  2. 1. Odour detection in the desert locust, Schistocerca gregaria: antennal structure and function

    Author : Samuel Adhola Ochieng'; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; insect antennae; Olfaction; chemoreceptors; receptor neuron; electrophysiology; aggregation pheromone; SEM; TEM; Djurfysiologi; Animal physiology; Animal ethology and psychology; Djurs etologi och psykologi;

    Abstract : The desert locust, Schistocerca gregaria, is a polymorphic insect that occurs in two morphological and physiological distinct phases, solitary and gregarious, depending on population density. The two phases are reversible at any developmental stage. The gregarious phase produces and uses stage-specific pheromones, that keep the swarm together. READ MORE

  4. 2. Smells of sociality : insect chemoreceptors, sex and habitat cues

    Author : Francisco Gonzalez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The last two decades have seen considerable research effort dedicated to understanding the molecular basis of insect olfaction. There are, however, many knowledge gaps, especially when it comes to how insects detect different olfactory stimuli from the environment. READ MORE

  5. 3. 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

  6. 4. On the interaction between a neuromuscular blocking agent and regulation of breathing during hypoxia

    Author : Nicholas Wyon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neuromuscular block; TOF ratio; vecuronium; ventilatory response; chemoreceptors; carotid body;

    Abstract : It was previously generally agreed that a mechanical train-of-four (TOF) ratio >0.70 represented an adequate recovery of respiratory function after neuromuscular blockade. Normal respiratory parameters at this level of recovery and during air breathing support this view. READ MORE

  7. 5. Nicotinic transmission and drugs in anesthesia : neuromuscular blocking agents and propofol : consequences for carotid body function

    Author : Malin Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Carotid body; chemoreceptors; neuromuscular blocking agents; propofol; acetylcholine; nicotinic acetylcholine receptors;

    Abstract : The carotid body is the global oxygen sensor of the human body. Acute hypoxia elicits instant hyperventilation mediated from the carotid body type 1 cells, where nicotinic transmission is a key component in oxygen sensing and signalling. READ MORE
