Juvenile and mature neotenous Ambystoma mexicanum received allogeneic and xenogeneic skin transplants. Rejection times for 1st-set, and 3rd-set grafts were noted at 21 degrees C, and for axolotls placed in a cold-room at 7 degrees C 7 h post-grafting, 1 week post-grafting and 2 weeks post-grafting respectively. In all cases graft-rejection was chronic; 2nd(More)
Quantum mechanical and molecular dynamics methods were used to analyze the structure and stability of neutral and zwitterionic configurations of the extracted active site sequence from a Burkholderia cepacia lipase, histidyl-seryl-glutamin (His86-Ser87-Gln88) and its mutated form, histidyl-cysteyl-glutamin (His86-Cys87-Gln88) in vacuum and different(More)
Both juvenile (14-16 week) and adult (18 month) Ambystoma mexicanum reject skin allografts from adult Ambystoma more speedily than they reject such grafts from juvenile axolotls. Donor-specific histocompatibility antigen, prepared from splenocytes, is more effective in inhibiting adult host splenocyte migration when the antigen is prepared from spleen cells(More)
DFT/B3LYP calculations were employed to study the effects of tautomerism and explicit/implicit water molecules on Nuclear Quadrupole Resonance (NQR) and Nuclear Magnetic Resonance (NMR) tensors of nitrogen nuclei in tetrazole-5-thione structure. The obtained results revealed that nuclear quadrupole coupling constant (χ) and isotropic chemical shielding(More)
