1. 1. On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study

   Författare :Dan-Åke Wälivaara; Göteborgs universitet; []
   Nyckelord :periapical surgery; ultrasonic preparation; IRM; thermoplasticized gutta-percha; Super-EBA; mineral trioxide aggregate; root-filling status; lesion size; lesion type;

   Sammanfattning : Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second treatment alternative might be a periapical surgery procedure. LÄS MER

3. 2. Structure of eukaryotic DNA polymerase epsilon and lesion bypass capability

   Författare :Nasim Sabouri; Erik Johansson; Lars Thelander; Ola Hammarsten; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DNA polymerase epsilon; DNA replication; Okazaki fragment; Translesion synthesis; DNA lesion; dNTP; Biochemistry; Biokemi;

   Sammanfattning : To transfer the information in the genome from mother cell to daughter cell, the DNA replication must be carried out only once and with very high fidelity prior to every cell division. In yeast there are several different DNA polymerases involved in DNA replication and/or DNA repair. LÄS MER

4. 3. Towards a detailed understanding of the red blood cell storage lesion : and its consequences for in vivo survival following transfusion

   Författare :Andreas Hult; Christer Malm; Per-Arne Oldenborg; Martin L. Olsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Red blood cell; erythrocyte; transfusion; macrophage; phagocytosis; storage lesion; eryptosis; Class A scavenger receptor; transfusion medicine; transfusionsmedicin;

   Sammanfattning : Red blood cells (RBCs) are vital for oxygen delivery to tissues and constitute the vast majority of all cells in blood. After leaving the red bone marrow as mature cells, RBCs have a lifespan of approximately 120 days before they are removed from the circulation by macrophages, mainly in the spleen and liver. LÄS MER

5. 4. Upper and Lower Motoneuron Lesions in Tetraplegia - Diagnostic and Therapeutic Implications of Electrical Stimulation

   Författare :Ines Bersch; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrical stimulation; Tetraplegia; Upper motoneuron lesion; Lower motoneuron lesion; Motor point topography; Nerve transfer;

   Sammanfattning : The overall objective of this thesis was to improve outcomes and predictability of the treatment of upper extremity function in patients with cervical spinal cord injury and tetraplegia by advancing the diagnostic and therapeutic tools employed in upper and lower motor neuron lesions. An overview is presented of the current knowledge about the principles of electrical stimulation and its usefulness and proven effects on the upper limb. LÄS MER

7. 5. On the Site of the Lesion in Konzo : Clinical and Neurophysiological Studies on a Non-Progressive Upper Motor Neuron Disorder

   Författare :Desire Tshala-Katumbay; Andrew Eisen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Konzo; upper motor neuron diseases; WHO criteria; electroencephalography; evoked potentials; brain involvement; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

   Sammanfattning : Konzo is a permanent spastic para/tetraparesis occurring in undernourished populations in Africa relying on insufficiently processed bitter cassava, which contains cyanogenic compounds, as staple food. Its pathogenetic mechanism is unknown. Our studies aimed at clarifying the lesion in konzo. LÄS MER
