Amoxicillin chewable tablets intended for pediatric use: formulation development, stability evaluation and taste assessment

To cover the unpleasant taste of amoxicillin (250 mg), maize starch (baby food) and milk chocolate were co-formulated. The raw materials and the final formulations were characterized by means of Dynamic Light Scattering (DLS), Differential Scanning Calorimetry (DSC) and Fourier-Transform Infrared (FT-IR) spectroscopy. To evaluate the taste masking two different groups of volunteers were used, according to the Ethical Research Committee of the Aristotle University of Thessaloniki. The optimization of excipients’ content in the tablet was determined by experimental design methodology (crossed D-optimal). Due to the matrix complexity, amoxicillin was extracted using liquid extraction and analyzed isocratically by HPLC. The developed chromatographic method was validated (%Recovery 98.7–101.3, %RSD = 1.3, LOD and LOQ 0.15 and 0.45 μg mL−1 respectively) according to the International Conference on Harmonization (ICH) guidelines. The physicochemical properties of the tablets were also examined demonstrating satisfactory quality characteristics (diameter: 15 mm, thickness: 6 mm, hardness <98 Newton, loss of mass <1.0%, disintegration time ∼25min). Additionally, dissolution (%Recovery >90) and in vitro digestion tests (%Recovery >95) were carried out. Stability experiments indicated that amoxicillin is stable in the prepared formulations for at least one year (%Recovery <91).

P–400 Endometrial changes in estrogen and progesterone receptor expression during implantation in an oocyte donation program

Abstract Study question Which are the endometrial changes during implantation in assisted reproduction techniques? Summary answer Synchronization between blastocyst development and the acquisition of endometrial receptivity is a prerequisite for the success of in vitro fertilisation (IVF). What is known already Implantation is the final and most important stage of embryogenesis and is of paramount importance in achieving a successful pregnancy. Progesterone and estrogen are steroid hormones responsible for the regulation of the implantation window and the current study hypothesised that their receptors may be implicated in women undergoing oocyte donation. Implantation is directly dependent on the synchronization of the fertilized egg’s progression into a blastocyst and the specific differentiation of the endometrium through molecular and cellular changes regulated by agents with an endocrine, paracrine or autocrine activity. Study design, size, duration The study was conducted at the 1st Dept. of OB-GYN, Centre for Human Reproduction of the Aristotle University of Thessaloniki, ‘Papageorgiou’ General Hospital and the ‘Biogenesis’ Assisted Reproduction Centre, (both in Thessaloniki, Greece). Participants/materials, setting, methods The participants recruited for this prospective study included 15 oocyte donors (age range, 25–32 years; mean age, 28.9±2.89) undergoing IVF treatment. The inclusion criteria were white race, no uterine-ovarian pathology, age &amp;lt;35 years and no prior known medical pathology. All donors had undergone extensive preoperative work-up, which included common blood tests, karyotyping, specific test for cystic fibrosis and pap smear. All donors were non-smokers and had given their informed consent. Main results and the role of chance Both ERα and PR-B were expressed abundantly on both days (0 and 5; Fig. 1B). The ERα nodal staining percentage on day 0 was age-related, with patients aged &amp;lt;30 years showing 100% staining and those aged &amp;gt;30 years showing 90% staining (Mann-Whitney U test; P = 0.014; Fig. 2A)Both steroid hormone receptors showed significant variation between days 0 and 5, both in the nodal and stromal preparations. According to Wilcoxon signed-rank test; for ER (nodes% and stromal%) Day 0/5, P = 0.0001; for PR (nodes% and stromal%) Day 0/5, P = 0.0001 and P = 0.035, respectively; for ER (Grade nodes and stromal) Day 0/5, P = 0.0001; and for PR (Grade nodes and stromal) Day 0/5, P = 0.0001 and P = 0.016, respectively (Fig. 2B and ​andC;C; Table I). Limitations, reasons for caution Immunohistochemistry is less quantitative than western blotting. Alternatively, ELISA or a gene expression assessment of both receptors using RT-qPCR could have been conducted. However, due to ethical restrictions, sufficient tissue for protein extraction could not be obtained in order to pursue this further. Wider implications of the findings: It was shown herein that both ER-a and PR-B were expressed abundantly on days 0 and 5, showing significant variation in the nodal and stromal preparations. Age appeared to be a critical factor, since ER-a nodal staining showed higher values in the age group of oocyte donors &amp;lt;30 years old. Trial registration number 15

Unraveling the origin of aged varnishes for the proper restoration of old paintings using spectroscopic and spectrometric techniques

This study deals with the investigation of old varnishes from six paintings belonging to the collection of the “Teloglion Foundation of Arts”, Aristotle University of Thessaloniki in Greece employing three complementary analytical techniques. The purpose of this research was to identify the origin of the protective layers of the varnishes with the ultimate goal of their safe removal during their treatment. To identify the components of the varnishes, sampling was carried out in both a mechanical and chemical way from selected areas of all the works of art. The samples were firstly studied with Fourier-Transform Infrared Spectroscopy (FT-IR), secondly with Pyrolysis-Gas Chromatography/Mass Spectrometry (Py-GC–MS), and finally with Liquid Chromatography–Orbitrap High-Resolution Mass Spectrometry (LC–Orbitrap HRMS). The application of these methods led not only to the verification of the compounds of the varnishes, but also to the presence of specific fatty acids included in the drying oils, as well as diterpene and triterpene resins. FT-IR spectra were very similar to those corresponding to natural resins, while Py-GC–MS evidenced the fatty acids profile in drying oils as well as the presence of dammarane skeleton among others. The main findings from LC–Orbitrap MS/MS included drying and essential oils, mastic, and dammar. Based on the obtained results, a solubility study of varnishes was also performed. The appropriate mixture of solvents for the coating varnishes removal was investigated with the aid of the Teas solubility triangle and the most suitable solvent mixture for the proper restoration was proposed. A conservation effort for one painting was carried out successfully, confirming the applicability of the method.

University students’ perception of the factors affecting preschool and primary students’ recycling behaviour as a tool to improve environmental education in the university curriculum (Percepción de los estudiantes universitarios de los factores que influyen sobre la conducta de reciclaje de los estudiantes de educación infantil y primaria como herramienta para mejorar la educación ambiental en el currículum universitario)

ABSTRACT The purpose of this synthetic work is to examine university students’ perception of children’s relevant factors for recycling behaviour aiming to improve their university curriculum. The main idea of this analysis was to focus on faculty of education students, as they will be the future environmental educators that will provide the basic environmental knowledge to students in preschool and primary education. A systematic review was performed to reveal potential factors influencing the recycling behaviour of children, and then a new survey was conducted through a questionnaire to evaluate the 320 university students’ perception of the Faculty of Education of Aristotle University of Thessaloniki on the factors affecting the preschool and primary school students towards recycling. The findings indicated that university students’ perception is in line with the bibliography and show that according to students, the family environment is the most important factor affecting children’s recycling behaviour.

Jet or conventional local anaesthesia? A randomized controlled split mouth study.

To compare the efficacy, acceptance and preference of conventional infiltration technique with a needleless jet anaesthetic device (Comfort-In). Non-fearful healthy adult volunteers, aged 19-40 years, were recruited in the Dental School of Aristotle University of Thessaloniki, Greece. Intact maxillary premolars were selected for local anaesthesia. Both techniques were applied sequentially with 35 min time gap on either buccal side on the same day by the same operator. The quadrant and the order of administration were randomly assigned using an online randomization generator. Immediately after administration, at 1, 3, 5, 10, 15, 20, 25 and 30 min, pulp vitality and soft tissue pain reaction tests were performed. Each participant was asked 6 questions in order to assess acceptance. At the end of the session, at 24 h and 7 days, all participants were asked to report any adverse events and their preference. In 63 volunteers who were successfully followed, 63 teeth received conventional local infiltration and 63 the Comfort-In. Both techniques presented with similar anaesthetic efficacy at 1, 3, 5, 10 and 15 min, whereas the conventional technique was more efficacious at 20 min (p < 0.005). Both presented similar acceptance apart from higher pain/discomfort during administration of Comfort-In (p = 0.002). Significantly higher preference was reported for the conventional technique immediately after the session, at 24 h and at 7 days (p < 0.0005); 19 (30.2%) reported the presence of ecchymosis or lacerations at the Comfort-In site as opposed to 5 (7.9%) with the conventional method (p < 0.0001). Both techniques showed similar effectiveness. Conventional infiltration was preferred to needleless anaesthesia by non-fearful adult volunteers and was associated with less adverse events. This study enhances the advantages of conventional local anaesthesia. ISRCTN17400733.

Use of reference management software among postgraduate students in Greece

The use of reference management software in the context of academic work and research is the main subject of this study. The study focuses on the extent to which postgraduate students at the Aristotle University of Thessaloniki, one of the largest Greek universities, make use of – or avoid using – reference management software tools to organize their bibliographic databases and to automate the process of creating references and citations. The study also tries to find out which are the key factors for their choices and whether certain background characteristics affect their behavior. It should be mentioned that no previous studies have been conducted in Greece regarding the use of reference management software in the academic environment. An online questionnaire was sent to the postgraduate students at the University and a result set of 545 responses was collected and analyzed. The majority (almost two-thirds) of the respondents identified themselves as non-users and one-third identified themselves as reference management software users. Among the latter, Mendeley was found to be the software used by more than two-thirds of the users and was followed by EndNote and Zotero. It is worth mentioning that Mendeley is the software officially recommended by the University’s central library to its users but most of the students (more than 60%) were not aware of this fact. In terms of background characteristics, the analysis revealed, among other things, statistically significant relationships between degree level, student discipline and preferences, reference management software features, and potential future use of reference management software.

Crossing Swords while Crossing Boundaries: Teaching Translation through Intermedial Translation Slams

This paper discusses a cross-curricular translation project conducted within the framework of the literary translation and interlingual audiovisual translation (undergraduate) courses taught at the School of English, Aristotle University of Thessaloniki. The project was part of an optional module on literary translation and subtitling where students had to translate and subtitle into Greek some extracts of Margaret Atwood’s The Handmaid’s Tale and the relevant screenplay. The present paper thus explores the outcome of an online intermedial translation slam, a ‘duel,’ between student-translators and student-subtitlers, who were asked to look at translation through another lens. Slamming is, thereby, viewed as a tool that can enhance the skills of literary translation and subtitling students, inviting them to participate in a thought-provoking process sharing and apposing insights, comparing and juxtaposing ideas, while being involved in an exchange of meaning and understanding. How does the interrelationship between different modes and media affect the choices literary translators and subtitlers make? What happens when a novel migrates into another language twice within the discursive spaces of intermedial dialogue? What are the benefits of engaging students in collaborative work and exposing them to simulated/real-life tasks? These are some of the questions that the paper will address and attempt to answer. The overarching goal is to examine the potential and advantages of integrating translation slams in a project-based approach to teaching and training literary translators and subtitlers within an academic framework.

Benjamin Constant E.J.B. Hendrickx

Benjamin Constant E.J.B. Hendrickx William Henderson Click for larger view View full resolution BENJAMIN CONSTANT E.J.B. HENDRICKX (25/7/1939 – 8/7/2021) [End Page 1] It was with great shock and deep sadness that academics here and abroad received the news of the passing of Benjamin (Ben) Hendrickx. His wide circle of colleagues, students, and friends in the three main areas of his interest and influence, Belgium, Greece, and Africa, mourn his death, but also celebrate his life as international scholar, inspiring teacher, and devoted family man. Ben was born on 24 July 1939 in Deurne, a suburb of Antwerp. He received his early schooling at St. Stanislas College in Berchem, matriculating in Greek, Latin, and the Studia humaniora. Annual scholarships from the Belgian State enabled him to pursue his studies at the University of Louvain-Leuven from 1958 to 1962. In 1960 he was awarded the Candidature ès Philosophie et Lettres, Section: Ancient History, in 1962 the Licence ès Philosophie et Lettres, Section: Ancient History cum laude, with a dissertation on Het Kroningsceremonieel in Byzantium: Onderzoek naar de Oorsprong der Kroningselementen in de Teksten van Suetonius en de Scriptores Historiae Augustae, written under the supervision of Professor J. Vergote, and the Agrégation ès Philo-sophie et Lettres, also cum laude. While still at university Ben had met Thekla Sansaridou, from Thessaloniki. They had corresponded since 1958, in English, the only language they shared. Two years later, when Ben and a friend visited Greece, they finally met in person on 3 September 1960, at the Thessaloniki railway station. Two weeks later, before Ben's return to Belgium, they got engaged. Thekla and her mother visited the Hendrickx family that Christmas and New Year. The following year, on 31 December 1961, they were married in Thessaloniki and in January 1962 they settled in Antwerp where Ben continued his studies. Ben's first appointment, in 1962, was as a high school teacher at St. Ludargis School in Antwerp. He continued with his studies at Louvain: Philologie orientale chrétienne (1963-1964) and the Licence ès Histoire et Civilization byzantines (1964), with a dissertation titled Poging tot Reconstructie [End Page 2] van de Kroningsceremonie van de Keizer in de laat Byzantijnse Tijd, again with Vergote as supervisor. His next appointment, from 1964 to 1969, was as a lecturer at the Collèges Lamennais, Javouhey and Pomaré, in Tahiti. Here he began work on his doctorate, but also studied for and obtained the Diplômes de morpho- et graphopsychologie at the Institut de Culture Humaine in Paris (1967-1968). The couple returned to Greece in 1969 when Ben received scholarships from the Greek State to complete his PhD at the Aristotle University of Thessaloniki. In 1970 he was awarded the degree Doctor Philosophiae for his dissertation titled Οι πολιτικοί και στρατιωτικοί θεσμοί της Λατινικής Αυτοκρατ-ορίας Κωνσταντινουπόλεως κατά τους πρώτους Χρόνους της Υπάρξέως της (The Political and Military Institutions of the Latin Empire of Constantinople during the First Years of its Existence), written under the supervision of Professor Ioannes Karayiannopoulos. This work was published as a book in 1970 and reprinted in 1999. He continued research at the university until 1971, when his career and their lives took a decisive turn. In June, when they were preparing to move to Belgium, Professor Paul du Plessis, who with his wife Yvonne had travelled by bus from Athens, arrived in Thessaloniki to meet Ben, and persuaded them to delay their departure. Professor Du Plessis could not explain how he had obtained Ben's address and information about his qualifications, but he wanted to have Ben working with him at the University of Port Elizabeth (now the Nelson Mandela University). However, he failed to persuade the Rector of that university to appoint Ben and instead turned to the Rector of the Rand Afrikaans University (RAU, now the University of Johannesburg, UJ), Professor Gerrit Viljoen, who offered Ben a signed contract as Senior Lecturer in the Department of Classics. Ben, Thekla, and their children Annoula, Raita, and Yannis arrived in South Africa in 1971. Assigned to meet them at the airport, I had to wait a while for them to emerge. There had been a hitch at immigration when Ben's passport gave his surname as Hendrickx, whereas Thekla...

An overview of the ATLAS New Small Wheel Micromegas construction project at Aristotle University

The upcoming luminosity upgrade of the LHC will impose new requirements for the detector installations. To perform under these conditions the Micromegas (MM) technology was selected to be adopted in the New Small Wheel (NSW) upgrade, dedicated to precision tracking. A large surface of the forward regions of the Muon Spectrometer will be equipped with 8 layers of MM modules forming a total active area of 1200 m2. The NSW is planned to be installed in the forward region of [Formula: see text] of ATLAS. This new system will have to operate in a high background radiation region, while reconstructing muon tracks as well as furnishing information for the Level-1 trigger. The project requires fully efficient MM chambers with spatial resolution down to 100 [Formula: see text]m, a rate capability up to about 15 kHz/cm2 and operation in a moderate (highly inhomogeneous) magnetic field up to [Formula: see text][Formula: see text]T. The required tracking is linked to the intrinsic spatial resolution in combination with the demanding mechanical accuracy. An overview of the design, construction and QA/QC procedures followed at the Aristotle University of Thessaloniki for the Micromegas LM2 Drift panels production will be presented.

Development of a reliable preoperative risk stratification system for phacoemulsification.

To present a statistically validated risk classification system for intraoperative complications in cataract surgery. 2nd Department of Ophthalmology, Aristotle University of Thessaloniki, Thessaloniki, Greece. Prospective observational study. All patients underwent phacoemulsification surgery by experienced, high-volume surgeons for cases with intraoperative complications. The presence of several risk factors was statistically assessed with the help of multiple correspondence analysis to determine the more reliable rank categorization for severity and to calculate a total risk score. This study included 1572 consecutive patients. The proposed system had 3 risk groups and a no-risk group and had high statistical reliability. A comparison of this system against a previously asserted empirical system showed higher internal reliability. Previous efforts to construct a risk classification system for intraoperative complications in cataract surgery have been empirically defined and tested against practice-as-usual. The system in this study quantified risk more accurately and provided an experienced clinician with a reliable means of assessing the preoperational likelihood of intraoperative complications.

Psychometric properties of dementia attitudes scale, dementia knowledge assessment tool 2 and confidence in dementia scale in a Greek sample.

AimΤo validate the Greek version of the Dementia Knowledge Assessment Tool 2, the Dementia Attitudes Scale and Confidence in Dementia Scale.DesignA quantitative cross‐sectional design was applied for translation and validation. The STROBE checklist for observational research has been followed to this survey.MethodTwo hundred and twelve students from the School of Psychology (Aristotle University of Thessaloniki). Psychometric properties were assessed through construct validity (principal component analysis), internal consistency (Cronbach's alpha) and convergent validity.ResultsHigh internal reliability was found for Confidence in Dementia Scale (α = 0.85), adequate reliability for Dementia Attitudes Scale (α = 0.74) and acceptable reliability for Dementia Knowledge Assessment Tool 2 (α = 0.68).

Yielding Morphological Characteristics and Biochemical Analysis of “Karma lemon” Cannabis Producing Cannabinoids in Thessaloniki-Greece

Cannabis has been widely used by humans over many centuries as a source of fiber, oil and for medicinal purposes. Its use was illicit in numerous countries, including Greece and Lebanon. &amp;ldquo;Karma Lemon&amp;rdquo;, one of the newest cannabis strain originated from Italy, is selected in this study to analyze its components using various techniques starting from the extraction, isolation and identification of cannabinoids using separatory compounds and NMR techniques as well as the main important morphological traits of this strain to be harvested at an appropriate time for medicinal uses in Greece and later on, in Lebanon. Thirty different samples were selected from the field of respected &amp;ldquo;Hemp Way Company&amp;rdquo; in Thessaloniki and studied for morphological traits. These were related to the length of the plant at harvest time (1.809 m) needed for the use of combines and the weight of inflorescence (213.5 g fresh and 40.8 g dry) for oil or seed production. Three samples of Karma Lemon cannabis strain inflorescence were analyzed at the Laboratory of Pharmacognosy, School of Pharmacy, in the Aristotle University of Thessaloniki in Greece, after proper extraction and isolation using ethanol and other separation compounds. TLC and NMR techniques were used to visualize and identify cannabinoids present after isolation. Cannabinoid acids, CBG, CBN, THC, CBD and other cannabinoids were identified and isolated.
