Schwannomas arising from the 9th, 10th and 11th cranial nerves (also called jugular foramen schwannoma) without associated neurofibromatosis are relatively uncommon [1]. Schwannomas arising from the glossopharyngeal nerve are rare and fewer than 50 cases have been reported in the literature [1-4]. Glossopharyngeal schwannoma presenting in childhood is extremely rare and to our knowledge only 4 ...

We investigate the problem of determining shape a rotating celestial object - e.g., comet or an asteroid under its own gravitational field. More specifically, we consider symmetric with respect to one axis such as dumbbell that rotates around second perpendicular symmetry axis. assume can be modeled incompressible fluid constant mass density, which is regarded first approximation aggregate part...

During each active oscillation cycle, the vesicle shape undergoes a symmetry-breaking transformation from an up-down symmetric to asymmetric dumbbell followed by reverse symmetry-restoring transformation.

CCTG tetranucleotide repeat expansion is associated with a hereditary neurological disease called myotonic dystrophy type 2 (DM2). The underlying reasons that lead to genetic instability and thus repeat expansion during DNA replication remains elusive. Here, we have shown CCTG repeats have a high propensity to form metastable hairpin and dumbbell structures using high-resolution nuclear magneti...

The surgical strategies and methods used to treat dumbbell-shaped tumors located in the lumbar-foraminal region are controversial. Although a total facetectomy and combined intra- and extraspinal canal approach provide a wide operative field, facet fusion is required, which can be rather invasive. Here, we report a successful removal of a lumbar dumbbell-shaped schwannoma using a combined lamin...
