1. 6. Seaweed Integrated Mariculture : Prospects and Constraints Towards Increased Sustainability

   Författare :Christina Halling; Max Troell; Nils Kautsky; Marc Verdegem; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integrated aquaculture; Gracilaria chilensis; Seaweed farming; salmon farming; nutrient reduction; dissolved nutrients; Chile; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : Increased global demand for seafood and stagnating catches from capture fisheries contributed to the doubling of aquaculture production taking place the last decade. Expansion within the aquaculture sector is expected to persist, and by many seen as the only mean to meet future demand for seafood. LÄS MER

3. 7. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

   Författare :Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. LÄS MER

5. 9. Food Quality for Zooplankton in Humic Lakes

   Författare :Kelly Gutseit; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; limnology; Hydrobiology; marine biology; Clear water lakes; Plankton; Seston; Elements; Fatty acids; Humic lakes; Food quality; Zooplankton; limnologi; akvatisk ekologi; aquatic ecology; Marinbiologi;

   Sammanfattning : Food quality affects growth, reproduction and community structure of zooplankton, and has implications for nutrient cycling and the transfer of energy and matter in aquatic food chains. While the issue of food quality in clear water lakes has received great recent attention, studies on food quality for zooplankton in humic lakes are scarce. LÄS MER

7. 10. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

   Författare :Oksana Zaushitsyna; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cells; Crosslinkers; PVA PEI; Immobilization; Biocatalysts; Biobased chemicals; Biotransformation; stress tolerance;

   Sammanfattning : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. LÄS MER
