Aims: In order to clarify hepato-protective actions of estrogen, we examined the progress of carbon tetrachloride (CCl)-induced acute liver injury (ALI) in sham and ovariectomized (ovx) mice and the effects of dimethylthiourea (DMTU), a hydroxyl radical scavenger, and meloxicam (Melo), a selective cox-2 inhibitor, on the development of CCl-induced ALI.
Main Methods: Female C57BL/6 J mice weighing 15-20 g were performed sham or ovx operation at 8 weeks of age. Blood and liver samples were collected 15 and 24 h after CCl administration.
Only humans possess the faculty of language that allows an infinite array of hierarchically structured expressions (Hauser et al., 2002; Berwick and Chomsky, 2015). Similarly, humans have a capacity for infinite natural numbers, while all other species seem to lack such a capacity (Gelman and Gallistel, 1978; Dehaene, 1997).

Ovx or sham operation was performed in C57BL/6J wild-type female mice of eight weeks of age. Sham mice and ovx mice were treated with DOXY (240 mg/kg ip) 8 weeks after the operation, 30 min after apocynin (5 mg/kg) or saline administration.

We investigated the clinicopathological significance of epithelial cell adhesion molecule (EpCAM) expression and the utility of EpCAM as a potential therapeutic target.
Methods: The relationship between EpCAM expression and clinicopathological factors was examined by immunohistochemistry in 74 patients with resectable ESCC.
