Low preparedness before the loss of a wife to cancer and the widower's chronic pain 4-5 years later-a population-based study
ObjectiveThe focus of this study was on the impact of spousal loss on the development of chronic pain thereafter. More specifically, the aim was to investigate the effect of experiencing low preparedness before a wife's death and the widower's chronic pain 4-5 years after loss. MethodsIn a population-based study in the years 2004-2005, anonymous questionnaires were sent out to 907 men in Sweden wh
Nitinol versus steel partially covered self-expandable metal stent for malignant distal biliary obstruction: a randomized trial.
Covered nitinol alloy self-expandable metal stents (SEMSs) have been developed to overcome the shortcomings of steel SEMS in patients with malignant biliary obstruction. In a randomized, multicenter trial, we compared stent patency, patient survival, and adverse events in patients with partly covered stents made from steel or nitinol.
Source localization of rhythmic ictal EEG activity: A study of diagnostic accuracy following STARD criteria
PurposeAlthough precise identification of the seizure-onset zone is an essential element of presurgical evaluation, source localization of ictal electroencephalography (EEG) signals has received little attention. The aim of our study was to estimate the accuracy of source localization of rhythmic ictal EEG activity using a distributed source model. MethodsSource localization of rhythmic ictal scal
Flow of energy in the outer retina in darkness and in light
Structural features of neurons create challenges for effective production and distribution of essential metabolic energy. We investigated how metabolic energy is distributed between cellular compartments in photoreceptors. In avascular retinas, aerobic production of energy occurs only in mitochondria that are located centrally within the photoreceptor. Our findings indicate that metabolic energy f
Behaviour of nonsteroidal anti-inflammatory drugs and eight of their metabolites during wastewater treatment studied by hollow fibre liquid phase microextraction and liquid chromatography mass spectrometry.
In this work hollow fibre liquid phase microextraction combined with liquid chromatography mass spectrometry was applied for the determination of the nonsteroidal anti-inflammatory drugs (NSAIDs) ketoprofen, naproxen, diclofenac and ibuprofen as well as eight of their known human metabolites in wastewater samples. Extraction time and addition of tri-n-octylphosphine oxide (TOPO) to the liquid memb
Low androstenedione/sex hormone binding globulin ratio increases fracture risk in postmenopausal women. The Women's Health in the Lund Area study.
The Women's Health in the Lund Area (WHILA) project (n=6917) is a cohort study that started in 1995 and includes a postal questionnaire, physical examination, bone density measurement and blood laboratory analyses. Fracture data have been added, and in this report fracture risk and its association with sex hormones was analysed in postmenopausal women without current hormone therapy (HT). A total
Hundreds of variants clustered in genomic loci and biological pathways affect human height
Most common human traits and diseases have a polygenic pattern of inheritance: DNA sequence variants at many genetic loci influence the phenotype. Genome-wide association (GWA) studies have identified more than 600 variants associated with human traits(1), but these typically explain small fractions of phenotypic variation, raising questions about the use of further studies. Here, using 183,727 in
Dissatisfied patients after total knee arthroplasty.
Background and purpose - In 2003, an enquiry by the Swedish Knee Arthroplasty Register (SKAR) 2-7 years after total knee arthroplasty (TKA) revealed patients who were dissatisfied with the outcome of their surgery but who had not been revised. 6 years later, we examined the dissatisfied patients in one Swedish county and a matched group of very satisfied patients. Patients and methods - 118 TKAs i
Heparin-binding protein (HBP) in critically ill patients with influenza A (H1N1) infection
Heparin-binding protein (HBP) is an inducer of vascular endothelial leakage in severe infections. Fluid accumulation into alveoli is a general finding in acute respiratory distress syndrome (ARDS). Severe acute respiratory failure with ARDS is a complication of influenza A(H1N1) infection. Accordingly, we studied the HBP levels in critically ill patients with infection of influenza A(H1N1).Critica
School bullying and the mechanisms of moral disengagement
The aim of the present study was to examine to what degree different mechanisms of moral disengagement were related to age, gender, bullying, and defending among school children. Three hundred and seventy-two Swedish children ranging in age from 10 to 14 years completed a questionnaire. Findings revealed that boys expressed significantly higher levels of moral justification, euphemistic labeling,
Effects on healthcare utilization of case management for frail older people: A randomized controlled trial (RCT).
Various healthcare interventions have been launched targeting the growing population of older people. The objective of this study was to investigate the of a case management intervention for frail old people (aged 65+ years) effects on healthcare utilization.
Brain Resuscitation in the Drowning Victim
Drowning is a leading cause of accidental death. Survivors may sustain severe neurologic morbidity. There is negligible research specific to brain injury in drowning making current clinical management non-specific to this disorder. This review represents an evidence-based consensus effort to provide recommendations for management and investigation of the drowning victim. Epidemiology, brain-orient
Reductive evolution of proteomes and protein structures
The lengths of orthologous protein families in Eukarya are almost double the lengths found in Bacteria and Archaea. Here we examine protein structures in 745 genomes and show that protein length differences between superkingdoms arise as much shorter prokaryotic nondomain linker sequences. Eukaryotic, bacterial, and archaeal linkers are 250, 86, and 73 aa residues in length, respectively, whereas
First passage times for a tracer particle in single file diffusion and fractional Brownian motion.
We investigate the full functional form of the first passage time density (FPTD) of a tracer particle in a single-file diffusion (SFD) system whose population is: (i) homogeneous, i.e., all particles having the same diffusion constant and (ii) heterogeneous, with diffusion constants drawn from a heavy-tailed power-law distribution. In parallel, the full FPTD for fractional Brownian motion [fBm-def
Mutations in HPV16 L1 hypervariable surface-exposed loops affect L2 binding and DNA encapsidation.
Prophylactic vaccines against human papillomavirus (HPV) based on Virus-Like Particles (VLPs) induce type-specific neutralizing antibodies against a small number of hypervariable residues positioned in surface-exposed loops of the major capsid protein L1. To investigate the importance of these residues for neutralization, cross-neutralization, L2 incorporation and genome encapsidation, ten surface
Fourier-transform inelastic X-ray scattering from time- and momentum-dependent phonon-phonon correlations
The macroscopic characteristics of a material are determined by its elementary excitations, which dictate the response of the system to external stimuli. The spectrum of excitations is related to fluctuations in the density-density correlations and is typically measured through frequency-domain neutron(1) or X-ray(2-4) scattering. Time-domain measurements of these correlations could yield a more d
Workplace bullying, sleep problems and leisure-time physical activity: a prospective cohort study
Reduced Growth of Soybean Seedlings After Exposure to Weak Microwave Radiation From GSM 900 Mobile Phone and Base Station
The aim of this work was to study possible effects of environmental radiation pollution on plants. The association between cellular telephone (short duration, higher amplitude) and base station (long duration, very low amplitude) radiation exposure and the growth rate of soybean (Glycine max) seedlings was investigated. Soybean seedlings, pre-grown for 4 days, were exposed in a gigahertz transvers
