Molecular Regulation of Muscle Stem Cell Fate during Skeletal Muscle Regeneration and Aging

Sara Ancel

Muscle stem cells (MuSCs) are the primary source of myogenic progenitors during muscle repair and are essential for the long-term regenerative capacity of skeletal muscle. Following myofiber injury, MuSCs transition from a quiescent to an activated state, ...

Rhodanian Neighborhoods in Transition: Towards an Integrative Strategy Facilitating Decision-Making for New Sustainable Fluvio-Neighborhoods

Emmanuel Rey, Sara Sonia Formery Regazzoni, Martine Laprise

In the changing history of city-river relationships, cities are today questioning strategies for “reconciliation”. Thus, rather degraded sites like riverside brownfields represent an important potential for the creation of new sustainable fluvio-neighborho ...

The Links between ALS and NF-κB

Bernard Schneider, Brian Donal McCabe, Emma Charlotta Källstig

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease wherein motor neu-ron degeneration leads to muscle weakness, progressive paralysis, and death within 3–5 years ofdiagnosis. Currently, the cause of ALS is unknown but, as with several neuro ...

Cell Type-Specific Membrane Potential Changes in Dorsolateral Striatum Accompanying Reward-Based Sensorimotor Learning

Carl Petersen, Sylvain Crochet, Tanya C Sippy

The striatum integrates sensorimotor and motivational signals, likely playing a key role in reward-based learning of goal-directed behavior. However, cell type-specific mechanisms underlying reinforcement learning remain to be precisely determined. Here, w ...

Thermomechanical properties of honeycomb lattices from internal-coordinates potentials: the case of graphene and hexagonal boron nitride

Nicola Marzari, Francesco Libbi

Lattice dynamics in low-dimensional materials and, in particular, the quadratic behaviour of the flexural acoustic modes play a fundamental role in their thermomechanical properties. A first-principles evaluation of these can be very demanding, and can be ...

Switchable wetting of oxygen-evolving oxide catalysts

Vasiliki Tileli, Tzu-Hsien Shen

The surface wettability of catalysts is typically controlled via surface treatments that promote catalytic performance. Here we report on potential-regulated hydrophobicity/hydrophilicity at cobalt-based oxide interfaces with an alkaline solution. The swit ...

Transport signatures of temperature-induced chemical potential shift and Lifshitz transition in layered type-II Weyl semimetal TaIrTe4

Oleg Yazyev, Quansheng Wu, Meng Yang

Temperature-induced Lifshitz transitions have been identified in several materials. Their chemical potential shows a substantial shift with changing temperature. The common feature of these materials is the coexistence of electron and hole pockets in the v ...

Effect of illumination and applied potential on the electrochemical impedance spectra in triple cation (FA/MA/Cs) 3D and 2D/3D perovskite solar cells

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Zubair Ahmad

Even though there has been numerous works performed based on electrochemical impedance spectroscopy (EIS) of perovskite solar cells (PSCs), however, many aspects of the obtained EI spectra are yet to be fully grasped. Moreover, the change of these spectra ...

The role of medial amygdala inhibitory neurons in regulating social behavior

Aiste Baleisyte

Aggression is an evolutionary conserved social behavior that is necessary for an animalÂŽs survival. The neural substrates coordinating aggression are known to exist in the amygdala and the hypothalamus. While the medial amygdala (MeA) and the ventrolatera ...

Breathing is coupled with voluntary action and the cortical readiness potential

Olaf Blanke, Oliver Alan Kannape, Coline Barnoud, Hyeongdong Park, Henri Dan Trang

Voluntary action is a fundamental element of self-consciousness. The readiness potential (RP), a slow drift of neural activity preceding self-initiated movement, has been suggested to reflect neural processes underlying the preparation of voluntary action; ...

GABA-mediated tonic inhibition differentially modulates gain in functional subtypes of cortical interneurons

Sean Lewis Hill, Christian Andreas Rössert, Bas-Jan Zandt, Steven Petrou

The binding of GABA (gamma-aminobutyric acid) to extrasynaptic GABA(A) receptors generates tonic inhibition that acts as a powerful modulator of cortical network activity. Despite GABA being present throughout the extracellular space of the brain, previous ...

Cortical reliability amid noise and chaos

Henry Markram, James Gonzalo King, Eilif Benjamin Muller, Michael Reimann, Max Christian Nolte

Typical responses of cortical neurons to identical sensory stimuli appear highly variable. It has thus been proposed that the cortex primarily uses a rate code. However, other studies have argued for spike-time coding under certain conditions. The potentia ...
