Disturbances in swallowing are common in neurologic disease but difficult to evaluate in the clinical setting. Fundamental variables such as bolus volume, swallow capacity (volume ingested over time), and the relation between ingestion and time for important events in oral and pharyngeal swallowing have not been sufficiently studied. We therefore employed a composite method for monitoring oral and
BACKGROUND: Middle-aged women experience various health-related problems. The aim of this study was to evaluate the impacts of menopause status and hormone intervention on women's health. METHODS: In an ongoing, population-based study, 4943 women, born 1935 to 1945 and living in the Lund area of Southern Sweden, were included in this analysis. They completed a generic questionnaire pertaining to s
We analyzed the concentration of I-129 in the water of 26 rivers covering most of the runoff from Sweden, with the aim of assessing current contamination levels, distribution patterns and potential sources in freshwater systems of northern Europe. The results show relatively high values (up to 1.4 x 10(9) atoms 1(-1)), steeply decreasing levels with increasing latitude and a positive correlation w
A swallow flying in the Lund wind tunnel was observed from the side and from behind, by two synchronised highspeed video cameras. The side-view camera provided a record of the vertical position of a white mark, applied to the feathers behind and below the eye, from which the vertical acceleration was obtained. The rear-view camera provided measurements of the mean angle of the left and right humer
Objectives: To describe and compare the methods of pain management used by elderly individuals with chronic pain and requiring assistance with activities of daily living, depending on whether they live alone, with someone, at home or in special accommodations. Methods: This study comprised 294 people aged 76–100 years, identified as having chronic pain and requiring assistance with activities of
An analytical procedure based on supercritical-fluid extraction and microwave-assisted extraction was applied on six different real leather samples for the determination of banned azo dyes. Determination of the dyes was performed indirectly by measuring their corresponding harmful aromatic amines, formed after reduction. A comparative study between external standard calibration and standard additi
Local inflammatory reactions affect the integrity of intestinal epithelial cells, such as E-cadherin-mediated cell-cell interactions. To elucidate this event, we investigated the effects of an inflammatory mediator, leukotriene D(4 )(LTD(4)), on the phosphorylation status and properties of vinculin, a multi-binding protein known to interact with both the E-cadherin-catenin complex and the cytoskel
Because of their limited size and complexity, de novo designed proteins are particularly useful for the detailed investigation of folding thermodynamics and mechanisms. Here, we describe how subtle changes in the hydrophobic core of a model three-helix bundle protein (GM-0) alter its folding energetics. To explore the folding tolerance of GM-0 toward amino acid sequence variability, two mutant pro
Abstract 10.1002/dvdy.20997.abs In mammals, the anti-Müllerian hormone (Amh) is responsible for the regression of the Müllerian ducts; therefore, Amh is an important factor of male sex differentiation. The amh gene has been cloned in various vertebrates, as well as in several teleost species. To date, all described species show a sexually dimorphic expression of amh during sex differentiation or a
Barnase folds cooperatively via an intermediate, followed by a rate-limiting transition state. We have probed possible movements of the intermediate and transition state on the energy landscape with changing temperature, from the temperature dependence of -values. These measure interaction energies at the level of individual residues. The results suggest that single destabilizing mutations can red
The respiratory gas exchange and ventilation during an incremental cycle exercise test were analysed in a group of 19 healthy, moderately fit men. Different computer algorithms were used to estimate the VO2 values where: (i) the rate of VCO2 increase just exceeds the rate of VO2 increase (DX, derivative crossing), (ii) VCO2/VO2 = 1·00 (PX, point of crossing) and (iii) ventilation (VE) increases di
Particle image velocimetry is applied to measure the vertical (r-z) plane flow structures in a light-duty direct-injection diesel engine with a realistic piston geometry. The measurements are corrected for optical distortions due to the curved piston bowl walls and the cylindrical liner. Mean flow fields are presented and contrasted for operation both with and without fuel injection and combustion
The relationships between dispersal and local transmission rate of parasites are essential to understanding host-parasite coevolution and the emergence and spread of novel disease threats. Here we show that year-round transmission, as opposed to summer transmission, has repeatedly evolved in malarial parasites (genera Plasmodium and Haemoproteus) of a migratory bird. Year-round transmission allows
Objective. To clarify the spontaneous course of important disease manifestations (a core set of outcome measures) over a period of 5 years in patients with primary Sjögren's syndrome (SS), and to analyze predictors of unfavorable outcome. To test the usefulness of the recently proposed core set of outcome measures. Methods. A cohort of patients with primary SS according to the American-European c
