Brain-derived neurotrophic factor/tropomyosin receptor kinase B signaling in promoting the differentiation and dentin-repair capacity of dental stem cells under inflammatory conditions offers a potential clinical strategy for repairing damaged teeth.
Exponential nucleic acid replication can occur isothermally in a prebiotically plausible setting that accumulates and simultaneously separates the strands of nucleic acids through evaporation-driven flows at the gas–water interface.
A single β-lactam exposure rapidly drives stable multidrug resistance in RecA-deficient bacteria through an SOS-independent mechanism involving oxidative stress-induced mutagenesis and antibiotic-driven selection.
