SPADE: A Deep Learning Framework for Spatial Mapping and Quantitative Cell–Cell Interaction Inference

open access: yesAdvanced Science, EarlyView.
SPADE integrates spatial transcriptomics with single‐cell RNA sequencing by using cell–cell communications (CCC) as a guide for spatial mapping. It improves cell‐type localization, enhances sparse gene‐expression signals, and reveals CCC programs at single‐spot resolution.

Towards the Curvature Cuff of a Canal Surface

open access: yes, 2007
By means of a special stereographic mapping, a sphere corresponds to a point in 4-space. A canal surface then corresponds to a curve in 4-space. The poster gives insights into this mapping and presents a construction of an osculating Dupin cyclide ...

Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

open access: yesAdvanced Science, EarlyView.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Micro-computed tomographic evaluation of the shaping ability of three nickel-titanium rotary systems in the middle mesial canal of mandibular first molars: an ex vivo study based on 3D printed tooth replicas

open access: yesBMC Oral Health
Background The preparation of the middle mesial (MM) canal of mandibular molars represents a challenge because it is often curved, narrow, and close to the root concave.

A Pancreatitis‐Inspired Trypsinogen Nanoplatform Reprograms Tumor‐Associated Macrophages via NF‐κB for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Trypsinogen‐loaded nanoparticles reprogram TAMs via NF‐κB/NLRP3, driving M2→M1 conversion and potent phagocytosis to unleash antitumor immunity. ABSTRACT Although reprogramming tumor‐associated macrophages (TAMs) represents a promising therapeutic strategy, approaches that are both precise and safe remain scarce.

Mucoadhesive Peptide‐Catalase Self‐Assembled Nano‐Formulation for Effective Treatment of Mucosal Inflammatory Diseases

open access: yesAdvanced Science, EarlyView.
CR8L10 is self‐assembled with catalase (CAT) to form CR8L10@CAT nanocomplexes, which can anchor to mucosal surfaces via thiol‐disulfide exchange with mucin, thereby enhancing their mucosal retention. The efficient reactive oxygen species (ROS) scavenging at inflamed sites would then result in successful treatment in both the intravesical IC/BPS model ...
