Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

open access: yesAdvanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Versatile Microgel Platform for Intervertebral Disc Degeneration Therapy: Targeting Pericyte‐Mediated Fibrosis and Protecting Nucleus Pulposus Cells

open access: yesAdvanced Science, EarlyView.
The engineered MMS@TRP microgel enables targeted, acid‐responsive delivery of a miR‐21 inhibitor to pericytes. It effectively suppresses disc fibrosis by inhibiting TGF‐β signaling while protecting nucleus pulposus cells via sustained, antioxidant tannic acid release.

India’s Nepal Policy (1950-2020) and Globalisation in Nepal: Challenges within and from China

open access: yesGlocalism: Journal of Culture, Politics and Innovation, 2021
Seventy years (1950-2020) of India’s diplomatic ties with Nepal have been defined by deep-rooted socio-cultural, economic and people to people relations. The two countries share an open border that is nowhere found in a contested South Asia.

Gut Microbial Topology and Metabolic Signatures Associated With Colorectal Neoplasia

open access: yesAdvanced Science, EarlyView.
The gut microbiota organizes into two robust association patterns linked to colorectal neoplasia risk. Topological shifts in microbial networks are associated with metabolite alterations and may shape host responses during disease development. ABSTRACT Alterations of gut microbial communities impact health.

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Comparison of rat hypertrophic scar models: Caudal tension model with superior pathological consistency

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This study compared hypertrophic scar (HS) formation in SD rats at ear, back, and tail sites with or without mechanical tension. The ear model healed spontaneously by day 30. Dorsal full‐thickness excision (1 × 8 cm) produced moderate HS. In contrast, the tail tension model showed the greatest scar thickness, fibroblast density, collagen deposition ...

The effective elastic thickness of the India Plate from receiver function imaging, gravity anomalies and thermomechanical modelling [PDF]

open access: yes, 2006
The range and the meaning of the effective elastic thickness (EET) in continental areas have been subject to controversy over the last two decades. Here we take advantage of the new data set from the Hi-CLIMB seismological experiment to re-estimate the ...
