(η6-Benzophenone)(η5-pentamethylcyclopentadienyl)ruthenium(II) tetraphenylborate
Acta Crystallographica Section E, 2009 The structure of the title compound, [Ru(C10H15)(C13H10O)](C24H20B), consists of discrete [Cp*Ru(II)benzophenone] cations and tetraphenylborate anions (Cp* = pentamethylcyclopentadienyl). Tethering the Cp*Ru group to one aryl ring of benzophenone results

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy
Advanced Healthcare Materials, EarlyView.Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.
