Background: Assessing left ventricular (LV) dysfunction by echocardiography in ICU patients is common. The aim of this study was to investigate mitral annular plane systolic excursion (MAPSE) in critically ill patients with shock and its relation to LV systolic and diastolic function, myocardial injury and to outcome. Methods: In a prospective, observational, cohort study we enrolled 50 patients w

Accurately reconstructing the rate of movement and extent of eolian dunes over thousands of years is a challenging endeavor. In this paper, we refine the methodology for utilizing lakes and bogs downwind of dune fields as precise recorders of past eolian activity. Sediment cores from two Allegan County lakes and one bog associated with dunes were studied to evaluate the importance of the various s

The aim of the present study was to explore the ability of personality to predict academic performance in a longitudinal study of a Swedish upper secondary school sample. Academic performance was assessed throughout a three-year period via final grades from the compulsory school and upper secondary school. The Big Five personality factors (Costa & McCrae, 1992) - particularly Conscientiousness

The use of performance enhancing drugs, especially anabolic androgenic steroids (AAS) has emerged as a social problem outside competitive sports, linked to substance abuse and crime. The purpose of this article is to analyze the use of doping and attitudes to doping outside the competitive sports context in relation to age, gender, ethnicity, so¬cio-economic status, and branch of sport. The articl

Unlike many nanomaterials, nanocrystalline cellulose (CNC) is not synthesized from molecular or atomic components but rather extracted from naturally occurring cellulose. Undoubtedly, the exploitation of CNCs will become a bridge between nanoscience and natural resource products, which could play a major role in reviving the forest industry. In this work, CNC was successfully extracted from unusua

To assess HCV viremia levels just before, during and one year after anti-HCV seroconversion in people who inject drugs (PWID).

S100A8 and S100A9 are Ca(2+)-binding proteins that are associated with acute and chronic inflammation and cancer. They form predominantly heterodimers even if there are data supporting homodimer formation. We investigated the stability of the heterodimer in myeloid and S100A8/S100A9 over-expressing COS cells. In both cases, S100A8 and S100A9 proteins were not completely degraded even 48 hrs after

The main objective of this thesis was to quantitatively estimate the gaseous exchange of carbon dioxide (CO2) and methane (CH4) between a subarctic wetland ecosystem and the atmosphere. Additionally some initial estimates of the carbon input to the atmosphere of nonmethane hydrocarbons (NMHCs) were also obtained by combining different techniques in a joint setting. The data presented were collecte

Popular Abstract in Swedish Vad triggar kunskapsprocesser och kunskapsstrategier i projektbaserade organisationer? Sofia Pemsel, Institutionen för Byggvetenskaper, Lunds Tekniska Högskola. Inledning Vad avgör om en organisation har välutvecklade och fungerande kunskapsprocesser och färdigheter eller inte? Varför är vissa organisationer fantastiska på kundhantering medans andra är fenomenala i teThe beauty of projects lies in their ability to integrate different knowledge bases and expertise in novel ways. Projects, though, are temporary in nature and this has consequences for the organization that uses them as a business strategy to improve its efficiency. Project-based organizations are representative of this organizational form and can either be standalone or subsidiary organizations w

Protein glycosylation has significant effects on the structure and function of proteins. The efficient separation and enrichment of glycoproteins from complex biological samples is one key aspect and represents a major bottleneck of glycoproteome research. In this paper, we have explored pH multimodal hydrophobic interaction chromatography to separate glycosylated from non-glycosylated forms of pr

We report an electron-beam based method for the nanoscale patterning of the poly(ethylene oxide)/LiClO4 polymer electrolyte. We use the patterned polymer electrolyte as a high capacitance gate dielectric in single nanowire transistors and obtain subthreshold swings comparable to conventional metal/oxide wrap-gated nanowire transistors. Patterning eliminates gate/contact overlap, which reduces para

BACKGROUND: Postmenopausal hormone therapy (HRT) and oral contraceptive (OC) use have in several studies been reported to be associated with a decreased colorectal cancer (CRC) risk. However, data on the association between HRT and OC and risk of different clinicopathological and molecular subsets of CRC are lacking. The aim of this molecular pathological epidemiology study was therefore to evalua

ABSTRACT: BACKGROUND: Two-step dilute acid hydrolysis of softwood, either as a stand-alone process or as pretreatment before enzymatic hydrolysis, is considered to result in higher sugar yields than one-step acid hydrolysis. However, this requires removal of the liquid between the two steps. In an industrial process, filtration and washing of the material between the two steps is difficult, as it

Recent large-scale cDNA cloning studies have shown that a significant proportion of the transcripts expressed from vertebrate genomes do not appear to encode protein. Moreover, it was reported in mammals (human and mice) that these non-coding transcripts are expressed and regulated by mechanisms similar to those involved in the control of protein-coding genes. We have produced a collection of cDNA

The welding of dissimilar alloys is seen increasingly as a way forward to improve efficiencies in modern aeroengines, because it allows one to tailor varying material property demands across a component. Dissimilar inertia friction welding (IFW) of two high-strength steels, Aermet 100 and S/CMV, has been identified as a possible joint for rotating gas turbine components and the resulting welds are

The usage of industrial robots for milling tasks is limited by their lack of absolute accuracy in presence of process forces. While there are techniques and products available for increasing the absolute accuracy of free-space motions, the mechanical weaknesses of the robot in combination with the milling forces limits the achievable performance. If the dynamic effects causing the deviations can b

Investigations of past fires suggest that building occupants faced with a fire have problems defining the severity of it, especially in the early stages of the fire. An experiment was therefore carried out to study people’s ability to estimate fire growth, and their perceived ability to extinguish a fire using a portable fire extinguisher. A total of 535 persons, namely 304 men and 231 women, were

Popular Abstract in Swedish Njurfunktion inom hjärtkirurgi Akut njursvikt (AKI) efter hjärtkirurgi är en allvarlig komplikation som förekommer i 25-35 % av alla patientfall. AKI medför förhöjd risk för allvarliga komplikationer och död efter hjärtkirurgi. Ett stort fokus ligger på detektion, prevention och behandling av AKI och forskningsfältet uppdateras kontinuerligt. En rad olika läkemedel har Abstract Acute kidney injury (AKI) is a common and serious complication after cardiothoracic surgery and is associated with increased short- and long-term mortality risk. Despite extensive studies in the field, a comprehensive understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and partly due to the limitations of available routine biomarkers to predict,
