導師學校
威廉姆斯學院Williams College
Charles導師是威廉姆斯學院化學講席終身正教授,在威廉姆斯學院設有毒理學、生物化學等課程,曾任威廉姆斯學院化學系主任、生物化學與分子生物學項目主任,擁有康奈爾大學生物化學博士學位。
Charles導師的研究結合遺傳學、蛋白質組學和生化分析,了解SOS基因產物的綜合活性如何為細胞對DNA損傷的反應提供幫助。他的研究獲得了美國國家科學基金會和美國國立衛(wèi)生研究院的大力支持,聚焦DNA損傷的SOS修復,在國際知名期刊發(fā)表論文數十篇。
Prof.Charles’s teaching experience includes program in biochemistry and molecular biology;team-taught,interdisciplinary courses on AIDS,globalism,and the renovation of the Thompson Science Buildings and addition of the Morley Science Labs that,at the time,was the largest capital project in the college’s history.He has also co-taught a science camp for local elementary school students and teachers and mentored dozens of students in your laboratory’s study of DNA repair.He served as director of the Bronfman Science Center and chair of the Science Committee for more consecutive years than one would think humanly possible.
The research in his laboratory focuses on the SOS response in the bacterium Bacillus subtilis.Using a combination of genetic,proteomic,and biochemical analyses
his group is trying to understand how the integrated activities of the SOS gene
products provide for the cell’s response to DNA damage.

項目介紹
本項目將帶領學生學習生物標志物、毒性標準和評價、在生物體內的代謝途徑、化學反應、以及對機體的影響,并深入到毒素對DNA的影響與致病性。學生將通過項目了解化學物質毒理學經典理論概念,毒性評價及其與生命系統(tǒng)的相互作用,思考在環(huán)境、公共衛(wèi)生、食品安全等各個領域的應用。課程中將列舉大量化學物質實例,逐一剖析它們的化學性質以及危險因素。在項目結束時提交報告,進行成果展示。
個性化研究課題參考:水飛薊素對丙烯酰胺所致PC12細胞氧化損傷的保護作用、不同種蘆薈植物化學物組成及抗紫外損傷機理探究、氯化鎘、硫酸鋅和亞硒酸鈉的體外細胞毒性
This program will lead students to learn biomarkers,toxicity criteria and evaluation,metabolic pathways in organisms,chemical reactions,and effects on the body,and in-depth into the effects of toxins on DNA and pathogenicity.Through the project,students will understand the classical theoretical concepts of chemical toxicology,toxicity evaluation and its interaction with living systems,and think about the application in various fields such as environment,public health and food safety.A large number of examples of chemicals will be presented and their chemical properties and risk factors will be analyzed one by one.Students will understand the classic theories and concepts of biochemical toxicology,toxicity and its interaction with life systems through the project,and submit a report at the end of the project to demonstrate their results.
Suggested Future Research Fields:Protective effect of silymarin on oxidative damage of PC12 cells induced by acrylamide,Study on the composition of different kinds of aloe phytochemicals and their anti-ultraviolet damage mechanism,In vitro cytotoxicity of cadmium chloride,zinc sulfate and sodium selenite
項目背景
偵探小說女王英國作家阿加莎的偵探小說之所以極具魅力,很大程度上與她在藥房的工作經歷和對化學物毒性的深刻了解密不可分。毒理學之父帕拉塞爾蘇斯提到:“萬物皆毒物,因為一切物質皆具毒性。只有劑量決定一件事物不是毒物”?,F代毒理學是一門基于化學、生理學、生物學、藥理學、病理學理論,以流行病學和臨床學方法,研究外源因素對生物系統(tǒng)的毒性反應和機制,對毒性進行科學定性定量評價的科學。毒理學的事實是否果真如此?如何鑒定毒性?不同毒物是否都以同種方式產生毒性?毒性在人體內如何處置與代謝?哪些生化機制可以對抗毒性?這些問題將在項目中逐一得到解答。
