  1. 1. Identification and characterisation of chitin and cellulose synthases in oomycetes : New tools for biochemical studies and structure determination

    Författare :Stefan Klinter; Vincent Bulone; Lauren S. McKee; Mirjam Czjzek; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biochemical characterisation; cellulose synthase; chitin synthase; in vitro activity assay; microtubule-interacting and trafficking domain; nanoparticle; oomycetes; phylogenetic analysis; yeast engineering; biokemisk karakterisering; cellulosasyntas; kitinsyntas; in vitro aktivitetsanalys; mikrotubulus-interagerande och -trafikerande domän; nanopartikel; oomyceter; fylogenetisk analys; jäst proteinteknik; Bioteknologi; Biotechnology;

    Sammanfattning : Despite resembling ‘true’ fungi in terms of morphological features, oo­mycetes form a distinct eukaryotic lineage of filamentous microorganisms that belongs to the stramenopiles, a group of protists also comprising the closely-related brown algae and diatoms. Many oomycetes are devastating pathogens of plants and animals, globally causing significant economic los­ses in the agriculture and aquaculture industries, and posing considerable environmental damage to natural ecosystems.

  3. 2. Characterisation of CtBP : A Co-Repressor of Transcription that Interacts with the Adenovirus E1A Protein

    Författare :Anders Sundqvist; Anthony Wright; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; CtBP; HDAC; adenovirus; E1A; gene expression; repression; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : In this study, adenovirus E1A has been used to target and analyse the transcriptional function of the cellular C-terminal Binding Protein (CtBP).Transcription is a complex biochemical process that represents a major regulatory step in gene expression. LÄS MER

  4. 3. Biochemical characterisation of landfill leachate toxicity in fish

    Författare :Maria Linderoth; Lennart Balk; Ulf Rannug; Cinta Porte Visa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landfill leachate; endocrine disruption; fish; Environmental toxicology; Miljötoxikologi;

    Sammanfattning : Deposition remains the most common form of waste disposal in many parts of the world. As a terminus of the products consumed in our society a landfill may contain virtually all sorts of man-made chemicals. Despite this, the harmfulness of landfill leachate has not been extensively evaluated in feral organisms in the environment. LÄS MER

  5. 4. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods

    Författare :Charlotta Löfström; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; mykologi; virologi; bakteriologi; Mikrobiologi; validation; Microbiology; bacteriology; virology; mycology; Salmonella; ribotyping; detection; animal feed; randomly amplified polymorphic DNA; pulsed-field gel electrophorsis; pre-PCR processing; PCR; polymerase chain reaction; genotyping;

    Sammanfattning : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

  7. 5. Biochemical characterisation and clinical correlation of neuropeptides in neuroblastoma with emphasis on neuropeptide Y

    Författare :Per Bjellerup; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :chromatography; CPON; ganglioneuroma; mass spectrometry; neuroblastoma; neuropeptide Y; pancreastatin; phaeochromocytoma; primary structure; radioimmunoassay; somatostatin; vasoactive intestinal peptide;

    Sammanfattning : Neuropeptides influence cellular events involved in tumour growth and differentiation. Neuroblastoma, a malignant childhood tumour of neural crest origin, synthesises and releases monoamines and neuropeptides. The concentrations of some of these neuropeptides in plasma are correlated to clinical stage and outcome. LÄS MER
