Feasibility of Virtual Research Visits in Fox Trial Finder.

Background: Fox Trial Finder is an online registry for individuals with and without Parkinson disease (PD) interested in participating in PD research. However, distance or disability could prevent such individuals from participating in traditional, clinic-based research at major centers.

Objective: Use videoconferencing to connect participants to specialists to: (1) demonstrate feasibility of virtual research visits within this population (2) collect phenotypic data of the participants, (3) validate self-reported diagnosis, and (4) gauge interest in virtual research visits.

Managing depression in Parkinson's patients: risk factors and clinical pearls.

Parkinson's disease (PD) is a neurodegenerative condition that is on the rise as the world's population ages. As our understanding of the disease increases, depression has emerged as a common syndrome in this population that significantly reduces quality of life, making its understanding, recognition and treatment an important area of focus for clinicians and researchers alike. It is hypothesized that depression is a consequence of the disease process itself, sometimes developing prior to the onset of motor symptoms.

Continuously measured renal blood flow does not increase in diabetes if nitric oxide synthesis is blocked.

This study used 16 h/day measurement of renal blood flow (RBF) and arterial pressure (AP) to determine the role of nitric oxide (NO) in mediating the renal vasodilation caused by onset of type 1 diabetes. The AP and RBF power spectra were used to determine the autoregulatory efficiency of the renal vasculature. Rats were instrumented with artery and vein catheters and a Transonic flow probe on the left renal artery and were divided randomly into four groups: control (C), diabetes (D), control plus nitro-L-arginine methyl ester (L-NAME; CL), and diabetes plus L-NAME (DL).
