Positive effects of pre-oxidation on high temperature oxidation behavior of TiAl composites with multilayered structure

Journal of Materials Research and Technology
In order to study the pre-oxidation on high temperature oxidation behavior of TiAl composites with high-efficiency, the TiAl composites with multilayered structure were successfully prepared via spark plasma sintering (SPS) by introducing 0.5 wt% BN, 0.5

Constitutive equation and microstructure evolution of TiAl alloy during hot deformation

Materials Research Express, 2023
The hot deformation behavior of TiAl alloy is analyzed by combining the true stress–strain curve and microstructure analysis. The results show that the flow stress of TiAl alloy presents the characteristics of work hardening-dynamic softening, it ...

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

Molecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

Molecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.
