  2. 1. Sources and Diagnostics for Attosecond Science

    Author : Miguel Miranda; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse Compression; High-order Harmonic Generation; Ultrafast; Ultrashort; Attosecond; Femtosecond; Pulse Characterization; Fysicumarkivet A:2012:Miranda;

    Abstract : Ultrafast science refers to physical events that happen on the femtosecond (1 fs=10^-15 s) and attosecond (1 as=10^-18 s) timescales. Generation of attosecond pulses is usually achieved by interacting high-intensity femtosecond pulses with matter (typically gases), in a process called high-order harmonic generation (HHG).

  4. 2. Gene expression profiling in autoimmune diseases : a story of ups and downs

    Author : Miranda Houtman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Autoimmune diseases are believed to arise from a combination of genetic and environmental factors that affect normal function of immune cells. In this thesis, we studied the functional role of genetic variants, in peripheral blood cells, that relate to rheumatoid arthritis (RA) and myositis by gene expression profiling. READ MORE

  5. 3. Paracrine control of glucagon secretion in the pancreatic α-cell: Studies involving optogenetic cell activation

    Author : Caroline Miranda; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Glucagon; α-Cell; Optogenetics;

    Abstract : ABSTRACT The mechanisms controlling glucagon secretion by α-cells in islets of Langerhans were studied. We generated mice with the light-activated ion channel ChR2 specifically expressed in β-, α-, and δ-cells, and explored the spatio-temporal relationship between cell activation and glucagon release.

  6. 4. Biological control of diamondback moth : the roles of predators, parasitoids and insecticides

    Author : Freddy Miranda; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The diamondback moth Plutella xylostella L. (Lepidoptera: Plutellidae) is a serious pest of economically important crucifer crops such as cabbage. The moth has developed resistance to all tested insecticides and further studies on the potential role of factors affecting P. xylostella survival, including natural enemies, are urgently needed.

  7. 5. Neurotoxicity after poisonings with organophosphate pesticides in Nicaragua

    Author : Jamilette Miranda; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In Nicaragua rates of acute human poisonings caused by pesticides, in spite of significant underreporting, are among the highest in the world. Hence the unrestricted availability of pesticides and their misuse, as well as the continuous increase in annual imports of pesticides are reasons for public health concern. READ MORE
