This paper reviews the anatomy of the primary organs (kidney, liver, and spleen) responsible for nanoparticle bioelimination and the components of the innate immune system (complement system and scavenger receptors) that indirectly and directly recognize nanoparticles as foreign.

The β2-adrenergic receptor (β2-AR) agonist [3H]-(R,R′)-methoxyfenoterol was employed as the marker ligand in displacement studies measuring the binding affinities (Ki values) of the stereoisomers of a series of 4′-methoxyfenoterol analogs in which the length of the alkyl substituent at α′ position was varied from 0 to 3 carbon atoms.

Here we explored a possibility of designing a serum stability tag made of natural amino acids. We observed that a diproline motif (-Pro-Pro-) shows remarkable stability against serum endopeptidases.

Here, alcohol-preferring (P) and alcohol-nonpreferring (NP) rats systematically bred from heterogeneous stock Wistar rats for differential alcohol drinking behavior were compared with Wistar rats to determine whether genetic divergence and consequent morphological and neurochemical variation affect the brain’s response to binge EtOH treatment.

The relative utility of single biomarkers compared to biomarker panels is discussed, along with paradigms for biomarker development, the latter in the context of three large-scale biomarker consortia, the Critical Path Predictive Safety Testing Consortium (PSTC), the NCI Early Detection Research Network (EDRN) and the Alzheimer’s Disease Neuroimaging Initiative (ADNI).

Here we describe the use of a neurotoxin, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), which produces a nigrostriatal lesion to elucidate the distinct contributions of LOX isozymes to neurodegeneration related to PD.
