Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

DESIGNING AND DEVELOPING A PROGRAM IN SINUMERIK vs. 1.3 FOR A SHAFT WITH SEALING GROOVES [PDF]

open access: yesFiabilitate şi Durabilitate, 2015
CNC is an abbreviation for „Computer Numerically Controlled". Numerically controlled tool machines are also called CNC machines.The numeric control results in a process of continuous „feeding” of an especially built programable controller, with a set ...

The effect of an organic pentasulfide EP additive in turning and milling operations [PDF]

open access: yes, 2014
Coopération avec Ecole Centrale LyonBecause a cutting fluid could be equally used for different cutting operations, this study proposed to investigate the behavior of a well-known extreme-pressure additive (pentasulfide) in both turning and milling ...

Laser Prepared Cutting Tools [PDF]

open access: yesPhysics Procedia, 2012
AbstractLaser pulses with a pulsewidth of a few picoseconds have recently received a lot of attention, solving the problem of manufacturing tools for new materials of superior mechanical properties. Processing thermally sensitive material, such as diamond and CBN structures, can be done without major material deterioration effects.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Machinability improvement using high-pressure cooling in turning

open access: yesResearch in Agricultural Engineering, 2014
Process fluids are used primarily for their cooling and lubricating effect in machining. Many ways to improve their performance have been proposed; the analysis of some of them is provided in the paper.

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Chaotic vibrations in a regenerative cutting process

open access: yes, 2001
We have analyzed vibrations generated in an orthogonal cutting process. Using a simple one degree of freedom model of the regenerative cutting we have observed the complex behaviour of the system.
