The effect of essential oils on norovirus surrogates

2013

Abstract Essential oils (EOs) have long been applied as flavoring agents in foods, and due to their content in antimicrobial compounds, they have potential as natural agents for food preservation. In this study the effect of three EOs, clove, oregano and zataria, was evaluated on the infectivity of norovirus surrogates, i.e. feline calicivirus (FCV) and murine norovirus (MNV). Different concentrations of EOs were individually mixed with each virus at titers of ca. 7–8 log TCID 50 /ml and incubated for 2 h at 4 °C and 37 °C. The infectivity of the recovered viruses after triplicate treatments was evaluated by cell-culture assays. 2% of oregano EO at 37 °C decreased the FCV titers by 3.75 log…

Straightforward One-Pot Synthesis of New 4-Phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one Derivatives: X-ray Single Crystal Structure and Hirshfeld Ana…

2022

A straightforward one-pot route for the synthesis of a new 4-phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one is reported form the direct hydrazinolysis of triketo ester and hydrazine hydrate in ethanol. 4-Phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one was subjected to aza-Michael addition and N-alkylation on reaction with a set of alkylating agents in the presence of K2CO3. Hydrazinolysis of 4-phenyl-1,2,5,6-tetraazafluoranthen-3(2H)-one ester to hydrazide and conversion of hydrazide to thiosemicarbazide were successful. X-Ray single crystals analysis and 1H, 13C NMR were used for unambiguous structure confirmation. The O…H, N…H, C…N and C…C in 2, and the N…H, …

Synthesis, X-ray Structure of Two Hexa-Coordinated Ni(II) Complexes with s-Triazine Hydrazine Schiff Base Ligand

2023

The hydrazine s-triazine ligand (E)-4,4’-(6-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)-1,3,5-triazine-2,4-diyl)dimorpholine (DMPT) was used to synthesize two new Ni(II) complexes via a self-assembly technique. The two complexes were synthesized by a one-pot synthesis strategy and characterized by elemental analysis, FTIR and single-crystal X-ray diffraction analysis to be [Ni(DMPT)(H2O)3](NO3)2.3H2O (1) and [Ni(DMPT)(H2O)3](NO3)2.H2O (2). The structures of both complexes were very similar regarding the coordination sphere and counter anions, but differ only in the number of the crystal water molecules. In the case of complex 1, there are three water molecules instead of one H2O molecu…

Synthesis and Characterizations of Novel Isatin-s-Triazine Hydrazone Derivatives : X-ray Structure, Hirshfeld Analysis and DFT Calculations

2023

A novel series of isatin-s-triazine hydrazone derivatives has been synthesized and reported herein. The synthetic methodology involved the reaction of s-triazine hydrazine precursors with isatin derivatives in the presence of CH3COOH as a catalyst and EtOH as solvent to afford the corresponding target products 6a-e in high yields and purities. The characterization data obtained from elemental analysis, FT-IR, NMR (1H- and 13C-) were in full agreement with the expected structures. Furthermore, an X-ray single crystal diffraction study of one of the target s-triazine hydrazone derivatives, 6c confirmed the structure of the desired compounds. It crystallized in the triclinic crystal system and…

Professional development for teachers: a world of change

2009

As the industrialised world shifted to an interdependent and global society, formal schooling was quickly recognised as a major factor in achieving a knowledge society of lifelong learners capable of transforming and revitalising organisations. Teachers were encouraged to engage in learning together to improve teaching and, by extension, improve learning for the children in their care. This article identifies three emerging trends intended to broaden teachers' learning and enhance their practices through continuous professional development: glocalisation, mentoring, and re‐thinking teacher evaluation. The body of the article indicates how these three trends are unfolding in Australia, Engla…

Lifelong Learning: international injunctions and university practices

2001

JEAN-PIERRE JALLADE & JOSE´-GINE´S MORAIntroductionThe aim of this article is to elucidate whether the international discourse onlifelong learning (LLL) had any influence on what universities are doing in thisfield. International trends will be examined on the basis of OECD, UNESCO,EU and Council of Europe policy documents. University practice will be based onan enquiry carried out in 28 universities in seven European countries in 1999–2000 in the framework of the project Lifelong Learning and the University,sponsored by the EU/DG 12.Between the international policy discourse and university practice stands thenational layer of policy-making, giving rise to two interesting issues: first, don…
