MicroRNAs: Pleiotropic Regulators in the Tumor Microenvironment

open access: yesFrontiers in Immunology, 2018
MicroRNAs (miRNAs) are small non-coding RNAs that typically inhibit the translation and stability of messenger RNAs (mRNAs). They are ~22 nucleotides long and control both physiological and pathological processes.

Abscisic Acid Regulates Auxin Homeostasis in Rice Root Tips to Promote Root Hair Elongation

open access: yesFrontiers in Plant Science, 2017
Abscisic acid (ABA) plays an essential role in root hair elongation in plants, but the regulatory mechanism remains to be elucidated. In this study, we found that exogenous ABA can promote rice root hair elongation. Transgenic rice overexpressing SAPK10 (

Ethylene and metal stress: small molecule, big impact

open access: yesFrontiers in Plant Science, 2016
The phytohormone ethylene is known to mediate a diverse array of signaling processes during abiotic stress in plants. Whereas many reports have demonstrated enhanced ethylene production in metal-exposed plants, the underlying molecular mechanisms are ...

Optimisation of the Protocol for the LIVE/DEAD® BacLightTM Bacterial Viability Kit for Rapid Determination of Bacterial Load

open access: yesFrontiers in Microbiology, 2019
Rapid antimicrobial susceptibility testing is needed to reduce prescription of inappropriate antibiotics. A rapid alternative to standard culture-based testing is to determine reductions in cell viability using the LIVE/DEAD® BacLightTM Bacterial ...

New Values of Cross-Talk Parameters for Twisted Pair Model

open access: yesAdvances in Electrical and Electronic Engineering, 2010
Near-end Crosstalk (NEXT) and Far-end Crosstalk (FEXT) of unshielded twisted pair (UTP) cable are the main factors limiting the information capacity in data transmission. Crosstalk depends mostly on the frequency.

Activation of Human NK Cells by Bordetella pertussis Requires Inflammasome Activation in Macrophages

open access: yesFrontiers in Immunology, 2019
Pertussis is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. Humans are the only known natural reservoir of B. pertussis. In mice, macrophages and NK cells have a key role in confining B.

An Improved Zero Potential Circuit for Readout of a Two-Dimensional Resistive Sensor Array

open access: yesSensors, 2016
With one operational amplifier (op-amp) in negative feedback, the traditional zero potential circuit could access one element in the two-dimensional (2-D) resistive sensor array with the shared row-column fashion but it suffered from the crosstalk ...
