Biochemical Dysregulation of Pre-Eclampsia and Gestational Diabetes Mellitus

Emerging evidence indicates that among the various pregnancy complications, pre-eclampsia and gestational diabetes mellitus (GDM) seem to have, at least in part, shared underlying ethiologies. Apart from sharing numerous risk factors, it has been shown that the rate of pre-eclampsia is influenced by the presence and severity of GDM, with hyperglycemia due to insulin resistance and the biochemical changes this brings about (angiogenic imbalance, oxidative stress and inflammation), playing some role in the pathogenesis of endothelial dysfunction leading to the development of pre-eclampsia. However, so far the biochemical mechanisms underlying and linking these two conditions is still not properly understood. The altered physiological parameters, dysregulation of potential protein biomarkers and DNA-related changes (mutations, methylations, miRNAs) will be combined in this review to explore possible underlying mechanisms

Mental health and wellbeing promotion and support : education leaders’ perceptions and experiences

Educator leaders play a vital role in fostering educators’ and students’ mental health and wellbeing. Through qualitative research, this paper provides insights from eight education leaders working in State Schools in Malta on their perceptions of, and experiences in, the promotion and support of mental health and wellbeing among educators and students. The objective of the study is to examine how mental health and wellbeing are being promoted, addressed, and supported in schools. Eight semi-structured interviews were conducted with education leaders followed by a reflexive thematic analysis. Four themes emerged from the data, namely school philosophy, ethos, and leadership; mental health and wellbeing in schools; loss and grief; and Covid-19 and its impact on mental health and wellbeing in schools The findings suggest the need for more proactive and supportive considerations of mental health and wellbeing in schools in Malta, along with the implementation and evaluation of mental health and wellbeing whole-school projects in schools.peer-reviewe

Flexible Virtual Reality System for Neurorehabilitation and Quality of Life Improvement

As life expectancy is mostly increasing, the incidence of many neurological disorders is also constantly growing. For improving the physical functions affected by a neurological disorder, rehabilitation procedures are mandatory, and they must be performed regularly. Unfortunately, neurorehabilitation procedures have disadvantages in terms of costs, accessibility and a lack of therapists. This paper presents Immersive Neurorehabilitation Exercises Using Virtual Reality (INREX-VR), our innovative immersive neurorehabilitation system using virtual reality. The system is based on a thorough research methodology and is able to capture real-time user movements and evaluate joint mobility for both upper and lower limbs, record training sessions and save electromyography data. The use of the first-person perspective increases immersion, and the joint range of motion is calculated with the help of both the HTC Vive system and inverse kinematics principles applied on skeleton rigs. Tutorial exercises are demonstrated by a virtual therapist, as they were recorded with real-life physicians, and sessions can be monitored and configured through tele-medicine. Complex movements are practiced in gamified settings, encouraging self-improvement and competition. Finally, we proposed a training plan and preliminary tests which show promising results in terms of accuracy and user feedback. As future developments, we plan to improve the system's accuracy and investigate a wireless alternative based on neural networks.Comment: 47 pages, 20 figures, 17 tables (including annexes), part of the MDPI Sesnsors "Special Issue Smart Sensors and Measurements Methods for Quality of Life and Ambient Assisted Living

New Mediterranean biodiversity records (October 2015)

The Collective Article “New Mediterranean Biodiversity Records” of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article has adopted a country-based classification and the countries are listed according to their geographic position, from west to east. New biodiversity data are reported for 7 different countries, although one species reported from Malta is new for the entire Mediterranean basin, and is presumably also present in Israel and Lebanon (see below, under Malta). Italy: the rare native fish Gobius kolombatovici is first reported from the Ionian Sea, whilst the alien jellyfish Rhopilema nomadica and the alien fish Oplegnathus fasciatus are first reported from the entire country. The presence of O. fasciatus from Trieste is concomitantly the first for the entire Adriatic Sea. Finally, the alien bivalve Arcuatula senhousia is reported for the first time from Campania (Tyrrhenian Sea). Tunisia: a bloom of the alien crab ortunus segnis is first reported from the Gulf of Gabes, where it was considered as casual. Malta: the alien flatworm Maritigrella fuscopunctata is recorded in the Mediterranean Sea for the first time, on the basis of 25 specimens. At the same time, web searches include possible unpublished records from Israel and Lebanon. The alien crab P. segnis, already mentioned above, is first formally reported from Malta based on specimens collected in 1972. Concomitantly, the presence of Callinectes sapidus in Maltese waters is excluded since based on misidentifications. Greece: the Atlantic northern brown shrimp Penaeus atzecus, previously known from the Ionian Sea from sporadic records only, is now well established in Greek and international Ionian waters. The alien sea urchin Diadema setosum is reported for the second time from Greece, and its first record from the country is backdated to 2010 in Rhodes Island. The alien lionfish Pterois miles is first reported from Greece and concomitantly from the entire Aegean Sea. Turkey: the alien rhodophyte Antithamnion hubbsii is first reported from Turkey and the entire eastern Mediterranean. New distribution data are also provided for the native fishes Alectis alexandrina and Heptranchias perlo. In particular, the former record consists of a juvenile measuring 21.38 mm total length, whilst the latter by a mature male. Cyprus: the rare native cephalopod Macrotritopus defilippi, and the alien crab Atergatis roseus, sea slug Plocamopherus ocellatus and fish Cheilodipterus novemstriatus are first recorded from the entire country. Lebanon: the alien crabs Actaea savignii and Matuta victor, as well as the alien fish Synanceia verrucosa, are first recorded from the entire country. In addition, the first Mediterranean record of A. savignii is backdated to 2006, whilst the high number of M. victor specimens observed in Lebanon suggest its establishment in the Basin. The Atlantic fishes Paranthias furcifer and Seriola fasciata, and the circumtropical Rachycentron canadum, are also first reported from the country. The P. furcifer record backdates its presence in the Mediterranean to 2007, whilst S. fasciata records backdate its presence in the eastern Mediterranean to 2005. Finally, two of these latter species have been recently ascribed to alien species, but all three species may fit the cryptogenic category, if not a new one, better.peer-reviewe

The rise of Public History: an international perspective

This article explores the birth and development of public history and presents the different criteria of its internationalization from the 1970s to the more recent creation of the International Federation of Public History. Based mostly on North America and Europe, the international perspective sets the development of public history in the United States into a broader context of debates about the changing role of historians. While public history was mostly perceived in the 1980s as the application – through consulting – of history to present- day issues, the more recent internationalization is made of a variety of local and national approaches to the field

Epithelial Interleukin‐1 Receptor‐Like‐1 Activation Is Contingent on Interleukin‐33 Isoforms and Asthma‐Related Receptor Variation

IntroductionThe interleukin-33/interleukin-1 receptor-like-1 (IL-33/IL1RL1) signalling pathway is implicated in asthma pathogenesis, with IL1RL1 nonsynonymous genetic polymorphisms associated with disease risk. We aimed to determine these variants' effect on IL1RL1 signalling induced by different IL33 isoforms thought to be elevated in the asthmatic airway.MethodIn a project funded by GSK plc, which has developed an IL-33 receptor inhibitor for asthma treatment, human embryonic kidney 293 (HEK293) cells expressing secreted embryonic alkaline phosphatase (SEAP) driven by a nuclear factor kappa-beta (NF-κB) promoter, were transiently transfected with IL1RL1, containing one of four extracellular and Toll/interleukin 1 receptor (TIR) domain haplotypes. Cells were stimulated with seven different splice and proteolytic-generated IL-33 isoforms (0.001–50 ng/mL) for 24 h. Supernatant SEAP activity and interleukin-8 (IL-8) levels were determined. Primary human bronchial epithelial cells (HBECs) representing different genotype carriers were stimulated with IL-33112–270 (50 ng/mL) and induced IL-8 mRNA expression measured.ResultsHEK293 cells carrying both asthma extracellular and TIR domain IL1RL1 risk haplotypes presented maximal IL33-driven signalling, with minimal signalling after IL-33 activation in other protective haplotypes. All IL-33 isoforms activated IL1RL1 but with differing magnitudes. Proteolytically cleaved IL3395–270 and IL33106–270 had the greatest effect and the IL33113–270, and Exon 3,4 deletion isoform exhibited the lowest. The effect of extracellular and TIR domain genetic variants on receptor signalling was replicated in primary HBECs. Maximal IL1RL1 signalling was observed in cells carrying both extracellular and TIR signalling domain risk haplotypes.ConclusionsOverall, our study suggests asthma patients carrying the extracellular and TIR domain risk haplotype and have a lung microenvironment that promotes elevated levels of cleaved IL33, particularly where IL3395–270 and IL33106–270 may be more amenable to IL33/IL1RL1 targeting
