There is currently no biomarker or pharmacological therapy available for the treatment of early aortic valve disease and this is largely due to our limited understanding of the disease mechanisms. One potential mechanism of valve repair and potentially early valve disease is endothelial-to-mesenchymal transformation (EndMT), the initiating event of valvulogenesis. Our preliminary work has shown that extracellular matrix (ECM) composition that mimics diseased valve conditions strongly stimulates mesenchymal transformation. EndMT may be a mechanism for signaling valve interstitial cells toward either valve regeneration or disease and growing evidence indicates that communication between the interstitial cells and the endothelial cells is essential for valve homeostasis. Unfortunately, there is currently no known unifying mechanism of valve disease that connects endothelial cell dysfunction, interstitial cell differentiation, and pathological matrix remodeling. Our research seeks to reveal this mechanism using novel, unique to our laboratory tools, greatly facilitating the discovery and new clinical strategies for controlling early-detected valve disease with minimally invasive interventions.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130478262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A customer needs survey was distributed to students registered with Student Disability Services to determine aspects of the device. The device will include the eZ430-Chronos Development Tool (digital watch) which will control peripheral devices that will be set on the desk of the student.

The application of nanocarriers to conventional cancer treatment aims to address these problems by encapsulating chemotherapeutic drugs within polymer or lipid nanoparticles. These drug delivery nanoparticles, known as nanocarriers, work to increase the stability and circulation time of drugs and can be used to target specific areas. This project aims to fabricate nanocarriers for the delivery of chemotherapeutic drugs in order to address the current problems of chemotherapy.
