Celiac Disease, Inflammation and Oxidative Damage: A Nutrigenetic Approach

Abstract: Celiac disease (CD), a common heritable chronic inflammatory condition of the small intestine caused by permanent intolerance to gluten/gliadin (prolamin), is characterized by a complex interplay between genetic and environmental factors. Developments in proteomics have provided an important contribution to the understanding of the biochemical and immunological aspects of the disease and the mechanisms involved in toxicity of prolamins. It has been demonstrated that some gliadin peptides resistant to complete proteolytic digestion may directly affect intestinal cell structure and functions by modulating gene expression and oxidative stress. In recent years, the creation of the two research fields Nutrigenomics and Nutrigenetics, has enabled the elucidation of some interactions between diet, nutrients and genes. Various dietary components including long chain ω-3 fatty acids, plant flavonoids, and carotenoids have been demonstrated to modulate oxidative stress, gene expression and production of inflammatory mediators. Therefore their adoption could preserve intestinal barrier integrity, play a protective role against toxicity of gliadin peptides and have a role in nutritional therapy of celiac disease.

Yeast interactions in multi-starter wine fermentation

Abstract: Spontaneous fermentation of grape juice is driven by a complex community of microorganisms, although diffusion of the use of selected strains of Saccharomyces cerevisiae has lead to the simplification of microbial communities in the fermentation process. More recently, there has been a growing interest towards controlled mixed fermentations that use more than one selected yeast strain. This thus aims to improve specific traits, or in general to enhance the complexity and particular characteristics of the resulting wines. In this context, yeast interactions have a fundamental role to obtain the desired product characteristics. These interactions can affect the metabolite production and/or the microbial growth. To control and optimise complex mixed fermentation, further knowledge of both of these aspects is needed.

Environmental Impact Assessment of Hydrometallurgical Processes for Metal Recovery from WEEE Residues Using a Portable Prototype Plant

Abstract: Life cycle assessment (LCA) was applied to hydrometallurgical treatments carried out using a new portable prototype plant for the recovery of valuable metals from waste electrical and electronic equipment (WEEE). The plant was fed with the WEEE residues from physical processes for the recycling of fluorescent lamps, cathode ray tubes (CRTs), Li-ion accumulators and printed circuit boards (PCBs). Leaching with sulfuric acid was carried out, followed by metal recovery by selective precipitation. A final step of wastewater treatment with lime was performed. The recovered metals included yttrium, zinc, cobalt, lithium, copper, gold, and silver. The category of global warming potential was the most critical one considering the specifications for southern European territories, with 13.3 kg CO(2)/kg recovered metal from the powders/residues from fluorescent lamps, 19.2 kg CO(2)/kg from CRTs, 27.0 kg CO(2)/kg from Li-ion accumulators and 25.9 kg CO(2)/kg from PCBs. Data also show that metal extraction steps have the highest load for the environment. In general, these processes appear beneficial for the environment in terms of CO(2) emissions, especially for metal recovery from WEEE residues from fluorescent lamps and CRTs.
