1. 6. Metabolic Significance of Systemic DHA Deficiency

   Författare :Anna Maria Pauter; Anders Jacobsson; Bernadette Delplanque; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

   Sammanfattning : Fatty acid composition in the body displays a high level of heterogeneity and can rapidly respond to changes in diet regime or to starvation. Homeostasis of the level of certain fatty acids is an important factor for maintenance of structural integrity as well as for proper signaling within the organism. LÄS MER

3. 7. β-adrenergic signalling and novel effects in skeletal muscle

   Författare :Anette I. Öberg; Tore Bengtsson; Jon Arch; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

   Sammanfattning : Skeletal muscles have, due to their large mass, a big impact on the whole body metabolism. There are many signals that can regulate the functions of skeletal muscles and one such signal is activation of α- and β-adrenoceptors (α- and β-ARs) by epinephrine and norepinephrine. LÄS MER

4. 8. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

   Författare :Karin Willquist; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

   Sammanfattning : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. LÄS MER

5. 9. The psycho-metabolic consequences of sleep loss in people

   Författare :Lieve T. van Egmond; Christian Benedict; Veronica Witte; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sleep; nutrition; metabolism; sleep deprivation; sex differences; weight differences; obesity; cognition; mediterranean diet; brain health; social evaluation; night work; occupational performance; emotion; vigilance; energy balance; diet; elderly; Fysiologi; Physiology; Nutrition; Nutrition; Neurology; Neurologi; Psychiatry; Psykiatri; Geriatrics; Geriatrik; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Night work is vital for maintaining our 24/7 society; however, in the long run, it may have adverse health consequences like obesity and Alzheimer’s disease. By performing one of the most extensive experimental in-laboratory studies to date, I sought to investigate how sleep deprivation impacts important features like how a person responds to others and how well a person can sustain attention and wakefulness during simulated night work.

7. 10. Effects of growth hormone on bone tissue in transgenic mice

   Författare :Jonas Sandstedt; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; bone; ovariectomy; orchidectomy; growth; Interleukin-6; titanium; transgenic mice;

   Sammanfattning : Growth hormone (GH) affect bone-tissue in both humans and rodents. Also sex steroids are important for growth and the maintenance of normal bone physiology. The specific aims of this study were to investigate how high levels of GH affects bone tissue in mice and to determine whether these effects are dependent on an intact gonadal function. LÄS MER
