PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Occlusion of retinal capillaries caused by glial cell proliferation in chronic ocular inflammation [PDF]

, 2015
The inner blood-retinal barrier is a gliovascular unit in which glial cells surround capillary endothelial cells and regulate retinal capillaries by paracrine interactions.

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

Advanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Synchrotron Radiation‐Based Tomography of an Entire Mouse Brain with Sub‐Micron Voxels: Augmenting Interactive Brain Atlases with Terabyte Data

Advanced Science, EarlyView.
Extended‐field acquisition enables sub‐micron X‐ray imaging of a full mouse brain. The 3.3‐teravoxel volume is reconstructed, registered to a reference atlas, and stored in hierarchical format to augment currently available atlases and improve resolution in the third dimension by an order of magnitude.

Film handling procedures for Skylab S-056 experiment [PDF]

In a simulation conducted August 28, 1972, two rolls of Type SO-212 film were rewound in the sensitometer darkroom preparatory to processing. The first roll contained approximately 500 feet of film exposed to a resolution target and was unloaded from a ...

Red Blood Cell‐Induced Bacterial Margination Improves Microbial Hemoadsorption on Engineered Cell‐Depleted Thrombi, Restoring Severe Bacteremia in Rats

Advanced Science, EarlyView.
A highly efficient extracorporeal device for treating bacteremia is developed by integrating microfluidic bacterial margination and engineered cell‐depleted thrombi strategically constructed in the device. The rodent models, severely infected with antibiotic‐resistant bacteria, recover from bacteremia after two subsequent extracorporeal blood ...

SMC4 Promotes Prostate Cancer Cell Proliferation and Metastasis via the Rheb/mTOR Pathway

Advanced Science, EarlyView.
Structural maintenance of chromosome protein 4 (SMC4) has been implicated in prostate cancer metastasis. Knockdown of SMC4 in RM1‐LM cells significantly attenuates proliferation, migration, and lung metastasis in vivo. Furthermore, SMC4 interacts with GLUT1 (Slc2a1), thereby enhancing glycolysis, ATP production, and activation of the Rheb/mTOR pathway.

3D‐Printed Titanium Trabecular Scaffolds with Sustained Release of Hypoxia‐Induced Exosomes for Dual‐Mimetic Bone Regeneration

Advanced Science, EarlyView.
This study presents 3D‐printed Ti‐6Al‐4V trabecular scaffolds combined with hypoxia‐induced exosomes encapsulated in PEGDA/GelMA microspheres for sustained release. The scaffolds mimic the structure of natural bone, while the exosome delivery system enhances osteogenesis and angiogenesis, significantly promoting bone regeneration and offering a ...
