Recombinant adeno-associated viruses (rAAVs) have been tested in humans and other large mammals without adverse events. However, one study of mucopolysaccharidosis VII correction in mice showed repeated integration of rAAV in cells from hepatocellular carcinoma (HCC) in the Dlk1-Dio3 locus, suggesting possible insertional mutagenesis. In contrast, another study found no ...

Plants in tropical regions experience temperature fluctuation only in non-extreme ambient temperatures. Thus, moderate changes in temperatures, which they never experience in their local environments, might be sufficient to manifest the locally hidden phenotype caused by natural mutation. To validate this hypothesis, temperature-treating experiments were performed on Capsicum accessions collected ...

RATIONALE: We recently suggested that dopamine on D1-like receptors is involved in the activation of goal-directed responses and the level of response activation is "reboosted" on the basis of an evaluation process involving D2-like receptors assessing "response efficacy". A main piece of evidence in support of this hypothesis was the ...

When systematic movement errors occur, the brain responds with a systematic change in motor behavior. This type of adaptive motor learning can transfer intermanually; adaptation of movements of the right hand in response to training with a perturbed visual signal (visuomotor adaptation) may carry over to the left hand. While ...
