Anisotropic Masked Mycobacterium Potentiates Amplified Antitumor Trained Immunity via Spleen Targeting and Myelopoiesis Conversion

Advanced Materials, EarlyView.
An engineered Trojan Mycobacterium, developed via a “peeling‐off and masking‐up” strategy, functions as a powerful splenic myelopoiesis converter. This spleen‐targeted nanomedicine induces trained immunity to reprogram immunosuppressive myeloid reservoirs into antitumoral effectors.

Stockpiling Ventilators for Influenza Pandemics

, 2017
In preparing for influenza pandemics, public health agencies stockpile critical medical resources. Determining appropriate quantities and locations for such resources can be challenging, given the considerable uncertainty in the timing and severity of ...

Spatial‐Compatibility‐Assisted Molecular Intercalation in MXenes

Advanced Materials, EarlyView.
This work demonstrates a solvent–free NH4F–mediated route for simultaneous Al removal and molecular intercalation in MXenes. Intercalants are selected by comparing their crystallographic X, Y, and Z dimensions with the MXene interlayer spacing, establishing a spatial‐compatibility criterion that rationalizes guest–host matching and enables predictive ...

Performance assessment of a ventilator developed for emergency use in a resource-constrained ICU setting during the COVID-19 pandemic

BioMedical Engineering OnLine
Background The Masi mechanical ventilator was developed in Peru, designed and manufactured as a rapid-response to the healthcare emergency. Its promising pre-clinical and clinical results allowed it to be approved by the national regulatory authority to ...

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Morphological Characterization of Spherulites in Silk‐Polycaprolactone Mixtures: Implications for Textured Materials

Advanced Materials Interfaces, EarlyView.
Blending silk fibroin with polycaprolactone alters crystalline organization and surface morphology. Low fibroin levels promote ring‐banded spherulites, while higher contents generate porous, pit‐like textures, though overall crystallinity remains unchanged. Solvent evaporation further modulates surface patterns.

BAP31 Drives Cartilage Calcification through Disruption of Autophagosome–Lysosome Fusion in Osteoarthritis

Advanced Science, EarlyView.
Mechanical stress activates BAP31 in chondrocytes. BAP31 competes with ATG14 for binding to STX17, disrupting the STX17–ATG14 complex required for autophagosome–lysosome fusion. The resultant autophagic flux blockade drives the generation of autophagy‐derived exosomes, which mediate pathological cartilage calcification in OA. Chondrocyte‐targeted BAP31

Automatic ventilators

, 2016
Automatic ventilators enable the provision of intermittent positive pressure ventilation (IPPV) to support ventilation in anaesthetized or heavily sedated patients. An automatic ventilator is an invaluable tool that provides repeated, controlled breaths,
