2. 1. Fat-IBC : A New Paradigm for Intra-body Communication

   Author : Noor Badariah Asan; Robin Augustine; Thiemo Voigt; Ali Khaleghi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fat-Intrabody Communication; Fat Tissue; Microwave; Propagation; Data Packet Reception; Ex-vivo; Phantom; Communication; Reliability; Implants; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Abstract : In the last two decades, a significant development in the field of medical technology occurred worldwide. This development is characterized by the materialization of various body implants and worn devices, that is devices attached to the body. READ MORE

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

   Author : Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. Human body composition. Reference data and anthropometric equations. The metabolic syndrome and risk

   Author : Ingrid Larsson; Göteborgs universitet; []
   Keywords : adults; anthropometry; atherosclerotic morbidity; body composition; body fat; cardiovascular disease; DEXA; dual energy x-ray absorptiometry; fat-free mass; FFM; humans; metabolic syndrome; morbidity; mortality; prediction equations; randomly selected sample; reference data; sagittal trunk diameter; TBK; total body potassium; waist circumference;

   Abstract : The determination of body composition is a key to the understanding of the relation between obesity and disease. In order to evaluate body composition data, reference values are needed. Since methods with high validity and reproducibility are expensive and often time consuming, simpler techniques based on anthropometry are needed. READ MORE

6. 4. Separation of Water and Fat Signal in Magnetic Resonance Imaging : Advances in Methods Based on Chemical Shift

   Author : Johan Berglund; Joel Kullberg; Lars Johansson; Håkan Ahlström; Zhi-Pei Liang; Uppsala universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Magnetic resonance imaging; digital image reconstruction; chemical shift imaging; water and fat separation; Dixon method; fat suppression; quantitative MRI; whole-body MRI; fatty acid composition; fat unsaturation; triglycerides; adipose tissue; liver fat; T2* mapping; Radiology; Radiologi; Radiology; Radiologi;

   Abstract : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. READ MORE

7. 5. Altered body composition in adults with complex congenital heart disease

   Author : Karna Johansson; Camilla Sandberg; Bengt Johansson; Thomas Mooe; Mats Börjesson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adults with complex congenital heart disease; ACHD; body composition; skeletal muscle; lean mass; muscular strength; sarcopenia; bone; bone mass; bone mineral density; bone health; osteoporosis; fat; fat mass; obesity; Vuxna med medfödda hjärtfel; vuxna med komplexa medfödda hjärtfel; komplexa medfödda hjärtfel; kroppssammansättning; skelettmuskel; styrka; sarkopeni; ben; benmassa; bendensitet; osteoporos; fett; fettmassa; obesitas; kardiologi; Cardiology;

   Abstract : Introduction: Thanks to achievements in paediatric heart surgery and medicine, the population of adults with surgically repaired or palliated congenital heart defects is growing. Many of these adults have reduced exercise capacity, weaker muscular strength and shorter height, all of which suggest an altered body composition. READ MORE
