Early Recurrence of Thoracic Ossification of the Ligamentum Flavum After Posterior Decompression Surgery: A Case Report.

Thoracic ossification of the ligamentum flavum (OLF) is known to result in spinal canal stenosis and myelopathy. It is typically treated through decompressive laminectomy and resection of the ossified ligament, which is known to improve neurological deficits. However, the recurrence of OLF post-surgery remains a relatively undocumented and complex issue.

Destabilization of Sn 5s Lone-Pair States of SnO through Dimensional Crossover.

Materials exhibiting unique electronic properties arising from a characteristic crystal structure have physical properties that are sensitive to structural dimensionality. This study involves the destabilization of Sn 5s lone-pair states of SnO films by decreasing their structural dimensionality in the out-of-plane direction. The inherent dispersive band structure of the SnO films remained unchanged between 80 and 11 nm.

Actinomycosis of the Middle Ear in Children: Case Report and Literature Review.

Actinomycosis of the middle ear is a rare infectious disease, characterized by a slowly progressive clinical course. We report the case of a 9-year-old girl with recurrent otitis media, who presented with clinical signs of a cholesteatoma. She underwent tympanoplasty and ossiculoplasty.

Synthesis of rhombohedral LaCuO thin films using the oxidation effect of NaClO solution.

LaCuO is one of the most fundamental cuprate perovskite blocks and has a similar structure to the cuprate high-temperature superconductor. Therefore, some consider that a study on LaCuO is one of the clues to clarify the mechanism of cuprate high-temperature superconductivity. However, since the synthesis of bulk LaCuO is difficult due to the need for the high-pressure and high-temperature (HPHT) method, not enough research on LaCuO has been done so far.
