No full textAntonis Samaras: The Permanent Campaign Strategy of a Centre-Right Prime Minister
No full textThis chapter focuses on the analysis of Antonis Samaras’ political background and campaigning style of governing in the era of sovereign debt crisis and the implementation of the memoranda. It measures and assesses permanent campaigning of Samaras against the three categories of the proposed theoretical framework (capacity building and strategy, paid and owned media as well as earned media). It finds that as prime minister and in line with his predecessors did follow the permanent campaign trend though he did not use all its features. He put more emphasis on factors related to capacity building and strategy as well as earned media rather than most of the components of the paid and owned media that focused on the use of social media, except for the election themes and negative campaigning. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG
Very-Long-Chain Resorcinolic Lipids of Ailanthus altissima Samaras
No full textTwo new very-long-chain 5-n-alkylresorcinol (AR) homologues, that is, 5-n-nonacosylbenzene-1,3-diol and 5-n-hentriacontylbenzene-1,3-diol, were isolated from acetone extracts of Ailanthus altissima samaras. These phenolic compounds were detected in nearly equal proportions, although their total content varied considerably between samples from urban-grown trees. No correlation was observed between AR levels and the physiological state of the tree, suggesting that environmental conditions may strongly influence AR biosynthesis in A. altissima. Furthermore, the isolated AR mixture exhibited antifungal activity against soil-borne phytopathogens of the genera Fusarium and Rhizoctonia

Off-label use of hormones as an antiaging strategy: a review
No full textNikolaos Samaras,1 Maria-Aikaterini Papadopoulou,2 Dimitrios Samaras,3 Filippo Ongaro1 1Clinique Générale Beaulieu, Geneva, Switzerland; 2Department of Internal Medicine, Rehabilitation and Geriatrics, Geneva University Hospitals, Geneva, Switzerland; 3Department of Medical Specialties, Clinical Nutrition, Geneva University Hospitals, Geneva, Switzerland Abstract: Given demographic evolution of the population in modern societies, one of the most important health care needs is successful aging with less frailty and dependency. During the last 20 years, a multitude of anti-aging practices have appeared worldwide, aiming at retarding or even stopping and reversing the effects of aging on the human body. One of the cornerstones of anti-aging is hormone replacement. At present, women live one third of their lives in a state of sex-hormone deficiency. Men are also subject to age-related testosterone decline, but andropause remains frequently under-diagnosed and under-treated. Due to the decline of hormone production from gonads in both sexes, the importance of dehydroepiandrosterone (DHEA) in steroid hormone production increases with age. However, DHEA levels also decrease with age. Also, growth hormone age-associated decrease may be so important that insulin growth factor-1 levels found in elderly individuals are sometimes as low as those encountered in adult patients with established deficiency. Skin aging as well as decreases in lean body mass, bone mineral density, sexual desire and erectile function, intellectual activity and mood have all been related to this decrease of hormone production with age. Great disparities exist between recommendations from scientific societies and actual use of hormone supplements in aging and elderly patients. In this article, we review actual data on the effects of age related hormone decline on the aging process and age-related diseases such as sarcopenia and falls, osteoporosis, cognitive decline, mood disorders, cardiovascular health and sexual activity. We also provide information on the efficiency and safety of hormone replacement protocols in aging patients. Finally, we argue on future perspectives of such protocols as part of everyday practice.

Design and characterization of magnetic scaffolds for bone tumor hyperthermia
No full textMagnetic tissue scaffolds are a promising powerful tool for performing interstitial tumor hyperthermia against the residual bone cancer cells, after surgical intervention. The design of the implant architecture is crucial for several biomedical requirements. However, to date, the influence of implant topology on the hyperthermia treatment outcome has never been assessed. Furthermore, the heating ability is a function of sample mass and geometry. In this work, a simple methodology for designing biomimetic scaffolds using triply periodic minimal surfaces is presented. A set of geometries is 3D printed by fused deposition modeling, using a commercial poly-lactic acid filament filled with magnetite particles, never tested for biomedical applications. Magnetic scaffolds were thoroughly characterized by performing static magnetic measurements, differential scanning calorimetric and thermogravimetric analysis, but, mostly, by carrying out calorimetric measurements to determine their hyperthermic potential under different experimental conditions. Numerical multiphysics simulations with a commercial finite element software were performed, resulting in good agreement with the measurements. The scaffolds were exposed to a magnetic field with 15 mT strength, working at 400 kHz, in air, and the surface temperature was recorder using infrared camera. The manufactured magnetic scaffolds can increase the temperature above 41°C (about 54-57°C), in 40-60 s. In distilled water, for a 30 mT magnetic field and 400 kHz, the temperature was recorded using an optic fiber and we observed that all the sample could be used as thermo-seed for cancer therapy. Finally, the scaffolds were tested in agarose phantoms and their hyperthermic potential was quantified
The use of IT to increase nutritional awareness in young children
No full textIt has been well documented that obesity amongst young children is on the increase. By the age of 5 the levels of obesity is alarming and is much greater than expected in comparison to the national standards. To address this problem an overall health programme is required encompassing healthy eating and physical activity. However, a radical change of this nature has not shown any long-term benefits and can result in a negative attitude from the child. Therefore, more subtle ways of increasing awareness in children about healthy eating were thought to be the key. Since children are spending an increasing amount of their free time playing computer games it was thought that this would be a good way of introducing them to healthy eating. Therefore, a prototype system is developed and tested to identify whether IT can be used to raise nutritional awareness in young children. The results show that the increase is marginal but the system did encourage discussion about the effects of food amongst a group of children aged between 4-5
Le lit d’Héra dans l’Héraion d’Argos
No full textDas Belt der Hera im Héraion von Argos
Im argivischen Heraion, im Pronaos des Tempels, hat Pausanias (II, 17, 3) ein „Bett der Hera“ gesehen, das die Religionsforscher in Zusammenhang mit gewissen Riten zu Ehren der Hochzeitsgöttin gebracht haben. Andere Betten, von verschiedener Größe und aus verschiedenen Materien, waren in Tempeln ausgestellt oder befanden sich ais Beigaben in Gräbern. Noch andere, wie ein Exemplar des Louvre, sind unbekannter Herkunft. Seit mykenischer Zeit sind durch literarische oder archäologische Zeugnisse Mythen und Feste der Hierogamie überall in der griechischen Welt belegt. Die Vasenmalerei dokumentiert die Vorbereitung des Hochzeitsbettes, eine Sitte die in manchen Gegenden Griechenlands heute noch fortgeführt wird.Pausanias, II, 17, 3, signale dans le pronaos du temple de l'Héraion d’Argos un «lit d’Héra», que les commentateurs ont rattaché à divers rites en l’honneur de la déesse du mariage. D’autres lits, avec des variantes de taille et de matériau, étaient exposés dans des temples ou faisaient partie de mobiliers funéraires. Pour d’autres encore, comme un lit conservé au Musée du Louvre, le contexte exact de la trouvaille est inconnu. Depuis l’époque mycénienne, des mythes et des fêtes de hiérogamie sont attestés, littérairement ou archéologiquement, partout dans le monde grec. La peinture de vases montre la préparation du lit nuptial, coutume qui connaît encore des prolongements dans certaines régions de la Grèce moderne.Kauffmann-Samaras Aliki.

A New Framework for the Citation Indexing Paradigm
No full textA new citation indexing paradigm is proposed: the cascading citation indexing framework (c2IF, for short). It improves the way research publications are assessed for their impact in promoting science and technology. Given a collection of articles and their citation graph, citations are considered at the (article, author) level. Each one article is uniquely identified by means of the Digital Object Identifier (DOI, http://www.doi.org). To identify each one author uniquely, a Universal Author Identifier (UAI) scheme is established. In addition to the citations directly made to a given (article, author) pair, citation paths that target each one citing article are also considered. The granularity of the paradigm is further increased by introducing the concept of the chord, whereby a citation path of length one co-exists with paths of length two or higher, involving the same source- and target- articles. The c2IF output emerges in the form
of a medal standings table, analogous to the one that ranks teams at athletic events: when two (article, author) pairs receive the same number of (direct) citations, the one that is cited by more popular articles (i.e. articles that comprise targets to a larger number of paths in the citation graph), is assigned a higher rank value
