Feedback control for deep brain stimulation for motor disorders

Healthcare Technology Letters, 2020
Deep brain stimulation (DBS) is an effective treatment for many people living with Parkinson's disease (PD). Although the primary treatment for PD is based on medications, disease progression eventually leads to inadequate symptom control.

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

Advanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.
