“This study examined the neural basis underlying the sequential involvement of sentence processing and determined the point at which the processing cost for an object-initial sentence was observed. We presented each phrase in a Japanese object-initial sentence to Japanese participants one by one using an event-related functional MRI technique and compared with our previous subject-initial experiment. We found that the left lingual gyrus was activated upon presentation of the first noun phrases, and the left inferior frontal gyrus upon presentation of the second noun phrases.

Our results suggest that the syntactic complexity of an object-initial sentence is processed by the human brain upon verb recognition.

“The aim of this study was to evaluate adverse effects of multiwalled carbon nanotubes (MWCNT), produced for industrial purposes, on the human epithelial cell line A549. MWCNT were dispersed in dipalmitoyl lecithin (DPL), a component of pulmonary surfactant, and the effects of dispersion in DPL were compared to those in two other media: ethanol (EtOH) and phosphate-buffered saline (PBS). Effects of MWCNT were also compared to those of two asbestos fibers (chrysotile and crocidolite) and carbon black (CB) nanoparticles, not only in A549 cells but also in mesothelial cells (MeT5A isothipendyl human cell line), used as an asbestos-sensitive cell type. MWCNT formed agglomerates on top of both cell lines (surface area 15-35 m2) that were significantly larger and more numerous in PBS than in EtOH

and DPL. Whatever the dispersion media, incubation with 100 g/ml MWCNT induced a similar decrease in metabolic activity without changing cell membrane permeability or apoptosis. Neither MWCNT cellular internalization nor oxidative stress was observed. In contrast, asbestos fibers penetrated into the cells, decreased metabolic activity but not cell membrane permeability, and increased apoptosis, without decreasing cell number. CB was internalized without any adverse effects. In conclusion, this study demonstrates that MWCNT produced for industrial purposes exert adverse effects without being internalized by human epithelial and mesothelial pulmonary cell lines.”
