The cooperative regulation of miR‐221 by APE1 and AUF1 impacts p27Kip1 defining a miR signature relevant for cervical cancer

open access: yesFEBS Open Bio, EarlyView.
A regulatory axis involving APE1, AUF1, and miR‐221 is proposed. Pri‐miR‐221 is processed by DROSHA and DICER to generate mature miR‐221, which targets p27Kip1 mRNA. APE1 and AUF1 compete for pre‐miR‐221 binding. Reduced APE1/AUF1 levels impair miR‐221 biogenesis, decrease p27Kip1 mRNA degradation, and promote cell cycle progression, chemoresistance ...

Secure and Efficient Authentication Protocol for Underwater Wireless Sensor Network Environments Using PUF

open access: yesApplied Sciences
Underwater wireless sensor networks (UWSNs) are increasingly used in marine monitoring and naval coastal surveillance, where limited bandwidth, long propagation delays, and physically exposed nodes make efficient authentication critical.

PAAS: PMIPv6 Access Authentication Scheme Based on Identity-Based Signature in VANETs

open access: yesIEEE Access, 2018
Due to the advantages of low handover latency and signaling costs, Proxy Mobile IPv6 (PMIPv6), as a localized mobility management protocol for next generation mobile network, can be well combined with vehicular ad-hoc networks.

Identification of functional murine mitochondrial formyl peptides and their effects on myeloid‐derived suppressor cell generation

open access: yesFEBS Open Bio, EarlyView.
We first identified functional murine mitochondrial N‐formyl peptides (MT‐FPs) and investigated their effects on the in vitro myeloid‐derived suppressor cell (MDSC) generation from bone marrow cells. We demonstrated that MT‐FPs acted directly on bone marrow cells to promote MDSC generation and modulated the polymorphonuclear (PMN)‐MDSC/monocyte (M ...

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Beamsteering and Beamshaping Using a Linear Antenna Array Based on Particle Swarm Optimization

open access: yesIEEE Access, 2019
This paper discusses the architecture of an adaptive transmitting microstrip array that allows highly flexible beamsteering and beamshaping. The antenna array is digitally controlled by a field programmable gate array (FPGA) board. The power and phase of

Theoretical and Practical Assessments of Transfer Prices. Legal Evidence from Romanian Case Law

open access: yesJournal of Legal Studies, 2020
Transfer pricing represents the mainstream agenda in the light of tax law, lato sensu, and international taxation, stricto sensu. At the international level, there can be an emphasis on several problems related to taxation: double taxation, double non ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Non-trivial Supersymmetry Correlations between ATLAS and CMS Observations

open access: yes, 2012
We present definite correlations between the CMS 5 \fb all-hadronic search employing the stransverse mass variable $M_{T2}$ and the ATLAS 5 \fb all-hadronic and multijet supersymmetry (SUSY) searches, suggesting the possibility that both the ATLAS and ...
