    • Breaking up prolonged sitting time with walking does not affect appetite or gut hormone concentrations but does induce an energy deficit and suppresses postprandial glycaemia in sedentary adults 

      Bailey, Daniel P.; Broom, David R.; Chrismas, Bryna C.R.; Taylor, Lee; Flynn, Edward; ... more authors ( NRC Research Press , 2016 , Article)
      Background: Breaking up periods of prolonged sitting can negate harmful metabolic effects but the influence on appetite and gut hormones is not understood and is investigated in this study. Methods: Thirteen sedentary (7 ...

    • Chronic probiotic supplementation with or without glutamine does not influence the eHsp72 response to a multi-day ultra-endurance exercise event. 

      Marshall, Hannah; Chrismas, Bryna Catherine Rose; Suckling, Craig Anthony; Roberts, Justin D; Foster, Josh; ... more authors ( NRC Research Press , 2017 , Article)
      Probiotic and glutamine supplementation increases tissue Hsp72, but their influence on extracellular Hsp72 (eHsp72) has not been investigated. The aim of this study was to investigate the effect of chronic probiotic ...

    • Developing common protocols to measure tundra herbivory across spatial scales 

      Barrio, Isabel C; Ehrich, Dorothée; Soininen, Eeva M; Ravolainen, Virve; Bueno, C Guillermo; ... more authors ( NRC Research Press , 2021 , Article)
      Understanding and predicting large-scale ecological responses to global environmental change requires comparative studies across geographic scales with coordinated efforts and standardized methodologies. We designed, applied ...

    • Purification and characterization of an extracellular phenol oxidase from culture filtrates of Pyricularia oryzae 

      Alsubaey, Aisha; Sisler, Hugh D.; Matthews, Benjamin F. ( NRC Research Press , 1996 , Article)
      Extracellular phenol oxidase activity was characterized and compared in Pyricularia oryzae wild-type and albino cell types to determine if this phenol oxidase was responsible for lack of melanization in the albino culture. ...

    • The tundra phenology database: More than two decades of tundra phenology responses to climate change 

      Prevéy, Janet; Elmendorf, Sarah; Bjorkman, Anne; Alatalo, Juha; Ashton, Isabel; ... more authors ( NRC Research Press , 2021 , Article)
      Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established ...

    • Vegetation responses to 26 years of warming at Latnjajaure Field Station, northern Sweden 

      Scharn, Ruud; Brachmann, Cole G.; Patchett, Aurora; Reese, Heather; Bjorkman, Anne; ... more authors ( NRC Research Press , 2021 , Article)
      Climate change is rapidly warming high latitude and high elevation regions influencing plant community composition. Changes in vegetation composition have motivated the coordination of ecological monitoring networks across ...
