Large Fluctuations within 1 au in Protoplanetary Disks
Authors: Chambers John 
Published: April 2024

Abstract
Protoplanetary disks are often assumed to change slowly and smoothly during planet formation. Here, we investigate the time evolution of isolated disks subject to viscosity and a disk wind. The viscosity is assumed to increase rapidly at around 900 K due to thermal ionization of alkali metals, or thermionic and ion emission from dust, and the onset of magnetorotational instability (MRI). The disks generally undergo large, rapid fluctuations for a wide range of time-averaged mass accretion rates. Fluctuations involve coupled waves in temperature and surface density that move radially in either direction through the inner 1.5 au of the disk. Two types of waves are seen with radial speeds of roughly 50 and 1000 cm s−1, respectively. The pattern of waves repeats with a period of roughly 10,000 yr that depends weakly on the average mass accretion rate. Viscous transport due to MRI is confined to the inner disk. This region is resupplied by mass flux from the outer disk driven by the disk wind. Interior to 1 au, the temperature and surface density can vary by a factor of 2–10 on timescales of years to kiloyears. The stellar mass accretion rate varies by 3 orders of magnitude on a similar timescale. This behavior lasts for at least 1 Myr for initial disks comparable to the minimum-mass solar nebula.

Abstract
The study of temperate sub-Neptunes is the new frontier in exoplanetary science. A major development in the past year has been the first detection of carbon-bearing molecules in the atmosphere of a temperate sub-Neptune, K2-18 b, a possible Hycean world, with the James Webb Space Telescope (JWST). The JWST is poised to characterize the atmospheres of several other such planets, with important implications for planetary processes in the temperate regime. Meanwhile, ground-based high-resolution spectroscopy has been highly successful in detecting chemical signatures of giant exoplanets, though low-mass planets have remained elusive. In the present work, we report the atmospheric reconnaissance of a temperate sub-Neptune, TOI-732 c, using ground-based high-resolution transmission spectroscopy. The long orbital period and the low systemic velocity result in a low planetary radial velocity during transit, making this system a valuable test bed for high-resolution spectroscopy of temperate sub-Neptunes. We observe high-resolution time-series spectroscopy in the H and K bands during the planetary transit with the IGRINS instrument (R ∼ 45,000) on Gemini-South. Using observations from a single transit, we find marginal evidence (2.2σ) for the presence of methane (CH4) in the atmosphere and no evidence for ammonia (NH3) despite its strong detectability for a cloud-free H2-rich atmosphere. We assess our findings using injection tests with different atmospheric scenarios and find them to be consistent with a high CH4/NH3 ratio and/or the presence of high-altitude clouds. Our results demonstrate the capability of Gemini-S/IGRINS for atmospheric characterization of temperate sub-Neptunes and the complementarity between space- and ground-based facilities in this planetary regime.

Authors: Zhou Ai-Ying 
Published: April 2024

Abstract
Gaia DR3 revealed 748,058 pulsating variable stars of mixed DSCT∣GDOR∣SXPHE types. This project undertakes a comprehensive examination to validate and distinguish these stars using Transiting Exoplanet Survey Satellite data. Aiming for reliable catalogs of bona fide δ Scuti and γ Doradus stars, I have validated 1715 δ Scuti stars, 1403 γ Doradus stars, and identified 260 eclipsing binaries, one RR Lyrae star, and 460+ rotating variables from an initial sample of 16,690 objects. Notably, 15 of the newfound eclipsing binaries harbor pulsating γ Doradus components.

chez la plupart des patients que nous recevons à Bangui, l’expression des symptômes de plusieurs troubles mentaux est fréquemment centrée sur le corps qui est surinvesti. Cela allonge et complexifie le parcours des soins et retarde la thérapeutique appropriée. Aux fins de dégager l’intérêt des soins précoces en psychiatrie et de montrer la nécessité de former en nombre suffisant les ressources humaines en santé mentale en Centrafrique, nous avons décrit l’itinéraire thérapeutique d’une adolescente de 14 ans, qui a souffert d’une affection mentale ayant un masque somatique. Après avoir parcouru presque tous les spécialistes de la capitale, Emmanuela et sa tante ont consulté en psychiatrie plusieurs mois après le début des premiers symptômes. Le diagnostic posé était le trouble conversif associé à un état dépressif d’intensité moyenne. Emmanuela a bénéficié pendant 04 ans de la psychothérapie d’inspiration psychanalytique et d’un suivi psychiatrique régulier. Elle se porte bien.
Du désir et des vœux
Authors: Aparicio Sol 
Published: April 2024

Le propre de ce que Lacan a dénommé « le champ freudien de l’expérience » est d’être orienté par le désir. Encore faut-il s’entendre sur ce que ce terme usuel veut dire quand c’est de la pratique et de la théorie psychanalytiques qu’il s’agit. C’est ce que Lacan n’a cessé de préciser en lisant et en traduisant Freud. Pour enfin souligner les désaccords entre les langues allemande et française et mieux dire ainsi ce qu’il en est du désir, compte tenu du champ des jouissances, dans le discours analytique proprement dit.
La topologie du désir
Authors: Staricky Annie 
Published: April 2024

Le désir est d’abord le désir de l’Autre, à partir duquel le sujet constitue son propre désir par une torsion. En 1964, dans Les quatre concepts fondamentaux de la psychanalyse , Lacan identifie cette torsion au recouvrement de deux manques : c’est avec son manque-à-être (aliénation) que le sujet se fait disparaître au lieu de l’Autre (séparation) pour poser la question de son désir, Che Vuoi ? Dans la cure, cette torsion se produit de la chute du sujet supposé savoir, où le sujet se destitue et rencontre l’objet a , cause du désir. En 1965, dans Les problèmes cruciaux , Lacan fait de cette torsion « une clé pour la topologie du désir. »
« Désir encore en morceaux »

Le suivi clinique d’un petit garçon de 2 ans, qui au départ, ne reconnaît pas son image dans le miroir. Il s’agira de montrer la manière particulière dont l’objet oral s’attache à la représentation d’unité du corps dans le miroir, et relève de ce que Lacan déplie du stade spéculaire : « Avant que le désir n’apprenne à se reconnaître […] par le symbole, il n’est vu que dans l’autre » et est « […] un désir encore en morceaux ».
L’amour, ignorance du désir
Authors: Hatat Brigitte 
Published: April 2024

L’amour n’est-il que trompeur, masquant l’amour de soi derrière l’amour d’autrui, et la recherche de son propre bien sous couvert du bien de l’autre ? N’y a-t-il pas un vrai amour, un amour désintéressé qui ne serait pas d’essence narcissique et qui prendrait en compte la singularité de l’autre ? La psychanalyse ne promet-elle donc que le rabaissement, voire le ravalement de l’amour ?
La contribution de l’université à l’expérience synodale
Authors: Danto Ludovic 
Published: April 2024

La réflexion synodale offre l’opportunité d’explorer des institutions ecclésiales à partir de ce prisme. Il en est ainsi de l’université. Abordée dans les documents préparatoires du point de vue de la seule gouvernance, l’université en tant que lieu synodal peut être travaillée à partir de ce qu’elle est en tant que telle : un lieu de disputatio où altérité, liberté et égalité promeuvent une méthode propre tant à valoriser dans la suite des droits fondamentaux des fidèles du Christ une participation de l’universitaire au discernement ecclésial qu’à revaloriser le magistère universitaire des docteurs au service de la communauté croyante et du magistère ecclésiastique.
Les pierres d’attente. Les ruines des églises monastiques médiévales, témoins de la promesse
Authors: Brandys Aleksandra 
Published: April 2024

Les paysages du Vieux Continent sont parsemés de ruines des abbayes médiévales, témoins de l’histoire séculaire, de leur patiente construction, de leurs destructions successives et reconstructions. D’abord objet de l’inspiration des peintres et des poètes, les ruines sont aujourd’hui considérées comme une partie intégrante du patrimoine et préservées dans l’état dans lequel leur histoire mouvementée les a laissées. L’expérience d’une église en ruines fait penser à la phrase de l’évangile de Luc : « Je vous le dis, si eux se taisent, les pierres crieront » (Lc 19,40). De la contemplation de ces débris de l’architecture naît une question : que crient ces pierres, qu’attendent-elles ? Quelle est la place des ruines dans l’histoire de l’Église ? Peuvent-elles être un signe paradoxal d’une attente eschatologique ?
Dynamic Changes in Lymphocyte Populations Establish Zebrafish as a Thymic Involution Model

Published: April 2024

Abstract
The thymus is the site of T lymphocyte development and T cell education to recognize foreign, but not self, Ags. B cells also reside and develop in the thymus, although their functions are less clear. During “thymic involution,” a process of lymphoid atrophy and adipose replacement linked to sexual maturation, thymocytes decline. However, thymic B cells decrease far less than T cells, such that B cells comprise ∼1% of human neonatal thymocytes but up to ∼10% in adults. All jawed vertebrates possess a thymus, and we and others have shown zebrafish (Danio rerio) also have thymic B cells. In this article, we investigated the precise identities of zebrafish thymic T and B cells and how they change with involution. We assessed the timing and specific details of zebrafish thymic involution using multiple lymphocyte-specific, fluorophore-labeled transgenic lines, quantifying the changes in thymic T- and B-lymphocytes pre- versus postinvolution. Our results prove that, as in humans, zebrafish thymic B cells increase relative to T cells postinvolution. We also performed RNA sequencing on D. rerio thymic and marrow lymphocytes of four novel double-transgenic lines, identifying distinct populations of immature T and B cells. Collectively, this is, to our knowledge, the first comprehensive analysis of zebrafish thymic involution, demonstrating its similarity to human involution and establishing the highly genetically manipulatable zebrafish model as a template for involution studies.

Authors: Panattil Shaju Padman , Muralidharan Priya , Fernandez Cornelius , Panduranga Prashanth 
Published: April 2024

Abstract
Deep vein thrombosis is commonly associated with pulmonary embolism (PE). However, gluteal vein thrombosis associated with PE is not widely reported. A 39-year-old female complaining of shortness of breath and menorrhagia was evaluated by the gynecologist. Magnetic resonance imaging evaluation of her abdomen and pelvis revealed a left superior gluteal vein thrombus. In view of the patient’s dyspnea and elevated D-dimer, the patient underwent computed tomography pulmonary angiogram, which showed the presence of bilateral PE. The patient’s symptoms improved after anticoagulation with rivaroxaban. This case report highlights the association of gluteal vein thrombosis with PE.
Recurrent First-trimester Cystic Hygroma with Normal Chromosomes Identified in Two Cases with a Recessive Genetic Syndrome
Authors: Zhen Li , Li Dong-Zhi 
Published: April 2024

Abstract
First-trimester cystic hygroma (CH) was a frequent finding in a general obstetric screening program for fetal aneuploidy. Chromosomal abnormalities can be diagnosed in most cases with CH, especially common trisomies and Turner syndrome. For first-trimester CH with a normal array result, management choices are limited except for waiting for serial ultrasounds to detect structural anomalies. We report two cases with a recurrent diagnosis of fetal first-trimester CH in two subsequent pregnancies. In both cases, detailed anatomic surveys in the second trimester showed structural anomalies. After excluding chromosomal abnormalities, trio-exome sequencing (ES) revealed two pathogenic variants, P3H1:c.1032T >A and c.1927_1930delinsGCTT in Case 1, and two pathogenic variants, KIAA1109:c.5788del and c. 3055C >T in Case 2. These findings were associated with two recessive genetic syndromes, osteogenesis imperfecta type VIII and Alkuraya-Kucinskas syndrome, in the two cases, respectively. Our study showed that the recurrence of fetal CH with a normal karyotype strongly indicates the existence of an autosomal recessive type of genetic disorder. For such cases, health providers should be alerted to this possibility, and early application of ES should be considered before the presentation of fetal structural anomalies which are usually present in second-trimester anatomic scans.
Application of CytoPath®Easy Vials in Cervical Cancer Screening: Self-Sampling Approach
Authors: Fernandes Sílvia P. M. , Vilarinho Ana Sofia , Frutuoso Amaro , Teixeira Cidália , Silva Regina Augusta A. P. 
Published: April 2024

Context:

CytoPath®Easy kit (DiaPath S.p.A.) offers a major advantage compared to other commercially available kits available for the screening of cervical cancer, as it does not require additional equipment for sample processing. Using this methodology, collected epithelial cells are immersed in a preservative liquid before setting as a thin layer on a slide via gravity sedimentation.

Aims:
To evaluate the suitability of the CytoPath®Easy kit for the processing of cervical samples, detection of pre-neoplastic lesions, and nucleic preservation and extraction for HR-HPV diagnosis.

Materials and Methods:
A total of 242 self-sampled cervical specimens were utilized, with 192 collected in CytoPath®Easy vials and 50 collected and processed using the ThinPrep
TM for comparative analysis. The samples underwent processing, Papanicolaou staining, and microscopic evaluation for morphological parameters. The extracted nucleic acids were assessed for purity and integrity, and the detection of high-risk human papillomavirus (HR-HPV) was carried out using the Alinitym HR HPV system kit (Abbott Laboratórios Lda).

Results:
Both methods demonstrated effective performance, enabling the morphological assessment of the cervical epithelium. Statistical analysis indicated that ThinPrep
TM yielded significantly better results in terms of cellularity. Conversely, CytoPath®Easy exhibited superior performance in terms of the quantity of extracted DNA and its degree of purification. Concerning the time consumed during processing, both methods were comparable, with the CytoPath®Easy methodology standing out for its cost-effectiveness, as it does not necessitate additional instruments and consumables.

Conclusions:
The novel CytoPath®Easy methodology proves effective in preserving both nucleic acids and cell morphology characteristics, two crucial features for cervical cancer screening.

Published: April 2024

Background and Objective:
In endometrial cytology, differentiating endometrial glandular stromal breakdown (EGBD) from endometrial endometrioid carcinoma (G1-EEC) is often difficult. In this study, we provided a new focus on chondroitin sulfate (CS), a major substrate component of the endometrial stroma, and assessed the diagnostic utility of Alcian Blue (AB) staining in the differential diagnosis in liquid-based cytological (LBC) samples.

Materials and Methods:
LBC specimens from 19 patients with a proliferative endometrium, 36 with EGBD, and 30 with G1-EEC who underwent endometrial cytology were stained with AB (pH 1.0), and their reactivity was observed. In addition, immunocytochemical staining of CS and CD31 was performed for five cases each to evaluate their interrelationship with blood vessels.

Results:
Regarding the 30 G1-EEC cases, at least one of the three representative staining patterns was observed by AB staining: dot-like, microtubular, and finely branched linear patterns. Moreover, the inner portion of the tubular material observed by AB staining expressed CD31. Conversely, in the 36 EGBD cases, only five metaplastic clusters with irregular protrusions and condensed stromal clusters (CSCs) showed a dot-like positive pattern, and background CSCs did not show reactivity to AB staining in any of the cases. Furthermore, the vascular structure expressing CD31 in cell clusters was also unclear.

Conclusions:
We demonstrated that AB staining shows different staining patterns in G1-EEC and EGBD, reflecting their different tissue structures. Our data provide new insights into endometrial cell diagnosis changes and demonstrate that AB staining is a potential new diagnostic aid tool for the differentiation of G1-EEC from EGBD.
Reporting Pancreatic FNAC using the Papanicolaou System: Still a Diagnostic Challenge
Authors: Verma Parul , Goyal Saloni , Tyagi Ruchita , Ghuman Mehar , Mahajan Ramit , Selhi Arshneet Kaur , Kaur Harpreet , Selhi Pavneet Kaur 
Published: April 2024

Introduction:
The Papanicolaou Society of Cytopathology System for reporting Pancreaticobiliary Cytology (PSCPC) is a reliable method to classify pancreatic fine needle aspiration cytology (FNAC) smears. However, it is not without practical problems which can diminish the diagnostic accuracy of the cytological diagnosis.

Aims and Objectives:
To determine the diagnostic pitfalls while reporting cytomorphology of pancreatic lesions according to PSCPC on correlating FNAC findings with histopathology.

Materials and Methods:
Retrospective analysis of pancreatic FNAC smears received in the Department of Pathology of our tertiary care institute over a period of 2 years was done. The cytological diagnoses were classified according to the Papanicolaou Society of Cytopathology system of reporting pancreaticobiliary cytology and correlated with histopathology. The reasons of cyto-histological discordance were analyzed.

Results:
Out of 50 cases in which both FNAC and biopsy of pancreatic lesions were done, 34 cases were positive/malignant (Category VI), eight cases were suspicious for malignancy (Category V), three cases were neoplastic (Category IV), two cases were atypical (Category III), two cases were negative for malignancy (Category II), and one case was non-diagnostic (Category I). Out of 50 cases, histopathology was non-diagnostic due to inadequate material in six cases. The cytological diagnoses were compared with histopathology in the remaining 44 cases. Categories III, IV V, and VI were considered as positive for neoplastic pathology. The sensitivity of FNAC to predict neoplastic pathology was 97.5%, while the specificity was 25%. The positive predictive value was 92.9%. Two cases reported as atypical (Category III) turned out to be adenocarcinoma on histopathology. One case reported as neuroendocrine tumor and two cases reported as adenocarcinoma on cytology displayed features of chronic pancreatitis on histology. One case reported as neoplastic mucinous cyst (Category IV) turned out to be adenocarcinoma on histology (limited concordance).

Conclusion:
The cytopathologist needs to be wary of the potential pitfalls to improve the diagnostic accuracy of FNACs.
Pseudoaneurysm formation following transarterial embolization of traumatic carotid-cavernous fistula with detachable balloon: An institutional cohort long-term study

Published: April 2024

BACKGROUND
The goal of therapy for traumatic carotid-cavernous fistula (TCCF) is the elimination of fistula while maintaining patency of the parent artery. The treatment for TCCF has evolved from surgery to endovascular management using detachable balloons, coils, liquid embolic agents, covered stents, or flow-diverter stent through arterial or venous approaches. Despite the withdrawal of detachable balloons from the market in the United States since 2004, transarterial embolization with detachable balloons has currently remained the best initial treatment for TCCF in several countries. However, the pseudoaneurysm formation following transarterial detachable balloon embolization has rarely been observed in long-term follow-up.
AIM
To determine the occurrence and long-term follow-up of pseudoaneurysm after transarterial detachable balloon for TCCF.
METHODS
Between January 2009 and December 2019, 79 patients diagnosed with TCCF were treated using detachable latex balloons (GOLDBAL) of four sizes. Pseudoaneurysm sizes were stratified into five grades for analysis. Initial and follow-up assessments involved computed tomography angiography at 1 month, 6 month, 1 year, and longer intervals for significant cases. Clinical follow-ups occurred semi-annually for 2 years, then annually. Factors analyzed included sex, age, fistula size and location, and balloon size.
RESULTS
In our cohort of 79 patients treated for TCCF, pseudoaneurysms formed in 67.1%, with classifications ranging from grade 0 to grade 3; no grade 4 or giant pseudoaneurysms were observed. The majority of pseudoaneurysms did not progress in size, and some regressed spontaneously. Calcifications developed in most large pseudoaneurysms over 5-10 years. Parent artery occlusion occurred in 7.6% and recurrent fistulas in 16.5%. The primary risk factors for pseudoaneurysm formation were identified as the use of specific balloon sizes, with balloon SP and No. 6 significantly associated with its occurrence (P = 0.005 and P = 0.002, respectively), whereas sex, age, fistula size, location, and the number of balloons used were not significant predictors.
CONCLUSION
Pseudoaneurysm formation following detachable balloon embolization for TCCF is common, primarily influenced by the size of the balloon used. Despite this, all patients with pseudoaneurysms remained asymptomatic during long-term follow-up.
