OBJECTIVE: Pressure-volume (PV) curves are recorded after induction of complete muscle paralysis, which may limit their clinical use. The feasibility of recording PV curves without paralysis has not been tested. In 19 patients with acute respiratory distress syndrome (ARDS) and no hemodynamic instability we prospectively evaluated whether PV curves can be safely and reliably recorded under deep se
The impact of the optical properties on the annual performance of flat plate collectors in a Swedish climate has been estimated with the MINSUN program. The collector parameters were determined with a theoretically based calculation program verified from laboratory measurements. The importance of changes in solar absorptance and thermal emittance of the absorber, the addition of a teflon film or a
Objective Most epidemiologic studies have suggested an increased risk of breast cancer with increasing alcohol intake. Using data from 274,688 women participating in the European Prospective Investigation into Cancer and Nutrition study (EPIC), we investigated the relation between alcohol intake and the risk of breast cancer. Methods Incidence rate ratios (IRRs) based on Cox proportional hazard mo
Pili of Neisseria gonorrhoeae mediate binding of the bacteria to human host cells. Membrane cofactor protein (MCP or CD46), a human cell-surface protein involved in regulation of complement activation, acts as a cellular pilus receptor. In this work, we examined which domains of CD46 mediate bacterial adherence. The CD46 expression was quantified and characterized in human epithelial cell lines. N
It has been suggested that secondary sexual ornamentation signals male ability to resist infections, as only high-quality individuals are able to invest both in high immune defence and elaborate ornament expression. Such ornaments could thus serve as indicators of male quality and could be used by females in choosing mates. Ostriches are sexually dimorphic with regard to coloration of their feathe
The purpose of this study was to investigate the validity of the Irena Daily Activity (IDA) assessment which measures occupational performance in adults with developmental disabilities. The instrument's content validity was investigated by elucidating its general appropriateness, its clinical applicability and the feasibility of the measurement procedure. Data were collected from a multidisciplina
Production of reactive oxygen and nitrogen species (ROS/RNS) is an important part of the inflammatory response, but prolonged elevated levels of ROS/RNS as under chronic inflammation can contribute to the development of disease. Monitoring ROS/RNS in living animals is challenging due to the rapid turnover of ROS/RNS and the limited sensitivity and specificity of ROS/RNS probes. We have explored th
Defective assembly of alpha 3 alpha 4 alpha 5(IV) collagen in the glomerular basement membrane causes Alport syndrome, a hereditary glomerulonephritis progressing to end-stage kidney failure. Assembly of collagen IV chains into heterotrimeric molecules and networks is driven by their noncollagenous (NC1) domains, but the sites encoding the specificity of these interactions are not known. To identi
The separation and characterization of salivary mucins is not straightforward because of their large size, heterogeneity, and molecular interactions. The MUC5B and MUC7 mucins are major glycoprotein components of saliva that are thought to play a vital role in maintaining oral health. MUC5B is also a major component of respiratory mucus and is produced by the tracheal and bronchial glands, while M
This paper focuses on challenges in implementation of research in community-based occupational therapy practice. Based on a two-year project in a south Swedish municipality aiming at studying implementation of structured assessment procedures in the housing adaptation process, the first purpose is to provide a detailed project description, and the second is to report on first results identifying c
Summary The leaking of water through roofs is a major problem in many parts of Tunisia. As a part of a collaboration between "École N: ionale d'Ingénieurs de Tunis" (E.N.I.T.) and Lund University, Institute of Science and Technology (L.N.T.H.), Sweden, a measuring method has been developed to compare the watertightness of different roofing membranes. With the method, three roof structues with diff
BACKGROUND: The S-s-U- phenotype in African Americans is due to a GYPB deletion, however the molecular basis for the S-s-U+var phenotype is poorly understood. Variable reactivity of S-s-U+var RBCs with monoclonal anti-He or by anti-U has been demonstrated, however the underlying molecular bases for this phenotype remain to be established. STUDY DESIGN AND METHODS: Hemagglutination was performed on
The fate of ornithine in the nephron of the female OF-1 Swiss mouse remains unknown. The aim of the present study was to identify the nephron segments containing the key enzymes involved in ornithine metabolism: ornithine decarboxylase (ODC) and ornithine aminotransferase (OAT). Viable tubules isolated by microdissection were incubated with [1-14C]ornithine to study the oxidative pathway. Other tu
In 1995 and 1996 a Swedish feed mill had problems due to a persistent contamination of Salmonella enterica spp. enterica serovar Senftenberg that was difficult to eliminate. Forty-eight strains isolated from the feed mill, together with unrelated strains included to evaluate the discriminatory power and reproducibility, were analysed by pulsed-field gel electrophoresis (PFGE). The source of contam
It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin
This dissertation argues that the English Protestant interpretations between 1845 and 1864 of John Henry Newman’s secession were related to the notions which formed part of the British national identity. It demonstrates how various writers modelled their interpretations of Newman’s secession on the beliefs of British anti-Catholicism. By understanding the British national identity as a common cult
BACKGROUND: Colorectal cancer (CRC) is one of the most common causes of cancer-related deaths in the Western world, and despite the fact that metastases are usually the ultimate cause of deaths, the knowledge of the genetics of advanced stages of this disease is limited. In order to identify potential genetic abnormalities underlying the development of local and distant metastases in CRC patients,
The effect of warmer climate on the depletion of snow-covered area has been evaluated for the Satluj River basin located in the western Himalayan region in India. Snowmelt runoff contributes substantially to the annual streamflow of this river. In order to study the impact of three warming scenarios (T+1, T+2 and T+3degreesC), more than 160 new snow depletion curves were prepared for different ele
Helicobacter pylori exists in two different morphological forms, spiral and coccoid. This study demonstrated that both forms can infect BALB/c A mice. The animals were inoculated orally three times at 2-day intervals with 10(8) cfu of both spiral and coccoid forms of strain CCUG 17874 (NCTC 11637), strain 25 and strain 553/93. Infection was followed over a 30-week period by histological scoring of
