  2. 1. Sensory neuronal protection & improving regeneration after peripheral nerve injury

    Author : Andrew McKay Hart; Mikael Wiberg; Angus McGrouther; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell death; TUNEL; optical disection; dorsal root ganglion; peripheral nerve; nerve conduit; Schwann cell; glial growth factor; leukaemia inhibitory factor; acetyl-L-carnitine; N-acetyl-cysteine; Neurovetenskap; Neurology; Neurologi; neurokirurgi; Neurosurgery;

    Abstract : Peripheral nerve trauma is a common cause of considerable functional morbidity, and healthcare expenditure. Particularly in the ~15% of injuries unsuitable for primary repair, standard clinical management results in inadequate sensory restitution in the majority of cases, despite the rigorous application of complex microsurgical techniques.

  4. 2. Molecular factors influencing nerve growth : studies on the developing rodent trigeminal ganglion and tooth pulp

    Author : Christina Lillesaar; Ted Ebendal; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The adult tooth pulp has a rich protective sensory innervation from the trigeminal ganglion (TG). The developmental establishment of this exclusively nociceptive innervation is not fully understood today. READ MORE

  5. 3. Simplified Routines for Sample Preparation and Analysis of Chemical Warfare Agent Degradation Products

    Author : Raja Subramaniam; Calle Nilsson; Paula Vanninen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nerve agents; Alkyl alkylphosphonic acids; Solid phase derivatization; Fluorinated diazomethane reagent; High-energy collision induced dissociation; CID MS MS library; analytisk kemi; Analytical Chemistry;

    Abstract : The thesis describes the development of new and improved methods for analyzing degradation markers from organophosphorus Chemical Warfare Agents (CWAs). Paper I and II describes an innovative and significantly improved method for the enrichment, derivatization (trimethysilylation) and GC-MS analysis of a broad range of organophosphorus CWAs degradation markers, namely the alkylphosphonic acids and a zwitterionic compound.

  6. 4. Route attribution of chemical warfare agents : Retrospective classification of unknown threat samples

    Author : Karin Höjer Holmgren; Johan Dahlén; Crister Åstot; Peter Haglund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Impurity profiling; Chemical attribution signature; Route sourcing;

    Abstract : Although chemical warfare agents (CWAs) are prohibited under international law, there have been numerous crimes that violates the 1997 Chemical Weapons Convention (CWC) during the last decade, especially in the civil war in Syria where sarin, mustard gas and chlorine have all been used. CWAs have also been used in political assassinations and attempts thereof. READ MORE

  7. 5. Mechanisms and improvements of cell transplantation for nerve repair

    Author : Kai-Hei Tse; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenchymal stem cells; microporous scaffold; biomaterials; ischemia; cell death; brain derived neurotrophic factor;

    Abstract : Trauma to the nervous system is a frequent clinical problem and new approaches to nerve repair are required. Autologous cell transplantation together with a suitable scaffold material could be used to create a bio-active artificial nerve graft to enhance regeneration. READ MORE
