    Companies must redefine their portfolio in such a way that people will perceive it as having added value for their personal lives, says RSM's Professor Cees van Riel, an expert in reputation management – and there's good reason for the world's biggest companies to believe him

    Novel avian-origin influenza A (H7N9) virus attaches to epithelium in both upper and lower respiratory tract of humans

    Influenza A viruses from animal reservoirs have the capacity to adapt to humans and cause influenza pandemics. The occurrence of an influenza pandemic requires efficient virus transmission among humans, which is associated with virus attachment to the upper respiratory tract. Pandemic severity depends on virus ability to cause pneumonia, which is associated with virus attachment to the lower respiratory tract. Recently, a novel avian-origin H7N9 influenza A virus with unknown pandemic potential emerged in humans. We determined the pattern of attachment of two genetically engineered viruses containing the hemagglutinin of either influenza virus A/Shanghai/1/13 or A/Anhui/1/13 to formalin-fixed human respiratory tract tissues using histochemical analysis. Our results show that the emerging H7N9 virus attached moderately or abundantly to both upper and lower respiratory tract, a pattern not seen before for avian influenza A viruses. With the caveat that virus attachment is only the first step in the virus replication cycle, these results suggest that the emerging H7N9 virus has the potential both to transmit efficiently among humans and to cause severe pneumonia

    A data-driven computational model for obesity-driven diabetes onset and remission through weight loss

    Obesity is a major risk factor for the development of type 2 diabetes (T2D), where a sustained weight loss may result in T2D remission in individuals with obesity. To design effective and feasible intervention strategies to prevent or reverse T2D, it is imperative to study the progression of T2D and remission together. Unfortunately, this is not possible through experimental and observational studies. To address this issue, we introduce a data-driven computational model and use human data to investigate the progression of T2D with obesity and remission through weight loss on the same timeline. We identify thresholds for the emergence of T2D and necessary conditions for remission. We explain why remission is only possible within a window of opportunity and the way that window depends on the progression history of T2D, individual’s metabolic state, and calorie restrictions. These findings can help to optimize therapeutic intervention strategies for T2D prevention or treatment

    In Silico Analysis Identifies Intestinal Transit as a Key Determinant of Systemic Bile Acid Metabolism

    Bile acids fulfill a variety of metabolic functions including regulation of glucose and lipid metabolism. Since changes of bile acid metabolism accompany obesity, Type 2 Diabetes Mellitus and bariatric surgery, there is great interest in their role in metabolic health. Here, we developed a mathematical model of systemic bile acid metabolism, and subsequently performed in silico analyses to gain quantitative insight into the factors determining plasma bile acid measurements. Intestinal transit was found to have a surprisingly central role in plasma bile acid appearance, as was evidenced by both the necessity of detailed intestinal transit functions for a physiological description of bile acid metabolism as well as the importance of the intestinal transit parameters in determining plasma measurements. The central role of intestinal transit is further highlighted by the dependency of the early phase of the dynamic response of plasma bile acids after a meal to intestinal propulsion

    Nieuw stelsel agrarisch natuurbeheer : criteria voor leefgebieden en beheertypen

    Get PDF
    In het nieuwe stelsel Agrarisch Natuur en Landschapsbeheer (ANLb-2016) worden vier agrarisch leefgebieden onderscheiden en daarbinnen 10 beheertypen. Deze eenheden vormen de basiseenheden van het stelsel waarvan het beheer in zogenaamde gebiedsplannen zal worden uitgewerkt. Voor deze eenheden zijn op basis van ecologische kennis kwalitatieve en kwantitatieve criteria uitgewerkt. De criteria zijn bedoeld als hulpmiddel voor het opstellen en beoordelen van gebiedsplannen. De soortenfiches, soortenmaatregelen en de eerder genoemde leefgebiedenbeschrijving, opgesteld door Wouter van Heusden, zijn gebruikt als uitgangspunt
