Estudio de perfilación de metabolitos secundarios de extractos vegetales obtenidos mediante técnicas y estrategias no convencionales para el desarrol…
2022
En esta tesis doctoral se desarrolló en el entorno de la economía verde y el reciclaje de residuos alimentarios estudiando diferentes técnicas de extracción no convencionales. En primer lugar, se aislaron polifenoles de matrices complejas producto del desperdicio de alimentos, como son las hojas de Moringa oleifera, mediante extracción asistida por ultrasonidos (UAE). El enfoque de diseño experimental permitió optimizar las mejores condiciones de extracción (MeOH:H2O 50:50, v/v, proporcion 1:60 Sólido/Líquido (S/L), 60°C, 60 min) para obtener un contenido fenólico total (TPC) de 13,4 mg expresados como equivalentes de ácido gálico (GAE)/g de materia seca. Por lo tanto, la caracterización y …
Electronic Sensor Technologies in Monitoring Quality of Tea: A Review.
2022
Tea, after water, is the most frequently consumed beverage in the world. The fermentation of tea leaves has a pivotal role in its quality and is usually monitored using the laboratory analytical instruments and olfactory perception of tea tasters. Developing electronic sensing platforms (ESPs), in terms of an electronic nose (e-nose), electronic tongue (e-tongue), and electronic eye (e-eye) equipped with progressive data processing algorithms, not only can accurately accelerate the consumer-based sensory quality assessment of tea, but also can define new standards for this bioactive product, to meet worldwide market demand. Using the complex data sets from electronic signals integrated with…
Molecular and Clinical Predictors of Quality of Life in Chronic Rhinosinusitis with Nasal Polyps
2023
(1) Background: Factors influencing the quality of life (QoL) of patients with chronic rhinosinusitis with nasal polyposis (CRSwNP) are poorly understood. We set out to determine the predictive factors on patients’ QoL using the Sino-Nasal Outcome Test-22 (SNOT-22); (2) Methods: An ambispective analysis of data from patients diagnosed with CRSwNP in our institution. All the patients underwent a nasal polyp biopsy and completed the SNOT-22 questionnaire. Demographic and molecular data as well as the SNOT-22 scores were collected. Patients were classified in six subgroups considering the presence of asthma, non-steroidal drugs (NSAID) intolerance and corticosteroid resistance; (3) Results: Th…
Faire tomber les masques du discours officiel de RDA par le défigement : le cas Volker Braun
2011
Soumis, accepté, en cours de publication; International audience; Cette contribution propose une analyse phraséologico-stylistique de deux romans est-allemands de Volker Braun, Hinze-Kunze-Roman et Unvollendete Geschichte. Le point de départ de l'analyse repose dans l'hypothèse selon laquelle un des meilleurs angles d'attaque pour l'étude de la variété d'allemand de RDA réside dans des catégories phraséologiques comme figement, pré-fabriqué langagier ou encore routinisation qui, contre toute attente dans un contexte contraint comme celui de RDA, n'interdisent pas - quand elle ne l'encouragent pas - un certain jeu avec le figement. Sur cette base, la suite de l'étude vise à montrer dans quel…
Cancer prevention with aspirin in hereditary colorectal cancer (Lynch syndrome), 10-year follow-up and registry-based 20-year data in the CAPP2 study…
2020
BACKGROUND: Lynch syndrome is associated with an increased risk of colorectal cancer and with a broader spectrum of cancers, especially endometrial cancer. In 2011, our group reported long-term cancer outcomes (mean follow-up 55·7 months [SD 31·4]) for participants with Lynch syndrome enrolled into a randomised trial of daily aspirin versus placebo. This report completes the planned 10-year follow-up to allow a longer-term assessment of the effect of taking regular aspirin in this high-risk population.METHODS: In the double-blind, randomised CAPP2 trial, 861 patients from 43 international centres worldwide (707 [82%] from Europe, 112 [13%] from Australasia, 38 [4%] from Africa, and four [&l…

Assessment in vitro of radioprotective efficacy of curcumin and resveratrol
2011
Abstract Many natural substances have been studied in recent past to be used as radioprotectors to mitigate ionizing radiation-induced damage in mammalian systems due to its effectiveness given both pre- and post-irradiation and for long time with out drug-related toxicity. Curcumin and trans -resveratrol are both natural occurring polyphenols, obtained from the root of Curcuma longa and from grapes and other berries, respectively. These compounds have shown antioxidant, anti-inflammatory, immunostimulant and anti-carcinogenic properties. Our aim was to evaluate the radioprotective efficacy, in vitro , of curcumin and trans -resveratrol separately against radiation-induced chromosomal aberr…
Conditions in Home and Transplant Soils Have Differential Effects on the Performance of Diploid and Allotetraploid Anthericum Species
2015
Due to increased levels of heterozygosity, polyploids are expected to have a greater ability to adapt to different environments than their diploid ancestors. While this theoretical pattern has been suggested repeatedly, studies comparing adaptability to changing conditions in diploids and polyploids are rare. The aim of the study was to determine the importance of environmental conditions of origin as well as target conditions on performance of two Anthericum species, allotetraploid A. liliago and diploid A. ramosum and to explore whether the two species differ in the ability to adapt to these environmental conditions. Specifically, we performed a common garden experiment using soil from 6 …
A new polyphosphate calcium material with morphogenetic activity
2015
Abstract Polyphosphate [polyP] has been proven to elicit morphogenetic activity on bone cells. By applying mild reaction conditions, a Ca-polyP material that displays a hardness of ≈1.3 GPa has been fabricated. The Ca-polyP granules are prone to hydrolytic degradation during in vitro incubation of the cells, suggesting that this property is associated with the observed bioactivity.
Copper(II)-Binding Induces a Unique Polyproline Type II Helical Structure within the Ion-Binding Segment in the Intrinsically Disordered F-Domain of …
2019
Reproduction of the dominant vector of Zika and dengue diseases, Aedes aegypti mosquito, is controlled by an active heterodimer complex composed of the 20-hydroxyecdysone receptor (EcR) and ultraspiracle protein. Although A. aegypti EcR shares the structural and functional organization with other nuclear receptors, its C-terminus has an additional long F domain (AaFEcR). Recently, we showed that the full length AaFEcR is intrinsically disordered with the ability to specifically bind divalent metal ions. Here, we describe the details of the exhaustive structural and thermodynamic properties of Zn2+- and Cu2+-complexes with the AaFEcR domain, based on peptide models of its two putative metal …
