    “…INTRODUCTION: The objective of this study was to clarify secular changes in the prevalence and cumulative incidence of vertebral fractures (VFx) among the general inhabitants of Miyama, a rural Japanese community. METHODS: A cohort of 1,543 inhabitants aged 40–79 years was established using resident registration in 1989. …”

    “…[Image: see text] A series of palladium acyclic diaminocarbene (ADC) complexes of the type cis-[(R(1)NH)(R(2))methylidene]PdCl(2)(CNR(1)) [R(1) = 2,4,6-(CH(3))(3)C(6)H(2): R(2) = NC(5)H(10) (2); NC(4)H(8) (3); NC(4)H(8)O (4)] were used not only to perform the C(sp(2))–C(sp) Hiyama coupling between aryl iodide and triethoxysilylalkynes but also to subsequently carry out the one-pot tandem Hiyama alkynylation/cyclization reaction between 2-iodophenol and triethoxysilylalkynes, giving a convenient time-efficient access to the biologically relevant benzofuran compounds. …”
