Molecular epidemiology of type 1 and 2 dengue viruses in Brazil from 1988 to 2001

Dengue is a mosquito-borne viral infection that in recent decades has become a major international public health concern. Epidemic dengue fever reemerged in Brazil in 1981. Since 1990 more than one dengue virus serotype has been circulating in this tropical country and increasing rates of dengue hemorrhagic fever and dengue shock syndrome have been detected every year. Some evidence supports the association between the introduction of a new serotype and/or genotype in a region and the appearance of dengue hemorrhagic fever. In order to study the evolutionary relationships and possible detection of the introduction of new dengue virus genotypes in Brazil in the last years, we analyzed partial nucleotide sequences of 52 Brazilian samples of both dengue type 1 and dengue type 2 isolated from 1988 to 2001 from highly endemic regions. A 240-nucleotide-long sequence from the envelope/nonstructural protein 1 gene junction was used for phylogenetic analysis. After comparing the nucleotide sequences originally obtained in this study to those previously studied by others, and analyzing the phylogenetic trees, we conclude that, after the initial introduction of the currently circulating dengue-1 and dengue-2 genotypes in Brazil, there has been no evidence of introduction of new genotypes since 1988. The increasing number of dengue hemorrhagic fever cases seen in Brazil in the last years is probably associated with secondary infections or with the introduction of new serotypes but not with the introduction of new genotypes.

Effects of micronized sodium chloride on the sensory profile and consumer acceptance of turkey ham with reduced sodium content

The impact of sodium chloride reduction and its substitution for micronized salt on consumer acceptance of turkey ham was investigated. Five formulations - F1 (control - 2.0% NaCl), F2 (1.7% NaCl), F3 (1.4% NaCl), F4 (1.7% micronized NaCl), and F5 (1.4% micronized NaCl) - were evaluated with respect to sodium chloride content and by consumers using a nine-point hedonic scale for overall acceptability and CATA (check-all-that-apply) using 24 sensory descriptors. Trained panelists characterized the products using the flash profiling technique. Reductions in the salt content by up to 30% did not affect the overall acceptability of the samples by the consumers. However, the consumers characterized the formulations with lower salt content as "less salty and less seasoned" in comparison to the contents in the control. Products containing 1.7% NaCl were considered very similar to the control. The results obtained indicate that it is possible to reduce NaCl content by 30% without affecting consumer acceptance of the product. The use of micronized salt did not affect the sensory characteristics when compared with those of formulations containing the same level of sodium chloride indicating that micronized salt does not influence perception of salt.

Impact of socio-cultural and economic factors on vegetable consumption behaviours: case of Giresun province, Turkey

Many factors impact on food consumption behaviours. The aim of the study is to determine the impact of socio-demographic and ecological factors on vegetable consumption. A 14-question questionnaire was applied on a voluntary basis to 200 individuals who accepted to participate in the study. Their socio-demographic attributes and the vegetable consumption habits of their families were determined. Their average monthly budget for vegetables is € 31.82±12.72. The two attributes of purchased vegetables with most demand are cleanliness (61.5%) and freshness (22%). The maximum price per 1 kg of vegetables, which individuals with an income of € 301-450 can afford, is € 0.96, but for individuals with an income of > € 450, it is € 1.25. It was observed that the amount of purchased vegetables increased with the increase in the budget allocated for vegetables.

Huitlacoche yield in some maize varieties in the Mediterranean region of Turkey

Huitlacoche is the Aztecs name given to the smut galls on ears of maize caused by the pathogenic plant fungus Ustilago maydis [(DC) Corda.)]. It is known as maize mushroom, and it has been considered a delicacy and in Mesoamerica. The aim of the present study was to determine the responses of some maize varieties to the growth of the fungus in order to evaluate the prospect production of these smutty ears as a maize mushroom. A 2-year study was conducted in the Mediterranean region of Turkey in 2010 and 2011. Inoculations were performed by injecting inoculum into the ear through the silk channel of plants in plots. Each treatment had control plots. Average ear-gall (huitlacoche) severity and incidence of all the varieties were at the rates of 4.0 and 41.6%, respectively. However, the highest severity of ear-gall (6.5) and incidence (60.6%) were found in Karadeniz Yıldızı flint maize variety; colossal smutty ears were formed in the maize cultivars. This study showed that certain maize cultivars (flint corn and dent corn) can be used efficiently in the production of huitlacoche.

Survey of trace element and dietetic fiber composition of “Leblebi” which is a local snack food consumed in Turkey

Abstract In Turkey and several Middle East countries' people consume “leblebi” which is a traditional snack food made from chickpeas (Cicer arietinum L.). Chickpea products are highly nutritive and a cheap food for human consumption and have become an essential part of daily diets in the world. The present study aims to determine the chemical, nutritional and dietary composition of fifty leblebi samples marketed in Turkey. Protein values of the leblebi ranged from 19.4 to 23.9% dehulled and 20.3 to 20.8% for nondehulled leblebi while a value of 19.1% was recorded for chickpeas. Mineral results showed that Potassium (K) was the most abundant element in leblebi ranging from 6514 to 14431 mg/kg. The amount of dietary components neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL) and cellulose did not vary much between the samples analyzed.

Social Policy Reforms in Turkey : Uses of Europe

Ce mémoire analyse trois réformes majeures de politique sociale en Turquie, en deux domaines: emploi et sécurité social. En utilisant l'approche "Usage de l'Europe", ce mémoire developpe une analyse empirique et apporte une explication théorique de ces changements qui ont été introduits au cours du processus d'adhésion de la Turquie à l'Union européenne. "Les usages de l'Europe" est une approche d'européanisation qui se concentre sur le rôle des acteurs domestiques, au sein des États membres et candidats, ainsi que de leur utilisation des ressources de l'Union européenne. Les études de cas utilisées dans cette thèse démontrent l'introduction de changements au niveau de l'État-providence; ainsi, l'approche originelle est suppléée par des concepts provenant de la littérature sur la politique partisane, les institutions formelles et l'héritage des politiques. Cette recherche utilise la méthode de l'analyse de processus pour suivre la réforme des règlements du travail par la voie de reconstitution des droits individuels des travailleurs et de l'Agence d'emploi en Turquie jusqu'en 2003, ainsi que la transformation du système de sécurité sociale en 2008. Ces trois réformes représentent des changements majeurs tant sur le plan institutionnel que politique en Turquie depuis 2001. Afin de comprendre "les usages de l'Europe" dans ces réformes politiques, l'analyse empirique questionne, si, quand et comment les acteurs turcs ont utilisé les ressources, les références et les développements politiques de l'Union européenne lors de ce processus dynamique de réforme. Les réformes du système de sécurité sociale, des règlements du travail, en plus de la reconstitution de l'Agence d'emploi étaient à l'ordre du jour en Turquie depuis les années 1990. La réforme des règlements du travail ont entraîné l'introduction des accommodements flexibles au travail et une révision de la Loi du travail permettant l'établissement d'une législation de la sécurité d'emploi. La reconstitution de l'Agence d'emploi visait à remplacer la vieille institution défunte par une institution moderne afin d'introduire des politiques d'activation. La réforme de sécurité sociale comprend les pensions de retraite, le système de santé ainsi que l'administration des institutions de sécurité sociale. Les principaux résultats révèlent que la provision des ressources de l'Union européenne en Turquie a augmenté à partir de la reconnaissance de sa candidature en 1999 et ce, jusqu'au lancement des négociations pour son adhésion en 2005; ce qui fut une occasion favorable pour les acteurs domestiques impliqués dans les processus de réformes. Cependant, à l'encontre de certaines attentes originelles de l'approche de "les usages de l'Europe", les résultats de cette recherche démontrent que le temps et le sort de "les usages de l'Europe" dépendent des intérêts des acteurs domestiques, ainsi de leurs stratégies tout au long de ce processus de réforme, plutôt que des phases du processus ou la quantité des ressources fournies par l'Union européenne.

Mosquito larvae borne viruses from the central travancore region of kerala: isolation and characterization

The present study was initiated when several massive outbreaks of Chikungunya, Dengue and Japanese Encephalitis were frequently reported across the State of Kerala. Multiple symptoms persisted among the affected individuals and the public health officials were in search of aetiological agents responsible for the out breaks and, other than clinical samples no resources were available. In this context, a study was undertaken to focus on mosquito larvae to investigate the viruses borne by them which remain silently prevalent in the environment. The study was not a group specific investigation limited to either arbovirus or enterovirus, but had a broad spectrum approach. The study encompassed the viral pathogens that could be isolated, their impact when passaged through cell lines, growth kinetics, titer of the working stocks in specific cell line, the structure by means of transmission electron microscopy(TEM), the one step growth and molecular characterization using molecular tools.

Challenges of the accession of Turkey into the European Union

Turkey's accession to the European Union (EU) has become, over the years, one of the most contentious issues of European integration. On October 3rd 2005, the European Commission began negotiations for its accession, and, although they will probably not be completed within a decade, its objective is the full accession to the Union. Turkey's accession to the EU presents challenges for both parties, but especially for the European Union. There are very different challenges from the previous accessions, indeed. This work aims to analyze the challenges the EU will face towards Turkey's possible accession to the European Community. Therefore, this work has been divided into three sections. In the first of them, entitled "Brief history of a complex negotiation", the negotiation is briefly described. The second, "Aspects to take into account for Turkey's accession to the European Union", in which different relevant (geopolitical, economic and financial, demographic, cultural and religious) aspects of the possible a cession are discussed: aspects that will have an important impact in the development and performance of the European Community, once accession is fulfilled. The third and last section, "Turkey's incorporating challenges", discusses the challenges the EU will have to face with the potential accession of Turkey, specifically concerning four dimensions: institutional capacity, regional and cohesion policy, EU common security and foreign policy.

The use of insect cells to identify potent and selective inhibitors of the replication of the Dengue and Chikungunya viruses and unravel their molecular mechanism of action

Dengue and Chikungunya viruses cause the most important arthropod-borne viral infections for humans. These viruses are predominant in tropical and subtropical regions. In addition, these viruses are predominant in tropical and subtropical regions. Dengue mortality rate is around 1.2 to 3.5% and deaths due to chikungunya fever are around 1 in 1000; however, half of chikungunya-infected patients evolve into a chronic state that can persist for months up to years. There are no antiviral drugs available for DENV and CHIKV treatment and prevention. Moreover, vector control strategies have failed so far. Thus, the development of potent inhibitors for a broad spectrum of RNA viruses is urgently needed. We established and characterized a new embryonic insect cell line from Culex quinquefasciatus mosquito. Also we established the flaviviruses and alphavirus replication, both in C6/36 and Lulo insect cell lines, as well as in Vero cell line. In addition we carried out a reference compound library and reference panel of assays and data for DENV, which provides a benchmark for further studies. During this study, a panel of 9 antiviral molecules, with proven in vitro anti-dengue virus activity and that act at different stages of the DENV life cycle, was selected. Finally, Favipiravir or T-705, was identified as inhibitor in vitro and in vivo of alphaviruses and the mutation K291R in nsP4, which is responsible of the polymerase activity, was found as the mode of action in CHIKV. Interestingly, lysine in motif F1 is also highly conserved in positive-stranded RNA viruses and this might explain the broad spectrum of T-705 antiviral activity.

Who remembers Turkey's pre-accession? CEPS Special Report No. 74/December 2012

In 2005 the EU and Turkey officially started accession negotiations that were intended to lead to Turkey’s full membership of the EU. Yet today, the Turkish accession process has virtually ground to a halt and lost all credibility. Talk of alternatives to full membership can be heard from various sides; we highlight four instances of what we call ‘parallelism’, namely the elusive concept of a ‘privileged partnership’, the EU-Turkey customs union, the recently launched ‘Positive Agenda’ and Turkish participation in the Energy Community Treaty. While a privileged partnership represents a more comprehensive but still remote framework for EU-Turkish relations, the latter three are merely an escape route from preaccession. We conclude our analysis with a discussion on Turkey’s possible membership of the European Economic Area, which in effect would serve none of the parties involved. We conclude that both partners, the EU and Turkey, would be well advised to remember their pre-accession commitments of 13 years ago – for their mutual benefit.
