1. 16. Vitamin A regulated neuronal regeneration and homeostasis

   Författare :Sofia Håglin; Anna Berghard; Staffan Bohm; Leif Carlsson; Ola Hermanson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activity dependent; Adult stem cells; Ageing; CYP26B1; Homeostasis; Metaplasia; Neurogenesis; Olfactory epithelium; Regeneration; Respiratory epithelium; Retinoic acid; Sensory map; Vitamin A;

   Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER

3. 17. Jet lag and shiftwork : their effects on sleep & sleepiness

   Författare :Arne Lowden; Ulf Landström; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sleep; alertness; jet lag; activity; EEG; shift work; psykologi; Psychology;

   Sammanfattning : The aim of the studies was to describe the detailed sleep/wake patterns before, during, and after a period of work that forces individuals to deviate from their normal sleep/wake pattern. Possible countermeasures to experienced problems was evaluated in intervention designs. LÄS MER

4. 18. Modelling of molybdopterin-dependent enzymes

   Författare :Anders Thapper; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; enzymes; transition state; intermediate; mechanism; molybdopterin; density functional theory; model systems; oxygen atom transfer; molybdenum; tungsten; Oorganisk kemi; Chemistry; Kemi;

   Sammanfattning : The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. LÄS MER

5. 19. Physical performance and physical activity in the later stage post-stroke

   Författare :Christiane Carvalho; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebrovascular accident; exercise test; gait; healthy control; muscle strength; physical activity; physical therapy; rehabilitation; secondary prevention; stroke; walking;

   Sammanfattning : Aims: The overall purpose of this thesis was to increase knowledge about physical performance and activity in the later stage post-stroke by measuring walking performance in different environments coupled to muscle strength, cardiorespiratory fitness evaluation and self-reported physical activity. Methods: The studies reported in the thesis included a total of 83 subjects with prior stroke living in the community and 144 clinically healthy subjects from the same area. LÄS MER

7. 20. Studies on the deposition, bioavailability and systemic activity of glucocorticoids in man

   Författare :Lars Thorsson; Avdelningen för klinisk kemi och farmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; systemic activity; glucocorticosteroids; lung deposition; systemic availability; inhalation; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

   Sammanfattning : The local deposition, pharmacokinetics, and systemic activity of inhaled and intranasal glucocorticosteroids in different formulations and devices(ICSs) has been investigated. After nasal administration of the ICS budesonide (Bud), the systemic availability (F) was found to be significantly higher from an aqueous pump spray and from the powder inhaler Turbuhaler, than from a pressurized metered dose inhaler (pMDI), and the uptake process was slower and less complete with the pMDI formulation.
