A second vestigial umbilical vein : a case report [PDF]

open access: yes, 2009
A healthy female infant was found to have two umbilical arteries and two umbilical veins at the cut surface of the cord at birth. Detailed inspection of the cord showed the second vein to represent a short segment vestigial vessel that, moreover, was not

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

open access: yesAdvanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...

Multimodal Investigation of Angiogenesis and Its Prevention by Small Compounds in a Zebrafish Cancer Model

open access: yesAdvanced Science, EarlyView.
A combined optical coherence tomography angiography and fluorescence imaging approach assesses tumor angiogenesis and drug effects in a novel zebrafish cancer model. By analyzing 3D vasculature data, the two imaging methods complement each other to quantify blood flow, vessel structure, and drug efficacy.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

open access: yesAdvanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

Microphysiological Uremia Model Reveals Biophysical Potentiators of Vascular Dysfunction

open access: yesAdvanced Science, EarlyView.
A microfluidic platform of engineered blood vessels is developed to study the role of mechanical forces in immune cell adhesion and extravasation in uremic microenvironments. Elevated pressure increases monocyte activity, with ICAM‐1 as a key driver. Matrix density influences monocyte phenotypes, but the uremic environment consistently promoted a pro ...

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

open access: yesAdvanced 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 ...

High‐Efficiency Carriers’ Separation Strategy Based Ultrasmall‐Bandgap CuWO4 Sono‐Enhances GSH Antagonism for Cuproptosis Cascade Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study prepares copper tungstate (CuWO4, CWO) nanoparticles for synergistic sono‐enhanced cuproptosis‐based cancer therapy. With an ultrasmall bandgap (1.71 eV), CWO facilitates efficient charge carrier separation under ultrasound, enhancing the generation of reactive oxygen species and the controlled release of Cu2+ ions cascade amplify oxidative ...
