    Notes: Summary In haematogenic Candida infection of the CNS pseudohyphae are first found in capillaries from which they grow into the surrounding tissue. From here they involve the outer parts of the vessel walls. The lamina elastica interna first embarrasses their growth, but finally they penetrate into the tunica intima and cause a lesion that leads to thrombosis. The possibility of fungi spread via the vessels this way is mentioned. The affinity of Candida albicans for the vessel walls is discussed.

    Cataract in a fetus at risk for oculo-cerebro-renal syndrome (lowe) (1977)

    Description / Table of Contents: Summary A high-risk pregnancy for X-linked recessive inherited Lowe's syndrome was terminated due to a male karyotype in the cultured amniotic fluid cells. The eyes of the male fetus showed specific cataracteous changes of the lens. A posterior lenticonus was due to a defect of the lens capsule. The lenses were of normal size. Loss of lens material through a lens capsule defect could account for the small discoid lens usually seen in Lowe's syndrome. Amino acids in amniotic fluid had normal concentrations except lysine and proline which were markedly elevated.
    Notes: Zusammenfassung Bei einer Schwangeren, die bereits einen Jungen mit Lowe-Syndrom hat, wurde eine Amniocentese durchgeführt. Die Schwangerschaft wurde unterbrochen, nachdem sich in den kultivierten Zellen der Amnionflüssigkeit ein männlicher Karyotyp zeigte und damit eine Wahrscheinlichkeit von 50% für die Geburt eines weiteren Kindes mit dieser X-chromosomal rezessiv erblichen Erkrankung bestand. Der männliche Fet bot die für das Lowe-Syndrom charakteristischen Linsentrübungen. Es bestand ein Lenticonus posterior mit Defekt der hinteren Linsenkapsel; die bisher bekannte kleine, discoide Linse des Lowe-Syndroms entsteht somit möglicherweise durch Verlust von Linsenmaterial bei defekter hinterer Linsenkapsel. Die Aminosäurenkonzentrationen im Fruchtwasser waren mit Ausnahme von deutlichen Erhöhungen von Lysin und Prolin normal.

    Der intrarenale Nitrofurantoin-Transport am Menschen (1966)

    Description / Table of Contents: Summary The intrarenal handling of Nitrofurantoin (Furadantin®) was studied with standard clearance methods in 42 patients with normal and reduced renal function. In normal human kidneys the Nf amount excreted in the urine consists of 16,7% filtrated in the glomerulus und 83,3% secreted by the proximal tubule. The plasma binding of Nf was 60% (ultracentrifugation). The secretion in the proximal tubule is reduced by Sulfinpyrazon (Anturan®) and competitively inhibited by para-amino-hippuric acid (PAH). The transportmechanism for Nf is less effective than for PAH. Under conditions of acid urine about 30% of the total amount of Nf followed non-ionic backdiffusion. This amount may theoretically be sufficient for a chemotherapeutic effect in renal interstitial tissue and depends on the tubular capacity for Nf-secretion.
    Notes: Zusammenfassung An 42 Patienten mit und ohne Nephropathien wurde mit Clearancemethoden gezeigt, daß Nitrofurantoin (Furadantin®) in gesunden menschlichen Nieren zu 16,7% glomerulär filtriert und zu 83,3% tubulär sezerniert wird. Die Bindung an die Plasmaeiweiße betrug 60% (Ultrazentrifugenmethode). Die Sekretion vollzieht sich in den proximalen Tubulusabschnitten und ist sowohl durch Sulfinpyrazon (Anturan®) reduzierbar als auch durch Para-Aminohippursäure kompetitiv hemmbar. Nitrofurantoin hat offensichtlich eine geringere Affinität als PAH zu dem gemeinsamen Transportmechanismus. Da die schwache Säure Nitrofurantoin der „non-ionic diffusion“ unterliegt, besteht bei ausreichender proximaler Nf-Sekretion und bei saurem Harn eine Rückdiffusion beträchtlicher Nf-Mengen in den distalen Nephronabschnitten.

    Rotational energy transfers in ionized molecular gases: the NH 4 + system (1993)

    Notes: Summary The interaction between H+ ions and the ground electronic state of NH3 molecules is computed from first principles, using an expansion over analytic functions (GTO orbitals) to construct a potential energy surface (PES) at the SCF-HF level of approximation. By employing a rigid-rotor (RR) description of the symmetric-top target molecule, the interaction is expanded in symmetry-adapted coefficients and the latter are fitted with analytic polynomials. The full quantum treatment of rotationally inelastic collisions at the energies of existing molecular beam experiments produces reasonable accord with these data and suggests physical reasons for the observed low efficiency of the inelastic processes.

    Description / Table of Contents: Riassunto Si riportano estesi calcoliab initio per gli stati elettronici legati della molecola del BF3 nel suo stato fondamentale e si descrive un modello semplice che permette di ottenere gli stati ionici relativi ad una vacanza nel guscioK dell’atomo di boro. Si esaminano il processo di riarrangiamento della distribuzione di carica molecolare che ha luogo dopo la ionizzazione iniziale ed i suoi effetti sullo spettro di assorbimento X relativo all’atomo centrale. Si evidenzia ed analizza il valore puramente qualitativo di ogni assegnazione delle righe di assorbimento che sia basata unicamente sulla struttura dello stato iniziale non perturbato.
    Notes: Summary Extensive, bound-state calculations for the electronic ground state of the BF3 molecule are reported and a simple model is employed to generate its ionic state associated with aK-shell vacancy in the boron atom. The rearrangement of the molecular-charge distribution that follows the initial ionization process is examined within the present model and its effect on the full boron X-ray absorption spectra is discussed. The inadequancy of band classifications which are based only on initialstate calculations in providing anything more than qualitative results is again observed and analysed.
