Improved corrosion resistance and biocompatibility of biomedical magnesium alloy with polypeptide TK14 functionalised hydrophobic coating

Biosurface and Biotribology, 2021
Magnesium (Mg) and its alloys can be used as biomedical materials because of their excellent mechanical properties and biocompatibility. However, the rapid degradation rate of Mg‐based materials limits their application in biodegradable intravascular ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Flexible, high‐strength titanium nanowire for scaffold biomimetic periodontal membrane

Biosurface and Biotribology, 2021
A layer of micro‐sized periodontal membrane can buffer most chewing forces to protect the interface between the natural tooth root and alveolar bone. Artificial dental implants usually direct contact onto the alveolar bone without a buffer layer, which ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Copper‐mediated polyurethane materials with enzyme‐like catalysis for biocompatibility improvement in blood environments

Biosurface and Biotribology, 2021
Because of their good performance, including biocompatibility and mechanical properties, polyurethanes (PUs) are widely used in medical devices. However, undesired compatibility troubles, including thrombus, inflammation, and hyperplasia, still limit the

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...
