Full textNano-technological approaches are allowing the development of deliberately engineered nanomaterials (ENMs), presenting promising new applications for many industrial fields. Especially, ENMs possess unique properties and novel uses in food or food packaging materials such as the enhancement of texture, colour, flavour, nutrient stability and food packaging safety. Despite their innovative properties, there is an increasing concern about the possibility that human exposure to TiO2NPs may lead to significant adverse health effects. The International Agency for Research on Cancer (IARC) classified TiO2 as a human carcinogen group 2B because there was enough evidence that nano-TiO2 may cause lung cancer by inhalation. Although oral exposure was also debated by IARC, the final report was inconclusive due to non-existing standardized procedures for nano- TiO2 risk assessment. Due to the potential adverse effects of this ENMs and the lack of information regarding toxicological aspects over the oral exposure, in this Thesis we have carried out in vitro studies on the biological effects of TiO2NPs. For the aforementioned purpose, we set up and characterized, for the first time in our laboratory, an epithelial in vitro model that closely mimics the human small intestine. Thus, in our first study, we defined the best culture conditions for the alreadydescribed model, Caco-2/HT29/Raji-B. From our integrity and permeability findings, we confirmed that the best Caco-2/HT29 cell ratio is 90:10, respectively, as TEER values, paracellular LY permeability and the mucus shed formed correlated well with other studies. We also were able to detect the induction of M-like cells by TEM. Moreover, in order to monitor the proper barrier formation, we proposed a set of genes related to the cell junctional complexes, brush border enzymes, mucus shed components and M-cell markers. Finally, we tested the goodness of our epithelial in vitro model by exposing it to both TiO2NPs and SiO2NPs for 24 h. Our confocal results evidenced the potential adverse effects of TiO2NPs and SiO2NPs on the intestinal epithelium, as NPs internalization and NPs-cell nucleus interaction were observed. Because of the heightened interest in the identification, validation and standardization of the effects associated to exposures to new ENMs, our second study aimed to assess the effects of three different shapes of TiO2NPs (spheres, rods and wires) on the Caco-2/HT29 barrier. Our results demonstrated that the three types of TiO2NPs have the ability to impair the membrane’s integrity, translocate through the mucus shed and internalize in the cells, reaching the nucleus. Taking into account our confocal images results, we hypothesize that due to their shapes, nano-wires are more likely to cross paracellularly, while nano-spheres and nano-rods used intracellular passage to cross the intestinal epithelium. Despite previous evidence that relate the capability of TiO2NPs to produce ROS, we have not detected oxidatively DNA damage. However, and in accordance with the confocal images showing a great amount of NPscell nucleus events, we detected a slight but significant general DNA damage in the barrier’s cells. Finally, the third study was performed under the framework of an international mention carried out in the Biomedical Engineering Department at the Binghamton University (Binghamton, NY, USA). Nutrient absorption is one of the main and most important functions of the small intestine. Thus, to understand and evaluate whether ENPs can trigger physiological potential pathologies, the activity of the intestinal alkaline phosphatase (IAP), aminopeptidase-N (APN) and Na+/K+ ATPase enzymes were measured after exposing the Caco-2/HT29-MTX barrier to TiO2NPs and SiO2NPs for 4 h. Moreover, and in order to further mimic the physiological conditions of a real digestion, the Caco-2/HT29-MTX barrier was exposed to both NPs previously digested and co-cultured with both Escherichia coli and Lactobacillus rhamnosus, as examples of commensal microbiota.

Full textIn the present project of the Mood-On drink, which is made from potatoes and exotic fruits, its sustainability is shown through the different analyzes carried out in Metropolitan Lima. Likewise, this product is aimed at socioeconomic sectors A, B, C, and that are in the age range of 18 to 24 years. Similarly, we can indicate that although there is a consistent presence of RTD beverages in the Peruvian market, consumers do not identify with the already established products. Therefore, we can mention that the Lima market has a need that has not been met; either for lack of flavors or another key factor. In addition to this, to carry out the work, interviews were carried out with users to ratify the level of acceptance of the product, in turn, contact was made with the liquor stores through traditional and non-traditional means for estimating sales. Likewise, a food engineer was contracted to prepare the recipe, since different aspects of the RTD drink had to be considered. Finally, a total of S /. 27,261.72 so that production activities can begin and the net profit that will be generated in the first year is –S/39,186.95, S/60,913.85 in the second year and for the third year it would amount to S/613,802.47

Full textCoastal zones worldwide are home to a large diversity of ecosystem engineers that perform key functions such as the recycling of organic matter and nutrients. The habitats resulting from the biological activity of these species are exposed to numerous disturbances such as over harvesting and trampling or via coastal modification. In this context, it is becoming key to understand the functioning of these engineered habitats and how they are affected by increasing disturbances. During my PhD, I used the reef habitat built by the gregarious tubiculous polychaete Sabellaria alveolata as a study case. First, the environmental and biotic changes associated with the establishment of a S. alveolata reef and its increasing disturbance were assessed, focusing on sediment characteristics (e.g. grain-size distribution, organic matter content) along with taxonomic diversity and species assemblage. In the same vain, the third article looks into the trophic functioning of the reef community and a control community to understand the effects of the establishment of the engineer species on carbon transfers, successively looking at the whole consumer community, the primary consumers and the importance of autochthonous (microphytobenthos and Ulva sp.) vs allochthone (phytoplankton) food sources. In this part, I used carbon and nitrogen stable isotopes and different analytical approaches such as isotopic niche metrics and mixing models. Article 2 aims towards understanding the interactions between reef habitat complexity, autochthonous food source heterogeneity and spatial scales in explaining the carbon isotopic ratio variations of S. alveolata and an associated suspension-feeder. In the last two chapters, I address the functioning of the engineered habitat either directly, using benthic core incubations to measure biogeochemical fluxes (e.g. oxygen demand) or indirectly, through the use of integrative functional and isotopic diversity indices. This last part reveals the existence of an optimum value of S. alveolata density, used as a disturbance proxy, where the trophic niche and the biogeochemical functioning of the reef are both maximal

Full textFokus på miljön är idag större än någonsin. FN skriver i sin klimat agenda att de till 2030 siktar på att halveramatsvinnet per capita. Idag finns det hårda regleringar om hur livsmedel ska transporte-ras och förvaras, menfrån den sekund konsumenten tar ut exempelvis ett mjölkpaket ur kyldisken finns det bara få riktlinjer om hurprodukten bör förvaras. Om en kyld eller fryst produkt inte hålls inom det angivna temperaturspannet skerdet en ökning i den mikrobiologiska tillväxten i livsmed-let. Detta leder i sin tur att matvaran blir dålig eller, ivärsta fall, att konsumenten blir förgiftad. Idag sker det också en förändring i hur konsumenterna handlar sinalivsmedel och allt större vikt läggs på att konsumenten för sig själv ska genomföra sitt köp. Detta projekt fokuserar på att utveckla en lösning som ska hjälpa konsumenten att hålla sina matvaror tempereradeunder en viss tid. Projektet är genomfört i Stockholm under 20 veckor i samarbete med IKEA ofSweden i Älmhult. Målgruppen i detta projekt är den breda kundgrupp som IKEA erhåller. Med hjälp av enanvändarcentrerad designprocess går det här projektet genom de tre designfaserna; inspiration, idégenereringoch slutligen implementering. Projektet har formats av interaktion genom workshops med olika externa aktörerså som användare och fokusgrupper. Idégenereringsfasen resulterade i fyra stycken enklare koncept somavgränsades till två genom extern beslutsfattning med handledare från IKEA of Sweden. Under projektets gånghar prototyper använts tillsammans med användare för att evaluera användarvänligheten hos koncepten. Resultatet består av två stycken koncept; Behålla och Blåsa, som är ämnade att möta två olika kundgrupper somhar identifierats genom enkäter och intervjuer. Behålla är en mindre produkt som riktar sig till de användaresom tar med sig matlåda till jobbet eller skolan samt till dem som köper färre matvaror i butiken. Blåsa är, ikontrast till Behålla en större produkt, skapad med fokus på de kunder som köper fler kylda och frysta matvaror.Utöver detta har fyra färgvariation skapats av produkterna för att erbjuda IKEA alternativa utföranden. Dessakoncept är visualiserade med hjälp av renderingar som har gjort i Adobe Illustrator. Med dessa koncept kanIKEA utöka sin hållbarhets profil och erbjuda sina kunder två nya produkter för att hålla deras kylda och frystamatvaror kalla.

Resumo: Com a Revolução Científica e Tecnológica (1970), a informação e o conhecimento transformam-se em fontes de maior produtividade e de desenvolvimento socioeconômico. No mundo agrário, os Organismos Geneticamente Modificados, também denominados transgênicos, representam a conformação dessa nova dinâmica tecnológica internacional. Em uma economia diretamente enraizada na produção e uso de conhecimentos, este trabalho prima pela investigação da existência de uma monopolização das técnicas transgênicas por determinadas empresas e países restringindo as possibilidades de concorrência no setor de sementes geneticamente modificadas, o que prejudicaria países menos avançados em biotecnologia agrícola. Em que medida conhecimentos e tecnologias de ponta estão organizados em fluxos globais ou estão inseridos em uma estrutura assimétrica, estabelecendo uma divisão entre os países capazes de participar dos processos de geração de novas tecnologias agrícolas e aqueles que passivamente absorvem conhecimentos advindos do exterior? Como a polarização de conhecimentos e informações estratégicos acarretaria e perpetuaria desigualdades na economia global e quais são os mecanismos jurídicos e políticos que corroborariam essa concentração?
Abstract: In the Scientific-Technical Revolution (1970), information and knowledge are transformed in sources of higher productivity and socioeconomic development. In agriculture, the genetically modified organisms represent the conformation of that new international technological dynamic. In an economy directly rooted in the production and use of knowledge, this research primarily investigates the existence of a monopoly in the field of genetically modified seeds by certain companies and countries, which would undermine less advanced countries in agricultural biotechnology. To what extent are technology and information organized into global flows or in an asymmetric structure establishing a division between countries able to participate in the process of generating new agricultural technologies and those who passively absorb knowledge coming from outside? How the polarization of strategic knowledge and information would result and perpetuate inequalities in the global economy and what legal and political mechanisms support this concentration?
