  2. 11. Cosmic clues from astrophysical particles

    Author : Francesca Capel; Christer Fuglesang; Michael Unger; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : Ultra-high-energy cosmic rays (UHECRs) are charged particles that have been accelerated to extreme energies, such that they are effectively travelling at the speed of light. Interactions of these particles with the Earth’s atmosphere lead to the development of extensive showers of particles and radiation that can be measured with existing technology. READ MORE

  4. 12. The Free Fatty Acid Receptor GPR40 - expression and role in islet hormone secretion

    Author : Erik Flodgren; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; GPCR; Glucagon; GPR40; Insulin; Free fatty acid; Endokrinologi; sekretion; diabetologi;

    Abstract : Type 2 diabetes (T2D) is a serious condition of growing proportions. Developing via an increasing imbalance between insulin sensitivity in the peripheral tissues and insulin release from pancreatic beta-cells, it ultimately renders the individual incapable of regulating the blood glucose concentration, e.g. after a meal.

  5. 13. Involvement of Eicosanoid Signaling in Intestinal Epithelial Cell Survival

    Author : John Öhd; Malmö Experimentell patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General pathology; Tcf Lef; Bcl-2 family; b-catenin; 5-LO; apoptosis; cell survival; colorectal cancer; COX-2; LTD4; CysLT1 R; pathological anatomy; Patologi allmän ; patologisk anatomi;

    Abstract : Eicosanoids are known to be involved in many different aspects of eukaryotic physiology and pathology. Notably, over the past 10 years much attention has been given to cyclooxygenase-2 (COX-2) due to its involvement in colorectal cancer. Less is known about the other major branch of arachidonic acid metabolism, namely the lipoxygenases (LO). READ MORE

  6. 14. Diverse cyclic dinucleotide signals regulate Escherichia coli lifestyle transition

    Author : Fengyang Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Bacteria have the ability to change their lifestyle to adapt to various environmental conditions. Cyclic dinucleotides (cDNs) are ubiquitous second messengers that can regulate fundamental lifestyle switches, such as motility versus sessility and acute versus chronic virulence, in bacteria.

  7. 15. Exploring the Universe Using Neutrinos : A Search for Point Sources in the Southern Hemisphere Using the IceCube Neutrino Observatory

    Author : Rickard Ström; Allan Hallgren; Olga Botner; Chad Finley; Lawrence R. Sulak; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astroparticle physics; neutrino sources; neutrino telescopes; IceCube; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Neutrinos are the ideal cosmic messengers, and can be used to explore the most powerful accelerators in the Universe, in particular the mechanisms for producing and accelerating cosmic rays to incredible energies. By studying clustering of neutrino candidate events in the IceCube detector we can discover sites of hadronic acceleration. READ MORE
