[Quantification of Clitidine in Paralepistopsis acromelalga Using Quantitative NMR Method].

Because one toxic component of Paralepistopsis acromelalga, clitidine, is not commercially available as a reagent and because standards are difficult to obtain, a quantitative NMR method that requires no standard was investigated for this study. To compare the quantitative values obtained using the two methods, the absolute purity of the standard used for the LC-MS/MS method was calculated using quantitative NMR. The result was calculated as 89.

Analysis and Visualization of Multiple Hi-C and Micro-C Data with CustardPy.

Three-dimensional (3D) genome structure plays crucial roles in biological processes and disease pathogenesis. Hi-C and Micro-C, well-established methods for 3D genome analysis, can identify a variety of 3D genome structures. However, selecting appropriate pipelines and tools for the analysis and setting up the required computing environment can sometimes pose challenges.

A case of BRCA1-mutated giant pancreatic acinar cell carcinoma successfully treated with modified FOLFIRINOX therapy and radical resection.

Pancreatic acinar cell carcinoma (PACC) is a rare type of pancreatic cancer; further, its pathogenesis and treatment strategies remain unclear. We report the case of a 70-year-old man who presented with a chief complaint of abdominal distention. Computed tomography scans revealed a large lobulated mass (tumor diameter: 150 mm) in the pancreatic body tail, which was diagnosed as a PACC through endoscopic ultrasonography fine needle aspiration.

Thoracoscopic enucleation of an esophageal glomus tumor in the prone position: a case report and literature review.

Background: Glomus tumors (GT) generally occur in the skin. However, esophageal GT, an extremely rare condition, has no established standardized treatment guidelines. Herein, we report the case of an esophageal GT successfully removed by thoracoscopic enucleation in the prone position using intra-esophageal balloon compression.

Dynamic Transformation of High-Architectural Nanocrystal Superlattices upon Solvent Molecule Exposure.

The cluster-based body-centered-cubic superlattice (cBCC SL) represents one of the most complicated structures among reported nanocrystal assemblies, comprised of 72 truncated tetrahedral quantum dots per unit cell. Our previous report revealed that truncated tetrahedral quantum dots within cBCC SLs possessed highly controlled translational and orientational order owing to an unusual energetic landscape based on the balancing of entropic and enthalpic contributions during the assembly process. However, the cBCC SL's structural transformability and mechanical properties, uniquely originating from such complicated nanostructures, have yet to be investigated.
