P Carbonnelle et al.
Toxicology and applied pharmacology, 132(2), 220-226 (1995-06-01)
Decreased interleukin-1 (IL-1) production by mononuclear phagocytes has been shown to contribute to benzene myelotoxicity in animals. The study presented here was designed to examine the relevance of this mechanism in humans. Fresh human blood monocytes were exposed to 0.001-10
Yaqi Hu et al.
Biosensors & bioelectronics, 47, 45-49 (2013-04-03)
A novel light "on-off" photoelectrochemical sensing for the sensitive determination of hydroquinone was developed based on the porphyrin-functionalized Au nanoparticles on graphene (porphyrin/AuNPs/graphene). Gold nanoparticles (AuNPs) were firstly modified onto graphene sheets using NaBH4 as reductant and the porphyrin/AuNPs/graphene nanocomposites
