The role of EGFR mutation as a prognostic factor in survival after diagnosis of brain metastasis in non-small cell lung cancer: A systematic review and meta-analysis [PDF]

open access: yes, 2019
Background The brain is a common site for metastasis in non-small-cell lung cancer (NSCLC). This study was designed to evaluate the relationship between the mutational of the epidermal growth factor receptor (EGFR) and overall survival (OS) in NSCLC ...

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

open access: yesMolecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Measurements of composite Skyrmions at filling factor

open access: yesPhysica B: Condensed Matter, 1998
Measurements of the fractional quantum Hall effect energy gaps at high pressures are presented that provide evidence for the existence of composite Skyrmions. Just as charged spin textures known as Skyrmions are thought to be the lowest lying excitations for electrons at v = 1, we show that composite Skyrmions can be formed at v = 1/3 when the electron

The low filling factor of dust in the Galaxy

open access: yesThe Astrophysical Journal, 1992
The neighborhood of 745 luminous stars in the IRAS Skyflux plates was examined for the presence of dust heated by the nearby star. One-hundred twenty-three dust clouds were found around only 106 of the stars with a volume filling factor of 0.006 and an intercloud separation of 46 pc.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Fabrication and Characterization of Tungsten-Modified TiO2 as a Photo-Anode in a Dye-Sensitized Solar Cell

open access: yesEngineering Proceedings
The tungsten (W)-modified TiO2 films were fabricated on the fluorine-doped TiO2 substrates using the sol–gel process. The influences of W dopant on the photovoltaic properties of the tungsten-modified TiO2 DSSC were analyzed, too. The crystallization and

Enhancing the fill-factor of CMOS SPAD arrays using microlens integration [PDF]

open access: yes, 2015
Arrays of single-photon avalanche diode (SPAD) detectors were fabricated, using a 0.35 μm CMOS technology process, for use in applications such as time-of-flight 3D ranging and microscopy.

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

New high fill-factor triangular micro-lens array fabrication method using UV proximity printing [PDF]

open access: yes, 2008
A simple and effective method to fabricate a high fill-factor triangular microlens array using the proximity printing in lithography process is reported. The technology utilizes the UV proximity printing by controlling a printing gap between the mask and
