References about its use from 59 local populations for the treatment of gastrointestinal disorders or as a cosmetic agent can even 60 be encountered in ancient texts of Galen, Theophrastus and Dioscorides. Nowadays, this 61 versatile resin has been rediscovered, not only as a traditional remedy and aromatic agent, but as 62 a potent phytotherapeutic product with various biological properties. 63 Aim of the study: The aim of this study is to quote the summation of the ethnopharmacology, 64 phytochemical profile and pharmacological properties of the resin of Pistacia lentiscus var. Chia 65 and thus provide the scientific community with a summary of the research conducted so far. 66 Furthermore, perspectives and uses are being discussed and studied so as to broaden the field of 67 its applications. 68 Materials and Methods: A comprehensive review of the literature on Pistacia lentiscus var. Chia 69 was performed using as resources scientific databases such as Scopus, Sciencedirect, Pubmed 70 and Web of science, studies and traditional books provided by the Chios Mastiha Growers 71 Association as well as PhD and Master’ s theses. 72 Results: Chios mastic gum has been used as a traditional medicine over the last 2500 years. More 73 than 120 chemical compounds have been identified in the resin and the major components are a 74 natural polymer, acidic and neutral triterpenes and volatile secondary metabolites. Several plant 75 extracts and compounds have been studied for their antibacterial, anti-inflammatory, antioxidant, 76 anti-ulcer, anti-diabetic, cardioprotective and anti-cancer properties in vitro and in vivo . Clinical 77 interventions and trials have also showed the therapeutic potential of Chios mastic gum. In 2015 4 78 Pistacia lentiscus L., resin (mastic) was recognized as a herbal medicinal product with traditional 79 use by the European Medicines Agency (EMA) with two therapeutic indications (mild dyspeptic 80 disorders & skin inflammation/ healing of minor wounds). Over the last years, Chios mastic gum 81 is widely involved in medicinal products, food supplements and cosmetics and has become 82 object of study, also in the field of Pharmacotechnology. 83 Conclusions: Chios mastic’s beneficial properties have been demonstrated in the treatment of 84 gastrointestinal disorders, wound healing, skin inflammations, plasma lipid and blood sugar 85 reduction and oral care. These properties are attributed to triterpenes

  • Code of Conduct
    CODE OF CONDUCT Chios Eastern Shore Response Team (Offene Arme e.V.) GENERAL INFORMATION Since the formation of the very first team, hundreds of volunteers have contributed their time, energy and resourcefulness to provide direct humanitarian aid that meets immediate needs for refugees and asylum seekers arriving after long journeys from war-torn countries or countries where oppression has been untenable and equally life threatening. Refugees arrive in the European Union on the Chios’ Eastern Shore or at Chios Port after a short but no less fear-filled, life threatening crossing of the Aegean Sea from Turkey. On arrival, they are met by a warm CESRT welcome, albeit in very challenging conditions: our team provides water, food, immediate basic care, warm blankets and clothes with warm smiles engaging in friendly exchanges discretely listening to and with an observant eye to identify the most vulnerable individuals for the immediate first care by accompanying doctors, one of our own and others from Salvemento Maritimo Humanitario (SMH). It is the warmth of welcome and the direct and immediate aid that is the very foundation of CESRT’s work. Over time CESRT work has evolved and diversified to include various post-arrival social and support services responding to needs created by the extended ‘detention’ of refugees pending the resolution of their applications – The Warehouse continues to be central to the preparation and provision of food, water, clothes, hygiene and other essentials to new arrivals and on an on-going basis to all refugees detained on Chios through regular distributions to those accommodated in apartments and directly to Vial Camp.

  • Response to the Wildfires Affecting the Island of Chios, Greece, in 2012
    International Forest Fire News (IFFN) No. 42 (January–December 2012), p. 94–106 ISSN 1029-0864 (web) Response to the Wildfires affecting the Island of Chios, Greece, in 2012 Between 18 and 22 August 2012 the Greek island Chios was affected by a severe wildfire. More than 12,700 hectares of forests, pastures and other vegetation types were burned. While fires are not an unusual phenomenon on Chios (Fig. 1) the wildfire of 2012 was very severe with regards to the ecological and socio-economic consequences. The fires were burning at extremely dry and windy conditions and were difficult to control (Fig. 2 and 3) and sent a smoke plume across, the Aegean Sea towards Crete Island, which was visible from space (Fig. 4). Figure 1. Reconstruction of wildfire occurrence on Chios Island between 1984 and 2009. Source: Ioannis Mitsopoulos, Global Fire Monitoring Center (GFMC) Figures 2 and 3. The fast spread and the large size of the wildfires on Chios exceeded the capacities of local fire service to bring the fires swiftly under control. Source: Municipality of Chios. Source: Local media. Figure 4. On 18 August 2012 the MODIS sensor on NASA’s satellite Aqua the smoke plume stretching from Chios Island to the Southwest and reaching Crete Island. Source: NASA. Most importantly, however, were the devastating impacts of the wildfire on the island's trademark mastic gum industry, which is based on the world's only mastic tree plantations. About a quarter of the island's mastic groves have been wiped out. In cash terms, producers were facing losing up to three million Euros a year, because after replanting, it takes up to a decade before producers can start tapping the trees for their aromatic gum.

  • The Genoese in Chios, I346-1566
    418 July Downloaded from The Genoese in Chios, i346-1566 F the Latin states which existed in Greek lands between the Latin conquest of Constantinople in 1204 and the fall of O http://ehr.oxfordjournals.org/ the Venetian republic in 1797, there were four principal forms. Those states were either independent kingdoms, such as Cyprus ; feudal principalities, of which that of Achaia is the best example ; military outposts, like Rhodes ; or colonies directly governed by the mother-country, of which Crete was the most conspicuous. But the Genoese administration of Chios differed from all the other Latin creations in the Levant. It was what we should call in modern parlance a Chartered Company, which on a smaller at Memorial University of Newfoundland on April 4, 2015 scale anticipated the career of the East India and the British South Africa Companies in our own history. The origins of the Latin colonization of Greece are usually to be found in places and circumstances where we should least expect to find them. The incident which led to this Genoese occupation of the most fertile island of the Aegean is to be sought in the history of the smallest of European principalities—that of Monaco, which in the first half of the fourteenth century already belonged to the noble Genoese family of Grimaldi, which still reigns over it. At that time the rock of Monaco and the picturesque village of Roquebrune (between Monte Carlo and Mentone) sheltered a number of Genoese nobles, fugitives from their native city, where one of those revolutions common in the medieval republics of Italy had placed the popular party in power.

Received: 9 December 2009; in revised form: 4 February 2010 / Accepted: 16 February 2010 / Published: 17 February 2010 Abstract: The explosive increase in world population, along with the fast socio-economic development, have led to an increased water demand, making water shortage one of the greatest problems of modern society. Countries such as Greece, Saudi Arabia and Tunisia face serious water shortage issues and have resorted to solutions such as transporting water by ships from the mainland to islands, a practice that is expensive, energy-intensive and unsustainable. Desalination of sea-water is suitable for supplying arid regions with potable water, but extensive brine discharge may affect marine biota. To avoid this impact, we explore the option of directing the desalination effluent to a solar saltworks for brine concentration and salt production, in order to achieve a zero discharge desalination plant. In this context, we conducted a survey in order to evaluate the potential of transferring desalination brine to solar saltworks, so that its disposal to the sea is avoided.
