1. 21. The expression and molecular functions of LRIG proteins in cancer and psoriasis

   Författare :Terese Karlsson; Håkan Hedman; Mikael Johansson; Roger Henriksson; Kim Jensen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LRIG1; LRIG2; LRIG3; LMO7 lung cancer; glioma; psoriasis; Oncology; onkologi;

   Sammanfattning : The leucine-rich repeats and immunoglobulin-like domains (LRIG) family consists of three integral membrane proteins that are important in human cancer. LRIG1 is a negative regulator of growth factor signaling. Its expression is associated with longer survival in several cancer types, and the gene has been shown to function as a tumor suppressor.

3. 22. Life History Strategies in Linnaea borealis

   Författare :Mikael Niva; Brita M. Svensson; P. Staffan Karlsson; Ørjan Totland; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Linnaea borealis; apex removal; apical dominance; clonal plant; hand pollination; matrix modelling; plant foraging; resorption efficiency; resorption proficiency; resource heterogeneity; shoot dynamics; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Sammanfattning : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. LÄS MER

4. 23. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain

   Författare :Mikael Wikgren; Karl-Fredrik Norrback; Rolf Adolfsson; Göran Roos; Thomas Karlsson; Brenda Penninx; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APOE; aging; atrophy; brain; cognition; cortisol; depression; hippocampus; HPA axis; MRI; stress; telomere length; white matter hyper-intensities.;

   Sammanfattning : Telomeres are the outermost parts of linear chromosomes. They consist of tandemly repeated non-coding short nucleotide sequences (TTAGGG in all vertebrates), in humans spanning over the last 2 to 15 kilobase pairs of the chromosome. Due to the end-replication problem, telomeres shorten with each cellular division. LÄS MER

5. 24. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

   Författare :Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

   Sammanfattning : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. LÄS MER

7. 25. Toxic Textiles : Towards Responsibility in Complex Supply Chains

   Författare :Natasja Börjeson; Magnus Boström; Mikael Karlsson; Sverker Molander; Södertörns högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Responsibility; Sustainability; Supply Chain Management; Governance; Responsibilisation; CSR; Complexity; Uncertainty; Chemicals; Textiles; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Sammanfattning : The governance of the environmental and health problems that follow in the wake of globalised trade is one of the great contemporary challenges. One of these challenges is the management of chemical pollution and associated risks, and one sector facing this challenge is the textile industry, which has complex supply chains spread across continents.
