Article Synopsis
  • The management of pressure sores has been impacted by the COVID-19 pandemic, affecting both treatment methods and outcomes for patients.
  • A study evaluated the pressure sore characteristics in patients with COVID-19 compared to a control group, revealing that while the severity of pressure sores was similar, patients in isolation had fewer Grade I sores but more overall lesions.
  • Additionally, the COVID-19 isolation group experienced a higher mortality rate and a greater number of unhealed wounds upon discharge, indicating a need for improved wound care strategies for these patients.

Nerve growth factor (NGF) monoclonal antibodies inhibit chronic pain yet failed to gain approval due to worsened joint damage in osteoarthritis patients. We report that neuropilin-1 (NRP1) is a co-receptor for NGF and tropomyosin-related kinase A (TrkA) pain signaling. NRP1 was coexpressed with TrkA in human and mouse nociceptors.

Non-volatile memristors dynamically switch between high (HRS) and low resistance states (LRS) in response to electrical stimuli, essential for electronic memories, neuromorphic computing, and artificial intelligence. High-entropy Prussian blue analogs (HE-PBAs) are promising insertion-type battery materials due to their diverse composition, high structural integrity, and favorable ionic conductivity. This work proposes a non-volatile, bipolar memristor based on HE-PBA.

Article Synopsis
  • Near-rigid-body grain rotation is significant during processes like grain growth, recrystallization, and plastic deformation in nanocrystalline materials, but its mechanisms have been unclear for decades.
  • New evidence shows that grain rotation happens due to the movement of disconnections along grain boundaries in platinum thin films.
  • Advanced microscopy techniques reveal a statistical link between grain rotation and changes in grain size, highlighting the role of shear-coupled grain boundary migration in this phenomenon.
