Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

A New Fully Soft‐Switching High Step‐Up Interleaved Converter for Optimal Efficiency

IET Power Electronics
A novel fully soft‐switching interleaved high step‐up converter is introduced in this paper. The suggested converter achieves high voltage gain using coupled inductors (CI) and a voltage multiplier cell (VMC).

Analysis of Switching-Loss-Reduction Methods for MHz-Switching Buck Converters [PDF]

2007 IEEE Conference on Electron Devices and Solid-State Circuits, 2007
Numbers of switching-loss-reduction methods recently proposed for MHz-switching buck converters are thoroughly investigated. From a theoretical perspective, switching loss is found to be effectively minimized by adapting the width rather than the turn-on voltage of power transistors of a buck converter.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Abrupt turn-on and hysteresis in a VCSEL with frequency-selective optical feedback [PDF]

, 2006
The emission characteristics of a vertical-cavity surface-emitting laser (VCSEL) operated in a single-transverse mode and coupled to an external cavity with a diffraction grating as a frequency-selective element are analyzed experimentally, numerically ...

Low-loss AlInN/GaN microwave switch

Electronics Letters, 2011
A report is presented on the first low-loss monolithic microwave integrated circuit switch using AlInN/GaN heterostructure field effect transistors. Owing to significantly lower sheet resistance compared to the conventional AlGaN/GaN heterostructure (215 against 280 Q/□), and lower contact resistance (0.27 against 0.5 Ω×mm), the microwave switch based ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
