Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

The club of the discontents: motivational roots, polarise narratives, and key actors of Spanish-speaking anti-abortion communities on Twitter

open access: yesHumanities & Social Sciences Communications
Amidst the evolving landscape of abortion laws in Latin America and Spain, the ethical discourse surrounding its acceptability remains highly contentious, particularly within digital advocacy campaigns aimed at its prohibition.

Colloquy with Steven Van de Walle on trust in Public Administration

open access: yesChurch, Communication and Culture, 2020
This interview with Professor Steven Van de Walle was framed by the fact that it was conducted during the lockdown caused by COVID-19, a crisis that has shown a globally shared vulnerability and that might be challenging the trustworthiness of ...

Partisanship, Ideology, and Selective Exposure: A Longitudinal Analysis of Media Consumption in Spain (2008–2019)

open access: yesMedia and Communication, 2023
The literature on selective exposure has shown that ideology and voting govern media consumption decisions, but longitudinal studies are still scarce.

A Mathematical Theory of Communication

open access: yesBell System Technical Journal, 1948
In this final installment of the paper we consider the case where the signals or the messages or both are continuously variable, in contrast with the discrete nature assumed until now. To a considerable extent the continuous case can be obtained through a limiting process from the discrete case by dividing the continuum of messages and signals into a ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Learned Block Iterative Shrinkage Thresholding Algorithm for Photothermal Super Resolution Imaging

open access: yesSensors, 2022
Block-sparse regularization is already well known in active thermal imaging and is used for multiple-measurement-based inverse problems. The main bottleneck of this method is the choice of regularization parameters which differs for each experiment.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

open access: yesMolecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Chaos communication performance : theory and computation [PDF]

open access: yes, 2010
In this paper new and existing approaches are developed to compute the bit error rate for chaos-based communication systems. The multi-user coherent antipodal chaos shift keying system is studied and evaluated in its coherent form, in the sense of ...
