    Notes: Abstract. IgG immune complexes are of central importance in the humoral immune system and strongly implicated in the pathogenesis of hematologic and rheumatic autoimmune disorders. Cross-linking of receptors for the Fc domain of IgG antibodies (FcγRs) triggers a wide variety of effector functions including phagocytosis, antibody-dependent cellular cytotoxicity, and release of inflammatory mediators, as well as immune complex clearance and regulation of antibody production. In this way, FcγR provide an essential feedback between the humoral and cellular immune response. In the past, significant advances have been made in the molecular dissection of FcγR function using cellular transfection systems. Current approaches designed to target and change individual FcγR genes in mice have given further insight into their specific contributions to systemic processes, also indicating them to be important immunoregulatory receptors involved in various disease states of allergy, autoimmunity, and inflammation. Future work on targeting FcγR binding sites in combination with humanized FcγR mouse models will lead to novel therapeutic strategies in the treatment of IgG-mediated human disease in which FcγR activation plays an integral part.

    Notes: Summary 1. Recordings were made from 16 ascending tract cells in the spinal cords of anaesthetized, spinalized cats before and after an acute arthritis was produced by injection of kaolin and carrageenan into the knee joint. 2. The responses tested routinely were to passive flexion of the knee, an innocuous movement. In some cases, responses to other movements were also tested, and changes in background discharge rates were monitored. 3. Control recordings for a period of 1 h or in 3 cases of 3 h indicated that the responses to flexion were reasonably stationary. 4. Four tract cells that initially showed little or no response to flexion of the knee joint developed large responses within 1 to 2 h after inflammation of the joint. 5. Another 9 cells were tested that had responses to flexion of the knee joint prior to inflammation. In 6 cases, inflammation produced enhanced static or transient responses. In 2 cases, the effect of flexion was initially inhibitory or variable, but after inflammation these cells showed large excitatory responses. In the other case, inflammation had no effect. Background discharges were increased by inflammation in 6 of these 9 cells. 6. The effect of inflammation of the knee joint was tested on 3 tract cells that had no clearly defined receptive field in the knee. In 1 case, a response developed to knee flexion after acute inflammation was produced. In the other 2 cases, there were initially responses to knee flexion, but these were unchanged by inflammation. 7. Two of the cells tested had bilateral receptive fields in or around the knee joints. Inflammation of one knee joint enhanced the responses to flexion of the same but not of the contralateral knee in one case but greatly increased the responses to flexion of both knees in the other case. 8. Injections of prostaglandin (PGE2) caused an enhancement of the responses to knee flexion beyond that caused by inflammation in 5 of 7 cases. One cell whose responses to flexion of the knee were unaffected by inflammation showed inhibitory responses to prostaglandin injections into the inflamed knee joint. 9. The effects of inflammation on the responses of ascending tract cells of the spinal cord appear to serve as a useful neural model of the events responsible for the development of arthritic pain.

    Notes: The capability of optical measurements to elucidate adsorption as well as absorption phenomena is demonstrated by using oxygen interaction with copper films as an example. The films (thickness about 30 nm) deposited under UHV conditions on glass substrates show a polycrystalline structure with a marked (111) fibre texture. Gas doses were provided at 460 K while recording simultaneously the ellipsometric response (λ = 1152 nm) and the electrical resistivity. The optical properties of the clean films correspond to well-known bulk data. O2 adsorption causes the ellipsometric angles σΔ and σψ to change by 0.05° and 0.02°, respectively. At pressures of about 1 Pa oxygen begins to penetrate into the interior of the sample which manifests itself in a further drastic increase of σΔ = 30° and σψ = 5°.

    Description / Table of Contents: Transition Metal Peroxofluoro Complexes. VIII. Crystal Structure of K2Ti(O2)F4. · 1/2H2O. Structural Comparison and Spectroscopic Data of the Compounds K2Ti(O)2F4 · xH2O (x = 1, 1/2, 0)The yellow hemihydrat K2Ti(O2)F4 · 1/2 H2O crystallizes monoclinic (space group C2/c, a = 1680.5(6), b = 653.2(1), c = 1224.3(4) pm, β = 115.8(1)°, Z = 8, Rw = 0.038 for 1113 independent reflections). It contains isolated, dinuclear, di(μ-fluoro)-bridged [Ti2(O2)2F8]4- anions, as known by orange coloured K2Ti(O2)F4 · H2O [1]. They are arranged in layers which are parallel to the (100) plane, whereas they are linked by hydrogen bonds forming infinite chains in K2Ti(O2)F4 · 1/2 H2O. Anhydrous K2Ti(O2)F4 - even yellow - crystallizes monoclinic with a = 828.9(2), b = 1107.6(2), c = 1303.9(3) pm, β = 92.29(2)°. I.r. and Raman spectra of all compounds are listed and interpreted. On the basis of the UV spectra the different colours of some titaniumperoxofluoro compounds are discussed in relation to the titanium-peroxid bonding.
    Notes: Das gelbe Hemihydrat K2Ti(O2)F4 · 1/2H2O kristallisiert monoklin (Raumgruppe C2/c, a = 1680,5(6), b = 653,2(1), c = 1224,3(4) pm, β = 115,8(1)°, Z = 8, Rw = 0,038 für 1113 unabhängige Reflexe). Es enthält isolierte, zweikernige, di(μ-fluoro)-verbrückte [Ti2(O2)2F8]4--Anionen, wie sie vom orangefarbenen K2Ti(O2)F4 · H2O her schon bekannt sind [1]. Während sie dort jedoch über Wasserstoffbrücken zu Ketten verknüpft sind, sind sie im K2Ti(O2)F4 · 1/2 H2O in Schichten parallel zur (100) Ebene angeordnet. Das ebenfalls gelbe wasserfreie K2Ti(O2)F4 kristallisiert monoklin mit den Gitterkonstanten a = 828,9(2), b = 1107,6(2), c = 1303,9(3) pm, β = 92,29(2)°.IR- und Raman-Spektren aller drei Verbindungen K2Ti(O2)F4 · xH2O (x = 0, 1/2, 1) werden aufgeführt und interpretiert. Auf der Grundlage der UV-Spektren werden die unterschiedlichen Farben verschiedener Titanperoxofluoroverbindungen im Zusammenhang mit ihren Bindungsverhältnissen diskutiert.

    Description / Table of Contents: Acyl- and Alkylidenephosphines. XXX. Molecular and Crystal Structure of 1H-1,3-Benzazaphosphole1H-1,3-Benzazaphosphole synthesized by Issleib and coworkers [2], crystallizes in the orthorhombic space group Pna21 with following dimensions of the unit cell Determined at a temperature of measurement of -80 ± 3°C: a = 828.6(2); b = 557.1(1); c = 1433.5(4) pm; Z = 4. An X-ray Structure Determination (Rg = 0.061) shows the molecule to be characterized by a rather narrow C—P=C angle of 88.2(4)° as well as a shortened single {180.7(7)} and a typical double bond {169.5(9) pm} between the carbon atoms and the twofold coordinate phosphorus. All the other bond lengths differ only scarcely from corresponding values of the homologues benzimidazole 2a [3, 4] and 1H-1,3-benzazarsole 2c [5]. In spite of the fact that all three solids crystallize in the same space group, only the heterocycles 2b and 2c are isotypic; intermolecular hydrogen bonds as found in 2a, are no longer present in the heavier homologues.
    Notes: Das Von Issleib u. Mitarb. [2] dargestellte 1H-1,3-Benzazaphosphol 2b kristallisiert orthorhombisch in der Raumgruppe Pna21 mit folgenden, bei einer Meßtemperatur Von -80 ± 3°C bestimmten Abmessungen der Elementarzelle: a = 828,6(2); b = 557,1(1); c = 1433,5(4) pm; Z = 4. Nach den Ergebnissen einer Röntgenstrukturanalyse (Rg = 0,061) weist das Molekül bei einem C—P=C-Winkel Von nur 88,2(4)° eine auf 180,7(7) pm Verkürzte Einfach- und eine mit 169,5(9) pm typische Doppelbindung zwischen Den Kohlenstoffatomen und Dem zweifach koordinierten Phosphoratom auf. Die übrigen Bindungslängen weichen kaum Von Den für die Homologen Benzimidazol 2a [3, 4] und 1H-1,3-Benzazarsol 2c [5] publizierten Werten ab. Obwohl bei allen drei Kristallstrukturen die gleiche Raumgruppe auftritt, sind nur die Heterocyclen 2b und 2c zueinander isotyp; die für Verbindung 2a charakteristischen intermolekularen Wasserstoffbrücken bilden sich bei Den schwereren Homologen nicht mehr aus.
