Background: Although cerebrospinal fluid (CSF) biomarkers and medial temporal lobe atrophy (MTA) contribute to the diagnosis of Alzheimer disease (AD), they may not be specific. Relatively little is known about how they correlate with each other. Purpose: To identify the validity of the radiological linear measurements of brain atrophy in AD diagnosis by examining the correlation with CSF biomarke
Background. The definition of a "difficult" cannulation varies considerably in reports of endoscopic retrograde cholangiopancreatography (ERCP). Aims. To define a difficult cannulation, which translates into higher risk of post-ERCP pancreatitis. Patients and methods. Prospective consecutive recording of 907 cannulations in Scandinavian centers done by experienced endoscopists. Inclusion: indicati
Land degradation is always With Lis but its causes, extent and severity are contested. We define land degradation as a long-term decline in ecosystem function and productivity, Which may be assessed using lone-term, remotely sensed normalized difference vegetation index (NDVI) data. Deviation from the norm may serve as a proxy assessment of land degradation and improvement - if other factors that
The electronic structure of genomic DNA has been comprehensively characterized by synchrotron-based X-ray absorption and X-ray photoelectron spectroscopy. Both unoccupied and occupied states close to the Fermi level have been unveiled and attributed to particular sites within the DNA structure. A semiconductor-like electronic structure with a band gap of approximately 2.6 eV has been found at whic
Popular Abstract in Swedish Små, trådlösa och portabla apparater utgör idag en stor del av vår uppkopplade värld. Under det senaste decenniet har dock flera teknologiska framsteg lett mot en utveckling där allt från maskiner till kläder kommunicerar med varandra. Detta brukar kallas för "sakernas internet" och uppskattas involvera 50 miljarder enheter år 2020. Genom att förse dessa enheter med småThe modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuous-time Delta-Sigma mod
This paper investigates the relationship between history and national identity, specifically how “golden ages” in a nation’s past are used for nationalist ends. Using discourse analysis, it examines how two types of popular historical venues, museums and textbooks, present Japan’s Heian period (794-1185) and explores what this reveals about Japanese national identity formation. The Heian era has a
Objective IBS shows genetic predisposition, but adequately powered gene-hunting efforts have been scarce so far. We sought to identify true IBS genetic risk factors by means of genome-wide association (GWA) and independent replication studies. Design We conducted a GWA study (GWAS) of IBS in a general population sample of 11 326 Swedish twins. IBS cases (N=534) and asymptomatic controls (N=4932) w
To develop long-term high quality communication between brain and computer, a key issue is how to reduce the adverse foreign body responses. Here, the impact of probe flexibility and gelatine embedding on long-term (6w) tissue responses, was analyzed. Probes of same polymer material, size and shape, flexible mainly in one direction, were implanted in rat cerebral cortex (nimplants = 3 x 8) in two
Experimental work in turbid media has shown that transillumination images can be significantly improved by limiting light collection to a subset of photons which are minimally distorted by scattering. The literature details numerous schemes (commonly termed ballistic imaging), most often based on time-gating and/or spatially filtering the detected light. However, due to the complex nature of the d
After 50 years the Alliance for Progress was launched, the policies for territorial planning in Latin America have proved to fail. The WB and the IADB, instruments of the US international politics for the consolidation of its global and regional hegemony, are its main financial and doctrinaire sources. These agencies’ logics prevail in the general and territorial planning. In the aftermath of the
This study presents how a TiO2(B) film exposing the (001) face can be grown on Au(111) by chemical vapor deposition. Identification and characterization of the TiO2(B)(001) layer are carried out with low-energy electron diffraction (LEED), synchrotron radiation photoelectron spectroscopy (PES), scanning tunneling microscopy (STM) and X-ray absorption spectroscopy (XAS). Formation of the TiO2(B) fi
The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages, using data on Swedish manufacturing firms from 1997 to 2007. First, we investigate the productivity ordering with respect to three international linkages; importing, exporting and investing abroad. Second, we explore whether differences in the productivity ordering ac
By employing metal salts in dilute-acid pretreatment the severity can be reduced due to reduced activation energy. This study reports on a dilute-acid steam pretreatment of spruce chips by addition of a small amount of ferrous sulfate to the acid catalyst, i.e., either SO(2), H(2)SO(3) or H(2)SO(4). The utilization of ferrous sulfate resulted in a slightly increased overall glucose yield (from 74%
Making use of 36 pb(-1) of proton-proton collision data at root s = 7 TeV, the ATLAS Collaboration has performed a search for diphoton events with large missing transverse energy. Observing no excess of events above the Standard Model prediction, a 95% Confidence Level ( CL) upper limit is set on the cross section for new physics of sigma < 0.38-0.65 pb in the context of a generalised model of gau
Lipoprotein-associated phospholipase A2 (Lp-PLA2) is today considered a novel specific vascular inflammatory biomarker. The general aim of this thesis was to study the role and impact of Lp-PLA2 as cardiovascular (CV) risk marker in an epidemiologic perspective. Specific aims were to explore the cross-sectional association of Lp-PLA2 with traditional CV risk factors, to asses the genetic influence
Popular Abstract in Swedish Hjärt- och kärlsjukdomar är idag den vanligaste dödsorsaken i stora delar av världen för både män och kvinnor. I Sverige är hjärtinfarkt den vanligaste dödsorsaken för kvinnor över 55 år och för män över 45 år. Det vill säga kvinnor drabbas cirka 10 år senare. Tidigare forskning har baserats i huvudsak på män varvid forskning på kvinnor med hjärt- och kärlsjukdomar har Background: Coronary heart disease (CHD) is the sleading cause of mortality in men and women in Western society. Few studies of CHD have been performed on women or with a focus on cardiac risk factors in women’s lives. Results from studies of men have been generalized to women, which may be inappropriate or even dangerous. Aim: The overall aim of this thesis was to describe women’s experience of a
The mystacocarid crustacean Derocheilocaris typica Pennak and Zinn, 1943 lives in sand interstices and is less than one mm long. It is unique among Arthropoda. It has sensory cells in the mandible, which lack cilia. The function as mechano- and/or chemo-receptors has been replaced by dendrites, the sensory cell protrusions carrying cilia. The dendrites swell, flatten, and fill the endite- a medial
