Quittor, an obsolete disease
2012
Quittor was a disease of the pastern and crown area of the ungulates. It was quite common in the horse until the early twentieth century. It was characterized by necrosis manifested by a mass, outward symptom of a phlegmon, which ulcerated and expelled necrotic tissue. The hippiatric healers and early veterinarians generally recognized four forms, the most dangerous was the necrosis of fibrocartilages of the foot. Treatment involved excision of the latter which involved a spectacular operating manual. This action marked the beginning of the veterinary profession, until the disappearance of the disease that was a result of the mechanization of agriculture and transport. It is now very uncomm…
Sensory methodology developed for the investigation of sciaccarello wine concept
2004
<p style="text-align: justify;">The aim of the present work was to underline the existence of a sensory space relevant to Sciaccarello wines. Twenty-eight wines were selected for viticultural and enological characteristics, using 1/2 Sciaccarello/Non- Sciaccarello ratio. Sensory analyses (orthonasal then overall perceptions) were performed with a panel composed of seventeen judges. All of the judges were experienced in Sciaccarello wines knowledge. Statistical treatment by PCA was first carried out to display the consensus between the assessors. ANOVA was performed to discriminate accurate and inaccurate examples of Sciaccarello wines. This study demonstrated the existence of the sens…
Assessing the effect of information on the reservation price for Champagne: what are consumers actually paying for?
2018
AbstractTwo series of Vickrey auctions have been performed to assess the effect of packaging information (bottle and label) on the reservation prices of ordinary consumers for five brut non-vintage Champagnes. As in other studies on wine tasting, packaging information is found to explain much more of the variation in willingness to pay than sensory information. Participants are unable, or unwilling, to put different values on the Champagnes after blind tasting, but significant differences in reservation prices appear when labels are disclosed. Detailed analysis of choices reveals a large heterogeneity in individual behaviors and valuations of the Champagnes included in this study. (JEL Clas…
Performances of neural networks for deriving LAI estimates from existing CYCLOPES and MODIS products
2008
International audience; This paper evaluates the performances of a neural network approach to estimate LAI from CYCLOPES and MODIS nadir normalized reflectance and LAI products. A data base was generated from these products over the BELMANIP sites during the 2001-2003 period. Data were aggregated at 3 km x 3 km, resampled at 1/16 days temporal frequency and filtered to reject outliers. VEGETATION and MODIS reflectances show very consistent values in the red, near infrared and short wave infrared bands. Neural networks were trained over part of this data base for each of the 6 MODIS biome classes to retrieve both MODIS and CYCLOPES LAI products. Results show very good performances of neural …
A multiple-response chi-square framework for the analysis of Free-Comment and Check-All-That-Apply data
2021
International audience; Free-Comment (FC) and Check-All-That-Apply (CATA) provide a contingency table containing citation counts of descriptors by products. The analyses performed on this table are most often related to the chi-square statistic. However, such practices are not well suited because they consider experimental units as being the citations (one descriptor for one product by one subject) while the evaluations (vector of citations for one product by one subject) should be considered instead. This results in incorrect expected frequencies under the null hypothesis of independence between products and descriptors and thus in an incorrect chi-square statistic. Thus, analyses related …
Guidance on allergenicity assessment of genetically modified plants
2017
Abstract This document provides supplementary guidance on specific topics for the allergenicity risk assessment of genetically modified plants. In particular, it supplements general recommendations outlined in previous EFSA GMO Panel guidelines and Implementing Regulation (EU) No 503/2013. The topics addressed are non‐IgE‐mediated adverse immune reactions to foods, in vitro protein digestibility tests and endogenous allergenicity. New scientific and regulatory developments regarding these three topics are described in this document. Considerations on the practical implementation of those developments in the risk assessment of genetically modified plants are discussed and recommended, where …
Estabilidad de antocianinas durante el almacenamiento de jugos de arándanos
2016
Resumen: Antecedentes: Los arándanos y productos de arándano tienen alto valor nutricional, especialmente por su alto contenido de antocianinas. Estas son potentes antioxidantes y poseen alta capacidad de secuestrar radicales libres. Así, los arándanos y productos de arándanos han resultado atractivos para los consumidores interesados en alimentos funcionales. Sin embargo, los tratamientos térmicos y posterior almacenamiento de productos alimenticios influyen en el contenido de antocianinas. La cinética de degradación de las antocianinas puede ser evaluada desde una perspectiva termodinámica, basada en funciones como energía libre, entalpía, entropía y energía de activación. Objetivos: Se e…
Biostimulant Potential of Humic Acids Extracted From an Amendment Obtained via Combination of Olive Mill Wastewaters (OMW) and a Pre-treated Organic …
2018
Olive mill wastewaters (OMW) detain contain significant levels of phenolic compounds with antimicrobial/phytotoxic activity and high amounts of undecomposed organic matter that may a high pollutant load that exerts negative effects on soil biology because of significant levels in phenolic compounds with antimicrobial/phytotoxic activity and limited biodegradability, and high amounts of undecomposed organic matter. Among OMW detoxification techniques, those focusing on oxidative degradation of phenolic compounds are relevant those focusing on oxidative degradation of phenolic compounds to reduce their toxicity. The composting (bio-oxidation) process in particular, exploits exothermic oxidati…
Defining gut mycobiota for wild animals: a need for caution in assigning authentic resident fungal taxa
2021
Animal gut mycobiota, the community of fungi that reside within the gastrointestinal tract, make an important contribution to host health. Accordingly, there is an emerging interest to quantify the gut mycobiota of wild animals. However, many studies of wild animal gut mycobiota do not distinguish between the fungi that likely can reside within animal gastrointestinal tracts from the fungal taxa that are non-residents, such as macrofungi, lichens or plant symbionts/pathogens that can be ingested as part of the host’s diet. Confounding the non-resident and resident gut fungi may obscure attempts to identify processes associated with the authentic, resident gut mycobiota per se. To redress th…
Molecular mechanisms of primary and secondary mucosal immunity using avian infectious bronchitis virus as a model system
2007
Although mucosal immune responses are critical for protection of hosts from clinical illness and even mortality caused by mucosal pathogens, the molecular mechanism of mucosal immunity, which is independent of systemic immunity, remains elusive. To explore the mechanistic basis of mucosal protective immunity, gene transcriptional profiling in mucosal tissues was evaluated after the primary and secondary immunization of animals with an attenuated avian infectious bronchitis virus (IBV), a prototype of Coronavirus and a well-characterized mucosal pathogen. Results showed that a number of innate immune factors including toll-like receptors (TLRs), retinoic-acid-inducible gene-1 (RIG-1), type I…
