The purpose of this study was to compare the antioxidant capacities of seven natural pigments including the fat-soluble pigments curcumin, lycopene, lutein and β-carotene and water-soluble pigments--betalain, capsanthin and cyanidin-3-rutinoside relative to a commonly-used synthetic food antioxidant BHA. The antioxidant capacities of seven pigments and BHA(More)
— In intermittently connected sensor networks, wherein sensor nodes do not always have connected paths to the base station, preserving generated data inside the network is a new and challenging problem. We propose to preserve the data items by distributing them from storage-depleted data generating nodes to sensor nodes with available storage space and high(More)
Data generated in sensor networks may have different importance and priority. Different types of data contribute differently for scientists to analyze the physical environment. In a challenging environment, wherein sensor nodes do not always have connected paths to the base station, and not all the data can be preserved inside the network due to severe(More)
INTRODUCTION While three types of hepatitis A vaccines are available in China, little data are available to compare them in terms of early antibody response. We conducted a trial to compare antibody response at 7, 14 and 28 days. METHODS We randomized primary school children in Gansu and Jilin provinces into four groups to receive either (1) Chinese live(More)
The aim of this study was to investigate the antioxidant potential of ampelopsin (APS) by using various methods in vitro, as well as to determine effects of APS on LPS-induced oxidative stress in piglets. The results showed that APS exhibited excellent free radical scavenging by DPPH, ABTS, O2•-, H2O2 and ferric reducing antioxidant power. Ampelopsin also(More)
We previously reported that medium-chain TAG (MCT) could alleviate hepatic oxidative damage in weanling piglets with intra-uterine growth retardation (IUGR). There is a relationship between oxidative status and energy metabolism, a process involved in substrate availability and glucose flux. Therefore, the aim of this study was to investigate the effects of(More)
The occurrence of 13 veterinary drugs were studied in soil fertilized with animal manures in Eastern China. The 69 soil samples were obtained from twenty-three vegetable fields in 2009 and analysed for selected veterinary drugs by HPLC-MS/MS at soil depths of 0-20, 20-40 and 40-60 cm, and two additional samples were re-analysed from an earlier study from(More)
Rodents act as seed predators and dispersers and play an important role in the regeneration of plants. Seed production and rodent abundance may influence caching rodents’ decision to consume or cache seeds. We studied how did seed production and rodent abundance co-influence seed predation and dispersal by rodents in the mast seed years (2011 and 2013) and(More)
OBJECTIVE A new simple RT-LAMP method was applied to detect measles virus nucleic acid and compared with nest-RT-PCR. METHODS Compare the detection rate of the RT-LAMP method with that of nest-RT-PCR by detecting measles virus nucleic acid from measles virus and clinical samples. RESULTS The nucleic acid positive rates of all 23 strains of measles virus(More)
