Tendon injuries at the epicondyle can occur in athletes and workers whose job functions involve repetitive, high force hand activities, but the early pathophysiologic changes of tendon are not well known. The purpose of this study was to evaluate early tendon structural changes, specifically the formation of microtears, caused by cyclical loading. The Flexor Digitorum Profundus (FDP) muscle of nin

Aim: Obesity is associated with increased levels of inflammatory mediators. The objective of this study was to evaluate changes in the leucocyte derived inflammatory mediators tumour necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6) and the isoprostane 8-epi-prostaglandin (PG) F2alpha during BMI lowering with orlistat (Xenical®, Roche) or placebo. Methods: TNF-alpha, IL-6, and 8-epi PGF2alp

The genus Helicobacter has expanded at a rapid pace and no fewer than 31 species have been named since the proposal of the genus in 1989. Of these 31 species, 22 are principally associated with extragastric niches and there is increasing interest in the role of these taxa in diseases of humans and animals. Substantial evidence attests to certain species playing a role in the pathogenesis of enteri

The compacting behavior of agglomerated aerosol nanoparticles in the size range between 7 and 150 nm was investigated using available literature data. We observed a characteristic behavior, which can be described by three separate steps. When comparing the first step, the compaction from agglomerates into spherules, differences could be observed for nanoparticles of different materials. It is seen

A laboratory procedure is described for measuring methane potentials of organic solid waste. Triplicate reactors with 10 grams of volatile solids were incubated at 55 degreesC with 400 ml of inoculum from a thermophilic biogas plant and the methane production was followed over a 50-day period by regular measurements of methane on a gas chromatograph. The procedure involves blanks as well as cellul

Pressurized Liquid Extraction was utilized for the extraction of seven selected polychlorinated biphenyls (28, 52, 101, 118, 153, and 180) from a naturally contaminated fishmeal and two feed samples fortified with a naturally contaminated fish oil sample. In order to assure sufficient extraction efficiencies, the extraction solvent, the extraction temperature, and the flush volume were optimised b

Department of Occupational and Environmental Medicine, Institute of Laboratory Medicine, Lund University Hospital, S-221 85 Lund, Sweden. The aim of this study was to investigate if the uptake of N-methyl-2-pyrrolidone (NMP), a widely used industrial chemical, increases after exposure to NMP in humid air compared to dry air. NMP has been described to be an airway irritant and a developmentally to

Studies of language in children with mild-to-moderate hearing impairment ( HI) indicate that they often have problems in phonological shortterm memory (PSTM) and that they have linguistic weaknesses both in vocabulary and morphosyntax similar to children with specific language impairment (SLI). However, children with HI may be more likely than children with SLI to acquire typical language skills a

This paper approaches the uncertainty problem from the point of view of adaptive control. The uncertainty is reduced by continuous monitoring of the response of the system to the control actions and appropriate modifications of the control law. It is shown that this approach makes it possible to deal with uncertainties that cannot be handled by high gain robust feedback control.

Popular Abstract in Swedish Torgny Lindgren är en av våra mest framstående diktare. Han har som få kunnat förena berättarglädje, språklig skönhet, och djupsinne på ett sätt som har lockat läsare ur alla kretsar. Lindgrens berättelser är emellertid på ett gåtfullt sätt ofta både brutala och djupt allvarliga, samtidigt som de är både vackra och komiska. Ofta går också döden hand i hand med en kärlekThis thesis addresses the work of the Swedish author, Torgny Lindgren (born 1938). Its main focus lies on the all-pervading irony in his work. The use of irony is seen as a unifying trait in Lindgren’s authorship. The development of more complex ironies during the years of his authorship is seen as an effect of his authorship’s thematic development, moving from political satire to existential, eth

This paper presents a post processing strategy for myocardial velocity fields obtained by phase contrast magnetic resonance imaging. Such data can be used to track cardiac motion and to calculate strain. The method combines data regularization with optical flow estimation to overcome the partial volume effect in the image acquisition. Validation is performed both in vitro and in vivo and it is sho

Planar gamma-scintigraphy is often used to quantify pulmonary deposition patterns from aerosol inhalers. The results are quite different from those obtained using 3-dimensional PET and SPECT. The purpose of this study was to characterize the effects of scatter and tissue attenuation on the distribution of radiolabeled aerosol as measured by planar scintigraphy using Monte Carlo simulations. This s
