The aims of this study were: (i) to assess the test-retest intrarater reliability of eccentric ankle dorsiflexor muscle performance in young healthy men and women using the Biodex dynamometer; and (ii) to examine different statistical indices for the interpretation of reliability. Thirty men and women (age 22.5 +/- 2.5 years, mean +/- S.D.) performed three maximal eccentric contractions at 30 degr

Popular Abstract in Swedish Inför hjärtkirurgi är bedömning av en patients individuella nytta av och risk vid en hjärtoperation en viktig komponent i utredningen inför operationen. En riskstratifiering innebär att patientens olika riskfaktorer (exempelvis sockersjuka, högt blodtryck, antal tidigare hjärtinfarkter, hjärtfunktion) vägs samman till en sannolikhets-bedömning av risken för en viss händThe aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural net

A fission fragment accelerator combined with the Munich high-flux reactor FRM-II is under design for the delivery of intense beams of mass separated very neutron-rich fission fragments with energies at the Coulomb barrier They can be used to produce very heavy neutron-rich nuclei in fusion reactions. The large neutron excess will result in much longer lifetimes of the produced heavy elements, comp

Popular Abstract in Swedish Hörselskadade elever i Jordanien - en studie av faktorer som påverkar elevernas skol- och fritidsaktiviteter. Det övergripande syftet med studien är att beskriva och analysera faktorer som påverkar hörselskadade elevers skol- och fritidsaktiviteter. För att uppnå syftet konstruerades enkäter som distribuerades till hörselskadade elever, deras lärare och föräldrar. FakThe main aim of this study is to describe and analyse the factors affecting the daily life activities of hearing-impaired students in Jordan from the point of view of hearing-impaired students, their teachers, and their parents. Two questionnaires were developed, one directed towards the activities, and the other to the factors affecting these activities. The two questionnaires were distributed am

Cells from the human teratocarcinoma line NTera-2 can be induced to terminally differentiate into postmitotic neurons when treated with retinoic acid. However, this differentiation process is rather time consuming as it takes between 42 and 54 days. Here, we propose a modified differentiation protocol which reduces the time needed for differentiation considerably without compromising the quantity

We discuss the stochastic dynamics of biological (and other) populations presenting a limit behaviour for large environments (called deterministic limit) and its relation with the dynamics in the limit. The discussion is circumscribed to linearly stable fixed points of the deterministic dynamics, and it is shown that the cases of extinction and non-extinction equilibriums present different feature

This work presents an integrated analytical system based on immobilized engineered microorganisms and bioluminescence measurements for monitoring of bioavailable heavy metal ions (Cu being chosen as a model ion). A strain of microorganisms from Alcaligenes eutrophus (AE1239) was genetically engineered by inserting a luxCDABE operon from Vibrio fischeri under the control of a copper-induced promote

A rapid and sensitive novel type of bioelectronic Region Ion Sensitive Field Effect Transistor (RISFET) nanosensor was constructed on a chip with a 65 nm sensing electrode gap. The RISFET nanosensor was demonstrated for the environmental pesticide analysis of neurotoxic organocarbamate/carbofuran. The linear range for carbofuran analysis is ac signal frequency dependent, studied in the range (500

Z-Ligustilide, a naturally occurring phthalide isolated from Ligusticum porteri, underwent Diels-Alder reactions with different dienophiles yielding novel tricyclic products with potentially interesting biological properties. Where selectivity was possible, the reactions performed showed regio- and stereoselectivity. The experimental results with ethyl acrylate were compared with the selectivity p

Artikeln behandlar muralmålningarna i Borgmästarehuset i Ystad, som 1907 demonterades och flyttades till museiområdet i staden. De kan av förfataren med hjälp av fotografisk dokumentation beläggas på samma plats före rivningen, och de dateras med hjälp av träsnitt som kan ha fungerat som förlagor till 1500-talets senare del. Deras ikonografi, kring Kristi passionshistoria, och deras funktion i en

The adaptation of three allopatric populations of a generalist moth, Operophtera brumata (L.), on two tree species, Prunus padus (L.) and Quercus robur (L.) which represent the extremes of the timing of budburst in spring, was studied in Finland and Sweden. The synchrony of the hatching and budbursting was monitored, and its importance to dispersal and growth of larvae was assessed by rearing coho

1. The combination of interleukin-2 (IL-2) and IL-4 reduces the inhibitory effects of glucocorticoids on granulocyte-macrophage colony-stimulating factor (GM-CSF) production, in agreement with the hypothesis that this combination causes glucocorticoid resistance. Whether a general cytokine resistance to glucocorticoids is induced by IL-2 and IL-4 has not been reported. 2. Mononuclear blood cells f

Silicone tubes of appropriate sizes were used to enclose the injured zone of transsected ulnar and median nerves in the human forearm as an alternative to conventional microsurgical repair of the nerve trunk. A gap measuring 3-5 mm was left intentionally between the nerve ends inside the tube. The clinical early results from a prospective randomised study that compared these two principles have re
