Diabetes and renin-angiotensin-aldosterone system: Implications for covid-19 patients with diabetes treatment management
2020
In the context of the COVID-19 continuous spreading, this paper focuses on the increased risk of diabetic patients regarding the metabolic control and the uncertainties related to SARS-CoV-2 infection. Chronic hyperglycaemia negatively affects the immune system, which triggers an increase of morbidity and mortality for viral infections. A key aspect of COVID-19 resides in the involvement of renin-angiotensin-aldosterone (RAAS) system that causes a cascade of reactions mediated by vasoactive peptides with implications in vasoconstriction, vascular permeability, oxidative stress remodelling and tissue injuries. Activation of RAAS at pulmonary level, is responsible for the local damage. Many q…
Carotenoids and Some Other Pigments from Fungi and Yeasts †
2021
Carotenoids are an essential group of compounds that may be obtained by microbiological synthesis. They are instrumental in various areas of industry, medicine, agriculture, and ecology. The increase of carotenoids’ demand at the global market is now essential. At the moment, the production of natural carotenoids is more expensive than obtaining their synthetic forms, but several new approaches/directions on how to decrease this difference were developed during the last decades. This review briefly describes the information accumulated until now about the beneficial effects of carotenoids on human health protection, their possible application in the treatments of various diseases, and their…
Post-harvest Industrial Processes of Almond (Prunus dulcis L. Mill) in Sicily Influence the Nutraceutical Properties of By-Products at Harvest and Du…
2021
Almond cultivation in Sicily is experiencing a phase of great interest which is mainly concentrated in the development of specialized orchards, with irrigation and by adopting cultivars with high qualitative and quantitative performances. These are mostly Mediterranean genotypes with high fat content and hard or semi-hard shell, extremely different from the varieties of Californian diffusion. The development of the sector comprises the primary production of almonds but also a series of secondary products which often represent a burden for the company. From these considerations several researches have been developed with the aim of giving a value to these by-products through circular economy…
Dynamics of Monoterpene Formation in Spike Lavender Plants
2017
The metabolic cross-talk between the mevalonate (MVA) and the methylerythritol phosphate (MEP) pathways was analyzed in spike lavender (Lavandula latifolia Med) on the basis of 13CO2-labelling experiments using wildtype and transgenic plants overexpressing the 3-hydroxy-3-methylglutaryl CoA reductase (HMGR), the first and key enzyme of the MVA pathway. The plants were labelled in the presence of 13CO2 in a gas chamber for controlled pulse and chase periods of time. GC/MS and NMR analysis of 1,8-cineole and camphor, the major monoterpenes present in their essential oil, indicated that the C5-precursors, isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) of both monoterpenes …
Innovative Alcoholic Drinks Obtained by Co-Fermenting Grape Must and Fruit Juice
2019
In this study, Cabernet Sauvignon and Chardonnay musts, and fruit juices from cherry, kiwi, peach, and strawberry were co-fermented with Saccharomyces cerevisiae EC1118 and Torulaspora delbrueckii UMY196 at two different proportions (80:20 (v/v) and 60:40 (v/v)). The most pleasant fruit-based drink was obtained with Cabernet Sauvignon must and kiwi juice in a proportion of 60:40 and fermented with T. delbrueckii. This beverage was produced in higher volume to simulate a scale-up, and the aromatic profile, sensory description, and consumer acceptability were determined. The most powerful odorants of the kiwi-based drink were ethyl octanoate, phenylethanal, ethyl hexanoate, vinyl-guaiacol, be…
Diferencias en las características clínico-biológicas y prevalencia de complicaciones crónicas en relación con el envejecimiento de pacientes con dia…
2016
Resumen La diabetes tipo 2 (DMT2) es una enfermedad con elevada prevalencia que aumenta con la edad. Por este motivo y por sus complicaciones cronicas genera elevado coste humano, social y economico en la poblacion mayor. Ademas, la poblacion mayor con DMT2 presenta una marcada heterogeneidad clinica. Por lo que nuestro objetivo principal es conocer como se relaciona la edad con el fenotipo clinico-biologico y cual es la prevalencia de complicaciones cronicas en el paciente con DMT2. Material y metodos Estudio transversal de una amplia poblacion de DMT2 (n = 405) seleccionada de forma aleatoria de una Unidad de Diabetes y 2 centros de salud (60%). En estos sujetos se recogieron variables cl…
CO-74: Altérations majeures du sphingophospholipidome des lipoprotéines de haute densité (HDL) de patients avec syndrome métabolique et glycémie norm…
2016
Rationnel Les phospholipides et sphingolipides jouent un role primordial dans la fonctionnalite et le role anti-atherogene des HDL. Ces proprietes sont alterees chez les patients porteurs d'un syndrome metabolique avant meme l'apparition d'une hyperglycemie. Nous avons donc recherche si les HDL de ces patients presentaient des anomalies de leur sphingophospholipidome. Patients et Methodes Par chromatographie liquide couplee a la spectrometrie de masse en tandem, nous avons quantifie 80 especes moleculaires des principales classes de phospholipides et sphingolipides des HDL2 et HDL3, chez 26 patients avec un syndrome metabolique et une glycemie a jeun nor-male (14 hommes, 12 femmes, âge moye…

Bénéfices cardiovasculaires et rénaux des inhibiteurs de SGLT2 : mécanismes de la protection
2019
Resume Les inhibiteurs de SGLT2 ont montre, dans plusieurs etudes prospectives, leur benefice cardiovasculaire et renal avec, plus particulierement, une diminution rapide et tres significative des hospitalisations pour insuffisance cardiaque et des evenements renaux severes : doublement de la creatinine ou recours a l’epuration extra-renale. Le lien fort entre la physiopathologie de l’insuffisance cardiaque et renale explique l’analyse commune des hypotheses de protection de cette classe medicamenteuse. Les mecanismes precis rendant compte de l’amelioration de la fonction myocardique et renale sous inhibiteurs de SGLT2 ne sont pas encore eclaircis, mais plusieurs hypotheses peuvent etre ava…
Un parcours de soins primaires pour améliorer la prise en charge et le pronostic des patients diabétiques avec une plaie de pied
2021
Resume Introduction Les plaies de pied diabetique (PPD) sont un probleme frequent, associe a un risque eleve d’amputation et de mortalite. L’adressage rapide a une structure specialisee du pied diabetique permet d’ameliorer le taux de cicatrisation et de diminuer le risque d’amputation. Une proportion importante de patients avec une PPD sont adresses tardivement vers ces structures specialisees. Un parcours de soins primaires des patients avec une PPD a ete developpe par l’International Diabetic Foot Care Group en collaboration avec le D-Foot International pour ameliorer l’orientation de ces patients vers les structures specialisees. Nous presentons une version adaptee au systeme de soin fr…
