AbstractSiderophores play a very important role in the uptake process of iron by bacteria. Due to the so-called active transport the uptake of siderophores by bacteria is very specific, which makes the use of siderophores as effective shuttles for antibiotics in the treatment of infections and other diseases caused by bacteria highly attractive. In order to further investigate the transport and incorporation of siderophores into the bacteria cells, distinct molecular probes are needed. Especially artificial siderophores, that show a specific intrinsic fluorescence, are highly attractive for such monitoring purposes. A promising candidate of such a fluorescent artificial siderophore is bis-2,3-dihydroxybenzoyl-2,6-dimethylamino-pyridine (pyridinochelin, PY). The fluorescence properties of PY were investigated in different solvents and in the presence of different metal ions. It was found that PY in its free form shows a complex fluorescence behavior. In methanol a clear dual fluorescence is observed. In aqueous solution intermolecular interactions with water molecules are determining the intrinsic fluorescence. Upon complexation with metal ions (Me3+ = Eu3+, Tb3+, Al3+, Fe3+) the fluorescence characteristics changed. The fluorescence quantum yield of PY decreased upon addition of Me3+ - except for Al3+, which showed no fluorescence quenching. The fluorescence decay of PY loaded with metal ions showed a nicely mono-exponential fluorescence decay, which was in contrast to PY in the absence of metal ions. This drastic change in the fluorescence properties of PY upon metal ion complexation makes PY highly attractive as a fluorescence probe for the investigation of siderophore action and siderophore-mediated transport processes

Two thiostannates [Co(dien)2](H2dien)Sn2S6 (1) (dien = diethylenetriamine) and [Zn(tren)]2Sn2S6 (2) (tren = tris(2-aminoethyl)amine) were prepared under solvothermal conditions and structurally characterized. Both 1 and 2 contain dinuclear [Sn2S6]4− anions built from two SnS4 tetrahedra sharing a common edge. 1 consists of discrete [Sn2S6]4− anions with rare u-fac-[Co(dien)2]2+ and H2dien2+ as counterions, while 2 consists of neutral centrosymmetric [Zn(tren)]2Sn2S6, in which the [Sn2S6]4− anion connects two coordinatively unsaturated complex [Zn(tren)]2+ cations as a bidentate ligand via trans terminal S atoms. The different cations act as structure-directing agents that have a significant influence on the arrangement of the [Sn2S6]4− anions in their crystal structures. 2 exhibits fluorescence properties at room temperature.

Objective: This study examines retrospective correlates of nonshared family environment prior to onset of disease, by means of multiple familial informants, among anorexia and bulimia nervosa patients. Methods: A total of 332 participants was included (anorexia nervosa, restrictive type (AN-R): n = 41 plus families); bulimic patients (anorexia nervosa, binge-purging type; bulimia nervosa: n = 59 plus families). The EATAET Lifetime Diagnostic Interview was used to establish the diagnosis; the Subjective Family Image Test was used to derive emotional connectedness (EC) and individual autonomy (IA). Results: Bulimic and AN-R patients perceived significantly lower EC prior to onset of disease compared to their healthy sisters. Bulimic patients perceived significantly lower EC prior to onset of disease compared to AN-R patients and compared to their mothers and fathers. A low family sum – sister pairs sum comparison – of EC had a significant influence on the risk of developing bulimia nervosa. Contrary to expectations, AN-R patients did not perceive significantly lower levels of IA compared to their sisters, prior to onset of disease. Findings of low IA in currently ill AN-R patients may represent a disease consequence, not a risk factor. Conclusions: Developmental child psychiatrists should direct their attention to disturbances of EC, which may be present prior to the onset of the disease.
