Single‐Cell Transcriptomic Profiling Identifies B Cell‐Intrinsic Dysregulation of Sphingolipid Biosynthesis and Could Be Improved by Inhibiting UGCG in Primary Immune Thrombocytopenia

Advanced Science, EarlyView.
This study generates the single‐cell atlas of pathogenic B‐cell subset Bc‐5 in ITP. It identifies RUNX3 as a key survival regulator and uncovers sphingolipid‐driven metabolic reprogramming, validating UGCG inhibition as a therapeutic candidate and building a valuable resource for ITP mechanistic and therapeutic exploration.

An Expertise Transfer Framework For Autonomous Surgical Assistance

Advanced Science, EarlyView.
This study introduces an expertise transfer framework for procedure‐spanning autonomous surgical assistance. By emulating expert logic through hierarchical perception, attention modeling, and knowledge graph‐based decision‐making, the system provides near‐expert surgical view assistance.

SPIN-SGG: spatial integration for open-vocabulary scene graph generation

Journal of King Saud University: Computer and Information Sciences
Scene Graph Generation (SGG) aims to represent visual scenes as structured graphs, where objects and their pairwise relationships are modeled as relational triples. However, conventional SGG methods often struggle with two crucial limitations: inadequate

Single‐Nucleus Transcriptomic Atlas of Human Vellus Hair Pilosebaceous Units Reveals Age‐Associated Remodeling

Advanced Science, EarlyView.
Human vellus pilosebaceous units (PSUs) remain uncharted. This single‐nucleus atlas reveals coordinated remodeling of the aging PSU niche: reduced bulge stem cell representation with altered regenerative programs, increased representation of a stress‐responsive channel+ epithelial state, enhanced androgen‐responsive sebaceous programs, reduced ...

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

Advanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.

Single‐Cell Insights Into Pathogenic Profile of Orchitis and SREBP2‐Associated Cholesterol Dysregulation in Spermatogenic Failure

Advanced Science, EarlyView.
A first single‐cell atlas of human orchitis reveals coordinated germ‐cell loss, somatic niche dysfunction, and immune‐metabolic remodeling. Aberrant SREBP2 activation in testicular somatic cells emerges as a central pathogenic node, while Fatostatin‐mediated inhibition of the SREBP pathway improves spermatogenesis, fibrosis, and lipid accumulation in a

Scene Graph Adapter: An efficient Architecture to Improve Interoperability between 3D Formats and 3D Application Engines [PDF]

, 2011
International audienceWe present a generic architecture which enables the loading of several 3D formats in most 3D application engines. The purpose of this work is to solve the interoperability issue among 3D formats raised by the multiplicity of formats.

Rethinking Cochlear Implants: The Need for Precise Temporal Coding

Advanced Science, EarlyView.
Spatial hearing relies on sensitivity to interaural temporal cues, but this sensitivity is often poorly developed in patients with cochlear implants, particularly those with early‐onset hearing loss. Rats with cochlear implants, however, demonstrate excellent temporal sensitivity, suggesting that this limitation is not inevitable.

SGFormer: Semantic Graph Transformer for Point Cloud-based 3D Scene Graph Generation [PDF]

, 2023
In this paper, we propose a novel model called SGFormer, Semantic Graph TransFormer for point cloud-based 3D scene graph generation. The task aims to parse a point cloud-based scene into a semantic structural graph, with the core challenge of modeling ...
