Case report: Multicomponent intervention for severe food selectivity in autism spectrum disorder: a single case study.

Food selectivity is common in children with Autism Spectrum Disorder (ASD). The treatment used can be invasive and difficult to implement, necessitating the exploration of multicomponent approaches. This study presents the case of a 9-year-old autistic girl with severe food selectivity, who ate exclusively liquid and semi-solid foods.

Use of Hazelnut Perisperm as an Antioxidant for Production of Sustainable Biodegradable Active Films.

Utilization of food-waste-derived bioactive compounds with biodegradable polymers is an attractive strategy leading innovation in the food packaging sector and contributing to reduce the environmental concerns of plastic packaging disposal. In this field, this work is aimed to use hazelnut perisperm as an antioxidant agent in the production of biodegradable polymeric films for active packaging applications. For this purpose, hazelnut perisperm of a selected particle size (<250 μm) at different percentages (0%, 5% and 10% by weight) was added to a bioderived and compostable polymer suitable for food contact, known as Ecovio®.

Relative preferences for edible and leisure stimuli in children with autism: A replication in Italy.

Several studies have found that edible items tend to displace leisure items in multiple-stimulus preference assessments for individuals with developmental disabilities. One recent study (Conine & Vollmer, 2019) included screen-based technology devices in assessments and found that food items were less likely to displace leisure items and in some cases leisure items totally displaced edible items. The purpose of our study was to conduct a replication of Conine and Vollmer in Italy to evaluate cultural differences in food and leisure preferences.

When Speech Stops, Gesture Stops: Evidence From Developmental and Crosslinguistic Comparisons.

There is plenty of evidence that speech and gesture form a tightly integrated system, as reflected in parallelisms in language production, comprehension, and development (McNeill, 1992; Kendon, 2004). Yet, it is a common assumption that speakers use gestures to compensate for their expressive difficulties, a notion found in developmental studies of both first and second language acquisition, and in theoretical proposals concerning the gesture-speech relationship. If gestures are compensatory, they should mainly occur in disfluent stretches of speech.

Explorative genetic association study of GSTT2B copy number variant in complex disease risks.

Background: Glutathione S-transferases (GSTs) are the main phase II enzymes involved in cellular detoxification. Through phase I and phase II detoxification reactions, the cell is able to detoxify endogenous and exogenous toxic compounds.

Aims: This study focused attention on the GSTT2B copy number variant (CNV) in order to explore its involvement in the genetic pre-disposition to asthma, Alzheimer's disease (AD), allergic rhinitis (AR), essential hypertension (EH), hypothyroidism and recurrent miscarriage (RM).

GSTO1 uncommon genetic variants are associated with recurrent miscarriage risk.

Objective: To explore the role of the GSTO1 gene in the pathogenesis of recurrent miscarriage (RM).

Design: Genetic association study.

Setting: Rome, Italy.

Long-term cryopreservation of dental pulp stem cells (SBP-DPSCs) and their differentiated osteoblasts: a cell source for tissue repair.

It is not known whether cells derived from stem cells retain their differentiation and morpho-functional properties after long-term cryopreservation. This information is of importance to evaluate their potential for long-term storage with a view to subsequent use in therapy. Here, we describe the morpho-functional properties of dental pulp stem cells (SBP-DPSCs), and of their differentiated osteoblasts, recovered after long-term cryopreservation.

Sensitized photooxygenation of the fungicide furalaxyl.

Background: The photolysis of pesticides is of high current interest since light is one of the most important abiotic factors which are responsible for the environmental fate of these substances and may induce their conversion into noxious products. The action of light can also be mediated by oxygen and synthetic or naturally occurring substances which act as sensitizers. Our objective in this study was to investigate the photochemical behaviour of the systemic fungicide furalaxyl in the presence of oxygen and various sensitizers, and to compare the toxicity of the main photoproduct(s) to that of the parent compound.

Effects of sensitizers on the photodegradation of the systemic fungicide triadimenol.

The photochemical behaviour of triadimenol (1) under various conditions has been examined. Significant degradation is obtained only in the presence of electron-acceptor sensitizers as 9,10-dicyanoanthracene or 2,4,6-triphenylpyrylium tetrafluoroborate, and long irradiation times are required. 1H-1,2,4-Triazole (2), 4-chlorophenyl formate (3), 4-chlorophenol (4), 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-one (5), 4-chlorophenyl 2,2-dimethylpropanoate (6) and 4-chlorobenzoic acid (7) were identified as photoproducts by NMR and GC-MS.

Impaired temperature stress response of a Streptococcus thermophilus deoD mutant.

An insertional deoD mutant of Streptococcus thermophilus strain SFi39 had a reduced growth rate at 20 degrees C and an enhanced survival capacity to heat shock compared to the wild type, indicating that the deoD product is involved in temperature shock adaptation. We report evidence that ppGpp is implicated in this dual response.

Photochemical behaviour of the systemic fungicide carboxin.

Irradiation of carboxin (1) with a 500 W UV lamp (filter Pyrex) in CH3CN leads to the products 3, 5-8, 12-14 depending upon the reaction conditions. All photo-products were isolated and characterized. Photooxidation occurred even if unsensitized, while photoalteration was very slow in the absence of oxygen.
