Endoscopic assessment and grading of Barrett's esophagus using magnification endoscopy and narrow band imaging: Impact of structured learning and experience on the accuracy of the Amsterdam classification system

Objective. Several classification systems have been launched to characterize Barrett's esophagus (BE) mucosa using magnification endoscopy with narrow band imaging (ME-NBI). The good accuracy and interobserver agreement described in the early reports were not reproduced subsequently. Recently, we reported somewhat higher accuracy of the classification developed by the Amsterdam group. The critical

A pre-sample charge measurement system for quantitative NMP-analysis

In many IBA applications the main aim is to obtain quantitative figures characterizing the sample. Normally charge, i.e. number of probe particles, is used for normalization and is measured either by collecting the charge deposited in the sample or by collecting the particle in a post-sample Faraday cup or in combination. Both these techniques have drawbacks and results can be difficult to compare

Arterial dysfunction but maintained systemic blood pressure in cavin-1-deficient mice.

Caveolae are omega-shaped plasma membrane micro-domains that are abundant in cells of the vascular system. Formation of caveolae depends on caveolin-1 and cavin-1 and lack of either protein leads to loss of caveolae. Mice with caveolin-1 deficiency have dysfunctional blood vessels, but whether absence of cavin-1 similarly leads to vascular dysfunction is not known. Here we addressed this hypothesi

Gut Manifestations in an Experimental Model of Multiple Sclerosis

Multiple sclerosis (MS) is an immune-mediated demyelinating and neurodegenerative disease of the central nervous system (CNS). Neuroinflammatory processes in MS are believed to lead to damage and leakage in the blood-brain barrier that protects the CNS and regulates the trafficking of soluble mediators and leukocytes. MS is thought to be triggered in genetically susceptible individuals following e

BACQUIN, MARI, Theseus de Cologne, édition partielle d’une chanson de geste du XIVe siècle. Études romanes de Lund, 81, 355 pages. Written in French. Monograph. Theseus de Cologne is a French romance from the fourteenth century written by an anonymous author. This voluminous work contains more than 26,000 lines. The text of the romance is preserved in three manuscripts from the fifteenth century,

Hematopoietic Stem Cells Are Intrinsically Protected against MLL-ENL-Mediated Transformation.

Studies of developmental pathways of hematopoietic stem cells (HSCs) have defined lineage relationships throughout the blood system. This is relevant to acute myeloid leukemia (AML), where aggressiveness and therapeutic responsiveness can be influenced by the initial stage of transformation. To address this, we generated a mouse model in which the mixed-lineage leukemia/eleven-nineteen-leukemia (M

Remission maintenance in acute myeloid leukemia: impact of functional histamine H-2 receptors expressed by leukemic cells

Post-consolidation immunotherapy with histamine dihydrochloride and interleukin-2 has been shown to improve leukemia-free survival in acute myeloid leukemia in a phase III trial. For this study, treatment efficacy was determined among 145 trial patients with morphological forms of acute myeloid leukemia as defined by the French-American-British classification. Leukemia-free survival was strongly i

Detection by near-infrared spectroscopy of large lipid cores at culprit sites in patients with non-st-segment elevation myocardial infarction and unstable angina

ObjectiveThis study was performed to assess the lipid burden of culprit lesions in non-ST-segment elevation myocardial infarction (non-STEMI) and unstable angina (UA). BackgroundA recent intracoronary near-infrared spectroscopy (NIRS) study showed 85% of STEMI culprit lesions have a maximum lipid core burden index in 4-mm (maxLCBI(4mm))400. Whether culprit lesions in non-STEMI and UA are character

Towards a theological virtue ethic for the preservation of biodiversity

In this paper I discuss how a virtue ethic for the preservation of biodiversity may look like. The starting-point is the virtue ethic proposed by Celia Deane-Drummond. She suggests that the four cardinal virtues of prudence, justice, fortitude and temperance should form the basis of an ethic of nature. Of this four, prudence is the most fundamental. Moreover, Deane-Drummond states that the intelle

Jordar - teknologi - aktörer. Några tankar om bebyggelse och odling kring Lund och Uppåkra i övergången mellan yngre järnålder och tidig medeltid.

Artikeln diskuterar samspelet mellan jordarter, teknologi och "aktörer" och dessa olika faktorers betydelse för bebyggelseutvecklingen. I huvudsak diskuteras utvecklingen av landskapet och bebyggelsen kring Lund och Uppåkra i Skåne (Torna härad och delar av Bara härad). Exempel hämtas även från området kring Skälderviken och en del av Söderåsen (Björnekulla). Artikeln argumenterar för att forsknin

The Caloplaca holocarpa group in the Nordic countries, except Iceland

The Caloplaca citrina group in the Nordic countries, except Iceland, is analysed with regard to morphology, anatomy, ecology, and chemistry. Their genetic relationship is also analysed using the ITS ribosomal DNA gene. The results show that there are at least five species within what has been called C. citrina, of which four are closely related to one another and to several non-sorediate species.

The Ca2+-Regulation of the Mitochondrial External NADPH Dehydrogenase in Plants Is Controlled by Cytosolic pH.

NADPH is a key reductant carrier that maintains internal redox and antioxidant status, and that links biosynthetic, catabolic and signalling pathways. Plants have a mitochondrial external NADPH oxidation pathway, which depends on Ca2+ and pH in vitro, but concentrations of Ca2+ needed are not known. We have determined the K0.5(Ca2+) of the external NADPH dehydrogenase from Solanum tuberosum mitoch

Household salt as an emergency radiation dosemeter for retrospective dose assessments using optically stimulated luminescence

Popular Abstract in Swedish Personer som arbetar med joniserande strålning inom t.ex. sjukvård, kärnteknik och forskning använder så kallade dosimetrar för att registrera hur mycket joniserande strålning (vilken stråldos) personen blivit utsatt för under ett arbetspass eller en arbetsmånad. Den stråldos som en dosimeter mäter ger ett mått på risken för eventuella sena hälsoeffekter i form av en ökIn the event of a radiation accident, it is crucial to make rapid estimates of the absorbed dose received by both emergency workers, so-called first responders, and members of the public. Today, only personnel in rescue teams responding to nuclear emergencies have access to individual dosemeters. To make accurate assessments of the radiological consequences of an emergency situation, methods of re
