Coffee and endothelial function: a battle between caffeine and antioxidants ?

2010

Although coffee is largely consumed by adults in Western countries, controversy exists about its impact on the cardiovascular system. We recently demonstrated that caffeinated and decaffeinated espresso coffee have different acute effects on endothelial function in healthy subjects, measured using flow-mediated dilation (FMD) of the brachial artery. In this study, we measured the anti-oxidant capacity of two coffee substances in terms of free stable radical 2,2-diphenyl-1-picryl-hydrazyl 50% inhibition (I(50) DPPH). The caffeinated coffee had a slightly higher anti-oxidant capacity than decaffeinated espresso coffee (I(50) DPPH: 1.13±0.02 vs 1.30±0.03 μl; P0.001). We suggest that the unfavo…

Bioactive components of caper (Capperis spinosa L.) from Sicily and antioxidant effects in a red meat simulated gastric digestion

2007

An increasing body of evidence on the association between adherence to the Mediterranean diet and healthy status is being accumulated. Floral buds of Capparis spinosa L. are commonly used in the Mediterranean cuisine as flavoring for meat and other foods. The present study evaluated bioactive components and antioxidant activity of Sicilian capers stabilized in salt. Whereas alpha-tocopherol was absent, low levels of gamma-tocopherol and vitamin C were measured. With reference to one serving size (8.6 g of capers), rutin was 13.76 mg, isothiocyanates, recently acknowledged as anticarcinogen phytochemicals, were 42.14 micromol, total phenols were 4.19 mg of gallic acid equivalents (GAE), and …

In vitro bioaccessibility, transepithelial transport and antioxidant activity of Urtica dioica L. phenolic compounds in nettle based food products

2016

Nettle (Urtica dioica L.) is a well-known plant with a wide historical background use of stems, roots and leaves. Nettle leaves are an excellent source of phenolic compounds, principally 3-caffeoylquinic acid (3-CQA), caffeoylmalic acid (CMA) and rutin. The aim of this work was to evaluate the bioaccessibility (BAC), the bioavailability (BAV) and the antioxidant activity of nettle phenolic compounds present in foods and supplements. The BAC of nettle phenolics was evaluated with an in vitro dynamic digestion of real food matrices: the type of food matrix and chemical characteristic affected the kinetics of release and solubilization, with the highest BAC after duodenal digestion. A study of…

In vitro digestion of betalainic foods. Stability and bioaccessibility of betaxanthins and betacyanins and antioxidative potential of food digesta.

2008

Betalains are considered to be bioactive dietary phytochemicals. The stability of betacyanins and betaxanthins from either fresh foods or manufactured products of cactus pear fruit ( Opuntia ficus indica L. Mill. cv. Gialla and Rossa) and red beet ( Beta vulgaris L. ssp. vulgaris) was assessed in a simulated oral, gastric, and small intestinal digestion and compared with the digestive stability of purified pigments. A minor loss of indicaxanthin, at the gastric-like environment only, and a decrease of vulgaxanthin I through all digestion steps were observed, which was not affected by food matrix. In contrast, food matrix prevented decay of betanin and isobetanin at the gastric-like environm…

Responsabilité Sociale de l'Entreprise et pratiques de Gestion des Ressources Humaines

2006

As far as human resource management practices (HRM) are concerned, how do French companies respond to corporate social responsibility (CSR)? Are they eager to develop practices beyond the existing legal rules? To answer these questions, we present the results of an inquiry involving 106 HR managers who mainly belong to large manufacturing companies. Their statements, collected by questionnaire, are focused on a few "responsible" HRM practices: - Recruiting practices in favour of disabled or non skilled persons - Training practices promoting the access or the return to work - Communication practices encouraging the dialog between the managers and the employees. According to our results, the …

Time-course changes of plasma lipid levels and lipoprotein pattern after feeding in cultured sea bass, Dicentrarchus labrax L.

1988

Results of a study of plasma lipids levels and lipoprotein pattern modification during digestion in sea bass indicate that, after feeding, non-esterified fatty acids are rapidly delivered in plasma, while triglycerides reach a maximum concentration only 24 h later. The time-course change of the lipoprotein pattern shows a relationship between their concentration and the lipid class carried.

EUA and sCER Phase II Price Drivers: Unveiling the reasons for the existence of the EUA-sCER spread

2011

International audience; This article studies the price relationships between EU emissions allowances (EUAs) - valid under the EU Emissions Trading Scheme (EU ETS) - and secondary Certified Emissions Reductions (sCERs)--established from primary CERs generated through the Kyoto Protocol's Clean Development Mechanism (CDM). Given the price differences between EUAs and sCERs, financial and industrial operators may benefit from arbitrage strategies by buying sCERs and selling EUAs (i.e. selling the EUA-sCER spread) to cover their compliance position as industrial operators are allowed to use sCERs towards compliance with their emissions cap within the European system up to 13.4%. Our central res…

Arborescent Supply Chains: the effect of OUT policies

2013

The objective of this paper is to analyze the impact of the smoothing replenishment rules on a divergent supply chain. To this purpose we simulate a classical four echelon serially- linked supply chain model and an arborescent supply chain model under two scenarios, i.e. classical OUT and smoothing replenishment rule. We show that the divergent supply chain structure always performs worse than the serial supply chain and how smoothing the order pattern may decrease this discrepancy.

A partire dalla manutenzione: strategie per i siti archeologici

2010

A dieci anni dal Regolamento attuativo della Legge Merloni, il contributo punta ad aggiornare lo stato dell’arte sulla manutenzione dei siti archeologici. Nonostante i numerosi passi avanti, il quadro mostra ancora alcune ambiguità, mentre molti siti continuano a versare in condizioni precarie. La limitatezza delle risorse disponibili, tanto più grave pensando alla vastità del patrimonio culturale, per molto tempo ha costituito un alibi per trascurare la manutenzione. Invece essa costituisce un incentivo per una più efficiente gestione. Si tratta: dell’ambiguità del rapporto manutenzione/conservazione, dei paradossi normativi e dei limiti della programmazione, della specificità della manute…
