  2. 1. Studies on Cytotoxic and Neutrophil Challenging Polypeptides and Cardiac Glycosides of Plant Origin

    Author : Senia Johansson; Tore Mellstrand; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; cytotoxic; neutrophil; polypeptides; Phoradendron tomentosum; Digitalis purpurea; plant; mistletoe; MS MS; Edman degradation; breast cancer; macrocyclic peptides; multidrug resistance protein; primary structures; phoratoxin; isolation; digitoxin; cardiac lycoside; structure-activity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; farmakognosi;

    Abstract : This thesis examines the isolation and characterisation (biological and chemical) of polypeptides from plants. A fractionation protocol was developed and applied on 100 plant materials with the aim of isolating highly purified polypeptide fractions from small amounts of plant materials. READ MORE

  5. 3. Aquaporin homologues in Norway spruce (Picea abies)

    Author : Peter Oliviusson; David I. Dunstan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : The recent discovery of aquaporins - proteins that mediate bidirectional passage of water over membranes - provides a molecular basis for the underlying processes in plant water relations. In plants, aquaporins are found in plasma membranes and in vacuolar membranes (tonoplasts) and are suggested to participate in dynamic operations such as cell elongation, osmotic regulation, and long-distance transport.

  6. 4. Neural Interfaces to the Odour World of Scarab Beetles

    Author : Mattias Larsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Intra; Antennal lobe; CNS; Attraction; Olfactometer; Behaviour; Mass spectrometry; Gas chromatography; Electrophysiology; Single sensillum; Receptor neuron; Plant volatile; Sex pheromone; Neuroethology; Odour detection; Olfaction; Coleoptera; Scarabaeidae; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Abstract : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species. Electrophysiological single cell recordings in A. READ MORE

  7. 5. Plant-Derived Substances and Cardiovascular Diseases : Effects of Flavonoids, Terpenes and Sterols on Angiotensin-Converting Enzyme and Nitric Oxide

    Author : Ingrid Persson; Rolf G.G. Andersson; Lars Bohlin; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Diet has for many years been known to play a key role in the development of chronic diseases. There are clear associations between consumption of vegetables, fruits and berries, and risk of cardiovascular diseases, the number one cause of death in the world. READ MORE
