Measurements of Higgs boson production and couplings in the four-lepton channel in pp collisions at center-of-mass energies of 7 and 8 TeV with the ATLAS detector

The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H -> ZZ* -> l(+)l(-)l(+)l'(-), where l, l' = e or mu, are presented. These measurements were performed using pp collision data corresponding to integrated luminosities of 4.5 and 20.3 fb(-1) at center-of-mass energies of 7 and 8 TeV, respectively, recorded with the ATLAS detector at the LHC. The H -> ZZ

Development and validation of the Fast Assessment in Acute Treatment of Psychosis-Observation Rating Scale (FAST-O)

Objectives. There is a need for an observation scale for assessment and monitoring of acutely psychotic patients. Milestones based on such ratings should be defined, similar to the PANSS-based Remission criteria. FAST-O is such an instrument (11 items and a CGI rating). Methods. Reliability, validity and factor structure were analyzed in four separate studies-most importantly in one study of 33 ch

Alzheimer's disease (AD) and executive dysfunction. A case-control study on the significance of frontal white matter changes detected by diffusion tensor imaging (DTI).

White matter (WM) changes are frequently seen on structural imaging in AD but the clinical relevance of these changes is uncertain. Frontal WM pathology is often observed upon neuropathological examination in AD. Since frontal cortical/sub-cortical pathology is known to relate to executive dysfunction, the aim was to elucidate if frontal WM changes in AD correlated with executive dysfunction. In a

Human oral, gut, and plaque microbiota in patients with atherosclerosis

Periodontal disease has been associated with atherosclerosis, suggesting that bacteria from the oral cavity may contribute to the development of atherosclerosis and cardiovascular disease. Furthermore, the gut microbiota may affect obesity, which is associated with atherosclerosis. Using qPCR, we show that bacterial DNA was present in the atherosclerotic plaque and that the amount of DNA correlate

A fast 2D tissue motion estimator based on the phase of the intensity enables visualization of the propagation of the longitudinal movement in the carotid artery wall

A fast 2D motion estimator has been developed and evaluated. The method does not utilize block-matching or iterative solutions and is thus more computationally efficient and suitable for real-time motion estimation over the entire image. The method has been evaluated on 1) phantom measurements and 2) in vivo on the carotid artery wall of 17 subjects, where measurements of the longitudinal displace

Evaluation of the Cover Effect in Mafraq Landfill –Jordan Using Hydrus-2d Simulation

In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var

This thesis is a contribution to the understanding of the life and work of Arnold Schoenberg as well as to musical hermeneutics. The aims are (1) to scrutinize Arnold Schoenberg’s marital crisis of the year 1908, (2) to probe into the meanings of some representative musical works during this very period, and (3) to compare features in Schoenberg’s life and his creative work. A number of documents

Down-regulation of human extracellular cysteine protease inhibitors by the secreted staphylococcal cysteine proteases, staphopain A and B.

Of seven human cystatins investigated, none inhibited the cysteine proteases staphopain A and B secreted by the human pathogen Staphylococcus aureus. Rather, the extracellular cystatins C, D and E/M were hydrolyzed by both staphopains. Based on MALDI-TOF time-course experiments, staphopain A cleavage of cystatin C and D should be physiologically relevant and occur upon S. aureus infection. Staphop

Holocene recolonization and extinction of the pond turtle, Emys orbicularis (L., 1758), in Europe

We reconstruct the Holocene range fluctuations of the European pond turtle (Emys orbicularis) for northern and Central Europe. Based on 529 subfossil records and radiocarbon dating of critical finds, we provide evidence that E. orbicularis experienced a rapid range expansion with Holocene warming. Phylogeographic data argue for a colonization of northern and Central Europe from a glacial refuge lo

Electronic speckle pattern interferometry: A novel non-invasive tool for studying drug transport rate through free films

In this work, Electronic Speckle Pattern Interferometry (ESPI) is presented as a non-invasive tool to study drug transport in controlled release systems. ESPI is shown to be a feasible tool to measure drug film permeability via comparison with an ordinary diaphragm cell. A specially designed cuvette was used in the release study: the polymeric film separated the donor and the receiving chambers of

Platelets synthesize large amounts of active plasminogen activator inhibitor 1

Previous studies have suggested that plasminogen activator inhibitor 1 (PAI-1) released from platelets convey resistance of platelet-rich blood clots to thrombolysis. However, the majority of PAI-1 in platelets is inactive and therefore its role in clot stabilization is unclear. Because platelets retain mRNA and capacity for synthesis of some proteins, we investigated if platelets can de novo synt

Can selective serotonin inhibitor drugs in elderly patients in nursing homes be reduced?

OBJECTIVE: To investigate whether treatment with selective serotonin reuptake inhibitors (SSRIs) could be withdrawn for elderly residents who had been on treatment for at least one year and to evaluate a method for systematic drug review. DESIGN: Open, prospective, interventional study. SETTING: Four counties in Sweden. SUBJECTS: Elderly residents at 19 nursing homes, with ongoing treatment with S

Real-time control of a virtual hand

A myoelectric control system for prostheses was developed and evaluated on six healthy subjects. These were able to control a computer-animated hand in real-time with a 20 Hz update rate. A data glove, equipped with joint angle sensors, was used to train the system and to evaluate the continuous predictions of joint angles. A linear envelop filter was used for EMG signal pre-processing and the rec

The influence of extensive vegetated roofs on runoff water quality

The influence of extensive sedum-moss vegetated roofs on runoff water quality was studied for four full scale installations located in southern Sweden. The aim of the study was to ascertain whether the vegetated roof behaves as a sink or a source of pollutants and whether the age of a vegetated roof influences runoff quality. The runoff quality from vegetated roofs was also compared with the runof

Cobalt-containing alloys and their ability to release cobalt and cause dermatitis

Cobalt, nickel, and chromium are important skin sensitizers. However, knowledge about cobalt exposure and causes of cobalt sensitization is limited. To study release of cobalt, nickel, and chromium from some cobalt-containing hard metal alloys and to test reactivity to the materials in cobalt-sensitized patients. Discs suitable for patch testing were made of some hard metal alloys. Cobalt, nickel,

The amino-terminal part of PRELP binds to heparin and heparan sulfate

PRELP (proline, arginine-rich end leucine-rich repeat protein) is an extracellular matrix leucine-rich repeat protein. The amino-terminal region of PRELP differs from that of other leucine-rich repeat proteins in containing a high number of proline and arginine residues. The clustered proline and basic residues are conserved in rat, bovine, and human PRELP. Although the function of PRELP is not ye

Accessibility to the public environment as perceived by teenagers with functional limitations in a south Swedish town centre.

PURPOSE: Owing to physical inaccessibility persons with mobility restrictions and other functional limitations often face problems in public environments, leading to restrictions in activity and participation. To investigate general accessibility and perceived problems of accessibility to the public environment in a town centre, as well as visiting preferences to public facilities, among teenagers

Distribution patterns of transforaminal injections in the cervical spine evaluated by multi-slice computed tomography.

Transforaminal injections are sometimes used for the diagnosis and treatment of painful conditions in the lumbar and to a lesser degree in the cervical spine. The technique is most often used when investigating/treating radiculopathy caused by degenerative disease. But how selective are the nerve root blocks? What possible structures other than the intended nerve root are affected from such inject

Intracellular co-localization of trypsin-2 and matrix metalloprotease-9: Possible proteolytic cascade of trypsin-2, MMP-9 and enterokinase in carcinoma

Tumor-associated trypsin-2 and matrix metalloprotease-9 (MMP-9) are associated with cancer, particularly with invasive squamous cell carcinomas. They require activation for catalytical competence via proteolytic cascades. One cascade is formed by enterokinase, trypsin-2 and MMP-9; enterokinase activates trypsinogen-2 to trypsin-2, which is an efficient proMMP-9 activator. We describe here that ora
