A large cohort study of 74,828 benzene-exposed and 35,805 unexposed workers employed between 1972 and 1987 in 12 cities in China were followed to determine mortality from all causes and the incidence of lymphohematopoietic malignancies and other hematologic disorders. Benzene-exposed study subjects were employed in a variety of occupations, including(More)
A large cohort of 74,828 benzene-exposed and 35,805 nonexposed workers employed between 1972 and 1987 in 12 cities in China was followed to determine mortality from all causes. Benzene-exposed study subjects were employed in a variety of occupations including coating applications, and rubber, chemical, and shoe production. Mortality was slightly increased(More)
We present a validation study of a quantitative retrospective exposure assessment method used in a follow-up study of workers exposed to benzene. Assessment of exposure to benzene was carried out in 672 factories in 12 cities in China. Historical exposure data were collected for 3179 unique job titles. The basic unit for exposure assessment was a(More)
nificantly improved therapies to patients for the functional restoration of damaged or degenerated bone. The overall goal of these efforts is to develop bone graft substitutes that combine the availability and structural integrity of allograft bone with the osteogenic properties of autograft bone. The strategies being developed are numerous and diverse,(More)
Approximate strategies are crucial in daily human life. The studies on the "difficulty effect" seen in approximate complex arithmetic have long been neglected. Here, we aimed to explore the brain mechanisms related to this difficulty effect in the case of complex addition, using event-related potential-based methods. Following previous path-finding studies,(More)
In this Article, the legend of Figure 3 is incorrect: Grand averaged event-related potentials (ERPs) elicited at the midline, lateral electrodes during small split and medium split arithmetic. Grand averaged event-related potentials (ERPs) elicited at the midline, lateral electrodes during middle split and large split arithmetic. This work is licensed under(More)
The present study assessed negative emotions associated with the traumas of infertility and child rearing (child's disability or death) and the correlates of duration of trauma. The widely used Chinese Mental Health Scale was used to assess negative emotions in 294 individuals who experienced the aforementioned traumas and 124 who did not (control group).(More)
