Background: L1 is an important primary rRNA-binding protein, as well as a translational repressor that binds mRNA. It was shown that L1 proteins from some bacteria and archaea are functionally interchangeable within the ribosome and in the repression of translation. The crystal structure of bacterial L1 from Thermus thermophilus (TthL1) has previously been determined. Results: We report here the

A combined paleomagnetic and Ar-40/Ar-39 study was carried out along eight stratigraphically overlapping sections in the Oligocene Afro-Arabian flood volcanic province in Yemen (73 sites). The composite section covers the entire volcanic stratigraphy in the sampling region and represents five polarity zones that are correlated to the geomagnetic polarity time scale based on Ar-40/Ar-39 ages from t

Three fermented, ropy, non-dairy, oat-based products were evaluated for their effect on serum lipids, faecal cholesterol and faecal short chain fatty. acids in germfree and conventional rats. Three different exopolysaccharide (EPS) producing lactic acid bacteria strains were used to ferment the non-dairy oat-base (Adavena(R) G40) (Ceba Foods AB, Lund; Sweden). Two commercial non-dairy products bas

BACKGROUND The ability to self-assess one's competence is a crucial skill for all health professionals. The interactive examination is an assessment model aiming to evaluate not only students' clinical skills and competence, but also their ability to self-assess their proficiency. METHODS The methodology utilised students' own self-assessment, an answer to a written essay question and a group disc

Triptans are agonists at 5-HT1B and 5-HT1D (where 5-HT is 5-hydroxytryptamine; serotonin) receptors and cause vasoconstriction of isolated blood vessels. The aim of the present study was to determine vasoconstrictor potency (EC50) of triptans in human coronary and cerebral arteries and to examine whether there was any relationship with the maximal plasma concentrations (Cmax; nM) of the drugs achi

A biologically active protein fraction was isolated from rabbit intestine, purified by one-dimensional SDS-PAGE and stained with Coomassie Brilliant Blue. A predominant band of approximately 110-130 kDa was excised and digested in-gel with trypsin. The resulting peptides were extracted then separated by microbore reversed-phase high-performance liquid chromatography (HPLC). Mass spectrometric data

In this paper we present some results on model based force estimationand how these estimates can be integrated in a common robot force controlscheme. A generalization of the force estimation method proposed inHacksel and Salcudean (1994) is done and a force observerable to follow ramp environmental forces is introduced. Anextension of this method for robotic manipulators is also experimentallyveri

Abstract: Under 2012/2013 genomfördes projektet OER-öppna möjligheter för lärande www.oersverige.se, finansierat av .SE (Stiftelsen för Internetinfrastruktur). Projektet koordinerades av Karlstad universitet. Sammantaget deltog nio lärosäten i Sverige. Syfte: Ett av syftena var att generellt främja medvetenheten i frågor om OER (Open Educational Practice), öppna delningskulturer och praxis. För

The semi-arid Amboseli landscape, southern Kenya, is characterised by intermittent groundwater-fed wetlands that form sedimentary geoarchives recording past ecosystem changes. We present a 5000-year environmental history of a radiocarbon dated sediment core from Esambu Swamp adjacent to Amboseli National Park. Although radiocarbon dates suggest an unconformity or sedimentary gap that spans between

Pulmonary artery grafts are needed as cardiovascular bioprosthetics. For successful tissue recellularization after transplantation, lipids have to be removed from the donor artery. Developing a selective process to remove lipids without damaging the extracellular matrix greatly depends on knowing the amount and type of lipid compounds in the specific tissue. Here we present an efficient methodolog

Coherent folded acoustic phonons in a multilayered GaSb/InAs epitaxial heterostructure were generated by femtosecond laser pulses and studied by means of ultrafast x-ray diffraction. Coherent phonons excited simultaneously in the fundamental acoustic branch and the first back-folded branch were detected. This represents the first clear evidence for phonon branch folding based directly on the atomi

Ny rättspraxis från EG-domstolen i fallen Köbler och Kühne & Heitz har visat att domstolen är beredd att etablera rättsprinciper som kommer göra det möjligt att på ett effektivt sätt hantera missbruket av acte clair-doktrinen. I det förstnämnda fallet, etablerade domstolen en möjlighet att utkräva skadeståndsansvar av medlemsstaten i det fall den nationella sista instansrätten (in casu den hög

Using a grounded theory perspective, this article focuses on experiences of participation in relation to home among very old people who are living alone. Eight people selected from the larger ENABLE-AGE Project were interviewed. Data analysis identified the core category as "home as the locus and origin for participation" with two main categories ("performance-oriented participation" and "together

Mechanical interlock obtained by penetration of bone cement into cancellous bone is critical to the success of cemented total hip replacement (THR). Although acetabular component loosening is an important mode of THR failure, the properties of acetabular cancellous bone relevant to cement penetration are not well characterized. Bone biopsies (9 mm diameter, 10 mm long) were taken from the articula

Popular Abstract in Swedish Av de industrier som kom att spela en viktig roll för den starka ekonomiska utvecklingen i Sverige från 1890-talet och framåt befann sig den moderna verkstadsindustrin i frontlinjen. Syftet med denna avhandling är att diskutera hur de teknologiska förändringar som präglade den andra industriella revolutionens inledande fas påverkade den relativa efterfrågan på yrkesskicSweden experienced a remarkable economic growth in the period 1890-1930, to a large extent due to a very successful adaptation of core elements of the Second Industrial Revolution such as electricity and mechanical engineering. Theoretically this thesis aims at discussing changes in the balance between the relative demand for skilled and unskilled labour during the first phase of the Second Indust

The mechanisms behind the long duration of bronchodilating action of the beta 2-adrenoceptor agonists formoterol and salmeterol are only partially understood. This review compares pharmacological characteristics of long-acting versus short-acting beta 2-adrenoceptor agonists in human and animal airways. Based upon the reviewed evidence, it is concluded that for beta 2-adrenoceptor agonists, long d
