Colloidal particles composed of amphiphilic molecules binding gadolinium complexes and peptides as tumor-specific contrast agents in MRI: physico-chemical characterization

This article highlights our recent achievements on the development and upgrade of new potential tumor-specific contrast agents for magnetic resonance imaging (MRI) based on gadolinium complexes and peptides, assemblied in amphiphilic supramolecular aggregates. The physico-chemical characterization of these aggregates provides novel and interesting opportunities to investigate surfactant aggregatio

The God Question

The essay focuses on the apophatic tradition, Western metaphysics, and the unknown God. It presents Jaspers' thoughts on transcendence as an eye-opener. To take the issue of the unknown God, two philosophers are highlighted, David Hume and Simone Weil. For Hume the concept of the unknown God presents the problem of how might anything that is unknown have any moral influence on human beings? Simone

Real-Time Camera Tracking and 3D Reconstruction Using Signed Distance Functions

The ability to quickly acquire 3D models is an essential capability needed in many disciplines including robotics, computer vision, geodesy, and architecture. In this paper we present a novel method for real-time camera tracking and 3D reconstruction of static indoor environments using an RGB-D sensor. We show that by representing the geometry with a signed distance function (SDF), the camera pose

Model Order Reduction Based on Semidefinite Programming

The main topic of this PhD thesis is complexity reduction of linear time-invariant models. The complexity in such systems is measured by the number of differential equations forming the dynamical system. This number is called the order of the system. Order reduction is typically used as a tool to model complex systems, the simulation of which takes considerable time and/or has overwhelming memory

Review of particle physics

This biennial Review summarizes much of particle physics. Using data from previous editions., plus 2778 new measurements from 645 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summarize searches for hypothetical particles such as Higgs bosons, heavy neutrinos, and supersymmetric particles. All the particle properties and s

Infants with colic - Parents’ experiences in short and long perspectives and the effect of acupuncture treatment on crying, feeding, stooling and sleep

Popular Abstract in Swedish Spädbarn med kolik – föräldrars upplevelse i ett kortare och ett längre perspektiv samt effekten av akupunktur på barnets skrik, ätande, avföringsmönster och sömn. Spädbarnskolik definieras som ett tillstånd där ett för övrigt friskt barn skriker och gnäller mer än tre timmar per dag mer än tre dagar i veckan. Kolik drabbar ca 10 % av nyfödda barn i västvärlden. Både bInfantile colic, involving an otherwise healthy infant crying and fussing more than three hours per day and more than three days per week, is a common problem in Western countries. Both the infant and the parents suffer during the months of persistent crying and there is a risk that the establishing of the early relationship might be disturbed. Safe and effective treatment that provides relief in

Improved Time-Frequency Analysis of Atrial Fibrillation Signals Using Spectral Modeling

In patients with atrial fibrillation (AF), the fibrillatory frequency trend and the time-dependent spectral characteristics can be investigated using a spectral profile technique. The spectral profile is updated by fitting each short-time spectrum. The aim of this study is to develop model-based means for stricter control on the update of the spectral profile. A spectral model defined by a superpo

Social Ecography : International trade, network analysis, and an Emmanuelian conceptualization of ecological unequal exchange

This thesis demonstrates how network analysis, ecological economics and the world-system perspective can be combined into an ecographic framework that can yield new insights into the underlying structure of the world-economy as well as its surrounding world-ecology. In particular, the thesis focuses on the structural theory of ecological unequal exchange, a theory suggesting a relationship between

Cyclin D1 expression is associated with poor prognostic features in estrogen receptor positive breast cancer

Cyclins D1 and E play an important role in breast carcinogenesis. High cyclin E expression is common in hormone receptor negative and high grade aggressive breast cancer, whereas cyclin D1 in hormone receptor positive and low grade breast cancer. Experimental data has suggested that cyclin D1 and E mediate cell proliferation by different mechanisms in estrogen receptor (ER) positive and negative b

Motor properties from persistence: a linear molecular walker lacking spatial and temporal asymmetry

The stepping direction of linear molecular motors is usually defined by a spatial asymmetry of the motor, its track, or both. Here we present a model for a molecular walker that undergoes biased directional motion along a symmetric track in the presence of a temporally symmetric chemical cycle. Instead of using asymmetry, directionality is achieved by persistence. At small load force the walker ca

Selective optical doping to predict the performance and reveal the origin of photocurrent peaks in quantum dots-in-a-well infrared photodetectors

Resonant optical pumping across the band gap was used as artificial doping in InAs/In0.15Ga0.85As/GaAs quantum dots-in-a-well infrared photodetectors. Through efficient filling of the quantum dot energy levels by simultaneous optical pumping into the ground states and the excited states of the quantum dots, the response was increased by a factor of 10. Low temperature photocurrent peaks observed a

Platinum Interference with siRNA Non-seed Regions Fine-Tunes Silencing Capacity.

Knowledge concerning the molecular mechanisms governing the influence of non-coding RNAs on protein production has emerged rapidly during the past decade. Today, two main research areas can be identified, one oriented toward the use of artificially introduced siRNAs for manipulation of gene expression, and the other one focused on the function of endogenous miRNAs. In both cases, the active molecu

Targeting Free Prostate-Specific Antigen for In Vivo Imaging of Prostate Cancer Using a Monoclonal Antibody Specific for Unique Epitopes Accessible on Free Prostate-Specific Antigen Alone.

This study investigated the feasibility of targeting the free, unbound forms of prostate-specific antigen (fPSA) for in vivo imaging of prostate adenocarcinomas (PCa), as PSA is produced and secreted at abundance during every clinical stage and grade of PCa, including castration-resistant disease. We injected (125)I-labeled monoclonal antibody PSA30 (specific for an epitope uniquely accessible on

Absence of Schroeder's Paradox in a Nanostructured Block Copolymer Electrolyte Membrane

This is a study of morphology, water uptake, and proton conductivity of a sulfonated polystyrene-block-polyethylene (PSS-PE) copolymer equilibrated in humid air with controlled relative humidity (RH), and in liquid water. Extrapolation of the domain size, water uptake, and conductivity obtained in humid air to RH = 100% allowed for an accurate comparison between the properties of PSS-PE hydrated i

Vision ergonomics at recycling centres.

All municipalities in Sweden offer their inhabitants a service for disposing of large-size and hazardous waste at local recycling centres. Opening hours at these centres include hours of darkness. The aims of this study were to 1) describe user and employee experiences of lighting and signs at Swedish recycling centres, 2) measure and assess the lighting system at the two recently built recycling

Enhanced active metabolite generation and platelet inhibitionwith prasugrel compared to clopidogrel regardless of genotype in thienopyridine metabolic pathways.

Clopidogrel response varies according to the presence of genetic polymorphisms. The CYP2C19*2 allele has been associated with impaired response; conflicting results have been reported for CYP2C19*17, ABCB1, and PON1 genotypes. We assessed the impact of CYP2C19, PON1, and ABCB1 polymorphisms on clopidogrel and prasugrel pharmacodynamic (PD) and pharmacokinetic (PK) parameters. Aspirin-treated patie

Irreducible Wavelet Representations and Ergodic Automorphisms on Solenoids

We focus on the irreducibility of wavelet representations. We present some connections between the following notions: covariant wavelet representations, ergodic shifts on solenoids, fixed points of transfer (Ruelle) operators and solutions of refinement equations. We investigate the irreducibility of the wavelet representations, in particular the representation associated to the Cantor set, introd
