GSID: M4KPucBp_pAJ
TJ Givnish, MHJ Barfuss, B Van Ee, R Riina… - Molecular phylogenetics …, 2014 - Elsevier

… Rates of net species diversification drop sharply with subfamily stem age (y = 2.17 e −0.122 … Based on this, net diversification rates based on stem ages are significantly higher in the two …

Fascin-1 is released from proximal tubular cells in response to calcineurin inhibitors (CNIs) and correlates with isometric vacuolization in kidney transplanted patients.

American journal of translational research

Jacobs-Cachá C, Torres IB, López-Hellín J, Cantarell C, Azancot MA, Román A, Moreso F, Serón D, Meseguer A, Sarró E.
PMID: 28979691
Am J Transl Res. 2017 Sep 15;9(9):4173-4183. eCollection 2017.

Immunosuppression based on calcineurin inhibitors (CNIs) has greatly improved organ transplantation, although subsequent nephrotoxicity significantly hinders treatment success. There are no currently available specific soluble biomarkers for CNI-induced nephrotoxicity and diagnosis relies on renal biopsy, which is costly, invasive...

Whole genome comparison of six Crocosphaera watsonii strains with differing phenotypes.

Journal of phycology

Bench SR, Heller P, Frank I, Arciniega M, Shilova IN, Zehr JP.
PMID: 27007210
J Phycol. 2013 Aug;49(4):786-801. doi: 10.1111/jpy.12090. Epub 2013 Jul 09.

Crocosphaera watsonii, a unicellular nitrogen-fixing cyanobacterium found in oligotrophic oceans, is important in marine carbon and nitrogen cycles. Isolates of C. watsonii can be separated into at least two phenotypes with environmentally important differences, indicating possibly distinct ecological roles...

Application of (119)Sn CPMG MAS NMR for Fast Characterization of Sn Sites in Zeolites with Natural (119)Sn Isotope Abundance.
