Low-Grade Systemic Inflammation Interferes with Anabolic and Catabolic Characteristics of the Aged Human Skeletal Muscle.
No full textAging is associated with the development of chronic low-grade systemic inflammation (LGSI) characterized by increased circulating levels of proinflammatory cytokines and acute phase proteins such as C-reactive protein (CRP). Collective evidence suggests that elevated levels of inflammatory mediators such as CRP, interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α) are correlated with deteriorated skeletal muscle mass and function, though the molecular footprint of this observation in the aged human skeletal muscle remains obscure. Based on animal models showing impaired protein synthesis and enhanced degradation in response to LGSI, we compared here the response of proteolysis- and protein synthesis-related signaling proteins as well as the satellite cell and amino acid transporter protein content between healthy older adults with increased versus physiological blood hs-CRP levels in the fasted (basal) state and after an anabolic stimulus comprised of acute resistance exercise (RE) and protein feeding. Our main findings indicate that older adults with increased hs-CRP levels demonstrate (i) increased proteasome activity, accompanied by increased protein carbonylation and IKKα/β phosphorylation; (ii) reduced Pax7+ satellite cells; (iii) increased insulin resistance, at the basal state; and (iv) impaired S6 ribosomal protein phosphorylation accompanied by hyperinsulinemia following an acute RE bout combined with protein ingestion. Collectively, these data provide support to the concept that age-related chronic LGSI may upregulate proteasome activity via induction of the NF-κB signaling and protein oxidation and impair the insulin-dependent anabolic potential of human skeletal muscle
The Past in the Present: A Living Heritage Approach - Meteora, Greece
No full textThe Past in the Present deals with the complexities in the operation and management of living heritage sites. It presents a new interpretation of such sites based on the concept of continuity, and its evolution to the present. It is demonstrated that the current theoretical framework and practice of conservation, as best epitomised in a values-based approach and the World Heritage concept, is based on discontinuity created between the monuments (considered to belong to the past) and the people of the present, thus seemingly unable to embrace living heritage sites. From this position, the study suggests an innovative approach that views communities and sites as an inseparable entity: a Living Heritage Approach. This approach brings a new insight into key concepts such as authenticity and sustainable development. Through the use of the monastic site of Meteora, Greece, as a case study, the discussion generated aims to shift the focus of conservation from ‘preservation’ towards a continual process of ‘creation’ in an ongoing present, attempting to change the way heritage is perceived, protected and, more importantly, further created
Peak power reduction algorithms in asymmetric digital subscriber line modems
No full textThesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2000.Includes bibliographical references (leaves 94-96).This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.This thesis investigates peak-to-average ratio (PAR) reduction techniques for multicarrier modulation systems, such as discrete multitone (DMT) modems and orthogonal frequency-division multiplexed (OFDM) terrestrial broadcast transmitters. Through simulation and test implementation on a state-of-the-art programmable ADSL development platform, this thesis pursues a suitable solution for minimizing PAR given the resources of a programmable platform. This solution is integrated as a prototype implementation into a fully-functional ADSL modem and optimized for maximum PAR reduction performance within modem complexity constraints.by Athanasios Dimitri Dousis.M.Eng
Biochemistry and physiology of soccer
No full textThe inflammatory responses, oxidative stress rise and performance deterioration have been observed after one or more soccer games in season microcycle, lasting 72 hours. The purpose of the present study was to examine the effects of protein supplementation (80% casein & 20% Whey) on performance, muscle damage, inflammation and oxidative stress markers during a one in-season microcycle with two games. The recovery time between soccer games was 72 hours. Twenty healthy soccer players participated in two trials, receiving either milk protein concentrate (PRO: 1.15 and 0.26 g/kg on game and training days, respectively) or an energy-matched placebo (PLA: 1.37 and 0.31 g/kg of carbohydrate on game and training days, respectively) according to a randomized, repeated-measures, crossover, double-blind design. Each trial included two games and four daily practices. Speed (10m, 30m.) , jump height (CMJ), isokinetic peak torque, and muscle soreness (DOMS) of knee flexors (KF) and extensors (KE) were measured before G1 and daily thereafter for six days. Blood samples were drawn before and immediately post games and every day during the microcycle, in order to determine inflammation and oxidative stress markers. Field activity and heart rate were monitored using GPS technology during games and practices. The two games reduced speed (3-17%), strength of knee flexors (12-23%) and jump height (3-10%), during recovery period after games, in both trials. In high intensity running marker during soccer game, PRO trial restrict the decline compared to PLA trial (P= 0.012), for the second game in last 15 minutes (75-90 min.). No treatment effect was observed for delayed onset of muscle soreness, leukocyte counts, and creatine kinase activity. Furthermore, no treatment effect was observed, despite of the faster recovery of knee strength (KF, KE) and faster recovery of protein and lipid peroxidation markers in PRO trial, 48 hours after the second game. In summary, the protein supplementation improves soccer specific performance marker, promoting the faster recovery of knee strength.Μετά από έναν ή περισσότερους αγώνες ποδοσφαίρου κατά τη διάρκεια ενός αγωνιστικού μικρόκυκλου, παρατηρείται έντονη φλεγμονώδης αντίδραση, αύξηση των επιπέδων του οξειδωτικού στρες και πτώση της απόδοσης για 72 ώρες. Σκοπός της παρούσας διατριβής ήταν να εξετάσει τις επιδράσεις συμπληρώματος πρωτεΐνης (80% καζεΐνης & 20% ορού γάλακτος), σε δείκτες απόδοσης, μυϊκής βλάβης, φλεγμονής και οξειδωτικού στρες, κατά την διάρκεια ενός αγωνιστικού μικρόκυκλου με δύο ποδοσφαιρικούς αγώνες και με τη χρονική διαφορά μεταξύ του πρώτου και του δεύτερου αγώνα να είναι 72 ώρες. Στην διπλά τυφλή μελέτη με επαναλαμβανόμενες μετρήσεις, έλαβαν μέρος 20 υγιείς ποδοσφαιριστές, οι οποίοι συμμετείχαν σε δύο πειραματικές εβδομάδες, αφού χωρίστηκαν με τυχαιοποιημένο τρόπο. Οι ποδοσφαιριστές κατανάλωναν είτε πρωτεΐνη γάλακτος σε σκόνη (PRO: 1,15 γρ/κλ. την ημέρα του αγώνα και 0,26 γρ/κλ. τις ημέρες της προπόνησης) είτε εικονικό σκεύασμα παρόμοιας ενεργειακής απόδοσης (PLA: 1,37 γρ/κλ. την ημέρα του αγώνα και 0,31 γρ/κλ. τις ημέρες της προπόνησης). Κάθε πειραματική εβδομάδα περιελάμβανε δύο ποδοσφαιρικούς αγώνες και τέσσερις προπονήσεις. Η ταχύτητα (10μ., 30μ.), το άλμα (CMJ), η ισοκινητική μέγιστη ροπή και ο μυϊκός πόνος (DOMS) των καμπτήρων (KF) και των εκτεινόντων του γόνατος (KE), μετρήθηκαν πριν τον πρώτο αγώνα και κάθε μέρα για τις επόμενες έξι ημέρες. Ποσότητα αίματος συλλέχθηκε πριν και αμέσως μετά από κάθε αγώνα και για όλες τις επόμενες ημέρες προκειμένου να μετρηθούν δείκτες φλεγμονής και οξειδωτικού στρες. Οι δρομικές επιβαρύνσεις και η καρδιακή συχνότητα των αγώνων και τον προπονήσεων, κατεγράφησαν μέσω μονάδων GPS. Οι δύο αγώνες, μείωσαν την ταχύτητα (3-17%), την δύναμη των καμπτήρων (12-23%) και το άλμα (3-10%) κατά την διάρκεια της αποκατάστασης και στις δύο πειραματικές εβδομάδες. Στη συνθήκη PRO, για το τρέξιμο υψηλής έντασης παρατηρήθηκε μικρότερη μείωση σε σχέση με την συνθήκη PLA (P= 0.012) για το δεύτερο παιχνίδι στα τελευταία 15 λεπτά (75-90 λεπ.). Δεν παρατηρήθηκε καμία επίδραση της συμπληρωματικής λήψης στους δείκτες φλεγμονής (DOMS, αριθμός λευκοκυττάρων, κρεατινική κινάση). Παρά την ταχύτερη ανάκαμψη της δύναμης των εκτεινόντων και των καμπτήρων στη συνθήκη PRO, στις 48 ώρες μετά το δεύτερο παιχνίδι και των δεικτών οξείδωσης πρωτεϊνών και λιπιδίων, δεν εμφανίστηκε σημαντική διαφορά μεταξύ των δύο συνθηκών. Συνοπτικά, η συμπληρωματική λήψη πρωτεΐνης μπορεί να βελτιώσει την αγωνιστική απόδοση δημιουργώντας τις συνθήκες για ταχύτερη ανάκτηση της δύναμης

ABSTRACT: The decision of the ECtHR of 31.08.2023, Amvrosios-Athanasios Lenis v. Greece (no. 47833/20), is a further step toward an increasingly dense jurisprudence on “hate speech” and the limits of freedom of expression. The public proclamation of religious doctrines that are in conflict with the values of the contracting States enshrined in the ECHR is protected to a certain extent by the fundamental right of freedom of religion and belief. However, the qualification of a statement as religious does not justify “hate speech.” The AUTHOR shows the tension between freedom of religion, freedom of expression, and protection against discrimination, and analyzes the decision against the backdrop of Article 17 of the ECHR (prohibition of abuse of rights).

Economic complexity of cities and its role for resilience
No full textThe aim of the paper is to propose the construction of an index that captures the economic complexity of cities over the globe, as well as to explore whether it is a good predictor for a range of city-level economic outcomes. This index aspires to mitigate data scarcity for cities and to provide policy makers with the tools for monitoring the evolving role of cities in the global economy. Analytically, we implement the economic complexity methodology on data for the ownership, location and economic activities of the world’s 3,000 largest firms and their subsidiaries to propose a new indicator that quantifies the network of the largest cities worldwide and the economic activities of their globalized firms. We first show that complex cities are the highly diversified cities that host non-ubiquitous economic activities of firms with global presence. Then, in a sample of EU cities, we show that complex cities tend to be more prosperous, have higher population, and are associated with more jobs, human capital, innovation, technology and transport infrastructure. Last, using OLS methodology and accounting for several other confounders, we show that a higher ECI, at the city level, enhances the resilience of cities to negative economic shocks, i.e., their ability to bounce back after a shock. Specifically, we find that the expected increase of the ratio of employment in 2012 over 2006 is 0.01 (mean: 0.992; standard deviation: 0.081) when the ECI increases by 1 unit (mean: 0.371; standard deviation: 1.094), i.e., a satisfactory pace of recovery, in terms of employment. The ability to diversify in the presence of a shock, the reallocation of factors of production to other sectors and the ability to extract rents associated with those diversified activities, uncovers the mechanics of the ECI index
La tomba III di Haghios Athanasios e il valore semantico dell'incarnato
No full textThe tomb III at Haghios Athanasios stands out among the Macedonian tombs for the exceptional painted decoration of the temple-like façade. Excavated in the '90s by M. Tsimbidou-Avloniti it has been published by the scholar in full detail and the iconographic program of the monument has been the object of many publications. This article re-examines the different ways of reproducing the skin color (το ανδρείκελον) in the figures of the miniature frieze and in the megalographic figures beside the door. The realistic rendering of the megalographic figures of armed men in Macedonian attire, showing their sorrow for the lost of an etairos, is contrasting with the pale color of the participants to the symposion in the frieze above the door, a scene whose illusionistic overtone has been yet perceived by the critics. This symposion is articulated in three scenes and it can be interpeted as a necrodeipnon, but in the same time as a celebration of the Macedonian banquet style, centered on the royal court. The author suggests that the first figure on the right of the frieze, related to the group of armed men looking towards the banqueters feasting in the center of the frieze, can be read as the dead himself, for the particular rendering of his ανδρείκελον, showing the typical ochròtes or necròdes face color, according to the contemporary medical lexicon. The pathetic stance assumed by the same figure, the sole in the group which is not bearing arms, seems to confirm his role in the context of the scene
