From 2D to 3D Bioprinted In Vitro Breast Cancer Model: A Comparative Study of Proliferation, Tissue Structure, and mTOR Signaling

MedComm, Volume 7, Issue 6, June 2026.
A 3D bioprinted breast cancer model was created to more accurately reproduce in vivo tumor characteristics compared to conventional 2D cultures. Distinct cell adhesion patterns, reduced mTOR signaling, and altered drug responses were observed under 3D conditions.

A Passive Low‐Frequency, High‐Sensitivity Diamagnetic Levitation Accelerometer

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 344-356, June 2026.
ABSTRACT Despite the great potential of diamagnetic levitation accelerometers in detecting low‐frequency and weak motion, there is still a demand to further enhance their sensitivity for geophysical and microgravity applications. In this study, a straightforward structural modulating approach is presented to enhance the sensitivity of diamagnetic ...

Oxygen Doping and Crystal–Amorphous Multiphase Coupling Synergistically Improve the Wear Resistance of NiTiCu Alloy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT NiTi shape memory alloys (SMAs) show excellent performance in vibration damping and corrosion resistance. However, due to low hardness and lack of self‐lubrication, they suffer severe friction and wear during service. Although various strategies including doping and heterostructure design have been proposed, the effects are unsatisfactory.

Does Gastrointestinal Bleeding Increase the Risk of Thromboembolic Events in Patients Supported With CF‐LVADs?

Artificial Organs, Volume 50, Issue 6, Page 886-890, June 2026.
Gastrointestinal bleeding significantly increases thromboembolic risk. Higher risk was also seen in patients aged ≥ 50 years, Black patients, and those with older CF‐LVAD models. ABSTRACT Background Gastrointestinal bleeding is a common complication in continuous‐flow left ventricular assist device (CF‐LVAD) patients. Managing gastrointestinal bleeding

Predictors of Brain Infarction in Pediatric Patients During Extracorporeal Membrane Oxygenation

Artificial Organs, Volume 50, Issue 6, Page 909-916, June 2026.
In 179 pediatric ECMO patients, brain infarction (BI) occurred in 28% and was linked to markedly higher 30‐day mortality. VA ECMO mode (vs. VV) and higher pre‐ECMO arterial lactate independently predicted BI, supporting standardized neuro‐monitoring and liberal early brain CT, especially for children on VA ECMO.
