The complete 1H NMR assignments have been obtained for five mutant proteins of calbindin D9k and the three-dimensional solution structures determined for two of the mutants. The structures have been determined using distance geometry and simulated annealing, with distance constraints from NMR. All mutants have modifications in the first calcium-binding site of calbindin (the N-terminal site design

A simplified description and a corresponding force field for polypeptides is introduced. Each amino acid residue is reduced to one interaction site, representing the backbone, and one or two side chain sites depending on its size and complexity. Site–site interactions are parameterized after a hydrophobicity criterium. The treatment of backbone sites is in addition designed to reproduce typical po

Background: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for

Background: Western multicenter studies on distal pancreatectomy with celiac axis resection (DP-CAR), also known as the Appleby procedure, for locally advanced pancreatic cancer are lacking. We aimed to study overall survival, morbidity, mortality and the impact of preoperative hepatic artery embolization (PHAE). Methods: Retrospective cohort study within the European-African Hepato-Pancreato-Bili

Monte Carlo simulations of linear polyelectrolytes together with explicit ions have been performed in a spherical cell model to study conformational changes and activity coefficients in relation to the isoionic dilution method used in viscosity measurements. The results show that it is possible to define an effective ionic strength that will keep the average chain conformation constant on isoionic

The isoionic dilution method was used to measure the intrinsic viscosity, [η], and the Huggins coefficient, K(H), of two poly(acrylic acid) samples, 50% neutralized with NaOH, with molecular weights 5.0 x 103 (Na50PA5) and 4.8 x 104 (Na50PA48) at different ionic strengths. For Na50PA5 at low ionic strength, [η] is higher than the value predicted by a rigid-rod model. Assuming that the chain has re

Trait-associated loci often map to genomic regions encoding long noncoding RNAs (lncRNAs), but the role of these lncRNAs in disease etiology is largely unexplored. We show that a pair of sense/antisense lncRNA (6p22lncRNAs) encoded by CASC15 and NBAT1 located at the neuroblastoma (NB) risk-associated 6p22.3 locus are tumor suppressors and show reduced expression in high-risk NBs. Loss of functiona

OBJECTIVE: To use microarray analyses of gene expression to characterize the synovial molecular pathways regulated by the arthritis regulatory locus Cia25 and to determine how it operates to control disease severity and joint damage.METHODS: Synovial tissues from DA rats and DA.ACI(Cia25) rats obtained 21 days after induction of pristane-induced arthritis were used for RNA extraction and hybridiza

According to the resource-based view, knowledge concealing is fundamental for firms’ ability to prevent competitor imitation and profit from innovation. Open innovation scholars have recently challenged this idea, proposing instead that knowledge revealing can foster industry-wide collaboration and enhance the value of innovation. Reconciling these two perspectives requires a more detailed underst

Background/Aim: Streptococci cause approximately 10% of prosthetic joint infections (PJIs). The aim of this study was to identify the characteristics of patients with streptococcal PJIs and to describe the treatment and outcome of streptococcal PJIs in Skåne county between 2011 and 2015. Methods: Patients with streptococcal PJIs with positive cultures or PCRs on samples from joint aspirate and/or

Background: Both the number and the proportion of elderly people in the society increase. The number of elderly subjects with a disability due to a disease has decreased resulting in more active elderly. Therefore, an increase in numbers of injury in the elderly population can be expected; a hypothesis that was investigated in the present study. Methods: Two-hundred sixteen patients with an age of

There is a well-documented large positive correlation between education and health and yet it remains unclear as to whether this is a causal relationship. Potential reasons for this lack of clarity include estimation using different methods, analysis of different populations and school reforms that are different in design. In this paper we assess whether the type of school reform, the instrument a

A modern catheter laboratory for the treatment of children with CHD should be in close proximity to the paediatric ICU, operating theatres, and imaging facilities. Space requirements and equipment for an up-to-date catheter laboratory are discussed. The document was endorsed by the council of the Association of European Paediatric and Congenital Cardiologists.

Background: Intermittent claudication (IC) is commonly caused by lesions in the superficial femoral artery (SFA), yet invasive treatment is still controversial and longer term patient-reported outcomes are lacking. This prospective randomized trial assessed the 24-month impact of primary stenting with nitinol self-expanding stents compared to best medical treatment (BMT) alone in patients with sta

The use of interactive visualization techniques in Digital Humanities research can be a useful addition when traditional automated machine learning techniques face difficulties, as is often the case with the exploration of large volumes of dynamic—and in many cases, noisy and conflicting—textual data from social media. Recently, the field of stance analysis has been moving from a predominantly bin

Tio skandinaviska forskare med livslång erfarenhet av studier och forskning om Indien har skrivit originalartiklar kring sina specialområden såsom ekonomi, politik, kvinnofrågor, sociala förhållanden, kultur och religion. Boken söker sig under ytan av gängse Indienbilder och försöker förstå det moderna Indien i ett historiskt perspektiv som en del av en dynamik där också framtiden avtecknar sig.

Indiens historia ur ett samhällsvetenskapligt perspektiv

Landsbygdens förändring under de senaste femtio åren. Grön revolution och mekanisering av jordbruket. Arbetsmigration till städerna. Kasternas frigörelse. Regional politik.

Miljön hotas av förgiftning av luft, vatten och jordar. Industriutveckling och gruvdrift förstör miljön, liksom användningen av kol och bensin i de ständigt ökande transporter. Indiens möjligheter att komma till rätta med detta.
