Objective: Conventional decompression surgery for beak-type ossification of the posterior longitudinal ligament (OPLL) of the thoracic spine, whether approached anteriorly or posteriorly, poses several challenges, including technical complexity, cerebrospinal fluid leakage, incomplete decompression, and potential neurological deterioration. Therefore, the authors introduce a novel technique, anterior sliding decompression osteotomy (ASDO), for thoracic myelopathy caused by OPLL and evaluate the efficacy and safety of this technique.
Methods: Six patients (4 men and 2 women) who underwent ASDO surgery for beak-type OPLL in the thoracic spine with a follow-up period of at least 2 years were included in the cohort.
With the development of the Korean economy, demand for high-quality beef, specifically Hanwoo beef, is escalating, with marbling traits-measured by the widely used marbling score-being a key contributor to meat palatability. The differences between the high-quality and the lower-quality meat, according to the satisfaction of the customers, are not the result from only the degree of marbling but also from the delicacy of the marbling flecks distribution. Using the computer marbling analysis technique, an index for quantifying marbling fineness of 256 sirloin cuts at 12th- 13th thoracic vertebra named F7 index was developed in this study.

This study aimed to explore the changes in foot alignment following CLO in patients with CP, utilizing both radiographic evaluations and dynamic foot-pressure assessments.
Methods: A retrospective study of 282 feet in 180 ambulatory patients was performed.
Banded iron formations (BIFs), significant iron ore deposits formed approximately 2.3 billion years ago under low-oxygen conditions, have recently gained attention as potential geological sources for evaluating hydrogen (H₂) production. BIFs are characterized by high concentrations of iron oxide (20 to 40 wt.
