A kidney and lung biopsy were performed on a patient with active Behçet's disease with renal and pulmonary involvement. Histologic, immunohistochemical and electron microscopic studies of the kidney biopsy specimen revealed a focal segmental necrotizing glomerulonephritis characterized by the presence of numerous subendothelial and occasional(More)
The search for isoform-specific enzyme inhibitors has been the focus of much recent research effort. Towards this goal, human recombinant cyclooxygenase-2 (EC 1.14.99.1, prostaglandin H synthase) was expressed in insect cells and purified to > 98% purity. Recombinant enzyme was characterized both by physical methods and activity measurements and shown to be(More)
The evolution of stress in a Ni–Hf diffusion couple during solid-state amorphization reaction has been monitored by substrate curvature measurements and x-ray diffraction. The latter technique allowed an independent determination of the contribution of changes in stress-free lattice parameter to the stress in the crystalline layers. The results indicate(More)
