1. 26. Assessing the toxic impact of chemicals using bacteria

   Författare :Jenny Gabrielson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Bacteria; toxicity testing; ecotoxicity; phylogenetic diversity; growth inhibition;

   Sammanfattning : There is a considerable backlog in the testing of new chemical compounds for their ecotoxic properties, mostly due to the lack of appropriate testing methods. In addition, there is a vivid debate today about the test endpoint for many of the existing methods. LÄS MER

3. 27. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

   Författare :Ramnath Lakshmanan; Gunaratna Kuttuva Rajarao; Erik Dahlquist; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

   Sammanfattning : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. LÄS MER

4. 28. Hazard Identification of Anti-fouling Paints and Contaminated Sediments by the Use of Biological Tests in Brackish Water

   Författare :Jenny Karlsson; Britta Eklund; Magnus Breitholtz; Göran Dave; Stockholms universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anti-fouling paints; Toxicity tests; Hazard identification; Sediment toxicity; Ceramium tenuicorne; Nitocra spinipes; Environmental engineering; Miljöteknik; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Ecotoxicological test methods are important tools in environmental risk assessment to investigate possible adverse effects that chemical substances may cause to aquatic ecosystems. The main aim of this doctoral thesis was to identify potential toxicity (hazard) of anti-fouling compounds and paints as well as contaminated sediments. LÄS MER

5. 29. Microfluidic biosensor systems for cardiotoxicity assaying

   Författare :Gunnar Bergström; Carl-Fredrik Mandenius; Nate Robinson; Staffan Nilsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Toxicity screening is an important part of pharmaceutical development and early detection of toxic side effects provide the opportunity for early redesign or termination of unfeasible projects. Today toxicity testing is relying on experiments on animals. LÄS MER

7. 30. Posterior reversible encephalopathy syndrome and other severe central nervous system adverse events in the NOPHO ALL2008 protocol : clinical and radiological findings, genetic risk factors and prognosis

   Författare :Stavroula Anastasopoulou; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: The advances in the therapeutic protocols for pediatric acute lymphoblastic leukemia (ALL) have led to a current survival rate of more than 90% in developed countries. Treatment periods are, however, long and marked by complications and toxicity that may challenge treatment outcomes and quality of life for patients. LÄS MER
