Isolated hepatic perfusion as a treatment for uveal melanoma liver metastases (the SCANDIUM trial): study protocol for a randomized controlled trial

Background: Uveal melanoma is the most common primary intraocular malignancy in adults. Despite successful control of the primary tumor, metastatic disease will ultimately develop in approximately 50% of patients, with the liver being the most common site for metastases. The median survival for patients with liver metastases is between 6 and 12 months, and no treatment has in randomized trials eve

DNA with amphiphilic counterions: tuning colloidal DNA with cyclodextrin

DNA compaction in vitro can be controlled by lipids. Cyclodextrins can disperse lipids in the form of water soluble inclusion complexes, thus tuning their self-assembly. To progress in the fundamental understanding of double-stranded (ds) DNA-lipid-cyclodextrin interactions, the aqueous phase behavior of a cationic surfactant (dodecyltrimethylammonium, DTA)-dsDNA compound in the presence of cyclod

Good or bad bioethanol from a greenhouse gas perspective - What determines this?

The purpose of this study is to describe how the greenhouse gas (GHG) benefits of ethanol from agricultural crops depend on local conditions and calculation methods. The focus is mainly on the fuels used in the ethanol process and biogenic GHG from the soils cultivated. To ensure that "good" ethanol is produced, with reference to GHG benefits, the following demands must be met: (i) ethanol plants

Hermitian Young operators

Starting from conventional Young operators, we construct Hermitian operators which project orthogonally onto irreducible representations of the (special) unitary group. (C) 2014 AIP Publishing LLC.

Employee Self-rated Productivity and Objective Organizational Production Levels Effects of Worksite Health Interventions Involving Reduced Work Hours and Physical Exercise

Objective: To investigate how worksite health interventions involving a 2.5-hour reduction of weekly working hours with (PE) or without (RWH) mandatory physical exercise affects productivity. Methods: Six workplaces in dental health care were matched and randomized to three conditions (PE, RWH and referents). Employees' (N = 177) self-rated productivity and the workplaces' production levels (numbe

Immunosuppressive Myeloid Cells in Breast Cancer and Sepsis

Popular Abstract in Swedish Normalt sett skyddar immunförsvaret oss mot farliga och främmande ämnen. En cancercell uppfattas oftast som något defekt och farligt som måste elimineras. Men då och då lyckas cancerceller överleva och manipulerar då vårt immunförsvar till det sämre för oss. Cancer är ett samlingsnamn på sjukdomar orsakade av en ansamling av genetiska förändringar. Dessa förändringar Immune cells play paradoxical roles in cancer progression. On one hand, the immune system protects us against tumor development by recognizing and eliminating cancerous cells. On the other hand, tumor-associated immune cells can contribute to tumor progression by secreting growth factors as well as immunosuppressive, pro-angiogenic and/or pro-metastatic mediators. In this thesis we identified a f

How much variation in the molt duration of passerines can be explained by the growth rate of tail feathers?

In birds, molt duration is an important trait that can affect plumage functionality and, consequently, the fitness of individuals. However, knowledge about the factors that affect variation in molt speed is sparse, mostly because of the methodological difficulties of studying avian molt. We used a ptilochronology-based approach to estimate the rate at which tail feathers were produced during molt

Northern magnetic displacements trigger endogenous fuelling responses in a naive bird migrant

In a previous study, we found that juvenile northern wheatears (Oenanthe oenanthe) exposed to a magnetic displacement to the west of their natural migration route increased their body mass. The total intensity and inclination used for the western displacement may also have been interpreted as northern compared to the experimental site (stronger total field intensity and steeper inclination angle).

Non-invasive diagnostic methods of intracranial arteries

Aims of this thesis were to compare the agreement of different magnetic resonance angiography(MRA) techniques and digital subtraction angiography (DSA) in follow-up of intracranial aneurysms treated with coils in order to select the best MRA method, to evaluate the impact of increased iodine concentration in contrast medium and decreased tube voltage on arterial attenuation and image quality in co

Holocene geocentric dipole tilt model constrained by sedimentary paleomagnetic data

Paleomagnetic data, although undeniably limited, have been used to constrain complex time-varying geomagnetic field models. Here we present four different versions of a time varying geocentric dipole model for the past approximately 9000 years based on a limited selection of sedimentary paleomagnetic data with good spatial coverage. The robustness of the modeling approach is evaluated using modern

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at root s=7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb(-1). The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b

A Novel Bacterial Resistance Mechanism against Human Group IIA-Secreted Phospholipase A2: Role of Streptococcus pyogenes Sortase A.

Human group IIA-secreted phospholipase A(2) (sPLA(2)-IIA) is a bactericidal molecule important for the innate immune defense against Gram-positive bacteria. In this study, we analyzed its role in the host defense against Streptococcus pyogenes, a major human pathogen, and demonstrated that this bacterium has evolved a previously unidentified mechanism to resist killing by sPLA(2)-IIA. Analysis of

Predicted warming and browning affect timing and magnitude of plankton phenological events in lakes: a mesocosm study

1. Aquatic ecosystems in Northern Europe are expected to face increases in temperature and water colour (TB) in future. While effects of these factors have been studied separately, it is unknown whether and how a combination of them might affect phenological events and trophic interactions. 2. In a mesocosm study, we combined both factors to create conditions expected to arise during the coming ce

Large-scale association analysis provides insights into the genetic architecture and pathophysiology of type 2 diabetes

To extend understanding of the genetic architecture and molecular basis of type 2 diabetes (T2D), we conducted a meta-analysis of genetic variants on the Metabochip, including 34,840 cases and 114,981 controls, overwhelmingly of European descent. We identified ten previously unreported T2D susceptibility loci, including two showing sex-differentiated association. Genomewide analyses of these data

Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. Today there are several solutions to meet the demand for better fuel economy and one of them is the

Isomeric Ratios in 206Hg

Hg-206 was populated in the fragmentation of an E/A = 1 GeV Pb-208 beam at GSI. It was part of a campaign to study nuclei around Pb-208 via relativistic Coulomb excitation. The observation of the known isomeric states confirmed the identification of the fragmentation products. The isomeric decays were also used to prove that the correlations between beam identification detectors and the AGATA gamm
