Article Synopsis
- * This study introduces a new photoswitch, sterically hindered stiff stilbene (HSS), which shows significant structural changes and stability, allowing for enhanced understanding and control of polymer conformations.
- * The research demonstrates the ability to reverseibly control hydrodynamic volume in solution and achieve significant macroscopic changes in properties like transmittance and wettability, highlighting the potential for advanced applications in smart materials.

Article Synopsis
- * A case involving a 71-year-old woman with lymphoma resulted in fatal anaphylactic shock following her first dose of rasburicase, leading to multiple complications including heart compression and significant bleeding.
- * This case highlights that while it’s uncommon, rasburicase can cause deadly anaphylaxis even in patients who have not previously been exposed to the drug.
Objective: The angiography systems A (A) and B (B), both incorporated at our hospital, are equipped with metal artifact reduction (MAR) applications. In clinical practice, it is crucial to understand the characteristics of MAR in both systems given that endovascular treatments are occasionally administered with both. In this study, we compared the artifact reduction effects of MAR on equipment A and B and clarified the differences between the two systems.

However, limited genetic information is available on the bear roundworm in Japanese populations. This study evaluated the genetic composition of bear roundworms isolated from wild Japanese black bears indigenous to Lake Towada, Japan.

Furthermore, this report is the first to achieve the single-crystal X-ray structural analyses of phenazine-2,3-diol PD1 and its monoalkoxy derivative PD2, since the report on the synthesis of PD1 70 years ago. Indeed, it was found that PD1 and PD2 molecules exist in the keto form (PD1-K) and the enol form (PD2-E), respectively, in the crystal, and the neighboring PD1-K and PD2-E molecules are linked by one-dimensional intermolecular NH⋯O and OH⋯N hydrogen bonding, respectively.
