Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

Advanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

Advanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

A novel rat model of pulmonary artery embolism and the application value of lung ultrasound B‐lines in early‐stage pulmonary embolism

Animal Models and Experimental Medicine, EarlyView.
We report a novel embolus‐induced PE rat model prepared via the inferior vena cava under ultrasound guidance. The embolus employed featured a tubular plastic casing filled with thrombus. By minimizing the contact surface between plasmin and thrombus, it effectively restrains the elevated plasmin activity in rats.

Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis

Advanced NanoBiomed Research, EarlyView.
Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...
