Characterization of Microstructural Changes on Biglycan Induced Mice Bone by Low-Field Nuclear Magnetic Resonance.

A NMR spin-spin (T) relaxation technique has been described for determining the porosity, and the bound water distribution in biglycan induced mouse bone and correlate to their mechanical properties. The technique of low-field proton NMR involves spin-spin relaxation and free induction decay (FID) measurements, and the computational inversion methods for decay data analysis. The CPMG T2 relaxation data can be inverted to T relaxation distribution and this distribution then can be transformed to a pore size distribution with the longer relaxation times corresponding to larger pores.

Examining racial differences in diffuse large B-cell lymphoma presentation and survival.

We performed a retrospective cohort analysis of 701 (533 white and 144 black) patients with diffuse large B-cell lymphoma (DLBCL) treated at two referral centers in southern United States between 1981 and 2010. Median age of diagnosis for blacks was 50 years vs. 57 years for whites (p < 0.
