Competition between Intra and Intermolecular Triel Bonds. Complexes between Naphthalene Derivatives and Neutral or Anionic Lewis Bases

Molecules, 2020
: A TrF2 group (Tr = B, Al, Ga, In, Tl) is placed on one of the α positions of naphthalene, and its ability to engage in a triel bond (TrB) with a weak (NCH) and strong (NC−) nucleophile is assessed by ab initio calculations.

Predictive value of motor-evoked potentials for motor recovery in patients with hemiparesis secondary to acute ischemic stroke

Annals of Medicine, 2023
Background Motor recovery following a stroke is related to the initial stroke severity and corticospinal tract integrity. One of the outcomes representing corticospinal tract integrity is the motor evoked potential (MEP).

Usefulness of Transcranial Motor Evoked Potential in Clipping Surgery for Cerebral Aneurysms―Introduction of a New Protocol for Stable Monitoring

Neurologia Medico-Chirurgica, 2023
The usefulness of transcranial motor evoked potentials (Tc-MEPs) in clipping surgery has been reported. However, numerous false positive and false negative cases were reported. We report the usefulness of a new protocol compared with direct cortical MEP (
