Impact of the crystal size of beta zeolite on the structural quality of zeolite templated carbons]]> The impact of the crystal size of the template zeolite on the textural properties of resulting Zeolite Templated Carbons was studied using nano- (20 nm) and micron-sized (5 μm) zeolite beta crystals. ZTCs were obtained for both nano- and micron-sized zeolite beta crystals, yet for the micron-sized sample the presence of supermicropores and small mesopores was detected, indicating a higher degree of structural defects during the templating process and hence in the final ZTC. The insights gained from nitrogen physisorption were confirmed by TEM, TGA and XPS. Despite, long range structural order, evidenced by X-ray powder diffraction (XRD) for both, nano- and micron-sized ZTCs was inferred. These results suggests that XRD patterns allow to evidence the well-ordered part of the sample but might not be the method of choice for characterizing the structural quality of ZTCs. Simulated XRD powder patterns allowed to propose a graphene-based nanoribbon structure grown in the zeolite pores as a satisfactory model for ZTCs in beta zeolite.

tropical disease currently affecting millions of people worldwide. Incomplete knowledge on the parasite biochemistry contributes, at least partially, to the limited development of useful biotechnological advances for the infection control. In this sense, little information is available regarding post-translational modifications (PTMs) occurring in E. granulosus s.l. proteins, which ultimately may affect the performance of biotechnological products to be developed. Therefore, we report here a proteomic analysis of the parasite PTMs identified through FindMod software applied to a set of tegumental proteins previously characterized by mass spectrometry
(MALDI-TOF/TOF) analysis of protein spots from a 2D electrophoresis gel. Manual searches for already annotated
proteins exhibiting such PTMs were also performed within proteome databases of E. granulosus s.l. and other platyhelminthes. In addition, key enzymes involved in PTMs modifications were searched for within E. granulosus s.l. proteome. Finally, the presence of selected PTMs was further confirmed by a high-resolution proteomic approach (nanoLC-MS/MS). A set of 22 different PTMs most likely to be present in the parasite was suggested, 9 of them with high confidence as they were identified in the same m/z fragment by both proteomic techniques (acetylation, deamidation, deamidation followed by methylation, mono- and dihydroxylation,
mono- and di-methylation, S-nitrosylation and phosphorylation). Interestingly, 5 PTMs were herein identified for the first time in E. granulosus s.l. proteins. Our results expand the scarcely studied topic of PTMs in platyhelminthes.

]]> To tackle current nutritional issues like obesity, it could be valuable to involve children in the development of healthy food products that they will actively chose and enjoy. The aims of the present exploratory study were (i) to assess a methodology for early-stage idea generation through co-creation, for the development of healthy snacks with pre-adolescents, and (ii) to compare two settings, creative focus groups (CFG) and an online community (ONL). Three steps were defined to allow the gradual exploration of the topic and mutual learning
throughout the process: (1) Show &Tell: photo taking and -elicitation to understand what children ate; (2) Reflect: a sorting task of the pictures to discuss and reflect on snacking practices (3) Create: an idea generation step, in which a newspaper article describing an idea for a new healthy snack was created. To increase engagement and creativity, gamification strategies were used. Our results demonstrated that children (preadolescents) can create new food product ideas with the proposed process, using enabling and creative techniques. In the CFG the trained moderator could steer the group to the co-creation goal. The setting facilitated teamwork and group learning, collaborative ideas considering preferences of peers and produced a few detailed and mostly actionable ideas. In the ONL less control over the process was possible. The setting produced many ideas varying in the degree of
detail and actionability focusing on individual preferences. The feedback and observations from our study, particularly in the CFG setting, implied that the creative approach was highly engaging for participants. Further research is necessary to assess the potential of initial ideas developed by pre- adolescents.

The present study aimed to measure children’s implicit and explicit basic emotions elicited by tasting, through the use of facial decoding and compare them to children’s liking ratings in a case study with flavoured chocolate milk samples. Children aged 9–10 participated in the study (n = 48). Six samples based on two design of experiment factors Added sugar (yes / no) and Surprise flavour (peppermint / liquorice/ no added flavour) were tested. The software iMotions with the AFFDEX algorithm was used for facial decoding. For each sample, facial expression was measured immediately after tasting (implicit basic emotions). Then, children were asked to show a facial expression related to their feelings when they tasted the chocolate milk (explicit basic emotions) and rate their liking on a 7-point-scale.

Implicit and explicit basic emotion likelihoods from facial decoding were correlated to liking ratings regarding the factor Surprise flavour. As in previous studies, the measurement of implicit basic emotions discriminated samples according to negative emotions (anger and disgust) which had higher likelihoods in disliked samples with Surprise flavour (peppermint and liquorice). Facial decoding of explicit basic emotions was the only measurement discriminating samples also according to the factor Added sugar, an advantage over liking ratings. The positive emotion joy, as well as negative emotions (sadness, fear, anger, disgust and contempt), were significant in the explicit evaluation. The results add to previous literature suggesting that the measurement of implicit emotions via facial decoding can be useful to study negative emotions. Further, explicit basic emotions enhanced the discrimination of liked samples with the involved age group.

Their implicit bias towards pictures of snacks was measured via AAT. The test instruction was based on pushing or pulling the joystick according to picture category, food vs. non-food: food (18 snack pictures varying in sweetness and calorie) vs. non-food (18 pictures visually similar to the respective food stimuli). Further, children rated their expected liking of the snack pictures, answered an attitude questionnaire related to health and sugar consumption, and completed two paired preference tests tasting real samples under blind condition and choosing between a sugar and no-sugar added chocolate milk take-home pack.
The percentage of non-valid AAT responses was relatively high, leading to low testing power. There was a significant difference in approach bias between food pictures and non-food pictures; approach bias was positive for food and slightly negative for non-food. Within food pictures, no significant effect of sweetness nor calorie was found. Nevertheless, children’s approach biases were linked to their expected liking ratings, which revealed a clear preference towards high sweetness and high calorie snacks. Individual differences in children’s approach bias to pictures differing in sweetness and calorie content were related to their hunger state but not to their attitudes or preference towards chocolate milk, indicating relevance for situational food choices. In the present study, questionnaire-based measurements (affective and cognitive attitude towards sugar, sugar craving and using food as reward) were however associated with children’s preference towards chocolate milk (blind and/or informed). Higher scores in the measured attitude subscales craving for sweet food, using food as reward, affective attitude towards sweet food and cognitive attitude towards sweet food were associated with higher odds to choose the sugar added chocolate milk. Methodological considerations and recommendations with regards to the use of approachavoidance testing with children are critically discussed.]]> Galler, Martina]]> Mikkelsen, Emma]]> Næs, Tormod]]> Liland, Kristian Hovde]]> Ares, Gastón]]> Varela, Paula]]> Información sobre Derechos de Autor

Here we describe a “ready-to-use” homogeneous competitive immunosensor with an assay time of 10 min that is based exclusively on recombinant reagents. The signal is produced when the split fragments of the nano luciferase (Nluc) are brought together by the interaction of a heavy chain only variable domain (VHH) with a peptidomimetic of the target small molecule. A VHH to 2,4-dichlorophenoxyacetic acid (2,4-D) was used to isolated the peptidomimetic (NGFFEPWQVVYV)
from phage display libraries using six panning conditions. Then the peptidomimetic and VHH were fused with the larger (LgN) and smaller piece (SmN) of split fragments of Nluc, respectively. In order to optimize the signal and sensitivity of the immunosensor, we explored the effects of the spacer between the peptidomimetic and LgN, the copy number of peptidomimetics, and the spacer between SmN and VHH, generating 24 combinations that allowed to conclude on their respective roles. Eventually, the developed “ready-to-use” immunosensor performed excellent signal-to-noise ratio and sensitivity, and could be applied to the detection of 2,4-D in real samples. Meanwhile, the immunosensor totally realizes labeling-free, immobilization-free and washing-free, also can be
produced in a highly cost effective way.

The main objective of this study was to compare the performance of three OL extracts obtained by different extraction techniques in protecting canola oil against oxidative damage. The technologies evaluated were maceration with ethanol/water 75:25 (v/v), supercritical fluid extraction with CO2 (SC–CO2) and SC-CO2 with 10% ethanol as modifier (SC–CO2/EtOH). Each extract was analyzed as for total phenolic compounds (TPC), antioxidant activity (ABTS assay) and phenolic composition by reversed phase liquid chromatography-quadrupole-time of flight mass spectrometry. The oxidative stability of canola oil with or without the incorporation of 250 mg/kg of each extract was assessed during five weeks of
storage at 60 ◦C. Peroxide, K232, K270, and Rancimat values, besides tocopherols content were determined.
Macerated extract showed the highest TPC and antioxidant activity, but both SC-CO2 extracts were more effective in preserving tocopherols. In addition, SC-CO2 extracts delayed the oxidation progress as they lead to higher induction periods than control and macerated extracts, and a slower increase in peroxide values. Results obtained reinforce the use of supercritical fluid technology to obtain antioxidants compounds from natural sources.

understand their role in biological processes, both normal and
pathological. Immobilized glycoenzymes are excellent tools
for this purpose as they can selectively release glycans from
glycoproteins without altering their backbone. They can be
easily removed from the reaction mixture avoiding their
interference in subsequent experiments. Here, we describe the
immobilization of peptide-N-glycosidase F (PNGase F) onto
silica magnetic nanoparticles with immobilization yields of
86% and activity yields of 12%. Immobilized PNGase F showed
higher thermal stability than its soluble counterpart, and could
be reused for at least seven deglycosylation cycles. It was
efficient in the deglycosylation of several glycoproteins
(ribonuclease B, bovine fetuin, and ovalbumin) and a protein
lysate from the parasite Fasciola hepatica under native
conditions, with similar performance to that of the soluble
enzyme. Successful deglycosylation was evidenced by a
decrease in specific lectin recognition of the glycoproteins
(40%–80%). Moreover, deglycosylated F. hepatica lysate
allowed us to confirm the role of parasite N-glycans in the
inhibition of the lipopolysaccharide-induced maturation of
dendritic cells. Immobilized PNGase F probed to be a robust
biotechnological tool for deglycosylation of glycoproteins and
complex biological samples under native conditions.

boosted regression trees (BRT). Specifically, the focus was on how socio-demographic characteristics and personality traits linked to risk perception and time orientation impact on discretionary salt consumption patterns. For this purpose, an online cross-sectional survey with a convenience sample of 498 Uruguayan participants was carried out. Participants completed the consideration of future consequences (CFC) scale adapted for eating behaviour, a short survey about discretionary salt consumption patterns and indicated their degree of agreement
with statements measuring perceived risk of sodium consumption. Finally, socio-demographic data were
collected. BRT were applied to build predictive models that related discretionary salt usage to socio-demographic
characteristics, the two factors of the CFC-Food scale (consideration of the future and consideration of the immediate
consequences of eating behaviour), and the two factors of the perceived risk of sodium consumption scale (severity of perceived risks and risk compensation). Age, time orientation and perceived risk were the most relevant explanatory variables for discretionary salt usage. Older people had a lower likelihood of adding salt to food, either at home or when eating out. In addition, individuals who tend to be present rather than future
oriented, as well as those with low perception of risk severity and susceptibility were more likely to add salt to foods. Results from the present work suggest that communication campaigns to reduce discretionary salt intake should mainly focus on stressing the short-term health benefits of reducing sodium intake and raising perceived susceptibility.

Co-creation is a potential approach to bridge the world of the child and the grown-up product developer. In this context, the objective of the present work was to explore the potential of a cocreation approach with children to develop a healthy dairy product. A total of 52 school-aged children (54%
girls, 6–13 year old) recruited from an after-school club in Montevideo (Uruguay) participated in co-creation workshops. Two sessions were carried out. In the first session, children developed a dairy product using a set of ingredients and proposed strategies to promote their product. Children showed a high level of engagement during the activity and provided actionable ideas for product development. Three key factors drove the product formulation (familiarity, hedonics, and healthiness), whereas common communication strategies were proposed by the participants to promote their products. In the second session, children evaluated four products developed
by the researchers based on children’s ideas. The products showed high overall liking scores (5.9 to 7.9) despite the inclusion of novel and healthy ingredients and the lower sugar content compared to similar commercial products available in the Uruguayan marketplace. These results show the potential of involving children in the co-creation of healthy dairy products. Considering the lack of published studies regarding the use of co-creation approaches with children in the food domain, the present work provides useful insights for the implementation of
co-creation to develop innovative products with and for children.

Household food waste is a complex phenomenon determined by consumer behavior along the steps of the “food journey” that goes from purchasing to final disposal. Although avoiding food waste is socially desirable and raises positive attitudes, consumers do not frequently engage in avoidance behaviors. The objectives of the present work were: i) to explore the views of Uruguayan citizens on household food waste, and ii) to identify drivers of food waste among Uruguayan households. A total of 20 in-depth interviews based on a semi-structured guide were conducted by telephone. Participants were asked to recall and describe the last time
they discarded food, as well as to describe the most common food waste situations in their household, the most commonly used strategies to avoid food waste and how they could reduce it. The transcripts were analyzed using content analysis based on a deductive-inductive approach. Interviews revealed that most of the participants perceived food waste in their homes as null or low, whereas food waste in the country was regarded as high. When participants described food waste incidents, they perceived it as ’unavoidable’, suggesting that they tended
to find a rational explanation outside of their will to justify their behavior. Participants’ discourses enabled the identification of drivers related to behavioral factors, personal factors, product factors, and contextual factors. Results stress that most promising entry points for communication campaigns and intervention programs to reduce household food waste should focus on behavioral factors, planning throughout all the household stages of the food journey and the provision of knowledge and skills on food storage, handling, and preparation.
