N1-methylnicotinamide is a signalling molecule produced in skeletal muscle coordinating energy metabolism
Obesity is a major health problem, and although caloric restriction and exercise are successful strategies to lose adipose tissue in obese individuals, a simultaneous decrease in skeletal muscle mass, negatively effects metabolism and muscle function. To deeper understand molecular events occurring in muscle during weight-loss, we measured the expressional change in human skeletal muscle following
How feathered are birds? Environment predicts both the mass and density of body feathers
1. Studies modelling heat transfer of bird plumage design suggest that insulative properties can be attributed to the density and structure of the downy layer, whereas waterproofing is the result of the outer layer, comprised of contour feathers. In this study, we test how habitat and thermal condition affect feather mass and density of body feathers (contour, semiplume and downy feathers) measure1.Studies modelling heat transfer of bird plumage design suggest that insulative properties can be attributed to the density and structure of the downy layer, whereas waterproofing is the result of the outer layer, comprised of contour feathers.

Cognitive medicine - a new approach in health care science
Background: The challenges of today's society call for more knowledge about how to maintain all aspects of cognitive health, such as speed/attention, memory/learning, visuospatial ability, language, executive capacity and social cognition during the life course. Main text: Medical advances have improved treatments of numerous diseases, but the cognitive implications have not been sufficiently addr

From cell death to neuronal regeneration : building a new brain after traumatic brain injury
During the past decade, there has been accumulating evidence of the involvement of passive and active cell death mechanisms in both the clinical setting and in experimental models of traumatic brain injury (TBI). Traditionally, research for a treatment of TBI consists of strategies to prevent cell death using acute pharmacological therapy. However, to date, encouraging experimental work has not be
Lateral fluid percussion brain injury : a 15-year review and evaluation
This article comprehensively reviews the lateral fluid percussion (LFP) model of traumatic brain injury (TBI) in small animal species with particular emphasis on its validity, clinical relevance and reliability. The LFP model, initially described in 1989, has become the most extensively utilized animal model of TBI (to date, 232 PubMed citations), producing both focal and diffuse (mixed) brain inj
Effects of the selective cyclooxygenase-2 inhibitor rofecoxib on cell death following traumatic brain injury in the rat
PURPOSE: Lateral fluid percussion brain injury (FPI) increases cyclooxygenase-2 (COX-2) expression in the cortex and hippocampus. The objective was to investigate whether the selective COX-2 inhibitor rofecoxib (10 mg/kg twice daily) reduces neuronal cell death after FPI in rats, since rofecoxib has been shown to be neuroprotective in other models of CNS injury.METHODS: Rofecoxib (n = 23) or vehic
Evaluation of pharmacological treatment strategies in traumatic brain injury
Traumatic brain injury (TBI) is a devastating disease, predominately affecting young people. Although the prognosis for TBI victims has improved in recent years, many survivors of TBI suffer from emotional, cognitive and motor disturbances and a decreased quality of life. In recent years, there has been a rapid increase in the number of pharmacological targets evaluated in clinically-relevant expe
Energy metabolic changes in the early post-injury period following traumatic brain injury in rats
Impaired cerebral energy metabolism may be a major contributor to the secondary injury cascade that occurs following traumatic brain injury (TBI). To estimate the cortical energy metabolic state following mild and severe controlled cortical contusion (CCC) TBI in rats, ipsi-and contralateral cortical tissues were frozen in situ at 15 and 40 min post-injury and adenylate (ATP, ADP, AMP) levels were
Cerebral glutamine and glutamate levels in relation to compromised energy metabolism : a microdialysis study in subarachnoid hemorrhage patients
Astrocytic glutamate (Glt) uptake keeps brain interstitial Glt levels low. Within the astrocytes Glt is converted to glutamine (Gln), which is released and reconverted to Glt in neurons. The Glt-Gln cycle is energy demanding and impaired energy metabolism has been suggested to cause low interstitial Gln/Glt ratios. Using microdialysis (MD) measurements from visually noninjured cortex in 33 neuroin

Macroscopic modelling of coupled multiphysics in swelling cellulose based materials
Paperboard has been the basis for packaging materials used to aseptically store and protect food and beverages for a long time. To ensure that there are no bacteria that can spoil the product, sterilizing treatments are made. One such treatment is the retorting process, which involves heating to high temperatures in a pressurized environment of water vapor and dry air. The porous nature of paper m
Temporally Dense Ray Tracing
We present a technique for real-time ray tracing with the goal of reaching 240 frames per second or more. The core idea is to trade spatial resolution for faster temporal updates in such a way that the display and human visual system aid in integrating high-quality images. We use a combination of frameless and interleaved rendering concepts together with ideas from temporal antialiasing algorithmsWe present a technique for real-time ray tracing with the goal of reaching 240 frames per second or more.

EDGE: from quiescent to gas-rich to star-forming low-mass dwarf galaxies
We study how star formation is regulated in low-mass field dwarf galaxies (105≤M⋆≤106M⊙), using cosmological high-resolution (3pc) hydrodynamical simulations. Cosmic reionization quenches star formation in all our simulated dwarfs, but three galaxies with final dynamical masses of 3×109M⊙ are subsequently able to replenish their interstellar medium by slowly accreting gas. Two of these galaxie

Developmental Citizenship, Symbolic Landscapes, and Transformation in China and South Korea
Despite glaring differences between South Korean and Chinese societies, South Korea offers an instructive reference point when thinking about developmental citizenship in China. Experiences of mobilization, albeit distinct in each country, inform the sorts of symbols that bring people together for resistance against or compliance with authority. The concept of developmental citizenship, besides dr
Authoritarian Legality after Authoritarianism : Legal Governance of Parties and Elections before and after Democratic Transition in South Korea
The Republic of Korea (ROK) was designed as a Cold War democracy. It started as an electoral regime with formal commitments to democratic values, but institutions designed to keep the state secure also imposed limits on domestic political struggle. From the ROK’s founding in 1948 to the political liberalization of 1987, the political system shifted between orders that might be labeled more democra
