Sympathetic nervous system disorder

This study gave a radioactive drug called 131I-MIBG to 15 people with advanced nerve tumors (neuroblastoma or pheochromocytoma) that had stopped responding to standard treatments. The goal was to see if it could ease symptoms and shrink tumors, while tracking side effects. Partic…

This study looks at how the body's stress (sympathetic) nervous system changes after 8 weeks of either strength training alone or strength training combined with running. Researchers measure nerve activity, muscle strength, and jumping ability in healthy young men who have not ex…

This study looked at whether a patient's abdominal circumference (belly size) is linked to how long surgery takes to remove a pheochromocytoma, a rare adrenal tumor. Researchers reviewed records of 159 adults who had the surgery. The goal was to see if belly size could help docto…

This study tested whether the ACCUVEIN, a device that projects veins onto the skin, can detect changes in vein size caused by the nervous system. Researchers had 12 healthy adults lie on a tilt table and slowly move from lying flat to standing upright. They used the device to see…

This early-phase study looked at whether xenon gas, used as anesthesia, changes the nerve signals that control muscles and blood pressure. Eight healthy volunteers received xenon gas for 30 minutes while researchers measured nerve activity, heart rate, and blood chemicals. The go…
