Published: January 2023

The genetic diversity of wild thyme (Thymus capitatus) which growing in southern parts of Al-Jabal Al-Akhdar region, Libya was studied by using cluster analysis of morphological traits (flower measurements). This study was aimed to establish the phylogenetic relationships based on floral parameters among accessions of thyme (T.capitatus). The five populations (accessions) of Libyan thyme were assigned into two clusters (clades) at the critical distance value of 22%. The 1stcluster contained three populations that were included white-flowered, dotted white-flowered and violet-flowered accession, then the 1st cluster was divided into two sub-clusters by the critical distance value of 5%, the first sub-cluster contained two populations (white-flowered, dotted white-flowered accession). While, the second sub-cluster contained one population (violet-flowered accession). The 2nd cluster contained two populations which were purple-flowered and mosaic-flowered accessions. In conclusion, The flower measurements can be a preliminary tool to classify Libyan thyme (T.capitatus), and floral parameters can be used in the classification of Libyan thyme accessions (populations).
Prevalence and Distribution of Pine Processionary Moth (Thaumetopoea pityocampa) in Shahat’s Aleppo Pine (Pinus halepensis) Plantations, Al-JabalAl-Akhdar, Libya
Authors: Alsanousi Attia , Hamad Sheip Younes 
Published: January 2023

The current study aims at investigating the spatial distribution of pine processionary moth (PPM) in parts of Al-Jabal Al-Akhdar region in Libya (in Shahat area). Two Pinus halepensis stands in the area (in Al-Mansurra and the ancient city of Cyrene) were chosen for field data collection. Growth parameters for pine trees including; tree height, crown height, diameter at breast height, stand density level, location within the stand, health condition, in addition to the observed number of PPM nests per tree were recorded. Pearson correlation coefficient analysis and variance analysis were applied to assess the relationship between obtained variables, and evaluate growth conditions for both stands. Results revealed relatively better growth conditions at Al-Mansurra site compared to Cyrene site. Moreover, PPM nests occurrence was positively correlated with trees growing isolated or on the stand edge (r = 0.54, P value <.001), and negatively correlated with tree height (r = - 0.4, P value <.001) emphasizing more dispersal rate among young pine trees. Crown height, dbh, and tree’s health condition showed no significant effect on PPM spread in the area. In-depth investigations of the population dynamics of PPM are highly recommended to provide insights into their spatial distribution in the region.

AIM- To evaluate the knowledge, awareness and attitude of the dentist from North India towards Silver Diamine Fluoride (SDF) use in preventing dental caries. MATERIALS AND METHODS- An online survey was conducted among dentists of North India using online questionnaire to assess the knowledge, experience, and attitude of dentists regarding the use of SDF. 107 dentists participated in the online survey. Data obtained were analysed statistically. RESULTS-Most participants revealed they were somewhat taught about SDF. 29 % of the participants agreed that SDF can be used as an alternative to the conventional method of caries removal. Nearly about 32.7 % of the participants do not know regarding the application protocol interval for SDF. CONCLUSION- Knowledge about SDF among dental practitioners in North India was low to moderate. Increasing SDF knowledge among dentists may serve as an alternative for treating young patients who cannot co-operate with the traditional dental treatment.

Circonstances de jeu et usages rythmiques d’une pratique et d’un répertoire éclatés : le cas du tambour malbar à la Réunion
Authors: Folio-Paravéman Stéphanie 
Published: January 2023

Le tambourmalbar est un instrument qui, à La Réunion, est généralement considéré comme sacré de par son usage principalement réservé au sein des cérémonies religieuses hindoues. Mais depuis une trentaine d’années, cette tradition musicale indo-réunionnaise connaît une certaine expansion de sa pratique et de son répertoire. En effet, l’instrument peut tout aussi bien être utilisé au cours de rituels hindous que dans des circonstances qui s’émancipent du contexte initial strictement religieux.
Dans le cadre de cet article, trois espaces caractéristiques seront abordés en vue d’appréhender les différents ressorts d’une telle pluralité situationnelle : d’une part, le contexte hindou, c’est-à-dire l’espace religieux, sera abordé, pour ensuite investiguer d’autre part le contexte créole, plus précisément l’espace du spectacle avec l’exemple de la troupe « Les Tambours Sacrés de La Réunion » et celui du concert de maloya.
La fonction religieuse à laquelle le tambourmalbar est ordinairement rattaché conditionne en grande partie le caractère sacré de cet instrument ; d’après certains informateurs interrogés à ce sujet lors d’enquêtes de terrain menées à La Réunion depuis 2014, ce tambour est en effet non seulement sacré en lui-même, mais également par le rôle qu’il joue au sein du contexte musical rituel : celui de marquer la présence des divinités qui réagissent à son appel.
Dans le recueil des discours, il s’avère que les dires relatifs au sacré de l’objet s’élèvent à plusieurs niveaux. En effet, bien que les rythmes produits dans les divers contextes de jeu soient plus ou moins éloignés de ceux qui sont en usage dans la sphère religieuse, les modes de sécularisation du tambourmalbar divise les Réunionnais. Quel(s) sens et quelle(s) valeur(s) revêt le tambourmalbar lorsqu’il est utilisé dans l’une ou l’autre des situations observées ? Comment s’en trouve alors affecté le répertoire musical de cet instrument ? L’usage rythmique est-il réellement susceptible de caractériser une certaine circonstance de jeu ? Une fois analysées les spécificités propres aux trois espaces de jeu ci-dessus mentionnés, sera proposée une approche de ces situations musicales par l’étude d’une pratique et d’un répertoire éclatés susceptible de révéler les enjeux identitaires que suscite chacun des usages dont le tambour malbar fait aujourd’hui l’objet à La Réunion.

Published: January 2023

ImportanceAlthough access to pediatric cancer care has implications for use of such care and patient outcomes, little is known about the geographic accessibility of pediatric cancer care and how it may vary by population characteristics across the continental US.ObjectiveTo estimate the travel time to pediatric cancer care settings in the continental US, identify potential disparities among subgroups of children and adolescents and young adults (AYAs), and identify areas needing improved access to pediatric cancer care.Design, Setting, and ParticipantsThis cross-sectional study collected data from August 1 to December 1, 2021. Pediatric oncologists’ service locations in 2021 served as the pediatric cancer care settings, data for which were scraped from 2 websites containing information about health professionals. Demographic characteristics for younger children and AYAs aged 0 to 21 years were obtained from the 2015 to 2019 American Community Survey 5-year estimates. Data were analyzed from January 1 to April 31, 2022.Main Outcomes and MeasuresThe main outcome was the travel time from geographic centroids of zip code tabulation areas to the nearest pediatric oncologist. The median (IQR) travel times for each demographic subgroup were estimated. Per capita pediatric oncologist supply was calculated by dividing the total number of pediatric oncologists for each state or US Census division by its population.ResultsOf the 90 498 890 children and AYAs included in the study, 63.6% were estimated to travel less than 30 minutes and 19.7% to travel between 30 and 60 minutes (for a total of 83.3%) to the nearest pediatric oncologist. Median (IQR) travel times were longest for the American Indian or Alaska Native pediatric population (46 [16-104] minutes) and residents of rural areas (95 [68-135] minutes), areas with high deprivation levels (36 [13-72] minutes), and the South (24 [13-47] minutes) and Midwest (22 [11-51] minutes) compared with the general population of children and AYAs. The pediatric oncologist supply was lowest in Wyoming (0 oncologists per 100 000 pediatric population) and highest in Washington, DC (53.3 oncologists per 100 000 pediatric population). Pediatric oncologist supply across Census divisions was lowest in the Mountain division (3.3 oncologists per 100 000 pediatric population) and highest in the New England division (8.1 oncologists per 100 000 pediatric population).Conclusions and RelevanceResults of this study showed that most children and AYAs in the continental US had adequate access to pediatric cancer care, although disparities existed among racial and ethnic groups and residents in rural areas, areas with high deprivation levels, and some Southern and Midwestern states. Reducing these disparities may require innovative approaches, such as expanding the capabilities of local facilities and creating partnerships with adult oncology centers and primary care physicians.
DigiFuehr 2.0: Novel insights for digital leadership
Authors: Claassen Kevin , Rodil Dos Anjos Dominique , Kettschau Jan Patrick , Wrede Sammy Joelle Shirley , Broding Horst Christoph 
Published: January 2023

Abstract

Objectives
Against the background of e-government, it is discussed whether self-organization represents an independent component of digital leadership. Addressing this research question, the instrument “DigiFuehr” is being expanded to include the aspects of self-determination and coordination. The aim is to test the model quality of three adapted scales against the already established support-focusing version.

Methods
Based on an online survey of n = 422 employees at visual display unit workstations in German municipal administrations in April 2022, the original version of DigiFuehr as well as one reduced and two extended versions were validated considering their local and global model fit.

Results
All four scales show a good local fit with regard to internal consistency (Cronbach’s α), discriminatory power, and dimensionality. Only the scale extended by two items also offers a sufficient global fit and is thus most suitable as a predictor for psychological stress, work satisfaction, and satisfaction with the professional exchange during homeworking.

Conclusions
With “DigiFuehr 2.0”, an improved version of the original scale is available. Self-organization is not a component independent of the support dimension, but a further important indicator of a latent digital leadership culture. Neither should come at the expense of the other.
Building bridges for inspired action: On landscape restoration and social alliances

Published: January 2023

Abstract

Participatory approaches are linked to landscape restoration (LR) success, but not all participatory approaches are created equal. Engagement approaches that invest in transformative stakeholder and governance processes can create the right conditions for long‐term LR commitment.

A large‐scale LR initiative in Spain, namely AlVelAl, illustrates how collective action can be activated through inspiration, trust and hope, which, in turn, can be cultivated through the application of social schemes designed to support inclusive stakeholder engagement processes and programmes.

Collective agency and inspiration matter for activating and sustaining LR actions and outcomes. Multi‐stakeholder partnerships that speak to human agency, inclusivity and trust between actors can help create a deeper shared meaning, a place‐based sense of belonging that encourages cohesive landscape stewardship.

AbstractDue to the surface inhomogeneity of the solid supports, direct growth of uniform bimetallic nanoparticles (NPs) with controllable structure and size thereon is particularly challenging. Herein, a surface‐confinement strategy is reported to directly prepare ultrafine bimetallic PtM NPs (MFe, Cu, and Co) with structure of core‐shell or intermetallic compounds on an N functionalized carbon support (NC). It is found that the N species of NC support can atomically disperse metal cations of precursors, which largely renders uniform nucleation and growth of bimetallic NPs and fine structure modulation of them. In another regard, metal transfer is confined to a narrow region on NC via N‐mediation, hence greatly favoring localized particle growth and formation of ultrafine bimetallic NPs. Remarkably, the ultrafine 3.1 ± 0.7 nm intermetallic Pt3Fe NPs on NC displayed excellent catalytic activity and durability toward electrochemical hydrogen evolution reaction.
Amphiphilic Dendrimer Doping Enhanced pH‐Sensitivity of Liposomal Vesicle for Effective Co‐delivery toward Synergistic Ferroptosis–Apoptosis Therapy of Hepatocellular Carcinoma

Published: January 2023

AbstractFerroptosis, characterized by the accumulation of reactive oxygen species and lipid peroxides, has emerged as an attractive strategy to reverse drug resistance. Of particular interest is the ferroptosis–apoptosis combination therapy for cancer treatment. Herein, a nanoplatform is reported for effective co‐delivery of the anticancer drug sorafenib (S) and the ferroptosis inducer hemin (H), toward synergistic ferroptosis–apoptosis therapy of advanced hepatocellular carcinoma (HCC) as a proof‐of‐concept study. Liposome is an excellent delivery system; however, it is not sufficiently responsive to the acidic tumor microenvironment (TME) for tumor‐targeted drug delivery. The pH‐sensitive vesicles are therefore developed (SH‐AD‐L) by incorporating amphiphilic dendrimers (AD) into liposomes for controlled and pH‐stimulated release of sorafenib and hemin in the acidic TME, thanks to the protonation of numerous amine functionalities in AD. Importantly, SH‐AD‐L not only blocked glutathione synthesis to disrupt the antioxidant system, but also increased intracellular Fe2+ and ·OH concentrations to amplify oxidative stress, both of which contribute to enhanced ferroptosis. Remarkably, high levels of ·OH also augmented sorafenib‐mediated apoptosis in tumor cells. This study demonstrates the efficacy of ferroptosis–apoptosis combination therapy, as well as the promise of the AD‐doped TME‐responsive vesicles for drug delivery in combination therapy to treat advanced HCC.

AbstractAlthough immunotherapy has revolutionized oncotherapy, only ≈15% of head and neck squamous cell carcinoma (HNSCC) patients benefit from the current therapies. An immunosuppressive tumor microenvironment (TME) and dysregulation of the polycomb ring finger oncogene BMI1 are potential reasons for the failure. Herein, to promote immunotherapeutic efficacy against HNSCC, an injectable nanocomposite hydrogel is developed with a polymer framework (PLGA‐PEG‐PLGA) that is loaded with both imiquimod encapsulated CaCO3 nanoparticles (RC) and cancer cell membrane (CCM)‐coated mesoporous silica nanoparticles containing a peptide‐based proteolysis‐targeting chimeras (PROTAC) for BMI1 and paclitaxel (PepM@PacC). Upon injection, this nanocomposite hydrogel undergoes in situ gelation, after which it degrades in the TME over time, releasing RC and PepM@PacC nanoparticles to respectively perform immunotherapy and chemotherapy. Specifically, the RC particles selectively manipulate tumor‐associated macrophages and dendritic cells to activate a T‐cell immune response, while CCM‐mediated homologous targeting and endocytosis delivers the PepM@PacC particles into cancer cells, where endogenous glutathione promotes disulfide bond cleavage to release the PROTAC peptide for BMI1 degradation and frees the paclitaxel from the particle pores to elicit apoptosis meanwhile enhance immunotherapy. Thus, the nanocomposite hydrogel, which is designed to exploit multiple known vulnerabilities of HNSCC, succeeds in suppressing both growth and metastasis of HNSCC.
Lithium Batteries and the Solid Electrolyte Interphase (SEI)—Progress and Outlook
Authors: Adenusi Henry , Chass Gregory A. , Passerini Stefano , Tian Kun V. , Chen Guanhua 
Published: January 2023

AbstractInterfacial dynamics within chemical systems such as electron and ion transport processes have relevance in the rational optimization of electrochemical energy storage materials and devices. Evolving the understanding of fundamental electrochemistry at interfaces would also help in the understanding of relevant phenomena in biological, microbial, pharmaceutical, electronic, and photonic systems. In lithium‐ion batteries, the electrochemical instability of the electrolyte and its ensuing reactive decomposition proceeds at the anode surface within the Helmholtz double layer resulting in a buildup of the reductive products, forming the solid electrolyte interphase (SEI). This review summarizes relevant aspects of the SEI including formation, composition, dynamic structure, and reaction mechanisms, focusing primarily on the graphite anode with insights into the lithium metal anode. Furthermore, the influence of the electrolyte and electrode materials on SEI structure and properties is discussed. An update is also presented on state‐of‐the‐art approaches to quantitatively characterize the structure and changing properties of the SEI. Lastly, a framework evaluating the standing problems and future research directions including feasible computational, machine learning, and experimental approaches are outlined.
