Charlene J. Sato's "A Nonstandard Approach to Standard English": A Major Contribution to the Field of Sociolinguistics

In her article, "A nonstandard approach to standard English" (1989), Charlene Sato addresses several issues rerated to the controversy over the use of Hawai'i Creole English (HCE) and standard English (SE) in the crassroom. Opposing an assimilationist perspective and taking a pluralistic position toward language use in society, Sato stresses the importance ofunderstanding the differences between SE and minority, or nonstandard, varieties in legitimizing the educational experience of language minority groups. Sato defends her "nonstandard" approach by showing how a pruralistic perspective can contribute to the school success of minority ranguage students. She bases this view on empirical studies that show minority varieties ofEngrish are different from SE both linguistically and in discourse structure, and thus adjustments in the classroom must be made to accommodate these differences ifchirdren are to be given the opportunity to succeed. Sato also offers suggestions on what teachers can do to contribute toward equal education for minority language speakers. we will summarize Sato,s points and discuss the significance of her article

Tocopheryl Phosphate Inhibits Rheumatoid Arthritis-Related Gene Expression In Vitro and Ameliorates Arthritic Symptoms in Mice

Anti-rheumatoid arthritis (RA) effects of α-tocopherol (α-T) have been shown in human patients in a double-blind trial. However, the effects of α-T and its derivatives on fibroblast-like synoviocytes (FLS) during the pathogenesis of RA remain unclear. In the present study, we compared the expression levels of genes related to RA progression in FLS treated with α-T, succinic ester of α-T (TS), and phosphate ester of α-T (TP), as determined via RT-PCR. The mRNA levels of interleukin (IL)-6, tumor necrosis factor-α (TNF-α), matrix metalloproteinase (MMP)-3, and MMP-13 were reduced by treatment with TP without cytotoxicity, while α-T and TS did not show such effects. Furthermore, intraperitoneal injection of TP ameliorated the edema of the foot and joint and improved the arthritis score in laminarin-induced RA model mice. Therefore, TP exerted anti-RA effects through by inhibiting RA-related gene expression

Intraperitoneal administration of nanoparticles containing tocopheryl succinate prevents peritoneal dissemination

Intraperitoneal administration of anticancer nanoparticles is a rational strategy for preventing peritoneal dissemination of colon cancer due to the prolonged retention of nanoparticles in the abdominal cavity. However, instability of nanoparticles in body fluids causes inefficient retention, reducing its anticancer effects. We have previously developed anticancer nanoparticles containing tocopheryl succinate, which showed high in vivo stability and multifunctional anticancer effects. In the present study, we have demonstrated that peritoneal dissemination derived from colon cancer was prevented by intraperitoneal administration of tocopheryl succinate nanoparticles. The biodistribution of tocopheryl succinate nanoparticles was evaluated using inductively coupled plasma mass spectroscopy and imaging analysis in mice administered quantum dot encapsulated tocopheryl succinate nanoparticles. Intraperitoneal administration of tocopheryl succinate nanoparticles showed longer retention in the abdominal cavity than by its intravenous (i.v.) administration. Moreover, due to effective biodistribution, tumor growth was prevented by intraperitoneal administration of tocopheryl succinate nanoparticles. Furthermore, the anticancer effect was attributed to the inhibition of cancer cell proliferation and improvement of the intraperitoneal microenvironment, such as decrease in the levels of vascular endothelial growth factor A, interleukin 10, and M2-like phenotype of tumor-associated macrophages. Collectively, intraperitoneal administration of tocopheryl succinate nanoparticles is expected to have multifaceted antitumor effects against colon cancer with peritoneal dissemination
