Daily Doxycycline for Early Syphillis
Recruiting
The goal of this clinical trial is to learn if doxycycline taken as 200mg daily for 14 days is effective to treat early stage syphilis. This is different from how doxycycline is typically used for syphilis because the full doxycycline dose will be taken at the same time of day, rather than split up into a twice daily regimen. Lab data support that taking the medication as a single daily dose should be effective as treatment, but it has not been studied clinically. The main question this study ai... Read More

Hand and Arm Motor Recovery Via Non-invasive Electrical Spinal Cord Stimulation After Stroke
Recruiting
The recovery from a stroke is often incomplete. It is the leading cause of acquired permanent disability in the adult population. Persistent functional loss of the hand and arm contributes significantly to disability. However, the current standard of care to treat hand and arm movements are inadequate. There is an urgent need for innovative and effective therapies for recovery of the upper limb after stroke.
Growing evidence shows that electrical spinal cord stimulation, combined with activity-... Read More
