In the title compound, C9H13Cl2NO2, the piperidine ring shows a chair conformation and the O-C-C-O torsion angle between the carbonyl groups is 183.6 (4)°. In the crystal, mol-ecules are linked into an infinite layer along the ab plane by a bifurcated C-H⋯O hydrogen bond between the carbonyl O atom adjacent to the methyl group and one of the methyl-ene groups next to nitro-gen and an additional...

We present broadband V,I CCD photome-try for ∼ 1700 stars towards the Galactic globular cluster Palomar 12, covering a field of 10. ′ 7 × 10. ′ 7. From these data, a color-magnitude diagram from the red giant branch tip to ∼ 2 mag below the cluster's turn-off is obtained. From a comparison with the color magnitude diagrams of 47 Tuc and M5, and using different theoretical models, we confirm tha...

We study c-crossing-critical graphs, which are the minimal graphs that require at least c edge-crossings when drawn in plane. For every fixed pair of integers with ≥ 13 and d 1, we give first explicit constructions containing arbitrarily many vertices degree greater than d. also show such unbounded do not exist for ≤ 12, precisely, there exists a constant D graph 12 has maximum most D. Hence, b...

Infection by Listeria monocytogenes (Lm) causes serious sepsis and meningitis leading to mortality in neonates. This work explored the ability of CD11c(high) lineage DCs to induce CD8+ T-cell immune protection against Lm in mice before 7 days of life, a period symbolized by the absence of murine IL-12p70-producing CD11c(high)CD8α+ dendritic cells (DCs). We characterized a dominant functional Ba...

Background Tsutsugamushi disease is an acute, febrile, infectious disease caused by Orientia tsutsugamushi. Several studies investigating the histopathologic findings of eschars in tsutsugamushi disease reported leukocytoclastic vasculitis and neutrophil infiltration as the major findings. However, these findings may result from secondary changes following tissue necrosis. The histopathologic f...

The title compound, C(24)H(12)BrCl(2)NO(4), was synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 2-chloro-benzoyl chloride. The crystal structure shows that each of the chloro-phenyl rings is inclined at about 60° to the naphthoquinone ring system. The two chloro-phenyl rings adopt a conformation that ensures that chlorine substituents are anti so as to reduce electronic repulsion. An ex...

Generic health status measures are designed to broadly assess the concepts of health, disability, and quality of life. Although generic health status measures are often less responsive to changes in specific conditions than disease-specific instruments, they are important for broad comparisons of the relative impact of different conditions or treatments on the health of the population. The shor...
