Συγκριτική μελέτη των έσω μαστικών αρτηριών για την επιλογή τους ως μόσχευμα στην αορτοστεφανιαία παράκαμψη
Authors: Παλιούρας Δημήτριος
Published: August 2021

Οι έσω μαστικές αρτηρίες αποτελούν τα σημαντικότερα μοσχεύματα στην αορτοστεφανιαία παράκαμψη. Η μικρή διαφορά στην μακρόχρονη βατότητα της αριστερής και της δεξιάς έσω μαστικής αρτηρίας αποτέλεσε το έναυσμα για την μελέτη και σύγκριση των δύο αυτών αγγείων, τόσο ως προς ανατομικά στοιχεία και μετρήσεις, αλλά κυρίως ως προς την ιστολογική τους σύσταση από την έκφυση μέχρι τον διχασμό τους, με βάση την αναλογία μυϊκού, ελαστικού ιστού και κολλαγόνου. Από την μελέτη, προέκυψαν διαφορές ως προς την ιστολογική σύνθεση των αρτηριών, τόσο από την έκφυση μέχρι το διχασμό τους αλλά και διαφορές στην συγκριτική μελέτη αντιστοίχων τμημάτων της δεξιάς και αριστερής έσω μαστικής αρτηρίας ως προς την απόσταση από το στερνικό χείλος, διάμετρο, μήκος, κλάδους. Επίσης έγινε σύγκριση με παράγοντες όπως το βάρος, ύψος, φύλο, σακχαρώδη διαβήτης, υπέρταση, στεφανιαία νόσος, υπερλιπιδαιμία. Βρέθηκε υπεροχή του μυϊκού στοιχείου σε μεγαλύτερο βαθμό σε αντίστοιχα τμήματα της δεξιάς έσω μαστικής αρτηρίας, ενώ βρέθηκε υπεροχή του ελαστικού στοιχείου σε αντίστοιχα τμήματα της αριστερής σε σύγκριση με αντίστοιχα τμήματα της δεξιάς έσω μαστικής αρτηρίας. Ως προς το ποσοστό κολλαγόνου στη σύγκριση αντίστοιχων τμημάτων, εκτός από ένα τμήμα στο αρχικό τμήμα της έσω μαστικής, στα υπόλοιπα τμήματα που μελετήθηκαν φαίνεται υπεροχή του κολλαγόνου ιστού στην αριστερή έσω μαστική αρτηρία ως προς την σύγκριση με αντίστοιχα τμήματα της δεξιάς.

Το πλαστικό υλικό Piasti - Pore είναι σπόγγος από πολυαιθυλένιο πορώδους συστάσεως και υψηλής πυκνότητας, με πάρα πολύ καλή συμπεριφορά στο δύσκολο περιβάλλον του μέσου ωτός.Τα χαρακτηριστικά του να παραμένει σταθερό στον χρόνο, να είναι εύπλαστο και να μεταφέρει με ευκολία τον ήχο στο έσω ους, το κατέταξαν στα πιο δημοφιλή υλικό από το 1976 που πρωτοεμφανίστηκε μέχρι και σήμερα.Η μελέτη αυτή πραγματοποιήθηκε με σκοπό να ελεγχθούν τα ακουστικά αποτελέσματα, τα ποσοστά και τα αίτια απόρριψής του καθώς και τους παράγοντες εκείνους που μπορούν να επηρεάσουν το αποτέλεσμα μιας τέτοιας επέμβασης.Από τον έλεγχο 42 ασθενών που υπεβλήθησαν σε τυμπανοπλαστική, το 65% είχε επιτυχή ακουστικά αποτελέσματα ενώ το ποσοστό απόρριψης της προσθέσεως ήταν μόνο 4.9%. τα αποτελέσματα αυτά δεν μεταβλήθηκαν καθ’ όλη την διάρκεια της μελέτης. Η παρουσία ορισμένων παραγόντων συνδέθηκε άμεσα με το αποτέλεσμα, ενώ για κάποιους άλλους πιθανολογήθηκε, η συμμετοχή τους.Η ιδιότητα του υλικού αυτού, να δίνει την δυνατότητα στην ανάπτυξη συνδετικού ιστού ανάμεσα από τους πόρους, φαίνεται ότι έχει τον βασικό ρόλο στην διαμόρφωση των αποτελεσμάτων αυτών.Η σύγκρισή του με τα άλλα υλικά, το τοποθετεί ανάμεσα στις πρώτες επιλογές, για αυτού του είδους τις επεμβάσεις, αλλά παράλληλα δημιουργεί και τις προϋποθέσεις εκείνες που θα οδηγήσουν σε νέους σχε- διασμούς και στην ανάπτυξη καλλίτερων ακόμα υλικών.

Authors: Γιαννόπουλος Χρήστος
Published: August 2021

Κύριος στόχος της παρούσας εργασίας είναι να συμβάλλει με πρωτογενή ερευνητικά δεδομένα στη μελέτη του μάνατζμεντ στο περιβάλλον των Ελληνικών Δημοτικών Σχολείων. Η εργασία χωρίζεται σε δύο μέρη: Στο πρώτο παρουσιάζουμε βασικές έννοιες που άπτονται του «μάνατζμεντ εκπαιδευτικών οργανισμών» και αναλύουμε πέντε μοντέλα διαχείρισης και ηγεσίας εκπαιδευτικών οργανισμών. Στο δεύτερο μέρος παρουσιάζουμε την ερευνητική προσέγγιση του φαινομένου. Εξετάζουμε την άποψη των εκπαιδευτικών για βασικές αρχές του εκπαιδευτικού μάνατζμεντ καθώς και αναφορικά με την εμπράγματη και επιθυμητή σχολική λειτουργία σε σχέση με τον προσανατολισμό και τις κατευθύνσεις του μοντέλου διαχείρισης ίσης εξουσίας. Βασικοί άξονες της έρευνας είναι: Αρχές διαχείρισης εκπαιδευτικών οργανισμών, Δομή και λήψη αποφάσεων στο σχολείο (εμπράγματη και επιθυμητή κατάσταση), Περιβάλλον και σχολείο (εμπράγματη και επιθυμητή κατάσταση), Οριοθέτηση στόχων (εμπράγματη και επιθυμητή κατάσταση), Ηγεσία (εμπράγματη και επιθυμητή κατάσταση). Το δείγμα της έρευνας αποτέλεσαν 321 συμμετέχοντες (διευθυντές, υποδιευθυντές, δάσκαλοι) από 44 Δημόσια Δημοτικά σχολεία της γεωγραφικής περιοχής της Ηπείρου, ενώ εργαλείο συλλογής ερευνητικών δεδομένων ήταν το ερωτηματολόγιο. Η στατιστική ανάλυση χωρίζεται σε δυο μέρη: Το πρώτο αναφέρεται στην περιγραφική ανάλυση όπου παρουσιάζονται οι απόψεις των εκπαιδευτικών για κάθε μεταβλητή (πρόταση) της έρευνας, ενώ διεξάγεται και ανάλυση παραγόντων. Στο δεύτερο μέρος της στατιστικής ανάλυσης εξετάζουμε αν η άποψη των συμμετεχόντων για τους παράγοντες αυτούς επηρεάζεται από συγκεκριμένα δημογραφικά τους χαρακτηριστικά. Τέλος εξετάζεται εάν η άποψή τους για ένα εκ των παραγόντων συσχετίζεται με την άποψή τους για τους υπόλοιπους. Από την περιγραφική ανάλυση διαφαίνεται ότι οι εκπαιδευτικοί έχουν πολύ θετική άποψη για τις αρχές διαχείρισης, ενώ διαφαίνεται και η θετική τους στάση όσον αφορά στις κατευθύνσεις του μοντέλου διαχείρισης της ίσης εξουσίας. Τα αποτελέσματα της έρευνας ανέδειξαν 14 παράγοντες στους βασικούς ερευνητικούς άξονες. Από τη συγκριτική ανάλυση των παραγόντων αυτών προέκυψαν πολλές συσχετίσεις μεταξύ τους καθώς και σε σχέση με δημογραφικά χαρακτηριστικά των συμμετεχόντων στην έρευνα. Γενικά, προκύπτουν ελλείψεις της εμπράγματης σχολικής διαχείρισης σε σχέση με το μοντέλο διαχείρισης ίσης εξουσίας, καθώς και σε σχέση με την επιθυμητή από τους εκπαιδευτικούς σχολική λειτουργία. Παρόλα αυτά προκύπτουν κάποιες παράμετροι της σχολικής λειτουργίας οι οποίες δρουν υποστηρικτικά όσον αφορά στην εισαγωγή της επιστήμης του εκπαιδευτικού μάνατζμεντ και του μοντέλου διαχείρισης ίσης εξουσίας στο Ελληνικό εκπαιδευτικό σύστημα και στα Ελληνικά Δημοτικά σχολεία.
Η επιρροή της ψυχανάλυσης και η έννοια της συμμετρίας στη σύνθεση όπερας
Authors: Βαλέτ Ιωσήφ
Published: August 2021

Από την εποχή που ο Φρόυντ εισήγαγε την έννοια του ‘ασυνείδητου’, οι λιμπρετίστες άρχισαν να εντάσσουν ψυχικές συγκρούσεις και ψυχοπαθολογικές καταστάσεις σε διαφορετικά στυλ όπερας. Οι παθολογικές περιπτώσεις της Νεύρωσης, της Ψύχωσης και της Υστερίας - που αποτελούν τις πλέον τραυματικές καταστάσεις της ανθρώπινης ψυχής και περιγράφονται από τις θεωρίες του ‘Εγώ και του Εκείνου’, του ‘Ανοίκειου’, των ‘Οικογενειακών συμπλεγμάτων’, της ‘Παθολογίας της εκδίκησης’ και της ‘Σκιάς’ - ενέπνευσαν λιμπρετίστες και συνθέτες το πρώτο μισό του 20ου αιώνα. Ο 2ος Παγκόσμιος Πόλεμος έφερε τους συνθέτες πιο κοντά στην ουτοπία, την αυτοκαταστροφική πλευρά της ανθρώπινης ψυχής, οδηγώντας στον Ψυχρό Πόλεμο και τη διχοτόμηση της Ευρώπης. Αυτή η ρευστή περίοδος της δεκαετίας του '60 έκανε τους συνθέτες να απεικονίσουν το παράλογο και το εφιαλτικό χρησιμοποιώντας αριθμούς και συμμετρίες. Οι συμμετρίες πηγάζουν από τον εσωτερικό κόσμο των συνθετών, τον προσωπικό τρόπο κατανόησης των κειμένων και την ταύτιση των κειμένων με τις εμπειρίες τους ή ακόμα και με τα ψυχικά τραύματά τους. Εκφράσεις συμμετρίας και η γενικότερη υιοθέτηση των ιδανικών αναλογιών στην κατασκευή μελωδιών, αρμονίας, ηχοχρωμάτων και υφής ξυπνούν τη βαθύτερη ανάγκη του υποσυνείδητου για συμμετρίες που υπάρχουν στη φύση - όπως ο κατοπτρισμός, η αριθμητική πρόοδος και η χρυσή τομή. Στην όπερα Ego (2009) η ψυχανάλυση και η συμμετρία αποτελούν τους βασικούς πυλώνες. Το λιμπρέτο βασίστηκε στο ψυχαναλυτικό θεατρικό μονόπρακτο της Άλις Γκέρστενμπεργκ ‘Overtones’ (1915) που αναφέρεται στις θεωρίες του Φρόυντ για το δυϊσμό της ψυχής. Οι κεντρικοί ρόλοι είναι δύο καλλιεργημένες αλλά επιτηδευμένες γυναίκες (υπερεγώ) που αποδίδονται από τραγουδίστριες με τους παράλληλους - άξεστους εαυτούς τους (εκείνο), που αποδίδονται από ηθοποιούς. Με αυτόν το διαχωρισμό των χαρακτήρων το κοινό μπορεί και ακούει τις σκέψεις και τις επιθυμίες τους. Οι έννοιες του ‘ασυνείδητου’, του ‘ανοίκειου’ και η διαμάχη του ‘εγώ’ με το ‘εκείνο’ προβάλλονται μέσα από τη χρήση του βιμπράτο, τις αντιθέσεις στον τρόπο απαγγελίας και τραγουδιού, την ενορχήστρωση και το πέρασμα από το ‘φως στη σκιά’, το ανοίκειο των μη διατονικών κλιμάκων, των αρμονικών συστημάτων και της σημειογραφίας, αλλά και μέσα από τη χρήση της ετεροφωνίας. Η χρήση του ζωντανού βίντεο εξάπτει την ιδέα του ασυνείδητου. Η συμμετρία προβάλλεται μέσα από τη χρήση των δύο γλωσσών, το μοντέλο της ημιτονοειδούς κυματομορφής και του 2ου αρμονικού της (Π.Η.Κ.Ε.), τις επιμέρους συμμετρίες στη μακροδομή, τη χρήση μικρο-κανόνων, την οκτατονική συμμετρική κλίμακα, και τα κάθετα μοντέλα βασισμένα σε σύστημα άξονα συμμετρίας που οδηγούν σε διφορούμενες συγχορδίες ως αποτέλεσμα διαστηματικών προεκτάσεων παραγόμενων από κυκλική περιστροφή.

Published: August 2021

Background: It is critical to understand the factors that could affect the acceptance of the coronavirus disease 2019 (COVID-19) vaccine in the community. The aim of this study was to determine factors that could possibly affect the acceptance of Indonesian citizens of COVID-19 vaccination using a Technology Acceptance Model (TAM), a model how users come to accept and use a technology.

Methods: An online survey was conducted between the first and fifth of November, 2020. Participants were asked to respond to questions on acceptance, perceived usefulness, perceived ease of use, perceived religiosity towards, and amount of information about COVID-19. This study used the Technology Acceptance Model (TAM) as the framework to decide factors that affect vaccine acceptance. Structural Equation Model was employed to assess the correlation between all explanatory variables and vaccine acceptance. Mann-Whitney test and Kruskal-Wallis rank were employed to assess demographic factors associated with acceptance.

Results: In total, 311 responses were included for analysis. Our TAM model suggested that high perceived usefulness significantly increased COVID-19 vaccine acceptance and high perceived ease of use significantly increased the perceived usefulness. Perceived religiosity did not substantially affect vaccine acceptance. The amount of information on COVID-19 also did not significantly affect vaccine acceptance. Our data suggested that vaccine acceptance was associated with age, type of occupation, marital status and monthly income to some degree.

Conclusion: Since perceived usefulness affects vaccine acceptance, the government should focus on the usefulness of the vaccine when promoting the COVID-19 vaccine to Indonesian citizens. In addition, since perceived ease of use significantly affects users’ acceptance to COVID-19 vaccine, the easier to acquire the vaccine in the community, the higher chance that the citizens are willing to be vaccinated.
Introducing R as a smart version of calculators enables beginners to explore it on their own
Authors: Choudhary Krishna , Pico Alexander R.
Published: August 2021

Rapid technological advances in the past decades have enabled molecular biologists to generate large-scale and complex data with affordable resource investments, or obtain such data from public repositories. Yet, many graduate students, postdoctoral scholars, and senior researchers in the biosciences find themselves ill-equipped to analyze large-scale data. Global surveys have revealed that active researchers prefer short training workshops to fill their skill gaps. In this article, we focus on the challenge of delivering a short data analysis workshop to absolute beginners in computer programming. We propose that introducing R or other programming languages for data analysis as smart versions of calculators can help lower the communication barrier with absolute beginners. We describe this comparison with a few analogies and hope that other instructors will find them useful. We utilized these in our four-hour long training workshops involving participatory live coding, which we delivered in person and via videoconferencing. Anecdotal evidence suggests that our exposition made R programming seem easy and enabled beginners to explore it on their own.

Abstract. Wahidah BF, Afiati N, Jumari. 2021. Community knowledge of Amorphophallus muelleri Blume: Cultivation and utilization in Central Java, Indonesia. Biodiversitas 22: 2731-2737. Porang (Amorphophallus muelleri Blume) is a member of the Araceae edible family currently popular on Java island, Indonesia. In the last five years, this plant which has high economic value due to its various benefits as a food plant and medicinal plant has been cultivated in Central Java. This study aims to determine the knowledge of the people in Central Java about porang plant, its cultivation, and its use in people's lives. The method used is a qualitative method by applying data collection techniques through interviews, observation and documentation. Besides general interviews, this study gains more information from some informants whose purposively chosen amongst the respondents as people knowledgeable about porang in general, and in particular A. muelleri. Results showed that people in Central Java do have knowledge about porang plant even though it was not used as food ingredient. Public knowledge about porang cultivation is obtained from various sources including social media and people who strive for porang with success. Therefore, since the community is currently aware of the potential and economic values of porang, they have started to cultivate it. Porang has enormous potential to be developed in the future and provide welfare for the community.

Abstract. Moumeni L, Gastebois A, Gillmann L, Papon N, Benia F, Bouchara J-P, Bounechada M. 2021. Investigating the prevalence of Bark beetles of Pinus halepensis in the North East semi-arid region of Algeria. Biodiversitas 22: 2755-2762. Aleppo pine is the most common tree in the semi-arid forests of Algeria. Despite its high resistance to drought and adaptability to all types of soils, the effects of climate change are affecting it directly and indirectly. Stressed trees indeed are subject to bark beetle attacks. In this study, we sampled the bark beetles directly from the affected pine trees. Six species belonging to the Scolytinae subfamily were identified. Tomicus detruens and Orthotomicus erosus were widely spread and present in the three studied forests, where they were found to colonize living trees while Crypturgus numidicus, Crypturgus mediterraneus, Hylurgus ligniperda and Hylurgus micklitzi colonized only dead trees. Together with future identification of the microfungi associated with these xylophagous insects, these data may help to define prevention measures to fight the decline of Aleppo pine forests observed in some parts of Eastern Algeria.

Abstract. Puspitarini RD, Fernando I, Setiawan Y, Anggraini D, Rizqi HA. 2021. Short Communication: First record of the cassava lace bug Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) from East Java, Indonesia. Biodiversitas 22: 2870-2876. The cassava lace bug, Vatiga illudens (Drake, 1922) (Hemiptera: Heteroptera: Tingidae) is recorded from Indonesia for the first time. This species is found on the abaxial surface of leaves of cassava (Manihot esculenta Crantz, Euphorbiaceae) in several plantations of East Java and heavily infest this plant. Vatiga illudens is native to the Neotropical Region and seems to be the alien species in the Oriental Region. This tingid has already spread over a wide region of East Java, suggesting that the invasion of the lace bug endangers the other regions cultivating cassava.

Abstract. MeinataA, Na’iem M, Adriyanti DT, Syahbudin A. 2021. Short communication: Leaf architecture of 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes in Carita, Banten, Indonesia. Biodiversitas 22: 2952-2960. Dipterocarpaceae is a major commercial timber characterized by high unbranched bole, paired stipules, and winged fruit. The identification process in the family becomes problematic, in cases where the generative organ is absent. Therefore, a new approach needs to be established to address any misidentification leading to improper utilization. This study aims to determine the leaf architecture in 35 species of Dipterocarpaceae cultivated in Forest Area with Special Purposes (KHDTK) Carita, Banten, Indonesia. The ten leaf samples collected were the third and fourth leaves from terminal shoots of a single tree of each species. Subsequently, the data were observed and measured based on the 17 morphological characters. Each character was then scored and analyzed using multivariate analyses cluster to determine the relationship between species. Dipterocarpaceae generally has pinnate leaf category, geniculate petiole, and entire margin. Furthermore, the phenon line in the dendrogram is cut at 0.695 similarity level to establish meaningful interpretation. The 35 species observed were grouped into 4 major clusters. Small leaf group, inconsistent tertiary vein pattern group, symmetrical leaves with cordate base leaf group, and other groups that do not resemble mentioned characters. The key determination comprised 34 couplets with three characters repeated due to limited descriptors.

Abstract. Adjahossou VN, Gbemavo DSJC, Abidja S, Laly J, Gbaguidi AA, Anagonou AD. 2021. Folk classification and traditional uses of Cyperus esculentus, a neglected and underutilized species in Benin. Biodiversitas 22: 2972-2979. The sweet pea or tigernut (Cyperus esculentus L.) has very high potential to be developed but is considered a neglected and underutilized plant in Benin. The current study aims to investigate the indigenous knowledge related to local diversity, production and uses of various landrace types of tigernut grown in its production areas in Benin. Using Participatory Research Appraisal (PRA) method, we surveyed 113 tigernut farmers in different regions of production in Atacora Department, Benin. Univariate statistics were performed to describe and compare tigernut farmers' responses on botanical and agronomic criteria. We found that the tigernut farmers in the studied area distinguished three landraces of C. esculentus. Two landrace types produced yellow-skinned tubers and the other produced black-skinned tubers. Economic value, agro-morphological traits and organoleptic quality were the criteria considered by the farmers when choosing the type of landrace to cultivate. According to the farmers, the attacks of the tubers by earthworms and termites constituted the main constraints of the production of tigernut. Local people used the species mainly for food, while small proportion was for medicine (e.g., for aphrodisiac) and soil fertilization purposes. This study implies that C. esculentus in Benin deserves better attention to be conserved and developed.

A comprehensive taxonomic study and three new records of genus Geostachys (Baker) Ridl. in Thailand have not been reported. This research aimed to study the taxonomical aspect of the genus Geostachys in Thailand based on herbarium collections, fresh materials, and available literatures. Nine species of Geostachys have been recognized with their updated nomenclature in Thailand, namely G. angustifolia K. Larsen, G. chayanii Mayoe, G. decurvata (Baker) Ridl., G. holttumii K. Larsen, G. kerrii K. Larsen, G. penangensis Ridl., G. pierreana Gagnep., G. smitinandii K. Larsen, and. G. tratensis Picheans. & Mayoe. Three species, namely G. decurvata, G. pierreana, and G. penangensis are found to be new records to Thailand. Six species, namely G. angustifolia, G. chayanii, G. holttumii, G. kerrii, G. smitinandii, and G. tratensis were endemic to Thailand. The identification key to species, detailed descriptions, photographs, vernacular name, geographical distribution, ecology, phenology, conservation status, and taxonomic notes have been provided.

Abundance, diversity and daily activity of terrestrial mammal and bird species in disturbed and undisturbed limestone habitats using camera trapping, Central Thailand. Biodiversitas 22: 3620-3631.  This study on the abundance, diversity and daily activity of terrestrial mammal and bird species was conducted in the limestone mountainous area of Central Thailand, located on the east of Dong Phaya Yen-Khao Yai forest complex. Camera traps were placed in both habitats disturbed by limestone mining and undisturbed habitat areas. From the study, a total of 38 species of mammals and birds from 27 families in 13 orders were recorded, including 15 species of mammals from 6 orders, 12 families and 23 species of birds from 14 families in 7 orders. Fifteen species of mammals were recorded in the undisturbed area and 11 were recorded in the disturbed area, with the Malayan Pangolin, Small Indian Civet and Grey-bellied Squirrel found in the undisturbed area. However, the number of bird species in the limestone mining area was larger than in the undisturbed area. It was also found that there was no difference in the overall abundance and diversity of mammalian species between disturbed and undisturbed areas, which is not in accordance with the hypothesis. But in the case of wild birds, the relative abundance of wild birds was found to differ significantly between areas. A high number was found in the areas with mining activities, although there was no difference in the diversity index of the two areas. However, it was found that when the combined data was analyzed, there was a significant difference in the daily activity of both mammals and wild birds in both areas. Many rare wildlife species were recorded during this study, for example, the Malayan Pangolin, Serow, Northern Pig-tailed Macaque, Rufous Limestone-babbler, Golden Jackal, Leopard Cat, Large-toothed Ferret Badger, Small Asian Mongoose, Common Palm Civet, Small Indian Civet, Malayan Porcupine. The key measure proposed is to preserve some natural habitats within the areas with mining activities, as wildlife remains in the area.
Toxic adenoma: to biopsy or not to biopsy?
Authors: Goonoo MS , Arshad MF , Tahir F , Balasubramanian SP
Published: August 2021

Toxic adenoma nodules rarely harbour cancer. Fine-needle aspiration (FNA) is often not done because of the rarity of these lesions being cancer, the difficulty in interpreting cytology in hyperthyroid patients and the rare precipitation of thyrotoxicosis. We present two young, Caucasian female patients aged 29 and 13 years who were each diagnosed with a toxic nodule categorised as benign and indeterminate respectively. They underwent hemithyroidectomy after being rendered euthyroid, however their histology unexpectedly revealed differentiated follicular cancer. Despite thyroid cancer being rare in patients with toxic adenomas, it should be considered when planning treatment, especially if there are risk factors for cancer, or suspicious features on ultrasound examination. A review of the literature shows that compared with adenomas in euthyroid patients, patients in this group are generally younger and predominately female. If an FNA is considered, it should be performed after the patient is rendered euthyroid.

Ulceration of the oral cavity is common and a frequent reason for referral to secondary and tertiary centres. Epstein–Barr virus (EBV)-related mucocutaneous ulceration, however, is a rare cause of oral ulceration that has been described only recently. Histologically these lesions resemble lymphomas; however, their management and prognosis differ significantly. We present a case of EBV-induced oral ulceration and discuss the diagnosis and management of and available literature for the condition, which was treated successfully through conservative measures alone.
‘Mind if I record this?’ Patients making audio-visual recordings of consultations: a survey of surgeons’ experiences
Authors: Magowan D , Burton L , Williams GL , Khurana A
Published: August 2021

Introduction

Audio-visual recordings made by patients of their clinical encounters are increasingly common. This may be done with or without their doctors’ knowledge or consent and is considered admissible legal evidence. Many surgeons may feel uncomfortable with being recorded and lack knowledge regarding the legal implications. The aim of this study was to gauge how surgeons react to being recorded, and what specific medico-legal insight they have regarding these matters.

Methods

In total, 150 surveys were distributed to surgeons in two hospitals in South Wales by email, Survey Monkey and paper copy between 28 October 2019 and 9 March 2020. The survey was anonymous and recorded level of training, as well as four simple questions regarding how surgeons may react to being recorded and what they felt their legal rights were.

Results

There were 91 respondents: 28 consultants, 36 registrars and 27 junior surgical trainees. Of the respondents, 56% were uncomfortable with being recorded and 23% would stop a consultation if their patient insisted on recording it. These issues were most marked for junior surgical trainees. Sixty-two per cent of respondents were unaware of their legal rights and 21% believed they were legally able to refuse to continue a consultation. This belief was particularly marked among consultants.

Conclusion

Many surgeons are uncomfortable with being recorded and lack knowledge regarding their medico-legal standing. Education and guidance from the Royal Colleges would help address this issue and avoid misunderstanding when surgeons are faced with these potentially difficult scenarios.
Weed seed contamination in imported seed lots entering New Zealand

Published: August 2021

Imports of seeds for sowing are a major pathway for the introduction of contaminant seeds, and many agricultural weeds globally naturalised originally have entered through this pathway. Effective management of this pathway is a significant means of reducing future plant introductions and helps minimise agricultural losses. Using a national border inspection database, we examined the frequency, origin and identity of contaminant seeds within seed for sowing shipments entering New Zealand between 2014–2018. Our analysis looked at 41,610 seed lots across 1,420 crop seed species from over 90 countries. Overall, contamination was rare, occurring in 1.9% of all seed lots. Among the different crop types, the arable category had the lowest percentage of seed lots contaminated (0.5%) and the forage category had the highest (12.6%). Crop seeds Capsicum, Phaseolus and Solanum had the lowest contamination rates (0.0%). Forage crops Medicago (27.3%) and Trifolium (19.8%) had the highest contamination rates. Out of 191 genera recorded as contaminants, Chenopodium was the most common. Regulated quarantine weeds were the rarest contaminant type, only occurring in 0.06% of seed lots. Sorghum halepense was the most common quarantine species and was only found in vegetable seed lots. Vegetable crop seed lots accounted for approximately half of all quarantine species detections, Raphanus sativus being the most contaminated vegetable crop. Larger seed lots were significantly more contaminated and more likely to contain a quarantine species than smaller seed lots. These findings support International Seed Testing Association rules on maximum seed lot weights. Low contamination rates suggest industry practices are effective in minimising contaminant seeds. Considering New Zealand inspects every imported seed lot, utilises a working sample size 5 times larger than International Seed Testing Association rules require, trades crop seed with approximately half of the world’s countries and imports thousands of crop seed species, our study provides a unique overview of contaminant seeds that move throughout the seed for sowing system.
Evaluation of molecular characterization and phylogeny for quantification of Acanthamoeba and Naegleria fowleri in various water sources, Turkey
Authors: Aykur Mehmet , Dagci Hande
Published: August 2021

Free-living amoeba (FLA) is widely distributed in the natural environment. Since these amoebae are widely found in various waters, they pose an important public health problem. The aim of this study was to detect the presence of Acanthamoeba, B. mandrillaris, and N. fowleri in various water resources by qPCR in Izmir, Turkey. A total of (n = 27) 18.24% Acanthamoeba and (n = 4) 2.7% N. fowleri positives were detected in six different water sources using qPCR with ITS regions (ITS1) specific primers. The resulting concentrations varied in various water samples for Acanthamoeba in the range of 3.2x105-1.4x102 plasmid copies/l and for N. fowleri in the range of 8x103-11x102 plasmid copies/l. The highest concentration of Acanthamoeba and N. fowleri was found in seawater and damp samples respectively. All 27 Acanthamoeba isolates were identified in genotype level based on the 18S rRNA gene as T4 (51.85%), T5 (22.22%), T2 (14.81%) and T15 (11.11%). The four positive N. fowleri isolate was confirmed by sequencing the ITS1, ITS2 and 5.8S rRNA regions using specific primers. Four N. fowleri isolates were genotyped (three isolate as type 2 and one isolate as type 5) and detected for the first time from water sources in Turkey. Acanthamoeba and N. fowleri genotypes found in many natural environments are straightly related to human populations to have pathogenic potentials that may pose a risk to human health. Public health professionals should raise awareness on this issue, and public awareness education should be provided by the assistance of civil authorities. To the best of our knowledge, this is the first study on the quantitative detection and distribution of Acanthamoeba and N. fowleri genotypes in various water sources in Turkey.

Crítica pionera de Pedro Francisco Bonó a la idea de progreso en la segunda mitad del siglo XIX.
Authors: Minaya Santos Julio
Published: August 2021

Este artículo de investigación propone examinar, mediante una metodología cualitativa, el cuestionamiento de Pedro Francisco Bonó sobre la concepción salvífica de progreso que caracterizó al ambiente sociopolítico e intelectual de la sociedad dominicana en la segunda mitad del siglo xix. Como referente histórico-social de su discurso crítico sobre el ideal progresista, el pensador social aborda la irrupción del capital monopólico europeo sobre un país que recién acaba de emanciparse de España y se empeña infructuosamente en establecer instituciones cónsonas con el Estado nación. Entre los obstáculos señalados figuran el analfabetismo y la ignorancia, la mentalidad colonial, la corrupción política y las prácticas neocoloniales. Sin embargo, el intelectual crítico advierte que otro de los graves males es la teoría de progreso, enarbolada febrilmente por liberales y positivistas. Los resultados del presente análisis explican las argumentaciones al respecto, a la vez que se analizan las diversas etapas de la conceptualización de Bonó en torno al despliegue de dicha categoría por el entramado social dominicano.
Rhetoric between historical fiction and reality: the controversia in Fronto's correspondence
Authors: Margiotta Giovanni
Published: August 2021

In ancient education, controversia was a form of declamation which engaged students in discussion of a fictional judicial case. As the apex of rhetorical training, it provided a high level of proficiency in composition and delivery techniques, and every young man of the Roman upper-class had to deal with this exercise and its deliberative counterpart (suasoria). This article explores the role of controversia within the didactic programme devised by Cornelius Fronto for Marcus Aurelius’ education. After an account of ‘indirect’ approaches to declamation, I will analyse the themes of controversia assigned by Fronto, outlining their historical and rhetorical background.
Model of above-ground biomass distribution of Norway spruce (Picea abies L. (Karst.))
Authors: Krišāns Oskars , Samariks Valters , Matisons Roberts , Jansons Āris
Published: August 2021

Climate change with more frequent extreme weather events and prolonged winter periods with un-frozen, wet soil is causing frequent wind damage events in forests. Trees with higher mass point and heavier weight are more prone to wind damage; however, limited information exists on distribution of biomass under naturally moist conditions. Such information is essential to improve models of wind damage prediction. Therefore, the aim of the present study was to assess the biomass distribution and the parameters important for wind-load of Norway spruce (Picea abies (L.) Karst.). Samples were collected in the year 2019 from 87 trees growing on two different sites, corresponding to freely drained mineral and peaty mineral soils at the age of 55 and 88 years, respectively. Tree diameters at breast height, height, and height of first living branch were measured. Tree stems were pruned and cut into 2-m-long fragments and weighed (fresh weight) afterwards. A biomass distribution model was developed to estimate fresh weight of the stem of Norway spruce using easy measurable tree variables. Relative height of the mass point and height of living branches were higher in peaty mineral soil than on freely drained mineral soil, which was an indicator for higher windthrow risks.
Structural differences between reaction wood and opposite wood with different drying temperatures
Authors: Klement Ivan , Vilkovská Tatiana , Vilkovský Peter , Hýsek Štěpán
Published: August 2021

Reaction wood is characterized by having different anatomical and chemical features than normal wood. The different composition of cell walls, the higher quantitative proportion of thick-wall fiber cells, diameter, and the abundance of vessels have remarkable effects on reaction wood’s physical and mechanical properties. Reaction wood has fewer vascular cells. In addition, it has a smaller lumen diameter, which results in reduced permeability. Therefore, reaction wood is more difficult to dry at a certain moisture content. The differences in the drying times of the reaction wood and the normal wood were largest at a temperature of 60 °C and durations greater than 30 h, and the reaction wood dried more slowly. At a temperature of 120 °C, the differences in drying time were minimalized, and drying end times were almost identical. The expected negative effect of higher temperature on the morphology of reaction wood and opposition wood was not confirmed.
Fiber fines for fabricating lignocellulose films and the effect of lignin
Authors: Pourjafar Mohammad , Khosravani Amir , Behrooz Rabi
Published: August 2021

Excess lignocellulose fines in some fiber processing mills cause issues and hurt product quality. To use this type of biomaterial as a resource, surplus fines can be separated and dissolved with solvents for further transformation. Therefore, 1-butyl 3-methyl imidazolium chloride ionic liquid (IL) was used as a powerful green solvent for a rapid dissolution process. However, a low degree of polymerization (DP) of the cellulose in fines and the effects of lignin content and its structure on the process and film properties are controversial subjects. This study demonstrated that the three dimensional structure of lignin did not permit the raw bagasse fines (prior to pulping) to dissolve in the IL even after several hours. However, following decomposition of the lignin structure by pulping, the fiber fines were readily dissolved. Further, all the fabricated films from the fiber fines exhibited satisfactory strength properties, despite the fact that the cellulose had a low DP. The films from bleached fiber fines showed higher tensile strength than those containing lignin, although the cellulose chain was longer and had a higher DP for the latter. Lignin resulted in reduced transparency, and higher absorption of ultraviolet radiations, but it did not affect the surface roughness of the films.

A combined control system for a shunt active filter in the coordinate system of the two-wattmeters method has been proposed, which, depending on the conditions of use, implements one of the four active filtration strategies, optimal according to a certain quality indicator. The most promising is the proposed integral strategy for active filtration control with the reference vector of line voltages of direct sequence, which provides symmetric sinusoidal currents of the network and the minimum pulsation of power consumption for the almost identical energy-saving effect as the concept of S. Fryze. New formulas for calculating the energy-saving effect and pulsations of the instantaneous power in a three-phase system of power in the case of the formation of an active current in the transmission line in the conditions of asymmetry of loading voltage and linear asymmetric load have been developed. Simulation studies have confirmed the adequacy of the proposed strategies and calculations. References 15, figures 5, tables 2.

Linfoma primario de cuello uterino. Reporte de caso
Authors: González Mariño Mario Arturo
Published: August 2021

Introducción. El linfoma primario del cuello uterino es una patología infrecuente, de síntomas inespecíficos y que pocas veces altera el examen de citología del cuello uterino dado que se desarrolla en el estroma cervical. Para su tratamiento existen varias opciones, incluyendo quimioterapia, radioterapia y cirugía, así como combinaciones de estas. La localización única del linfoma en el cuello uterino se considera un factor de buen pronóstico.
Presentación del caso. Paciente femenina de 49 años, quien consultó por dolor pélvico y flujo y sangrado genital. Se ordenó colposcopia por reporte de ASC-H (células escamosas atípicas que no excluyen lesiones intraepiteliales de alto grado) en citología vaginal. La biopsia reportó linfoma difuso de células B grandes, el cual se trató con rituximab, ciclofosfamida, doxorrubicina, vincristina y prednisolona por tres ciclos, y con rituximab, ifosfamida, carboplatino y etopósido por dos ciclos; este cambio se hizo debido a una mala respuesta con el primer esquema. Se realizó nueva biopsia después del último ciclo de quimioterapia con reporte de pólipo de tipo endocervical y abundantes grupos de células glandulares con atipia focal. Los estudios de imágenes diagnósticas posteriores al tratamiento reportaron engrosamiento concéntrico de la unión entre cuello uterino y vagina. A los 7 años del diagnóstico del linfoma se realizó otra biopsia que resultó negativa para displasia o malignidad. Al momento de la elaboración del presente reporte, 10 años después del diagnóstico, la paciente se encontraba asintomática y libre de enfermedad.
Conclusiones. El linfoma primario del cuello uterino es una patología rara que en pocas oportunidades se evidencia con anormalidad en la citología vaginal como en el caso reseñado. Dado este hallazgo se realizó una colposcopia mediante la cual se confirmó el diagnostico de linfoma difuso de células B grandes. Se presenta un caso con evolución satisfactoria y supervivencia libre de enfermedad después de 10 años.
Antagonismo de rizobacterias sobre hongos fitopatógenos, y su actividad microbiana con potencial biofertilizante, bioestimulante y biocontrolador
Authors: Blanco Carrero Erika Lorena , Castro Molina Yulimar
Published: August 2021

Las rizobacterias forman parte de la gran cantidad de microorganismos que actúan como agentes de biocontrol, produciendo metabolitos que inducen resistencia sistémica en las plantas que inhiben el crecimiento de patógenos. El objetivo de esta investigación fue evaluar la capacidad de diez rizobacterias de los géneros Rhizobium, Bradyrhizobium, Sinorhizobium, Ochrobactrum y Pseudomonas para producir ácido cianhídrico (HCN), sideróforos y ácido indol-acético (AIA), disolver fosfato, fijar nitrógeno e inhibir el crecimiento de fitopatógenos. Se realizaron todas las pruebas fisiológicas y bioquímicas correspondientes, así como la prueba de antagonismo in vitro contra los fitopatógenos Fusarium oxysporum, Colletotrichum gloeosporioides y Rhizoctonia solani.  Cinco cepas produjeron una mayor cantidad de AIA en relación a las otras en presencia de triptófano, la cepa ES1 (Ochrobactrum sp.) produjo HCN, el 50 % de las cepas evaluadas liberaron sideróforos, el 60 % disolvió fósforo, y todas resultaron positivas para la fijación de nitrógeno. Nueve cepas inhibieron el crecimiento de F. oxysporum entre 40 % y 65 %, la cepa Alf (Pseudomonas fluorescens) inhibió además el crecimiento de C. gloeosporioides en un 22 %, y ninguna inhibió el crecimiento de R. solani. Los rizobios evaluados y la cepa de Pseudomonas fluorescens podrían ejercer efectos beneficiosos sobre las plantas a través de mecanismos directos e indirectos, o una combinación de ambos, lo que las convierte en una opción sostenible para la producción de cultivos.
Prevalencia y factores de riesgo del comportamiento anormal estereotipado aerofagia en el caballo criollo colombiano
Authors: Patiño Marulanda J. J. , Vélez Gil S. A. , Martínez Aranzales J. R.
Published: August 2021

La aerofagia es la estereotipia clásica más común en los equinos, con una etiología poca entendida; sin embargo, se reconoce por ser de naturaleza multifactorial. Además, se ha asociado con efectos negativos sobre la salud de los equinos portadores. El objetivo de este estudio fue describir los factores de riesgo y la frecuencia de presentación de la aerofagia en una población de caballos criollos colombianos (ccc). Fueron encuestados 42 criaderos, entre los que se presentó un total de 1063 ccc (488 machos y 575 hembras). De esta población, el 5,27% (56 animales) fue plenamente identificado con aerofagia. Esta prevalencia fue superior a la mayoría de otros reportes de Sur América. La aerofagia, posiblemente obedeció tanto a factores inherentes al animal como a factores externos relacionados con el manejo; sin embargo, se requiere el diseño de estudios longitudina- les sobre prácticas de manejo y de líneas dentro de la raza para cuantificar y validar la información relacionada con la posible predisposición genética o racial a la aerofagia y a otras estereotipias y comportamientos anormales observados en estos animales.
