Debra also has a MBA a MS and a patent for sensor development. Raina Khatri is a doctoral student in the Mallinson Institute for Science Education at Western Michigan University. Her research focus is understanding how education developers in STEM can promote sustained adoption of their innovations. Courtney Stanford is a postdoctoral researcher in the Department of Chemistry at Virginia Commonwealth University. Her current research focuses on the identification development and assessment of process skills (also known as professional skills) in active learning undergraduate STEM classrooms.

Scholarly studies and national reports document failure of current efforts to achieve broad, sustained adoption of research-based instructional practices, despite compelling bodies of evidence supporting efficacy of many of these practices. The authors of this paper argue that many change agents who are working to promote systemic adoption of these teaching practices use approaches that are characterized by what the authors call the "dissemination paradigm." A dissemination paradigm characterizes patterns of these current, failing efforts. Change agents, working within the dissemination paradigm, try to convince adopters that their innovations can help their students. Efforts within the dissemination paradigm have not led, and are unlikely to lead, to systemic adoption. The authors offer the "propagation paradigm" as an alternative with the potential to produce improved results. Change agents, working within the propagation paradigm, engage with adopters early and often to understand their instructional systems and interactively develop a strong product adaptable to specific contexts.

The roles of porosity, surface area, and catalyst acidity influenced pyrolysis product distribution. This research aims to improve the yield of pyrolysis oil produced through the pyrolysis of palm fronds with the assistance of beta zeolite (BEA) catalysts compared to those without catalysts. The effects of temperature during thermal pyrolysis, the SiO2/Al2O3 ratio of the BEA zeolite extrudate, and catalyst-to-feed (C/F) ratio during in situ catalytic cracking of palm fronds on the product distribution have been studied using a fixed-bed reactor by which the catalyst bed was put on top of the biomass bed. Thermal pyrolysis of palm fronds at 500 °C produced a higher yield of pyrolysis oil dominated by oxygenated aromatic compounds, whereas in-situ catalytic pyrolysis at a C/F ratio of 0.31 g/g and temperature of 500 °C increased the pyrolysis oil yield from 64.8% to 68.6% and 68.1%, respectively. The BEA-1 and BEA-2 increased the hemicellulose decomposition process by producing pyran and increasing cyclic ketone, acid, and gas yield. The catalytic cracking of the vapor of pyrolysis oil over BEA-1 was more active than BEA-2 because of higher acidity and deposited carbon on the catalyst. Therefore, using more acidic zeolite extrudate could improve pyrolysis oil yield.

Dendritic cell (DC) maturation and antigen presentation are key factors for successful vaccine-based cancer immunotherapy. This study developed manganese-based layered double hydroxide (Mn-LDH) nanoparticles as a self-adjuvanted vaccine carrier that not only promoted DC maturation through synergistically depleting endogenous glutathione (GSH) and activating STING signaling pathway, but also facilitated the delivery of model antigen ovalbumin (OVA) into lymph nodes and subsequent antigen presentation in DCs. Significant therapeutic-prophylactic efficacy of the OVA-loaded Mn-LDH (OVA/Mn-LDH) nanovaccine was determined by the tumor growth inhibition in the mice bearing B16-OVA tumor. Our results showed that the OVA/Mn-LDH nanoparticles could be a potent delivery system for cancer vaccine development without the need of adjuvant. Therefore, the combination of GSH exhaustion and STING pathway activation might be an advisable approach for promoting DC maturation and antigen presentation, finally improving cancer vaccine efficacy.

The Broad Institute-Six Years Later

引用

CHEMISTRY & BIOLOGY 2010年第4期17卷 311-312页

作者： McCarthy, Alice Main Text “In June 2003 the scientific and medical communities at MIT Harvard University and its affiliated hospitals and the Whitehead Institute banded together as collaborating partners to form the Eli and Edythe L. Broad Institute based in Cambridge MA. The Broad Institute established with initial funding from a $100 million philanthropic donation from the Los Angeles-based Broad family was primarily viewed as a marriage between the Whitehead Institute's Center for Genome Research (WICGR) and the Harvard Institute of Chemistry and Cell Biology (ICCB). Eli Broad founder and chairman of AIG SunAmerica Inc. explained “the purpose of the Broad Institute is to create a new type of research institute to build on the accomplishments of the human genome project and to move to clinical applications to both prevent and cure diseases.” Every Thursday morning we meet with perhaps 20 faculty members and 100 other researchers to discuss what we're all doing and should be doing next. -David Altschuler This paragraph was written five years ago when the Broad Institute was in its very earliest days as a life science research community (McCarthy 2005). Since that time “the Broad” as it's known has kept true to Eli Broad's vision having attracted a talented group of researchers faculty trainees and professional staff. This 1600 person research community known internally as “Broadies” includes faculty staff and students from throughout the MIT and Harvard biomedical research communities and beyond with collaborations spanning over a hundred private and public institutions in more than 40 countries worldwide. “What is special about the Broad is that we have people from Harvard MIT and the Harvard hospitals come together and work on problems of shared interest that could not be solved in their own individuals labs” explains David Altshuler M.D. Ph.D. Deputy Director and one of the Broad's six core faculty members. “These problems require expertise beyond any one principal investigator and in
