Abstract

IF 1.710; International audience; Fungal respiratory colonization of cystic fibrosis (CF) patients emerges as a new concern; however, the heterogeneity of mycological protocols limits investigations. We first aimed at setting up an efficient standardized protocol for mycological analysis of CF sputa that was assessed during a prospective, multicenter study: “MucoFong” program (PHRC-06/1902). Sputa from 243 CF patients from seven centers in France were collected over a 15-month period and submitted to a standardized protocol based on 6 semi-selective media. After mucolytic pretreatment, sputa were plated in parallel on cycloheximide-enriched (ACT37), erythritol-enriched (ERY37), benomyl dichloran–rose bengal (BENO37) and chromogenic (CAN37) media incubated at 37 °C and on Sabouraud–chloramphenicol (SAB27) and erythritol-enriched (ERY27) media incubated at 20–27 °C. Each plate was checked twice a week during 3 weeks. Fungi were conventionally identified; time for detection of fungal growth was noted for each species. Fungal prevalences and media performances were assessed; an optimal combination of media was determined using the Chi-squared automatic interaction detector method. At least one fungal species was isolated from 81% of sputa. Candida albicans was the most prevalent species (58.8%), followed by Aspergillus fumigatus (35.4%). Cultivation on CAN37, SAB27, ACT37 and ERY27 during 16 days provided an optimal combination, detecting C. albicans, A. fumigatus, Scedosporium apiospermum complex and Exophiala spp. with sensitivities of 96.5, 98.8, 100 and 100%. Combination of these four culture media is recommended to ensure the growth of key fungal pathogens in CF respiratory specimens. The use of such consensual protocol is of major interest for merging results from future epidemiological studies.

Abstract

Chapter 13 10th International Conference, MTSR 2016, Göttingen, Germany, November 22-25, 2016, Proceedings; International audience; This paper focuses on the knowledge representation task for an interdisciplinary project called Delicious concerning the production and transformation processes in food science. The originality of this project is to combine data from different disciplines like food composition, food structure, sensorial perception and nutrition. Available data sets are described using different vocabularies and are stored in different formats. Therefore there is a need to define an ontology, called PO2PO2 (Process and Observation Ontology), as a common and standardized vocabulary for this project. The scenario 6 of the NeON methodology was used for building PO2PO2 and the core component is implemented in OWL. By making use of PO2PO2 , data from the project were structured and an use case is presented here. PO2PO2 aims to play a key role as the representation layer of the querying and simulation systems of Delicious project.

Abstract

In order to maintain healthy colonies, termite workers dispose of the cadavers of dead nest mates by cannibalism, burial, or necrophoresis. However, when multiple reproductives found a new colony by pleometrosis, there are no worker castes at the early stages of the foundation to eliminate or isolate the corpses. In this study, we showed that in young pleometrotic colonies, reproductives of Pseudacanthotermes spiniger had the ability to perform this task. Because of the claustral conditions, and the potential inability of the dealates to feed on their own, their behaviour was restricted to the burial of the cadaver within the initial chamber. This burial behaviour, previously not reported in the reproductive caste of termites, appeared to be induced by chemical signals released by the corpses during decomposition, among which various fatty acids, indole and phenol were the most active. The burial finally resulted in the physical isolation of corpses, thus reducing the chances for opportunistic pathogens to spread among the rest of the individuals.

Papier publié également dans : Proceedings en ligne de American Institute of Physics http://proceedings.aip.org/dbt/dbt.jsp?KEY=APCPCS&Volume=1137&Issue=1 (RN 2508; Sensory perception of the flavor release during the eating of a food piece is highly dependent upon mouth parameters. Major limitations have been reported during in vivo flavor release studies, such as marked intra- and inter-individual variability. To overcome these limitations, a chewing simulator has been developed to mimic the human mastication of food samples. The device faithfully reproduces most of the functions of the human mouth. The active cell comprises several mobile parts that can accurately reproduce shear and compression strengths and tongue functions in real-time, according to data previously collected in vivo. The mechanical functionalities of the system were validated using peanuts, with a fair agreement with the human data. Flavor release can be monitored on-line using either API-MS or chemical sensors, or off-line using HPLC for non-volatile compounds. Couplings to API-MS detectors have shown differences in the kinetics of flavor release, as a function of the food sample composition. Data were also collected for the analysis of taste compounds released during the human chewing but are not available yet for the chewing simulator.

Abstract

International audience; The evaluation of the temporality of the sensory perception in food products is mainly assessed using the time–intensity (TI) methodology. This approach is useful for studying the temporal aspects of the perception of a given sensory attribute in a product. When TI is used for several attributes, it quickly becomes very time-consuming because one run is needed by attribute. A new method of sensory evaluation, called Temporal Dominance of Sensations (TDS), was proposed by the authors a few years ago [Pineau, N., Cordelle, S., & Schlich, P. (2003a). Temporal Dominance of Sensations: A new technique to record several sensory attributes simultaneously over time. In 5th Pangborn symposium (p. 121). July 20–24]. It makes possible to collect temporal data during one single evaluation for up to 10 attributes on complex food products. The method consists in presenting the entire set of attributes to the panellist on the computer screen. Along the tasting of one product, the panellist has to wonder what the dominant sensory perception is and to select and score the corresponding attribute. Each time the panellist thinks the dominant sensory perception has changed, either in intensity or in quality, he/she has to score the new perception. For each run, this method enables to collect a sequence of sensory attributes (and their respective scoring) quoted at different times along the tasting. Based on one study on five dairy products, this paper explains how to describe the temporality of the sensations in a product thanks to the TDS curves. TI was also performed on the same products to compare the two methodologies. TDS and TI results exhibit close patterns of sensations but TDS is found to better enhance the sequence of the sensations over time.

Abstract

International audience; In adult mammals, the processing of complex odor mixtures is elemental or configural. Here, we challenged these processes in newborn rabbits, in evaluating their perception of a binary odor mixture for which perceptual blending occurs in humans. This model of newborn animal was interesting since general questions remain on how odor cues are processed in immature organisms, and since rabbit pups present abilities of rapid odor learning. In the present study, we first demonstrated (Exp. 1) that rabbit pups rapidly acquired the odor of the binary mixture through associative conditioning (when the mammary pheromone was used as unconditioned stimulus). Then, we compared how they responded to the mixture, its components and the mammary pheromone, after they had learned the mixture or one of its constituents. After they had learned the odor of the mixture, they responded to its odor and the odor of its constituents (Exp. 2). However, after they had learned one constituent's odor, they responded to this odor but not to the mixture's odor (Exp. 3). The response to the mixture appeared nevertheless when pups successively acquired the odor of the two components (Exp. 4). Therefore, both elemental and configural processing of the mixture seem to be displayed by rabbit pups, suggesting that neonatal perception of a simple odor mixture may involve more than the perception of its constituents.

Abstract

SummaryWe here identify and characterize an extracellular modulator of Hedgehog signaling in Drosophila, Shifted. Shifted is required for high levels of long-range signaling in the developing wing imaginal disc. Surprisingly, shifted encodes the only Drosophila ortholog of the secreted vertebrate protein Wnt Inhibitory Factor-1 (WIF-1), whose known role is to bind to extracellular Wnts and inhibit their activity. However, Shifted does not regulate Hedgehog signaling by affecting Wingless or Wnt signaling. We show instead that Shifted is a secreted protein that acts over a long distance and is required for the normal accumulation of Hh protein and its movement in the wing. Our data further indicate that Shf interacts with Hh and the heparan sulfate proteoglycans. Therefore, we propose that Shf stabilizes the interaction between Hh and the proteoglycans, an unexpected role for a member of the WIF-1 family.

Abstract

The development of the Drosophila wing is a classical model for studying the genetic control of tissue size, shape and patterning. A detailed picture of how positional information is interpreted by cells in the imaginal disc and translated into the adult wing vein pattern has recently emerged. It highlights the central role of dose-dependent activation of distinct cell transcription programs in response to the Hedgehog (Hh) and Decapentaplegic (Dpp) morphogens, as well as an early role of Notch signalling, in connecting the positioning of vein primordia and vein differentiation proper. The biochemical basis of the cross-talk that operates between these different signalling pathways is less well understood. New strategies made possible by the genome sequencing of several insect models should provide an important complement to the knowledge obtained from >60 years of genetic studies.

Abstract

The Drosophila wing is a classical model for studying the generation of developmental patterns. Previous studies have suggested that vein primordia form at boundaries between discrete sectors of gene expression along the antero-posterior (A/P) axis in the larval wing imaginal disc. Observation that the vein marker rhomboid (rho) is expressed at the centre of wider vein-competent domains led to propose that narrow vein primordia form first, and produce secondary short-range signals activating provein genes in neighbouring cells (see Curr. Opin. Genet. Dev. 10 (2000) 393). Here, we examined how the central L3 and L4 veins are positioned relative to the limits of expression of Collier (Col), a dose-dependent Hedgehog (Hh) target activated in the wing A/P organiser. We found that rho expression is first activated in broad domains adjacent to Col-expressing cells and secondarily restricted to the centre of these domains. This restriction which depends upon Notch (N) signaling sets the L3 and L4 vein primordia off the boundaries of Col expression. N activity is also required to fix the anterior limit of Col expression by locally antagonising Hh activation, thus precisely positioning the L3 vein primordium relative to the A/P compartment boundary. Experiments using Nts mutants further indicated that these two activities of N could be temporally uncoupled. Together, these observations highlight new roles of N in topologically linking the position of veins to prepattern gene expression.

Abstract

We present a molecular dynamics (MD) study on the structure of self-assembled monolayers (SAM) of alkylthiolates on various metal surfaces, with especial attention to Au(111) and Ag(111). Variations in the structure of these SAMs as a function of temperature and alkyl-chain length are systematically investigated. The MD simulations are performed by using a recently developed force field based on second-order Møller−Plesset perturbation theory calculations. Good agreement between the present results and the existing experimental data is found on Au(111). On Ag(111) the comparison between theory and experiment is also satisfactory for alkylthiolates with no more than 14 carbon atoms. The dependences of the average tilt angle of SAMs on temperature and chain length are easily understood by means of a simple single-chain model. Fil: Wang, Y.. Universidad Autónoma de Madrid; España.

Abstract

International audience; Using a time-resolved optical interferometric technique, we investigate the ultrafast primary events following the interaction of an ultrashort laser pulse with pure water in the TW/cm2 regime. Because our method is sensitive to the quasi-instantaneous electron energy level position, we demonstrate that in contrast to the well-known low-intensity regime, where the free electrons are instantaneously captured by pre-existing traps, in this new regime of excitation, free electrons are clearly observed, exhibiting a substantial contribution in the near IR. The delayed localization is attributed to the saturation of pre-existing cavities in the liquid by the large number of the excited electron states created.

Abstract

Consumers’ food decisions are based on the information they receive and on their own individual characteristics. This paper is based on an experiment using experimental economics and sensory evaluation to measure individual characteristics of participants and to analyze the impact of nutritional information relative to orange juice. The aim is to explore the potential link between specific characteristics (risk aversion, time preference) and the reactions of consumers to nutritional information. The results show that participants react significantly to this information supplied, positively for the pure orange juice and a negatively for orange nectars. In addition, “risk averse” individuals appear more sensitive to information that “risk neutral” ones. Similarly, individuals with a preference for the future show sharper and more stable responses to information about the products than those who prefer the present., Les consommateurs prennent leurs décisions alimentaires en fonction des informations qu’ils reçoivent et de leurs caractéristiques individuelles. Dans le cadre d’une expérience associant économie expérimentale et évaluation sensorielle, nous mettons en parallèle l’évaluation d’informations nutritionnelles relatives aux jus d’orange et la mesure de caractéristiques individuelles des participants. L’objectif est d’explorer le lien potentiel entre des caractéristiques rarement mesurées (aversion au risque, préférence pour le présent) et les réactions des consommateurs aux informations nutritionnelles. Les résultats montrent que les participants réagissent significativement aux informations nutritionnelles qui leur sont fournies, de façon positive pour les purs jus d’orange et de façon négative pour les nectars d’orange. Par ailleurs, les individus « averse au risque » réagissent plus à l’information que les individus « neutre au risque ». De même les individus ayant une préférence pour le futur réagissent de façon plus nette et plus stable à l’information sur les produits que ceux préférant le présent.

Abstract

International audience; We report the fabrication and characterization of tellurite TeO(2)-ZnO-Na(2)O (TZN) microstructured suspended core optical fibers (MOFs). These fibers are designed for infrared supercontinuum generation with zero dispersion wavelength (ZDW) at 1.451 mu m. The measured losses at this wavelength are approximately 6 dB/m for a MOF with a 2.2 mu m diameter core. The effective area of a particular fiber is 3.5 mu m(2) and the nonlinear coefficient is calculated to be 437 W(-1)km(-1). By pumping a 20 cm long fiber at 1.56 mu m with a sub-nj femtosecond laser source, we generate a supercontinuum (SC) spanning over 800 nm in the 1-2 mu m wavelength range.

Abstract

Purpose: Neuronal tissues such as the retina contain high amounts of particular phospholipids named “ether-lipids”. Since abnormal blood levels of ether-lipids have been associated with several neurological disorders, we wanted to check whether ether-lipid levels were modified and associated with the severity of POAG. Methods: Blood samples were collected from 41 healthy subjects and 64 POAG patients. Following lipid extraction from erythrocytes, total phospholipids including ether-lipids were isolated using silica cartridges. The fatty acid profile of phospholipids was determined using capillary column gas chromatography (GC). The individual molecular species of phospholipids and ether-lipids were quantified by tandem liquid chromatography-mass spectrometry. Results: The levels of ether-lipids were significantly decreased in glaucoma patients and especially the choline ether-lipid sub-class. The Mean Deviation (MD) value from Humphrey perimetry was negatively correlated to erythrocyte levels of total choline ether-lipids (r²=0.99). The linear regression model predicted that total choline ether-lipid levels started to decrease about 20 years prior to clinical symptoms. Conclusions: Although the mechanisms responsible for the reduction of erythrocyte levels of ether-lipids in POAG patients remains unclear, the known functions of ether-lipids in the protection against oxidative stress make these results very consistent with the pathogenesis of glaucoma.

Abstract

The trail-following pheromone and sex pheromones were investigated in the Indomalayan termite Hodotermopsis sjoestedti belonging to the new family Archotermopsidae. Gas chromatography coupled to mass spectrometry (GC-MS) after solid phase microextraction (SPME) of the sternal gland secretion of pseudergates and trail-following bioassays demonstrated that the trailfollowing pheromone of H. sjoestedti was syn-4,6-dimethylundecan-1-ol, a new chemical structure for termite pheromones. GC-MS after SPME of the sternal gland secretion of alates also allowed the identification of sex-specific compounds. In female alates, the major sex-specific compound was identified as (5E)-2,6,10-trimethylundeca-5,9-dienal, a compound previously identified as the female sex pheromone of the termite Zootermopsis nevadensis. In male alates, the major sex-specific compound was identified as syn-4,6-dimethylundecanal, a homolog of syn-4,6-dimethyldodecanal, which has previously been confirmed as the male sex pheromone of Z. nevadensis. The presence of sex-specific compounds in alates of H. sjoestedti strongly suggests for this termite the presence of sex-specific pairing pheromones which were only known until now in Z. nevadensis. Our results showed therefore a close chemical relationship between the pheromones of the taxa Hodotermopsis and Zootermopsis and, in contrast, a clear difference with the taxa Stolotermes and Porotermes, which is in total agreement with the recent creation of the families Archotermopsidae and Stolotermitidae as a substitute for the former family Termopsidae.

Abstract

author can archive publisher's version/PDF (embargo 12 mois); Uptake, retention and release of 5 selected odorants (benzaldehyde, 2-methylpyrazine, 2-isobutyl-3-methoxypyrazine, 2-isobutylthiazole, and 2,4,5-trimethylthiazole) by recombinant rat odor-binding protein 3 (rat-OBP3) were measured in a model system under nonequilibrium conditions. Gaseous odorants were introduced into a 100 mm section of a polar deactivated capillary in which aqueous rat-OBP3 films were formed to mimic the olfactory epithelium (OE), and the change in the gas-phase concentration of the outflow gas was monitored in real time using atmospheric pressure chemical ionization-mass spectrometry (APCI-MS). The 5 odorants were chosen because they exhibited a broad range of dissociation constants with rat-OBP3 and because they were amenable to detection by on-line APCI-MS. All 5 odorants were quantitatively bound by rat-OBP3, which resulted in an effective concentration of the odorants in the aqueous layer (about 50 000-fold). Odorant release from the rat-OBP3-odorant complex into the gas phase showed that odorant release was governed by the dissociation constant of the complex and the flow rate of odorant-free air. When 2 odorants were introduced into the system, odorant uptake and release were influenced by the method of introduction and their relative affinities for the protein. Because rat-OBP3 exhibits typical odorant-binding characteristics, the results not only provide fundamental information on the kinetics of odorant mass transfer induced by the presence of OBPs in the olfactory mucus layer but also support the possibility that vertebrate OBPs may facilitate the accumulation of odorants in the OE.

Abstract

The aim of this study was to investigate the effect of oxidoreduction potential (Eh) on the biosynthesis of aroma compounds by lactic acid bacteria in non-fat yogurt. The study was done with yogurts fermented by Lactobacillus bulgaricus and Streptococcus thermophilus. The Eh was modified by the application of different gaseous conditions (air, nitrogen, and nitrogen/hydrogen). Acetaldehyde, dimethyl sulfide, diacetyl, and pentane-2,3-dione, as the major endogenous odorant compounds of yogurt, were chosen as tracers for the biosynthesis of aroma compounds by lactic acid bacteria. Oxidative conditions favored the production of acetaldehyde, dimethyl sulfide, and diketones (diacetyl and pentane-2,3-dione). The Eh of the medium influences aroma production in yogurt by modifying the metabolic pathways of Lb. bulgaricus and Strep. thermophilus. The use of Eh as a control parameter during yogurt production could permit the control of aroma formation.

Oxysterols are assumed to play important roles in age-related macular degeneration, a major cause of blindness. So we characterized the cytotoxic, oxidative, inflammatory, and angiogenic activities of oxysterols (7β-hydroxycholesterol (7β-OH), 7-ketocholesterol (7KC), 25-hydroxycholesterol (25-OH)) in human retinal ARPE-19 cells, and evaluated the protective effects of resveratrol (Rsv: 1 μM), a polyphenol from red wine.ARPE-19 cells were treated with 7β-OH, 7KC, or 25-OH (5-40 μg/mL; 24-48 h) without or with Rsv. Cell viability was determined using trypan blue and the MTT assay. Cell death was characterized by electron microscopy and in situ detection of activated caspases with fluorochrome-labeled inhibitors of caspases. Reactive oxygen species (ROS) production was measured with hydroethidine. ELISA methods and a cytometric bead assay were used to quantify cytokines involved in inflammation (IL-8, IL-1β, IL-6, IL-10, IL-12p70, TNF-α, MCP-1) and VEGF.7β-OH and 7KC triggered a caspase-independent cell death process associated with the presence of multilamellar cytoplasmic structures evocating phospholipidosis, increased ROS production, and IL-8 secretion. 7β-OH enhanced VEGF secretion. No cytotoxic effects were identified with 25-OH, which highly stimulated ROS production, MCP-1, and VEGF secretion. With oxysterols, no IL-10, TNF-α, and IL-12p70 secretion were detected. 25-OH induced IL-8 secretion through the MEK/ERK½ signaling pathway, and Rsv showed cytoprotective activities and inhibited VEGF secretion.7β-OH, 7KC, and 25-OH have cytotoxic, oxidative, inflammatory, and/or angiogenic activities on ARPE-19 cells. As Rsv has some protective effects against oxysterol-induced cell death and VEGF secretion it could be valuable in ARMD treatment.

Abstract

We have measured the effect of rat odorant-binding protein 1 on the rates of ligand uptake and liquid-to-air transfer rates with a set of defined odorous compounds. Comparison of observed rate constants (k(obs)) with data simulated over a wide range of different kinetic and thermodynamic regimes shows that the data do not agree with the previously held view of a slow off-rate regime (k(off)

Abstract

International audience; BACKGROUND: Acute partial sleep deprivation increases plasma concentrations of ghrelin and decreases those of leptin. OBJECTIVE: The objective was to observe modifications in energy intake and physical activity after acute partial sleep deprivation in healthy men. DESIGN: Twelve men [age: 22 +/- 3 y; body mass index (in kg/m(2)): 22.30 +/- 1.83] completed a randomized 2-condition crossover study. During the first night of each 48-h session, subjects had either approximately 8 h (from midnight to 0800) or approximately 4 h (from 0200 to 0600) of sleep. All foods consumed subsequently (jam on buttered toast for breakfast, buffet for lunch, and a free menu for dinner) were eaten ad libitum. Physical activity was recorded by an actimeter. Feelings of hunger, perceived pleasantness of the foods, desire to eat some foods, and sensation of sleepiness were also evaluated. RESULTS: In comparison with the 8-h sleep session, subjects consumed 559 +/- 617 kcal (ie, 22%) more energy on the day after sleep restriction (P < 0.01), and preprandial hunger was higher before breakfast (P < 0.001) and dinner (P < 0.05). No change in the perceived pleasantness of the foods or in the desire to eat the foods was observed. Physical activity from 1215 to 2015 was higher after sleep restriction than after 8 h of sleep (P < 0.01), even though the sensation of sleepiness was more marked (P < 0.01). CONCLUSIONS: One night of reduced sleep subsequently increased food intake and, to a lesser extent, estimated physical activity-related energy expenditure in healthy men. These experimental results, if confirmed by long-term energy balance measurements, suggest that sleep restriction could be a factor that promotes obesity. This trial was registered at clinicaltrials.gov as NCT00986492.

Abstract

International audience; INTRODUCTION: The aim of this study was to evaluate the impact of the 11th version of the National Health System's Activity-Based Financing on the income of a University Hospital department for palpebral, lacrimal, and orbital surgeries. PATIENTS AND METHODS: The number of such surgeries in 2008 was based on the Medicalization Program of the Information System. Using the 11th version of the Activity-Based Financing for Diagnosis-Related Groups, we compared the income in both inpatient and outpatient settings. RESULTS: Two hundred and forty-eight patients undergoing palpebral, lacrimal, or orbital surgery between January and December 2008 were included, with 87% treated on an outpatient basis. The lower reimbursement for outpatient surgery resulted in a loss of 184,500 euros (79%) for our department compared to the inpatient procedure. DISCUSSION: With rigorous organization, ambulatory surgery is feasible for palpebral, lacrimal, and orbital surgery. Nonetheless, with department incomes related to activity, ambulatory care seems financially disadvantageous. Many departments are trying to develop an ambulatory structure, but the need to balance their budget requires improved coherence.

Abstract

/WOS: 000285178000010; International audience; Describing the taste of water is a challenge since drinking water is supposed to have almost no taste. In this study, different classical sensory methodologies have been applied in order to assess sensory characteristics of water and have been compared: sensory profiling, Temporal Dominance of Sensations and free sorting task. These methodologies present drawbacks: sensory profile and TDS do not provide an effective discrimination of the taste of water and the free sorting task is efficient but does not enable data aggregation. A new methodology based on comparison with a set of references and named “Polarized Sensory Positioning” (PSP) has been developed enabling to easily define the sensory characteristics of water without presenting too many samples. Finally, this method provides a new type of sensory data requesting dedicated data analysis.

Abstract

WOS: 000274743300016; International audience; 5-Hydroxymethylfurfural (5-HMF) is known as an indicator of quality deterioration in a wide range of foods. 5-HMF is formed as an intermediate in the Maillard reaction and has been identified in a wide variety of heat-processed foods. In recent years, the presence of 5-HMF in foods has raised toxicological concerns: data have shown cytotoxic, genotoxic and tumoral effects but further studies suggest that 5-HMF does not pose a serious health risk. However the subject is still a matter of debate. We investigated the genotoxicity of the food-borne contaminant 5-HMF using the Ames test, the micronucleus (MN) and the single-cell gel electrophoresis (SCGE) assays in the human metabolically active HepG2 cell line. Cytotoxic effect of 5-HMF was first assessed using Alamar Blue (TM) as a sensitive sub-lethal assay. 5-HMF did not induce any genic mutation in bacteria whatever the concentration in the Ames test. Furthermore, it does not induce clastogenic or aneugenic effects in the HepG2 cells. In contrast, 5-HMF induced HepG2 DNA damage at concentrations from 7.87 to 25 mM in the comet assay suggesting a weak genotoxic effect of 5-HMF in the HepG2 cells probably repaired.

Abstract

1095-8312 10.1111/j.1095-8312.2009.01348.x; In the present study, trail pheromone blends are identified for the first time in termites. In the phylogenetically complex Nasutitermitinae, trail-following pheromones are composed of dodecatrienol and neocembrene, the proportions of which vary according to species, although neocembrene is always more abundant than dodecatrienol (by 252013250-fold). Depending on species, termites were more sensitive to dodecatrienol or to neocembrene but the association of both components always elicited significantly higher trail following, with a clear synergistic effect in most of the studied species. A third component, trinervitatriene, was identified in the sternal gland secretion of several species, but its function remains unknown. The secretion of trail pheromone blends appears to be an important step in the evolution of chemical communication in termites. The pheromone optimizes foraging, and promotes their ecological success.††© 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 99, 20201327.

Abstract

International audience; In the context of an evolutionary study of the chemical communication in termites, sex pheromones and trail-following pheromones were investigated in two Termopsidae, Zootermopsis nevadensis and Z. angusticollis. In these species, in which the presence of sex-specific pheromones has been demonstrated previously, the chemical structure of the female sex pheromone has now been identified as (5E)-2,6,10-trimethylundeca-5,9-dienal and the male sex pheromone as (+)- or (-)-syn-4,6-dimethyldodecanal. The amount of sex pheromone was estimated at 5–10 ng per individual in females and 2–5 ng in males. Because these two sympatric species do not differ in their pheromonal chemical composition, reproductive isolation is probably mediated chiefly by differences in dispersal flight chronology. The trail-following pheromone was shown to be composed of the same compound as the male sex pheromone, that is syn-4,6-dimethyldodecanal. The compound syn-4,6-dimethyldodecanal was 10 times more active than the racemic (+/-)-syn + (+/-)-anti-4,6-dimethyldodecanal in eliciting trail-following. The amount of syn-4,6-dimethyldodecanal was estimated at 0.1–0.5 ng per pseudergate. Regarding the phylogenetic aspects, the nature of the female sex pheromone of Zootermopsis is structurally akin to the trail-following pheromone of Mastotermes darwiniensis of Mastotermitidae and Porotermes adamsoni and Stolotermes victoriensis of Termopsidae. Interestingly, the nature of the trail-following pheromone of the Termopsinae Zootermopsis is clearly different from that of the Porotermitinae P. adamsoni and the Stolotermitinae S. victoriensis, which mirrors recent molecular data on the paraphyly of Termopsidae.

Abstract

Research Article; Partition coefficients give an indication of the retention of aroma compounds by the food matrix. Data in the literature are obtained by various methods, under various conditions and expressed in various units, and it is thus difficult to compare the results. The aim of the present study was first to obtain gas/water and gas/matrix partition coefficients of selected aroma compounds, at different temperatures, in order to calculate thermodynamic parameters and second to compare the retention of these aroma compounds in different food matrices.RESULTS: Yogurts containing lipids and proteins induced a higher retention of aroma compounds than model gel matrices. The observed effects strongly depend on hydrophobicity of aroma compounds showing a retention for ethyl hexanoate and a salting out effect for ethyl acetate. A small but noticeable decrease in enthalpy of affinity is observed for ethyl butyrate and ethyl hexanoate between water and food matrices, suggesting that the energy needed for the volatilization is lower in matrices than in water.CONCLUSION: The composition and complexity of a food matrix influence gas/matrix partition coefficients or aroma compounds in function of their hydrophobicity and to a lower extent enthalpy of vaporization.

Abstract

www.elsevier.com/locate/foodchem ; FSTA:2010-Sp0197; International audience; Delipidation was studied as a way to dearomatise a non-conventional protein powder obtained from Eisenia foetida earthworms. In the first step, we studied the impact of several factors such as solvent type, extraction method and particle size on the yield of extracted lipids. Lipid extraction from samples was considerably improved using an ultrasound method with a chloroform/methanol mixture and small particle size. In the second step, the volatile compounds were extracted from the delipidated protein powder by the SAFE extraction method and by the HS-SPME method, and were further analysed by GC-MS. The chloroform/methanol mixture and the ultrasound method extracted a wide range of volatile compounds very efficiently. Moreover, whatever method was used to extract the lipids, the volatile compounds detected in the headspace of the delipidated powder represented less than ¼ of the volatile compounds detected in the headspace of the regular powder.

Abstract

WOS: 000274095800047 ; http://www.elsevier.com/locate/foodres; International audience; The gelation mechanism of carrageenan depends on the amount and nature of the polysaccharide, and is cation sensitive. From a theological approach, this specificity leads to different textural properties. In composite gels with carrageenans, starch and sucrose, the presence Of kappa/kappa 2-carrageenan, even at low levels, has an impact on textural and structural properties. In this study, theological and diffusion NMR measurements were performed on composite gels to probe gel structure at the macro- and micro-scale. Variations were made in the gel composition by varying the carrageenan content and the nature of the polysaccharide and cations. We showed that all the factors that increased the rigidity of the composite gels - polysaccharide content and specific cations - decreased significantly the diffusion of small molecules such as sucrose and ethyl butyrate.

Abstract

International audience; Amitermes evuncifer (Termitidae, Termitinae) is a pest termite in several countries of Africa, damaging crops and buildings. The trail-following pheromone of this termite was isolated from worker sternal glands and identified by GC-MS after solid phase microextraction (SPME). The pheromone is composed of (3Z,67,8E)-dodeca-3,6,8-trien-1-ol (dodecatrienol) and neocembrene acting in synergy, neocembrene being 5-10 times more abundant than dodecatrienol. Dodecatrienol alone is able to elicit trail-following in workers, whereas neocembrene alone is inactive. However, the association of both components induces a significantly higher trail-following activity. Multicomponent trail-following pheromones were only known, until now, in the Termitidae Nasutitermitinae, and in the Rhinotermitidae Prorhinotermes.

Abstract

Background Dietary long-chain polyunsaturated fatty acids (LC-PUFA) are of crucial importance for the development of neural tissues. The aim of this study was to evaluate the impact of a dietary supplementation in n-3 fatty acids in female rats during gestation and lactation on fatty acid pattern in brain glial cells phosphatidylethanolamine (PE) and phosphatidylserine (PS) in the neonates. Methods Sprague-Dawley rats were fed during the whole gestation and lactation period with a diet containing either docosahexaenoic acid (DHA, 0.55%) and eicosapentaenoic acid (EPA, 0.75% of total fatty acids) or α-linolenic acid (ALA, 2.90%). At two weeks of age, gastric content and brain glial cell PE and PS of rat neonates were analyzed for their fatty acid and dimethylacetal (DMA) profile. Data were analyzed by bivariate and multivariate statistics. Results In the neonates from the group fed with n-3 LC-PUFA, the DHA level in gastric content (+65%, P < 0.0001) and brain glial cell PE (+18%, P = 0.0001) and PS (+15%, P = 0.0009) were significantly increased compared to the ALA group. The filtered correlation analysis (P < 0.05) underlined that levels of dihomo-γ-linolenic acid (DGLA), DHA and n-3 docosapentaenoic acid (DPA) were negatively correlated with arachidonic acid (ARA) and n-6 DPA in PE of brain glial cells. No significant correlation between n-3 and n-6 LC-PUFA were found in the PS dataset. DMA level in PE was negatively correlated with n-6 DPA. DMA were found to occur in brain glial cell PS fraction; in this class DMA level was correlated negatively with DHA and positively with ARA. Conclusion The present study confirms that early supplementation of maternal diet with n-3 fatty acids supplied as LC-PUFA is more efficient in increasing n-3 in brain glial cell PE and PS in the neonate than ALA. Negative correlation between n-6 DPA, a conventional marker of DHA deficiency, and DMA in PE suggests n-6 DPA that potentially be considered as a marker of tissue ethanolamine plasmalogen status. The combination of multivariate and bivariate statistics allowed to underline that the accretion pattern of n-3 LC-PUFA in PE and PS differ.

Abstract

Aim: The composition of the meibum of blepharitis patients is characterised by increased levels of branched-chain fatty acids (BCFAs) that return to normal values in patients treated with cyclins and lid hygiene. The aim of this study was to determine if BCFAs had toxic effects on conjunctival cells related to the disease. Methods: Chang and IOBA-NHC conjunctival human cells were treated with BCFAs (isoC16 and isoC20) or palmitic acid as a control for 4 h or 24 h at 50 μM or 100 μM. Morphological and functional changes were investigated by measuring mitochondrial dehydrogenase activity, cell permeability, mitochondrial depolarisation, chromatin condensation, IL-1β and reactive oxygen species production.Results: None of the fatty acids modified the parameters of cytotoxicity in conjunctival cells in Chang or IOBA-NHC cell lines. Only the mitochondrial dehydrogenase activity was significantly decreased in relation to the isoC20 concentration increase.Conclusions: The increase in BCFAs in the tears of blepharitis patients does not consistently participate in the conjunctival cell changes throughout the course of the disease. Instead, it is likely an adaptive response of the ocular surface to the lack of tears, possibly increasing meibum fluidity, thus enhancing lacrimal film stability. Footnotes

Abstract

Purpose: 24S-Hydroxycholesterol is formed by enzymatic oxidation of cholesterol via cholesterol-24S-hydroxylase (CYP46A1) activity in neurons, including retinal ganglion cells and neurons from the inner retina. We investigated whether neurodegeneration could be associated with the release of 24S-hydroxycholesterol in acute neuropathies, and therefore 24S-hydroxycholesterol could be considered as a biomarker of retinal cell degeneration in the course of optic neuropathies. Methods: Retinal neurodegeneration was induced in rats by severe elevation of intra-ocular pressure. For that purpose, rats were submitted to 532nm-laser photocoagulation of the episcleral veins, limbus and trabecular meshwork. Intra-ocular pressure was monitored in a time course study at 1, 3, 7, 14, 21, 30 and 60 days post laser injury using Tonolab®. Rat retinal and plasma 24S-hydroxycholesterol levels were quantified by gas-chromatography mass spectrometry using deuterated internal standard at the same time points. Plasma levels of 24S-hydroxycholesterol were similarly monitored in patients suffering from anterior ischemic optic neuropathy. Results: Intra-ocular pressure was significantly raised by a factor of five in the laser treated-eyes of the rats compared to fellow eyes, during the first two weeks after photocoagulation, and returned to baseline afterwards. The levels of 24S-hydroxycholesterolwere lowered in the first three days in the retina injured by laser, compared to fellow eye. Meanwhile, plasma levels of 24S-hydroxycholesterolwere raised by a factor of three. Patients suffering from anterior ischemic optic neuropathy showed increased plasma levels of 24S-hydroxycholesterol, compared to age-matched normal subjects (H=6.86, P=0.009 by Kruskal-Wallis test). Conclusions: Increased plasma levels of 24S-hydroxycholesterol were associated with acute phases of optic neuropathies, suggesting its relevance as a biomarker of retinal neurodegeneration.

Abstract

The nasal mucosa is a specialist interfacial region sandwiched between the olfactory system and the gaseous chemical milieu. In mammals and insects, this region is rich in odorant-binding proteins that are thought to aid olfaction by assisting mass transfer of the many different organoleptic compounds that make up the olfactory landscape. However, in mammals at least, our grasp on the exact function of odorant-binding proteins is tentative and better insight into the role of these proteins is warranted, not least because of their apparent significance in the olfactory systems of insects. Here, the crystal structure of rat odorant-binding protein 1 is reported at 1.6 Å resolution. This protein is one of the best-characterized mammalian odorant-binding proteins and only the third such protein structure to be solved at high resolution. The protein was crystallized in the holo form and contains an unidentifiable ligand that is probably an artefact from the Pichia pastoris expression system. Comparisons are made between this structure and a modelled OBP1 structure produced using the crystal structure of aphrodisin as a template. Comparisons are also made between OBP1 and the other two rat OBP subtypes, for which crystallographic data are unavailable. Interestingly, we also show that OBP1 is monomeric, which is in contrast to its previous assignment.

Abstract

Milk oxidoreduction potential was modified using gases during the production of a model dairy product and its effect on gel setting was studied. Acidification by glucono-delta-lactone was used to examine the physicochemistry of gelation and to avoid variations due to microorganisms sensitive to oxidoreduction potential. Four conditions of oxidoreduction potential were applied to milk: milk was gassed with air, nongassed, gassed with N(2), or gassed with N(2)H(2). The rheological properties and microstructure of these gels were determined using viscoelasticimetry, measurement of whey separation, and confocal laser scanning microscopy. It appeared that a reducing environment led to less-aggregated proteins within the matrix and consequently decreased whey separation significantly. The use of gas to modify oxidoreduction potential is a possible way to improve the quality of dairy products.

Abstract

Physicochemical properties (partition and diffusion coefficients) involved in the mobility and release of salt and aroma compounds in model cheeses were determined in this study. The values of NaCl water/product partition coefficients highlighted interactions between proteins and NaCl. However, these interactions were not modified by the product composition or structure. On the contrary, model cheese composition and structure influenced NaCl diffusion and both partition and diffusion for aroma compounds. Analysis of in-nose measurements of aroma release during eating, with regard to physicochemical properties, showed that product and aroma properties partly contributed to flavor release. Depending on the model cheese composition, structure and firmness, physicochemical properties, food breakdown, and chewing behavior can lead to different aroma release profiles. Finally, a discussion of all the results with regard to salt and flavor perception of the model cheese showed that both physicochemical and cognitive mechanisms contributed to perception.

Abstract

International audience; The objective of this study was to assess the impact of nutritional information on the willingness to pay for bread. Four French baguettes were presented to 123 consumers who firstly gave liking scores in three evaluation conditions, and who then gave their maximum price (reservation price) they were ready to pay in two information steps. In the first step, the baguettes were presented without any information about their composition. Following this, half the participants received information about the potential health benefits of fibre. In the second step, two baguettes were presented with a ‘source of fibre' label. A similar product hierarchy was observed between hedonic scores and reservation prices. In addition, a significant effect was found on the reservation prices when the ‘source of fibre' label was presented, but no effect was observed when the information concerning the potential health benefits of fibre was given.

Abstract

10.1007/s00049-009-0017-7; Abstract (Z)-Dodec-3-en-1-ol has been identified as the major component of the trail-following pheromone of nine species of Kalotermitidae belonging to six different genera, suggesting that this compound represents a common signal in this family of termites. The homogeneous nature of trail-following pheromones of Kalotermitidae well agrees with the monophyly of this family. It also supports the postulated position of this family as a sister group of the Rhinotermitidae and Termitidae, which also secrete C12-alcohols as trail-following pheromones. The significance of a trail pheromone in termites of the ‘one-piece' life type, which spend their whole life within the same piece of wood, is discussed.
