Published: February 2025

Abstract
We have detected the 10 μm silicate feature and the 11.3 μm crystalline forsterite feature in absorption in 21 oxygen-rich asymptotic giant branch stars in the Galactic bulge. The depths of the 10 μm feature indicate highly obscured circumstellar environments. The additional crystalline features may suggest either an extended envelope or dust formation in a high-density environment. We have also modeled the spectral energy distributions (SEDs) of the sample using radiative transfer models, and compared the results to wind speeds measured using 1612 MHz circumstellar OH masers, as well as previous estimates of circumstellar properties. The 16 sources with measured pulsation periods appear on sequence D of the mid-IR period–luminosity relation, associated with the long secondary period. We suspect that all of these sources are in fact fundamental-mode pulsators. At least two sources appear on the fundamental-mode sequence when accounting for the dust content. For the remainder, these sources are also likely fundamental-mode pulsators with extended envelopes. Taken as a whole, the high optical depths, crystalline features, discrepancies between observed and modeled wind speeds, pulsation periods longer than other fundamental-mode pulsators, and SED and pulsation properties similar to those with known equatorially enhanced circumstellar envelopes (e.g., OH 26.5+0.6 and OH 30.1–0.7) lead us to believe that these sources are likely to be equatorially enhanced.
Magnetized Protoplanetary Disks around Young Stars in the Presence of Realistic Cooling
Authors: Ghanbarnejad Hanifeh , Ghasemnezhad Maryam 
Published: February 2025

Abstract
In this paper, we study the effects of magnetic fields and ohmic resistivity on the structure of protoplanetary disks (PPDs) in the presence of realistic radiative cooling. We use the self-similar method to solve the magnetohydrodynamic equations in spherical coordinates (r, θ, ϕ). Our solutions indicate that a strong magnetic field reduces the outflow region while increasing the mass accretion rate, which in turn leads to a thicker disk. Our model applied to the FU Orionis PPD indicates that in the inner regions of the disk (r = 10 au),

, which is consistent with the observed range of accretion rates. Additionally, we calculated the cooling timescale in our model to assess one possible fragmentation condition necessary for planet formation. Our results indicate that, although the gravitational instability condition exists in the midplane of the disk, the cooling timescale is not short enough (τ
cool ≈ 1000Ω−1), and one possible mechanism for planet formation is not met.

Effect of Asymmetric Corneal Curvature on Optical Zone Decentration and Refractive Outcomes in SMILE for Myopic Astigmatism
Authors: Fu Xinyi , Zhao Xiaoyan , Gao Guohong , Yu Zhilong , Wang Feng , Li Shuxin 
Published: February 2025

Purpose
To investigate the effect of asymmetric corneal curvature on refractive outcomes and optical zone decentration at a 2-year follow-up after small incision lenticule extraction (SMILE) for myopic astigmatism.

Methods
In this prospective study, 96 patients (169 eyes) with myopia and astigmatism (low astigmatism group [cylinder < −2.00 diopters (D)], 91 eyes; high astigmatism group [cylinder ⩾ −2.00 D], 78 eyes) were treated using SMILE. Two-year postoperative refractive outcomes and optical zone decentration were analyzed and compared between the groups.

Results

Both groups achieved good visual and refractive outcomes. The mean postoperative cylinder in the low astigmatism group was significantly lower than that in the high astigmatism group (
P
< .05). The mean decentration in the low astigmatism group was lower than that in the high astigmatism group (
P
< .05). In the low astigmatism group, a weak positive correlation was observed between target induced astigmatism (TIA) and the arithmetic mean of angle of error (|AE|), difference vector (DV), and the arithmetic mean of magnitude of error (|ME|). Additionally, a weak positive correlation was observed between decentration and both the arithmetic mean of corneal front surface curvature asymmetry indices (|Sif|) and TIA. Within the high astigmatism group, TIA exhibited a weak positive correlation with |AE|, DV, and |ME|. Similarly, decentration demonstrated a weak positive correlation with |Sif|, TIA, DV, and |ME| (all
P
< .05).

Conclusions
SMILE surgery achieves good long-term refractive outcomes for correcting myopic astigmatism. However, there are still limitations to the accuracy of high astigmatism correction. Asymmetric corneal surface curvature may affect the astigmatism correction and optical zone decentration.

Un narcissisme de la différence
Authors: Roy Philippe 
Published: February 2025

Cet article se propose d’exposer la conception du narcissisme de Gilles Deleuze. Au narcissisme du « même », qu’est l’amour de soi-même, duquel Freud reste tributaire, Deleuze entend opposer un narcissisme de la différence qui participe à la constitution du moi (et à sa dissolution...). Il trouve sa raison d’être dans les répétitions-synthèses temporelles de Différence et répétition dont se réclament les synthèses de l’inconscient. S’appuyant pourtant sur le narcissisme freudien, Deleuze s’en écarte sur certains points à cause d’enjeux principaux de sa philosophie. Surtout, le narcissisme deleuzien n’est pas seulement individuel mais ontologique (narcissisme du Temps). Il renoue avec une orientation que le freudisme et plus généralement la psychiatrie ont recouvert.
Leucine-rich alpha-2 glycoprotein as a superior biomarker to C-reactive protein for detecting small bowel lesions in Crohn’s disease
Authors: Ohno Masashi , Nishida Atsushi , Otsuki Akinori , Yokota Yoshihiro , Imai Takayuki , Bamba Shigeki , Inatomi Osamu 
Published: February 2025

BACKGROUND
Achievement of endoscopic healing (EH) is significant in the clinical practice of inflammatory bowel disease as it is correlated with improved prognosis. Existing biomarkers, including C-reactive protein (CRP), have relatively low accuracy for predicting EH, especially in small intestinal lesions in Crohn’s disease (CD); thus, noninvasive and more accurate biomarkers are required. Leucine-rich alpha-2 glycoprotein (LRG), a 50-kD protein, is produced under inflammatory conditions and has been reported to be useful in assessing disease activity in inflammatory bowel disease. However, the usefulness of LRG in small intestinal lesions in CD remains inconclusive.
AIM
To determine the usefulness of LRG for EH in small bowel lesions in CD and compare it with CRP.
METHODS
This study included 133 consecutive patients with CD who underwent balloon-assisted enteroscopy between June 2021 and March 2024 at Shiga University of Medical Science Hospital (Otsu, Japan). We retrospectively analyzed endoscopic scores in each of the ileum and colon and four markers including LRG, CRP, albumin, and Harvey-Bradshaw index (HBI). Spearman’s rank correlation coefficient and receiver operating characteristic analysis were performed.
RESULTS
Either active ileal or colonic lesions exhibited significant differences in LRG, CRP, albumin, and HBI compared with EH. CRP, albumin, and HBI showed a worse correlation with endoscopic activity in the ileum than that in the colon; however, LRG did not show a worse correlation (colon, r = 0.5218; ileum, r = 0.5602). Receiver operating characteristic analysis revealed that LRG for EH in the ileum and colon had the same cutoff values of 12.4 μg/mL. Comparing the areas under the curve of LRG and CRP for predicting EH in the ileum revealed a significantly higher areas under the curve of LRG (95% confidence interval, 0.017-0.194; P = 0.024), whereas the two showed no significant difference in the colon.
CONCLUSION
LRG is a useful biomarker in assessing the endoscopic activity of CD and is more useful than CRP in the small intestine.
Discordance between endoscopic and histopathologic assessment in ileal Crohn’s disease
Authors: Lee Scott D , Mau Brian , Avalos Cody J , Clark-Snustad Kindra D , Kamp Kendra J , Gui Xianyong 
Published: February 2025

BACKGROUND
Discordance between endoscopic and histologic assessments in Crohn’s disease (CD) have been observed, however the prevalence and cause are unclear.
AIM
To assess if a protocolized approach to biopsy collection facilitates understanding of this discordance in patients with ileal CD.
METHODS
Patients with known ileal CD underwent colonoscopy with endoscopic disease activity assessment. Three protocolized biopsies were taken respectively from an ulcer edge, 7-mm, and 14-mm away from the ulcer edge in patients with discrete ileal ulcer(s). In patients with no ulcers as controls, the same 3-site biopsy protocol was applied in a randomly selected area of endoscopically-unremarkable terminal ileal mucosa. A blinded pathologist assessed mucosal inflammation in each biopsy using 3 validated histologic indices.
RESULTS
Twenty-four participants had visible ulcer(s) on endoscopy and 12 served as no-ulcer controls. Of biopsies taken from an ulcer edge, only 67% showed histologic evidence of active (neutrophilic) inflammation, and 33% showed histologic features of ulcer or erosion; all were from either large (n = 4) or very large (n = 4) ulcers. In the no-ulcer controls, no biopsies showed histologic features of ulcer or erosion, but 8% showed active inflammation.
CONCLUSION
A striking discordance exists between endoscopic and histologic assessments for mucosal inflammation in patients with active ileal CD, even in biopsies targeted at an ulcer edge, while a higher concordance is seen in patients with no endoscopic disease activity. It remains unclear how to incorporate histologic disease activity into the treatment paradigm. Further research is needed to optimize biopsy protocols and histologic assessments for CD.
Endoscopic full-thickness resection of rectal schwannoma: A case report
Authors: Zhang Ying-Jie , Yuan Meng-Xia , Wen Wu , Jian Yi , Zhang Chuan-Ming , Yuan Jing , He Lin 
Published: February 2025

BACKGROUND
Rectal schwannoma (RS) is a rare subtype of schwannoma that presents diagnostic challenges owing to its clinical rarity. The absence of typical symptoms, specific signs, and distinctive radiographic findings often hinders clinicians from reaching a definitive diagnosis before surgical intervention. Herein, we report a case of RS who underwent complete resection through endoscopic full-thickness resection (EFTR) and discuss the clinical, imaging, and pathological features for differential diagnosis.
CASE SUMMARY
A 71-year-old Chinese woman presented to our outpatient clinic with a 4-year history of a rectal mucosal mass for a follow-up surveillance colonoscopy. A neurogenic tumor with extraluminal growth was considered based on the imaging findings. Resection was required, and an EFTR was performed. On endoscopic exploration, a smooth surface extruding mass was identified at the rectum. The patient was discharged 48 hours after the operation without infection or bleeding. Based on the pathological and immunohistochemical findings of the resected mass, a rectal benign schwannoma was diagnosed. The patient did not undergo any adjuvant therapy. Nearly one year later, a follow-up surveillance colonoscopy and an abdominal and pelvic plain plus enhancement scan were performed, and no tumor recurrence or metastasis was noted.
CONCLUSION
EFTR is safe and effective for resecting gastrointestinal stromal tumors, especially those with extraluminal growth and no lymph node involvement.
Endoscopic removal of an embedded chicken bone in the esophagus: A case report
Authors: Luo Qi , Tang Lin , Ye Lian-Song , Jiang Zhi-Jie , Mou Yi , Hu Bing 
Published: February 2025

BACKGROUND
Sharp foreign body ingestion can cause gastrointestinal tract mucosa injury and requires proper endoscopic removal. Typically, protective devices are used to reduce mucosal damage. This case presents an alternative approach for the endoscopic removal of a large, irregular, and sharp foreign body (chicken bone) when traditional protective devices are inadequate, thus contributing to the management of such ingestions.
CASE SUMMARY
A 57-year-old male presented with a history of swallowing an irregular and sharp-pointed chicken bone. Emergent endoscopy showed it was tightly embedded in the esophageal wall, with minor bleeding. The chicken bone was grasped and moved cautiously using a foreign forceps. It was loosened after repeated attempts but could not pass through the pharynx. Considering possible mucosal damage, it was carefully pushed into the stomach cavity and then wrapped in a condom. The chicken bone was retrieved uneventfully by grasping the open edge of the condom with foreign forceps. No additional damage was found, except for primary esophageal injuries caused by the embedded chicken bone. The patient was discharged on the following day. Our experience demonstrated that condoms can be an alternative as a protective device under such conditions.
CONCLUSION
Condoms can serve as an alternative when traditional protective devices are unsuitable. Because of its smooth and oily nature, it can provide mucosal protection and lubrication during endoscopic removal.
The Digital Leadership Differences Between Primary and Secondary Teachers for Empowering Sustainable Development Goal (SDG) in Education Using Situational Judgement Test (SJT)
Authors: Musid Nurhafizah Abdul , Matore Mohd Effendi Ewan Mohd , Hamid Aida Hanim A. 
Published: February 2025

Introduction: One of the leadership philosophies that has been getting more and more attention lately is digital leadership. However, measuring the level of digital leadership has not yet been widely discussed. Furthermore, one tool for gathering data is the Situational Judgement Test (SJT). In the recent discussion, the level of digital leadership between primary and secondary teachers has hardly been discussed. Measuring and comparing digital leadership among teachers aligns with the overarching goal of improving education quality, which is a key aspect of Sustainable Development Goal (SDG) 4: Quality Education.

Objective: This study intends to determine whether there are significant differences in nine digital leadership dimensions between primary and secondary teachers utilising the SJT as a data collecting tool.

Method: This study involved 2,830 respondents from Malaysia. The respondents were teachers who were selected using stratified random sampling. All 10 assumptions are met before the one-way MANOVA analysis is conducted.

Results and Discussion: The results indicate that there is no statistically significant difference in the mean score of digital leadership in terms of (1) student engagement, learning and outcomes, (2) learning environment and spaces, (3) professional growth and learning, (4) communication, (5) public relations, (6) branding, (7) opportunities, (8) empowered professionals, and (9) learning catalyst between primary and secondary teachers. Therefore, no further analysis is required.

Research Implications: This study contributes to the measurement aspect by using a different assessment tool to collect data, namely the SJT.

Originality/Value: The study's findings highlight the relationship between the nature of SJT and digital leadership dimensions. Moreover, this study measures the level of digital leadership based on a combination of two sources as a reference for the constructs. Therefore, it is recommended that SJT be used as an assessment tool in future research on various styles of leadership.

Модернизация армянской хореографии через взаимодействие с современной музыкальной культурой
Authors: Чатоджян М.С. 
Published: February 2025

Статья рассматривает процессы модернизации армянской хореографии в контексте ее взаимодействия с современной музыкальной культурой. Цель данного исследования – анализ того, как музыкальные инновации – от электронных жанров до этно-джаза, минимализма – могут способствовать сохранению, преобразованию хореографического наследия Армении, что делает его доступным, привлекательным для широкой аудитории, включая международную. Методологический подход исследования включает анализ конкретных хореографических постановок, в которых прослеживается взаимодействие с новыми музыкальными формами. Также проводится сравнительный анализ традиционных танцевальных элементов. Особое внимание уделяется таким аспектам, как ритмическая структура, полиритмические акценты, использование многослойных звуковых текстур, позволяющие хореографам обогатить выразительный арсенал танца. Результаты исследования показывают, что использование современной музыки способствует внедрению асимметрии, импровизации, вариативных ритмов, что изменяет художественный облик традиционных армянских танцев. Синтез музыки, движения создает возможность для креативного переосмысления культурных образов, символов, что, в свою очередь, актуализирует армянскую хореографию в глобальном контексте.
The article examines the processes of modernization of Armenian choreography in the context of its interaction with modern musical culture. The purpose of this study is to analyze how musical innovations – from electronic genres to ethno–jazz, minimalism – can contribute to the preservation and transformation of Armenia’s choreographic heritage, which makes it accessible and attractive to a wide audience, including international ones. The methodological approach of the research includes the analysis of specific choreographic productions in which interaction with new musical forms is traced. A comparative analysis of traditional dance elements such as “Kochari”, “Yarkhushta” and their modern interpretations is also carried out. Special attention is paid to such aspects as rhythmic structure, polyrhythmic accents, and the use of multi-layered sound textures, which allow choreographers to enrich the expressive arsenal of dance. The results of the study show that the use of modern music contributes to the introduction of asymmetry, improvisation, and variable rhythms, which changes the artistic appearance of traditional Armenian dances. The synthesis of music and movement creates an opportunity for creative reinterpretation of cultural images and symbols, which, in turn, actualizes Armenian choreography in a global context.
