BACKGROUND Severe complications associated with EV71 infections caused many infants death. However, the pathogenesis of EV71 infection in the severe cases remained poorly understood. METHODS In this study we collected plasma and cerebrospinal fluid (CSF) specimens drawn in the acute and/or recovery phases from EV71-infected individuals, and plasma(More)
Zinc (Zn) nutrition affects wheat yield and the health of humans who consume wheat grain. This study determined: 1) how distributions of roots and available Zn (DTPA-Zn) in soil affect the Zn content of wheat plants; and 2) the concentrations of shoot Zn and soil DTPA-Zn needed to obtain high yields and the “target value” of grain Zn biofortification (45 mg(More)
Background: Acute diarrhea is one of the most serious problems in global public health that causes considerable morbidity and mortality worldwide. Human caliciviruses (HuCV) including norovirus (NoV, genogroup GI and GII) and sapovirus (SaV), is a leading cause of acute sporadic diarrhea in individuals across all age groups. However, few studies had been(More)
Adequate zinc (Zn) in maize (Zea mays L.) is required for obtaining Zn-enriched grain and optimum yield. This study investigated the impact of varying Zn fertilizer placements on Zn accumulation in maize plant. Two pot experiments with same design were conducted to investigate the effect of soil Zn heterogeneity by mixing ZnSO4·7H2O (10 mg Zn kg−1 soil on(More)
Hepatitis A virus (HAV) is a hepatotropic picornavirus that causes acute liver disease worldwide. Here, we report on the identification of a novel hepatovirus tentatively named Marmota Himalayana hepatovirus (MHHAV) in wild woodchucks (Marmota Himalayana) in China. The genomic and molecular characterization of MHHAV indicated that it is most closely related(More)
