Differential Responses of Urinary Epinephrine and Norepinephrine to 24-h Shift-Work Stressor in Physicians

Frontiers in Endocrinology, 2020
Multiple stressors, including 24-h-shifts characterise the working environment of physicians, influencing well-being, health and performance. We aimed to evaluate the effect of the stressor 24-h-shift on the adrenal medullary and sympathoneural system in

Catecholamine stress alters neutrophil trafficking and impairs wound healing by β2-adrenergic receptor-mediated upregulation of IL-6. [PDF]

, 2014
Stress-induced hormones can alter the inflammatory response to tissue injury; however, the precise mechanism by which epinephrine influences inflammatory response and wound healing is not well defined.

Metformin Restores Mitochondrial Function and Neurogenesis in POLG Patient‐Derived Brain Organoids

Advanced Science, EarlyView.
Patient‐derived POLG‐mutant cortical organoids reveal neuronal subtype‐specific mitochondrial and synaptic defects, with dopaminergic neurons most affected. Metformin treatment restores neuronal identity, mitochondrial function, and excitability, increased mtDNA maintenance, and reprogrammed metabolism via TCA and redox pathways.

One‐Pot Incorporation of Quantum Defects into Single‐Walled Carbon Nanotubes with Arylazo Sulfonates

Angewandte Chemie, EarlyView.
We present a photochemical strategy to create complex aromatic quantum defects in carbon nanotubes using arylazo sulfonates. It provides access to brighter carbon nanotubes without purification and simpler biofunctionalization. Abstract Single‐walled carbon nanotubes (SWCNTs) consist of a carbon monolayer and fluoresce in the near‐infrared (NIR, 800 ...

Pharmacological Microglial Inhibition Remodels the Scar Microenvironment to Support Reticulospinal Circuit Reconstruction After Spinal Cord Injury

Advanced Science, EarlyView.
This study establishes pharmacological microglial inhibition as a therapeutic strategy, demonstrating its capacity to remodel the lesion microenvironment through significant reduction of extracellular matrix deposition. This permissive environmental transformation facilitates robust regeneration of the reticulospinal tract, and reconstructs functional ...
