Background Following oesophagectomy, a major surgical procedure, it is known that patients suffer from severely reduced quality of life and have an unmet need for postoperative support. Still, there is a lack of research testing interventions aiming to enhance the patients’ life situation after this surgical procedure. Aim The aim of the study was to evaluate the effect of a nurse led telephone su

Provupparbetning är ett viktigt steg i många metoder för kemisk analys.Detta gäller framförallt fasta prover då de kemiska ämnena som avses för analys, även kallade analyter, måste extraheras ut. Det vill säga att genomföra en överföring av analyter från provet till ett lösningsmedel. Därefter kan halten bestämmas med de metoder som ofta finns till hands i ett analyslaboratorium. I de fall då fettSupercritical fluid extraction is an extraction technique suitable for lipophilic compounds from solid samples. Most commonly supercritical carbon dioxide is the main component in the extraction phase, rendering the technique relatively environmentally benign. The extraction technique is rapid due to the low viscosity and the high diffusivity of analytes in the supercritical extraction phase.The s

Background: Asthmatic patients have higher microbiome diversity and an altered composition, with more Proteobacteria and less Bacteroidetes compared with healthy control subjects. Studies comparing airway inflammation and the airway microbiome are sparse, especially in subjects not receiving anti-inflammatory treatment. Objective: We sought to describe the relationship between the airway microbiom

Aim and objective: To describe and understand the meaning of living with persistent rheumatoid arthritis. Background: A considerable number of patients with rheumatoid arthritis live with an ongoing active and symptomatic illness despite access to potent antirheumatic treatment. There is, however, a lack of knowledge about the meaning of living with this severe long-term illness, defined as persis

The endogenous C18 N-acylethanolamines (NAEs) N-linolenoylethanolamine (18:3 NAE), N-linoleoylethanolamine (18:2 NAE), N-oleoylethanolamine (18:1 NAE), and N-stearoylethanolamine (18:0 NAE) are structurally related to the endocannabinoid anandamide (20:4 NAE), but these lipids are poor ligands at cannabinoid CB1 receptors. Anandamide is also an activator of the transient receptor potential (TRP) v

Atmospheric air samples were taken within 3 km from power plants encompassing five different distances and wind directions. Samples were taken between 2002 and 2005 aiming to evaluate the environmental C-14 enrichment due to the operation of Brazilian nuclear power plants. The sampling system consisted of a pump connected to a trapping column filled with a 3 M NaOH solution. The trapped C-14 by us

OBJECTIVES: This study determined whether performance in neurobehavioral tests deteriorates during subjectively annoying chemical challenge below known neurotoxic thresholds among persons with toxic encephalopathy with subjective hypersensitivity to chemicals. METHODS: Subjects with symptoms and previous neuropsychological test results compatible with toxic encephalopathy (TE) of either type 2A (

The DyDOC model simulates the C dynamics of forest soils, including the production and transport of dissolved organic matter (DOM), on the basis of soil hydrology, metabolic processes, and sorption reactions. The model recognizes three main pools of soil C: litter, substrate (an intermediate transformation product), and humic substances. The model was used to simulate the behavior of C in the 0 ho

The expression of platelet-derived growth factor (PDGF) receptors in porcine uterus and human skin in situ, was compared with that of cultured primary cells isolated from the same tissues. PDGF receptor expression was examined by monoclonal antibodies specific for the B type PDGF receptor and by RNA/RNA in situ hybridization with a probe constructed from a cDNA clone encoding the B type PDGF recep

The purpose of this study was to investigate the relation between stuttering and a range of variables of possible relevance, with the main focus on neuromuscular reactivity, and anxiety. The explorative analysis also included temperament, biochemical variables, heredity, preonset lesions, and altered auditory feedback (AAF). An increased level of neuromuscular reactivity in stuttering adults has p

Dramatic changes occur in skin as a function of age, including changes in morphology, physiology, and mechanical properties. Changes in extracellular matrix molecules also occur, and these changes likely contribute to the overall age-related changes in the physical properties of skin. The major proteoglycans detected in extracts of human skin are decorin and versican. In addition, adult human skin

Reliable performance evaluation of wastewater treatment plants (WWTPs) can be done by simulating the plant behavior over a wide range of influent disturbances, including series of rain events with different intensity and duration, seasonal temperature variations, holiday effects, etc. Such simulation-based WWTP performance evaluations are in practice limited by the long simulation time of the mech

We investigated whether local biotic and abiotic conditions could explain the occurrence of calling males of the declining spadefoot toad Pelobates fuscus in 72 ponds in southern Sweden. The ponds covered the entire distribution range of P. fuscus and were monitored during the breeding season in 2000. Calling males were found in 33 ponds. representing ca 50% of all known ponds for the species ill

Objectives: To assess the prevalence of pharyngeal and oesophageal symptoms and dysmotility in patients with primary Sjogren's syndrome ( pSS) and relate these to autonomic nervous function. Methods: Twenty consecutive pSS patients, according to the American - European Consensus Criteria ( AECC), and 30 age- and sex- matched controls from the Swedish general population registry were studied. All s

Objective S100B is viewed as the most promising biomarker for brain damage. It has been proposed that this marker is useful in a Neurointensive Care Unit (NICU) as a monitoring parameter. This study aims to examine the clinical usefulness of daily serum S100B measurements in this setting. Design Prospective consecutive inclusion of patients. Patients A total of 79 patients with confirmed or suspec

Cystatin C, a major extracellular cysteine proteinase inhibitor, is deposited as amyloid in brain haemorrhage patients with hereditary cystatin C amyloid angiopathy (HCCAA). A disease-causing mutation on the genetic level results in the substitution Leu68-->Gln (L68Q) in cystatin C, which causes protein instability. Besides carrying the L68Q substitution, cystatin C in amyloid deposits isolated fr

Shoot uptake of mineral nutrients (Ca, Cu, Fe, K, mg, Mn, P, S, Zn) by Agrostis stolonifera L. was compared with Festuca ovina L. under wet and dry cycles. Such conditions are typical for A. stolonifera sites, whereas F. ovina is growing mostly on consistently drier and better-drained soils. Plants were grown in a glasshouse, at controlled temperature and light conditions, using two moisture regim

Ser72 at the active site of the Escherichia coli dUTPase has been mutated to an alanine, and the properties of the mutant have been investigated. The serine is absolutely conserved among the monomeric and trimeric dUTPases (including the bifunctional dCTP deaminase:dUTPases), and it has been proposed to promote catalysis by balancing negative charge at the oxygen that bridges the alpha- and beta-p
