Mayo Clinic researchers have established the world’s first biobank of human salivary gland tissue-organoids to study chronic dry mouth, or xerostomia, an agonizing side effect of damaged salivary glands that affects millions.
Clinicians typically classify meningiomas—the most common type of brain tumor—into three grades, ranging from slow-growing to aggressive. But a new multi-institutional study suggests that appearances may be deceiving. If a tumor shows activity in a gene called telomerase reverse transcriptase, it tends to recur more quickly, even if it looks low-grade under the microscope.
