  2. 21. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species

    Author : Fredrik Clausen; Lars Hillered; Tiit Mathiesen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic Brain Injury; Reactive oxygen species; Fluid percussion injury; Controlled cortical impact; weight drop injury; Extracellular-signal regulated kinase; apoptosis; free radical scavenging; morphology; functional outcome; Neurovetenskap; Neurology; Neurologi;

    Abstract : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. READ MORE

  5. 23. Oxygen-carrier materials for chemical-looping combustion

    Author : Paul In-Young Cho; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon Dioxide Capture; and Defluidization.; Carbon Formation; Chemical-Looping Combustion; Oxygen Carrier; CO2 Separation;

    Abstract : For combustion with CO2 capture, chemical-looping combustion (CLC) with inherent separation of CO2 is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, a gaseous fuel is oxidized by an oxygen carrier, e.g. READ MORE

  6. 24. Oxygen Carriers Materials for Chemical-Looping Technologies

    Author : Muhammad Qamar Ul Islam Zafar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Natural gas; Reaction kinetics; Oxygen carriers; Chemical-looping reforming; TGA; Chemical-looping combustion; CO2; Metal oxides;

    Abstract : Carbon dioxide is the gas which contributes most to the greenhouse effect. It is released in large quantities from fossil fuel-based power plants around the world. It is generally accepted that a rapid decrease in the emissions of carbon dioxide is needed. READ MORE

  7. 25. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans

    Author : Daniele A. Cardinale; Filip J Larsen; David Bishop; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; OXPHOS; p50mito; mitochondrial oxygen affinity; oxygen extraction; sex difference; hyperoxia; training; muscle metabolism; performance; HIIT; Medicin Teknik; Medicine Technology;

    Abstract : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.
