    and S-200 gel-filtration chromatography yielded a 50 kDa BGlu1 with >95% purity. The free enzyme and a complex with 2,4-dinitrophenyl-2-deoxy-2-fluoro-β-D-glucopyranoside inhibitor were crystallized by microbatch and hanging-drop vapour diffusion. Small...H 6.7 to yield larger crystals. Crystals with and without inhibitor diffracted to 2.15 and 2.75 Å resolution, respectively, and had isomorphous orthorhombic unit cells belonging to space group P2 12121. © 2006 International Union of Crystallography All

    Role of tissue porosity in thermal damage during microwave ablation
    (2026-03-01) Wessapan T.; Keangin P.; Rattanadecho P.; Somsuk N.; Wessapan T.; Mahidol University
    simulations grounded in Maxwell's equations and porous media theory. Tissue necrosis was forecasted via an Arrhenius model, dependent on temperature and exposure time. The study findings show that higher tissue porosity leads to a more diffused and elongated
