   Författare :Christos Karefylakis; Eva Rask; Stefan Särnblad; Kerstin Landin-Wilhelmsen; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vitamin D; obesity; Roux-en-Y gastric bypass; secondary hyperpara-thyroidism; anemia; iron deficiency; body composition; cardiorespiratory fitness; Vitamin D C3 epimer;

   Sammanfattning : Vitamin D has received much attention in recent years due to the re-emergence of vitamin D deficiency as a global health issue along with increasing evidence indicating that 1,25-dihydroxivitamin D, the hormonally active form of vita-min D, not only acts in calcium and bone metabolism but also generates ex-traskeletal biological responses.In this thesis, the role of vitamin D in obesity and other associated condi-tions has been studied.

3. 22. Formation of Thiolated Nucleosides in tRNA in Salmonella enterica serovar typhimurium

   Författare :Hans Lundgren; Glenn Björk; Charles Lauhon; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : tRNA; modified nucleosides; thiolation; sulfur metabolism; Salmonella; Molecular biology; Molekylärbiologi;

   Sammanfattning : The presence and synthesis of transfer RNA (tRNA) is highly conserved in all organisms and a lot of genetic material is dedicated to its synthesis. tRNA contains a large number of modified nucleosides and several diverse functions have been found but much about their function is still unknown.

   Sammanfattning : Epilepsy is a common neurological disease affecting 6 million people in Europe. Early prevention and accurate diagnosis and treatment are of importance to obtain seizure freedom. In this thesis new applications of carbon-11-labelled tracers in PET and autoradiographic studies were explored in focal epilepsy. LÄS MER

5. 24. Root system of seabuckthorn (Hippophaë rhamnoides L.) : morphology, metabolism and gene expression

   Författare :Syed Rehmat Ullah Shah; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Nutrient availability is one of the limiting factors for plant growth and development, and the nutrients on Earth are unevenly distributed. To overcome this, plants adapt by modifying their morphology and physiology, especially of the root system. Seabuckthorn is a small tree growing in temperate regions of Europe and Asia. LÄS MER

7. 25. Dietary intake, nutritional status and energy metabolism in adolescents with severe obesity - Effects of gastric bypass surgery

   Författare :Pia Henfridsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Roux-en-Y gastric bypass; metabolic bariatric surgery; adolescents; dietary assessment; body composition; micronutrient intake; medication adherence; vitamin deficiencies; energy intake; energy expenditure; doubly labeled water;

   Sammanfattning : Background and aims: Roux-en-Y gastric bypass is an effective obesity treatment in adults and is becoming established in adolescents. Information is scarce on long-term changes in dietary intake, nutritional status and energy metabolism in adolescents undergoing gastric bypass. LÄS MER
