OBJECTIVE To determine if HT-1001, an extract of American ginseng, affects scopolamine-induced memory and performance deficits in a spatial learning task, alters brain concentrations of aminergic neurotransmitters, and alters choline uptake in synaptosome preparations. DESIGN Animal study. ANIMALS 48 Sprague Dawley rats. INTERVENTIONS Long-term oral(More)
p53 has a crucial role in governing cellular mechanisms in response to a broad range of genotoxic stresses. During DNA damage, p53 can either promote cell survival by activating senescence or cell-cycle arrest and DNA repair to maintain genomic integrity for cell survival or direct cells to undergo apoptosis to eliminate extensively damaged cells. The(More)
This study reports an exploratory analysis of the age of arrival (AoA) effect on the production of second language (L2) prosody. Three groups of Mandarin-speaking immigrants (N=10 in each group) with varying AoA in the United States and ten native speakers of English as controls participated in the study. All participants read a paragraph of English, and(More)
Previous studies showed that children learning a language with an obligatory singular/plural distinction (Russian and English) learn the meaning of the number word for one earlier than children learning Japanese, a language without obligatory number morphology (Barner, Libenson, Cheung, & Takasaki, 2009; Sarnecka, Kamenskaya, Yamana, Ogura, & Yudovina,(More)
The current study examined the age of learning effect on second language (L2) acquisition. The research goals of the study were twofold: to test whether there is an independent age effect controlling for other potentially confounding variables, and to clarify the age effect across L2 grammar and speech production domains. The study included 118(More)
The count-mass distinction often served as a test case for asking how syntax and semantics are related, whether knowledge of one helps the acquisition of the other. Virtually no studies examined this distinction in classifier languages which supposedly lack the distinction. However, Cheng and Sybesma (1998) argued Mandarin as a classifier language encodes(More)
