Recently, researchers have been debating whether children exhibit a universal “noun bias” when learning a first language. The present study compares the proportions of nouns and verbs in the early vocabularies of 24 Englishand 24 Mandarin-speaking toddlers ( M age 5 20 months) and their mothers. Three different methods were used to measure the proportion of(More)
The successful expression of animal or human virus epitopes on the surface of plant viruses has recently been demonstrated. These chimeric virus particles (CVPs) could represent a cost-effective and safe alternative to conventional animal cell-based vaccines. We report the insertion of oligonucleotides coding for a short linear epitope from the VP2 capsid(More)
The endosymbiont-derived Sec-dependent protein sorting pathway is essential for protein import into the thylakoid lumen and is important for the proper functioning of the chloroplast. Two loss-of-function mutants of cpSecA, the ATPase subunit of the chloroplast Sec translocation machinery, were analysed in Arabidopsis. The homozygous mutants were albino and(More)
Evaluating the chromatinized erbB2 gene in nuclei from breast cancer cells expressing varying levels of ErbB2 transcripts, we identified a nuclease-sensitive site within a 0.22 kb region of maximum enhancer activity centered over a conserved 28 bp polypurine(GGA)-polypyrimidine(TCC) mirror-repeat and an adjacent essential Ets binding site (EBS). Promoter(More)
Based on recent information, CD200Fc, a CD200R1 agonist, could attenuate the inflammatory response of microglial cells in autoimmune diseases and neuro-degeneration. However, the exact molecular mechanisms responsible for the anti-inflammatory activity of CD200Fc in microglial cells have not been elucidated. In the present study, we investigated the(More)
Previous studies have shown activation of cyclic AMP response element-binding protein (CREB) family is involved in the retinal ganglion cells (RGCs) protection. However, the function of cyclic AMP response element modulator-1 (CREM-1), one member of the CREB family, is still with limited acquaintance. To investigate whether CREM-1 is involved in RGCs death,(More)
The aim of this meta-analysis is to explore the relationship between plasma total homocysteine (tHcy) levels, serum folic acid, vitamin B12 and vitamin B6 levels, methylenetetrahydrofolate reductase (MTHFR) C677T genotype and risk of pseudoexfoliation glaucoma (PEXG). A systematic search of EMBASE and PubMed of relevant articles was carried out for all(More)
Parkinson's disease (PD) is the common age-related neurodegenerative disorder. Sensitive, noninvasive biomarkers that facilitate PD diagnosis and stage assignment are currently unavailable. This study aims to investigate the potential of 16 previous reported PD-associated miRNAs as novel biomarkers for PD. The expression of 16 serum miRNAs was measured by(More)
BACKGROUND On May 12, 2008, a magnitude 8.0 earthquake struck China's southwestern Sichuan province. Recent studies have identified mental health problems among the survivors, but little is known about the impact of the Sichuan earthquake on the mental health of pregnant women in the area. The main objective was to assess the impact of the Sichuan(More)
Cell cycle re-entry is one of the key processes in neuronal apoptosis. Previous studies have shown that Ski-interacting protein (SKIP) played an important role in cell cycle re-entry. However, its expression and function in optic nerve injury are still with limited acquaintance. To investigate whether SKIP is involved in retinal ganglion cells (RGCs) death,(More)
