Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

open access: yesAdvanced Science, EarlyView.
Machine learning models predict in real time the onset of harmful microbubble collapse during microbubble‐enhanced focused ultrasound (MB‐FUS) and enable dynamic adjustment of sonication to prevent cavitation‐induced damage. This predictive control expands the safe operating window for bloodbrain barrier opening, enhancing nanoparticle delivery and ...

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

open access: yesAdvanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Resilient Calvarial Bone Marrow Supports Retinal Repair in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
Skull bone (calvarium) marrow in diabetic mice stay structurally intact and keeps making blood cells, unlike the bone marrow of the leg bones. The skull marrow is exposed to cerebrospinal fluid (CSF), which contains protective molecules called oxysterols.

Amelioration of Post‐Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System

open access: yesAdvanced Science, EarlyView.
Compared to untargeted therapy, the targeted nanocarrier, Angiopep‐2‐conjugated Lipid Nanoparticle (A‐LNP) loaded with TGN‐020 (TGN), selectively accumulated in stroke‐injured regions. It suppressed local aquaporin‐4 (AQP4) overexpression, thereby alleviating cerebral edema and hypoperfusion while preserving global glymphatic clearance.

Longitudinal RNA-Seq analysis of acute and chronic neurogenic skeletal muscle atrophy. [PDF]

open access: yes, 2019
Skeletal muscle is a highly adaptable tissue capable of changes in size, contractility, and metabolism according to functional demands. Atrophy is a decline in mass and strength caused by pathologic loss of myofibrillar proteins, and can result from ...

Schwann Cell Synthesized Cholesterol Orchestrates Peripheral Nerve Regeneration via Structural and IGF1‐Dependent Signaling Mechanisms

open access: yesAdvanced Science, EarlyView.
This study reveals that Schwann cell FDFT1‐mediated cholesterol synthesis is essential for peripheral nerve regeneration via dual roles: as a structural component for myelin and as a metabolic signal that upregulates IGF1. IGF1 promotes axonal growth through paracrine action and enhances Schwann cell differentiation/ myelination via an intrinsic IGF1R ...

H2S‐Releasing Aspirin Nanoparticles Alleviate Endometriosis and Associated Anxiety

open access: yesAdvanced Science, EarlyView.
Albumin nanoparticles loaded with an H2S‐releasing aspirin derivative (ACS14) hitchhiking neutrophils after intraperitoneal injection and preferentially accumulate in endometriosis lesions in mice. The treatment suppresses lesion growth by regulating PI3K/Akt and reduces inflammation by inhibiting NF‐κB.

Single‐Cell Morphomechanics of Prostate Cancer‐Associated Fibroblasts Identifies Distinct Features Associated with Patient Outcome

open access: yesAdvanced Science, EarlyView.
Cancer‐associated fibroblasts (CAFs) in prostate tumors exhibit distinct morphomechanical traits vs normal fibroblasts, including greater stiffness and volume, more elongated stress fibres, and larger and more elongated nuclei. These features, quantified through imaging and real‐time deformability cytometry, correlate with patient outcomes and can be ...

Microendovascular Neural Recording from Cortical and Deep Vessels with High Precision and Minimal Invasiveness

open access: yesAdvanced Intelligent Systems, EarlyView.
Intravascular electroencephalography (ivEEG) using micro‐intravascular electrodes was developed. Cortical‐vein ivEEG showed a higher signal‐to‐noise ratio and finer spatial resolution of somatosensory evoked potentials (SEPs) than superior sagittal sinus ivEEG, and deep‐vein ivEEG captured clear visual evoked potentials.
