Electron to Muon Conversion in Low-Energy Electron-Nucleus Scattering

open access: yes, 2004
We present an estimate of the electron to muon conversion cross section in fixed-target elastic electron scattering. The matrix element $$ is calculated analytically in two scenarios introducing suitable approximations.

Molecular determinants of signal transduction in tropomyosin receptor kinases

open access: yesFEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...
