In the process of making ethanol from lignocellulosic materials, compounds inhibitory to microorganisms are generated during steam pretreatment of the wood. Water-soluble inhibitors and pentoses are liberated and washed from the cellulose structure which is further enzymatically hydrolyzed. To make the process economically feasible, rite pentoses have to be fermented to ethanol. A major drawback w
Summary. The international MRI expert subgroup of the International Prophylaxis Study Group (IPSG) has developed a consensus for magnetic resonance imaging (MRI) scales for assessment of haemophilic arthropathy. A MRI scoring scheme including a 10 step progressive scale and a 20 step additive scale with identical definitions of mutual steps is presented. Using the progressive scale, effusion/haema
Bruton's tyrosine kinase (Btk) is a cytoplasmic protein tyrosine kinase consisting of N-terminal pleck-strin homology (PH) domain followed by Tec homology (TH) domain, Src homology 3 and 2 (SH3 and SH2) domains, and a C-terminal kinase domain. Mutations in the human BTK gene cause the severe immunodeficiency disease X-linked agammaglobulinemia (XLA). The structural and functional basis of several
Flameless combustion is an attractive solution to address existing problems of emissions and stability when operating gas turbine combustors. Theoretical, numerical and experimental approaches were used to study the flameless gas turbine combustor. The emissions and combustion stability were measured and the limits of the flameless regime are discussed. Using experimental techniques and Large Eddy
The purpose of the present study was to investigate the amplifying function of the nucleus accumbens septi region (NAS) in 6-hydroxydopamine (6-OHDA)-induced rotational behaviour by implanting fetal dopamine (DA)-rich mesencephalic cell suspensions unilaterally in the NAS of rats previously subjected to combined mesostriatal (MS) and NAS 6-OHDA lesions. First, all the rats received a unilateral 6-
Eleven human primary rhabdomyosarcomas (RMSs), including all histological variants, were analyzed morphologically, immunohistochemically for intermediate filament proteins and actin isoforms, and by means of Northern blots with probes specific for total actin, alpha-skeletal (SK), alpha-cardiac (CARD), and alpha-smooth muscle actin messenger (m)RNAs. All tumors disclosed ultrastructural evidence o
Samples were prepared for ultrastructural studies of the intact interface between metallic implants and tissue by transmission electron microscopy. The method is based on plastic embedding of implant and tissue and subsequent removal of the bulk metal by electrochemical dissolution (electropolishing), to facilitate preparation of ultrathin sections for transmission electron microscopy. Surface sen
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
In response to infection, epithelia mount an innate immune response that includes the production of antimicrobial peptides. However, the pathways that connect infection and inflammation with the induction of antimicrobial peptides in epithelia are not understood. We analyzed the molecular links between infection and the expression of three antimicrobial peptides of the beta-defensin family, human
Anaerobic biodegradation of fermented spent sulphite liquor, SSL, which is produced during the manufacture of sulphite pulp, was investigated. SSL contains a high concentration of lignin products in addition to hemicellulose and has a very high COD load (173 g COD 1(-1)). Batch experiments with diluted SSL and pretreated SSL indicated a potential of 12-22 1 methane per hire SSL, which corresponds
Specific granule protein of 28 kDa (SGP28), also termed cysteine-rich secretory protein 3 (CRISP-3), is a glycoprotein that belongs to a family of cysteine-rich secretory proteins (CRISPs). SGP28 was originally discovered in human neutrophils, but transcripts are widely distributed in exocrine glands (salivary glands, pancreas, and prostate) and also found at lower levels in epididymis, ovary, thy
The alpha-adrenoceptor-mediated contractile effects of noradrenaline (alpha 1 + alpha 2), phenylephrine (alpha 1) and clonidine (alpha 2) on human saphenous veins were investigated in vivo and in vitro. By infusion (0.3 ml min-1) of the drugs (increasing concentrations in the infused solution) into distended (40 mmHg) saphenous veins in six healthy subjects, local vasoconstriction was induced, mea
We have identified and characterized a human endogenous retrovirus (HERV) gag transcript in the human pre-B cell leukemia line Reh. The transcript was found to be a splice product of a structurally intact HERV element located on chromosome 6q13. Its primer binding site is complementary to phenylalanine (F) tRNA, common for the HERV-F family, but the overall genome sequence is closely related to th
The aim of this double-blind, placebo-controlled, cross-over study was to investigate possible improvement in physical performance at an ambient temperature of -15 degrees C by an inhaled dose of 50 micrograms salmeterol in 8 highly trained nonasthmatic cross-country skiers. FEV1 was measured before, during and after the treadmill exercise protocol, which consisted of a warm-up run, runs of 10 min
This thesis analyzes the politics of growth, the policies that in the Swedish context have enabled and complemented socio-political strategies of redistribution as well as the development of a well organized and rather peaceful labour market. The core of the analysis is a broad overview of Swedish policies of economic growth, from the emergence of the Swedish model in the 1930s up to entering the
