Two-step steam pretreatment of softwood on laboratory scale has previously been shown to result in higher yields than one-step steam pretreatment. In this study, these results are verified on a larger scale. In an industrial process filtration and washing of the material between the two pretreatment steps are difficult without release of pressure. A worst case without filtration or washing was thu

Gadolinium chelates, intended as intravenous contrast media for magnetic resonance imaging, have been regarded as nonnephrotoxic and recommended to replace iodinated contrast media in patients with azotemia who are undergoing digital subtraction angiography (DSA). High intraarterial doses (up to 220 mmol of gadodiamide) have been used, with a 40% incidence of nephropathy. The authors discourage th

No generally accepted definition of osteoarthritis exists. Traditionally, the diagnosis is obtained by radiographic examination but different definitions are used for different purposes. Since no causal treatment exists, treatment is aiming at reducing symptoms and improving function. The correlation between radiographic features of osteoarthritis and symptoms is poor. Thus, it is recommended that

We showed earlier that over-expression of protein kinase C (PKC) epsilon induces neurite outgrowth. The effect is mediated by a region (PKC epsilon PSC1V3) encompassing the pseudosubstrate, the two C1 domains and part of the V3 region, and is independent of the catalytic activity of the enzyme. In this region, residues immediately N-terminal of the C1b domain are crucial for neurite outgrowth. How

Background and Purpose-A low risk of recurrent stroke and death after lacunar infarction has previously been reported, but follow-up has been limited to less than or equal to5 years. Methods-One hundred eighty patients with pure motor stroke, collected between 1983 and 1986 from a hospital-based stroke registry, were followed up until at least 10 years after the index stroke. Two patients were los

Developing a reliable and quantitative assessment of the potential virulence of a malignancy has been a long-standing goal in clinical cytometry. DNA histogram analysis provides valuable information on the cycling activity of a tumor population through S-phase estimates; it also identifies nondiploid populations, a possible indicator of genetic instability and subsequent predisposition to metastas

Objective: To assess the clinical value of serial single photon-emission computed tomographic (SPECT) measurements after aneurysmal subarachnoid hemorrhage (SAH). Methods: Thirty-two patients were studied prospectively during the first 26 days after SAH with repeated SPELT measurements; clinical examinations, and transcranial Doppler recordings. Time trends were analyzed with a general linear mode

Background: The European Molecular Genetics Quality Network (EMQN) was formed in order to improve external quality assessment for molecular genetic testing in Europe. From 1999 to 2002 it received funding from the European Union under the Standards, Measurement and Testing programme (contract no. SMT4-CT98-7515). Since then, its maintenance has been supported through subscription of the participan

BACKGROUND: Yeast and bacteria elicit arachidonate release in macrophages, leading to the formation of leukotrienes and prostaglandins, important mediators of inflammation. Receptors recognising various microbes have been identified, but the signalling pathways are not entirely understood. Cytosolic phospholipase A2 is a major down-stream target and this enzyme is regulated by both phosphorylation

Rabbits skin folds were placed in plexiglass chambers enabling control of the skin fold temperature during cuff compression (200 mmHg) for 4 hours. In 10 animals the skin folds were kept at 36 degrees C - in another 10 animals the skin fold temperature was lowered to 10 degrees C. To quantitate the skin injury caused by the pressure ischemia a standardized wound was made, and immediately closed, a

Popular Abstract in Swedish Denna undersökning inventerar beståndet av beteckningar för EGENDOM I ALLMÄNHET och för MOBIL och IMMOBIL EGENDOM i de regionala medeltida nordiska lagarna (dvs. de danska och svenska landskapslagarna, de norska lagtingslagarna samt den isländska Grágás). Materialet analyseras språkgeografiskt med avsikten att skapa en relativ termkronologi. En grovanalys visar attféThis study investigates the stock of words for PROPERTY IN GENERAL with the subcategories MOVABLE and IMMOVABLE PROPERTY in the regional medieval Scandinavian laws and makes a linguistic-geographical analysis of these words with the aim of establishing a relative term chronology. A crude analysis shows that fé/fæ for PROPERTY IN GENERAL and land for IMMOVABLE PROPERTY were the oldest
