Spinal Ependymoma Identified Following Spinal Anesthesia for Cesarean Delivery.

Neuraxial anesthesia is preferred over general anesthesia for cesarean delivery when appropriate because the latter is associated with a higher incidence of airway complications and an increased need for neonatal resuscitation. Common complications of neuraxial anesthesia include backache and headache, whereas feared but rare complications include paraplegia, intraspinal hemorrhage, cauda equina syndrome, nerve injury, and epidural hematoma. This case report presents a 40-year-old female with undiagnosed and asymptomatic ependymoma who presented with concerning neurological symptoms after receiving spinal anesthesia for elective cesarean delivery.

Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D.
