The biochemical and genetic search for a bc(1) complex in Rhodothermus marinus was always fruitless; however, a functional equivalent, i.e. having quinol:cytochrome c oxidoreductase activity was characterized. Now, with the sequencing of R. marinus genome, it was possible to assign the N-terminal sequences of several proteins of this complex to its coding genes. The alternative complex III from...

Left invariant complex structures on U (2) and SU (2) × SU (2) revisited. Abstract We compute the torsion-free linear maps J : su(2) → su(2), deduce a new determination of the integrable complex structures and their equivalence classes under the action of the automorphism group for u(2) and su(2) ⊕ su(2), and prove that in both cases the set of complex structures is a differentiable manifold. u...

INTRODUCTION Demineralised bone matrix (DBM) is an allograft material widely used as a bone filler and bone graft substitute. DBM contains bone morphogenetic proteins (BMPs), which induce and regulate bone formation during embryogenesis and in postnatal life. AIMS AND OBJECTIVES To investigate the osteoinductivity of DBM augmented with xenogeneic BMP-complex at different doses. MATERIALS AN...
