Inhibition of mTOR by rapamycin does not improve hypoxic pulmonary hypertension-induced right heart failure in old mice.

Exp Gerontol 2021 May 7:111395. Epub 2021 May 7.

Division of Kinesiology & Health, University of Wyoming, Laramie, WY, United States of America. Electronic address:

Inhibition of the mammalian target of rapamycin (mTOR) by rapamycin attenuates heart failure (HF) and age-associated changes in left ventricular (LV) function. Rapamycin has also been suggested as a therapy for pulmonary hypertension (PH) and concomitant right heart failure (PH-RHF) based on reports of elevated mTOR signaling in young models with PH. However, rapamycin has yet to be tested in the setting of aging, PH, and right heart disease despite the fact that RV function predicts survival in both age-related HF as well as several pulmonary disease states including PH.

Neuroscience 2021 May 7. Epub 2021 May 7.

Neuroplasticity and Movement Control Research Group, Rehabilitation Research Institute (REVAL), Hasselt University, Diepenbeek, Belgium; Movement Control and Neuroplasticity Research Group, Department of Movement Sciences, Group Biomedical Sciences, KU Leuven, Heverlee, Belgium. Electronic address:

Few studies have identified the intrahemispheric functional connectivity between the ipsilateral dorsal premotor cortex (PMd) and the primary motor hand area (M1) due to technical limitations. In this proof-of-concept study, a novel neuronavigated dsTMS set-up was employed, combining stimulation over left PMd and left M1 using the edge of a butterfly coil and a small cooled-coil. This arrangement was warranted because coil (over)heating and inter coil distance are limiting factors when investigating connectivity between stimulation targets in close proximity and over a longer duration.
