  1. 1. Functional Metallic Glasses

    Author : Ansar Masood; Lyubov Belova; K. Venkat Rao; Lars Arnberg; KTH; []
    Keywords : Bulk Metallic glasses; glass forming ability; soft magnetism; thin films; magnetic properties; magnetic hardening; plasticity; biocompatibility;

    Abstract : For decades, Metallic Glass, with its isotropic featureless structure while exhibiting outstanding mechanical properties was possible only at a high rate of quenching and with at least one dimension in the submicron regime.  This limitation was overcome with the discovery of Bulk Metallic glasses, BMGs, containing three or more elements following the additional two empirical rules of optimum geometric size differences and negative energy of mixing among the constituent elements.

  2. 2. Plasticity and Inflammation following Traumatic Brain Injury

    Author : Anders Hånell; Niklas Marklund; Lars Hillered; Nikolaus Plesnila; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic Brain Injury; plasticity; inflammation; Nogo receptor; EphA4; IL-1β; Neurosurgery; Neurokirurgi; Neuroscience; Neurovetenskap;

    Abstract : Traumatic Brain Injury (TBI) mainly affects young persons in traffic accidents and the elderly in fall accidents. Improvements in the clinical management have significantly improved the outcome following TBI but survivors still suffer from depression, memory problems, personality changes, epilepsy and fatigue.

  3. 3. From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus

    Author : Anna-Lisa Wrange; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : environmental change; salinity; marine; invertebrates; evolution; plasticity; population genetics; functional genomics; barnacle; osmoregulation;

    Abstract : How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts on marine ecosystems worldwide. READ MORE

  4. 4. Brain Plasticity and Upper Limb Function After Stroke: Some Implications for Rehabilitation

    Author : Påvel Lindberg; Jörgen Borg; Hans Forssberg; Margareta Engardt; Cornelius Weiller; Uppsala universitet; []
    Keywords : Neurosciences; Stroke; Upper Limb; Brain Plasticity; Functional MRI; Diffusion Tensor Imaging; Transcranial Magnetic Stimulation; Neurovetenskap;

    Abstract : Neuroimaging and neurophysiology techniques were used to study some aspects of cortical sensory and motor system reorganisation in patients in the chronic phase after stroke. Using Diffusion Tensor Imaging, we found that the degree of white matter integrity of the corticofugal tracts (CFT) was positively related to grip strength. READ MORE

  5. 5. Neurotransmission and functional synaptic plasticity in the rat medial preoptic nucleus

    Author : Evgenya Malinina; Staffan Johansson; Eric Hanse; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic plasticity; GABA; glutamate; L-type Ca2 channel; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : Brain function implies complex information processing in neuronal circuits, critically dependent on the molecular machinery that enables signal transmission across synaptic contacts between neurons. The types of ion channels and receptors in the neuronal membranes vary with neuron types and brain regions and determine whether neuronal responses will be excitatory or inhibitory and often allow for functional synaptic plasticity which is thought to be the basis for much of the adaptability of the nervous system and for our ability to learn and store memories.
