A Modular Perfusion Bioreactor Platform for Simulating Bone Regeneration and Fracture Healing: Integrating Mechanical Loading and Dual Perfusion for Advanced In Vitro Models

Advanced Healthcare Materials, EarlyView.
A modular bioreactor platform was developed in order to replicate bone homeostasis and pathology, thereby integrating mechanical loading, dynamic perfusion, and a 3D‐printed microfluidic chamber. With precise control of environmental parameters and dual perfusion for composite tissue models, the system enhances physiological relevance for studying bone

Glucose Deprivation‐Induced Disulfidptosis via the SLC7A11‐INF2 Axis: Pan‐Cancer Prognostic Exploration and Therapeutic Validation

Advanced Science, EarlyView.
Glucose deprivation or GLUT1 inhibition induces disulfidptosis in SLC7A11high ovarian cancer cells by promoting cystine accumulation, NADPH/ATP depletion, and F‐actin disulfide formation. SLC7A11 interacts with INF2 to further increase H₂O₂ levels and impair mitochondrial fission, suppressing cell migration. Targeting the SLC7A11–INF2 axis represents a

Severe Self-Inflicted Acute Ocular Siderosis Caused by an Iron Tablet in the Conjunctival Fornix

Acta Medica, 2018
We present the case of a female patient who grinded a ferrous sulfate tablet and placed it at the conjunctival fornix of her left eye. She rapidly developed severe ocular siderosis, with profoundly decreased visual acuity, corneal opacities, cataract ...

STAT6 Activation Exacerbates Ferroptosis in Airway Epithelium by Inhibiting PRKN‐Mediated Mitophagy in Pulmonary Fibrosis

Advanced Science, EarlyView.
This study uncovers STAT6‐driven pulmonary fibrosis (PF) via suppression of PRKN‐mediated airway epithelial mitophagy, triggering mitochondrial dysfunction and ferroptosis. Rifabutin is identified as a potent STAT6 inhibitor that effectively reverses fibrotic progression. These findings reveal the STAT6‐PRKN axis as a pathogenic regulator and provide a

The COST-UTILITY ANALYSIS OF FOUR CHELATION REGIMENS FOR Β-THALASSEMIA MAJOR: A CHINESE PERSPECTIVE

Mediterranean Journal of Hematology and Infectious Diseases, 2020
Background: The four most commonly used chelation regimens for β-thalassemia major patients in China are a combination therapy of deferoxamine and deferiprone (DFO+DFP), deferoxamine(DFO) monotherapy, deferiprone(DFP) monotherapy and deferasirox(DFX ...

Lipocalin-2 Restores Soluble Guanylyl Cyclase-Dependent Dilation of the Afferent Arteriole After Renal Transplantation or Ex Vivo Hypoxia/Reoxygenation in Mice. [PDF]

Acta Physiol (Oxf)
ABSTRACT Aim Dilatory microvascular function is impaired in ischemia/reperfusion injury in the kidney. Nitric oxide independent activators of soluble guanylyl cyclase (sGC) provide renal protection by dilating microvessels and preserving perfusion, but their efficacy declines after severe hypoxia.

PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

Advanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.

Deferoxamine and Sweat Iron.

Experimental Biology and Medicine, 1967
ConclusionsIron excretion in sweat from the forearm of normal subjects and patients with iron overload is similar, with values in the lower range of normal. Deferoxamine has no appreciable effect on sweat iron concentration.The author wishes to express his appreciation to Dr. Elmer B. Brown for encouragement and valuable criticism during this work, and

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

Advanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem
