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 ...

Multimodal Imaging of Hypoxia, Metabolism and pH in Feline Sarcoma Using Hyperpolarized 13C MRI and PET

open access: yesAdvanced Science, EarlyView.
This work presents a clinically deployable simultaneous PET/MRI workflow which integrates hyperpolarized 13C imaging of metabolism and extracellular pH with [18F]FMISO PET to characterize hypoxia, acidosis, and metabolic reprogramming in feline sarcoma.

Hierarchical Nanoplatform Integrating Oxidative–Acidic Microenvironment Remodeling and Bone Homeostasis Modulation for Diabetic Bone Defect Therapy

open access: yesAdvanced Science, EarlyView.
A hierarchical CM/LDH nanoplatform integrates ROS‐scavenging Ce‐MOF nanozymes with acid‐neutralizing CaAl‐LDH and is delivered within GelMA hydrogel to diabetic bone defects. By remodeling the oxidative‐acidic microenvironment, preserving mitochondrial homeostasis, and suppressing mtDNA–cGAS–STING inflammatory signaling, CM/LDH reduces proinflammatory ...

Perioperative metabolic acidosis: The Bradford Anaesthetic Department Acidosis Study

open access: yes, 2018
Metabolic acidosis is considered deleterious but is common in post-surgical patients admitted to intensive care unit. We evaluated the prevalence and time course of metabolic acidosis in elective major surgery, and generated hypotheses about causes, by ...

Cannabinoid CB1 Receptor in Nociceptors Mediates Postoperative Analgesia via ASIC3 Inhibition

open access: yesAdvanced Science, EarlyView.
CB1R and ASIC3 are co‐expressed in CGRP+ nociceptors of mouse DRG. Plantar incision triggers an upregulation of ASIC3 and activation of ASIC3+ neurons, driving mechanical allodynia. CB1R activation suppresses ASIC3 function and downstream ERK1/2 phosphorylation, thereby braking nociceptive signaling and accelerating pain resolution.

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

open access: yesAdvanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Quantification of Metabolic Acidosis at Bedside by S.A.L.T Approach

open access: yesJournal of Emergencies, Trauma and Shock
Introduction: Traditionally, metabolic acidosis is analyzed using an anion gap (AG). The aim of the study was to compare the utility of quantitative David Story’s simplified Stewart approach against traditional approach to analyze metabolic acidosis. ICU

Response of LLC-PK1-F+ cells to metabolic acidosis

open access: yes, 1996
The role of extracellular glutamate formation as opposed to cellular glutamate removal in regulating monolayer glutamate content in response to metabolic acidosis was studied in LLC-PK1-F+ cells. Exposure to metabolic acidosis (14 mM bicarbonate; pH 7.1)

Lactate Homeostasis Disruption Potentiates TACE‐Immunotherapy in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Lactate homeostasis is disrupted through spatially coordinated extracellular neutralization and intracellular acidification, triggering calcium overload, mitochondrial dysfunction, and immunogenic cell death. This metabolic reprogramming alleviates the immunosuppressive tumor microenvironment and enhances immune checkpoint blockade, providing a ...
