Two cases of Wegener's granulomatosis with unusual localization of granulomatous vasculitis
Kinetics and mechanism for platination of thione-containing nucleotides and oligonucleotides: evaluation of the salt dependence
Reactions of cis-[PtCl(NH3)(CyNH2)(OH2)](+) (Cy = cyclohexyl) with thione-containing single-stranded oligonucleotides d(T8XT8) and d(XT16) (X = I-s6 or U-s4) and the mononucleotides 4-thiouridine ((UMP)-U-s4) and 6-mercaptoinosine ((IMP)-I-s6) have been studied in aqueous solution at pH 4.1. The reaction kinetics was followed using HPLC methodology as a function of ionic strength in the interval 5
Atopy patch test reactions to Malassezia allergens differentiate subgroups of atopic dermatitis patients.
Background The yeast Malassezia is considered to be one of the factors that can contribute to atopic dermatitis (AD). Objectives To investigate the reactivity to Malassezia allergens, measured as specific serum IgE, positive skin prick test and positive atopy patch test (APT), in adult patients with AD. Methods In total, 132 adult patients with AD, 14 with seborrhoeic dermatitis (SD) and 33 heal
The autoimmune regulator protein has transcriptional transactivating properties and interacts with the common coactivator CREB-binding protein
Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy, caused by mutations in the autoimmune regulator (AIRE) gene, is an autosomal recessive autoimmune disease characterized by the breakdown of tolerance to organ-specific antigens. The 545 amino acid protein encoded by AIRE contains several structural motifs suggestive of a transcriptional regulator and bears similarity to cellular prote
The Reflector: a new method for saving anaesthetic vapours
Anaesthesia systems that minimize the use of volatile anaesthetics to reduce cost and pollution are of interest. Closed circuit anaesthesia is the ideal solution, but requires continuous adjustment of fresh gas flow and composition and thus is demanding in routine practice. We describe an alternative system, the Reflector system, which is open in regard to oxygen, nitrogen and N2O, and semiclosed
Growth and morphology of mesoporous SBA-15 particles
Transport of diluted volatile organic compounds through pervaporation membranes
Over the years, pervaporation has been widely investigated as a technique for separation of liquid mixtures and recovery of organic compounds from diluted solutions. So far, the research has focused on applications in wastewater treatment, in pharmaceutical industry, for removing the products from fermentation broth in bioreactors and for aroma recovery. When it comes to pervaporation of aroma com
Isolation and initial characterization of a novel zinc finger gene, DNMT3L, on 21q22.3, related to the cytosine-5-methyltransferase 3 gene family
We have isolated the DNMT3L gene that is related to the cytosine-5-methyltransferase 3 (DNMT3) family. The gene is located on chromosome 21q22.3 between the AIRE and the KIAA0653 genes and spans approximately 16 kb of genomic sequence. The encoded protein of 387 amino acids has a cysteine-rich region containing a novel-type zinc finger domain that is conserved in DNMT3A and DNMT3B but also in ATRX

On the use of Titration Calorimetry to Study the Association of Surfactants in Aqueous Solutions
Isothermal titration calorimetry is increasingly becoming a common tool for the investigation of surfactant association processes. This can be associated with the development of new, sensitive and easy-to-operate commercial equipment, allied with the advantage of producing simultaneous information on the main thermodynamic parameters associated with the process under investigation. However, a sign
Evolution of pistil length as a choice mechanism for pollen quality
During the fertilisation process in plants, pollen tube growth rate may be selected as a trait important in male to male competition. Since female morphology provides the necessary selective arena for such competition. we investigate if sexual selection theory can be used to explain the evolution of pistil length as a female choice mechanism. This choice is performed by direct interference with ma
Optimisation of membrane area and energy requirement in tubular membrane modules
During ultrafiltration (UF), the driving force along the membrane is diminished due to concentration increase and frictional pressure drop. In most applications of ultrafiltration the influence of the frictional pressure drop is negligible. However, when treating concentrated, viscous liquids the frictional pressure drop can reduce the transmembrane pressure (TMP) significantly. The influence of c
The effect of dominance rank on fat deposition and food hoarding in the Willow Tit Parus montanus - an experimental test
We studied the effects of dominance rank on fat deposition and hoarding behaviour in Willow Tits Parus montanus . Dominant individuals can displace subordinates which gives them priority to new food sources; they can also pilfer stored food from subordinates. This gives subordinates less certain access than dominants both to their own caches and to new food sources. Theory predicts that subordinat
Industrial implementation of on-line performance monitoring tools
This paper treats implementation of on-line procedures forautomatic performance monitoring. Two on-line detectionprocedures, one that detects oscillations in control loopsand one that detects sluggish control loops, are first summarized.The implementation aspects of these procedures are then discussedand experiences of their use in various industrial products aredemonstrated.
Monitor – Biology
An insight into the latest developments in drug discovery through brief synopses of recent publications, summarizing the chemistry, pharmacological significance and biological relevance of new molecules.
A novel method for mixture viscosity control based on change detection
The paper presents a novel method for detecting abrupt changes in mixture viscosities. This problem arises in numerous industrial applications and different solutions are suggested in the literature. An approach of using non-linear filtering for detection-an adaptive filter combined with a change detector-is outlined in this paper. As a case study, we present an ash stabilization batch mixing proc
Increased rates of psychosis among immigrants to Sweden: is migration a risk factor for psychosis?
Background. Previous studies have shown high rates of psychosis among Afro-Caribbean immigrants to the UK and immigrants to the Netherlands. Rates of schizophrenia-like psychoses (SLP), i.e. schizophrenia or other non-affective psychosis, among the native-born and immigrant populations were assessed in Malm, the city in Sweden with the highest proportion of immigrants.Methods. All adult patients a
A comparison of the rheological properties of wheat flour dough and its gluten prepared by ultracentrifugation
Ultracentrifugation has been used as a tool for separating dough into different phases and as dough can be described as a bicontinuous system, gluten forms one phase, and starch another. The aim of this study is to investigate the possibility of using ultracentrifugation to extract gluten from dough. By using this method disadvantages such as excess washing, drying and reconstitution of dried glut
Carpal tunnel syndrome in repetitive work: A follow-up study
Background The Project on Research and Intervention in Monotonous work (PRIM) studied Danish workers for 3-4years to determine the effects of monotonous work. The present study is a subset of that cohort and compares prevalence and incidence differences of carpal tunnel syndrome (CTS) between workers with highly repetitive work tasks and workers with varied work tasks. Methods The baseline study i
