Robot-Assisted Boari-flap after Orthotopic Neobladder Using the KangDuo Surgical Robot-01 System.

Purpose: Benign ureteroenteric anastomosis stricture (BUES) is a well-recognized long-term complication following urinary diversion (1). While endourological interventions are often first-line, their success rates are limited (2, 3). Open uretero-ileal reimplantation remains the gold standard but is technically challenging and carries high complication risks (2).

Regulation of phenol oxidation into polymeric derivatives ready for flocculation using polyaluminum chloride.

Phenol, a toxic compound commonly found in wastewater, can be removed using the iron-tetraamidomacrocyclic ligand (Fe-TAML) and HO. However, it incurs high costs for Fe-TAML and HO, while treated water retains high chemical oxygen demand (COD) and CO emissions. To address these challenges, this study proposes converting phenol into polymeric derivatives followed by flocculation.

Large Tunneling Magnetoresistance in Nonvolatile 2D Hybrid Spin Filters.

Ferromagnetic semiconductors offer an efficient way to achieve high spin polarization via spin filtering effect. Large tunneling magnetoresistance (TMR) can then be realized when multiple spin filters are put in series, as recently demonstrated in van der Waals 2D A-type antiferromagnets such as CrI_{3} and CrSBr. However, the interlayer antiferromagnetic ground state of these magnets inherently results in a high resistance state at zero field, and this volatile behavior limits potential applications.

Expression of a Recombinant Cholesterol Esterase from in and Its Applicability for γ-Oryzanol Hydrolysis.

Ferulic acid (FA) exhibits antioxidant and anti-inflammatory properties, making it valuable for numerous industrial applications. Traditionally, FA is produced by the alkaline hydrolysis of -oryzanol, which is typically associated with wastewater generation. Recently, an increasing demand of natural FA necessitates its green production via enzymatic hydrolysis of -oryzanol, a mixture comprising triterpene alcohol ferulates and phytosteryl ferulates.
