2. 6. Gastrointestinal symptoms in chronic renal failure. Prevalence and pathophysiological mechanisms

   Author : Hans Strid; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic renal failure; end-stage renal disease; gastrointestinal symptoms; overuse; proton pump inhibitors; H2-receptor antagonists; quality of life; manometry; small intestinal bacterial overgrowth; gastric emptying; Helicobacter pylori;

   Abstract : Chronic renal failure (CRF) has a varying etiology and is characterised by an increasing accumulation of toxic metabolic waste products in the blood. Malnutrition is a common finding in uraemic patients and is regarded as a marker for morbidity and mortality. Many factors, including gastrointestinal (GI) symptoms, lead to malnutrition in CRF.

4. 7. Predominant failure mechanisms at the Kiirunavaara mine footwall

   Author : Mikael Svartsjaern; Diego Mars Ivars; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The Luossavaara-Kiirunavaara Aktiebolag (LKAB) Kiirunavaara mine is a large scale sub-level caving (SLC) mine in northern Sweden. The use of SLC as a mining method inherently causes significant rock mass movements above the extraction level. READ MORE

5. 8. Mechanisms of cell diversification

   Author : Christopher Winston Uhde; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Cell identity and function is determined by the intrinsic wiring of the gene regulatory network that endows progenitors with the competence to respond appropriately to extrinsic cues in a spatiotemporally-dependent manner. One such class of cues, morphogens, instruct cells in their identity by virtue of a concentration gradient, but how this is interpreted at gene regulatory levels to result in sharp and robust boundaries of gene expression is poorly understood.

6. 9. Caving mechanisms for a non-daylighting orebody

   Author : Sraj Umar Banda; Jonny Sjöberg; Björn Nilsen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel caving; numerical analysis; laser scanning; seismic data; large-scale structure; rock mass characterization; failure mechanism; discontinuum modeling; continuum modeling; caving analysis; voronoi modeling; bonded block model; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass. READ MORE

7. 10. Atrial fibrillation – on its trigger mechanisms, risks and consequences

   Author : Dritan Poci; Göteborgs universitet; []
   Keywords : acute coronary syndromes; atrial fibrillation; AV junctional ablation; CHADS2 score; electrical cardioversion; mortality; stroke; trigger mechanisms;

   Abstract : Background: Atrial fibrillation (AF) frequently impairs quality of life, but in long-term it is associated with an increased morbidity and mortality. Persistent AF may cause changes in the sinus node function, and if converted to sinus rhythm (SR), there is a substantial risk of recurrence of AF. READ MORE
