  2. 1. Aerobic fitness and healthy brain aging : cognition, brain structure, and dopamine

    Author : Lars Jonasson; Carl-Johan Boraxbekk; Katrine Riklund; Emrah Düzel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aerobic exercise; VO2; working memory; executive function; freesurfer; striatum; dopamine; D2-receptors; [11C]raclopride;

    Abstract : Background: Performing aerobic exercise and maintaining high levels of aerobic fitness may have positive effects on both brain structure and function in older adults. Despite decades of research however, there is still a rather poor understanding of the neurocognitive mechanisms explaining the positive effects of aerobic exercise on cognition. READ MORE

  4. 2. Skeletal Muscle Mass & Function in Older Women : Health-Enhancing Influences of Combined Resistance Exercise & Diet

    Author : Emelie Strandberg; Fawzi Kadi; Elodie Ponsot; Carl-Johan Sundberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Healthy ageing; Chronic inflammation; C-reactive protein; Omega-3 fatty acids; Resistance training; Physical function;

    Abstract : Ageing is accompanied by a progressive decline in skeletal muscle mass and strength which may lead to impaired ability to perform activities of daily living in older adults. Although the exact cause of the gradual decline in muscle mass is unknown, identifying efficient strategies aiming to prevent age-related loss of muscle mass and strength is important in order to promote healthy ageing.

  5. 3. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Abstract : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. READ MORE

  6. 4. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Author : Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

    Abstract : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. READ MORE

  7. 5. Function follows Form : Trait-based approaches to climate change effects on wetland vegetation and functioning

    Author : Helen Moor; Jon Norberg; Andrew Gonzalez; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Functional traits; Plant community ecology; Trait distributions; Wetlands; Ecosystem functioning; Ecosystem Services; Climate change; Dispersal; Metacommunity modelling; naturresurshushållning; Natural Resources Management;

    Abstract : Climate change and habitat fragmentation are altering the structure and functioning of plant communities world-wide. Understanding how, why and with what consequences are major challenges of ecology today. Trait-based approaches focus on functional rather than taxonomic identity to facilitate process-based explanation and prediction. READ MORE
