Research ArticleOpen accessIn the author namesProtection of Human Albumin against UV-C Irradiation by Natural AntioxidantsAntonio Zuorro, Roberto LavecchiaThe use of UV-C light as a means to inactivate pathogens in biological media containing blood components or plasma derivatives has recently been rediscovered. Although highly effective, these treatments may have deleterious effects on plasma proteins such as albumin, fibrinogen and immunoglobulins. Here we investigate the use of three natural antioxidants, gallic acid, nicotinic acid and ascorbic acid, as potential … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 4 · 23 Oct 2018 · 9,922 accessesView PDFCite
Research ArticleOpen accessIn the author namesAntibacterial and Anti-Quorum Sensing Activities of Selected Italian Honeys against Antibiotic-Resistant PathogensMarco Fidaleo, Roberto Lavecchia, Antonio ZuorroThree nectar honeys (eucalyptus, thyme and forest) and two honeydew honeys (fir and Metcalfa) from Italy were tested for their antibacterial activity against pathogens commonly associated with wound and burn infections, including Methicillin-Resistant Staphylococcus Aureus (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE) and Vancomycin-Resistant Enterococcus Faecalis (VREF). All honeys showed bactericidal activity against the microorganisms used, with honeydew honeys being the most … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 27 Oct 2015 · 7,050 accessesView PDFCite
Research ArticleOpen accessIn the author namesA NEW THERMAL PROCESS FOR THE RECOVERY OF METALS FROM ZINC-CARBON AND ALKALINE SPENT BATTERIESGirolamo Belardi, Roberto Lavecchia, Franco Medici et al.The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the author namesInfluence of Extraction Conditions on the Recovery of Phenolic Antioxidants from Spent Coffee GroundsAntonio Zuorro, Roberto LavecchiaThe extraction of phenolic compounds from Spent Coffee Grounds (SCG), a waste produced in large amounts worldwide, was investigated. SCG were rich in fiber and protein and had a total phenolic content of 18.75±0.43 mg GAE per gram dry weight. Extraction experiments were carried out in batch mode, using ethanol-water mixtures as solvent. A two-level factorial design was used to … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 28 May 2013 · 8,798 accessesView PDFCite
Research ArticleOpen accessIn the author namesAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,588 accessesView PDFCite
