Wine Consumption and Oral Cavity Cancer: Friend or Foe, Two Faces of Janus

The health benefits of moderate wine consumption have been extensively studied during the last few decades. Some studies have demonstrated protective associations between moderate drinking and several diseases including oral cavity cancer (OCC). However, due to the various adverse effects related to ethanol content, the recommendation of moderate wine consumption has been controversial. The polyphenolic components of wine contribute to its beneficial effects with different biological pathways, including antioxidant, lipid regulating and anti-inflammatory effects. On the other hand, in the oral cavity, ethanol is oxidized to form acetaldehyde, a metabolite with genotoxic properties. This review is a critical compilation of both the beneficial and the detrimental effects of wine consumption on OCC.

THEALANS: IN ADDITION TO THE ABOVE (ON A. ALEMANY'S BOOK "SOURCES ON THE ALANS: A CRITICAL COMPILATION")

Фундаментальный труд А. Алеманя Аланы в древних и средневе ковых письменных источниках , вышедший в свет в 2003 г., открывает новые возможности для развития алановедческих исследований. А. Алемань создал структуру, позволяющую дополнять его работу источниками, которые по тем или иным причинам не вошли в его книгу. В настоящей статье приводится ряд источников, которые значительно дополняют структуру, предложенную А. Але манем: Иоанн Галонифонтибус, Никифор Григора, Ф. Брун, Венецианская хроника Мартина Канале и т. д. Автор предлагает специалистамисторикам подклю читься к работе по дополнению структуры, созданной А. Алеманем, чтобы со временем научному сообществу была представлена более полная картина, от ражающая весь спектр источников по средневековым аланам. The book Sources on the Alans: a critical compilation by a wellknown Catalonian scholar AugustiAlemany was published in 2003 and has become a signi cant phenomenon in the eld of historical Alanian studies. A. Alemanis fundamental work opens new opportunities to develop research in the eld of Alanian studies. The author compiled numerous written evidences on the Alans, that had come to us from the past centuries. Among other issues A. Alemani created a structure which enables to complement his work with sources on the Alans that, for whatever reason, were not included in the book. The author of the article provides a number of sources that complement signi cantly the structure which was suggested by A. Alemany. These sources are Johannes de Galonifontibus, NicephorusGregoras, F. Bruun, the Venetian chronicle of Martin da Canale and etc. The article calls upon historians that specialize in this particular eld to join the effort to complement the structure created by A. Alemany with sources that were not included in his book. This is to be done in order to provide eventually researches with the opportunity to present the scienti c community a full picture containing the whole spectrum of sources on the medieval Alans.

Revision and update of the checklist of copepods (Crustacea: Hexanauplia) of the Colombian Caribbean

The aim of the study was to obtain a revised and updated checklist of the species of copepods of the Colombian Caribbean. Methods for updating included a critical compilation of records in published and unpublished articles, and our own results of a study of zooplankton in a project on bioinvasions of coastal waters, conducted in 2010. Twenty taxa reported solely in undergraduate thesisneed taxonomical comprobation and were excluded from the inventory. As a baseline, we used the most recent inventory published by Medellín-Mora and Navas (2010). Ten species recorded in the already mentioned project are new records. Thirteen species reported by other researchers in publications after 2010 increased the species list. The inventory totals 214 species of copepods (158 Calanoida, 38Cyclopoida, 15 Harpacticoida, 2 Mormonilloida and 1 Monstrilloida). Most species are planktonic (201), while only a few are benthic (10) or epibenthic (3). Nomenclature of the taxa was revised and updated as well. The highest copepod diversity corresponds to the ecoregion Colombian Oceanic (127 species), followed by Tayrona (94), Magdalena (82) and Morrosquillo (78). The lowest number corresponds to San Andrés and Providencia Archipelago (49). The limited information existing about benthic and parasitic copepods warrants an increment on the study these groups. Most of them belong to orders Harpacticoida and Siphonostomatoida.

Statistical Design, a Powerful Tool for Optimizing Biosurfactant Production: A Review

Biosurfactants (Bs) have been studied for decades and applied in different industrial sectors because of their competitive biochemical characteristics, and the fact that they are environmentally friendly. Current scientific investigations mainly involve the search for novel Bs producing organisms with attractive characteristics. Bs are expected to replace synthetic surfactants in the near future, but low production yields and inefficient downstream processes have prevented their widespread use. Although there are numerous reports on Bs optimization, to date there has been no critical compilation or revision of the statistical designs and strategies employed for improved production. The purpose of this mini review is to briefly discuss the factors that affect Bs production and the importance of statistical design as an essential tool for increasing production.
