Suspected Nonceliac Gluten Sensitivity Confirmed in Few Patients After Gluten Challenge in Double-Blind, Placebo-Controlled Trials

2017

A double-blind, placebo-controlled, gluten challenge has been proposed to confirm a diagnosis of non-celiac gluten sensitivity (NCGS) in patients without celiac disease who respond to a gluten-free diet. To determine the accuracy of this approach, we analyzed data from 10 double-blind, placebo-controlled, gluten challenge trials, comprising 1312 adults. The studies varied in the duration of the challenge (ranging from 1 day to 6 weeks), daily doses for the gluten challenge (ranging from 2 g to 52 g; 3 studies administered less than 8 g/day), and composition of the placebo (gluten-free products, xylose, whey protein, rice, or corn starch containing fermentable carbohydrates). Most of the stu…

Le varietà di grano duro per le semine 2020: Sicilia

2020

Nonostante le difficoltà operative dovute alla pandemia da Covid-19, anche nel corso del 2019-20 sono state condotte in Sicilia le prove di confronto varietale di frumento duro, allestite in 5 località della Sicilia: Libertinia (Catania), Catania, S. Stefano Quisquina (Agrigento), Caltagirone (Catania) e Ciminna (Palermo). La sperimentazione ha riguardato 30 varietà, di cui 5 al primo anno di valutazione, 9 cultivar al secondo anno di prova e 16 genotipi testati da oltre due anni. La resa media dell’areale siciliano è stata pari a 6,11 t/ha e i risultati produttivi registrati nei diversi ambienti di prova appaiono sensibilmente influenzati dall’andamento termo-pluviometrico. Despite the dif…

The spatial and temporal distribution of carabid and weed seed predation in winter wheat: a comparison between conventional and conservation agricult…

2013

Carabids can be key players in weed seed predation within arable crops under temperate climate. Field management options, because they affect carabid communities, may represent potential levers to increase weed seed predation levels within fields. Among these options, Conservation Agriculture is often presented as a promising management option for carabids but its effect on weed seed predation levels is less clear. In this study, carabids and weed seed predation were monitored using a grid sampling from April till September 2011 in two adjacent winter-wheat fields in North-eastern France, one conducted as no-till with cover crop for 5 years (conservation agriculture) and the other as conven…

Pesticides sur blé tendre d'hiver, diversité dans le détail

2013

Contexte -L’analyse des pratiques d’application des pesticides (herbicides, fongicides, insecticides, ré-gulateurs) sur le blé tendre d’hiver (BTH) a été réalisée à partir de données d’en-quêtes annuelles sur une petite zone agricole en Côte-d’Or. Etude - L’étude a porté sur 294 parcelles appar-tenant à 13 exploitants pour la période 2004-2011. L’indice retenu pour carac-tériser l’usage des pesti-cides est l’IFT (indice de fréquence de traitements).

The Overlapping Area of Non-Celiac Gluten Sensitivity (NCGS) and Wheat-Sensitive Irritable Bowel Syndrome (IBS): An Update

2017

Gluten-related disorders have recently been reclassified with an emerging scientific literature supporting the concept of non-celiac gluten sensitivity (NCGS). New research has specifically addressed prevalence, immune mechanisms, the recognition of non-immunoglobulin E (non-IgE) wheat allergy and overlap of NCGS with irritable bowel syndrome (IBS)-type symptoms. This review article will provide clinicians with an update that directly impacts on the management of a subgroup of their IBS patients whose symptoms are triggered by wheat ingestion.

Amino acid profile of four varieties of durum wheat grown in Sicily

2015

The major use of durum wheat is for pasta products, particularly in the European and North American countries, whereas in other areas (Middle East and North Africa) also it is used as couscous and for various types of bread. The durum wheat is therefore a staple food in the Mediterranean and is one of the commodities that characterize the dietary pattern of the Mediterranean diet. During the year 2012 were made in Ciminna (Palermo) in Sicily, four fields of experimental cultivation using four different varieties of durum wheat cultivated in Sicily: Simeto, Iride, Duilio and Saragolla. For each variety were set up two different kinds of cultivation tecniques, in order to verify the influence…

Behaviour of the herbicide EL-107 in wheat and rape grown under controlled conditions

1987

Summary The behaviour of 14C-EL-107 has been evaluated in winter wheat and rape, which are tolerant and susceptible, respectively, under field conditions. After 10- to 13-days’growth under controlled conditions, seedlings were allowed to absorb the herbicide through the roots. Two experiments were conducted to study the absorption and the metabolism of EL-107. Absorption was estimated during a 5-day treatment at the rate of 1–47 μM, and metabolism was studied after a 1-day treatment at 14.7 μM. The results showed that (i) rape plants absorbed more herbicide than wheat, and translocated less radioactivity into their shoots, and (ii) the metabolism of EL-107 proceeded actively only in the sho…

Iron-loaded transferrin (Tf) is detrimental whereas iron-free Tf confers protection against brain ischemia by modifying blood Tf saturation and subse…

2018

Despite transferrin being the main circulating carrier of iron in body fluids, and iron overload conditions being known to worsen stroke outcome through reactive oxygen species (ROS)-induced damage, the contribution of blood transferrin saturation (TSAT) to stroke brain damage is unknown. The objective of this study was to obtain evidence on whether TSAT determines the impact of experimental ischemic stroke on brain damage and whether iron-free transferrin (apotransferrin, ATf)-induced reduction of TSAT is neuroprotective. We found that experimental ischemic stroke promoted an early extravasation of circulating iron-loaded transferrin (holotransferrin, HTf) to the ischemic brain parenchyma.…

Microbial dynamics in durum wheat kernels during aging

2020

In the present work the microbial dynamics in wheat kernels were evaluated over time. The main aim of this research was to study the resistance of lactic acid bacteria (LAB) and yeasts associated to unprocessed cereals used for bread making during long term conservation. To this purpose four Triticum durum Desf. genotypes including two modern varieties (Claudio and Simeto) and two Sicilian wheat landraces (Russello and Timilia) were analysed by a combined culture-independent and -dependent microbiological approach after one, two or three years from cultivation and threshing. DNA based MiSeq Illumina technology was applied to reveal the entire bacterial composition of all semolina samples. T…
