  2. 16. Neurogenesis in the adult brain from ballyhoo to sobriety

    Author : Helena Frielingsdorf; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology; Nerve growth factor; acetylcholine; GABA; learning; hippocampus; Neurogenesis; dopamine; substantia nigra;

    Abstract : New neurons are spontaneously generated in two regions of the adult brain, the hippocampus and the subventricular zone/olfactory bulb. The objective of this thesis was to study potential implications for adult neurogenesis in Alzheimer's (AD) and Parkinson's diseases (PD). READ MORE

  4. 17. Effects of Motion Sickness on Human Thermoregulatory Mechanisms

    Author : Gerard Nobel; Ola Eiken; Nigel A.S. Taylor; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motion Sickness; autonomic thermoregulation; behavioural thermoregulation; hypothermia; acetylcholine; histamine; Physiology; Fysiologi;

    Abstract : The presented studies were performed to investigate the effects of motion sickness (MS) on human autonomic and behavioural thermoregulatory mechanisms during cold stress and in a thermoneutral environment. The roles of histaminergic and cholinergic neuron systems in autonomic thermoregulation and MS-dependent dysfunction of autonomic thermoregulation were studied using a histamine-receptor blocker, dimenhydrinate (DMH), and a muscarine-receptor blocker, scopolamine (Scop).

  5. 18. Assessment of microvascular function by use of transdermal iontophoresis : methodological aspects

    Author : Erik Droog Tesselaar; Folke Sjöberg; Angela Shore; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Iontophoresis; Microcirculation; Laser-Doppler; Acetylcholine; Sodium nitroprusside; Pharmacodynamics; Pharmacokinetics skin; Physiology and pharmacology; Fysiologi och farmakologi;

    Abstract : Assessment of the microcirculation is of major importance in understanding the physiology of the vasculature and in assessing te vascular effects of pathological conditions such as diabetes, hypertension and sepsis. Transdermal iontophoresis can be used to non‐invasively introduce vasoactive drugs into the skin. READ MORE

  6. 19. Influence of neuromodulators and mechanical loading on pathological cell and tissue characteristics in tendinosis

    Author : Gloria Fong; Patrik Danielson; Alex Scott; Ludvig Backman; Paul Ackermann; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substance P; acetylcholine; transforming growth factor; neuromodulators; mechanical loading; tendinosis; anatomi; Human Anatomy;

    Abstract : Background: Tendinosis is a painful chronic, degenerative condition characterized by objective changes in the tissue structure of a tendon. Hallmark features in tendinosis tendons include increased number of cells (hypercellularity), extracellular matrix (ECM) degradation and disorganized collagen. READ MORE

  7. 20. Neuropeptides and neurotransmitters in keratocytes : importance in corneal wound healing processes

    Author : Marta Sloniecka; Patrik Danielson; May Griffith; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; substance P; acetylcholine; migration; proliferation; apoptosis; corneal stroma;

    Abstract : Background: The cornea is the outermost transparent layer of the eye and it is responsible for the majorityof the eye’s total focusing power. Keratocytes are the resident cells of the corneal stroma and their function isto produce extracellular matrix components and to take part in corneal healing after injury, which may occurdue to trauma, infection or surgery.
