Background: Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigate

We have estimated affinities for the binding of 34 ligands to trypsin and nine guest molecules to three different hosts in the SAMPL3 blind challenge, using the MM/PBSA, MM/GBSA, LIE, continuum LIE, and Glide score methods. For the trypsin challenge, none of the methods were able to accurately predict the experimental results. For the MM/GB(PB)SA and LIE methods, the rankings were essentially rand

Production of synthetic vehicle fuels from biomass is a hot topic. There are several alternative fuels to consider when evaluating properties such as cost of production and energy efficiency to both product and final use in a road vehicle. Thermochemical conversion via gasification and downstream synthesis of fuels as well as biochemical conversion of woody biomass to ethanol is considered in this

A pentose-rich hydrolysate fraction obtained by extraction of steam-pretreated sugarcane bagasse was analysed with regard to dissolved phenolics. The liquid obtained after steam pretreatment (2% SO2 (w/w) at 190 ◦C for 5min)was divided into two parts: one containing dissolved compounds originating from hemicellulose (with xylose as the dominating compound), and the other containing predominantly d

A Monte-Carlo simulation package has been developed to model the response of a detector system for ion identification used in conjunction with ion separators following nuclear reactions. The simulation is written predominantly using the GEANT4 framework but utilises the ion transport code MOCADI for accurate separator and reaction modelling. A novel MOCADI-GEANT4 interface has been developed to ut

Neuronal endoplasmic reticulum (ER), continuous from soma to dendritic spines, undergoes rapid fragmentation in response to N-methyl-D-aspartate (NMDA) receptor stimulation in hippocampal slices and neuronal primary cultures. Here, we show that ER fragments in the mouse brain following cardiac arrest (CA) induced brain ischemia. The ER structure was assessed in vivo in cortical pyramidal neurons i

FLT3 and c-KIT are crucial regulators of hematopoietic stem and progenitor cells. We investigated the role of STS1 and STS2 on FLT3 and c-KIT phosphorylation, activity, and function in normal and stress-induced hematopoiesis. STS1/STS2-deficient mice show a profound expansion of multipotent progenitor and lymphoid primed multipotent progenitor cells with elevated colony-forming capacity. Although

Popular Abstract in Swedish Sedan den industriella revolutionen har världen konfronterats med många miljöproblem, t.ex. luftföroreningar, surt regn, global uppvärmning, farligt avfall, ozonhålsproblematik, ”smog” och vattenföroreningar. Det är viktigt att utveckla mätteknik för att objektivt kunna fastställa miljöförhållandena för att sedan kunna göra adekvata åtgärder. Miljön kan direkt karakteriThis thesis studies the techniques of laser remote sensing and their applications in environmental monitoring, as documented in several published papers. The environment where the human being live is degrading with an accelerating speed. Quantitative monitoring characterizes the quality of the environment and offers possibilities to solve environmental problems. Laser remote sensing actively prob

Patients and methods: Participants completed the Hospital Anxiety and Depression Scale and two subscales, Vitality and Mental Health, in the SF-36 4-8 weeks (T1) (n = 61), 6 (T2) (n = 57), 12 (T3) (n = 50), and 18 (T4) months (n = 48) after diagnosis. I-State as Object of Analysis was used to identify a finite set of states based on three dimensions. Cluster analysis was carried out using Ward's m

Objective. Post-treatment prostate biopsy side-effects were evaluated in patients with locally advanced prostate cancer on endocrine therapy alone or combined with radiotherapy in the Scandinavian Prostate Cancer Group-7 randomized trial. Material and methods. One-hundred and twenty patients underwent transrectalultrasound-guided biopsy, and were requested to complete a questionnaire on side-effec

Intractable seizures and lack of effective antiepileptic drugs (AED) are severe and common conditions affecting many patients with epilepsy. Thus, there is an urgent need to develop new therapies in epilepsy. The search for novel treatments has identified several neuropeptide systems as potential targets for future therapeutic interventions. The neuropeptide Y (NPY) may represent one such target,

Objective: The objective of this study was to examine the prevalence of selfreported experiences of potential childhood traumas and polytraumatization, and to find cut-off values for different kinds of potential traumatic events in a national representative sample of adults in Sweden. In addition, to analyse the association between polytraumatization and both psychological distress and global self

In the year 1900, Sweden probably had the oldest population in the contemporary world. It was also the first nation to implement a universal pension system in 1913. The universal character in early social legislation has certainly been decisive for the development of the Swedish welfare state. This alternative has not been self-evident. Why did the reforms turn universal, when the continental mode

Purpose: Recently, there has been an increasing interest in operating conventional linear accelerators without a flattening filter. The aim of this study was to determine beam quality variations as a function of off-axis ray angle for unflattened beams. In addition, a comparison was made with the off-axis energy variation in flattened beams. Methods: Two Elekta Precise linear accelerators were mod
