  1. 1. Preservation of Marine Reptile Soft Parts: Reconstructing the Life and Death of Ancient Leviathans

    Author : Randolph De La Garza; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular paleontology; Taphonomy; Soft-tissues; Lagerstätten; Skin; Sea Turtle; Ichthyosaur; Fur Formation; Posidonia Shale; Paleobiology; Marine Reptiles;

    Abstract : Marine reptiles constitute a diverse group of secondarily aquatic tetrapods that have inhabited the world’s oceans for the greater part of the last 250 million years. While certain large-scale anatomical changes have been observed through progressive alterations of their skeletal morphology (e.g. READ MORE

  2. 2. Transthyretin and the transthyretin-related protein: A structural study

    Author : Erik Lundberg; A. Elisabeth Sauer-Eriksson; Lennart Sjölin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Transthyretin-related protein; X-ray crystallography; Protein structure; Amyloidosis; Structural biology; Strukturbiologi;

    Abstract : Transthyretin (TTR) is one of several proteins involved in amyloid disease in humans. Unknown conformational changes of the native state of TTR result in aggregation of TTR molecules into amyloid fibrils, which accumulate in extracellular tissues. This may result in different clinical symptoms, e.g. READ MORE

  3. 3. Birds and Borrelia

    Author : Björn Olsen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Ixodes ticks; Birds; Epidemiology; Zoonotisk ekologi; Virology; Mikrobiologi;

    Abstract : The Lyme disease causing spirochaete Borrelia burgdorferi sensu lato is transmitted by ticks within the genus Ixodes. These ticks are liberal host seekers and parasitise mammals, birds and reptiles.Prior to this study, the distribution of I. ricinus ticks and Lyme disease was thought to be restricted to the southern half of Sweden.

  4. 4. Structural and functional properties of transthyretin

    Author : Anders Karlsson; A. Elisabeth Sauer-Eriksson; Salam Al-Karadaghi; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Amyloidosis; X-ray crystallography; Protein structure; Protein; Structural biology; Strukturbiologi;

    Abstract : The hereditary transthyretin (TTR) amyloidoses are rare, and in severe cases, fatal disorders caused by mutations in the TTR gene. The clinical picture is diverse, involving neuropathies and myopathies, and mainly depends on the causative mutation and the sites and rates of amyloid deposition. READ MORE
