The Global Prevalence of Infections in Urology (GPUI) Study : A Worldwide Surveillance Study in Urology Patients

The GPIU study is currently the only study registering health care–associated urogenital tract infections, especially in urology patients, in an ongoing surveillance protocol that can help to deliver data on adequate empirical antibiotic therapy in hospitalised urology patients according to guideline recommendations. The annual GPIU study will continue to be performed in November of each year unde

Endocrine and metabolic diurnal rhythms in young adult men born small vs appropriate for gestational age

OBJECTIVE: Sleep disturbances and alterations of diurnal endocrine rhythms are associated with increased risk of type 2 diabetes (T2D). We previously showed that young men born small for gestational age (SGA) and with increased risk of T2D have elevated fat and decreased glucose oxidation rates during nighttime. In this study, we investigated whether SGA men have an altered diurnal profile of horm

A new plastic scintillation resin for single-step separation, concentration and measurement of technetium-99

Technetium is a synthetic element with no stable isotopes, produced as waste in nuclear power plants and in cyclotrons used for nuclear medicine. The element has high mobility, in the form of TcO4 −; its determination is therefore important for environmental protection. Technetium is found in low concentrations and therefore common methods for its analysis include long treatments in several steps

Neurite density imaging versus imaging of microscopic anisotropy in diffusion MRI : A model comparison using spherical tensor encoding

In diffusion MRI (dMRI), microscopic diffusion anisotropy can be obscured by orientation dispersion. Separation of these properties is of high importance, since it could allow dMRI to non-invasively probe elongated structures such as neurites (axons and dendrites). However, conventional dMRI, based on single diffusion encoding (SDE), entangles microscopic anisotropy and orientation dispersion with

Den offentliga ekonomen : En svårbestämd multikonstnär

Under de senaste tjugo åren har offentlig sektor blivit alltmer präglad av New Public Management (NPM). Såväl beskrivningar som konkretiseringar av NPM varierar men två drag återkommer som gemensam nämnare; dels att offentlig sektor har närmat sig den privata i sättet att styra och organisera verksamheten, dels att betoningen har skiftat från ansvar för processer till ansvar för resultat.Med resul

Predicting bee community responses to land-use changes : Effects of geographic and taxonomic biases

Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, and mitigate bees' responses to these human impacts. The available data are, however, geographically and taxonomically unrepresentative; most data are from North America and Western Europe, overrepresenting bumblebees and raising concer

The Smallest Eigenvalue of the Generalized Laplacian Matrix, with Application to Network-Decentralized Estimation for Homogeneous Systems

The problem of synthesizing network-decentralized observers arises when several agents, corresponding to the nodes of a network, exchange information about local measurements to asymptotically estimate their own state. The network topology is unknown to the nodes, which can rely on information about their neighboring nodes only. For homogeneous systems, composed of identical agents, we show that a

Broken Data : Broken World

In a world where predictive big data analytics and data driven policy and design are increasingly prevalent, the concept of broken data seeks to interrogate and disrupt the possibilities associated with these trends. Concepts of breakage, damage and repair, and recent literatures about ‘broken world’ type theories, offer us an alternative starting point: what are the implications of putting these

Multistable Fields

September 19th 2015 the exhibition/installation Multistable Fields opened in the atrium of the main building at Lund university. Here’s the synopsis:The main building of Lund University was inaugurated in 1882. In the building conceived by architect Helgo Zettervall the rational quest for knowledge of Academia is enmeshed with a world of mythical symbols. Sphinxes and griffins meet deans and profe

The north-eastern aeolian 'European Sand Belt' as potential record of environmental changes : A case study from Eastern Latvia and Southern Estonia

The Latvian and Estonian inland dunes belong to the north-eastern part of the 'European Sand Belt' (ESB). These dunes are widely distributed over broad glaciolacustrine plains and Late Glacial alluvial deltas, considered to be potential sources for the aeolian material. Little is known about these aeolian sediments and their substratum; here we present a detailed sedimentary structural and textura

CP40 from Corynebacterium pseudotuberculosis is an endo-β-N-acetylglucosaminidase

Background: C. pseudotuberculosis is an important animal pathogen that causes substantial economical loss in sheep and goat farming. Zoonotic infections in humans are rare, but when they occur they are often severe and difficult to treat. One of the most studied proteins from this bacterium, the secreted protein CP40 is being developed as a promising vaccine candidate and has been characterized as

Photochemistry of Carboxylate on TiO2(110) Studied with Synchrotron Radiation Photoelectron Spectroscopy

We present a dedicated synchrotron radiation photoelectron spectroscopy (SR-PES) study of a photochemical reaction on the surface of rutile TiO2(110). The photoreaction kinetics of carboxylate species (trimethyl acetate, TMA) upon irradiation by UV and soft X-rays were monitored, and we show that it is possible to control the reaction rates from UV light and soft X-rays independently. We directly

The Aggregation Paths and Products of Aβ42 Dimers Are Distinct from Those of the Aβ42 Monomer

Extracts of Alzheimer's disease (AD) brain that contain what appear to be sodium dodecyl sulfate-stable amyloid β-protein (Aβ) dimers potently block LTP and impair memory consolidation. Brain-derived dimers can be physically separated the Aβ monomer, consist primarily of Aβ42, and resist denaturation by chaotropic agents. In nature, covalently cross-linked Aβ dimers could be generated in two ways:

An international study of hospitalized cancer patients’ health status, nursing care quality, perceived individuality in care and trust in nurses : A path analysis

Background Providing high quality nursing care for patients with malignancies is complex and driven by many factors. Many of the associations between nursing care quality, trust, health status and individualized care remain obscure. Objective To empirically test a model of association linking hospitalized cancer patients’ health status, nursing care quality, perceived individuality in care and tru
