Under physiological conditions, the trans-presentation of interleukin-15 (IL-15) by the IL-15 receptor α on the cell surface allows to confine and tune the IL-15-mediated immune responses. Therefore, targeting strategies that mimic this situation at the tumor sites appear especially promising for anticancer immunotherapy.

A hybrid method of subgrid FDTD(2,2) with FDTD(2,4) is presented. Both the standard FDTD(2,2) as well as the hybrid technique are applied to shielding effectiveness analysis of a scaled model of a Boeing 757. Also, analysis of EMI generated by personal electronic devices is performed on the same scaled fuselage model.

In the title compound, C17H16O3, the benzene rings are twisted by 63.54 (5)°. The twist is similar to that found in the unsubstituted compound, phenyl benzoate. The crystal packing features C-H⋯O hydrogen bonds.

Initial attempts to make [Ni(H2O)2(15-crown-5)](NO3)2, i.e. to insert the Ni2+ ion into the 15-crown-5 macrocycle, gave the mono- (two polymorphs) and dihydrate of a co-crystal of[Ni(H2O)6](NO3)2 and 15-crown-5 (1,4,7,10,13-pentaoxacyclopentadecane=15C5). Synthetic routes designed to restrict the water available to the Ni2+ cation gave three additional compounds, [Ni(H2O)6](NO3)2-trans-[Ni(H2O)...

Two dinickel mimics, [LNi2(DMF)4](ClO4)3 () and [L'Ni2(CH3CN)4](ClO4)3 (), for the active site of urease supported by a disubstituted benzoate polydentate ligand were synthesized and fully characterized, subsequently addition of urea afforded two urea adducts, [LNi2(urea)4](ClO4)3 () and [L'Ni2(urea)4](ClO4)3 ().

The structure of the title compound (4CP4CBA), C(13)H(8)Cl(2)O(2), resembles those of 4-methyl-phenyl 4-chloro-benzoate (4MP4CBA), 4-chloro-phenyl 4-methyl-benzoate (4CP4MBA) and 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), with similar bond parameters. The dihedral angle between the two benzene rings in 4CP4CBA is 47.98 (7)°, compared with 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57...

MHC/self peptide interactions with cognate coreceptor/TCR complexes are central to homeostasis of the T cell repertoire. Recent reports have also underlined the critical role of IL-15/IL-2 cytokines in regulating this homeostatic process. In this study, we investigate mechanisms that regulate potentially autoreactive CD8 cells that have escaped intrathymic selection. These cells, upon exit from...

The efficiency of A* searching depends on the quality of the lower bound estimates of the solution cost. Pattern databases enumerate all possible subgoals required by any solution, subject to constraints on the subgoal size. Each subgoal in the database provides a tight lower bound on the cost of achieving it. For a given state in the search space, all possible subgoals are looked up in the pat...

The structure of the title compound (23DMPBA), C(15)H(14)O(2), resembles those of phenyl benzoate (PBA), 3-methyl-phenyl benzoate (3MePBA), 2,6-dichloro-phenyl benzoate (26DC-PBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 23DMPBA is 87.36 (6)°, compared with values of 55.7° in PBA, 79.61 (6)° in 3MePBA and 75.75 (10)° in ...

Proteases have a variety of strategies for selecting substrates in order to prevent uncontrolled protein degradation. A recent crystal structure determination of prolyl oligopeptidase has suggested a way for substrate selection involving an unclosed seven-bladed beta-propeller domain. We have engineered a disulfide bond between the first and seventh blades of the propeller, which resulted in th...
