Immune response to Mycoplasma pneumoniae P1 and P116 in patients with atypical pneumonia analyzed by ELISA

Background: Serology is often used for the diagnosis of Mycoplasma pneumoniae. It is important to identify specific antigens that can distinguish between the presence or absence of antibodies against M. pneumoniae. The two proteins, P116 and P1, are found to be immunogenic. By using these in ELISA it is possible to identify an immune response against M. pneumoniae in serum samples. Results: A reco

Conductance of GABAA channels activated by pentobarbitone in hippocampal neurons from newborn rats

Neurons were obtained from the CA1 region of the hippocampus of newborn rats and maintained in culture. Channels were activated by pentobarbitone in cell-attached, inside-out or outside-out patches, normally by applying pentobarbitone in flowing bath solution. Currents were outwardly rectifying and blocked by bicuculline, properties of GABAA channels in these cells. Maximum channel conductance inc

Investigation of colour reconnection in WW events with the DELPHI detector at LEP-2

In the reaction e(+)e(-) -> WW -> (q(1) (q) over bar (2))(q(3)(q) over bar (4)) the usual hadronization models treat the colour singlets q(1)(q) over bar (2) and q(3)(q) over bar (4) coming from two W bosons independently. However, since the. nal state partons may coexist in space and time, cross-talk between the two evolving hadronic systems may be possible during fragmentation through soft gluon

Environmentally Friendly Disposal Behaviour and Local Support Systems: lessons from a metropolitan area.

The amount of household refuse has steadily increased in Sweden and this is consistent with the trend in the rest of the European Union. Strategies for household waste reduction includes sorting, recycling, re-use and repair. Two categories of motivational factors determine disposal behaviour, external and internal. The external factors include administrative, economic, information and physical me

The Sami People in Scandinavia: Government Policies for Indigenous Language Recognition and Support in the Formal Education System

The Sámi people in Scandinavia have experienced a long history of discrimination, oppression, neglect, ridicule, and theft. Some scholars compare the history of the Sámi with that of the American Indian population. Today the Sámi who live in Sweden, Norway and Finland, together with the Sámi in Russia have managed to improve their situation through concerted efforts, collaboration with one another

Numerical simulations of heat transfer and fluid flow for a rotating high-pressure turbine

In this work, a numerical study has been performed to simulate the heat transfer and fluid flow in a transonic high-pressure turbine stator vane passage. Four turbulence models (the Spalart-Allmaras model, the low-Reynolds-number realizable k-ε model, the shear-stress transport (SST) k-ω model and the v2-f model) are used in order to assess the capability of the models to predict the he

Synthetic Galectin Inhibitors Selective O-galactosyl aldoximes, multivalent lactosides and galactose-mimicking mannosides

Popular Abstract in Swedish Galektin är en proteinfamilj med många funktioner i kroppen, varav en del är kopplade till sjukdomstillstånd, såsom inflammationer samt utvecklandet och fortskridandet av cancer. Galektiners funktion styrs av en kolhydratbindande domän (CRD) som känner igen och binder till galaktos. Vissa galektiner kan hålla ihop olika celler genom att binda till galaktos på cellytor.This thesis describes the design, synthesis and evaluation of synthetic inhibitors for the carbohydrate binding proteins called galectins. Potent and selective inhibitors can be used as important research tools in the endeavor to chart the true role of galectins in biological events such as cancer and inflammation and possibly as lead for future galectin targeting drugs. A panel of O-galactosyl a

Cooperation Between Library and Teaching and Learning – What ́s the Use?

At Lund University Faculty of Technology a growing number of teachers develop active student learning methods. These methods can have some advantages in obtaining certain objectives with higher education. To take responsibility for the own learning process and also to learn how to independently handle information and use it in an adequate way are important skills to achieve during an university ed

Increased focus on values. A tool in stress prevention?

Background and purpose Can an increased focus on values in working life be a factor in stress prevention? Values are defined as the shared principles which guide behaviour in an organisation. The purpose of this study was to describe how patients with musculoskeletal pain perceive the importance of values in relation to coping with daily stress and in relation to health. Methods Patients receivi

Interactions between charged polypeptides and nonionic surfactants

The influence of molecular characteristics on the mutual interaction between peptides and nonionic surfactants has been investigated by studying the effects of surfactants on amphiphilic, random copolymers of alpha-L-amino acids containing lysine residues as the hydrophilic parts. The hydrophobic residues were either phenylalanine or tyrosine. The peptide-surfactant interactions were studied by me

Application of supercritical carbon dioxide for the extraction of alkylresorcinols from rye bran

The use of supercritical CO, (SC-CO2) for extracting alkylresorcinols from rye bran was investigated. For pure SC-CO2, 35 MPa and 55 degrees C were used. SC-CO2 with 10% ethanol or methanol as co-solvents was tested at four pressure levels (8, 15, 30 and 35 MPa) and two temperatures (40 and 55 degrees C). Experiments were conducted at a constant SC-CO2 flow of 5 g/min for 2 h. For comparative purp

An analysis of the analysis of herbivore population dynamics

Time series analysis of herbivore data with weather included as covariate is commonly used as a mean to shed light on the state and ecology of the studied population. Conclusions about the herbivore population are drawn from statistical parameter values and presence/absence in the most parsimonious model. However, this procedure is only reliable if the statistical parameters have general interpret

Evaluation of a sulfophenylated polysulfone membrane in a fuel cell at 60 to 110 °C

A novel sulfophenylated polysulfone membrane material has been evaluated in a hydrogen/oxygen fuel cell using Nafion-impregnated commercial electrodes. Comparative measurements were performed with Nafion membranes to distinguish between different sources of potential losses. The operational temperatures in the experiments ranged from 60 to 110 °C, and the effect of different humidifying conditions

Hydroxyl radical consumption following photolysis of vapor-phase hydrogen peroxide at 266 nm: Implications for photofragmentation laser-induced fluorescence measurements of hydrogen peroxide

The decay of OH concentration following photolysis of room-temperature vapor-phase hydrogen peroxide is studied as a function of photolysis fluence at 266 nm in an open air environment. The rate of decay is found to increase with increasing photolysis fluence, i.e., with increasing number of photodissociated H2O2(g) molecules. Single-exponential functions approximate the OH concentration decay rat

Data fitting and image fine-tuning approach to solve the inverse problem in fluorescence molecular imaging

One of the most challenging problems in medical imaging is to ``see{''} a tumour embedded into tissue, which is a turbid medium, by using fluorescent probes for tumour labeling. This problem, despite the efforts made during the last years, has not been fully encountered yet, due to the non-linear nature of the inverse problem and the convergence failures of many optimization techniques. This paper

Diagnosing and treating Diamond Blackfan anaemia: results of an international clinical consensus conference

Diamond Blackfan anaemia (DBA) is a rare, genetically and clinically heterogeneous, inherited red cell aplasia. Classical DBA affects about seven per million live births and presents during the first year of life. However, as mutated genes have been discovered in DBA, non-classical cases with less distinct phenotypes are being described in adults as well as children. In caring for these patients i

Dual-window scatter correction and energy window setting in cerebral blood flow SPECT: a Monte Carlo study

The image quality in SPECT studies of the regional cerebral blood flow (rCBF) performed with 99mTc-HMPAO is degraded by scattered photons. The finite energy resolution of the gamma camera makes the detection of scattered photons unavoidable, and this is observed in the image as an impaired contrast between grey and white matter structures. In this work, a Monte Carlo simulated SPECT study of a rea
