Inelastic neutron scattering measurements on Ba8Ga16Ge30 and Sr8Ga16Ge30 indicate the presence of soft local modes with Einstein oscillator energies of 4.9 +/- 0.1 and 4.4 +/- 0.1 meV, modes which are associated with the lowest "rattling" mode of the Ba(B) and Sr(B) guests, respectively. Nuclear inelastic scattering measurements on Eu8Ga16Ge30 yield Einstein oscillator energies of between 3.0 +/- 0.3 and 7.5 +/- 1.2 meV for the different modes of the Eu guests. Further, the resonant character of the measurements on Eu8Ga16Ge30 reveals, without question, that neither of the Eu guests exhibit any vibrational modes above 9 meV. [less ▲]

Sintered, textured and single crystal products of the layered misfit [Bi0.81CaO2](2)[CoO2](1.69) cobaltite have been successfully synthesized and characterized. Based on structure and texture models, the orientation distribution of the hot-forged sample was successfully analysed by neutron diffraction. The results gave a clear description of the fiber texture with c-axes of the plate-like grains aligned parallel to the hot-forging direction. In terms of transport properties, the decrease of the electrical resistivity according to the degree of alignment and crystallinity of the materials evidenced the important role of the texturation and the strong anisotropy existing in these misfit layered cobaltites.

Lyme disease is a pathology caused by members of the Borrelia burgdorferi sensu lato (s.l.) complex, most often by B. burgdorferi sensu stricto (s.s.). They are transmitted mainly by Ixodes ricinus ticks. After a few hours of infestation, neutrophils massively infiltrate the bite site. They can kill Borrelia via phagocytosis, oxidative burst and hydrolytic enzymes. However, factors in tick saliva promote propagation of the bacteria in the host even in the presence of a large number of neutrophils. Neutrophil extracellular trap (NET) consists in the extrusion of the neutrophil’s own DNA, forming traps that can retain and kill bacteria. The production of reactive oxygen species (ROS) is apparently associated with the onset of NEtosis. Here we describe NETs formation at the tick bite site in vivo in mice. We show that Borrelia burgdorferi s.s. spirochetes become trapped and killed by NETs in humans and that the bacteria do not seem to release significant nucleases to evade this process. Saliva from I. ricinus did not affect NET formation by human neutrophiles or it stability. However, it strongly decreased neutrophil ROS production, suggesting that a strong decrease of hydrogen peroxide does not affect NET formation. Finally, round bodies were observed trapped in NETs, some of them staining as live cells. This observation could help contribute to a better explanation of erythema migrans. [less ▲]

Objective-To compare measurements of myeloperoxidase (MPO) in plasma, laminar tissues, and skin obtained from control horses and horses given black walnut heartwood extract (BWHE). Animals-22 healthy 5- to 15-year-old horses. Procedures-Horses were randomly assigned to 4 groups as follows: a control group given water (n = 5) and 3 experimental groups given BWHE (17) via nasogastric intubation Experimental groups consisted of 5, 6, and 6 horses that received BWHE and were euthanatized at 1.5, 3, and 12 hours after intubation, respectively. Control horses were euthanatized at 12 hours after intubation. Plasma samples were obtained hourly for all horses. Laminar tissue and skin from the middle region of the neck were harvested at the time of euthanasia. Plasma and tissue MPO concentrations were determined via an ELISA; tissue MPO activity was measured by use of specific immunologic extraction followed by enzymatic detection. Results-Tissues and plasma of horses receiving BWHE contained significantly higher concentrations of MPO beginning at hour 3. Laminar tissue and skin from horses in experimental groups contained significantly higher MPO activity than tissues from control horses. Concentrations and activities of MPO in skin and laminar tissues were similar over time. Conclusions and Clinical Relevance-in horses, BWHE administration causes increases in MPO concentration and activity in laminar tissue and skin and the time of increased MPO concentration correlates with emigration of WBCs from the vasculature. These findings support the hypothesis that activation of peripheral WBCs is an early step in the pathogenesis of acute laminitis. [less ▲]

Neutrophilic eccrine hidradenitis (NEH) is a rare neutrophilic dermatosis occurring most frequently during induction chemotherapy for a variety of malignancies. We report a case of NEH in a 41-year-old woman with acute myeloblastic leukemia under daunorubicin, cytarabine and etoposide chemotherapy. She developed red, tender and painful nodules on a shoulder. The lesions resolved spontaneously. Histological examination is mandatory as the clinical presentation of this dermatosis is highly polymorphic. Leukemia cutis, sepsis, deep fungal infection and Sweet's syndrome must be excluded as these implicate different therapies. [less ▲]

The observation of Jupiter's FUV aurora during the Cassini Jupiter flyby has almost doubled the number of available HST-STIS images of Jupiter's poles. This large 2-month-dataset has been statistically analyzed to provide a new "reference oval", actually a statistical average location of the auroral emission, both in the North and in the South. This study clearly shows that the auroral morphology is CML dependent, meaning that substantial local time effects take place during one Jovian rotation. Consequently, the new "reference oval" is described as a set of statistical average locations as a function of CML range. A more detailed analysis shows time variation of the morphology within timescales ranging from weeks to hours which might be attributed to changing conditions in the magnetosphere. This study provides a quantitative basis for future morphological analysis and correlation of the FUV aurora with auroral features observed with other instruments at different wavelengths, such as the Chandra x-ray observatory or the IRTF telescope. This statistical average is of prime importance for estimating the origin and nature of the impinging particles giving rise to the auroral emission. It also provides crucial constraints for the modeling of the Jovian magnetosphere, and the energy inputs to Jupiter's upper atmosphere. [less ▲]

The Dufour gland of the African ant Crematogaster nigriceps contains a mixture of at least eight 1-heptadec(en)yl- and 1-nonadec(en)yl-1,3,5-trihydroxycyclohexane derivatives, the mono-unsaturated components being the major ones (about 65%). They are accompanied by small amounts of (Z,Z)-dienic derivatives (<10%). The structures, the relative and absolute configurations, and the preferred conformation of these new compounds have been established by spectroscopic and chemical methods, whereas the positions of the double bond in the alkenyl chains were determined by DMDS derivatisation followed by linked scan EIMS.
