Multicellular tumor-stromal interactions recapitulate aspects of therapeutic response and human oncogenic signaling in a 3D disease model for H3K27M-altered DIPG.

It has become evident from decades of clinical trials that multimodal therapeutic approaches with focus on cell intrinsic and microenvironmental cues are needed to improve understanding and treat the rare, inoperable, and ultimately fatal diffuse intrinsic pontine glioma (DIPG), now categorized as a diffuse midline glioma. In this study we report the development and characterization of an in vitro system utilizing 3D Tumor Tissue Analogs (TTA), designed to replicate the intricate DIPG microenvironment. The innate ability of fluorescently labeled human brain endothelial cells, microglia, and patient-derived DIPG cell lines to self-assemble has been exploited to generate multicellular 3D TTAs that mimic tissue-like microstructures, enabling an in- depth exploration of the spatio-temporal dynamics between neoplastic and stromal cells.

Transcriptomic Analysis Corroborates the New Radial Model of the Mouse Pallial Amygdala.

The mammalian amygdala is located in the temporal lobe of the telencephalon and plays a key role in limbic processing. Recently, our group proposed a radial morphological model to understand the glutamatergic (pallial) part of this nuclear complex in terms of separate progenitor domains. This model explains the amygdala region as consisting of several adjacent developmental radial progenitor units, disposing their distinct periventricular, intermediate, and superficial strata from the ventricle to the pial surface.

Prospective Evaluation of the Impact of Sedation During LAAO on Cognitive Function Using Oculomotor Biomarkers.

Background: Intracardiac echocardiography guidance has emerged as a feasible alternative to transesophageal echocardiography in guiding left atrial appendage occlusion (LAAO). A proposed advantage of this approach is the avoidance of cognitive impairment associated with general anesthesia (GA) in elderly patients.

Objectives: We studied the effect of anesthesia method (GA vs moderate sedation [MS]) on cognitive function using a novel digital oculomotor biomarker.

Clinical spectrum, imaging characteristics, and treatment outcomes of pediatric adrenocortical tumors: a 24-year experience from Western India.

Objectives: This study aims to characterize the clinical spectrum of pediatric adrenocortical tumors (P-ACTs) in individuals aged <20 years and to compare the distinguishing features of pediatric adrenocortical adenomas (P-ACAs) and carcinomas (P-ACCs).

Methods: This retrospective study consisted of P-ACT patients who presented to our institute over the past 24 years (2001-2024). They were categorized as P-ACC or P-ACA based on Wieneke score.

Vitamin D enhances antiviral responses in dengue virus-infected macrophages by modulating early-response gene expression.

Dengue virus (DENV), the etiological agent of dengue fever, remains a global health concern, leading to severe illness and death in the absence of any definitive cure. Research has shown that vitamin D may reduce DENV replication in vitro and that dengue patients with low or deficient vitamin D levels are at higher risk of severe dengue. Studies indicate that viral replication is inhibited in human monocyte-derived macrophages (MDM) differentiated in the presence of vitamin D (D3MDM), suggesting that vitamin D may prevent DENV entry into host cells.
