Background: The Osborn or J-wave, an upright deflection of the J-point on the electrocardiogram (ECG), is often observed during severe hypothermia. A possible relation between Osborn waves (OW) and increased risk of ventricular arrhythmia has been reported. We sought to determine whether the level of targeted temperature management (TTM) following out-of-hospital cardiac arrest (OHCA) affects the
In addition to money or other compensation, other motives for selling sex may be important in a welfare country such as Sweden. The aim of this study was to carry out an exploratory investigation of adolescents’ motives for selling sex in a population-based survey in Sweden. A total of 5839 adolescents from the third year of Swedish high school, mean age 18.0 years, participated in the study. The
Apolipoprotein M (ApoM) is a sphingosine 1-phosphate (S1P) carrier involved in the regulation of S1P. Signaling pathways involving sphingosine kinases (SphKs) and S1P-S1P receptors (S1PRs) play important roles in the oncogenesis of multiple cancers including non-small cell lung cancer (NSCLC). In the present study we have clarified the potential roles of ApoM on the oncogenesis process of NSCLC ce
The antenna is the main sensory organ of insects, housing different types of sensilla dedicated to detect chemicalcues, motion, humidity and temperature. Sensilla are divided into different types based on their wall structureand morphology. Among the olfactory sensilla, there is an enormous variation in the numbers and morphologicaltypes present in different insect taxa. The reasons for this varia
Flotation is a unit operation extensively used in the recovery of valuable minerals in mineral processing and related applications. Essential insight to the hydrodynamics of a otation column can be obtained by studying just two phases: gas and uid. To this end, the approach based on the drift-flx theory, proposed in similar form by several authors, is reformulated as a one-dimensional non-linear c
Vertical nanowire n-type (InAs) and p-type (GaSb) transistors are co-processed and co-integrated using a gate-last process, enabling short gate-lengths (Lg=40 nm) and allowing selective digital etching of the channel. Two different common gate-stacks, including various pre-treatments, were compared and evaluated. The process was optimized to achieve high n-type performance while demonstrating
Background: Both lifestyle and genetic predisposition determine the development of type 2 diabetes (T2D), and studies have indicated interactions between specific dietary components and individual genetic variants. However, it is unclear whether the importance of overall dietary habits, including T2D-related food intakes, differs depending on genetic predisposition to T2D. We examined interaction
Background: Early initiation of breastfeeding (EIBF) lowers the risk for all-cause mortality in babies, including those with low birth weight. However, rates of neonatal mortality and delayed initiation of breastfeeding remain high in most low- and middle-income countries. This study aimed to assess the trends and factors associated with EIBF in Namibia from 2000 to 2013. Methods: An analysis of E
Many features of the development of reptiles are affected by temperature, but very little is known about how incubation temperature affects gene expression. Here, we provide a detailed case study of gene expression profiles in common wall lizard (Podarcis muralis) embryos developing at stressfully low (15°C) versus benign (24°C) temperature. For maximum comparability between the two temperature re
Background: The unanticipated difficult airway is a potentially life-threatening event during anaesthesia or acute conditions. An unsuccessfully managed upper airway is associated with serious morbidity and mortality. Several bedside screening tests are used in clinical practice to identify those at high risk of difficult airway. Their accuracy and benefit however, remains unclear. Objectives: The
Regression trees are evaluated with respect to mean square error (MSE), mean integrated square error (MISE), and integrated squared error (ISE), as the size of the training sample goes to infinity. The asymptotically MSE- and MISE minimizing (locally adaptive) regression trees are characterized. Under an optimal tree, MSE is O(n^{-2/3}). The estimator is shown to be asymptotically normally distrib
Streptococcus pyogenes is an exclusively human pathogen that can provoke mild skin and throat infections but can also cause fatal septicemia. This gram-positive bacterium has developed several strategies to evade the human immune system, enabling S. pyogenes to survive in the host. These strategies include recruiting several human plasma proteins, such as the complement inhibitor, C4b-binding prot
Several studies have shown that time domain reflectometry (TDR) can be used to measure water content and solute concentration during steady-state experiments with constant soil water content. Few studies have been carried out to identify the relationship between bulk electrical conductivity (σa) and soil solution electrical conductivity (σw) to be used for transient conditions with varying water c
Phosphorylcholine (PC) is an epitope on oxidized low-density lipoprotein (oxLDL), apoptotic cells and several pathogens like Streptococcus pneumoniae. Immunoglobulin M against PC (IgM anti-PC) has the ability to inhibit uptake of oxLDL by macrophages and increase clearance of apoptotic cells. From our genome-wide association studies (GWASs) in four Europeanancestry cohorts, six single nucleotide p
We experimentally explore the role of collective incentives in sustaining cooperation in finitely repeated public goods games with imperfect monitoring. In our experiment players only observe noisy signals about individual contributions, while total output is perfectly observed. We consider sanctioning mechanisms that allow agents to commit to collective punishment in case total output fall short
Although Singapore, a linguistically and ethnically diverse city–state, uses four official languages, namely Malay, Mandarin, Tamil, and English, which are supposed to enjoy equal status, there appears to be a pecking order to these languages. English seems to be the dominant language when taking into consideration the bilingual education policy, numerous campaigns promoting its use in terms of sp
Rye kernel bread (RKB) evening meals improve glucose tolerance, enhance appetite regulation and increase satiety in healthy volunteers. These beneficial effects on metabolic responses have been shown to be associated with increased gut fermentation. The present study aimed to elucidate if RKB evening meals may cause rapid alterations in microbiota composition that might be linked to metabolic-, im
Pedagogik är en av de klassiska vetenskapliga disciplinerna och har som universitetsämne en hundraårig tradition. I takt med att samhället förändras har även det innehåll som sysselsätter pedagogiken ändrats. Var befinner sig det vetenskapliga ämnet pedagogik i dag? Hur ser den historiska bakgrunden till ämnets framväxt ut? Vilka är de fundament som håller samman pedagogikämnet? Vilka framtida utm
