4. 7. Weighted Analysis of Microarray Experiments

   Author : Anders Sjögren; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA microarray; differential expression; gene expression; quality control QC ; quality assurance QA ; quality assessment; generalised linear model; empirical Bayes; weighted moderated statistic; invalid p-value; heteroscedasticity; WAME; heteroscedasticity;

   Abstract : DNA microarrays are strikingly efficient tools for analysing gene expression for large sets of genes simultaneously. The aim is often to identify genes which are differentially expressed between some studied conditions, thereby gaining insight into which cellular mechanisms are differently active between the conditions.

5. 8. Injuries among the elderly : study of fatal and non-fatal injury events

   Author : Harmeet Sjögren; Ulf Björnstig; Anders Eriksson; Pat Waller; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elderly; injury; prevention; traffic; home; fall; crash; disease; bicyclist; pedestrian; cost; vehicle;

   Abstract : In view of the expected increase in the proportion of elderly in the population in most western countries, we studied injuries among the elderly (>60 years) by investigating hospital-treated injuries in inpatients and outpatients, and fatal injuries.One-year Hospital Injury Data - Even though the elderly made up only 15% of the injured in one year, they accounted for 42% of the total cost of trauma medical care, showing that injuries among the elderly place a disproportional burden on the health care system.

6. 9. Oral anticoagulation and stroke risk

   Author : Vilhelm Sjögren; Anders Själander; Per Wester; Peter J Svensson; Mia von Euler; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; warfarin; atrial fibrillation; dabigatran; rivaroxaban; apixaban; low-molecular-weight heparin; bridging;

   Abstract : Background: The risk of ischaemic stroke in patients with atrial fibrillation (AF) and mechanical heart valve (MHV) prostheses can be reduced by oral anticoagulation (OAC), which increases the risk of serious bleeding. The aims of this thesis were [1] to find out how effective and safe warfarin is where treatment quality is high, i.e. READ MORE

7. 10. Zirconia as a biomaterial for odontological applications : effects of composition and manufacturing processes on fracture resistance

   Author : Anders Sundh; Göran Sjögren; Krister Nilner; Umeå universitet; []
   Keywords : CAD CAM; ceramics; HIPing; Mg-PSZ; veneering; Y-TZP; zirconia;

   Abstract : Background: Ceramics have long been amongst the most biocompatible materials known but their mechanical properties have limited their use. During the past few decades zirconia has aroused particular interest as a biomaterial because of its greater flexural strength, fracture resistance and toughness compared to other bioceramics.
