Single-pass Kelvin force microscopy and dC/dZ measurements in the intermittent contact: applications to polymer materials

Beilstein Journal of Nanotechnology, 2011
We demonstrate that single-pass Kelvin force microscopy (KFM) and capacitance gradient (dC/dZ) measurements with force gradient detection of tip–sample electrostatic interactions can be performed in the intermittent contact regime in different ...

Analysis of tip stability in adhesion process in AFM using potential energy surface: Stability versus dissipation

, 2018
We analyze the stability of the atomic configurations of tips in the adhesion process in noncontact atomic force microscopy (AFM) using a potential energy surface (PES).

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

The dependence of the surface diffusion coefficients of gold atoms on the potential: its influence on reconstruction of metal lattices

, 1992
By using a method based on the time dependence of the surface roughness factor of electrodispersed gold electrodes it was possible to estimate values of the surface diffusion coefficients (Ds) of gold atoms in contact with an 1M HClO4 electrolytic ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular 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 ...

A Physically Based Relation Between Extracted Threshold Voltage and Surface Potential Flat-Band Voltage for MOSFET Compact Modeling

, 2001
Compact MOS models based on surface potential are now firmly established, but for practical applications there is no reliable link between measured values of threshold voltage and the flat-band voltage on which such models are based.

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

Molecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting
