Published: January 2025

This study highlights the importance of implementing an appropriate learning system to achieve learning objectives, especially in the context of early childhood education post-covid-19. This study aims to determine the implementation and challenges faced by teachers and parents in online learning post-covid-19. Using a descriptive qualitative research method, data collection was carried out through observation, interviews, and Google Forms, and analyzed using the triangulation method. The results showed various challenges such as limited facilities and infrastructure, lack of understanding of teachers and parents, and less than optimal collaboration. In addition, the condition of the child and the limitations of the media used are also obstacles. This study suggests that teachers need to facilitate internet networks and understand the characteristics of effective online learning. The main indicators of successful online learning for early childhood include the presentation of appropriate materials, the use of appropriate methods and media, and clear assessment strategies. This implementation is important to ensure that children still get an optimal learning experience even though it is done online.
Girlhood at the Margins of French Filmmaking: Deniz Gamze Ergüven’s

This article demonstrates how the transnational interactions on- and off-screen in the Franco-Turkish
Mustang
(Deniz Gamze Ergüven, 2015) and the Franco-Kosovar
La Colline où rugissent les lionnes
(Luàna Bajrami, 2022) influence the films’ representation of girlhood. While set beyond France’s borders, the protagonists’ quest for girlhood power or luminosity reveals how these films are influenced by their transnational Frenchness. This article interrogates how the characters’ experience of culturally specific gendered oppression is positioned in opposition to what is constructed as liberated European French girlhood, exemplified by the French republican values of equality, education and mobility. With France thus both the centre and the periphery in these films, this article argues that the films’ transnationality is central to understanding how, caught between the promised luminosity of republican girlhood and their own experiences of girlhood as a site of oppression, the characters are constrained by the margins of identity.

M dwarfs have become increasingly important in the detection of exoplanets and the study of Earth-sized planets and their habitability. However, 20%–30% of M dwarfs have companions that can impact the formation and evolution of planetary systems. We use high-resolution imaging and Gaia astrometry to detect stellar companions around M dwarf exoplanet hosts discovered by TESS and determine the projected separation and estimated stellar masses for each system. We find 47 companions around 216 M dwarfs and a multiplicity rate of 19.4% ± 2.7% that is consistent with field M dwarfs. The binary projected separation distribution is shifted to larger separations, confirming the lack of close binaries hosting transiting exoplanets seen in previous studies. We correct the radii of planets with nearby companions and examine the properties of planets in M dwarf multistar systems. We also note three multiplanet systems that occur in close binaries (≲50 au) where planet formation is expected to be suppressed.

Young supernova remnants (SNRs) are believed to be the origin of energetic cosmic rays (CRs) below the “knee” of their spectrum at ∼3 PeV (1015 eV). Nevertheless, the precise location, duration, and operation of CR acceleration in young SNRs are open questions. Here, we report on multiepoch X-ray observations of Cassiopeia A (Cas A), a 350 yr old SNR, in the 15–50 keV band that probes the most energetic CR electrons. The observed X-ray flux decrease (15% ± 1% over 10 yr), contrary to the expected >90% decrease based on previous radio, X-ray, and gamma-ray observations, provides unambiguous evidence for CR electron acceleration operating in Cas A. A temporal model for the radio and X-ray data accounting for electron cooling and continuous injection finds that the freshly injected electron spectrum is significantly harder (exponential cutoff power-law index q = 2.15), and its cutoff energy is much higher (E
cut = 36 TeV), than the relic electron spectrum (q = 2.44 ± 0.03, E
cut = 4 ± 1 TeV). Both electron spectra are naturally explained by the recently developed modified nonlinear diffusive shock acceleration (mNLDSA) mechanism. The CR protons producing the observed gamma rays are likely accelerated at the same location by the same mechanism as the injected electrons. The Cas A observations and spectral modeling represent the first time radio, X-ray, gamma-ray, and CR spectra have been self-consistently tied to a specific acceleration mechanism—mNLDSA—in a young SNR.

We present a systematic analysis of the velocity structure functions (VSFs) of 167 molecular clouds with angular sizes greater than ~176 arcmin2 in three sectors of the Galactic midplane. We calculated the first-to-third-order VSFs and found that 60% of the VSFs exhibit power-law distributions. The relative power-law exponents are consistent with predictions from intermittent turbulence models. Column density weighting reduces the proportion of power-law VSFs and steepens the VSF slopes, implying a reduction of turbulent energy in high-density regions. All clouds show small-scale intermittency, with slightly stronger intermittency in those molecular clouds showing “none” power-law VSFs. Negative VSF exponents that may indicate gravitational collapse are not observed in our sample. The scaling exponents of the observed VSFs do not correlate with the virial parameters of the molecular clouds. These two observations suggest that gravity-dominated scales in molecular clouds still need further investigation. Consistent VSF scaling exponents for the molecular clouds with significant power-law VSFs suggest large-scale external driving of turbulence in these molecular clouds. However, the driving mechanisms are likely not universal, as the power-law scaling coefficients in our results show relatively large scatter. The fact that nearly 40% of the VSFs deviate to some extent from power-law distributions suggests that the influence of local environments on the internal turbulence of molecular clouds may not be negligible.
Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach
Authors: Hernandez Camero Julio , Green Lucie M. , Piñel Neparidze Alex
Published: January 2025

Identifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph with their source active regions, specifically Space Weather HMI Active Region Patches (SHARPs), between 2010 May and 2019 January. Our method uses posteruptive signatures, including flares and coronal dimmings, to associate CMEs with potential source regions. Out of 4190 CMEs, we successfully match 1132, achieving a recall rate of ~57% for frontside events. We find that the algorithm performs better for complex SHARP regions containing multiple NOAA regions and for faster CMEs, consistent with expectations that more energetic events produce stronger eruption signatures. We find that CME–flare association rates increase with flare intensity, aligning with previous studies. While our approach has limitations, such as focusing exclusively on SHARP regions and relying on a limited set of posteruptive signatures, it significantly reduces the time required for CME source identification while providing transparent, reproducible results. We encourage the solar physics community to build upon this work, developing improved automated tools for CME source identification. The resulting catalog of CME–source region associations is made publicly available, offering a valuable resource for statistical studies and machine learning applications in solar physics and space weather forecasting.
Investigating the Lower Limit of Metallicity for the Galactic Thin Disk

We explore the metal-poor regime of the Galactic disk on the distribution of stars in the [α/M]–V

ϕ
plane, to identify the most metal-poor thin disk (MPTnD) stars belonging to the low-α sequence. Chemical abundances and velocities of sample stars are either taken or derived from APOGEE DR17 and Gaia DR3 catalogs. We find the existence of a well-separated extension of the kinematically thin disk stars in the metallicity range of −1.2 < [M/H] < −0.8 dex. Based on two-by-two distributions of [Mg/Mn], [Al/Fe] and [C+N/Fe], we further confirmed 56 high-possibility metal-poor thin disk (HP-MPTnD) giant stars and suggested the lower metallicity limit of the thin disk below −0.95 dex. A comparative analysis of the HP-MPTnD sample with other Galactic components revealed its chemo-dynamical similarities with canonical thin disk stars. These low-α metal-poor stars are predominantly located in the outer disk region and formed in the early stage of the formation of thin disk. Their existence provides compelling support for the two-infall model of the Milky Way's disk formation. Moreover, these stars impose observational constraints on the timing and metallicity of the second gas infall event.

Published: January 2025

This study presents analyses of the optical variability of the 1ES 1215+303 on diverse timescales using multiband observations, including observations in the optical BVRI bands carried out with the 0.6 and 1.0 m telescopes located at the Tübitak National Observatory (TUG) from 2022 to 2024 and Zwicky Transient Facility (ZTF) gri data from 2018 to 2023. Investigation of variability on intraday timescales revealed amplitudes of 4.0% and 5.6% on two nights, with a calculated duty cycle of 63%. We determined a minimum timescale of ~92 minutes from these observations, leading us to limit the radius for the optical emission region and the mass of the black hole. The blazar exhibits moderate short- and long-term variability, with variability amplitudes reaching up to 120% and decreasing as the wavelength shortens. Correlation analysis revealed a strong correlation between the optical multiband emissions without any time lag. Analysis of 109 nightly spectral energy distributions yielded spectral indices ranging from 0.772 to 1.413. The consistent trend of both spectral indices and color with respect to brightness suggests a mild bluer when brighter trend persists throughout the observation period, in contrast to the intraday timescale. Utilizing the weighted wavelet z-transform and Lomb–Scargle methods, we analyzed recurrent optical emission patterns on the combined R-band light curves from TUG, ZTF, and Tuorla observations, revealing a quasiperiodic signal at around 1000 days and a secondary signal at approximately 300 days. These signals were found to be insignificant after accounting for the stochastic process and the trial factor.
Exploring Spica's Apsidal Motion: Insights from Feature Engineering and Machine Learning with MESA
Authors: Woodruff Hannah C. , Samaraweera Dumindu , Aufdenberg Jason P.
Published: January 2025

Spica (α Virginis), a massive binary star system, offers insights into stellar evolution. Its orbital evolution, governed by the apsidal motion constant, reveals critical details about the stellar interior. However, calculating this constant using Modules for Experiments in Stellar Astrophysics (MESA) simulations is computationally demanding. To address this, we employed machine learning (ML) and deep learning (DL) methods to efficiently predict the apsidal constant. Random Forest and Recursive Neural Network emerged as the most effective ML and DL models, respectively, with luminosity, age, and temperature identified as key features. Our ensemble voting regressor, integrating ML and DL approaches, achieved superior accuracy. MESA models are consistent with recent constraints on Spica A's effective temperature, age, luminosity, and apsidal constant. This work promotes the potential of ML and DL in stellar research, advancing the understanding of the apsidal constant through stellar evolution.
Closed -Form Expressions forPredicting Certain Projectile Trajectories
Authors: Smith Charles
Published: January 2025

Accurate prediction of the trajectory of a projectile passing through air almost always requires the aid of computer-assisted numerical procedures. Herein are derived closed-form expressions for a certain class of such trajectories, which can provide insights not readily obtainable with computer codes alone. For example, the expressions reveal errors in widely-promulgated formulas for predicting the effects of Coriolis acceleration and of uphill or downhill launches. An example is presented showing negligible differences between results from expressions derived herein and those from a well-developed and widely-used code that uses numerical integration. Such agreement can be expected for flat trajectories of projectiles with shapes resembling that of a standard, so-called G-7 projectile, in the supersonic speed range.

Published: January 2025

This study analyses the admission procedure for air traffic controller specialization applicants at the University of Defence in the Czech Republic. SWOT analysis identified strengths in the historically proven selection and it has also identified weaknesses in the assessment of air traffic controller-specific psychomotor skills. Key opportunities include integrating simulation technologies and enhancing collaboration with secondary schools. Key threats stem from outdated processes misaligned with Generation Z preferences and their declining interest in military fields. Recommended strategies focus on modernising the admissions process through simulation-based exercises, improving the promotion of the specialization, and adapting to the preferences of the current and future generation. The study provides a basis for evidence-based improvements in military air traffic controller candidate selection, emphasising a balanced approach between traditional and innovative assessment methods.
Sideritis carpetana (Labiatae), a new high-mountain Mediterranean species from the marble outcrops of the Sierra de Guadarrama (Central System, Madrid, Segovia, Spain)

Published: January 2025

A new species of Sideritis (Sideritis carpetana) is described from the calcareous, high-mountain Spanish flora in the central part of the Iberian Peninsula. It is found in a Mediterranean climate at high-elevation, perennial, calcareous grasslands, as well as in marble screes of anthropogenic origin in the Sierra de Guadarrama, Central System (Spain), in a reserve area within the Sierra de Guadarrama National Park, at 1996 m asl. Taxonomic morphological measurements were performed on collected specimens from Sierra de Guadarrama as well as on geographically-adjacent Sideritis (i.e., S. glacialis, S. pungens, S. hyssopifolia). The relationships among them were then explored with multivariate analysis. Sideritis carpetana is a dwarf shrub with an erect or decumbent habit, growing up to 15 cm; non-woody twigs with long hairs of 3–4 cells, leaves are entire, linear-oblanceolate, sparsely covered with trichomes; inflorescence is spiciform or slightly verticillated, flowers are yellow and nutlets ovoid. A key is supplied to help distinguish it from other high-mountain Iberian species included in section Sideritis. The species is unique in its combination of morphological and autoecological characters. S. carpetana shares similarities with S. glacialis, a species from Sierra Nevada, and its northern Mediterranean variant, S. glacialis subsp. fontqueriana from Sierra de Gúdar. They share morphological characters that are absent in other high-mountain Sideritis, reinforcing their Mediterranean character, as opposed to a more temperate or submediterranean character, such as those of the hyssopifolia group.
TBRAFusion: Infrared and visible image fusion based on two-branch residual attention Transformer
Authors: Zhang Wangwei , Sun Hao , Zhou Bin
Published: January 2025

The fusion of infrared and visible images highlights the target while preserving detailed information, which helps to comprehensively capture the scene information. However, the existing methods continue to face challenges in managing the integration of global and local information, as well as enhancing the extraction of detailed image features, thus ultimately leading to constrained fusion outcomes. To enhance the fusion effect, this paper proposes a dual-branch residual attention-based infrared and visible image fusion network (TBRAFusion). The network utilizes two key modules, TransNext and the dual-branch residual attention (DBRA) module, which are used to process the input images in parallel to extract contrast and detail information. Additionally, an auxiliary function is incorporated into the loss function. Compared with mainstream fusion models, TBRAFusion achieves better fusion results and metrics through these improvements. The experimental results on the TNO dataset show that TBRAFusion improves the metrics in entropy (EN), spatial frequency (SF), sum ofcorrelation differences (SCD), and visual information fidelity (VIF) by 0.42$ \% $, 4$ \% $, 3.9$ \% $, and 1.2$ \% $, respectively. Tests on the MSRDS dataset show improvements of 1.7$ \% $, 5.4$ \% $, 9.6$ \% $, and 4.9$ \% $ in EN, standard deviation (SD), SF, and SCD, respectively.

La presente contribución se propone analizar el recorrido de dos hispanistas, madre e hija: Yolanda Westphalen madre (1925-2011), poetisa y crítica literaria, y Yolanda Westphalen Rodríguez (1954-…) hija, que se dedicó a labores de critica literaria y editó la obra de su madre. Este estudio nos permitirá analizar las relaciones entre hombres y mujeres en la clase media intelectual peruana (siglos XX y XXI), sus condiciones de acceso al saber, a la escritura y a la reflexión sobre la escritura, pero también las relaciones de transmisión y de genealogía (biológica o intelectual). Se tratará asimismo de estudiar la biografía de estas dos mujeres, como sujetos históricamente situados, en el Perú contemporáneo, analizando en particular sus condiciones de acceso al mundo universitario o a ciertos campos específico del saber, como la crítica y la teoría literaria. La cuestión del ser mujer será el prisma a través del cual se analizarán estas dos vidas y, en particular, su reconocimiento y su relación con las instituciones (académicas, universitarias o editoriales).

Authors: Conde Margarita Moreno , Ramos Ruth Maicas
Published: January 2025

Nous présentons un panorama succinct du milieu archéologique et culturel où prend place la formation des premières conservatrices de musées en Espagne et l’influence française sur l’archéologie espagnole. Nous dressons également un bref portrait de ces premières femmes et analysons les difficultés qu’elles ont rencontrées à l’époque, ainsi que les raisons du silence qui a entouré leur carrière professionnelle par la suite. Nous concentrerons notre regard principalement, mais pas exclusivement, sur les professionnelles liées à l’archéologie ayant fait partie des générations formées dans le premier tiers du siècle dernier, notamment sur celles qui ont exercé leur activité à Madrid. La contribution de ces femmes, qui en général n’ont pas créé d’école et aux publications scientifiques limitées, a néanmoins été fondamentale pour la conservation, l’organisation et le catalogage de notre patrimoine, jetant ainsi les bases du travail scientifique des futurs professionnels des musées espagnols.
Renée Lafont et la revue Le Parthénon dans les années 1910 : au-delà de la traduction ?
Authors: Fintzel Julie
Published: January 2025

La contribution de Renée Lafont (1877-1936) à la connaissance de la culture espagnole en France et son rôle d’intermédiaire pour la réception des écrivains espagnols sont indéniables mais ont souvent été limités à son statut de traductrice des œuvres de Vicente Blasco Ibañez et de celles d’Alberto Insúa. Cet article vise à analyser d’autres moyens de transmission de la culture espagnole liés à Renée Lafont, dans les années 1910. Plus spécifiquement, il étudie les modalités de la collaboration de Renée Lafont à la revue Le Parthénon, et s’interroge sur les enjeux symboliques qui y sont attachés, en particulier concernant son insertion dans les milieux littéraires et en particulier les milieux littéraires masculins de l’époque.

Cada vez mais percebemos as marcas posicionando-se a partir de causas sociais. A temática da diversidade e da inclusão parece ser o assunto da vez. Nossa intenção é cartografar a presença das causas sociais nos discursos contemporâneos das marcas. Para tanto, a partir do escopo teórico da publicidade de causa e metodológico da cartografia, imergimos no acervo do Clube da Criação e analisamos as publicações de 2022 e 2023, buscando identificar o grau de engajamento das marcas anunciantes em relação às causas. Ao final, concluímos que a maior parte das campanhas publicitárias se enquadram nos níveis de plataforma e protagonista. Já o marcador mais recorrente é o de identidade de gênero, enquanto a causa menos abordada é a etária e a geracional.

Este trabalho propõe rever os significados que a cartografia da/na comunicação poderá suscitar quando em confronto com uma experiência empírica. Apresenta-se alguns modos de conceituar cartografia na comunicação como modos de conhecer insurgentes à equivalência mapa-território. Nesse sentido compara-se a exposição “Eu, Villa Adriana” de Luca Vitone em São Paulo e Roma. A análise mostra: Roteiros das mediações que se pretendem equivalentes ao território; Trajetos suscitados pela interação entre sujeitos; Deriva como estratégia heurística que faz navegar pelo imprevisível dos lugares do território, desfazendo a certificação dos lugares mapeados, no jogo visualidade/visibilidade. A experiência faz diferença para uma epistemologia que, ao cartografar o movimento dos possíveis significados do conceito, visibiliza uma cartografia do comunicar nos modos de ver/olhar, falar/dizer, conhecer/pensar e permite revisão dos sentidos do já visto/sabido, incorporando à cartografia o risco da surpresa.

Published: January 2025

The identification of etiology is very important when managing patients with community-acquired pneumonia (CAP). In Pakistan, studies regarding the viral etiology in CAP are scarce. The main objective of this study was to evaluate the frequency of viral etiology in CAP patients and analyze the clinical features and their impact on prognosis. Medical records of CAP patients admitted to Aga Khan University Hospital (Karachi, Pakistan) from March 2022 to February 2023 were retrospectively reviewed, patients who had microbiological tests performed within 48 hours of the hospital admission were included, and the frequency of viral and bacterial etiology was calculated. Patients who were immunocompromised were excluded. Epidemiological and clinical characteristics were examined, and the impact on prognosis was explored. A total of 166 patients were included; 115 (69.3%) patients were identified as having pneumonia with known causative microorganisms. A total of 83 (72.1%) patients had a viral etiology alone, 18 (15.6%) had only bacterial infection, and 14 (12.2%) had a viral and bacterial co-infection. Influenza A was most frequently detected (n=46/97; 47.4%), followed by Rhinovirus/Enterovirus (n=19/97; 19.6%). Staphylococcus aureus accounted for the majority (n=18; 56.3%) of cases among bacteria. Bacterial and viral-bacterial co-infection was significantly higher among non-survivors (38.1% vs. 16.6%, p=0.034). Confusion-Urea-Respiratory Rate-Blood Pressure-Age of 65 scores of 3-5 [odds ratio (OR) 4.234; 95% confidence interval 1.156-15.501], leukocytosis (OR 0.137; 0.030-0.636), high C-reactive protein (>10mg/L) (OR 1.008; 1.001-1.014), high serum procalcitonin level (≥0.5 ng/mL) (OR 10.731; 3.018-38.153), and mechanical ventilation required (OR 47.104; 13.644-162.625) were associated with mortality. Mechanical ventilation requirement was independently associated with increased odds of mortality (OR 43.407; 8.083-233.085). Of 166 patients, 21 (12.7%) had died, with the highest percentage (28.6%) seen in the viral-bacterial coinfection group (p=0.046). To conclude, respiratory viruses are increasingly being recognized as an important etiology in CAP, with higher mortality seen in bacterial infection, whether alone or with viral co-infection.

Hirayama disease (HD) is a rare neurological disorder. It is a focal, lower motor neuron disease, mainly affecting young males in their second and third decades. It is prevalent most commonly in Asian countries like Japan. Magnetic resonance imaging (MRI) of the cervical spine in flexion will reveal the hallmark features of Hirayama disease. A 22-year-old male presented with a history of insidious weakness of the left hand for 2 years. On examination, he had clawing of the left medial three fingers with wasting of left forearm muscles, which was progressive in nature. MRI showed thinning of the spinal cord from C3 to C7 level, suggestive of cord atrophy. Based on these features, a diagnosis of focal amyotrophy was made. As the patient was non-compliant with the use of the cervical collar, resulting in the progression of symptoms, C3–C6 lateral mass fixation without fusion was performed to stop the progression of the disease and to facilitate implant removal at a later stage and regain cervical motion. Early diagnosis is necessary as the use of a simple cervical collar, which will prevent neck flexion, has been shown to stop the progression in the majority of the cases.

The excessive buildup of neurotoxic α-synuclein plays a pivotal role in the pathogenesis of Parkinson's disease, highlighting the urgent need for innovative therapeutic strategies to promote α-synuclein clearance, particularly given the current lack of disease-modifying treatments. The glymphatic system, a recently identified perivascular fluid transport network, is crucial for clearing neurotoxic proteins. This review aims to synthesize current knowledge on the role of the glymphatic system in α-synuclein clearance and its implications for the pathology of Parkinson's disease while emphasizing potential therapeutic strategies and areas for future research. The review begins with an overview of the glymphatic system and details its anatomical structure and physiological functions that facilitate cerebrospinal fluid circulation and waste clearance. It summarizes emerging evidence from neuroimaging and experimental studies that highlight the close correlation between the glymphatic system and clinical symptom severity in patients with Parkinson's disease, as well as the effect of glymphatic dysfunction on α-synuclein accumulation in Parkinson's disease models. Subsequently, the review summarizes the mechanisms of glymphatic system impairment in Parkinson's disease, including sleep disturbances, aquaporin-4 impairment, and mitochondrial dysfunction, all of which diminish glymphatic system efficiency. This creates a vicious cycle that exacerbates α-synuclein accumulation and worsens Parkinson's disease. The therapeutic perspectives section outlines strategies for enhancing glymphatic activity, such as improving sleep quality and pharmacologically targeting aquaporin-4 or its subcellular localization. Promising interventions include deep brain stimulation, melatonin supplementation, γ-aminobutyric acid modulation, and non-invasive methods (such as exercise and bright-light therapy), multisensory γ stimulation, and ultrasound therapy. Moreover, identifying neuroimaging biomarkers to assess glymphatic flow as an indicator of α-synuclein burden could refine Parkinson's disease diagnosis and track disease progression. In conclusion, the review highlights the critical role of the glymphatic system in α-synuclein clearance and its potential as a therapeutic target in Parkinson's disease. It advocates for further research to elucidate the specific mechanisms by which the glymphatic system clears misfolded α-synuclein and the development of imaging biomarkers to monitor glymphatic activity in patients with Parkinson's disease. Findings from this review suggest that enhancing glymphatic clearance is a promising strategy for reducing α-synuclein deposits and mitigating the progression of Parkinson's disease.
Enhanced neurogenesis after ischemic stroke: the interplay between endogenous and exogenous stem cells

Published: January 2025

Ischemic stroke is a significant global health crisis, frequently resulting in disability or death, with limited therapeutic interventions available. Although various intrinsic reparative processes are initiated within the ischemic brain, these mechanisms are often insufficient to restore neuronal functionality. This has led to intensive investigation into the use of exogenous stem cells as a potential therapeutic option. This comprehensive review outlines the ontogeny and mechanisms of activation of endogenous neural stem cells within the adult brain following ischemic events, with focus on the impact of stem cell-based therapies on neural stem cells. Exogenous stem cells have been shown to enhance the proliferation of endogenous neural stem cells via direct cell-to-cell contact and through the secretion of growth factors and exosomes. Additionally, implanted stem cells may recruit host stem cells from their niches to the infarct area by establishing so-called “biobridges.” Furthermore, xenogeneic and allogeneic stem cells can modify the microenvironment of the infarcted brain tissue through immunomodulatory and angiogenic effects, thereby supporting endogenous neuroregeneration. Given the convergence of regulatory pathways between exogenous and endogenous stem cells and the necessity for a supportive microenvironment, we discuss three strategies to simultaneously enhance the therapeutic efficacy of both cell types. These approaches include: (1) co-administration of various growth factors and pharmacological agents alongside stem cell transplantation to reduce stem cell apoptosis; (2) synergistic administration of stem cells and their exosomes to amplify paracrine effects; and (3) integration of stem cells within hydrogels, which provide a protective scaffold for the implanted cells while facilitating the regeneration of neural tissue and the reconstitution of neural circuits. This comprehensive review highlights the interactions and shared regulatory mechanisms between endogenous neural stem cells and exogenously implanted stem cells and may offer new insights for improving the efficacy of stem cell-based therapies in the treatment of ischemic stroke.
Epilepsy therapy beyond neurons: unveiling astrocytes as cellular targets

Published: January 2025

Epilepsy is a leading cause of disability and mortality worldwide. However, despite the availability of more than 20 antiseizure medications, more than one-third of patients continue to experience seizures. Given the urgent need to explore new treatment strategies for epilepsy, recent research has highlighted the potential of targeting gliosis, metabolic disturbances, and neural circuit abnormalities as therapeutic strategies. Astrocytes, the largest group of nonneuronal cells in the central nervous system, play several crucial roles in maintaining ionic and energy metabolic homeostasis in neurons, regulating neurotransmitter levels, and modulating synaptic plasticity. This article briefly reviews the critical role of astrocytes in maintaining balance within the central nervous system. Building on previous research, we discuss how astrocyte dysfunction contributes to the onset and progression of epilepsy through four key aspects: the imbalance between excitatory and inhibitory neuronal signaling, dysregulation of metabolic homeostasis in the neuronal microenvironment, neuroinflammation, and the formation of abnormal neural circuits. We summarize relevant basic research conducted over the past 5 years that has focused on modulating astrocytes as a therapeutic approach for epilepsy. We categorize the therapeutic targets proposed by these studies into four areas: restoration of the excitation-inhibition balance, reestablishment of metabolic homeostasis, modulation of immune and inflammatory responses, and reconstruction of abnormal neural circuits. These targets correspond to the pathophysiological mechanisms by which astrocytes contribute to epilepsy. Additionally, we need to consider the potential challenges and limitations of translating these identified therapeutic targets into clinical treatments. These limitations arise from interspecies differences between humans and animal models, as well as the complex comorbidities associated with epilepsy in humans. We also highlight valuable future research directions worth exploring in the treatment of epilepsy and the regulation of astrocytes, such as gene therapy and imaging strategies. The findings presented in this review may help open new therapeutic avenues for patients with drug-resistant epilepsy and for those suffering from other central nervous system disorders associated with astrocytic dysfunction.

A 54-year-old female was referred because of a pigmented iris lesion with uncontrolled glaucoma in the left eye. The intraocular pressure (IOP) was 54 mm Hg despite anti-glaucoma medications. Her visual acuity (VA) was 20/100. A slit-lamp examination showed corneal edema and a darkly pigmented small iridociliary lesion (Ultrasound biomicroscopy: 5 mm × 3 mm × 2 mm) with diffuse pigment shedding onto the anterior iris surface and diffuse circumferential pigmentation of the trabecular meshwork with wide-open angle (gonioscopy). Diagnostic fine needle aspiration biopsy of the main tumor and anterior chamber lavage were performed. Cytology revealed polygonal cells with dense intracytoplasmic pigment obscuring nuclear details diagnostic of a melanocytoma. During follow-up, as the tumor continued to cause new pigment shedding with high IOP, therefore, excision of the primary tumor via iridocyclectomy was performed. At postoperative 1 month, the IOP was 13 mm Hg with maximal medical therapy for glaucoma requiring glaucoma shunt surgery. At 6 months, the IOP remained below 13 mm Hg and the VA was 20/50 without recurrence of pigment shedding. Necrotic iris melanocytoma, though rare, can lead to pigment dispersion glaucoma. Surgical excision of the primary tumor, coupled with glaucoma surgery, proved effective in controlling intraocular pressure and preserving vision in this case.

Published: January 2025

The project aims to design an intelligent road eye by using AI and a machine learning approach to detect speedbumps and potholes on the road. The system design utilizes a YOLOv5 custom-trained model and COCO dataset in detecting the objects on the road. The system is integrated with lane detection algorithms to achieve active steering feedback and pothole avoidance. Based on the detection results, feedback will be given in the form of visual, audio, and steering angles, allowing the driver to have sufficient response time to perform braking or steering adjustments where applicable. The trained model can achieve a mean average precision value (mAP) of up to 0.995 for all classes, and a maximum detection range of 5.77m and 34.8m for potholes and speedbump respectively. The future works of the project include integrating the algorithm into the vehicle to achieve autonomous braking and active pothole avoidance with the help of sensors and cameras on the vehicle, as well as adopting augmented reality (AR) to project the visual feedback on the vehicle windscreen.
