Substitution Chemistry of Ruthenium Clusters with the Diphosphine Ligands: 4,5-Bis(Diphenylphosphino)-4-Cyclo-Penten-1,3-Dione (bpcd), (Z)-Ph₂PCH=CHPP₂ and 3,4-Bis(Diphenylphosphino)-5-Methoxy-2(5H)-Furanone (bmf)

Autor: Shen, Huafeng

The chemistry of transition metal clusters has been a fast developing area of organometallic research in recent years. Compared to mononuclear metal complexes, polynuclear clusters offer more opportunities to study cooperative effects and electron re

Low bone mineral density linked to colorectal adenomas: a cross-sectional study of a racially diverse population

Autor: Gowda, Shilpa, Lipka, Seth, Davis-Yadley, Ashley H., Shen, Huafeng, Silpe, Jeffrey, White, Andy, Satler, Sam, Luebbers, Dustin, Statler, James, Zheng, Anna, Elder, Joshua, Abraham, Albin, Viswanathan, Prakash, Mustacchia, Paul

Epidemiologic studies suggest that lower bone mineral density (BMD) is associated with an increased risk for colorectal adenoma/cancer, especially in postmenopausal women. The aim of this study is to investigate the association between osteopenia and
