Dynamic control of visually guided locomotion through corticosubthalamic projections.

Goal-directed locomotion requires control signals that propagate from higher order areas to regulate spinal mechanisms. The corticosubthalamic hyperdirect pathway offers a short route for cortical information to reach locomotor centers in the brainstem. We developed a task in which head-fixed mice run to a visual landmark and then stop and wait to collect the reward and examined the role of secondary motor cortex (M2) projections to the subthalamic nucleus (STN) in controlling locomotion.

Serum HE4 Level as a Biomarker to Predict the Recurrence of Gynecologic Cancers.

Background: HE4 may be a valuable early indicator of the recurrence of gynecologic cancers. Numerous studies have shown that high expression levels of serum HE4 correlate with ovarian and endometrial cancer recurrence. High HE4 levels may be an independent factor to predict these cancers' poor prognosis.
