  2. 1. Specific language impairment: Neurophysiological studies of children and their parents

    Author : Marianne Ors; Klinisk neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SPECT; neuropsykologi; neurofysiologi; N400; P300; P3; N1; ERPs; event-related brain potentials; children; developmental language delay; Specific language impairment; language disorder; Neurology; neuropsychology; neurophysiology; Neurologi;

    Abstract : Specific language impairment (SLI) is commonly described as a condition where a child with otherwise normal development and hearing does not acquire language as expected. Children with SLI often have a family history of language disorders. The aetiology is poorly understood. READ MORE

  4. 2. Olfactory genomics of bark- and ambrosia beetles : Evolution and function of chemoreceptors

    Author : Twinkle Biswas; Feromongruppen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Curculionidae; functional characterisation; odorant receptors ORs ; gustatory receptors; ionotropic receptors; orthologues; paralogues; olfactory sensory neurons; OR-ligand interaction;

    Abstract : Insect behaviours, such as host and mate selection, are often mediated by chemical cues. The chemical cuesare detected by large and rapidly evolving families of chemoreceptors which include odorant receptors (ORs),gustatory receptors (GRs) and ionotropic receptors (IRs). READ MORE

  5. 3. Observations of young core collapse supernova remnants

    Author : Anestis Tziamtzis; Lundqvist Peter; Sergey Zharikov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernova remnants; Crab; SN 1987A; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.

  6. 4. From sequence to function : Comparative studies of insect olfactory receptors

    Author : Xiaoqing Hou; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Olfactory receptor; Heterologous expression; Pheromone; Plant volatile; Insect;

    Abstract : In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. READ MORE

  7. 5. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Author : Jothi Kumar Yuvaraj; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    Abstract : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).
