Numerical study of the depth and cross-sectional shape of tunnel under surface explosion
(Tunnelling and Underground Space Technology, 2015)Recently, blasting loads have come into consideration because of the large number of intentional or unintentional events that affected important structures around the world, obviously indicating that ... -
A hybrid approach to assess the structural impact of long noncoding RNA mutations uncovers key NEAT1 interactions in colorectal cancer
(IUBMB Life, 2023)Long noncoding RNAs (lncRNAs) are emerging players in cancer and they entail potential as prognostic biomarkers or therapeutic targets. Earlier studies have identified somatic mutations in lncRNAs that ... -
EvolClustDB: exploring eukaryotic gene clusters with evolutionarily conserved genomic neighbourhoods
(Journal of Molecular Biology, 2023)Conservation of gene neighbourhood over evolutionary distances is generally indicative of shared regulation or functional association among genes. This concept has been broadly exploited in prokaryotes ... -
Transcriptomic analyses reveal groups of co-expressed, syntenic lncRNAs in four species of the genus Caenorhabditis
(Taylor & Francis, 2019)Long non-coding RNAs (lncRNAs) are a heterogeneous class of genes that do not code for proteins. Since lncRNAs (or a fraction thereof) are expected to be functional, many efforts have been dedicated to ... -
Spatiotemporal network dynamics and structural correlates in the human cerebral cortex in vitro
(Progress in Neurobiology, 2025)Elucidating human cerebral cortex function is essential for understanding the physiological basis of both healthy and pathological brain states. We obtained extracellular local field potential recordings ... -
Neurophysiological signatures of prediction in language: A critical review of anticipatory negativities
(Neuroscience & Biobehavioral Reviews, 2024)Recent event-related potential (ERP) studies in language comprehension converge in finding anticipatory negativities preceding words or word segments that can be pre-activated based on either sentence ... -
Multisensory information facilitates reaction speed by enlarging activity difference between superior colliculus hemispheres in rats
(PLoS ONE, 2011)Animals can make faster behavioral responses to multisensory stimuli than to unisensory stimuli. The superior colliculus (SC), which receives multiple inputs from different sensory modalities, is ... -
Biological and cellular effects of percutaneous electrolysis: a systematic review
(Biomedicines, 2024)Background: Percutaneous electrolysis is an invasive physical therapy technique that is receiving attention. The objective of this article is to evaluate the biological and cellular effects of percutaneous ... -
Long-term expression of erythropoietin from myoblasts immobilized in biocompatible and neovascularized microcapsules
(Molecular Therapy, 2005)The present paper investigates the long-term functionality of an ex vivo gene therapy approach based on cell microencapsulation for the continuous delivery of erythropoietin (EPO) without implementation ... -
Electrophysiological correlates of semantic anticipation during speech comprehension
(Neuropsychologia, 2017)Words that are more predictable given a previous context show facilitated processing over low predictable ones. Such facilitation has been traditionally viewed as associated with reduced amplitudes in ... -
Middle Pleistocene teeth from Arbreda Cave (Serinyà, northeastern Iberian Peninsula)
(American Journal of Biological Anthropology, 2024)Objectives: We report the discovery and description of three human teeth from the Middle Paleolithic archaeological levels of Arbreda Cave (Serinyà, Catalonia, NE Iberian Peninsula). Materials and ... -
Principles of miRNA/miRNA* function in plant MIRNA processing
(Nucleic Acids Research, 2024)MicroRNAs (miRNAs) are essential regulators of gene expression, defined by their unique biogenesis, which requires the precise excision of the small RNA from an imperfect fold-back precursor. Unlike ... -
sincFold: end-to-end learning of short- and long-range interactions in RNA secondary structure
(Briefings in Bioinformatics, 2024)Motivation: Coding and noncoding RNA molecules participate in many important biological processes. Noncoding RNAs fold into well-defined secondary structures to exert their functions. However, the ... -
Probing RNA structural landscapes across Candida yeast genomes
(Frontiers in Microbiology, 2024)Understanding the intricate roles of RNA molecules in virulence and host-pathogen interactions can provide valuable insights into combatting infections and improving human health. Although much progress ... -
A progesterone derivative linked to a stable phospholipid activates breast cancer cell response without leaving the cell membrane
(Cellular and Molecular Life Sciences, 2024)In hormone-responsive breast cancer cells, progesterone (P4) has been shown to act via its nuclear receptor (nPR), a ligand-activated transcription factor. A small fraction of progesterone receptor is ... -

Dynamic force spectroscopy of DNA hairpins: II. Irreversibility and dissipation
(Journal of Statistical Mechanics: Theory and Experiment, 2009)We investigate irreversibility and dissipation in single molecules that cooperatively fold/unfold in a two-state manner under the action of mechanical force. We apply path thermodynamics to derive ... -
Dynamic force spectroscopy of DNA hairpins: I. Force kinetics and free energy landscapes
(Journal of Statistical Mechanics: Theory and Experiment, 2009)We investigate the thermodynamics and kinetics of DNA hairpins that fold/unfold under the action of applied mechanical force. We introduce the concept of the molecular free energy landscape and derive ... -
Work distributions in the T = 0 random field Ising model
(Physical Review E, 2008)We perform a numerical study of the three-dimensional random-field Ising model at T= 0. We compare work distributions along metastable trajectories obtained with the single-spin flip dynamics with the ... -
Investigating the thermodynamics of small biosystems with optical tweezers
