Determination of Fungi and Multi-Class Mycotoxins in Camelia sinensis and Herbal Teas and Dietary Exposure Assessment
2020
In this paper, a study of fungal and multi-mycotoxin contamination in 140 Camellia sinensis and 26 herbal teas marketed in Latvia is discussed. The analysis was performed using two-dimensional liquid chromatography with time-of-flight mass spectrometry (2D-LC-TOF-MS) and MALDI-TOF-MS. In total, 87% of the tea samples tested positive for 32 fungal species belonging to 17 genera, with the total enumeration of moulds ranging between 1.00 ×
Morphological and biometrical features of Trypanosoma evansi isolates from an outbreak in mainland Spain.
2011
According to several authors, Trypanosoma evansi is a monomorphic trypanosome found exclusively in slender intermediate forms, although additional studies have revealed that many strains present stumpy forms on rare occasions. In a recent T. evansi outbreak in mainland Spain, several atypical forms were observed in blood smear examinations. Molecular procedures were then necessary to confirm the causal agent. Morphological and biometric measures were taken to characterize the different forms of T. evansi. In contrast to published information, the results of this study would indicate that biometrically distinct T. evansi could also be found in the same farm and even in the same animal specie…
Inhibition of Folic Acid Uptake by Catechins and Tea Extracts in Caco-2 Cells
2006
In this present study it was aimed to determine whether the catechins contained in green tea and the whole extracts of Camellia sinensis (Theaceae) inhibit the uptake of folic acid by Caco-2 cell monolayers. Our results indicate that (-)-epigallocatechin 3-gallate (EGCG) and (-)-epicatechin 3-gallate (ECG) inhibit cellular folic acid uptake with IC50 values of 34.8 micromol/L and 30.8 micromol/L, respectively. Furthermore, green and black tea extracts were also found to inhibit folic acid uptake with IC50 values of approximately 7.5 and 3.6 mg/mL, respectively. According to these results, simultaneous intake of tea and folic acid may inhibit intestinal folic acid absorption. The consequence…
The foaming properties of camel and bovine whey: The impact of pH and heat treatment
2018
International audience; he effect of heat treatment (70 degrees C or 90 degrees C for 30 min) on the foaming and interfacial properties of acid and sweet whey obtained from bovine and camel fresh milk was examined. The maximum foamability and foam stability were observed for acid whey when compared to sweet whey for both milks, with higher values for the camel whey. This behavior for acid whey was explained by the proximity of the pI of whey protein (4.9-5.2), where proteins were found to carry the lowest negative charge as confirmed by the zeta potential measurements. Interfacial properties of acid camel whey and acid bovine whey were preserved at air water interface even after a heat trea…
An inter-laboratory comparison to evaluate the suitability of EN 1787 standard to detect irradiation in plant-origin foods with health benefits
2020
Abstract This paper reports the results of a study carried out to verify the applicability of the EN 1787 method, which uses the Electron Spin Resonance (ESR) technique for the identification of irradiated plant-origin foods with health benefits. The method was tested on samples of herbal ingredients of Plant Food Supplements (PFSs), nuts and fresh blueberries. Untreated and irradiated samples of Camellia sinensis (leaves) Ginkgo biloba (leaves), Glycine max (seeds), Silybum marianum (fruits), Vaccinium myrtillus (fruits), almonds, hazelnuts, peanuts, pistachios, walnuts and fresh blueberries were analysed. The work includes an inter-laboratory blind test involving five Italian laboratories…
Risk management in the banking industry
2016
El negocio bancario está altamente regulado porque las instituciones financieras captan ahorro público y tienen riesgos específicos y complejidades que hacen que sus estados financieros sean opacos y difíciles de analizar por el público en general (Petrella y Resti, 2013; Morgan, 2001). Para entender y monitorear los riesgos específicos en las empresas del sector financiero, el regulador estadounidense diseñó el sistema de evaluación CAMELS, que es comúnmente utilizado por los reguladores de todo el mundo para evaluar la solidez de las instituciones financieras y para evaluar el nivel de riesgo de los bancos (Office of the Comptroller of the Currency, 2013). Los riesgos que este enfoque eva…
Trypanosoma evansi infection in mainland Spain.
2009
An outbreak of Trypanosoma evansi infection that occurred in mainland Spain is described. The outbreak occurred on an equine and camel farm to which dromedary camels from an infected area of the Canary Islands had recently been introduced. One of these camels developed clinical signs and T. evansi was discovered in a blood smear examination. The herd was evaluated in order to determine the extent of the disease. The results showed that 76% of the camels, 35% of the donkeys and 2% of the horses were affected. The animals were isolated and treated using Cymelarsan((R)) (0.5mg/kg). After treatment, three blood analysis using parasitological methods revealed negative results. This is the first …
La fauna indoeuropea. Sobre els noms del llop i el camell en ie.
2015
Els noms d’animals salvatges i domèstics ocupen un lloc principal en tots els estudis sobre vocabulari, cultura o economia dels indoeuropeus. La seua reconstrucció serveix com a il·lustració molt aclaridora d’un poble que passa de ser nòmada a sedentari i que, probablement fugint d’una climatologia extrema, protagonitza una gran expansió cap a indrets més temperats i fèrtils on descobreix i estén la ramaderia i l’agricultura. En aquest treball farem un breu repàs a la nòmina tradicionalment acceptada d’animals del món indoeuropeu i en revisarem l’etimologia de dos d’ells: el llop, prototip d’animal ferotge en totes les cultures indoeuropees (lupus est homo hominis), i el camell, oblidat en …
The role of light in the emergence of weeds: using Camelina microcarpa as an example
2015
When modelling the emergence of weeds, two main factors are considered that condition this process: temperature and soil moisture. Optimum temperature is necessary for metabolic processes that generate energy for growth, while turgor pressure is necessary for root and shoot elongation which eventually leads to seedling emergence from the soil. Most emergence models do not usually consider light as a residual factor, but it could have an important role as it can alter directly or indirectly the dormancy and germination of seeds. In this paper, inclusion of light as an additional factor to photoperiod and radiation in emergence models is explored and compared with the classical hydrothermal t…
