  2. 1. Effect of timing training in golf and soccer players : skill, movement organization, and brain activity

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Motor timing; rhythmicity; timing training; golf shot; golf swing; kinematics; precision; variability; coordination; movement dynamics; soccer; fMRI; mirror neurons; action observation; cerebellum; perception - action.; Psychology; psykologi;

    Abstract : Background Although trainers and athletes consider ‘good timing skills’ to be critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Thus, assuming that all motor performances are mediated by an internal timing mechanism, enhanced motor timing is expected to have positive effects on both planning and execution of movement performance, and consequently on complex sports actions as golf or soccer.

  4. 2. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster

    Author : Hao Cao; Helgi B. Schiöth; Michael J. Williams; Jan Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xenobiotics; metabolism; insulin signalling; circadian rhythm; carcinogen; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Abstract : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.

  5. 3. Nutrient-regulated skeletal muscle metabolism and circadian clock

    Author : Laura Sardon Puig; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The prevalence of obesity has tripled in the last four decades, becoming a major risk for the development of cardiometabolic diseases such as type 2 diabetes. Obesity is associated with pathological storage of lipids in skeletal muscle, causing a major disturbance in metabolism. READ MORE

  6. 4. Voltage sensor movements in shaker and HCN channels

    Author : Roope Männikkö; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Voltage-gated ion channels are crucial for electrical signaling in living organisms. They are composed of four similar subunits with six transmembrane α-helices, S1-S6. Each subunit contains a voltage-sensing domain, S1-S4, and an ion-conducting pore domain, S5-S6. READ MORE

  7. 5. Inducible and constitutive modes of gene regulation by the dioxin receptor and Arnt

    Author : Camilla Antonsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Heterodimeric complexes between the basic helix-loop-helix (bHLH)/PAS (Per-Arnt-Sim) transcription factors, dioxin receptor and Arnt, are involved in mediating cellular responses to 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin). The unliganded dioxin receptor is found in the cytoplasm complexed with the 90-kDa heat shock protein hsp90, in a latent inactive (non-DNA binding) configuration. READ MORE
