  1. 11. Apoptosis-related mechanisms in the immature brain after hypoxia-ischemia

    Author : Xiaoyang Wang; Göteborgs universitet; []
    Keywords : hypoxia-ischemia; neonatal; caspase; ERK; XIAP; EPO; asialoEPO; brain;

    Abstract : Aims: To characterize the activation of caspases-3 and extracellular signal-regulated kinase (ERK) in the neonatal brain after hypoxia-ischemia (HI) injury and evaluate the neuroprotective effect of X-linked inhibitor of apoptosis (XIAP) protein, erythropoietin (EPO) and the non-erythropoietic derivative asialoEPO. Methods: Seven-day-old rats or 9-day-old mice were subjected to HI. READ MORE

  2. 12. Ischemic and Hypoglycemic Brain Damage, Involvement of the Mitochondrial Permeability Transition Pore

    Author : Hans Friberg; Lund Wallenberg Neurocentrum; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondrial permeability transition pore; mitochondria; apoptosis; neuronal death; brain; ischemia; hypoglycemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : Brain damage from ischemia-reperfusion and hypoglycemia are major causes of morbidity and mortality. Therapeutic strategies include hypothermia, glutamate-receptor blockade, immunosuppression and lately treatment aiming at preserving mitochondrial integrity and function. READ MORE

  3. 13. Knee function, knee proprioception and related brain activity following anterior cruciate ligament injury

    Author : Andrew Strong; Charlotte Häger; Eva Tengman; Divya Srinivasan; Eleni Kapreli; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; knee; proprioception; joint position sense; kinematics; injury prevention; sports; functional magnetic resonance imaging; brain; reliability; validity; sjukgymnastik; Physiotherapy; Sports Medicine; idrottsmedicin; rehabiliteringsmedicin; Rehabilitation Medicine;

    Abstract : Background: Injury of the anterior cruciate ligament (ACL) may have negative effects on the short- and long-term function and proprioception of the knee joint. However, existing tests of knee function are often sports-related and less relevant for assessment in the very long term and there remains no ‘gold standard’ test of knee proprioception. READ MORE

  4. 14. Machine learning for identification of brain activity patterns with applications in gentle touch processing

    Author : Malin Björnsdotter Åberg; Göteborgs universitet; []
    Keywords : Somatosensory; Machine learning; Pattern recognition; fMRI; Support vector machines; Neuroscience; Brain; BOLD; Signal processing; Artificial intelligence; Touch; Human; Unmyelinated; Sensory; Affective;

    Abstract : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.

  5. 15. Probing brain microstructure with multidimensional diffusion MRI: Encoding, interpretation, and the role of exchange

    Author : Björn Lampinen; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Diffusion; Human; Brain; Microstructure; Fysicumarkivet A:2021:Lampinen;

    Abstract : Diffusion MRI (dMRI) is a non-invasive probe of human brain microstructure. It is a long-standing promise to use dMRI for ‘in vivo histology’ and estimate tissue quantities. However, this faces several challenges. First, the microstructure models used for dMRI data are based on assumptions that may cause erroneous interpretations. READ MORE
