Distinguishing Macrophage Activation States by Mass Spectrometry
… assuming various roles based on chemical and/or physical cues, and can reversibly shift between these so-called activation states. Concurrently, the technique of immunohistochemistry is used to gain spatial information on activated macrophages on tissue sections. The aim of this work was to find …

The Breakup Project: using evolutionary theory to predict and interpret responses to romantic relationship dissolution
… for attracting a mate (e.g., resource display, physical cues), attaining a mate (e.g., intrasexual competition), and keeping a mate (e.g., competitor derogation, emotional manipulation). However, this evolutionary model of human pair bonding has not fully addressed relationship termination. If …
