A Role for the Cytoskeleton in Heart Looping by Kersti K. Linask, Michael VanAuker

“…The cytoskeleton is associated with important mechanosensing and signaling pathways in cell biology and development. The initiation of blood flow during the looping period and the inherent stresses associated with increasing volumes of blood flowing into the heart may help to potentiate the process. …”

MRI Findings of Causalgia of the Lower Extremity Following Transsphenoidal Resection of Pituitary Tumor by D. Ryan Ormond, Augustine L. Moscatello, Raj Murali

“…Causalgia is continuing pain, allodynia, or hyperalgesia after nerve injury with edema, changes in skin blood flow, or abnormal sudomotor activity. Here we report a case of lower extremity causalgia following elective transsphenoidal resection of a pituitary tumor in a young man. …”
