Abstract
LT Eri is a long-period eclipsing cataclysmic variable star (CV). This study investigates its outbursts, negative superhumps (NSHs), tilted-disk precession, eclipse-depth variations, and observed minus calculated (O – C) behavior, using photometric data from the Transiting Exoplanet Survey Satellite (TESS), the Zwicky Transient Facility, the All-Sky Automated Survey for Supernovae, and the American Association of Variable Star Observers. Our analysis reveals an outburst period of 14.7(31) days, with variable periods ranging from 11.62(4) to 22.15(13) days. Both long and short outbursts were detected, lasting approximately 18 and 10 days, respectively. Analysis of the TESS photometry shows that the NSH period is updated to 0.16265161(7) days, persists during the outburst, and its amplitude is correlated with the outburst phase. A suspected signal of tilted-disk precession with a period of 3.5781(6) days is also detected. Additionally, the eclipse depth shows a periodic variation of 3.6270(9) days, closely matching the tilted-disk precession period; however, no biperiodic variation is found, as seen in the dwarf nova HS 2325+8205, suggesting that this phenomenon is not universal. An O – C analysis reveals a weak oscillation with a period of 3.5772(6) days. Our superposition of sine curves consistent with the NSH period and amplitude, along with mean eclipse curves, produces periodic O – C variations with a period of 3.6666(2) days. This indicates that the observed periodic variations in O – C, often around the disk precession period in CVs, may result from the beat between the NSHs and the eclipse rather than actual variations in the accretion disk.

Abstract
Recent results from numerical simulations and models of galaxy formation suggest that recently discovered ultrafaint compact stellar systems (UFCSs) in the halo of the Milky Way (MW) may be some of the smallest and faintest galaxies. If this is the case, these systems would be attractive targets for indirect searches of weakly interacting massive particle dark matter (DM) annihilation due to their relative proximity and high expected DM content. In this study, we analyze 14.3 yr of γ-ray data collected by the Fermi-Large Area Telescope coincident with 26 UFCSs. No significant excess γ-ray emission is detected, and we present γ-ray flux upper limits for these systems. Assuming that the UFCSs are DM-dominated galaxies consistent with being among the faintest and least massive MW dwarf spheroidal (dSph) satellite galaxies, we derive the projected sensitivity for a DM annihilation signal. We find that observations of UFCSs have the potential to yield some of the most powerful constraints on DM annihilation, with sensitivity comparable to observations of known dSphs and the Galactic center. This result emphasizes the importance of precise kinematic studies of UFCSs to empirically determine their DM content.
Les langues d’Asie, une complexité cachée
Authors: Vittrant Alice 
Published: January 2025

Loin de certaines croyances ayant eu cours dans l’histoire de la
linguistique, il règne actuellement un consensus sur l’égale complexité des
langues indépendamment de leur type morphologique ou de leur affiliation. Dans
un grand nombre de travaux, la complexité d’une langue est évaluée en termes de
nombre et de variété des éléments (morphèmes) constituant l’item langagier. La
complexité grammaticale d’une langue se mesure alors en termes de distinctions
exprimées, généralement de manière obligatoire. Ainsi du point de vue de la
morphologie, on associera complexité avec flexion et caractère obligatoire d’une
expression. Or les langues d’Asie du Sud-est et d’Asie orientale nous racontent
une autre histoire. Elles suggèrent que cette « complexité exprimée » (overt complexity) n’est qu’un type particulier de
complexité, et que le fonctionnement éminemment pragmatique de ces langues
(interprétation basée sur le contexte) cache une complexité d’un autre genre,
une « complexité cachée » (hidden complexity), rarement
décrite qui prend sa source dans la propension des langues d’Asie à dire peu en
laissant deviner beaucoup.
L’institutionnalisation de l’étude du chinois au xixe siècle : au croisement du pouvoir et du savoir
Authors: Zhang-Colin Ying 
Published: January 2025

Cette contribution a pour objet l’organisation de l’étude du chinois en France au xixe siècle. Elle s’appuiera sur la création de chaires de chinois dans deux institutions privilégiées : le Collège de France et l’École spéciale des langues orientales. En questionnant les conditions qui les ont rendues possibles et les caractéristiques des recherches linguistiques en leur sein, nous essayerons d’apporter un éclairage sur les rapports complexes entre le savoir, le pouvoir et l’institution. Au travers du terme de « sinologie », autour duquel les recherches sur la Chine et sur la langue chinoise s’organisèrent, nous réfléchirons également à la notion de discipline scientifique et à son historicité.
Le défaut de « forme interne » dans les langues mandingues selon la psychologie des peuples de Steinthal (1867)
Authors: François Jacques 
Published: January 2025

En 1848, Steinthal a esquissé une vaste entreprise épistémologique fusionnant la vision de Humboldt sur le génie des langues (Sprachgeist) indissociable de l’esprit des peuples qui les parlent (Volksgeist) et celle de Hegel sur la phénoménologie de l’esprit progressant dialectiquement d’âge en âge. En 1867 il met à jour une étude lauréate du Prix Volney afin d’illustrer concrètement sa théorie de la distinction fondamentale entre les langues dotées vs dénuées d’un format morphologique. Le propos de cet article est de montrer en quoi son argumentation dans cette étude est victime de l’obstacle axiologique (cf. François 2014) qui a jeté une ombre sur les prouesses de la linguistique allemande du xixe siècle : il était inconcevable qu’un peuple primitif parle une langue attestant d’un pouvoir d’abstraction et Steinthal trouvait dans les langues des peuples mandingues les preuves de leur inaptitude à toute pensée abstraite.
Wüster et l’aménagement linguistique
Authors: Humbley John 
Published: January 2025

Le rôle de Wüster comme premier théoricien de la terminologie est bien connu mais les relations qu’il a entretenues avec l’aménagement linguistique le sont moins. Sa réflexion était située dans la linguistique appliquée de son époque, car il considérait que la langue, ou du moins la terminologie et la langue de spécialité, étaient un outil qui peut et qui doit être adapté dans le but d’en améliorer l’efficacité. Ce chapitre propose une lecture commentée de ses écrits sur le sujet publiés sur une période de près de 40 ans, qui fait ressortir la cohérence de ses attitudes. Sont mises en exergue ses positions sur la normalisation et le rapprochement international, la synonymie et l’évolution spontanée de la langue, l’acronymie et l’abréviation en général, l’équipement de la langue en particulier sous la forme des dictionnaires et d’autres supports documentaires.
La contribution des Pères blancs de la Société des missionnaires d’Afrique à la connaissance des langues berbères
Authors: Amaoui Mahmoud 
Published: January 2025

Cette réflexion aborde la contribution des Missionnaires d’Afrique (Pères blancs) à l’outillage des langues berbères. Nous nous sommes intéressé tout particulièrement à la période comprise entre 1946 et 1976, qui correspond à l’activité du Centre d’études berbères, créé par cette congrégation religieuse, et à la publication du Fichier de documentation berbère, un périodique qui lui est associé. Pour traiter ce sujet, une description même sommaire de « l’organisation scientifique » des Pères blancs, de leurs méthodes d’investigation et des rapports qu’ils entretenaient avec le monde académique (les linguistes berbérisants et les institutions universitaires notamment) s’est avérée nécessaire.
Les concours académiques de la deuxième moitié du xviiie siècle : une forme historique de production de savoirs linguistiques
Authors: Haßler Gerda 
Published: January 2025

Au xviiie siècle, les académies européennes n’étaient pas seulement des assemblées de philosophes, de gens de lettres et de savants reconnus par leurs pairs qui avaient pour mission de veiller aux règles et aux usages dans leurs disciplines. En ce qui concerne le langage, les académies devaient, bien sûr, s’occuper de la normalisation des langues, mais elles incitaient aussi à la réflexion sur le langage et la littérature et elles contribuaient à fournir des réponses à la discussion linguistique de l’époque. À cet effet, plusieurs académies européennes organisaient des concours dont les sujets étaient les résultats, parfois, d’un long débat à l’intérieur des institutions. Cette époque fut celle de l’apogée des questions de prix des académies.
Suicide, taedium uitae et droit romain sous le Principat
Authors: Waquet François 
Published: January 2025

Le suicide a été diversement considéré chez les Anciens. Pour les Stoïciens, il est la conclusion d’un raisonnement plutôt que le résultat d’une émotion violente. À cet égard, plusieurs études historiques avaient déjà montré les raisons patrimoniales qui présidaient à certains suicides au début de l’Empire romain. Prolongeant cette perspective, mais avec une approche seulement juridique, cet article interroge la catégorie du taedium uitae, « dégoût de la vie », en tant que cause légitime du suicide en droit romain.

Abstract:

BACKGROUND:
Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome (BCR-ABL1 fusion gene). CML primarily progresses through chronic, accelerated, and blast phases. While global studies on BCR-ABL1 fusion transcript types and their associations with clinical, laboratory, and prognostic profiles exist, such data is scarce in Malaysia.

OBJECTIVES:
This study aimed to determine the distribution of BCR-ABL1 fusion transcript types and evaluate their associations with demographic, clinical, laboratory, prognostic profiles, and disease outcomes among Malaysian CML patients.

PATIENTS, MATERIALS AND METHODS:
A total of 98 patients diagnosed with CML were identified at East Coast Hospital, Malaysia. This 12-year cross-sectional study was carried out using data extracted from patients’ medical records. Molecular results for BCR-ABL1 fusion genes were obtained using one-step multiplex reverse transcriptase polymerase chain reaction.

RESULTS:
Out of the 98 patients, 56% had e14a2, 41% had e13a2 fusion transcripts, while the remaining 2 patients had e14a3 transcripts. Additionally, 1 patient co-expressed both e13a2 and e14a2. Among patients with the major BCR-ABL1 transcript type, those with e14a2 fusion transcripts showed an older median age (P = 0.025), while patients with e13a2 fusion transcripts had significantly higher white blood cell (WBC) counts (P = 0.014). Furthermore, there were significantly more patients with blastic transformation in the e13a2 group (P = 0.038). The median latency period of CML was 12 months. The blast cell lineages consisted of myeloid (68.4%), followed by B-lymphoid (26.3%) and mixed phenotypic (5.3%). The differences in fusion transcript expression might influence certain parameters; for instance, older patients were associated with the e14a2 fusion transcript. Meanwhile, patients exhibiting e13a2 might have a higher WBC count at diagnosis and be more vulnerable to blastic transformation of CML.

CONCLUSIONS:
This study highlights the predominance of e14a2 fusion transcripts in Malaysian CML patients and its association with older age. The e13a2 transcript was linked to higher tumor burden and a higher rate of blastic transformation, suggesting potential prognostic significance. These findings underscore the importance of baseline molecular profiling for optimizing disease management.
Comparison between biodentine and light-cured mineral trioxide aggregate as an indirect pulp capping agent – A randomized controlled trial
Authors: Mangat Panna , Goswami Kartika , Solanki Mandeep , Rajput Neha 
Published: January 2025

Abstract

Background:
Indirect pulp capping (IPC) represents a pivotal therapeutic intervention directed toward preservation of pulp vitality, achieved through the placement of a biocompatible, bioactive material over the affected dentin to protect the pulp from further insult and encourage healing.

Aim:
This study aimed to evaluate the clinical and radiographical success rates of Biodentin versus light-cured mineral trioxide aggregate (MTA) when used as an IPC agents. Evaluation was done on the basis of prognosis of the treatment after a period of 1 year.

Methodology:
This randomized controlled clinical trial was based on a cohort of 20 individuals with deep carious lesions being subsequently divided into two experimental groups of ten cases each. Group I - Biodentin and Group II - Light cured-MTA as pulp capping agents, respectively. Clinical and radiographical assessment was done at baseline, 1, 2, 3, 6 months, and 1 year.

Results:
Statistical analysis with the Chi-square test showed no statistically significant difference between the groups. The overall success rate of 1-year follow-up for both Biodentine group and Light-cured MTA group was 93.33%.

Conclusion:
The results of this randomized controlled clinical trial support promising success of IPC independent of the pulp capping material used as the findings underscore a significant decrease in postoperative pain levels compared to preoperative states across all cases. However, more studies with long-term follow-ups are required.

Published: January 2025

Abstract

Aim:
The aim of this study was to assess the cytotoxicity of endodontic irrigants 2% chlorhexidine (CHX) and ethylenediaminetetraacetic acid (EDTA) combined with cationic peptide DJK-5 on L929 mouse subcutaneous fibroblast cells.

Subjects and Methods:
L929 cells were cultured and treated with 2% CHX, 2% CHX + DJK-5, 8.5% EDTA, 8.5% EDTA + DJK-5, and DJK-5 alone (DJK-5 peptide concentration–10 μg/mL) for 24 and 48 h. The cytotoxicity of the endodontic irrigants was determined using methyl thiazolyl tetrazolium assay and Live/Dead assay using acridine orange and ethidium bromide dual fluorescence staining.

Statistical Analysis Used:
The Shapiro–Wilk test was used to verify the normality of the data within each group at two different time points. Parametric tests were used for the comparison. Paired sample t-test was used for the comparison of the cytotoxicity of irrigants over time. One-way ANOVA was employed for the comparison of the cytotoxicity of irrigants. Tukey’s test was used for pairwise comparison between groups. SPSS software version 27 was used for the data analyses.

Results:
CHX exhibited slight cytotoxicity at 24 h and higher cytotoxicity at 48 h (P < 0.05). EDTA showed better cell viability than CHX at both time points. In combination groups, the EDTA + DJK-5 group showed lower cytotoxicity at both time points (P > 0.05). The combination of CHX with DJK-5 reduced the cytotoxicity of CHX (P < 0.05).

Conclusions:
The cytotoxicity of endodontic irrigants was found to be time dependent. CHX was found to be highly cytotoxic at 2% concentration. DJK-5 was found to have the least cytotoxicity, and it significantly reduced the cytotoxicity of CHX and EDTA.
Evaluation of three different drugs administered through intraligamentary route for reduction of intraoperative pain of symptomatic irreversible pulpitis in mandibular molars – A randomized triple-blind single-center clinical study
Authors: Shroff Manan , Kishan Karkala Venkappa , Shah Nimisha , Volety Shreya , Kaur Supreet , Kotecha Niral 
Published: January 2025

Abstract

Introduction:
Managing intraoperative pain while initiating root canal treatment necessitates the use of supplementary injection techniques.

Aim:
The study sought to assess and compare the anesthetic efficacy of 0.5% bupivacaine and 50 mg/ml tramadol hydrochloride versus 2% lignocaine administered as supplemental intraligamentary injection as an adjuvant to an inferior alveolar nerve block (IANB) for mandibular molars with symptomatic irreversible pulpitis (SIP) and normal apical tissues during access cavity preparation.

Materials and Methods:
Two hundred and two individuals with mandibular molars diagnosed with SIP with normal apical tissues and exhibiting moderate-to-intense pain were given 2 ml of IANB containing 2% lignocaine and 1:80,000 epinephrine. The Visual Analog Scale (VAS) was used to record intraoperative discomfort. Individuals who scored more than 5 on the VAS were deemed to need further anesthesia. The intraligamentary medication was given to 99 of these patients after they were randomly assigned to 3 groups (2% lignocaine, 0.5% bupivacaine, and 50 mg/ml tramadol). VAS score was again recorded. If the patient reported no pain during the opening of the access, it was deemed a success. The post hoc Tukey’s test, paired t-test, and one-way analysis of variance were the statistical methods used to examine the data.

Results:
Maximum reduction in pain was in bupivacaine followed by lignocaine and tramadol (P < 0.05). Subgroup analysis using post hoc Tukey’s honestly significant difference test showed a maximum difference between bupivacaine and tramadol (1.273, P > 0.05) (95% confidence interval [CI]), followed by lignocaine and bupivacaine (−1.182, P < 0.05) (95% CI) and lignocaine and tramadol (0.091, P > 0.05) (95% CI).

Conclusion:
Bupivacaine was most effective in reduction of intraoperative pain when used as an intraligamentary drug during access cavity preparation followed by lignocaine. Tramadol was the least successful drug for achieving effective pulpal anesthesia.
To compare and evaluate microcracks and smear layer after root end preparation by laser, ultrasonic tip, and conventional bur in single-rooted teeth: “Scanning electron microscope study”

Published: January 2025

Abstract

Aim:
Evaluation of root-end cavities for the existence of microcracks and smear layer with laser, ultrasonic tip by conventional bur, and control group in single-rooted tooth by scanning electron microscope (SEM).

Methodology:
Fifty-two extracted fully developed single-rooted teeth were decoronated, cleaned, shaped, and obturated with F2 GP, and 3 mm roots were removed. Laser, ultrasonic tip (AS 3Dretro-tip on Newtron-SATELEC, Acteon), and conventional bur (size 010 round) were used to create root-end preparation. No root-end cavities were produced in the control group. SEM was used to check all samples for microcracks and smear layers.

Results:
A significant difference was found between microcrack formation in laser and conventional bur preparation (P = 0.002), and ultrasonic and laser (P = 0.015). Nonsignificant difference was found between ultrasonic and conventional bur (P = 0.046). The study concluded that maximum cracks were seen in conventional bur formation at the apical end of the root (0.85 ± 0.36) followed by the ultrasonic method (0.54 ± 0.23).

Conclusion:
Root-end cavities prepared with laser give fewer microcracks and less production of smear layer compared to the ultrasonic tip and conventional bur.

Authors: Alzahrani Abdullah A. , AlQarni Norah A. , Alghamdi Fahad S. , Alghamdi Tariq A. 
Published: January 2025

ABSTRACT

Introduction:
Family doctors are the primary care providers for ankle sprains, which are a prevalent condition that they treat with great care. Family physicians’ differing management styles and levels of knowledge about established recommendations may have a substantial influence on patient outcomes.

Aims:
The current study aimed to assess the level of awareness among family physicians regarding established guidelines for ankle sprain management.

Materials and Methods:
A cross-sectional study was conducted targeting all available and accessible primary care physicians within the Department of Family Medicine at King Fahad Armed Forces Hospital, Jeddah, Saudi Arabia during the period from 2023 to May 2024. Data were collected using an online questionnaire that was initiated by the study researchers after comprehensive review of similar articles in the literature.

Results:
A total of 88 primary care physicians were included. Physicians’ ages ranged from 25 to 60 years with a mean age of 33.4 ± 7.4 years old. A total of 47 (53.4%) were males, 29 (33%) were residents, 28 (31.8%) were consultants, 16 (18.2%) were senior Registrar, and 9 (10.2%) were GPs. A total of 41 (46.6%) of the study physicians had an overall good knowledge level about ankle sprain while most of them (53.4%) had poor knowledge level. A total of 55 (62.5%) of the study physicians utilize the Ottawa Ankle Rules to guide the need for X-ray imaging in ankle sprains, and 52 (59.1%) routinely provide information on preventive measures to patients diagnosed with an ankle sprain.

Conclusion:
The study found that primary care physicians have average knowledge about ankle sprains, diagnosis, classification, and treatment, with lower knowledge of follow-up plans. They need training and educational programs.
