    Abstract Background: The dysfunction of energy metabolism in white adipose tissue (WAT) induces adiposity. Obesogenic diets that are high in saturated fat disturb nutrient metabolism in adipocytes. This study investigated the effect of an isocaloric high-fat diet without the confounding effects of weight gain on the gene expression of fatty acid and carbohydrate transport and metabolism and its genetic inheritance in subcutaneous (s.c.) WAT of healthy human twins.
    Methods: Forty-six healthy pairs of twins (34 monozygotic, 12 dizygotic) received an isocaloric carbohydrate-rich diet (55% carbohydrates, 30% fat, 15% protein; LF) for 6 weeks followed by an isocaloric diet rich in saturated fat (40% carbohydrates, 45% fat, 15% protein; HF) for another 6 weeks.
    Results: Gene expression analysis of s.c. WAT revealed that fatty acid transport was reduced after one week of the HF diet, which persisted throughout the study and was not inherited, whereas intracellular metabolism was decreased after six weeks and inherited. An increased inherited gene expression of fructose transport was observed after one and six weeks, potentially leading to increased de novo lipogenesis.
    Conclusion: An isocaloric dietary increase of fat induced a tightly orchestrated, partially inherited network of genes responsible for fatty acid and carbohydrate transport and metabolism in human s.c. WAT.

    Abstract Objective: To describe the instruments used by nurses for the management of care in face of the demands of the emergency hospital service.
    Method: This is a qualitative study, with triangulation of data from interviews, focus groups, and documents, conducted with nurses from an Emergency Hospital Service in a state in southern Brazil. Data were subjected to thematic content analysis.
    Results: Seventeen nurses participated in the study. The categories emerging from this study were view of the whole picture, definition of priorities, and physical instruments. These instruments are used by nurses to manage multiple tasks and provide adequate care to patients with different levels of complexity, in the face of an intense and unpredictable work process due to the constant demand for care.
    Conclusion: The instruments used by nurses in their work process are mainly skills and attitudes developed as a coping strategy at an intense and complex work environment.

    Abstract Close-range 3D sensors based on the structured light principle have a constrained measuring range due to their depth of field (DOF). Focus stacking is a method to extend the DOF. The additional time to change the focus is a drawback in high-speed measurements. In our research, the method of chromatic focus stacking was applied to a high-speed 3D sensor with 180 fps frame rate. The extended DOF was evaluated by the distance-dependent 3D resolution derived from the 3D-MTF of a tilted edge. The conventional DOF of 14 mm was extended to 21 mm by stacking two foci at 455 and 520 nm wavelength. The 3D sensor allowed shape measurements with extended DOF within 44 ms.

    Abstract 1. Indirect induced plant defence via emission of herbivore‐induced plant volatiles (HIPV) to recruit natural enemies of herbivores is a ubiquitous phenomenon, but whether and how emission of above‐ground HIPVs is adaptively modulated by below‐ground mutualistic micro‐organisms is unknown. 2. We investigated the effects of the mycorrhizal fungus Glomus mosseae on chemical composition of HIPVs emitted by bean plants Phaseolus vulgaris attacked by spider mites, Tetranychus urticae, using proton‐transfer mass spectrometry, and attraction of the spider mites’ natural enemy, the predatory mite Phytoseiulus persimilis, to these HIPVs using a Y‐tube olfactometer. 3. Mycorrhiza significantly changed the HIPV composition. Most notably, it increased the emission of β‐ocimene and β‐caryophyllene, two compounds synthesized de novo upon spider mite attack. The constitutively emitted methyl salicylate was increased by spider mite infestation but decreased by mycorrhiza. 4. The predators responded strongly to HIPVs emitted by plants infested for 6 days and preferred HIPVs of mycorrhizal plants to those of non‐mycorrhizal plants. In contrast, they were less responsive and indiscriminative to mycorrhization when exposed to volatiles emitted by non‐infested plants and plants infested by spider mites for 1 or 3 days. 5. Our study provides a key example of an adaptive indirect HIPV‐mediated interaction of a below‐ground micro‐organism with an above‐ground carnivore.

    Abstract Most terrestrial plants are associated with arbuscular mycorrhizal fungi but research on the effects of arbuscular mycorrhizal symbiosis on aboveground plant-associated organisms is scarcely expanded to tri-trophic systems. The arbuscular mycorrhizal fungus Glomus mosseae Nicol. & Gerd. enhances fitness of the two-spotted spider mite Tetranychus urticae Koch and its natural enemy, the predatory mite Phytoseiulus persimilis Athias-Henriot, via changes in host plant and prey quality, respectively. In the present study, it is hypothesized that gravid P. persimilis are able to recognize arbuscular mycorrhiza-enhanced prey quality and behave accordingly. In two experiments, on leaf arenas and in cages, P. persimilis is given a choice between prey patches deriving from mycorrhizal and non-mycorrhizal bean plants (Phaseolus vulgaris L.) as feeding and oviposition sites. The use of cages allows the manipulation of distinct patch components acting as possible cues to guide predator foraging and oviposition behaviours, such as eggs produced and traces (webbing and faeces) left by the spider mite females. Both experiments show that P. persimilis preferentially resides close to prey fed on mycorrhizal plants. The cage experiment reveals that P. persimilis uses direct prey-related cues, mainly derived from eggs, to discern prey quality and preferentially oviposits close to prey from mycorrhizal plants. This is the first study to document that predators recognize arbuscular mycorrhiza-induced changes in herbivorous prey quality via direct prey-related cues.

    Abstract Research on trophic cascades in terrestrial ecosystems has only recently revealed that root-associated organisms interact with organisms living on aboveground plant parts. Arbuscular mycorrhizal (AM) symbiosis is a ubiquitous phenomenon, yet studies on its effect on aboveground natural enemies of herbivores are scarce and mainly deal with plant-mediated rather than herbivore-mediated interactions. Here, we studied herbivore-mediated effects of AM symbiosis on an acarine predator. We measured life history characteristics and population growth rates of Phytoseiulus persimilis preying on two-spotted spider mites, Tetranychus urticae, which were feeding on bean plants colonized or not colonized by the AM fungus Glomus mosseae. All major life history characteristics of P. persimilis, foremost oviposition rate, minimum prey requirements needed to reach adulthood, and developmental time, were positively affected by AM colonization of the host plant of their prey, together resulting in enhanced population growth rates of the predators. Hence, we hypothesize that a bottom-up trophic cascade may counteract the apparent negative effects of mycorrhizal symbiosis when promoting herbivory by promoting the predation of herbivores due to improved prey quality. We argue that this pathway may be involved in stabilizing plant-mycorrhizal symbiosis in ecosystems over time.

    Abstract 1. Arbuscular mycorrhiza (AM), the association of AM fungi and plant roots, may alter morphological and physiological attributes of aboveground plant parts and thereby influence plant‐associated organisms such as herbivores and their natural enemies, predators and parasitoids. 2. The interactions between AM and the players of aboveground tri‐trophic systems have mainly been considered in isolation from each other. The effects of AM on aboveground herbivore–carnivore population dynamics and the consequences to plant fitness are unknown. 3. We explored AM‐induced compensatory mechanisms for AM‐promoted proliferation of the herbivorous spider mite, Tetranychus urticae Koch, on whole bean plants, Phaseolus vulgaris L. Vegetative and reproductive plant growth, AM fungal colonisation levels, and mite densities were assessed on spider mite‐infested plants colonised or not by the AM fungus Glomus mosseae Nicol. & Gerd, and harbouring the natural enemy of the spider mites, the predatory mite Phytoseiulus persimilis Anthias‐Henriot or not. 4. AM symbiosis modulated the aboveground tri‐trophic system to the fitness benefit of the plant. AM‐increased plant productivity outweighed the fitness decrease due to AM‐promoted herbivory: at similar vegetative growth, mycorrhizal plants produced more seeds than non‐mycorrhizal plants. 5. AM‐increased spider mite population levels were compensated for by enhanced population growth of the predators and increased plant tolerance to herbivory. 6. AM‐enhanced predator performance looped back to the AM fungus and stabilised its root colonisation levels, providing the first experimental evidence of a mutually beneficial interaction between AM and an aboveground third trophic level natural enemy.
