Description: The Handbook of Nanotoxicology, Nanomedicine and Stem Cell Use in Toxicology provides an insight into the current trends and future directions of research in these rapidly developing scientific fields. Written by leading scientists and experts, the Handbook will be of interest to various scientific disciplines including toxicology, medicine,(More)
Chemoprevention that impedes one or more steps in carcinogenesis, via long-term administration of naturally occurring or synthetic compounds, is widely considered to be a crucial strategy for cancer control. Selenium (Se) has chemopreventive effects, but its application is limited due to a low therapeutic index as shown in numerous animal experiments. In(More)
Shadoo is a glycoprotein expressed in the adult brain that is an interacting protein of prion protein; however, its function remains to be determined. To elucidate its role in prion pathogenesis, we generated transgenic mice overexpressing wild-type (wt) Shadoo driven by the murine PrP promoter. Expression of the murine Sprn transgene significantly(More)
Celastrol, also named as tripterine, is a pharmacologically active ingredient extracted from the root of traditional Chinese herb Tripterygium wilfordii Hook F with potent anti-inflammatory and anti-tumor activities. In the present study, we investigated the effects of celastrol on ulcerative colitis-related colorectal cancer (UC-CRC) as well as CRC in vivo(More)
We sought to evaluate the safety and efficacy of available biologics that inhibit T-cell migration by blocking α4β7 integrins in inflammatory bowel diseases. The aim of this study is to evaluate whether Crohn disease (CD) patients receiving either vedolizumab or natalizumab have any different effect in CD Activity Index (CDAI). Using Medline, Excerpta(More)
The present study aimed to observe the effect of rat bone marrow mesenchymal stem cells (MSCs) in vitro on hepatic stellate cell (HSC) RhoA signaling factors and the expression of the cell cycle regulators P27 and cyclin D1. Rat HSC-T6 and fibroblast cells were divided into control, negative control and MSC experimental groups. The cell proliferation rate(More)
Cloned pigs generated by somatic cell nuclear transfer (SCNT) show a greater ratio of early abortion during mid-gestation than normal controls. X-linked genes have been demonstrated to be important for the development of cloned embryos. To determine the relationship between the expression of X-linked genes and abortion of cloned porcine fetuses, the(More)
To gain insight into parthenogenesis in pigs, we report for the first time that using parthenogenetic somatic cells as nuclear donors (PSCNT), the porcine parthenogenetic fetus can develop to gestational day 39. Weight and morphological analysis revealed that PSCNT fetuses were smaller and developmentally retarded when compared to normally fertilized(More)

Selenium participates in the antioxidant defense mainly through a class of selenoproteins, including thioredoxin reductase. Epigallocatechin-3-gallate (EGCG) is the most abundant and biologically active catechin in green tea. Depending upon the dose and biological systems, EGCG may function either as an antioxidant or as an inducer of antioxidant defense(More)
