From out of the Blue: Swift Links 2002es-like, 2003fg-like, and Early Time Bump Type Ia Supernovae

Published: May 2024

We collect a sample of 42 Type Ia supernovae (SNe Ia) with Swift UV photometry and well-measured early time light-curve rises and find that 2002es-like and 2003fg-like SNe Ia have different prepeak UV color evolutions compared to normal SNe Ia and other spectroscopic subtypes. Specifically, 2002es-like and 2003fg-like SNe Ia are cleanly separated from other SNe Ia subtypes by UVM2 − UVW1 ≳ 1.0 mag at t = − 10 days relative to B-band maximum. Furthermore, the SNe Ia that exhibit nonmonotonic bumps in their rising light curves, to date, consist solely of 2002es-like and 2003fg-like SNe Ia. We also find that SNe Ia with two-component power-law rises are more luminous than SNe Ia with single-component power-law rises at prepeak epochs. Given the similar UV colors, along with other observational similarities, we discuss a possible progenitor scenario that places 2002es-like and 2003fg-like SNe Ia along a continuum and may explain the unique UV colors, early time bumps, and other observational similarities between these objects. Ultimately, further observations of both subtypes, especially in the near-infrared, are critical for constraining models of these peculiar thermonuclear explosions.
The Dynamic, Chimeric Inner Disk of PDS 70

Published: May 2024

Transition disks, with inner regions depleted in dust and gas, could represent later stages of protoplanetary disk evolution when newly formed planets are emerging. The PDS 70 system has attracted particular interest because of the presence of two giant planets in orbits at tens of astronomical units within the inner disk cavity, at least one of which is itself accreting. However, the region around PDS 70 most relevant to understanding the planet populations revealed by exoplanet surveys of middle-aged stars is the inner disk, which is the dominant source of the system’s excess infrared emission but only marginally resolved by the Atacama Large Millimeter/submillimeter Array. Here we present and analyze time-series optical and infrared photometry and spectroscopy that reveal the inner disk to be dynamic on timescales of days to years, with occultation by submicron dust dimming the star at optical wavelengths, and 3–5 μm emission varying due to changes in disk structure. Remarkably, the infrared emission from the innermost region (nearly) disappears for ∼1 yr. We model the spectral energy distribution of the system and its time variation with a flattened warm (T ≲ 600 K) disk and a hotter (1200 K) dust that could represent an inner rim or wall. The high dust-to-gas ratio of the inner disk, relative to material accreting from the outer disk, means that the former could be a chimera consisting of depleted disk gas that is subsequently enriched with dust and volatiles produced by collisions and evaporation of planetesimals in the inner zone.
Pinwheel Outflow Induced by Stellar Mass Loss in a Coplanar Triple System

Published: May 2024

We develop a physical framework for interpreting complex circumstellar patterns whorled around asymptotic giant branch (AGB) stars by investigating stable, coplanar triple systems using hydrodynamic and particle simulations. The introduction of a close tertiary body causes an additional periodic variation in the orbital velocity and trajectory of the AGB star. As a result, the circumstellar outflow builds a fine non-Archimedean spiral pattern superimposed upon the Archimedean spiral produced by the outer binary alone. This fine spiral can be approximated by off-centered circular rings that become tangent to each other at the location of the Archimedean spiral. The superimposed fine pattern fades out relatively quickly as a function of distance from the center of the system, in contrast to the dominant Archimedean spiral pattern, which presents a much slower fractional density decrease with radius. The different rates of radial decrease of the density contrast in the two superimposed patterns, coupled with their different time and spatial scales, lead to an apparent, but illusory radial change in the observed pattern interval, as has been reported, for example, in CW Leo. The function describing the detailed radial dependence of the expansion velocity is different in the two patterns, which may be used to distinguish them. The shape of the circumstellar whorled pattern is further explored as a function of the orbital eccentricity and the inner companion’s mass. Although this study is confined to stable, coplanar triple systems, the results are likely applicable to moderately noncoplanar systems and open interesting avenues for studying noncoplanar systems.
Chondrule Destruction via Dust Collisions in Shock Waves
Authors: Matsumoto Yuji , Kurosawa Kosuke , Arakawa Sota
Published: May 2024

A leading candidate for the heating source of chondrules and igneous rims is shock waves. This mechanism generates high relative velocities between chondrules and dust particles. We have investigated the possibility of the chondrule destruction in collisions with dust particles behind a shock wave using a semianalytical treatment. We find that the chondrules are destroyed during melting in collisions. We derive the conditions for the destruction of chondrules and show that the typical size of the observed chondrules satisfies the condition. We suggest that the chondrule formation and rim accretion are different events if they are heated by shock waves.
Evidence for Plasmoid-mediated Magnetic Reconnection during a Small-scale Flare in the Partially Ionized Low Solar Atmosphere

Published: May 2024

Magnetic reconnection plays a crucial role in the energy release process for different kinds of solar eruptions and activities. The rapid solar eruption requires a fast reconnection model. Plasmoid instability in the reconnecting current sheets is one of the most acceptable fast reconnection mechanisms for explaining the explosive events in the magnetohydrodynamics (MHD) scale, which is also a potential bridge between the macroscopic MHD reconnection process and microscale dissipations. Plenty of high-resolution observations indicate that the plasmoid-like structures exist in the high-temperature solar corona, but such evidences are very rare in the lower solar atmosphere with partially ionized plasmas. Utilizing joint observations from the Goode Solar Telescope and the Solar Dynamics Observatory, we discovered a small-scale eruptive phenomenon in NOAA Active Region 13085, characterized by clear reconnection cusp structures, supported by nonlinear force-free field extrapolation results. The plasmoid-like structures with a size of about 150 km were observed to be ejected downward from the current sheet at a maximum velocity of 24 km s−1 in the Hα line wing images, followed by enhanced emissions at around the postflare loop region in multiple wavelengths. Our 2.5D high-resolution MHD simulations further reproduced such a phenomenon and revealed reconnection fine structures. These results provide comprehensive evidences for the plasmoid-mediated reconnection in partially ionized plasmas, and suggest a unified reconnection model for solar flares with different length scales from the lower chromosphere to the corona.

Beauté et modernité
Authors: Morel Journel Guillemette
Published: May 2024

La catégorie du beau n’est guère de mise dans les arts et l’architecture d’aujourd’hui. Il y eut pourtant un épisode de l’histoire de l’architecture où un architecte s’est emparé de la beauté pour en faire frontalement un enjeu de la modernité, et ce au péril de sa réputation. En 1929, Le Corbusier répondit à ses détracteurs de la Neue Sachlichkeit (Nouvelle Objectivité), qui l’accusaient d’avoir conçu un projet académique pour le Mundaneum de Genève en forme de ziggourat, par un long texte significativement intitulé « Défense de l’architecture ». Un des slogans les plus marquants en était : « L’utile n’est pas le beau. » En n’hésitant pas à affronter de plein fouet l’ire de ses compagnons de route, Le Corbusier affirme que la beauté transcende les postures idéologiques et formalistes et garde, quels que soient les styles par lesquels elle est exprimée, une pertinence au cœur même du projet moderne.
The Trauma of Separation: Lifelong Health Implications on Children
Authors: Wallace Carmelle
Published: May 2024

In the United States, there are millions of globally displaced children who travel with family to seek immigration relief, many of whom have experienced family separation or live under the constant threat of separation. Family separation constitutes a significant trauma with lifelong impacts on a child's mental health, physical health, and development. This review provides a summary of the various contexts within which family separation occurs as well as the current literature on long-term health sequelae. These include mental illness, externalizing behaviors, developmental challenges, family stability, economic impacts, and educational attainment. Given the number of newcomer children in the US, it is paramount that pediatric clinicians develop a holistic understanding of their needs and the effects of separation to provide evidence-based care and to advocate for the prevention of this trauma for all future migrant families.

Published: May 2024

The increase in forcibly displaced populations seeking refuge in the United States has been met with fragmented, chaotic, and highly politicized responses to the detriment of migrants and receiving communities alike. Migrants encounter compounding systemic barriers to accessing basic resettlement resources. Expanding on pandemic-era innovations can strengthen social safety net infrastructure as a whole. Pediatricians are a potential early touchpoint for newly arrived families, providing an opportunity to support their specific health needs, refer to critical safety net services, and advocate for improved systems and policies.

What Kind of Non-Realism is Fictionalism?
Authors: Gan Nathaniel
Published: May 2024

Fictionalists about a kind of disputed entity aim to give a face-value interpretation of our discourse about those entities without affirming their existence. The fictionalist’s commitment to non-realism leaves open three options regarding their ontological position: they may deny the existence of the disputed entities (anti-realism), remain agnostic regarding their existence (agnosticism), or deny that there are ontological facts of the matter (ontological anti-realism). This paper outlines a method of adjudicating between these options and argues that fictionalists may be expected to hold preferences between them. The typical arguments and motivations for fictionalism lead naturally to a practice-based metaontological framework under which our practices regarding a kind of disputed entity might inform our ontological beliefs about those entities. When that framework is applied to fictionalism, it is found that the usual motivations for fictionalism lead naturally, though not decisively, to ontological anti-realism. And, where there are reasons against ontological anti-realism, fictionalism leans more toward anti-realism than agnosticism.
What are the impacts of teleworking on activity-travel behaviour? A text mining study
Authors: Pigalle Eleonore
Published: May 2024

This study aims to understand how teleworking reorganises activity-travel behaviour. While the link between teleworking and mobility was widely studied, most of the research focused on commuting practices by comparing teleworkers to non-teleworkers. However, the coping strategies of teleworkers and their household members (e.g. reorganisation of activities according to the days of the week, and associated travel behaviour) remain insufficiently studied. With a systemic approach to interpersonal relationships, and their activities in the different spheres of their lives (i.e. professional, family, social and personal), the Reinert method we used (top-down hierarchical clustering) confirms and develops our knowledge about the rebound effects of teleworking. Our findings confirm that the work/telework sphere has a structuring role in the daily activity schedule and is associated with other travel motives (e.g. shopping, leisure or other personal activities). Teleworking appears as an adjustment variable, as it offers more freedom, and facilitates the organisation and reconciliation of activities in the different spheres of daily life. Thus, teleworking transforms individuals’ choices, habits and patterns of activities and travel within the household.
Conformist singularities. Standardized discourses on the local specificities of urban projects
Authors: Adam Matthieu
Published: May 2024

This article addresses a paradox: whereas urban projects are meant to have a specific local (historical, geographical, and cultural) color, the projects themselves and the discourse about them are highly standardized. Collected through semi-structured interviews, the discourses of the designers (architects, urban planners, landscape architects, promoters, and project managers) of two urban projects in France are scrutinized using discourse analysis (textual statistics) and content analysis (qualitative approach). First, the study reveals the uniformity of these actors’ discourse: textual statistics show a striking similarity in discourse across the two sites even if the differences among professions are more apparent. Second, it highlights the role of local specificities within this uniformity: the qualitative analysis shows that the discourse remains standardized despite its purpose to highlight singularities. Finally, the paper reveals how the actors themselves perceive this paradox and maintain a critical distance regarding the dominant trends in the production of contemporary cities.
Planning for climate change with the best of intentions... Analyzing the content of plans and planners’ rationale for adaptation
Authors: Chavez Saray , Molines Nathalie , Chancibault Katia , Gouvello Bernard de
Published: May 2024

In France, local urban plans (PLUi) can convey drivers for climate change adaptation, e.g. greening and limitation of soil sealing to reinforce stormwater management. However, translating adaptation measures into plans is not always easy for planners to effectively communicate adaptation. We create an analysis method, specifically designed for the sustainable development project (PADD), a key document of the PLUi, in order to understand its adaptation approach. The PADD examined is that of the PLUi of Nantes metropolis in France. The first part of the method has been published; here, we develop the last two steps of the method, which consist of a thematic analysis applied to the corpus and a cross-analysis of results. The findings reveal seven major intentions for adaptation. Specific actions were more difficult to identify; however, four areas of practical application emerged: vegetation, water, soil and building. Furthermore, we questioned local planners to get a complete sense of their rationale to address adaptation. Creators and agents result in being aware of the challenges and can identify concrete and synergistic adaptive actions; however, it is unclear how they would measure achievement of PADD objectives. The results may provide useful information to determine whether PADDs are conducive to adaptation.
Du travail émotionnel au travail de santé
Authors: Lhuilier Dominique
Published: May 2024

Les transformations du traitement des émotions au travail se signalent par un glissement de la proscription des émotions à leur prescription, et ce, sur fond de ce nouveau modèle managérial de gestion des subjectivités. La notion de travail émotionnel, entendu comme travail de contrôle et production des émotions conformes aux exigences de la situation de travail, met l’accent sur son versant prescriptif. Nous explorons ici une autre face du traitement de l’émotion, non plus seulement du côté de la normalisation mais de la normativité. Le travail – au sens d’activité – implique un sujet et sa vie affective. Le fil tiré conduit à explorer les épreuves psychiques du travail et leur impact sur la santé. Dans cette perspective, nous développerons la part de travail émotionnel indexé au travail de santé. Le concept de travail de santé cherche à rendre compte de la construction de la santé tricotée dans l’activité professionnelle.
De l’expérience du cancer à l’activité de patiente-partenaire : travailler (avec) les émotions dans l’accompagnement des patientes en cancérologie
Authors: Delaunay Marine , Jacques Béatrice
Published: May 2024

L’implication de patientes-partenaires dans des équipes soignantes rejoue un processus d’attribution et de délégation des tâches relatives à la prise en charge des patientes. Ces patientes-partenaires réalisent un travail émotionnel dans le quotidien de leurs missions d’accompagnement des patient·e·s atteint·e·s de cancer, qui a été présent tout au long du processus de leur reconversion professionnelle. Dans la mesure où les espaces médicaux et scientifiques ont toutefois généralement tendance à offrir un accueil réservé à l’expression des émotions, les patientes-partenaires sont amenées à mobiliser différentes stratégies de régulation sur elles et sur les patient·e·s qu’elles accompagnent. Ce travail émotionnel participant de l’équilibre des relations entre patient·e·s et soignant·e·s, les émotions constituent, en définitive, tout autant un support de valorisation de l’activité d’accompagnement des patient·e·s, qu’une forme d’acculturation au monde des soignants. Si le temps passé à réaliser ce travail montre qu’il est une des composantes essentielles du processus de professionnalisation de ce nouveau métier, cela vient aussi réinterroger le(s) modèle(s) relationnels et pourrait assouplir le rapport des soignants aux émotions.
Some Do Not… et No More Parades de Ford Madox Ford : l’impossible cartographie
Authors: Vialle Elisabeth
Published: May 2024

Lorsque Ford Madox Ford entreprend la rédaction de sa tétralogie sur la Première Guerre mondiale, Parade’s End (1924-1928), c’est pour rendre compte de la violence faite aux corps des combattants et des civils, ainsi qu’à la terre et aux paysages européens alors que vacille l’ordre ancien. Parade’s End est traversé par la crise politique, épistémologique, esthétique qui ébranle l’Europe et trouve son expression dans l’image de la faille, de la béance, image géologique reprise au sein même d’un texte saisi par la fragmentation ou le dédoublement. À la question essentielle de la représentation et de l’aporie dont parlent Benjamin et Bataille, Ford répond par l’image de la carte (géographique ou militaire) sur laquelle tout repère a disparu : « The whole map of the embattled world ran out in front of him – as large as a field. An embossed map in papier mâché – a ten-acre field of embossed papier mâché […] ». Les cartes d’état-major qui ne disent plus que les villes et villages détruits, engloutis sous terre, se trouvent métaphoriquement reproduites à la surface d’un texte haché, troué, entrecoupé de silences qui sont également ceux de la mémoire lacunaire du personnage central, Christopher Tietjens. À partir de l’image saisissante du papier mâché, Ford superpose également une multiplicité de cartes symboliques dont le corps de Tietjens : point aveugle de sa conscience au début de la tétralogie, il est ignoré et invisible, comme absent de sa carte ontologique et incarne la fracture du monde et du sujet. Informe au sens propre du terme, il redevient, lors d’une expérience cathartique, solide, contenu, carte ultime enfin.
Failles et ruptures dans The Haunting of Hill House de Shirley Jackson (1959) et Mike Flanagan (2018) : le cri et l’irreprésentable
Authors: Cregut Céline
Published: May 2024

Si l’adaptation audio-visuelle par Mike Flanagan du roman de Shirley Jackson The Haunting of Hill House, paru en 1959, peut surprendre par la manière dont elle dévie de la trame narrative originelle, Flanagan, par sa maîtrise des possibilités de l’image et du son, traduit parfaitement l’horreur qui est au cœur du roman. Les représentations du surnaturel, qui sont à la fois subtiles et très violentes dans The Haunting of Hill House, sont au cœur de la série que Flanagan a réalisée pour Netflix. Les questions centrales du roman, dont le surnaturel se fait la manifestation, y sont ainsi magnifiées au point où la narration semble parfois fendue, déchirée par la violence de l’image et du son. Ces failles (volontaires) dans la narration déjà fragmentée de la série permettent de révéler, ponctuellement, l’intensité de la détresse intime qui caractérisait déjà Eleanor, personnage principal du roman de Shirley Jackson, et que subit aussi Nell, son incarnation dans la série de Mike Flanagan. Bien loin d’un simple récit de fantômes et de maison hantée, tant le roman que son adaptation révèlent une horreur plus profonde et plus intime, celle d’une personne aliénée par le trauma, tout en exploitant les possibilités esthétiques et narratives du surnaturel. Ainsi, la série de Mike Flanagan offre un questionnement sur la représentation par le texte et l’image d’une détresse subjective et infigurable, et propose une solution (certes éphémère) à ce questionnement par un cri unique : une déchirure sensorielle de la narration qui s’opère par le recours momentané à un cri viscéral, situé au-delà de la logique et le langage. Ce cri poussé non pas par la protagoniste elle-même mais par un témoin de sa souffrance prouve ici la nécessité d’un recours à une représentation oblique de la détresse de Nell, et semble condenser, dans cette déchirure d’une narration alors temporairement suspendue, toute l’ampleur de l’horreur intime que le roman suggérait si subtilement.
Nucleic Acid Sensing by STING Induces an IFN-like Antiviral Response in a Marine Invertebrate
Authors: Li Haoyang , Di Xuanzheng , Wang Sheng , Li Qinyao , Weng Shaoping , He Jianguo , Li Chaozheng
Published: May 2024

The cytosolic detection of pathogen-derived nucleic acids has evolved as an essential strategy for host innate immune defense in mammals. One crucial component in this process is the stimulator of IFN genes (STING), which acts as a vital signaling adaptor, connecting the cytosolic detection of DNA by cyclic GMP-AMP (cGAMP) synthase (cGAS) to the downstream type I IFN signaling pathway. However, this process remains elusive in invertebrates. In this study, we present evidence demonstrating that STING, an ortholog found in a marine invertebrate (shrimp) called Litopenaeus vannamei, can directly detect DNA and initiate an IFN-like antiviral response. Unlike its homologs in other eukaryotic organisms, which exclusively function as sensors for cyclic dinucleotides, shrimp STING has the ability to bind to both double-stranded DNA and cyclic dinucleotides, including 2′3′-cGAMP. In vivo, shrimp STING can directly sense DNA nucleic acids from an infected virus, accelerate IFN regulatory factor dimerization and nuclear translocation, induce the expression of an IFN functional analog protein (Vago4), and finally establish an antiviral state. Taken together, our findings unveil a novel double-stranded DNA–STING–IKKε–IRF–Vago antiviral axis in an arthropod, providing valuable insights into the functional origins of DNA-sensing pathways in evolution.
Functional outcome of close reduction and internal fixation by C-C screw or Steinmann pin fixation of fracture calcaneum
Authors: Dinkar Karuna Shankar , Mittal Vivek , Kapoor Rajat , Sharma Brijesh , Saini Sushil Kumar , Verma Ashutosh
Published: May 2024

Background:

Fracture of calcaneum results in serious and prolonging disability. Considering the high rate of malunion and severe loss of function, it will be better to choose open reduction and internal fixation as a primary mode of treatment for calcaneum fractures.

Materials and Methods:

This study consists of 45 fractures of calcaneum treated by using close reduction and internal fixation and subtalar arthrodesis. Of the 45 fractures, 16 (35.56%) were treated by using the C-C screw within 2 weeks of injury and 29 (64.44%) were treated by using the percutaneous k-wire or Steinmann pin or C-C screw.

Results:

At the final follow-up, the mean AO foot and ankle score score of the patients was 89.28 with P value ≤ 0.0001.

Conclusion:

Early motion prevents stiffness of subtalar joint and ankle joint and leads to early function and psychological rehabilitation. Close reduction and internal fixation by using the C-C screw or Steinmann pin is a safe and effective method for treating displaced intra-articular fracture of calcaneum.
Outcome of home-based rehabilitation program following arthroscopic anterior cruciate ligament reconstruction in nonathletic patient
Authors: Kapoor Rajat , Gahlot Surendra , Singh Gaurav , Yadav Atul , Patel Jaydeep , Pal Chandra Prakash
Published: May 2024

Background:

Rehabilitation following anterior cruciate ligament (ACL) reconstruction is thought to be important by almost all surgeons. It has even been considered by some to be as important as surgery itself. As the surgical procedure for these injuries evolved, so has the rehabilitation. A traditional approach to rehabilitation which focused on delayed weight bearing and mobilization is now being replaced by accelerated rehabilitation which advocates early weight bearing and results in early return to sports.

Materials and Methods:

This is a observational case-control comparative study conducted in our department from September 2019 to February 2021. About 30 cases of more than 20 years of age with comparable matching group are included in our study. Assessment of Lysholm score, International Knee Documentation Committee (IKDC) score, ACL quality of life score, and Tegner activity level is done. Functional assessment was carried out by Carioca test, one leg hop test, and Shuttle test. Assessment of clinical status is done by anterior drawer test, Lachman test, and Pivot shift test.

Results:

All patients participating in study although nonathletic had complaints of instability and giving away episodes of knee in their day to day activities and therefore were considered as candidates for surgery. Following an arthroscopic ACL reconstruction, they were given written home-based protocols with goals and exercises being explained to them at the time of discharge. All the patients participating in the study were able to return to their preinjury activity level as assessed by the Tegner activity scale at the final follow up. Their functional outcome as measured by Lysholm score, IKDC score, and ACL quality of life score was significantly lower when compared to an age, sex, and activity matched control group. The patients functional performance as assessed by one leg hop test, Carioca test, and Shuttle test was also below the level of what was seen in control groups. More than 90% patients had a stable knee as assessed by the anterior drawer test, Lachman test and pivot shift test (29 patients has anterior drawer of ≤5 mm, 27 patients had Lachmann test ≤5 mm and all 30 patients had pivot shift grades in absent or glide category).

Conclusions:

Home-based rehabilitation is an effective method of rehabilitation in low demand individuals following ACL reconstruction. In the future, adequately powered randomized controlled trials are needed to assess the usefulness of one rehabilitation protocol over other in these group of low demand patients.
Bilateral osteochondroma in a child: A rare case report
Authors: Kumar Abhishek , Das Sarthak , Tripathy Saroj Kumar , Malik Archana
Published: May 2024

Osteochondroma has an incidence of 1 in 50,000 and is the most common benign bone tumor, which accounts for 30% (range 20%–50%) of all benign bone tumors. The incidence of osteochondroma is higher in males than females in both its solitary and hereditary forms. Osteochondroma can arise from any bone that develops from enchondral ossification. It commonly involves the long bones, and it rarely involves the ribs. Lesion is common in childhood, with 75%–80% occurring before the age of 20. Here, we report a case of bilateral rib osteochondroma that was presented during infancy.

The translation of Vāgbhaṭa’s Aṣṭāṅgahṛdayam (Sūtrasthāna), the quintessence and their treatment, and the publication of “Kriyākaumudi” and “Cikitsākautukam,” can all be seen as efforts to revive Kerala’s ancient traditions. As his writings were available only in the native Malayalam language, he remained unknown to other parts of the country. He perused innumerable palm leaf manuscripts from private collections and manuscript repositories at Thiruvananthapuram and Kozhikode, the contents of which otherwise would have never appeared in publications. He has not received much recognition and rewards that he deserved, but his insatiable thirst for knowledge has urged him to dig deep into the treasures of Ayurveda.
Vaidyakalanidhi Shri C. N. Narayanan: A revisionist among Ayurveda physicians of Kerala

In Kerala, the traditional knowledge of Ayurveda was meticulously preserved and disseminated by families of Ashtavaidya tradition and other Vaidya (physicians). The branch of Kaumarabhritya (pediatrics) owes much to the detailed treatises such as “Arogyakalpadrumam” by Kaikulangara Rama Varier and “Vaidyatarakam” by Vaidyakalanidhi C. N. Narayanan (CNN). This paper gives an insight into the life and legacy of CNN, a towering figure who enriched the Ayurvedic community through his academic brilliance, leadership, and editorial prowess. CNN, hailing from a traditional Vaidya family in the central region of contemporary Kerala in India, holds a distinguished position as a Balachikitsaka (pediatrician). His significant contributions to the field of Kaumarabhritya are encapsulated in his seminal work, Vaidyatarakam. This magnum opus delves into unique formulations designed to combat prevalent diseases of his era, such as Karappan (a skin disorder), Romantika Jwara (measles), Nilankari Chuma (whooping cough), and Pilla Vata (polio), among others. He played a crucial role in shaping discussions on professional, academic, and social aspects of Ayurveda. Contrary to the custom of preserving traditional and professional knowledge as a family secret, he devoted himself to spreading his extensive clinical and practical experience. CNN’s tireless efforts have not only enriched the field of Ayurveda but have also contributed to its wider dissemination and understanding.
Success predictive factors of teeth subjected to autotransplant: An umbrella review
Authors: Pineda-Vélez Eliana , Vivares Anny M. , Casillas-Castillo Jocelyne Valeria
Published: May 2024

Introduction:

A dental autotransplant is a controlled case of dental avulsion based on the transplantation of erupted teeth within the same individual, from one place to another, in sites where an extraction was performed or that were surgically prepared. Autotransplantation has become a viable method to replace lost teeth since transplanted teeth may operate as fully normal teeth.

Objective:

The objective of this study was to summarize the available scientific evidence regarding predictors of success in autotransplanted teeth.

Materials and Methods:

A systematic review of systematic reviews, known as an umbrella review, was performed. Two calibrated and standardized investigators independently analyzed the quality using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline and evaluated the confidence level and bias review with the Amstar-2 guideline. The PubMed, Embase, and Scopus databases were used. The search was conducted in August 2022 and updated on March 22, 2023. Systematic reviews or meta-analyses carried out from publications on human beings, between 2017 and 2022, were included.

Results:

From 104 achieved, 4 systematic reviews and meta-analyses were assessed. The overall survival of autotransplanted teeth ranged from 81% to 98%, the prevalence of overall inflammatory root resorption ranged from 2.1% to 43%, and the prevalence of ankylosis ranged from 1.2% to 43%. Predictive factors for success identified in the literature included tooth type or root development and clinical intervention factors, including socket preparation, splinting, occlusion control, antibiotic regimen, treatment time of endodontics, and orthodontic treatment.

Conclusions:

The existing evidence on autotransplanted teeth in humans indicates that the survival rate of such teeth involves a series of presurgical and surgical variables. Analyses of factors associated with complications or failures still require primary studies where associations may be made to draw more solid conclusions.

Published: May 2024

Introduction:

The main goal of instrumentation during retreatment is to maintain the original curvature of the canal during retrieval of gutta-percha. The present study evaluates the canal-centering ability of two different retreatment file systems.

Materials and Methods:

Forty extracted single-rooted teeth were decoronated and obturated at the standardized root length of 16 mm. Samples were divided into two groups of each 20 single root teeth and they were instrumented using Solite RS3 Retreatment and ProTaper Retreatment files, respectively. Both pre- and postoperative nano-computed tomography scans were taken, and three-dimensional reconstruction was done for analysis. Sections of both the pre- and postoperative samples were taken at 7 mm, 5 mm, and 3 mm from the apex to calculate the canal-centering ratio. Independent t-test was used for statistical analysis between the two groups.

Results:

Solite RS3 retreatment files showed a significant difference at the 3 levels (P < 0.000) compared to ProTaper retreatment files.

Conclusion:

From the above results, we can conclude that Solite RS3 caused minimal canal transportation and produced a relatively centered preparation in comparison to the ProTaper Retreatment system.
A narrative review on the current uses of artificial intelligence in endodontics
Authors: Bakhsh Abdulaziz A.
Published: May 2024

Artificial intelligence (AI) has been widely introduced to dentistry in the past decade. Its application in endodontics is limited to different areas such as working length determination, morphological assessment, detection of vertical root fracture, and the detection of periapical lesion. Therefore, this study aims to highlight the available evidence for the uses of AI in endodontics. It also presents the current status as well as the future perspectives on the uses of AI and its potential application in everyday practice. A literature search was conducted from January 2000 to January 2023 using PubMed and Google Scholar for the terms AI and endodontics. Thirty-one studies were evaluated and summarized, highlighting the potential use of different AI models in endodontics. The evaluation of the studies indicated that the use of AI is promising and could aid in tailored endodontics therapy. It would help the clinician in the detection of periapical radiolucency, root fractures, and determination of working length. However, well-designed, high-quality research is required to assess the possible implementation of AI into day-to-day practice in endodontics.
Effect of different intracanal medicaments combined with chitosan nanoparticles on microhardness and fracture resistance of root dentin – An in vitro study
Authors: Halkai Rahul , Halkai Kiran R. , Mahveen Syeda Uzma
Published: May 2024

Introduction:

Chitosan nanoparticles (CSN) are widely used for endodontic disinfection; however, their combination with other intracanal medicaments is least studied; therefore, this study aims to evaluate the effect of various intracanal medicaments incorporated with 0.2% CSN on root dentin microhardness and fracture resistance.

Materials and Methods:

Fifty extracted human single-rooted premolars were cleaned, decoronated, and standardized to 13 mm root length. After access opening and working length determination, specimens were instrumented with ProTaper rotary files till apical size F3 and alternatively irrigated with 5 ml of 2.5% sodium hypochlorite and normal saline (NS). Final irrigation was done with 5 ml of 1% phytic acid. The specimens were allocated randomly into five groups (n = 10), followed by placement of intracanal medicament for 1 week as follows. Group 1 – 0.2% CSN, Group 2 – Calcium hydroxide (Ca[OH] 2) + 0.2% CSN, Group 3 – Triple antibiotic paste (TAP) + 0.2% CSN, Group 4 – Propolis + 0.2% CSN, and Group 5 – Chlorhexidine gluconate (CHX) + 0.2% CSN. The specimens were then rinsed with NS and 3 mm coronal portion of each specimen was horizontally sectioned to create dentin blocks that were further split vertically and tested for Vickers microhardness (n = 10). The remaining root segment of each specimen was then vertically embedded in an acrylic block and evaluated for fracture resistance (n = 10) under a universal testing machine. The data acquired were statistically assessed using one-way ANOVA and posthoc Tukey tests (P < 0.05).

Results:

Propolis incorporated with 0.2% CSN showed the highest microhardness and fracture resistance values followed by CHX + 0.2% CSN, TAP + 0.2% CSN, Ca(OH)2 + 0.2% CSN, and least in 0.2% CSN alone.

Conclusion:

Intracanal medicaments incorporated with 0.2% CSN exhibited a synergetic effect on microhardness and fracture resistance of endodontically treated teeth; however, propolis with 0.2% CSN exhibited higher microhardness and fracture resistance of root dentin.

Authors: Aldandan Ahmed A. , El-Kenawy Mohamed Hassan , Al-Sharif Abdullah A. , Hamam Eman T. , Badr Amany E.
Published: May 2024

Introduction:

The role of Acetyl -11-keto-β-boswellic acid (AKBA) in regulating osteoblast differentiation was recently brought to light. Therefore, the current study was designed to explore the osteogenic differentiation capability of AKBA on bone marrow mesenchymal stem cells (BMMSCs) as a potential therapeutic agent to accelerate the healing process in apicoectomy.

Materials and Methods:

BMMSCs were characterized by flow cytometry. Cellular viability and proliferation assays were used with different concentrations of AKBA. Cells were divided into 5 groups to test osteogenic differentiation: Group I: negative control, Group II: positive control, Group III: BMMSCs were treated with 1 μM AKBA, Group IV: BMMSCs were treated with 0.1 μM AKBA, and Group V: BMMSCs were treated with 0.01 μM AKBA. Mineralization assays and gene expression analysis were assessed, and the significance difference between groups was established at P < 0.05.

Results:

The flow cytometry analysis demonstrated that BMMSCs had positive expression for mesenchymal stem cell marker and negative expression for hematopoietic markers. The concentration of 0.01 μM gave significantly higher cell density than the untreated cells after 7 days (P < 0.05). Cells treated with 0.1 and 0.01 μM AKBA revealed a significantly higher ALP activity, alizarin red, and von Kossa staining than control groups (P < 0.05). High expression of osteogenic genes was detected in BMMSCs treated with 0.1 μM AKBA (P < 0.05).

Conclusions:

It was declared that the concentration of 0.1 μM AKBA has no toxicity on BMMSC viability and proliferation with an impact on BMMSC osteogenic differentiation. Therefore, AKBA (0.01 μM) could be used in bone regeneration during periradicular surgery.
Universality for free fermions and the local Weyl law for semiclassical Schrödinger operators
Authors: Deleporte Alix , Lambert Gaultier
Published: May 2024

We study local asymptotics for the spectral projector associated to a Schrödinger operator

-\hbar^{2}\Delta+V

on

\mathbb{R}^{n}

in the semiclassical limit as

\hbar\to0

. We prove local uniform convergence of the rescaled integral kernel of this projector towards a universal model, inside the classically allowed region as well as on its boundary. This implies universality of microscopic fluctuations for the corresponding free fermions (determinantal) point processes, both in the bulk and around regular boundary points. Our results apply to a general class of smooth potentials in arbitrary dimension

n\ge 1

. These results are complemented by studying both macroscopic and mesoscopic fluctuations of the point process. We obtain tail bounds for macroscopic linear statistics and, provided

n\geq 2

, a central limit theorem for both macroscopic and mesoscopic linear statistics in the bulk.
