Target-specific molecular imaging with radiolabeled antibodies has experienced a rapid growth over the past 20 years, and is now an essential tool to provide information on disease presence and extent. Despite all efforts to detect and control prostate cancer at an early stage, a number of men are still progressing to develop incurable metastatic disease. Because of this, development of new method
Aerodynamic four-way coupling models are necessary to handle two-phase flows with a dispersed phase in regimes in which the particles are neither dilute enough to neglect particle interaction nor dense enough to bring the mixture to equilibrium. We include an aerodynamic particle interaction model within the framework of large eddy simulation together with Lagrangian particle tracking. The particl
We report on the particle assisted synthesis of core-shell AlP-GaP nanowires by use of metal-organic vapor phase epitaxy. The core-shell approach is chosen such as to stabilize the AlP which is highly sensitive to water. The nanowires were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. These nanowires have an indirect band
This article explores the proposition that a reason for high agricultural productivity in the early nineteenth century was relatively high energy availability from draught animals. The article is based on the collection of extensive new data indicating different trends in draught power availability and the efficiency of its use in different countries of Europe. This article shows that the proposit
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
Balance disorders are common in elderly people, not only resulting in distressing sensations but also leading to reduced activity levels and quality of life. It has been estimated that 30% of elderly patients experience a balance disorder. Managing these disorders is a substantial challenge for patients and their caregivers and physicians. Moreover, abnormalities in balance are associated with fal
Background: A delay in surgical nerve repair results in impaired nerve function in humans, but mechanisms behind the weakened nerve regeneration are not known. Activating transcription factor 3 (ATF3) increases the intrinsic growth state of injured neurons early after injury, but the role of long-term changes and their relation to axonal outgrowth after a delayed nerve repair are not well understo
Reklamen blinkar, ljuder, ändrar färg och form. Söta djur och maskotar svischar förbi, tonas ned, dyker plötsligt upp igen. Köp, beställ, registrera dig, klicka här! Ibland skriker den högljutt. Ibland är den helt tyst, knappt synlig, svår att fånga, svår att skilja ut, men uppmuntrar till interaktion och pockar på barns uppmärksamhet.

The most typical enhancement for electrokinetic remediation (EKR) involves the neutralization of the alkaline front generated at the cathode by the addition of an acid to the catholyte. Although the use of strong and weak acids can be found in the literature, there is still a clear lack of reliable comparisons between them. This paper presents a comparison of the results obtained for a real lead c
The objective of this exploratory study was to develop signal processing methods for assisting in the diagnosis of arteriovenous fistula stenosis on patients suffering from end-stage renal disease and undergoing haemodialysis treatments. The proposed method is based on the classification of vessels sounds utilizing parameter extraction from wavelets transform coefficients. The coefficients energy
Popular Abstract in Swedish Joniserande strålning används ofta som behandling vid olika tumörsjukdomar i bukhåla och bäckenregion men är ibland förenad med biverkningar. Dessa kan uppkomma tidigt/akut, dvs i direkt anslutning till genomförd behandling eller sent, efter månaderår. Besvären kan vara av mycket varierande och ofta lindrig övergående karaktär såsom buksmärtor, diarré och blödningar fråGastrointestinal tract damage is an insidious feature in patients undergoing radiotherapy. Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enteropathy. The aim of this thesis was to investigate the basic mechanisms behind leukocyte-platelet-end
The glial cell line-derived neurotrophic factor (GDNF) has an important role in neuronal survival through binding to the GFRα1 (GDNF family receptor alpha-1) receptor and activation of the receptor tyrosine kinase Ret. Transient brain ischemia alters the expression of the GDNF signaling machinery but whether the GDNF receptor proteins are also affected, and the functional consequences, have not be
Popular Abstract in Swedish Made in China - På hur många av dina barns leksaker står det? Produktionen inom många sektorer flyttas från Europa till länder där arbetskraften är billigare. Forskningen i avhandlingen "Modeling and Control of Stiff Robots for Flexible Manufacturing" ska hjälpa europeiska småföretag att bli mer konkurrenskraftiga och samtidigt underlätta för arbetarna. Högt ljud frånTo survive on a global market, small and medium size enterprises (SMEs) require affordable and competitive industrial automation for high quality flexible manufacturing. This thesis contributes to the development of robot concepts that fit the needs of SMEs. A major part of the thesis deals with the modeling of the three degree-of-freedom (DOF) Gantry-Tau parallel kinematic robot, which has the po
Background: Despite conflicting results after surgically treated ankle fractures few studies have evaluated the effects of different types of training programs performed after plaster removal. The aim of this study was to evaluate the effects of a 12-week standardised but individually suited training program ( training group) versus usual care ( control group) after plaster removal in adults with
This study aimed to assess the costs and benefits of three alternative second-line treatment strategies for Swedish patients with type 2 diabetes mellitus (T2DM) who fail to reach glycated hemoglobin (HbA1c) ≤ 7% with metformin treatment alone: glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors, and neutral protamine Hagedorn (NPH) insulin.
The aim of this myocardial perfusion imaging (MPI) study was to compare the diagnostic performance of two computer-aided diagnosis (CAD) systems, EXINI Heart(TM) (EXINI), and PERFEXTM (PERFEX) Emory Cardiac Toolbox (ECT), and the summed stress score (SSS) values from both software packages. We studied 1,052 consecutive patients who underwent 2-day stress/rest Tc-99m-sestamibi MPI studies. The refe
There is growing evidence of the importance of extramatrical mycelium (EMM) of mycorrhizal fungi in carbon (C) cycling in ecosystems. However, our understanding has until recently been mainly based on laboratory experiments, and knowledge of such basic parameters as variations in mycelial production, standing biomass and turnover as well as the regulatory mechanisms behind such variations in fores
