2. 1. Calciumhomeostasis and Vitamin D in Obesity and Preeclampsia

   Author : Hella Hultin; Per Hellman; Ylva Pernow; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calcium homeostasis; vitamin D; preeclampsia; obesity; parathyroid hormone; Endocrine surgery; Endokrin kirurgi; Kirurgi; Surgery;

   Abstract : Normal physiological functioning is highly dependent of calcium and the concentration range is very narrow. Normal calcium levels are so crucial to survival that the body will de-mineralize bone if the levels are insufficient. A prerequisite for normal calcium uptake is a normal Vitamin D level. READ MORE

4. 2. Altered body composition in adults with complex congenital heart disease

   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

5. 3. Multimodal and multiscale characterization of bone and bone interfaces in health and disease

   Author : Chiara Micheletti; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone; osseointegration; characterization; mineralization; ultrastructure; diabetes; osteoporosis; MRONJ; surface functionalization; local drug delivery; titanium; bioactive glass; imaging; spectroscopy; microscale; nanoscale; micro-computed X-ray tomography; micro-Raman spectroscopy; scanning electron microscopy; transmission electron microscopy; PFIB-SEM tomography; electron tomography;

   Abstract : Seeing is believing. Our understanding of phenomena often involves their direct observation. However, bone architecture is challenging to visualize given its multi-level hierarchical organization. READ MORE

6. 4. New sensitive and specific methods for sex steroid measurements in rodent serum and tissues

   Author : Maria E. Nilsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex steroids; mass spectrometry; rodents;

   Abstract : Accurate measurement of sex steroids (androgens, estrogens, and progesterone) is essential in research and clinical settings for common diseases including osteoporosis, prostate cancer, breast cancer, and cardiovascular diseases. Sex steroids are not only produced in the gonads and adrenals but may also be locally synthesized in peripheral target tissues. READ MORE

7. 5. A prospective chohort study on bone formation and bone loss in ankylosing spondylitis

   Author : Anna Deminger; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ankylosing spondylitis; bone mineral density; spinal new bone formation; longitudinal cohort study;

   Abstract : Background and objectives: Patients with ankylosing spondylitis (AS) have an increased risk of bone loss with development of osteoporosis and vertebral fractures (VFs) but also spinal new bone formation with growth of bony spurs (syndesmophytes) between the vertebrae. Measurements of spinal bone mineral density (BMD) by the routine method dual-energy x-ray absorptiometry (DXA) in anteroposterior (AP) projection can be difficult to interpret due to the spinal new bone formation.
