Scientific Correspondence Zinnia. Everybody Needs Good Neighbors

Cells in an organism exist within a social context— the sum of interactions with neighboring cells help to define the nature of each individual. The Zinnia system provides a unique opportunity to study in vitro the interactions between different plant cell types and the consequences for commitment to a particular cell fate. Zinnia is a model system in which mesophyll cells, released from young ...

How Good Does It Need to Be?

H igh-sensitivity cardiac troponin (hs-cTn) assays reportedly allow early definitive triage of patients with possible acute myocardial infarction (AMI). To be confident that one can implement such strategies safely, fastidious data are required. In their paper in this issue of the Journal, Mokhtari et al. (1) build on the protocol included in the European Society of Cardiology guidelines to rul...

Good Markets Make Bad Neighbors

In their manuscript, Corsaro, Hunt, Kroovand Hipple, and McGarrell (2012, this issue) provide a valuable contribution to the literature regarding focused deterrence with an econometric evaluation of the High Point Drug Market Intervention (DMI). By employing a difference-in-difference Poisson panel regression framework, as well as group-based trajectory analyses, these authors examine the High ...

Development of the renal glomerulus: good neighbors and good fences.

The glomerulus of the mammalian kidney is an intricate structure that contains an unusual filtration barrier that retains higher molecular weight proteins and blood cells in the circulation. Recent studies have changed our conception of the glomerulus from a relatively static structure to a dynamic one, whose integrity depends on signaling between the three major cell lineages: podocytes, endot...
