BACKGROUND Benzo[a]pyrene (B[a]P) is a common environmental and foodborne pollutant. Although the carcinogenicity of high-dose B[a]P has been extensively reported, the effects of long-term B[a]P exposure at lower environmental doses on cancer development are less understood. OBJECTIVES We investigated the impact of B[a]P on human hepatocellular carcinoma(More)
Iodine deficiency disorders were prevalent in China until the introduction of universal salt iodization in 1995. Concerns have recently arisen about possible excess iodine intake in this context. To document iodine intake and the contribution from iodized salt in China, we surveyed dietary iodine intake during China's nationally representative 2007 total(More)
BACKGROUND Inappropriate use of antibiotics in swine feed could cause accelerated emergence of antibiotic resistance genes, and agricultural application of swine waste could spread antibiotic resistance genes to the surrounding environment. OBJECTIVES We investigated the distribution of plasmid-mediated quinolone resistance (PMQR) genes from swine(More)
BACKGROUND Acute gastrointestinal illness (AGI) is an important public-health problem worldwide. Previous national studies of the incidence of AGI in China were performed decades ago, and detailed information was not available. This study therefore sought to determine the magnitude, distribution, and burden of self-reported AGI in China. METHODS(More)
Peptides inhibiting angiotensin-I converting enzyme (ACE, EC. 3.4.15.1) are possible cures of hypertension. Food-derived ACE-inhibitory peptides are particularly attractive because of reduced side effects. Previously, we reported ACE-inhibitory activity of grass carp protein hydrolysates. In this work, we report steps for purifying the ACE-inhibitory(More)
The efficient delivery of photons from light sources to photonic circuits is central to any fibre-optic or integrated optical system. Coupling light emitters to optical fibres or waveguides determines the photon flux available in, and therefore the performance of, photonic devices used in applications such as optical communication and information(More)
A Total Diet Study (TDS) can be a complementary approach to traditional monitoring and surveillance programs, which instead of focusing on compliance is designed to provide a solid basis for calculating population dietary exposure and assessing potential impact on public health. A TDS includes the selection of foods based on food consumption data to(More)
BACKGROUND Ribosome display technology has provided an alternative platform technology for the development of novel low-cost antibody based on evaluating antibiotics derived residues in food matrixes. METHODOLOGY/PRINCIPAL FINDINGS In our current studies, the single chain variable fragments (scFvs) were selected from hybridoma cell lines against(More)
BACKGROUND Haff disease is unexplained rhabdomyolysis caused by consumption of fishery products in the previous 24 h. It was first identified in Europe in 1924 but the condition is extremely rare in China. Here we describe a past outbreak of acute food borne muscle poisoning that occurred in Guangdong Province (South China) in 2009. METHODS The first full(More)
Zearalenone (ZEA), a mycotoxin produced by Fusarium fungi, is found in cereal crops. Although the toxic effects of ZEA have been well characterized, the mechanism is not clear, especially with respect to the oxidative damage. In this study, we determined superoxide dismutase (SOD) and malondialdehyde (MDA) levels as indexes of oxidative damage caused by ZEA(More)
