Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

Association of normal-range fetal heart rate variations during labor with umbilical cord arterial blood gas parameters and neonatal outcomes: A cross-sectional study

International Journal of Reproductive BioMedicine
Background: Fetal heart rate (FHR) monitoring is a routine, non-invasive method for assessing fetal well-being during labor. However, its low sensitivity and high false-positive rate often lead to unnecessary cesarean deliveries. While fetal scalp blood

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

Advanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Sawtooth fetal heart rate pattern associated with a favorable neurological outcome in an infant: a case report

Journal of Medical Case Reports, 2019
Background The sawtooth fetal heart rate pattern is rare, and has been reported as a possible indicator of neurological sequelae in newborns. However, we observed this fetal heart rate pattern in an infant with normal neurological function.
