  1. 36. The Biophysics of Na+,K+-ATPase in neuronal health and disease

    Författare :Evgeny E. Akkuratov; Hjalmar Brismar; Anita Aperia; Stefan Wennmalm; Poul Nissen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Na ; K -ATPase; NMDA receptor; ouabain; phosphoproteome; oligomerization; rapid-onset dystonia-parkinsonism; Biologisk fysik; Biological Physics;

    Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER

  3. 37. Diastereomeric Effects in DNA Binding – Biological and Biophysical Studies on Ruthenium Complexes

    Författare :Anna Mårtensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neighbor interaction; spectroscopy; diastereomeric; kinetics; antimicrobial activity; ruthenium; calorimetry; intercalation; DNA; enantiomer;

    Sammanfattning : Organic molecules, such as glucose and amino acids, are most often chiral. This means that their mirror-images are different, in the same way a left and a right hand are different from each other. For example, the DNA double helix in its standard form twists like a right-handed screw. LÄS MER

  4. 38. The Effect of Snow on Plants and Their Interactions with Herbivores

    Författare :Mikaela Torp; Johan Olofsson; Christa Mulder; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Snow; arctic ecosystem; plant-herbivore interactions; phenology; nitrogen; phenolics; experimental manipulation; natural gradient; inter-annual variability; Biology; Biologi;

    Sammanfattning : The ongoing climate changes are predicted to accelerate fast in arctic regions with increases in both temperatures and precipitation. Although the duration of snow cover is generally expected to decrease in the future, snow depth may paradoxically increase in those areas where a large amount of the elevated precipitation will fall as snow.

  5. 39. Host-parasite interactions in space and time

    Författare :Franziska Hildebrandt; Johan Ankarklev; Volker T. Heussler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Malaria; liver-stage infection; Toxoplasma; host-parasite interactions; spatial transcriptomics; single-cell omics; single-cell Dual-seq; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Unicellular parasites of the apicomplexan phylum have a considerable effect on global health and agriculture. Two prominent examples of this phylum include malaria causing parasites of the Plasmodium genus and the widely prevalent parasite Toxoplasma gondii. LÄS MER

  7. 40. Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions

    Författare :Leon Green; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sperm; Reproduction; Life-history Strategies; Local Adaptation; Fish; Invasion Biology; Salinity;

    Sammanfattning : Organisms are adapted to reproduce in their specific environment by a range of different traits. For many animals, reproduction is tied to specific conditions, that trigger or enable the reproductive events. This thesis deals with traits associated with reproduction, their functions and interactions with the environment. LÄS MER
