Does intracranial injection of PEG-PEI/ROCK II-siRNA improve cognitive impairment in a mouse model of Alzheimer 's disease?
Intracranial injection of PPRS improved the cognitive impairments of SAM mice, and this improvement may have been mediated by enhancement of ChAT activity in the hippocampus.
In the majority of cases, conventional two-dimensional ultrasound could be used to differentiate undescended testes from reactive lymph nodes with acceptable accuracy. Although the incremental value of elastography is limited, this technique might have a role in some specific cases.
