tional settling or meridional circulation). Cosmic-ray nucleosynthesis models and observations of interstellar clouds indicate that the primordial ratio, f(Li), in the protoplanetary matter could have been as high as 0.3±0.5, which in turn would allow either the possibility of some Li depletion in the star or the ingestion of planets with even smaller mass. In this scenario we have assumed that...
Interleukin 17 (IL-17) is a cytokine associated with inflammation, autoimmunity and defense against some bacteria. Here we show that IL-17 can promote autoimmune disease through a mechanism distinct from its proinflammatory effects. As compared with wild-type mice, autoimmune BXD2 mice express more IL-17 and show spontaneous development of germinal centers (GCs) before they increase production ...
The microstructural evolution of Dy₂O₃-TiO₂ powder mixtures during ball milling and post-milled annealing was investigated using XRD, SEM, TEM, and DSC. At high ball-milling rotation speeds, the mixtures were fined, homogenized, nanocrystallized, and later completely amorphized, and the transformation of Dy₂O₃ from the cubic to the monoclinic crystal structure was observed. The amorphous transf...
The reaction of Dy(NO(3))(3)·6H(2)O with the ligand 2-((1-hydroxybutan-2-ylimino)methyl)phenol (H(2)L, ) generates the nonanuclear compound [Dy(9)L(8)(μ(3)-OH)(8)(μ(4)-OH)(2)(CH(3)OH)(8)](OH)(CH(3)OH)(3) (Dy(9)), whose single-crystal X-ray structure reveals the presence of two square pyramidal pentanuclear units assembled via the apical metal center. The square pyramidal core of a previously re...
We examine the spin-wave (SW) dynamics of Dy/Y multilayers in order to separate the contribution of the Dy-Y interface from that of bulk Dy. The SW frequencies and intensities of bulk Dy are determined analytically. When the Dy layers in a multilayer geometry are decoupled, the SW dispersion relations are discontinuous with discrete excitations. With a Ruderman-Kittel-Kasuya-Yosida (RKKY) inter...
The title centrosymmetric dinuclear dysprosium(III) complex, [Dy(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)] or [Dy(L)(3)phen](2), is comprised of six 3,4-dimethoxy-phenylacetate (L) anions, two 1,10-phenanthroline (phen) mol-ecules and two Dy(III) ions. The Dy(III) atom is nine-coordinated by seven O atoms from five L ligands and two N atoms from the phen mol-ecules. The L ligands are coordinated...
not seek treatment. Untreated chlamydial infection can persist for a year or more, leading to sustained risks of transmission.6 In 1988, the New York State Department of Health’s Bureau of Sexually Transmitted Disease (STD) Control initiated a screening program to assess the prevalence of chlamydial infection among women attending public health clinics throughout the state. In this article, we ...
In the 1960s, the thesis that dietary cholesterol contributes to blood cholesterol and heart disease risk was a rational conclusion based on the available science at that time. Fifty years later the research evidence no longer supports this hypothesis yet changing the dietary recommendation to limit dietary cholesterol has been a slow and at times contentious process. The preponderance of the c...
ING1 gene, the founding member of the ING tumor suppressor family, was originally identified through subtractive hybridization between normal mammary epithelial cells and breast cancer cell lines, and subsequent in vivo selection of genetic suppressor element that displayed oncogenic features. The four additional members of the ING family (ING2-5) were recently identified and all the gene produ...
