Nutritional Aspects of Bone Health and Fracture Healing
No full textIntroduction. Fractures are quite common, especially among the elderly. However, they can increase in prevalence in younger ages too if the bone health is not good. This may happen as a result of bad nutrition. Methods. A customized, retrospective review of available literature was performed using the following keywords: bone health, nutrition, and fractures. Results. Insufficient intake of certain vitamins, particularly A and D, and other nutrients, such as calcium, may affect bone health or even the time and degree of bone healing in case of fracture. The importance of different nutrients, both dietary and found in food supplements, is discussed concerning bone health and fracture healing. Conclusion. A healthy diet with adequate amounts of both macro- and micronutrients is essential, for both decreasing fracture risk and enhancing the healing process after fracture. © 2017 Athanasios Karpouzos et al

Ανατομικές παραλλαγές του αορτικού τόξου και των κλάδων αυτού
No full textΑπό τη μελέτη των δικών μας περιπτώσεων (8 περιπτώσεις σε 5 άνδρες και 3 γυναίκες): * 2 περιπτώσεις έκτοπης δεξιάς υποκλείδιας αρτηρίας με οπισθοοισοφαγική πορεία * 2 περιπτώσεις όπου η αριστερή σπονδυλική αρτηρία εκφυόταν από το αορτικό τόξο * 3 περιπτώσεις κοινού στελέχους της ανώνυμης αρτηρίας με την αριστερή κοινή καρωτίδα αρτηρία και * 1 περίπτωση αριστερής εντόπισης του βραχιονοκεφαλικού στελέχους με επιμήκυνση και υψηλή θέση σε σχέση με την τραχεία και της ανασκόπησης της επί του θέματος σχετικής διεθνούς βιβλιογραφίας συμπεραίνεται ότι η εμβρυολογική ερμηνεία των ανατομικών παραλλαγών του αορτικού τόξου και των κλάδων αυτού δύναται να θεωρηθεί σήμερα ως σχεδόν πλήρως μελετημένη. Οι περισσότερες των παραλλαγών αυτών παρουσιάζουν ανατομικό και εμβρυολογικό μόνο ενδιαφέρον, άλλες όμως και ειδικά αυτές που σχηματίζουν αγγειακό δακτύλιο γύρω από την τραχεία και τον οισοφάγο παρουσιάζουν κλινικό και χειρουργικό ενδιαφέρον. Δεδομένης της σχετικά υψηλής συχνότητας (περίπου 15%) εμφάνισης των παραλλαγών αυτών, θα πρέπει να λαμβάνονται υπόψη: α) στη χειρουργική της βάσης του τραχήλου και του άνω τμήματος του μεσοθωρακίου β) σε ασθενείς συμπτωματικούς πρέπει να διερευνάται αγγειογραφικά το αορτικό σύστημα και δια της εγχύσεως σκιαγραφικής ουσίας ο οισοφάγος και η τραχεία. Εναπόκειται δε στην κρίση του κλινικού ιατρού, η αξιολόγηση των ακτινογραφικών ευρημάτων σε συσχέτιση με τη συμπτωματολογία για το ενδεχόμενο χειρουργικής διευθέτησης.From the study of our cases (8 cases in 5 males and 3 females): - 2 cases of ectopic right subclavian artery with a retroesophageal course (ARSCA) - 2 cases in which the left vertebral artery (LVA) originated from the aortic arch - 3 cases of common stem of the brachiocephalic trunk (BCT) with the left common carotid artery (LCCA) - 1 case of a left-sided brachiocephalic trunk (BCT) with a characteristic elongation and a high position relative to the trachea and after a detailed literature review it is concluded that the embryological interpretation of the aortic arch anatomical variants and its branching pattern can be regarded as almost fully studied. Most of these variants are of an anatomical and embryological interest and others, especially the cases in which a vascular ring is created around the trachea and esophagus, are of clinical and surgical interest. Given the relatively high frequency (approximately 15%) of these variants, they should be taken into account: a) In the surgery of neck and the upper part of the mediastinum b) In symptomatic patients, the aortic arch should be angiographically investigated, as well as the esophagus and trachea after the injection of contrast agents. Clinician should consider the possibility of a surgical manipulation taking into account the existed symptomatology and radiographical evidence
Anatomic study and variations of the Adamkiewicz arterty and relations with the lumbar tuberosity
No full textIn this anatomical research, twenty human cadaveries were studied by the researcher. Out of these, twelve were women cadavers and eight of them were men. Those cavaders are used in the training of the second year students of the Medical School of University of Athens.Also eight cases of spinal cord blood supply from Anatomical Museum samples were used. Three of those samples were from men cadavers and five of women.In the current study, two variations of the artery of Adamkiewicz were found during cadavers dissection. The meticulous knowledge of this arterial variants is of paramount importance for the surgeons intervening in the thoracolumbar area. The artery's lesion or injury or obstruction may lead to loss of urinary and fecal continence as well as to weakness and paralysis of the lower limbs (paraplegia).Στην παρούσα ανατομική μελέτη, ο ερευνητής μελέτησε είκοσι (20) ανθρώπινα πτώματα, που χρησιμοποιούνται για την εκπαίδευση των Β'ετών φοιτητών της Ιατρικής Σχολής Αθηνών. Από τα ανθρώπινα πτώματα, τα δώδεκα (12) ήταν γυναίκες και τα οκτώ (8) ήταν άνδρες.Επίσης χρησιμοποιήθηκαν και 8 περιπτώσεις αιμάτωσης του Νωτιαίου Μυελού από Μουσειακό υλικό εκ των οποίων οι 3 ήταν άνδρες και οι 5 γυναίκες.Στην παρούσα μελέτη, δύο παραλλαγές της αρτηρίας του Adamkiewicz βρέθηκαν κατά τη διάρκεια της ανατομής των πτωμάτων. Η λεπτομερής γνώση της ανατομίας αυτών των αρτηριακών παραλλαγών είναι υψίστης σημασίας για τους χειρουργούς που επεμβαίνουν στην θωρακο-οσφυική περιοχή. Βλάβη της αρτηρίας, τραυματισμός ή παρεμπόδιση αυτής μπορούν να οδηγήσουν σε απώλεια ούρων και κοπράνων, όπως επίσης και να προκαλέσουν μυική αδυναμία έως και παράλυση των κάτω άκρων (παραπληγία)

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
Homophobic Statements, a Bishop, and the Limits of Freedom of Expression. An In-Depth Commentary on ECtHR 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20
No full textDichiarazioni omofobe, un vescovo e i limiti della libertà di espressione. Un commento approfondito su CEDU 31.08.2023, Amvrosios-Athanasios Lenis v. Greece, no. 47833/20.
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).

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
Computational Modelling of Compaction in Asphaltic Mixtures and Geomaterials
No full textAsphaltic mixtures are heterogeneous composite materials consisting of aggregates coated and bound by asphalt binder. The long term performance of asphaltic pavements is highly dependent on the mechanical behaviour of the asphaltic mixture during construction (mixing and compaction) and operation; inadequate mixture compaction leads to faster moisture and oxygen diffusion, ravelling, rutting and poor fatigue life
