Evaluation of the effects of chitosan films as a replacement for conventional sulphur dioxide treatment of white wines

ABSTRACT: In this study, 1H-NMR metabolomics was used to evaluate the effects of using chitosan-genipin (Ch-Ge) films as replacement of sulfur dioxide (SO2) in white wines preservation, to circumvent adverse health consequences caused by SO2 intake, on the final compositional profile of white wines. To do so, differently sized Ch-Ge films (25 and 100 cm2) were tested, as well as SO2-tretment and untreated wines. The obtained data added important knowledge on the potential use of Ch-Ge films, particularly those of higher surface areas, as replacements for the use of SO2 in wine conservation, based on the changes noted in metabolite composition and their putative explanations in terms of wine chemical and biochemical characteristics.

Project description:Vascular cognitive impairment and dementia (VCID) is the second most common form of dementia after Alzheimer’s disease (AD). Currently, the mechanistic insights into the evolution and progression of VCID remain elusive. White matter change represents an invariant feature. Compelling clinical neuroimaging and pathological evidence suggest a link between white matter changes and neurodegeneration. Our prior study detected hypoperfused lesions in mice with partial deficiency of endothelial nitric oxide (eNOS) at very young age, precisely matching to those hypoperfused areas identified in preclinical AD patients. White matter tracts are particularly susceptible to the vascular damage induced by chronic hypoperfusion. Using immunohistochemistry, we detected severe demyelination in the middle aged eNOS-deficient mice. The demyelinated areas were confined to cortical and subcortical areas including the corpus callosum and hippocampus. The intensity of demyelination correlated with behavioral deficits of gait and associative recognition memory performances. By Evans blue angiography, we detected blood-brain barrier (BBB) leakage as another early pathological change affecting frontal and parietal cortex in eNOS-deficient mic. Sodium nitrate fortified drinking water provided to young and middle aged eNOS-deficient mice completely prevented non-perfusion, BBB leakage, and white matter pathology, indicating that impaired endothelium-derived NO signaling may have caused these pathological events. Furthermore, genome-wide transcriptomic analysis revealed altered gene clusters most related to mitochondrial respiratory pathways selectively in the white matter of young eNOS-deficient mice. Using eNOS-deficient mice, we identified BBB breakdown and hypoperfusion as the two earliest pathological events, resulting from insufficient vascular NO signaling. We speculate that the compromised BBB and mild chronic hypoperfusion trigger vascular damage, along with oxidative stress and astrogliosis, accounting for the white matter pathological changes in the eNOS-deficient mouse model. We conclude that eNOS-deficient mice represent an ideal spontaneous evolving model for studying the earliest events leading to spontaneous white matter changes, which will be instrumental to future therapeutic testing of drug candidates and for targeting novel/specific vascular mechanisms contributing to VCID and AD.
