2. 1. Cerebrovascular accidents associated with aortic manipulation during cardiac surgery

   Author : Patrik Boivie; Gunnar Engström; Magnus Hansson; Henrik Ahn; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; aortic atherosclerosis; aortic cannulation; aortic cross-clamp; cardiac surgery; cerebral protection; cerebrovascular accidents; epiaortic ultrasound; intra-aortic filter; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Abstract : Background: Despite the successful development in cardiac surgery, cerebrovascular accidents (CVA) remain a devastating complication. Aortic atherosclerosis has been identified as a major risk factor for CVA. READ MORE

4. 2. Functional and structural properties of eukaryotic DNA polymerase epsilon

   Author : Olga Chilkova; Erik Johansson; Per Elias; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; eukaryotic DNA replication; DNA polymerase epsilon; protein-DNA interaction; Biochemistry; Biokemi;

   Abstract : In eukaryotes there are three DNA polymerases which are essential for the replication of chromosomal DNA: DNA polymerase alpha (Pol alpha), DNA polymerase delta (Pol delta) and DNA polymerase epsilon (Pol epsilon). In vitro studies of viral DNA replication showed that Pol alpha and Pol delta are sufficient for DNA replication on both leading and lagging DNA strands, thus leaving the function of Pol epsilon unknown.

5. 3. Peptidoglycan recognition proteins in Drosophila melanogaster

   Author : Thomas Werner; Dan Hultmark; Bruno Lemaitre; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Drosophila; PGRP; peptidoglycan; pattern recognition; imd; Relish; isoform; RNAi; mbn-2; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : The fruit fly Drosophila melanogaster is an excellent model organism to study the innate immune response, because insects and mammals share conserved features regarding the recognition and destruction of microorganisms and Drosophila is easily accessible to genetic manipulation. In my present study, I identified a new family of pattern recognition molecules for bacterial peptidoglycan in Drosophila, the Peptidoglycan Recognition Proteins (PGRP). READ MORE

6. 4. Regulation of NF-κB by Calmodulin

   Author : Åsa Antonsson; Thomas Grundström; Ylva Engström; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; NF-κB; calmodulin; transcription; calcium; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Abstract : Cells experience numerous external signals which they must respond to. Such signals arriving at the cell surface are transduced via various signal transduction pathways and often ultimately result in regulation of transcription. READ MORE

7. 5. Interaction between humans and car seats : studies of occupant seat adjustment, posture, position, and real world neck injuries in rear-end impacts

   Author : Bertil Jonsson; Ulf Björnstig; Mats Svensson; Anders Kullgren; Umeå universitet; []
   Keywords : Surgery; backset; Whiplash; rear-end impact; seated posture; seated position; bioRID; Kirurgi; Surgery; kirurgi;

   Abstract : Background: The latest generation of rear-end whiplash protection systems, as found in the WHIPS Volvo and SAHR Saab, have reduced injury rates by almost 50% in comparison with the previous generation of seat/head restraint systems. Occupant behaviour, such as seated posture and seat adjustment settings, may affect the injury risk. READ MORE
