Broncalt®, class II medical device, in patients with chronic relapsed upper airways disease: a survey in clinical practice.

2019

Inflammation and infection are common pathogenic mechanisms involved in many otorhinolaryngological (ORL) chronic diseases. Broncalt® is a class II Medical Device containing: thermal water (Medesano, PR, Italy), hyaluronic acid, and grapefruit seed extract. It could exert a safe and effective anti-inflammatory, washing, and antimicrobial activity by virtue of these components. Therefore, the aim of the current survey, conducted in clinical practice of 84 Italian ORL centers, was to evaluate its safety and efficacy in the treatment of patients with chronic upper airways disease. The 1,817 (958 males, mean age 49 years) patients were evaluated at baseline (T0) and after one (T1) and two (T2) …

Long-term organic farming on a citrus plantation results in soil organic carbon recovery

2019

[ES] Se ha demostrado que el manejo del suelo bajo agricultura ecológica puede aumentar el contenido de carbono orgánico en el suelo moderando el incremento de los gases de efecto invernadero, pero hasta la fecha las evaluaciones cuantitativas basadas en mediciones a largo plazo han sido escasas, especialmente bajo condiciones mediterráneas. En esta investigación se examinaron los cambios en el contenido de carbono orgánico como respuesta a la agricultura ecológica con cobertura vegetal en una plantación de cítricos en el área mediterránea, utilizando una base de datos de 21 años. El incremento de contenido de carbono orgánico en el suelo fue más evidente tras cinco años desde el cambio del…

Growth of citrus production among the Euro-Mediterranean countries: political implications and empirical findings

2013

The agricultural matter has always played an important role in holding back the Euro-Mediterranean integration process due to the strong complementarity of the agricultures of the coastal countries which share excellent products including citrus fruits. The main goal of this paper is to understand the growth dynamics of the citriculture in the countries bordering the Mediterranean Sea. Through the application of the dynamic formulation of the Shift and Share Analysis it has been possible to analyse the trend of the amount of harvested citrus production, in physical and economic terms, in the last fifteen years, and above all which components, structural and competitive, have mainly influenc…

Protective effect of bioaccessible fractions of citrus fruit pulps against H2O2-induced oxidative stress in Caco-2 cells

2017

Fruit pulps from Navel (N) and Cara Cara (CC) oranges, and Clementine mandarin freshly harvested (M) and refrigerated stored (M12) were used to evaluate the cytoprotective effect of their bioaccessible fractions (BF) against H2O2-induced oxidative stress in Caco-2 cells. BF of samples preserved viability vs. H2O2 treated cells, reaching values similar to controls. Lipid peroxidation was reduced to levels of control cells, but M did not reach control values. ROS and mitochondrial membrane potential changes (Δψm) values were reduced compared with H2O2 treated cells, but without achieving control levels. A significant reduction in cell proportions in G1 phase and a significant increase in sub-…

Determination of the effective emissivity and temperature under vertical observation of a citrus orchard. Application to frost nowcasting

1988

Abstract In this work we use Becker's model for the determination of the effective temperature and emissivity under vertical observation of a citrus orchard. We apply this model to the particular case of a typically radiative night cooling (completely clear sky and calm wind) condition under which radiation frosts are normally produced which are damaging to the fruit and, consequently, to the Valencian economy. An attempt is made to establish a safety limit over which a frost cannot be produced. Ground and orange tree emissivity measurements were carried out by means of the box method. We were able to construct a hand-driven scanning system for the temperature measurement of the ground-oran…

Preliminary evaluation of biopolymers production by mixed microbial culture from citrus wastewater in a MBR system using respirometric techniques

2021

Abstract This preliminary study was aimed at evaluating the feasibility to produce biopolymers (BP) from citrus wastewater by mixed microbial culture in an anaerobic/aerobic membrane bioreactor (A/O-MBR). The activated sludge of the A/O-MBR was successfully enriched in microorganisms having a good capacity in producing intracellular biopolymers. The production of BP was found to be about 0.55 mgCOD mgCOD−1 using pure acetate at a concentration of 1000 mgCOD L−1. When using fermented wastewater, the conversion of acetate into BP product was 0.56 mgCOD mgCOD−1 in the test performed with C/N equal to 1000:1, whereas it was only 0.12 mgCOD mgCOD−1 in the test with C/N of 100:5. The results achi…

In vitro anther culture of sweet orange (Citrus sinensis L. Osbeck) genotypes and of a C. clementina × C. sinensis 'Hamlin' hybrid

2014

Citrus, and particularly sweet oranges, are very recalcitrant to anther culture. In this paper it was evaluated for the first time the response of 27 genotypes of Citrus sinensis and of one hybrid C. clementina × C. sinensis, to in vitro anther culture. Ten genotypes of sweet oranges showed embryogenic callus induction, mostly blood sweet oranges genotypes, such as Tarocco, Moro and Sanguinelli. In vitro microspore developmental switches from the gamethophytic to the sporophytic pathway were shown by DAPI staining in microspores of these responsive genotypes, after 10 months in culture. However, microsatellite marker analyses showed that these calli were heterozygous. The flow-cytometric an…
