1. 1. Neural Interfaces to the Odour World of Scarab Beetles

   Författare :Mattias Larsson; Biologiska institutionen; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Biophysical chemistry of the ALS-associated protein SOD1 : Implications for folding, aggregation and in-cell behaviour

   Författare :Fan Yang; Mikael Oliveberg; Per Jemth; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SOD1 ALS folding in-cell NMR aggregation; Biochemistry; biokemi;

   Sammanfattning : Biophysical chemistry deals with the structural behavior, properties and molecular function of biological macromolecules. A long-standing challenge is here to establish how these macromolecular features change upon transfer from simplified conditions in vitro to the crowded and molecularly complex environment of live cells.

4. 3. Olfaction in Desert Locusts- Anatomy, Function and Plasticity of the Central Olfactory System

   Författare :Rickard Ignell; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hist; serotonin; immunocytochemistry; juvenile hormone; development; olfactometer; intracellular recording; evolution; projection neuron; receptor neuron; antennal lobe; aggregation pheromone; neuroethology; olfaction; Desert locust; Schistocerca gregaria; Ecology; Ekologi; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

   Sammanfattning : The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. LÄS MER

5. 4. Learning and memory in moths - plasticity in behaviour and neurophysiology

   Författare :Ruey-Jane Fan; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proboscis extension reflex PER ; LTM; MTM; STM; memory; inter-trial-interval ITI ; inter-stimulus interval ISI ; US; CS; olfaction; Associative learning; classical conditioning; discrimination; the US pathway; Ecology; Ekologi; Animal physiology; Djurfysiologi;

   Sammanfattning : The moth, Spodoptera littoralis, was demonstrated to be a new model system for studying mechanisms underlying odour conditioning. In the experiments a restrained moth was trained to learn an association between a conditioned stimulus (CS) and an unconditioned stimulus (US). LÄS MER

7. 5. Cell responses in infected and cystic fibrosis respiratory epithelium

   Författare :Rashida Hussain; Godfried M . Roomans; Maria Björkqvist; Ferenc Karpati; Hans Kollberg; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; airway epithelial cells; cystic fibrosis; bacterial infection; CFTR; ENaC; chloride transport; intracellular calcium; P. aeruginosa internalization; Biomedicin; Biomedicine;

   Sammanfattning : Respiratory Epithelium. Örebro Studies in Medicine 99. Cystic fibrosis (CF) is caused by a mutation in a cAMP-activated chloride (Cl-) channel (CFTR). Mortality and morbidity in CF is mainly due to the deregulated responses of the airway epithelial cells. LÄS MER
