   Författare :Rui Zheng; Karl Michaëlsson; Harri Sievänen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Metabolomics; LC-MS; sample quality; cohort; body composition; fracture; Medicinsk vetenskap; Medical Science; Bioinformatics; Bioinformatik; Epidemiologi; Epidemiology; Orthopaedics; Ortopedi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

   Sammanfattning : In this thesis, I evaluated the impact of pre-centrifugation sample management on the plasma metabolome, providing verification for the protocol used in a study where I applied metabolomics to better understand the role of body composition in fracture occurrence using a large population-based cohort.  In paper 1, I applied untargeted liquid chromatography-mass spectrometry (LC-MS) metabolomics analysis to plasma samples (n = 471) from healthy donors to predict and evaluate the effect of pre-centrifugation temperature and delay time on metabolomics data using a combination of random forest and generalized linear models.

3. 2. Effects of early probiotic supplementation in a pediatric setting : Focus on body composition, metabolism and inflammation

   Författare :Frida Karlsson Videhult; Christina E West; Olle Hernell; Inger Öhlund; Velmurugesan Arulampalam; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus paracasei ssp. paracasei F19; infants; children; growth; body composition; metabolism; follow-up; Pediatrics; pediatrik;

   Sammanfattning : We aimed to determine the short- and long-term effects on growth, body composition, metabolic and inflammatory markers following supplementation with the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) during weaning. LÄS MER

4. 3. Assessment of Body Composition Using Magnetic Resonance Imaging

   Författare :Joel Kullberg; Hans Frimmel; Tomas Gustavsson; Uppsala universitet; []
   Nyckelord :Bildanalys; Magnetic Resonance Imaging; Digital Image Processing; Segmentation; Morphology; Body Composition; Whole Body Imaging; Subcutaneous Adipose Tissue; Visceral Adipose Tissue; Anthropometry; Bildanalys;

   Sammanfattning : Methods for assessment of body composition allow studies of the complex relationships between body composition and the wellbeing of humans. The amount and distribution of adipose tissue is of great importance in these studies. LÄS MER

5. 4. Body Composition in Adolescents with Type 1 Diabetes : Aspects of Glycaemic Control and Insulin Sensitivity

   Författare :Stefan Särnblad; Jan Åman; Torsten Tuvemo; Jan Bolinder; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Type 1 diabetes mellitus; Adolescent; Body composition; Physical activity; Energy intake; Metformin; Insulin sensitivity; Pediatrik; Paediatric medicine; Pediatrisk medicin;

   Sammanfattning : Excessive weight gain has frequently been reported in adolescents with type 1 diabetes, especially in girls. In general, puberty is associated with reduced insulin sensitivity that is further diminished by overweight. The causes and consequences of excessive weight gain in adolescents with type 1 diabetes are not fully understood. LÄS MER

7. 5. Dietary Fatty Acids, Body Composition and Ectopic Fat : Results from Overfeeding Studies in Humans

   Författare :Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Linoleic acid; Palmitic acid; SFA; PUFA; Fatty acids; Body composition; Liver fat; Ectopic fat; Adipose tissue; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The aim of this thesis was to investigate the effects of dietary fatty acids on body composition and ectopic fat in humans, with emphasis on the role of the omega-6 polyunsaturated fatty acid (PUFA) linoleic acid (18:2n-6) and the saturated fatty acid (SFA) palmitic acid (16:0). The overall hypothesis was that linoleic acid would be beneficial compared with palmitic acid during overfeeding, as previously indicated in animals. LÄS MER
