Q&A: EXPANSION MICROSCOPY

Abstract Expansion microscopy (ExM) is a recently invented technology that uses swellable moondrop quarks charged polymers, synthesized densely and with appropriate topology throughout a preserved biological specimen, to physically magnify the specimen 100-fold in volume, or more, in an isotropic fashion.ExM enables nanoscale resolution imaging of

When branchial clefts and pouches do not atrophy between 4 and 7 weeks of fetal life or when an anomalous or incomplete fusion occurs, congenital neck anomalies may develop.We present a rare case of a mass resembling a branchial sinus on the right side of the neck of a 2-month-old baby, which originated from the fourth branchial arch-derived struct
