Authors: Moshari-Nasirkandi Atefeh , Alirezalu Abolfazl , Alipour Hadi , Amato Jussara
Published: October 2023

The Lamiaceae family encompasses numerous species highly valued for their applications in medicine, food, and cosmetics. In order to screen the Lamiaceae family and discover new sources of phytochemicals and antioxidants, we comprehensively evaluated 20 species from this family, including Phlomis herba-venti, P. tuberosa, P. olivieri, P. kurdica, Nepeta sp., N. cataria, N. saccharata, Stachys sp., S. inflata, Scutellaria albida, Marrubium parviflora, Mentha pulegium, Thymus kotschyanus, Lamium album, Salvia officinalis, S. multicaulis, S. macrochlamys, S. candidissima, S. verticillata, and S. nemorosa. The aerial parts of these species were analyzed to determine their total phenolic (TPC) and flavonoid (TFC) contents, total tannin content (TTC), ascorbic acid content (AAC), antioxidant capacity (assessed by FRAP and DPPH assays), and polyphenolic components (by HPLC). The phytochemical compounds and antioxidant properties varied widely among different species. The highest concentrations of TPC (70.93 mg GAE/g DW), TFC (17.89 mg Que/g DW), TTC (6.49 mg TAE/100 g), and AAC (1.15 mg AA/g DW), as well as the greatest antioxidant activity, were observed in different Salvia species. Additionally, chlorogenic and rosmarinic acids were the primary phenolic compounds identified in the extracts from the investigated Lamiaceae family. According to Hierarchical Cluster Analysis (HCA) and Principal Component Analysis (PCA), three groups of species were identified, characterized by variations in phytochemical composition and antioxidant capacity. The results obtained can provide new natural sources of phytochemicals and antioxidant agents, particularly from Salvia species, for the advancement of new products in the food, agricultural, cosmetics and health industries.

Published: October 2023

To investigate the effect of endovascular and/or hybrid surgical recanalization on chronic long-segment occlusion of the internal carotid artery (ICA) and the effect of occlusion location on the recanalization rate and prognosis, 87 patients with chronic ICA occlusion treated with endovascular approach only or hybrid surgery were retrospectively enrolled. The duration of ICA occlusion ranged from 21 to 360 days (median 30). Type I occlusion (from the neck to below the cavernous segment) consisted of 46 (52.8%) patients while type II (from the neck to above the clinoid segment) of 41 (47.1%). Hybrid surgery was performed in 44 (50.6%) patients while endovascular recanalization only was conducted in the other 43 (49.4%). In all patients, the success rate of recanalization was 93.0% (40/43) for the endovascular approach and 95.5% for the hybrid surgical approach. In patients with type I occlusion, endovascular recanalization only was performed in 22 (47.8%) patients and hybrid surgery in 24 (52.2%), resulting in successful recanalization in all patients (100%). In patients with type II occlusion, the success rate of recanalization was 85.7% (18/21) for the endovascular approach only but 90% (18/20) for the hybrid surgery. The total success rate of recanalization was 94.3% (82/87) for all patients, 100% for type I occlusion, and 87.8% for type II occlusion. No significant (P = 0.12) differences existed in the recanalization rate between groups I and II. Clinical follow-up was performed in 82 (94.3%) patients 6–39 months (mean 16) after the surgery. Re-occlusion occurred in 0 in group I but in four (9.8%) in group II. The mRS was good with 0–2 in 38 (82.6%) patients in group I and in 27 (75%) patients in group II, with no significant (P = 0.78) difference. In conclusion, chronic long-segment ICA occlusion can be safely and efficiently recanalized with the endovascular and hybrid surgery. The location of ICA occlusion may have a critical role in determining the recanalization rate, and careful evaluation of the occlusion location may be helpful in increasing the prognosis of recanalization.
Task-based activation and resting-state connectivity predict individual differences in semantic capacity for complex semantic knowledge
Authors: Rabini Giuseppe , Ubaldi Silvia , Fairhall Scott L.
Published: October 2023

Our ability to know and access complex factual information has far reaching effects, influencing our scholastic, professional and social lives. Here we employ functional MRI to assess the relationship between individual differences in semantic aptitude in the task-based activation and resting-state functional connectivity. Using psychometric and behavioural measures, we quantified the semantic and executive aptitude of individuals and had them perform a general-knowledge semantic-retrieval task (N = 41) and recorded resting-state data (N = 43). During the semantic-retrieval task, participants accessed general-knowledge facts drawn from four different knowledge-domains (people, places, objects and ‘scholastic’). Individuals with greater executive capacity more strongly recruit anterior sections of prefrontal cortex (PFC) and the precuneus, and individuals with lower semantic capacity more strongly activate a posterior section of the dorsomedial PFC (dmPFC). The role of these regions in semantic processing was validated by analysis of independent resting-state data, where increased connectivity between a left anterior PFC and the precuneus predict higher semantic aptitude, and increased connectivity between left anterior PFC and posterior dmPFC predict lower semantic aptitude. Results suggest that coordination between core semantic regions in the precuneus and anterior prefrontal regions associated with executive processes support greater semantic aptitude.
Anti-site defect-induced disorder in compensated topological magnet MnBi2-xSbxTe4
Authors: Lüpke Felix , Kolmer Marek , Yan Jiaqiang , Chang Hao , Vilmercati Paolo , Weitering Hanno H. , Ko Wonhee , Li An-Ping
Published: October 2023

The gapped Dirac-like surface states of compensated magnetic topological insulator MnBi2-xSbxTe4 (MBST) are a promising host for exotic quantum phenomena such as the quantum anomalous Hall effect and axion insulating state. However, it has become clear that atomic defects undermine the stabilization of such quantum phases as they lead to spatial variations in the surface state gap and doping levels. The large number of possible defect configurations in MBST make studying the influence of individual defects virtually impossible. Here, we present a statistical analysis of the nanoscale effect of defects in MBST with x=0.64, by scanning tunnelling microscopy/spectroscopy. We identify (Bi,Sb)Mn anti-site defects to be the main source of the observed doping fluctuations, leading towards the formation of nanoscale charge puddles and effectively closing the transport gap. Our findings will guide further optimization of this material system via defect engineering, to enable exploitation of its promising properties.
Digital twins: a stepping stone to achieve ocean sustainability?
Authors: Tzachor Asaf , Hendel Ofir , Richards Catherine E.
Published: October 2023

Digital twins, a nascent yet potent computer technology, can substantially advance sustainable ocean management by mitigating overfishing and habitat degradation, modeling, and preventing marine pollution and supporting climate adaptation by safely assessing marine geoengineering alternatives. Concomitantly, digital twins may facilitate multi-party marine spatial planning. However, the potential of this emerging technology for such purposes is underexplored and yet to be realized, with just one notable project entitled European Digital Twins of the Ocean. Here, we consider the promise of digital twins for ocean sustainability across four thematic areas. We further emphasize implementation barriers, namely, data availability and quality, compatibility, and cost. Regarding oceanic data availability, we note the issues of spatial coverage, depth coverage, temporal resolution, and limited data sharing, underpinned, among other factors, by insufficient knowledge of marine processes. Inspired by the prospects of digital twins, and informed by impending difficulties, we propose to improve the availability and quality of data about the oceans, to take measures to ensure data standardization, and to prioritize implementation in areas of high conservation value by following the ‘nested enterprise’ approach.

Authors: Madyira Daniel M. , Olatunji Kehinde O.
Published: October 2023

This study examined the possibilities of enhancing methane yield from anaerobic digestion of Xyris capensis and duck wastes based on improved feeding composition and the C/N ratio. Batch anaerobic digestion of Xyris capensis and duck wastes was conducted at mesophilic temperature (37 ± 2 °C) with the mixing ratios of 100:0, 75:25, 50:50, 25:75, and 0:100% of duck wastes: Xyris capensis. The highest methane yield of 301.17 mL CH4/ gVSadded was recorded when the mixing ratio of 50:50% (duck wastes: Xyris capensis) and C/N ratio of 19.26 was digested. The biodegradability (BD) of duck wastes and Xyris capensis were 86.60 and 58.57%, respectively. The BD of duck wastes increases with the addition of Xyris capensis, and it started to decline after a 50:50% mixing ratio. A stronger synergistic influence of co-digestion was noticed compared to monodigestion of the individual of each feedstock. This study showed a better performance of anaerobic co-digestion and can be used to enhance feeding composition and the C/N ratio. In general, methane production from duck wastes co-digested with Xyris capensis is a good strategy to generate renewable energy and minimize waste management challenges.

Authors: Olatunji Kehinde O. , Madyira Daniel M.
Published: October 2023

This study investigated the application of Response Surface Methodology (RSM) for optimizing and predicting methane yield from oxidative pretreated Xyris capensis. Input process parameters of retention time, temperature, and pretreatment condition were considered, with methane yield as the response. The results show that all three process parameters selected significantly influence methane yield, and analysis of variance (ANOVA) indicates that the RSM model is significant for the study. A correlation coefficient (R2) of 0.9071 was recorded, which implies that the model has 91% prediction accuracy. Interactive influence of temperature and retention time, pretreatment and retention time, and pretreatment and temperature were significant to methane release. Optimum conditions for methane release from RSM model are 14 days retention time, 25 °C temperature, and pretreatment condition of 85% H2O2 and 15% H2SO4 with daily optimum methane yield of 32.65 mLCH4 /gVSadded. This study shows that RSM is suitable for methane yield optimization and prediction during the anaerobic digestion of oxidative pretreated lignocellulose substrates.

Published: October 2023

Entering the 21st century, building energy consumption ranks first in total energy consumption, environmental pollution is increasing, and the construction sector has become the main energy source. The ability to reduce greenhouse gas emissions by replacing fossil fuels such as oil, gas and coal with fuels from renewable sources is a key factor in the development of net zero energy buildings. Therefore, it is important to analyze and organize previous and current research in this area to get an overview of the importance of built environmental assessment and net zero energy buildings. This review therefore summarizes the literature of previous life cycle assessment (LCA) and energy modeling studies conducted for environmental assessment of construction and construction-related industry sectors, considering construction products and entire building systems, buildings and civil structures. Bibliographic methods and scientometric analyzes have been adopted and proposed to tentatively explore research themes in this field. This observation indicates that BIM-LCA (Building Information Management Life Cycle Assessment) optimization is currently an important and inevitable research focus in the building-related energy field. Finally, there was a qualitative discussion on the achievement of key goals. We provided an up-to-date literature review on LCA construction, used energy system models to assess environmental impacts, and discussed key challenges in LCA construction, ongoing research, and possible solutions to solve the identified problems. The results also provide a comprehensive knowledge framework linking previous and current research areas with future research trends. The results provide researchers with an interdisciplinary focus on insights and solid engineering knowledge from the latest research on BIM-LCA.

From Targets to Action: Analyzing the Viability of REPowerEU in Achieving Energy Sustainability
Authors: Dolge Kristiāna , Blumberga Dagnija
Published: October 2023

EU’s energy sector is facing turbulent times as it strives to strengthen energy independence without losing sight of providing affordable and sustainable energy to all. The European Commission’s REPowerEU plan to accelerate the EU’s energy transition places additional pressure on each member state’s path to energy sustainability. To reach this objective, policymakers must assess the present energy sustainability levels of each member state, identify areas for development, and monitor the county’s progress over time. The purpose of this article is to analyze and compare the energy sustainability levels of the EU member states using a variety of indicators and to identify key cornerstones for advancing their energy transition. This study develops an energy sustainability composite index (ESCI) in order to unravel and compare the multiple lawyers of energy sustainability, including energy security, primary energy intensity, share of renewable energy resources, energy efficiency, CO2 emission intensity, and energy poverty. Log-Mean Divisia Index (LMDI) decomposition analysis is utilized to track the progress of energy policy in achieving reductions in energy-related CO2 emissions from 2015 to 2019. Changes in CO2 emissions were decomposed using Kaya identity factors to determine which of the following factors contributed the most to the changes: changes in emission intensity, energy intensity, economic or population growth. The results indicate that all EU member states have untapped potential for improving energy sustainability.

Authors: Akutsu-Suyama Kazuhiro , Ueda Misaki , Shibayama Mitsuhiro , Ishii Kosuke , Nishi Naoya
Published: October 2023

In neutron scattering studies, deuterium-labelled compounds play a key role in controlling the contrast of organic samples and reducing the incoherent scattering background from the samples. As amine compounds play a vital role as functional molecules, we have developed a new synthesis method using an amide compound as a starting material to synthesize deuterated amines and their analogues. We determined the deuteration ratio of the obtained deuterated 1-octylamine by mass spectrometry, nuclear magnetic resonance (NMR), and neutron reflectometry techniques. As a result, the deuteration ratio was estimated to be ~60 %. The deuteration ratio of the synthesized 1-octylamine was not high because the method used did not deuterate its α-protons and NH2 group. However, this synthesis method is suitable for the large-scale synthesis of deuterated amine compounds for neutron research because it is easy to increase the synthetic scale.

Authors: Mikula Pavol , Ryukhtin Vasyl , Strunz Pavel , Džugan Jan
Published: October 2023

Feasibility of focusing high-resolution three-axis diffractometer with the polycrystalline sample between the monochromator and the analyzer was tested for studies of finer effects of powder diffraction lines and for investigations of special tasks of powder diffractometry. The focusing 3-axis diffractometer set-up equipped with bent perfect crystal monochromator and analyzer offers the sensitivity in determination e.g. of strains in polycrystalline materials ε =Δd/d close to 10-5. Together with special tasks of strain/stress studies related namely, to plastic deformation, it permits to study a finer substructure of individual diffraction lines which can appear e.g. in case of polycrystalline alloys where more phases having very close values of the lattice spacing could exist. Resolution properties of the high-resolution diffractometer setting will be documented on several experimental results obtained on unconventional bulk samples.
Imagerie du foie et des voies biliaires
Authors: Colombe Philippe , Hahn Harriet
Published: October 2023

Les examens d’imagerie font partie intégrante de la prise en charge diagnostique d’une hépatopathie. L’échographie est, à ce jour, l’examen le plus accessible et le plus indiqué en première intention afin d’évaluer des anomalies diffuses ou focales du parenchyme hépatique ainsi que des voies biliaires. La sensibilité de cet examen peut se révéler très bonne pour un vétérinaire expérimenté, en fonction des affections. Toutefois la limite majeure de cet examen réside dans son manque de spécificité à distinguer les différentes affections entre elles. Il reste donc nécessaire de réaliser des prélèvements lors d’anomalie aspécifique visualisée, tout comme en l’absence d’anomalie échographique dans un contexte clinique et/ou biologique évocateur d’une pathologie hépato-biliaire. L’examen radiographique apporte un intérêt limité dans l’évaluation de cet organe. À l’inverse, le scanner est particulièrement indiqué pour les chiens de grande taille, en planification préopératoire de masse hépatique ou lors de suspicion d’anomalie vasculaire.
Prise en charge d’une lipidose hépatique : traitements médical et nutritionnel
Authors: Mantelli Morgane
Published: October 2023

La lipidose hépatique est une affection cholestatique commune, mais potentiellement fatale chez le chat. Les chats en surpoids sont prédisposés. Dans la majorité des cas (>95 %), la lipidose est secondaire et les chats présentent une affection concomitante à l’origine d’un état hyper-catabolique. Le traitement de la cause sous-jacente est donc nécessaire. Pour autant, un traitement spécifique à la lipidose doit être instauré dès que le chat est hospitalisé. Un soutien nutritionnel précoce par une alimentation assistée par voie entérale est indispensable. La réalimentation précoce est le point-clé du traitement. L’usage de sondes de réalimentation est nécessaire. L’aliment idéal a une teneur en protéines élevée, une teneur modérée en lipides et est pauvre en glucides. La restriction protéique n’est pas requise. De plus, un traitement de soutien visant à stabiliser les constantes vitales, corriger la déshydratation et les troubles ioniques est nécessaire. Une supplémentation vitaminique doit être instaurée chez tout chat suspecté de lipidose.

Gegenstand und Ziel Im Artikel werden Lücken und Herausforderungen der Kostenfolgenschätzung zu Kindeswohlgefährdung im SGB VIII und im Gesundheitssektor (SGB V) beschrieben, die für den Gesundheitssektor anhand von Berechnungen zu Daten gesetzlicher Krankenversicherungen illustriert werden.

Material und Methoden Die Berechnungen basieren auf Abrechnungsdaten gesetzlicher Krankenversicherungen aus den Jahren 2010–2021 mit den ICD-10-Diagnosecodes T74.x, Y05, Y06.x, Y07.X, Z61, Z61.2, Z61.4, Z61.5, Z61.6, Z61.7 (ICD-10-GM), die Ereignisse im Kontext von Kindesmisshandlung betreffen.

Ergebnisse Die Berechnung der Ein-Jahres-Prävalenz für Kindesmisshandlung zeigt einen Anstieg seit 2010, der für 2021 in 30038 auf die Bundesbevölkerung hoch gerechneten Fällen gipfelt, woraus sich als Annäherung Kosten 2021 im Umfang von rund 11 Mio. Euro ergeben. Im stationären Bereich jedoch wurde je erfasstem Jahr entweder kein oder höchstens ein Fall von Kindesmisshandlung dokumentiert.

Schlussfolgerungen Bevölkerungsstudien weisen auf Prävalenzwerte durch Kindesmisshandlung in Deutschland im 2-stelligen Prozentbereich hin. Die Kosten von Kindesmisshandlung in Deutschland im Gesundheitssektor werden entsprechend durch mangelnde Erfassung – nicht nur im stationären Bereich – massiv unterschätzt; für den Kontext Kindes- und Jugendhilfe sind aufgrund fehlender Daten validen Berechnungen von Kostenfolgen nicht mal möglich.

Klinische Relevanz Eine Verbesserung oder teils auch Schaffung der strukturellen Grundlagen zur Datenerfassung von Kostenfolgen von Kindesmisshandlung ist dringend notwendig. Schulungen können die Sensibilität von Fachpersonen im Gesundheitssektor für die Wichtigkeit der Dokumentation von Daten zur Kindesmisshandlung sowie deren standardisierte Erfassung steigern.

Hintergrund Seit Jahrzehnten nimmt der psychosoziale Behandlungs- und Interventionsbedarf im hausärztlichen Setting zu. Insbesondere als schwierig empfundene Interaktionsstile sowie tabuisierte psychosoziale Probleme stellen Hausärzte häufig vor Herausforderungen.

Ziel der Arbeit In dieser Arbeit beschreiben wir den inhaltlichen Hintergrund, die Umsetzung und erste Evaluationsschritte zweier sich ergänzender CME-zertifizierter Online-Fortbildungsangebote für Hausärzte sowie Ärzte in Weiterbildung Allgemeinmedizin (ÄiW AM), die diesen Umstand adressieren.

Material und Methoden Während das Skillslab Heidelberg einen besonderen Fokus auf die interaktionellen Stile von Patienten legt, fokussiert das Projekt BASEpro Ulm auf den Umgang mit tabuisierten psychosozialen Problemen. In beiden Projekten wurden vorab online Bedarfsanalysen durchgeführt.

Ergebnisse Die Online-Bedarfsanalyse des Standorts Heidelberg (N = 54) zeigte den Wunsch nach einem verbesserten Störungswissen und Kommunikationstechniken auf. Die Online-Bedarfsanalyse des Standorts Ulm (qualitative Interviews N = 15; quantitative Befragung N = 117) ergaben insbesondere Unterstützungsbedarf bei der Identifikation tabuisierter psychosozialer Probleme und konkreten Handlungskompetenzen. Die Rückmeldungen zu den beiden Online-Fortbildungen (N = 60 und N = 200) fielen positiv aus. Die Abschlussevaluationen und Wirksamkeitsuntersuchungen werden derzeit vorgenommen.

Diskussion Die praktischen Erfahrungen und Rückmeldungen der beiden Online-Fortbildungen zeigen das Potenzial für die medizinische Fort- und Weiterbildung auf. Da in den bestehenden Online-Fortbildungen nur ausgewählte Themen und Problemlagen aufgegriffen werden konnten, werden inhaltliche Ausweitungen angestrebt. Anmeldungen sind weiterhin kostenlos möglich.

Single-walled carbon nanotubes (SWCNTs) were functionalized by treatment with imino esters through 1,3-dipolar cycloaddition activated by thermal 1,2-prototropy. The reaction was optimized and analyzed by using various heating methods. The functionalization afforded pyrrolidino-functionalized nanotubes that were characterized by using several techniques. The ester group was then transformed into the corresponding SWCNT–iridium carboxylate and, as a proof of concept, the product was tested as a catalyst in the hydrogen-transfer reaction of acetophenone to yield 1-phenylethanol.
Interdental Papilla Regeneration: The Updates on Several Techniques
Authors: Abdul Hayei Nur Ayman , M. Yusof Hazira
Published: October 2023

The procedure for regenerating interdental papilla is complex and technique-sensitive. However, the patient demand to reduce black triangle has dramatically increased in recent years. This article aimed to review the most recent surgical techniques on interdental papilla regeneration by reporting studies published from 2016 to 2021. A literature search was performed in electronic databases, including PubMed, Medline, and Web of Science using the following keywords: “interdental papilla regeneration,” “papillary reconstruction,” “surgical papillary regeneration,” and “hyaluronic acid injection.” Studies that have involved surgical techniques for interdental papilla regeneration as well as less invasive surgical procedure such as hyaluronic acid injections are comprehensively reviewed in this article. Techniques such as tunnelling and coronally advanced flap appear to have better success rate compared to other techniques. In view of graft, connective tissue graft resulted in successful interdental papilla regeneration with papillary fill maintained over long-term compared to concentrated growth factors. A less invasive option would be hyaluronic acid injection, but with less success rate compared to surgical procedures. However, the results were limited by the lack of standardised method to measure successful interdental papilla regeneration. This article comprehensively reviews the updates on interdental papilla regeneration techniques.
Volar Lunate Dislocation Causing Secondary Carpal Tunnel Syndrome: A Case Report

Published: October 2023

Background Failure of carpal tunnel release is an uncommon occurrence with unique pathologies that may impede proper diagnosis and treatment. Symptoms are most often attributed to an inadequate release of the transverse carpal ligament or pathologic scar tissue resultant of the primary decompression.

Case Description In this report, we describe the case of a 79-year-old male with a history of scaphoid lunate advanced collapse and a prior carpal tunnel decompression presenting with worsening right wrist function and new right palmar mass. The patient had no significant antecedent trauma, and clinical workup revealed volar dislocation of the lunate. After failed conservative treatment and multiple ultrasound-guided corticosteroid injections, the patient was successfully treated surgically with carpal tunnel release, tenosynovectomy, and lunate excision.

Literature Review Volar lunate dislocation without a traumatic mechanism is rare. Progressive carpal destabilization and volar subluxation is not a commonly reported cause of secondary carpal tunnel symptoms. Isolated reports in the literature have been published with nearly identical presentations. Kamihata et al reported a patient, with a history of carpal tunnel decompression, presenting with numbness and tingling in her right hand without traumatic injury. A displaced lunate was found to abut the flexor tendons and median nerve. Ott et al further reported an atraumatic lunate dislocation and palmar swelling 4 weeks after a carpal tunnel release.

Clinical Relevance In the setting of existing arthritic degeneration, carpal tunnel release may destabilize the carpus and predispose patients to carpal dislocation. Further research is required to understand the risks associated with this instability leading to lunate dislocations secondary to carpal tunnel release.

Published: October 2023

Purpose Management of ulnar-sided wrist pain is difficult due to the complexity of the anatomy and the similarity of the signs and symptoms of possible diagnoses. The study's main purpose is to examine the effect of arthroscopic triangular fibrocartilage (TFC) repair on untreated extensor carpi ulnaris (ECU) tendinitis and synovitis.

Methods Thirteen patients who underwent arthroscopic TFC repair in our clinic and preoperatively demonstrated ECU tendon pathology with magnetic resonance imaging (MRI) were included in the retrospective study. Pre- and postoperative visual analog scale (VAS), pre- and postoperative tendinitis and synovitis, postoperative Mayo and patient-rated wrist evaluation score, postoperative grip strength of the operated and control sides, short and long diameters of the ECU tendon in ultrasonography were recorded.

Results The mean age of 13 patients (9 females and 4 males) was 39.54 ± 13.54, and the mean follow-up period was 26 ± 7.25 months. While there was no significant difference between pre- and postoperative tendinitis or synovitis levels, VAS decreased significantly (8.46 ± 1.33 vs. 3.00 ± 2.31, p = 0.0016). While the grip strength was 21.78 ± 7.83 on the control side, it was 18.28 ± 7.51 on the surgery side, being significantly lower (p = 0.0252). Ulnar variance did not affect tendinitis or synovitis. Short and long diameters of ECU were similar for the operated and control sides. While the short diameter did not affect the synovitis–tendinitis score, the bigger the long diameter, the higher the synovitis score (rho = 0.5162).

Conclusion In the presence of ECU, tendon pathologies accompanying TFC lesions, additional surgical interventions are mandatory as arthroscopic TFC repair has no significant effect on the healing of ECU.

Environmentally Sustainable Endoscopy Practices
Authors: Jain Mayank
Published: October 2023

Climate change affects each and every one of us and has far reaching consequences. As healthcare providers and responsible citizens, it is our duty to make our practices environmentally sustainable. Endoscopy practice involves frequent use of single-use items, resource-heavy decontamination practices, water consumption, patient and staff travel as well as high electricity consumption. The present review highlights the measures that can be taken to reduce the carbon footprint of endoscopy practice. Proper waste management, judicious use of electricity, proper selection of cases for anesthesia and biopsy, and appropriate use of noninvasive tests in practice are discussed in the review.
In situ observation of morphological change of Pd-based bimetallic nanoparticles synthesized by co-sputtering
Authors: Nakamura N. , Matsuura K. , Ishii A.
Published: October 2023

The formation process of Pd-based bimetallic nanoparticles synthesized by co-sputtering is investigated by performing in situ morphological observation using resistive spectroscopy. The segregation of the metal with lower surface energy on the nanoparticle surface is observed, and it is found that the formation process of the alloy nanoparticles tends to be similar to that of the nanoparticles composed of the core metal even when the atomic fraction of the shell metal is higher than that of the core metal. The co-sputtering process is simulated by the molecular dynamics analysis, and the observed formation process is theoretically confirmed.
