Background: The vitamin D pathway contributes to the microbicidal activity of macrophages against infection. In addition to induction of this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part of a network of pro-inflammatory cytokines. The aim of this study was to evaluate single-nucleotide polymorphisms (SNPs) in the components of the vitamin D pathway and associated cytokine genes that could be related to resistance or susceptibility to American tegumentary leishmaniasis (ATL).

Three fluorescent Zn coordaintion polymers (CPs) have been synthesized from the reactions of Zn(NO3)2∙6H2O, benzene-1,4-dicarboxylic acid (1,4-H2bdc), and angular carbazole-derived bispyridyl ligands (Cz-3,6-bpy or Cz-Pr-3,6-bpy). CPs 1-3 all adopt similar two-dimensional (2D) ring-and-rod layer structures, described as topologically 4-connected 2∙65 nets where the Zn(II) centers act as 4-connected nodes. CPs 1 and 2 are a pair of solvent-mediated supramolecular isomers where the former shows a two-fold interlocked 2D → 2D polyrotaxane-like entangled net and the latter reveals a four-fold interpenetrated 2D → 3D polyrotaxane entanglement.

We describe synthesis of BN-doped nanographene containing five phenylene units, boron and nitrogen atoms with both alternating ortho-disposition as well as direct B-N connection. Resulting BN doped nanographene exhibits blue fluorescence at 441 nm with extraordinary narrow fluorescence peak with full width at half maximum (FWHM) = 10-11 nm. Crystallography reveals supramolecular organization of this compound in the crystal phase.

As a potential corridor connecting Southwest Asia with western and northern Europe, the Armenian Highlands and southern Caucasus hold great potential for increasing our understanding of Upper Paleolithic behavioral and cultural variability. However, given the dearth of Upper Paleolithic sites, we lack the data necessary to answer basic questions regarding the timing and nature of the Upper Paleolithic in this region. Solak-1 is an open-air site located along the upper Hrazdan Valley (1635 m above sea level) in central Armenia.
