Elderly females, particularly those carrying the apolipoprotein E (ApoE)-ε4 allele, have a higher risk of developing Alzheimer's disease (AD). However, the underlying mechanism for this increased susceptibility remains unclear. In this study, we investigated the effects of the ApoE genotype and gender on the proteome of synaptosomes. We isolated(More)
The content of carotenoids, chlorophylls, phenolics, and tocols in pistachios ( Pistacia vera L.) has not been methodically quantified. The objective of this study was to first optimize extraction protocols for lipophilic nutrients and then quantify the content of two phenolic acids, nine flavonoids, four carotenoids, two chlorophylls, and three tocols in(More)
It is the first time to extract polysaccharides (CVPs) from Catathelasma ventricosum. The antihyperglycemic and antioxidant activity of CVPs in streptozotocin-induced diabetic mice were examined. Compared with untreated diabetic mice, the administration of CVPs for 30 days caused a significant decrease in the concentrations of blood glucose, total(More)
Post-translational modifications (e.g., ubiquitylation) of histones play important roles in dynamic regulation of chromatin. Histone ubiquitylation has been speculated to directly influence the structure and dynamics of nucleosomes. However, structural information for ubiquitylated nucleosomes is still lacking. Here we report an alternative strategy for(More)
Se-polysaccharide from Catathelasma ventricosum (SPC-2) was purified by DEAE-52 and Sephadex G-100 column chromatography. The average size of SPC-2 was 1.6×10(5) Da, and it was mainly composed of glucose (87.4%) with the conformation of β-pyran ring. The branched structure of SPC-2 was proved intuitively by atomic force microscope (AFM). The antidiabetic(More)
Lysozyme from hen egg white is a well-known antimicrobial protein with high ratio of hydrophobic and positively charged amino acid residues. In order to explore functional bioactivities of enzymatic hydrolysates of lysozyme, the protein was subjected to a simulated gastrointestinal digestion and the resulting hydrolysate (LPH2) showed a strong competitive(More)
The formation of soluble and insoluble complexes between ovalbumin (OVA) and gum arabic (GA) polysaccharide was investigated under specific conditions (pH 1.0-7.0; temperature 4-55 °C; NaCl concentration 0-60mM; total biopolymer concentration 0.05-3.0 wt%) by turbidimetric analysis. For the 2:1 OVA:GA ratio and in the absence of NaCl, soluble and insoluble(More)
OBJECTIVE To describe the prevalence and characteristics of mental disabilities in China. METHODS The data from the Second National Sample Survey on Disability were analyzed with descriptive epidemiological method and the overall prevalence rates of mental disabilities were statistically calculated. RESULTS Among 2 526 145 respondents, 15 155 of them(More)
