New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data

2018

Made available in DSpace on 2018-12-11T16:52:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-03-02 The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-dens…

Positron Emission Tomography Imaging of Neurotensin Receptor-Positive Tumors with 68 Ga-Labeled Antagonists: The Chelate Makes the Difference Again

2021

Neurotensin receptor 1 (NTS1) is involved in the development and progression of numerous cancers, which makes it an interesting target for the development of diagnostic and therapeutic agents. A small molecule NTS1 antagonist, named [177Lu]Lu-IPN01087, is currently evaluated in phase I/II clinical trials for the targeted therapy of neurotensin receptor-positive cancers. In this study, we synthesized seven compounds based on the structure of NTS1 antagonists, bearing different chelating agents, and radiolabeled them with gallium-68 for PET imaging. These compounds were evaluated in vitro and in vivo in mice bearing a HT-29 xenograft. The compound [68Ga]Ga-bisNODAGA-16 showed a promising biod…

Protein-protein interaction (PPI) networks are associated with multiple types of biases partly rooted in technical limitations of the experimental techniques. Another source of bias are the different frequencies with which proteins have been studied for interaction partners. It is generally believed that proteins with a large number of interaction partners tend to be essential, evolutionarily conserved and involved in disease. It has been repeatedly reported that proteins driving tumor formation have a higher number of PPI partners. However, it has been noticed before that the degree distribution of PPI networks is biased towards disease proteins, which tend to have been studied more often …

Biogeographical patterns of soil molecular microbial biomass as influenced by soil characteristics and management

2011

Aim The spatial organization of soil microbial communities on large scales and the identification of environmental factors structuring their distribution have been little investigated. The overall objective of this study was to determine the spatial patterning of microbial biomass in soils over a wide extent and to rank the environmental filters most influencing this distribution.

Heritability of Lifetime Income

2013

Using 15 years of data on Finnish twins, we find that 24% (54%) of the variance of women’s (men’s) lifetime income is due to genetic factors and that the contribution of the shared environment is negligible. We link these figures to policy by showing that controlling for education reduces the variance share of genetics by 5-8 percentage points; by demonstrating that income uncertainty has a genetic component half the size of its variance share in lifetime income; and by exploring how the genetic heritability of lifetime income is related to the macroeconomic environment, as measured by GDP growth and the Gini-coefficient of income inequality.

Impact of the information provided to consumers on their willingness to pay for Champagne : comparison with hedonic scores

2002

International audience; L'étude a été effectuée afin de comparer deux mécanismes destinés à révéler les préférences des consommateurs : une enchère Vickrey qui mesure la disposition à payer, et un test hédonique classique. A travers ces deux méthodes, l'objectif était d'estimer les effets respectifs des caractéristiques sensorielles et de l'information externe sur l'évaluation de cinq champagnes brut non millésimés. Cent-ving-trois consommateurs ont été assignés au hasard aux deux groupes et ont utilisé l'une des méthodes. Quelle que soit la méthode, ils ont évalué les champagnes à l'aveugle, puis sur la base d'une présentation des bouteilles et, enfin, après l'observation de la bouteille e…

[Qualité attendue contre qualité perçue : arbitrage avec les prix]

2000

International audience; Cet article rend compte d'une étude menée afin de comparer le comportement des consommateurs qui doivent choisir des produits sous contrainte économique, selon deux conditions différentes : quand la qualité perçue est basée sur une attente générée par des images fabriquées et, à l'inverse, quand la qualité perçue est basée sur l'expérience sensorielle en présence d'images fabriquées. Les participants de l'expérience ont été choisis au hasard, dotés d'un budget réel et placés dans cinq situations différentes de prix/budget. Ils ont formulé leurs choix parmi six jus d'orange dans chaque situation prix/budget. Ce travail a été réalisé pour les deux conditions différente…

Salt and Aroma Compound Distributions Influence Flavour Release and Temporal Perception While Eating Hot-Served Flans.

2021

International audience; To counteract the negative effect of salt overconsumption on health, strategies have been developed to reduce the salt content in food products. Among them, two promising strategies based on odour-induced saltiness enhancement and the heterogeneous distribution of flavour compounds were combined and assessed in four-layer cream-based snacks. To investigate the relationship between saltiness enhancement, temporal release and perception of flavour compounds in hot snacks with heterogeneous distribution of salt and aroma compounds, complementary techniques were used: nose space PTR-Tof-MS (Proton Transfer Reaction-Time of Flight–Mass Spectrometry) to assess the release …

Role of biological control agents and physical treatments in maintaining the quality of fresh and minimally-processed fruit and vegetables

2019

International audience; Fruit and vegetables are an important part of human diets and provide multiple health benefits. However, due to the short shelf-life of fresh and minimally-processed fruit and vegetables, significant losses occur throughout the food distribution chain. Shelf-life extension requires preserving both the quality and safety of food products. The quality of fruit and vegetables, either fresh or fresh-cut, depends on many factors and can be determined by analytical or sensory evaluation methods. Among the various technologies used to maintain the quality and increase shelf-life of fresh and minimally-processed fruit and vegetables, biological control is a promising approac…

Congruencia en conocimientos y educación afectivo-sexual en personas con DI

2018

En la educación de las personas con diversidad funcional intelectual (DFI) es importante que los principales agentes implicados (usuarios/as, padres y profesionales que trabajan con ellos) posean criterios comunes acerca de los objetivos educativos en general, y especialmente, en el área de la sexualidad. Sin embargo, las tres perspectivas no siempre son coincidentes con las consecuencias que se derivan de ello. Teniendo en cuenta la importancia de la identificación de necesidades y metas comunes, planteamos este trabajo con el objetivo de conocer el grado de concordancia entre: 1) los conocimientos que los usuarios tienen sobre sexualidad y la que los padres y profesionales les atribuyen y…
