The physical manifestation of learning and memory formation in the brain can be expressed by strengthening or weakening of synaptic connections through morphological changes. Local actin remodeling underlies some forms of plasticity and may be facilitated by local β-actin synthesis, but dynamic information is lacking. In this work, we use single-molecule in situ hybridization to demonstrate tha...

BACKGROUND Pharmacological MRI (phMRI) is a neuroimaging technique where drug-induced hemodynamic responses can represent a pharmacodynamic biomarker to delineate underlying biological consequences of drug actions. In most preclinical studies, animals are anesthetized during image acquisition to minimize movement. However, it has been demonstrated anesthesia could attenuate basal neuronal activ...

We agree with Litwak and Levin that clinical trials are the best way to determine human health effects of dietary components. However, nonhuman primates offer experimental control and an anatomically and physiologically representative animal model and have inherent value in translational research. Details regarding study methodology are available on request, as they were at the time of review. ...

125I protein labelling of oligo(dT)-selected RNA from feline calicivirus (FCV)-infected cells revealed that the genomic and 2.4 kb subgenomic RNAs of FCV are linked to a 15 kDa protein (VPg). Proteinase K treatment of FCV RNA, to remove VPg, led to a decrease in the translatability of the RNA, but there was no obvious change in the site of RNA initiation. Addition of the cap analogue 7-methylGT...
