Determination of Fusarium mycotoxins enniatins, beauvericin and fusaproliferin in cereals and derived products from Tunisia

2011

Abstract In this study, 51 samples of cereals (wheat, Barley, maize and Sorghum) and by-products (mainly pasta and couscous) purchased from Tunisian supermarkets were examined for contamination with the emerging Fusarium mycotoxins: Enniatins ENs (EN A, EN A 1 , EN B and EN B 1 ), beauvericin (BEA) and fusaproliferin (FUS). The extraction of the samples was performed with methanol using an Ultra-turrax homogenizer. Mycotoxins were analyzed with a liquid chromatography (LC) coupled to a diode array detector (DAD). The frequencies of contamination of total samples with ENs were 96%. EN A 1 was the most common EN found with the highest prevalence of 92.1%, levels ranged between 11.1 and 480 mg…

First report on the presence of emerging Fusarium mycotoxins enniatins (A, A1, B, B1), beauvericin and fusaproliferin in rice on the Moroccan retail …

2011

Seventy samples of rice purchased from local markets in six cities from Morocco (Rabat, Casablanca, Kenitra, Mohammadia, Tanger and Errachidia) were analyzed for the presence of six emerging mycotoxins: four enniatins ENs (ENA, ENA1, ENB and ENB1), beauvericin (BEA) and fusaproliferin (FUS). Samples were extracted with a mixture of acetonitrile/water (85/15, v/v) by using an ultra-turrax homogenizer. Mycotoxins were then identified and quantified with liquid chromatography (LC) coupled to diode array detector (DAD). Positive samples were confirmed with an LC-MS/MS. Analytical results showed that BEA was present in 75.7% of total analyzed samples. BEA levels varied between 3.8 and 26.3 mg/kg…

Abstract In this study, 64 samples of raw cereals (wheat, maize and barley) purchased from local markets in Rabat–Sale area from Morocco were analyzed for the occurrence of six emerging mycotoxins: four enniatins ENs (ENA, ENA1, ENB and ENB1), beauvericin (BEA) and fusaproliferin (FUS). Samples were extracted with a mixture of water/acetonitrile (85/15, v/v) by using an Ultra-turrax homogenizer. Mycotoxins were then identified and quantified with a liquid chromatography (LC) with diode array detector (DAD). Positive samples were confirmed with an LC–MS/MS. Analytical results showed that the frequencies of contamination of total samples with ENs, BEA and FUS were 50, 26.5 and 7.8%, respectiv…

Gastric emptying in infants with gastroesophageal reflux Ultrasound evaluation before and after cisapride administration

1992

The present study aimed to evaluate gastric emptying in children with gastroesophageal reflux (GER) by means of real-time ultrasonography, on the basis of measurements of the cross-sectional area of the gastric antrum. Twelve children with GER were studied (seven males, five females; age range, 3-13 months) and compared with 12 normal control children (six males, six females; age range, 3-13 months). The diagnosis of GER was confirmed by 24-h esophageal pH-monitoring. The GER patients had a significantly greater antral area than the controls at 90, 105, and 120 min aftereating a standard meal (cow's milk formula, 300 ml/m2 body surface area); in addition, final gastric emptying time was sig…

Headspace Volatile Composition of the Flowers of Caralluma europaea N.E.Br. (Apocynaceae)

2009

The volatile constituents of the flowers of Caralluma (Apteranthes) europaea (Guss.) N.E. Br. (Apocynaceae - Asclepiadoideae) from Lampedusa Island were analyzed by headspace method. The analyses allowed the identification and quantification of 41 compounds. The main components were, among the monoterpenoids, terpinolene (23.3%), a-terpinene (19.1%) and linalool (18.4%), whereas, among the carbonylic compounds the major constituents were heptanal (2.0%), octanoic acid (2.4%) and hexanoic acid (1.7%). It is worth to mention the presence of a nitrogen containing compound, indole (0.8%) and of a sulphur containing compound, dimethylsulphide (t). The compounds found in the flowers of C. europea…

Bībeles intertekstualitāte Migela de Unamuno romānā “Svētais Manuēls Labais Moceklis”

2018

Šis darbs ir veltīts Migeļa de Unamuno (Miguel de Unamuno) Bībeles intertekstuālu atsauču (tiešu, netiešu) izpētei Migeļa de Unamuno (Miguel de Unamuno) romānā: “Svētais Manuēls Labais moceklis” Pētījumā ir četras nodaļas, kas veido divas daļas: pirmā teorētiskā, kas sastāv no trijām pirmajām nodaļām un definē intertekstualitātes konceptu, parāda Unamuno dzīvi un darbu, īpaši romānu "Svētais Manuēls Labais moceklis". Otrā ir praktiskā daļa, kas sastāv no ceturtās nodaļas, tās mērķis ir atklāt un klasificēt bībliskās intertekstualitātes romānā. Galvenā uzmanība teorētiskajā daļā tiks pievērsta Džulijas Kristeva (Julia Kristeva) un Žerarda Ženeta (Gerard Genette) pētījumiem par to, kā viņi in…

Stable isotopic composition of three foraminifera species in ODP Hole 160-963D

2020

Carbon-rich layers exist at both sides of the Mediterranean Sea sedimentary record and are called sapropels and organic rich layers (ORLs), respectively in the eastern and western basins. They have different levels of organic carbon accumulation and seafloor oxygen deprivation. The most recent sapropel and ORL deposition have a different timing, 10.8-6.1 and 14.5-9.0 ka respectively. Here we investigate oxygen isotopic records of three foraminifera species that occupy different habitats within the Sicily Channel water column since ~ 12.0 ka, thus in the sill between the eastern and western Mediterranean basins. These data are ice volume-corrected, to get information on water masses density …

Surface hydrographic changes at the western flank of the sicily channel associated with the last sapropel

2021

Abstract In the eastern Mediterranean Sea, the early Holocene was characterized by major climatic and oceanographic changes that led to the formation of the last sapropel (S1) between 10.8 and 6.1 kyr cal. BP. These hydrographic changes might have altered the water exchange between the eastern and western Mediterranean sub-basins through the Strait of Sicily, but the existing evidences are inconclusive. In the present study we show new evidence from sediment core NDT-6-2016 located at the western flank of the Sicily channel, a key location to monitor the surface/intermediate water exchange between the two Mediterranean sub-basins. We perform paleo-hydrographic reconstructions based on plank…
