hina has experienced unprecedented economic growth over the past two decades, accompanied by the development of large-scale industries and services. In the course of this expansion, medium-sized cities and small towns have sprung up around the larger cities, forming city clusters, often with similar or interdependent economies. The development of city(More)
China is taking major steps to improve Beijing's air quality for the 2008 Olympic Games. However, concentrations of fine particulate matter and ozone in Beijing often exceed healthful levels in the summertime. Based on the US EPA's Models-3/CMAQ model simulation over the Beijing region, we estimate that about 34% of PM 2.5 on average and 35–60% of ozone(More)
BACKGROUND Epidemiologic evidence for a causative association between black carbon (BC) and health outcomes is limited. OBJECTIVES We estimated associations and exposure-response relationships between acute respiratory inflammation in schoolchildren and concentrations of BC and particulate matter with an aerodynamic diameter of ≤ 2.5 μm (PM2.5) in ambient(More)
As emerging tick born rickettsial diseases caused by A. phagocytophilum and E. chaffeensis, anaplasmosis and ehrlichiosis have become a serious threat to human and animal health throughout the world. In particular, in China, an unusual transmission of nosocomial cases of human granulocytic anaplasmosis occurred in Anhui Province in 2006 and more recent(More)
Light intensity affects photosynthetic carbon (C) fixation and the supply of carbon to roots. To evaluate interactions between carbon supply and phosphorus (P) supply, effects of light intensity on sucrose accumulation, root growth, cluster root formation, carboxylate exudation, and P uptake capacity were studied in white lupin (Lupinus albus L.) grown(More)
Since 2007, many cases of fever, thrombocytopenia and leukopenia syndrome (FTLS) have emerged in Henan Province, China. Patient reports of tick bites suggested that infection could contribute to FTLS. Many tick-transmitted microbial pathogens were tested for by PCR/RT-PCR and/or indirect immunofluorescence assay (IFA). However, only 8% (24/285) of samples(More)
In 2011, human coxsackievirus B5 (CVB5) caused an outbreak of viral encephalitis in Henan, China. Complete genome sequence analysis based on two isolates showed that the 5′ half of the genome (nt 1-4540) had high similarity (>97 %) to that of CVB5 strain GU376747, and the 3′ half (nt 4700–7402) showed high similarity (>96 %) to that of human coxsackievirus(More)
BACKGROUND In 2007, a novel bunyavirus was found in Henan Province, China and named fever, thrombocytopenia and leukocytopenia syndrome virus (FTLSV); since then, FTLSV has been found in ticks and animals in many Chinese provinces. Human-to-human transmission has been documented, indicating that FTLSV should be considered a potential public health threat.(More)
Positive below-ground interactions (facilitation) should be more pronounced when resources limit crop growth, according to the stress-gradient hypothesis. Our aim was to test this hypothesis for intercropped durum wheat and faba bean along a P-fertilizer gradient. A field experiment was conducted in a long-term P-fertilizer trial with three rates of(More)
