Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Study on Control Technology of Non-metallic Inclusions in 25MnBM Steel for Track Plate

open access: yesTeshugang, 2020
The 25MnBM track plate steel is produced by 50 ton EAF short process. The control technology of TiN inclusions and the effect of RE on non-metallic inclusions in 25MnBM of steel are studied.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Modification of Non-Metallic Inclusions in Stainless Steel by Addition of CaSi

open access: yesMetals, 2019
The focus of this study involved comparative investigations of non-metallic inclusions in 316L stainless steel bars without and with Ca treatments. The inclusions were extracted by using electrolytic extraction (EE).

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Non-metallic inclusions and plasticity of steels

open access: yes, 2020
The problems of the influence of non-metallic inclusions in the technological plasticity and mechanical properties of steels are discussed. The results of the study of deformation and destruction of non-metallic inclusions in steel treatment pressure in various conditions were listed.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

New insights of heterogeneous nucleation and anisotropic growth of acicular ferrite on non-metallic inclusion

open access: yesMaterials & Design, 2022
This work studies the acicular ferrite (AF) nucleation and growth from a classical defect, i.e. non-metallic inclusion surface. The heterogeneous AF-nucleation probability on NMI is predicted by a mathematical model following the classical nucleation ...
