We study how the orientational correlations of DNA confined to nanochannels depend on the channel diameter D by means of Monte Carlo simulations and a mean-field theory. This theory describes DNA conformations in the experimentally relevant regime where the Flory-de Gennes theory does not apply. We show how local correlations determine the dependence of the end-to-end distance of the DNA molecule
In an attempt to gain information about the identity of the Golgi apparatus casein kinase(s) (G-CK), responsible for the phosphorylation of caseins in lactating mammary gland, the proteins present in fractions enriched in G-CK activity eluted from DEAE-Sepharose and heparin-Sepharose columns were resolved by two-dimensional electrophoresis and analyzed by mass spectrometry. This led to the identif
We tested the hypothesis that early brain recovery in hypoxic newborn piglets is improved by resuscitating with an O2 supply close to the minimum level required by the newborn piglet brain. Severely hypoxic 2-5-d-old anaesthetized piglets were randomly divided into three resuscitation groups: hypoxaemic (n = 8), 21% O2 (n = 8), and 100% O2 groups (n = 8). The hypoxaemic group was mechanically vent
Aim: A correct diagnosis of coeliac disease, one of the most common chronic diseases in Swedish children, demands small bowel biopsy, which can be performed endoscopically or by means of a peroral capsule. Recently there was a debate among Swedish paediatric gastroenterologists, with some advocating the cessation of capsule biopsy in favour of endoscopic biopsies. To gain information on which to b
Several studies show that there are interactive processes between eutrophication and uptake of persistent organic pollutants (POPs) in aquatic biota. The main concept is that the increased biomass and production in aquatic ecosystems, due to excess discharge of nutrients, causes a chain event that results in reduced uptake of POPs in primary producers (phytoplankton). This effect is then transferr
The aims of the current study were to collect intestinal spirochaetes (genus Brachyspira) from farmed and wild mallards (Anas platyrhynchos) and to identify and classify those isolates that phenotypically resembled Brachyspira hyodysenteriae, an enteric pathogen of pigs. The isolation rate of Brachyspira spp. was high from both farmed (93%) and wild mallards (78%). In wild mallards, it appeared th
We report a case of a large, deep-seated, diagnostically difficult angiomatoid fibrous histiocytoma. The neoplastic cells were positive for vimentin, calponin, CD99, and, focally, for desmin and contained intertwining cytoplasmic processes joined by desmosomelike junctions. Fusion of codon 175 of the FUS gene to codon 110 of the ATF1 gene was detected by reverse transcription-polymerase chain reac
A search for the simultaneous presence of two hepatitis C virus (HCV) types in sera of a group of chronically infected intravenous drug users, hemodialysis patients and hemophiliacs from Sweden and Russia was performed with two genotyping methods based on the use of type-specific primers from core and NS4 regions of the viral genome. An important feature of NS4 based assay is that type-specific pr
Various methods for deriving atomic partial charges from the quantum chemical electrostatic potential and moments have been tested for the sucrose molecule. We show that if no further information is used, the charges on some carbon atoms become large and charge patterns involving these atoms are badly determined and poorly transferable. Adding lone-pairs on the ether oxygen atoms or dividing the m
Antimicrobial resistance patterns and capsular groups of penicillin-resistant Streptococcus pneumoniae (PRP; MIC penicillin G >= 0.5 mg/ml) in Sweden between 1997 and 2003 were described, and trends in resistance and antibiotic sales during the same period were compared. The most common serogroups were in descending order 9, 19, 14, 23, and 6. Despite a low and stable annual PRP rate (proportion o
Popular Abstract in Swedish Förtroende och nationella perspektiv i multinationell krishantering: en studie av Europeiska Unionens militärstrategiska nivå Doktorsavhandling av Olof Ekman, avdelningen för Brandteknik och Riskhantering vid Lunds Tekniska Högskola (LTH), Lunds Universitet, försvarad den 9 december 2011. Tidigare forskning pekar på att förtroende i större kriser är viktigt för att saThis thesis is motivated by an increasing degree of unfamiliarity and prominence of national dimensions in multinational crisis management. The research rationale rests on the argument that trust is important but may erode when roles conflict, which in turn may result when stakeholder interests diverge. The thesis describes trust and national perspectives in terms of role conflict in an EU Operati
Introduction. Radioiodine and most cytostatic treatments are contraindicated in pregnancy. Still, inadvertent therapy does occur. Radioiodine was given to two pregnant women with Graves' disease and thyroid cancer respectively, both in their 20th gestational week. Routine pregnancy tests based on urinary β-hCG had failed to indicate pregnancy in both cases. Methods. Estimation of doses to the foet
OBJECTIVES: To study long-term patient-relevant outcomes after meniscectomy, a surgical procedure associated with a high risk of knee osteoarthritis (OA). Principal objectives were to compare traumatic with degenerative meniscal tear and partial with subtotal meniscectomy.METHODS: We studied a well-defined cohort of 205 patients who had undergone isolated unilateral meniscectomy between 1983 and 1
The mechanical integrity of tin-doped indium oxide (ITO) thin films sputtered onto a high temperature aromatic polyester developed for flexible display applications was investigated by means of tensile experiments equipped with electrical measurement, and carried out in-situ in an optical microscope. Attention was paid to the influence of ITO thickness, composition and crystalline microstructure,
This study was undertaken to determine the value of stained smears from the vaginal introitus and the posterior vaginal fornix for detection of candida morphotypes in the diagnosis of recurrent vulvovaginal candidosis (RVVC) in cases with an assumed novel attack of the condition, and to compare the value of microscopy of such smears in relation to candida culture, vaginal pH-determinations and leu
1 We examined non-adrenergic, non-cholinergic (NANC) stimulation for its stabilizing effect on bronchial smooth-muscle tone with respect to its regulatory power and the effect of variations in neural impulse frequency. 2 The guinea-pig isolated main bronchus (n = 4-12) was pretreated with indomethacin (1O JAM) and incubated with atropine (1 pM) and guanethidine (10 JM). Electrical field stimulatio
New radiative lifetimes for 20 levels of Pr II have been measured using the time-resolved laser-induced fluorescence (LIF) technique. The combination of these experimental values with theoretical branching fractions (BF) obtained with the pseudo-relativistic Hartree-Fock (HFR) approach has allowed us to determine oscillator strengths and transition probabilities for about 150 lines appearing in th
It is well known that for a robotic manipulator without sensors on the end-effector, the end-effector has to follow a path in its workspace without regard to any feedback other than its joints shaft encoder or resolvers. This fact imposes severe limitations on certain tasks where an interaction between the robot and the environment is needed. However, with the help of sensors, a robot can exhibit
