Costituenti bioattivi degli alimenti di origine vegetale

2019

La parola «nutraceutica» è la crasi, non solo semantica, tra i termini nutrienti e farmaceutica, e la disciplina corrispondente richiede la conoscenza di aspetti chimici e biologici, oltre a mostrare che tipo di declinazione ha impresso alla chimica degli alimenti. A partire dal 1990 infatti, anno in cui si è tenuto in Italia il primo Congresso nazionale di Chimica degli alimenti, l'attenzione in questo campo ha cominciato a orientarsi verso la presenza di contaminanti organici e inorganici nei cibi, di metaboliti secondari e di microcostituenti di interesse nutraceutico e salutistico. Da allora sono stati fatti molti passi avanti e questo settore si è rivelato strategico dal punto di vista…

Single-Center-Single-Blinded Clinical Trial to Evaluate the Efficacy of a Nutraceutical Containing Boswellia Serrata, Bromelain, Zinc, Magnesium, Hon…

2022

Some nutraceuticals have been studied as supportive treatment for fighting upper respiratory tract infection and middle ear disease. Our study aims at evaluating the effect of a specific oral supplementation in the treatment of pediatric otits media. The subjects were randomly assigned by the physician (single-blinded study) to one of three groups: Control Group (CG), Treatment Group 1 (TG1), or Treatment Group 2 (TG2). Both TG were treated with Flogostop Duo (for 20 days—TG1 or 30 days—TG2) in combination with the standard treatment, while CG underwent standard treatment only. The standard treatment was nasal aerosol with Fluticasone and Mucolytic, and nasal washing with hypertonic solutio…

The Nutraceutical Properties of Rhus coriaria Linn: Potential Application on Human Health and Aging Biomedicine

2023

Rhus coriaria Linn is a little plant growing in the Mediterranean basin, including Sicily, where it is known as Sicilian Sumac. Since antiquity, it has been used as a medicinal herb, considering its pharmacological properties and its recognized anti-inflammatory, antioxidant, and antimicrobial effects. Multiple studies have highlighted that the beneficial properties of Sumac extracts depend on the abundance of phytochemicals such as polyphenols, fatty acids, minerals, and fibers. Despite its wide use as a spice, the literature on Sumac effects on humans’ health and aging is still scarce. Considering its great nutraceutical potential, Sumac could be used to treat age-related diseases such as…

Formulative and stability studies of a Citrus extract to produce novel “healthy food"

Anti-inflammatory properties of an aldehydes-enriched fraction of grapefruit essential oil

2023

Chronic inflammation is linked to the development of numerous diseases and is accompanied by increased cytokine secretion. Macrophages provide a first line of defense against pathogens that under inflammatory stimuli release pro-inflammatory cytokines. The essential oil (EO) fractions obtained from Citrus spp. rich in different compounds have gained the attention of both researchers and users during the last decades. In particular, grapefruit (Citrus paradisi) peel is rich in phenolics and flavonoids with several health benefits, including anti-inflammatory actions. Additionally, its EO consists of a large number of compounds such as monoterpenes, sesquiterpenes, alcohols, aldehydes, esters…

Cultivated mushrooms: importance of a multipurpose crop, with special focus on Italian fungiculture

2020

Fungi, organisms of high nutritional value with significant bioactive compound content, are considered to be nutraceuticals, mycotherapeutics, cosmeceuticals and useful for the production of functional foods. Their cultivation allows the sustainable management of agro-industrial wastes and generates good income with low inputs, constituting a good opportunity for the development of economically depressed rural areas. There are also many possible uses for the spent substrate in various sectors. provide an overview of the nutritional value of mushrooms and the cultivation of edible and medicinal mushrooms cultivation and uses in Italy.

Drug Induced Liver Injury (DILI) due to variability in monacolin K content in Red Yeast Rice (RYR): An expert opinion

2020

Abstract Introduction Red yeast rice (RYR) is an effective cholesterol-lowering nutraceutical reversibly inhibiting 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase. As liver damage is a possible (albeit rare) side effect of HMG-CoA inhibitors, it make sense to focus on the tolerability of the liver to RYR extracts. The aim of this paper is to offer an expert opinion on the risk of liver damage by the use of RYR extract. Methods A review of the available literature has been carried out and critically reviewed by the authors. Results According to a large meta-analysis of 53 randomized clinical trials comprising 112 treatment arms, which included 8535 subjects with 4437 in the RYR arm and …

Adipose Stromal/Stem Cell-Derived Extracellular Vesicles: Potential Next-Generation Anti-Obesity Agents

2022

Over the last decade, several compounds have been identified for the treatment of obesity. However, due to the complexity of the disease, many pharmacological interventions have raised concerns about their efficacy and safety. Therefore, it is important to discover new factors involved in the induction/progression of obesity. Adipose stromal/stem cells (ASCs), which are mostly isolated from subcutaneous adipose tissue, are the primary cells contributing to the expansion of fat mass. Like other cells, ASCs release nanoparticles known as extracellular vesicles (EVs), which are being actively studied for their potential applications in a variety of diseases. Here, we focused on the importance …

Donor-π-acceptors containing the 10-(1,3-dithiol-2-ylidene)anthracene unit for dye-sensitized solar cells

2012

Two donor-acceptor molecular tweezers incorporating the 10-(1,3-dithiol-2-ylidene)anthracene unit as donor group and two cyanoacrylic units as accepting/anchoring groups are reported as metal-free sensitizers for dye-sensitized solar cells. By changing the phenyl spacer with 3,4-ethylenedioxythiophene (EDOT) units, the absorption spectrum of the sensitizer is red-shifted with a corresponding increase in the molar absorptivity. Density functional calculations confirmed the intramolecular charge-transfer nature of the lowest-energy absorption bands. The new dyes are highly distorted from planarity and are bound to the TiO(2) surface through the two anchoring groups in a unidentate binding for…

[60]Fullerene l -Amino Acids and Peptides: Synthesis under Phase-Transfer Catalysis Using a Phosphine–Borane Linker. Electrochemical Behavior

2017

International audience; A new method to link amino acid and peptide derivatives to [60]fullerene is described. It uses hydrophosphination with a secondary phosphine borane. First, the stereoselective synthesis of secondary phosphine borane amino acid derivatives was achieved by alkylation of phenylphosphine borane with gamma-iodo-alpha-amino ester reagents under phase transfer catalysis (PTC). Second, a sec-phosphine borane amino ester was saponified and coupled with alpha,gamma-diamino esters to afford the corresponding dipeptide derivatives in good yields. Finally, the hydrophosphination reaction of [60]fullerene by the sec-phosphine borane compounds was performed under PTC to obtain C-60…
