Deciphering Anti‐Cancer Drug Efficacy Through Nanomechanical Vibrations in Living Gastric Cancer Organoids

open access: yesAdvanced Science, EarlyView.
This study developed an efficacy assessment platform that integrates patient‐derived gastric cancer organoids, atomic force microscopy (AFM)‐based nanomechanical vibration detection, deep learning analysis, and organoid mechanical modeling. It detects picomolar drug effects within 0.1 s signal, achieves 97% classification accuracy, and offers non ...

Bending‐Stable Pressure Sensor Based on Natural Wood Nanofibers for Ultra‐Low Detection Limit

open access: yesAdvanced Science, EarlyView.
A wood nanofiber‐based flexible pressure sensor with intrinsic bending‐stable performance is developed through a porous electrospun architecture and interdigital electrode design. The device exhibits an ultra‐low detection limit and stable operation under deformation for physiological monitoring and spatial sensing, providing a sustainable strategy for

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

open access: yesAdvanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Rate versus rhythm control in atrial fibrillation in the geriatric population — clinical outcomes, comorbidities, and therapeutic implications

open access: yesFolia Cardiologica
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with a prevalence exceeding 10% in individuals > 75 years of age. In elderly patients, AF is associated with an increased risk of stroke, heart failure, hospitalization, and ...

Developing Soft Interconnected Microchannel Network for 2D Skin‐Like Actuator

open access: yesAdvanced Science, EarlyView.
A soft interconnected network of microchannels is proposed to develop new pneumatic actuators for future bio‐inspired soft robots. Simultaneous stimulation of this network generates regional asymmetric strains in walls of microchannels whose interaction across the entire surface leads to bending curvatures in multidimensions.

Atrial Fibrillation Postoperative Cardiac Surgery: A Literature Review of Recurrence, Stroke Risk, and Management Approaches

open access: yesThe Heart Surgery Forum
Postoperative atrial fibrillation (POAF) is the most common complication following cardiac surgery. While often considered a transient and expected complication, recent evidence suggests that POAF is associated with an increased risk of recurrence ...

Melatonin secretion in a strictly subterranean mammal, the Damaraland mole-rat (Cryptomys damarensis) [PDF]

open access: yes, 2003
Subterranean mammals inhabit an environment that is normally devoid of light and are therefore deprived of photoperiodic information that can be used to time important life-history events.

Machine Learning‐Driven Design of Multicomponent Bone Inorganic Matrix Mimicking Scaffolds for Osteogenesis Enhanced by Neurogenesis

open access: yesAdvanced Science, EarlyView.
Schematic illustration of development of experimental datasets and algorithm models, screening and preparation of the scaffolds and their applications in vivo. ABSTRACT Bone defects require materials with osteogenic, neurogenic, and angiogenic activity, yet designing such materials within high‐dimensional compositional spaces remains challenging. Here,

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

open access: yesAdvanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...
