    Implementing immersive technologies in consumer testing : Liking and Just-About-Right ratings in a laboratory, immersive simulated café and real café

    Context - Engagement - Immersive technology - Just-About-Right ratings - Liking

    Initial research indicates that the use of immersive technologies may improve the predictive validity and reliability of liking scores in consumer testing. However, how immersive technologies impact Just-About-Right ratings is hardly known. Forty-five participants took part in three tasting sessions, each in a different context: 1) laboratory, 2) immersive context simulating a café using audiovisual cues, and 3) real café. Each session, participants tasted four tomato soups varying in salt content preceded by a warm-up sample. Liking, optimal levels of sensory attributes (JAR) and engagement were measured. Results showed that there were no differences in liking or JAR ratings on sensory attributes of the soups across the three contexts. Nevertheless, participants felt more engaged in the real café and simulated café than in the laboratory. These results contribute to a better understanding of how sensory differences as assessed in a laboratory or immersive context relate to sensory differences that consumers would notice when they use the products in real-life.

    cholesteryl ester transfer - systems biology - apoe-asterisk-3-leiden.cetp mice - aggravates atherosclerosis - overweight patients - chinese medicine - weight-reduction - transfer protein - hdl-cholesterol - transgenic mice
    Background: Causes and consequences of the complex changes in lipids occurring in the metabolic syndrome are only partly understood. Several interconnected processes are deteriorating, which implies that multi-target approaches might be more successful than strategies based on a limited number of surrogate markers. Preparations from Chinese Medicine (CM) systems have been handed down with documented clinical features similar as metabolic syndrome, which might help developing new intervention for metabolic syndrome. The progress in systems biology and specific animal models created possibilities to assess the effects of such preparations. Here we report the plasma and liver lipidomics results of the intervention effects of a preparation SUB885C in apolipoprotein E3 Leiden cholesteryl ester transfer protein (ApoE*3Leiden.CETP) mice. SUB885C was developed according to the principles of CM for treatment of metabolic syndrome. The cannabinoid receptor type 1 blocker rimonabant was included as a general control for the evaluation of weight and metabolic responses. Methodology/Principal Findings: ApoE*3Leiden.CETP mice with mild hypercholesterolemia were divided into SUB885C-, rimonabant- and non-treated control groups. SUB885C caused no weight loss, but significantly reduced plasma cholesterol (-49%, p <0.001), CETP levels (-31%, p
    Inactivation of a MAPK-like protein kinase and activation of a MBP kinase in germinating barley embryos

    Germination - Hordeum distichum - Mitogen-activated protein kinase - Myelin basic protein kinase - Rehydration

    We provide evidence for involvement of two different 45 kDa protein kinases in rehydration and germination of barley embryos. In dry embryos, a myelin basic protein (MBP) phosphorylating kinase was detected, which could be immunoprecipitated with an anti-MAPK (mitogen-activated protein kinase) antibody. Rehydration of the embryo induced a decrease in activity of this 45 kDa MAPK-like protein kinase. In addition, activity of a MBP kinase of the same molecular weight was subsequently found to be induced. This second MBP kinase activity could not be immunoprecipitated with the anti-MAPK antibody and was induced only in germinating embryos, not in dormant embryos.
