3CB) for the p110 beta subunit, has previously been found to be associated with homeostasis model assessment for insulin resistance (HOMA-IR) in obese subjects. The aim was to investigate the influence of rs361072 on in vivo glucose metabolism, skeletal muscle PI3K
Comparing patterns of diversity and divergence between populations at immune genes and neutral markers can give insights into the nature and geographic scale of parasite-mediated selection. To date, studies investigating such patterns of selection in vertebrates have primarily focused on the acquired branch of the immune system, whereas it remains largely unknown how parasite-mediated selection sh
