BACKGROUND The neurobiological basis of stress and anxiety in primates remains poorly understood. In this study, we examined the neural response to a naturalistic social stressor: maternal separation. We used rhesus monkeys as an animal model because of their close phylogenetic affinity with humans. METHODS Six juvenile rhesus monkeys received [(18)F]-fluorodeoxyglucose positron emission tomo...

This study shows that a range of separation applications for the MFM family metal–organic frameworks (MOFs) can be expanded to include effective separations Xe/Kr binary gas mixtures. The copper paddlewheel-based, isoreticular MOFs has shown previously an excellent performance CO2/CH4 and CO2/N2 separations. proposed new function aids development this MOF series into multiuse functional materia...

Relative levels of ribosomal proteins were quantified in crude cell lysates using mass spectrometry. A method for quantifying cellular protein levels using macromolecular standards is presented that does not require complex sample separation, identification of high-responding peptides, affinity purification, or postgrowth modifications. Perturbations in ribosomal protein levels by overexpressio...
