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

    University dissertation from Department of Zoology, Lund University

    Author : Samuel Adhola Ochieng'; [1997]
    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

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

    University dissertation from ; Department of Plant Protection Biology, Swedish University of Agricultural Sciences

    Author : Francisco Gonzalez; Sveriges lantbruksuniversitet.; [2017]
    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

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

    University dissertation from Stockholm : Karolinska Institutet, Department of Surgical Science

    Author : Nicholas Wyon; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  4. 4. Nicotinic transmission and drugs in anesthesia : Neuromuscular blocking agents and propofol - consequences for carotid body function

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Malin Jonsson; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  5. 5. Apnea and infection in neonates : Mediatory role of interleukin-1Beta and prostaglandin E2

    University dissertation from Stockholm : Karolinska Institutet, Department of Women's and Children's Health

    Author : Annika Olsson Hofstetter; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; respiration; interleukin-1Beta; prostaglandin E2; newborns; rodents; brainstem;

    Abstract : The breathing pattern of infants, particularly preterm infants, is often irregular or periodic and is frequently interrupted by apnea The latter represents a major concern in haematology, yet much remains unknown about its incidence, appearance, and pathophysiology. This thesis further characterizes cardiorespiratory activity in preterm infants during postnatal development and investigates the association between infection and apnea in neonates, focusing on the mediatory role of interleukin-1 and prostaglandin E2 in depressing central respiration.
