PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and workup of detected findings have not yet been standardized. The aim of th

Acrylic Tanks for Stunning Chemical Demonstrations

We describe the use of acrylic tanks (400 x 450 x 27 mm) for visualization of chemical demonstrations in aqueous solutions. Examples of well-suited demonstrations are oscillating reactions, pH indicators, photochemical reduction of Lauth's violet, and chemoluminiscent reactions.

Supply chain integration obtained through uniquely labelled goods: A survey of Swedish manufacturing industries

Purpose – This paper aims to examine the use of unique identities (through radio frequency identification technology, bar codes and “human-readable” labels) on packages and load carriers in Swedish manufacturing industries. The purpose is to investigate drivers behind the adoption, the perceived improvements and visions for the coming 2-5 years. It also covers different methods for reading the ide

High p(T) identified particle production. in ALICE

The ALICE experiment is a dedicated heavy-ion physics detector at the LHC with unique capabilities for studying identified particle production. In this proceeding preliminary results for R-AA of pi and K+p (sum), are reported, based on measurements in pp at root s = 2.76 TeV and Pb-Pb at root s(NN) = 2.76 TeV. The results are compared to theoretical predictions and measurements at RHIC.

Visual pigment in the lens eyes of the box jellyfish Chiropsella bronzie.

Box jellyfish (Cubomedusae) possess a unique visual system comprising 24 eyes of four morphological types. Moreover, box jellyfish display several visually guided behaviours, including obstacle avoidance and light-shaft attractance. It is largely unknown what kind of visual information box jellyfish use for carrying out these behaviours. Brightness contrast is almost certainly involved, but it is

Low-dose computed tomography of the lumbar spine: a phantom study on imaging parameters and image quality

Background: Lumbar spine radiography has limited diagnostic value but low radiation dose compared with computed tomography (CT). The average effective radiation dose from lumbar spine radiography is about 1.1 mSv. Low-dose lumbar spine CT may be an alternative to increase the diagnostic value at low radiation dose, around 1 mSv. Purpose: To determine the optimal settings for low-dose lumbar spine

Sinusoidal Order Estimation using Angles between Subspaces

Abstract in UndeterminedWe consider the problem of determining the order of a parametric model from a noisy signal based on the geometry of the space. More specifically, we do this using the nontrivial angles between the candidate signal subspace model and the noise subspace. The proposed principle is closely related to the subspace orthogonality property known from the MUSIC algorithm, and we stu

Organization of Bacteriochlorophylls in Individual Chlorosomes from Chlorobaculum tepidum Studied by 2-Dimensional Polarization Fluorescence Microscopy

Chlorosomes are the largest and most efficient natural light-harvesting systems and contain supramolecular assemblies of bacteriochlorophylls that are organized without proteins. Despite a recent structure determination for chlorosomes from Chlorobaculum tepidum (Ganapathy et al. Proc. Natl. Acad. Sci. U.S.A. 2009, 106, 8525), the issue of a possible large structural disorder is still discussed co

A 2-D GRO Vernier Time-to-Digital Converter with Large Input Range and Small Latency

Abstract — The proposed time-to-digital converter (TDC) arranges two Vernier gated-ring-oscillator (GRO) branches in a 2-dimension (2-D) fashion. All delay differences between X-axis phases and Y-axis phases (based on 2-D definition) can be used, rather than only the diagonal line. The large latency time inherited from Vernier structure is therefore dramatically reduced. The TDC is implemented in

A Single Nucleotide Polymorphism Associates With the Response of Muscle ATP Synthesis to Long-Term Exercise Training in Relatives of Type 2 Diabetic Humans

OBJECTIVE-Myocellular ATP synthesis (fATP) associates with insulin sensitivity in first-degree relatives of subjects with type 2 diabetes. Short-term endurance training can modify their fATP and insulin sensitivity. This study examines the effects of moderate long-term exercise using endurance or resistance training in this cohort. RESEARCH DESIGN AND METHODS-A randomized, parallel-group trial tes

Fc{gamma}RIIB Inhibits the Development of Atherosclerosis in Low-Density Lipoprotein Receptor-Deficient Mice.

The immune processes associated with atherogenesis have received considerable attention during recent years. IgG FcRs (FcgammaR) are involved in activating the immune system and in maintaining peripheral tolerance. However, the role of the inhibitory IgG receptor FcgammaRIIB in atherosclerosis has not been defined. Bone marrow cells from FcgammaRIIB-deficient mice and C57BL/6 control mice were tra

Musikupplevelser - psykologiska synpunkter

Artikeln ger en översikt över hur man med socialpsykologiska teorier kan närma sig en beskrivning av upplevelser av musik. En tentativ slutsats är att musik är en resurs för identitetsskapande där kognitiva, emotionella och sociala faktorer är aktiva.

Platelet-dependent accumulation of leukocytes in sinusoids mediates hepatocellular damage in bile duct ligation-induced cholestasis

Background:Although it is well known that extrahepatic cholestasis induces liver damage, the mechanisms are still not completely understood. The aim of the present study was to evaluate the role of platelets and P-selectin in cholestasis-induced liver injury.Experimental approach:C57BL/6 mice underwent bile duct ligation (BDL) and pretreatment with an anti-GP1balpha antibody, which depletes platel

Psychosocial consequences of false-positive mammography among women attending breast cancer screening. Assessment, prediction, and coping.

Popular Abstract in Swedish Bröstcancer är den vanligaste dödsorsaken bland cancersjuka kvinnor. Därför rekommenderas regelbundna mammografiska hälsokontroller för tidig diagnostik och snar behandling för att förbättra prognosen. I Sverige rekommenderas kontroller för kvinnor mellan 40-74 år. Mammografiska hälsokontroller medför dock även risker, såsom till exempel behov av kompletterande bröstundOne side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsi

Locally based research and development units as knowledge brokers and change facilitators in health and social care of older people in Sweden

This article investigates the role of locally based research and development units (R&Ds) focusing on health and social services. Nearly 300 Local R&Ds are funded by the Swedish government with the intention to facilitate knowledge transfer and development of high quality and effective health and social care organisations. Based on analyses of archival data on aims, activities and outputs

Confirmed association between neonatal phototherapy or neonatal icterus and risk of childhood asthma

We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Pres

Dysphagia in Lewy body dementia - a clinical observational study of swallowing function by videofluoroscopic examination

Background: Dysphagia, which can result in aspiration pneumonia and death, is a well-known problem in patients with dementia and Parkinson's disease. There are few studies on dysphagia in patients with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), especially studies objectively documenting the type of swallowing dysfunction. The aim of this study was therefore to investig

Stakeholders' Opinions on a Future In-Vehicle Alcohol Detection System for Prevention of Drunk Driving

Introduction: There is a common understanding that driving under the influence of alcohol is associated with higher risk of being involved in crashes with injuries and possible fatalities as the outcome. Various countermeasures have therefore from time to time been taken by the authorities to prevent drunk driving. One of them has been the alcohol interlock. Up to now, interlocks have mainly been
