Liquid Metal Sensors for Soft Robots

open access: yesAdvanced Robotics Research, EarlyView.
This review thoroughly reviews liquid metal sensors in soft robots. Their unique material properties like high conductivity and good biocompatibility are analyzed. Working principles are classified, and applications in environmental perception, motion detection, and human—robot interaction are introduced.

Optimizing the labyrinth geometric parameters and modelling a new twin seal configuration for improved sealing efficiency in gas turbines

open access: yesFrontiers in Mechanical Engineering
Labyrinth seals are the non-contact seals used in turbo machinery to control the leakage of the secondary fluid flow. The main compressor supplies the compressed air required to generate hot gases in the combustion chamber.

Intralabyrinthine Penetrating Ventilation Tube with Preservation of Hearing: An Unusual Clinical Situation

open access: yesInternational Archives of Otorhinolaryngology, 2015
Introduction Traumatic perilymphatic fistula is not a rare event with regards to sport activities or traffic accident. However, iatrogenic damage to the inner ear can occur following the common use of grommets and ventilation tube insertion.

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

open access: yesAdvanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

Long‐Term Memory Updating Parallels Altered Awake and Sleep Hippocampal Replays

open access: yesAdvanced Science, EarlyView.
This study introduces a behavioral paradigm for memory updating and reveals underlying hippocampal mechanisms. Replays of place cells predict future behavioral choices during behavior and show a bias toward high‐reward locations during non‐rapid eye movement (NREM) sleep, specifically within the memory updating process.

ATF5‐Dependent GDF15 Expression Mediates Anesthesia‐Induced Neuroprotection Against Stroke

open access: yesAdvanced Science, EarlyView.
Anesthesia‐induced preconditioning protects against perioperative stroke. By manipulating ATF5 in excitatory neurons, it is shown that anesthesia‐driven ATF5 upregulation activates the mitochondrial unfolded protein response (UPRmt) and elevates GDF15 expression.

Inhibiting Liver‐Derived C3 Protein Rescues Anesthesia/Surgery‐Induced Cognitive Impairment, Synaptic Disorders, and Microglial Phagocytosis

open access: yesAdvanced Science, EarlyView.
This study provides evidence that anesthesia/surgery can induce the BBB breakdown and promote the release of hepatogenous C3 protein into the blood. This surgical dual factors ultimately drove C3 to cross the damaged BBB and selectively colocalize with C3aR in the hippocampus, which results in structural and functional injury of synapse, C3aR‐mediated ...

Realgar‐Induced CNS Toxicity: Exploring OTC‐Mediated Ornithine Regulation of ZBTB7A Inhibits Astrocyte Glycolysis Based on the Liver–Brain Axis

open access: yesAdvanced Science, EarlyView.
Arsenic in realgar induces CNS toxicity through direct and indirect effects: it activates ZBTB7A in astrocytes, which in turn inhibits glycolysis and impairs mice's learning, memory, and exploration; it also suppresses OTC in the liver to block the ornithine cycle, leading to blood ornithine accumulation that crosses into the frontal lobe and further ...
