Direct Current Stimulation Of Endothelial Monolayers Induces A Transient And Reversible Increase In Transport Due To The Electroosmotic Effect, Limary M. Cancel, Katherin Arias, Marom Bikson, John M. Tarbell

Publications and Research

We investigated the effects of direct current stimulation (DCS) on fluid and solute transport across endothelial cell (EC) monolayers in vitro. Our motivation was transcranial direct current stimulation (tDCS) that has been investigated for treatment of neuropsychiatric disorders, to enhance neurorehabilitation, and to change cognition in healthy subjects. The mechanisms underlying this diversity of applications remain under investigation. To address the possible role of blood-brain barrier (BBB) changes during tDCS, we applied direct current to cultured EC monolayers in a specially designed chamber that generated spatially uniform direct current. DCS induced fluid and solute movement across EC layers that persisted …

Depressive Symptoms Are Associated With Cognitive Function In The Elderly With Type 2 Diabetes, Elizabeth Guerrero-Berroa, Ramit Ravona-Springer, James Schmeidler, Anthony Heymann, Laili Soleimani, Mary Sano, Derek Leroith, Rachel Preiss, Ruth Zukran, Jeremy M. Silverman, Michal Schnaider Beeri

Background: Type 2 diabetes (T2D) is a metabolic condition associated with poor clinical and cognitive outcomes including vascular disease, depressive symptoms, cognitive impairment, and dementia. In the general elderly population, depression has been consistently identified as a risk factor for cognitive impairment/decline. However, the association between depression and cognitive function in T2D has been understudied.

Objective: We investigated the association between depression and cognitive function in a large sample of cognitively normal elderly with T2D.

Methods: In this cross-sectional study, we examined 738 participants, aged 65–88 years old, enrolled in the Israel Diabetes and Cognitive Decline study. For each …
