Assessing the potential role of copper and cobalt in stimulating angiogenesis for tissue regeneration
(PLoS One, 2021)The use of copper (Cu2+) and cobalt (Co2+) has been described to stimulate blood vessel formation, a key process for the success of tissue regeneration. However, understanding how different concentrations ... -
ATP, Mg2+, nuclear phase separation, and genome accessibility
(Trends in Biochemical Sciences, 2019)Misregulation of the processes controlling eukaryotic gene expression can result in disease. Gene expression is influenced by the surrounding chromatin; hence the nuclear environment is also of vital ... -
CDKN1A/p21 in breast cancer: part of the problem, or part of the solution?
(International Journal of Molecular Sciences, 2023)Cyclin-dependent kinase inhibitor 1A (Cip1/Waf1/CDKN1A/p21) is a well-established protein, primarily recognised for its pivotal role in the cell cycle, where it induces cell cycle arrest by inhibiting ... -
Chronic full-band recordings with graphene microtransistors as neural interfaces for discrimination of brain states
(Nanoscale Horizons, 2024)Brain states such as sleep, anesthesia, wakefulness, or coma are characterized by specific patterns of cortical activity dynamics, from local circuits to full-brain emergent properties. We previously ... -
comTAR: a web tool for the prediction and characterization of conserved microRNA targets in plants
(Bioinformatics, 2014)Motivation: MicroRNAs (miRNAs) are major regulators of gene expression in plants and animals. They recognize their target messenger RNAs (mRNAs) by sequence complementarity and guide them to cleavage ... -
Correlation between physical performance and stabilometric parameters in older adults
(Medicina, 2022)Background and Objectives: Falls are a common and serious threat to the health and independence of older adults. The decrease in functional capacity during aging means an increased risk of falls. To ... -
Counter-propagating dual-trap optical tweezers based on linear momentum conservation
(Review of Scientific Instruments, 2013)We present a dual-trap optical tweezers setup which directly measures forces using linear momentum conservation. The setup uses a counter-propagating geometry, which allows momentum measurement on each ... -
Derivation of nearest-neighbor DNA parameters in magnesium from single molecule experiments
(Nucleic Acids Research, 2017)DNA hybridization is an essential molecular reaction in biology with many applications. The nearest-neighbor (NN) model for nucleic acids predicts DNA thermodynamics using energy values for the different ... -
Description of an ultrasound-guided transverse approach to the transversus thoracis plane block and evaluation of injectate spread in canine cadavers
(Animals, 2021)In humans, the aim of the transversus thoracis plane block is to desensitise the intercostal nerves running through this plane, providing analgesia to the anterior chest wall. Our objective was twofold: ... -
Differential effects of muscarinic receptor blockade in prelimbic cortex on acquisition and memory formation of an odor-reward task
(Learning Memory, 2007)The present experiments determined the consequences of blocking muscarinic cholinergic receptors of the prelimbic (PL) cortex in the acquisition and retention of an odor-reward associative task. Rats ... -
Dissociation of functional and structural plasticity of dendritic spines during NMDAR and mGluR-dependent long-term synaptic depression in wild-type and fragile X model mice
(Molecular Psychiatry, 2021)Many neurodevelopmental disorders are characterized by impaired functional synaptic plasticity and abnormal dendritic spine morphology, but little is known about how these are related. Previous work in ... -
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 ... -
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 ... -
Effectiveness of a multicomponent training program on physical performance and muscle quality in older adults: a quasi-experimental study
(International Journal of Environmental Research and Public Health, 2023)Aging is associated with a decrease in functional capacity, manifested by a loss of strength, physical performance and muscle quality. Multicomponent training (MCT), characterized by the combination of ... -
Effects of muscarinic receptor antagonism in the basolateral amygdala on two-way active avoidance
(Experimental Brain Research, 2011)The aim of the present study was to investigate whether the blockade of muscarinic receptors (mRs) in the basolateral amygdala (BLA), which receives important cholinergic inputs related to avoidance ... -
Efficiency and precision of microRNA biogenesis modes in plants
(Nucleic Acids Research, 2018)Many evolutionarily conserved microRNAs (miRNAs) in plants regulate transcription factors with key functions in development. Hence, mutations in the core components of the miRNA biogenesis machinery ... -
