    Beschreibung / Inhaltsverzeichnis: Sommario L'associazione di lesioni cerebrovascolari ischemiche e livedo reticularis è conosciuta come sindrome di Sneddon. La sua eziopatogenesi non è ancora stata chiarita. Noi descriviamo un caso in cui sono stati documentati un aumento dell'attività del fattore VII della coagulazione ed una carenza della forma libera della proteina S.
    Notizen: Abstract The association of ischemic cerebrovascular lesions with livedo reticularis is known as Sneddon syndrome. It affects young subjects, primarily women, and its neurological manifestations are TIAs, ischemic stroke, progressive dementia and epileptic seizures. Its etiopathogenesis has still to be clarified. Some authors have associated it with an antiphospholipid antibody syndrome. Recently it has been assumed that a defect in blood coagulation may be involved in its pathogenesis. Here we report a case in which both an increase in coagulation factor VII activity and a deficiency in free protein S were documented.

    Notizen: Singlet-triplet spin-orbit matrix elements, which govern the lowest 3B1u ← 1Ag transition in typical aromatic molecules like naphtalene and anthracene, are calculated with INDO molecular orbitals and the conventional spin-orbit one-electron hamiltonian. The correct order of magnitude of the triplet radiative lifetimes is obtained for the two molecules, when INDO MO coefficients are referred to a symmetrically orthogonalized basis. The possibility of using the semiempirical Hamiltonian is explored using ab initio wave-functions for a few test cases. Reasonably accurate doublet-doublet and singlet-triplet matrix elements have been computed.
