Endothelial cells , the lining cells of blood vessels , are involved in many physiological and pathophysiological process, including haemostasis, vasoregulation, inflammation, angiogenesis, and the extravasation of fluids, macromolecules, hormones and leucocytes. This work was carried out to investigate the isolation, culture and characterization of human umbilical vein endothelial cells (HUVECs) in vitro by the help of Flow cytometry and Immunocytochemistry. Moreover, protocol was standardized to improve the cell yield and growth of these cells in culture. The endothelial cells were isolated by collagenase digestion and were seeded in tissue culture flasks using Dulbeccos modified Eagles medium (DMEM) –LG(Low Glucose) and M-200 media specific for ECGM (Endothelial Cell Growth Media ) containing LSGS( Low Serum Growth Supplement) and growth factor containing the (VEGF) and (bFGF) This study showed that HUVECS attached to to the gelatin coated tissue culture plates and become confluent after 3 days in vitro .HUVECs displayed cobblestone morphology at confluence with granular cytoplasm. HUVECs were positive for CD31- 3 % positivity, VE-Cadherin - 18.8% and vWF- 30.3%. Immunocytochemistry helped to anatomically a visualize the localization of endothelial cells marker. The cells produced from this technique grew well for extend periods and retained the normal characteristics of primary HUVECs, making them invaluable tools for researchers.

Chounta Talk @HCII: Linking Dialogue with Student Modeling to Create an Enhan...Irene-Angelica Chounta
The learning process and its outcomes depend greatly on the social interaction between teachers and students and, in particular, on the proficient and focused use of language through written text or discussions. Our overarching goal in this project is to better understand how to make automated tutorial dialogues effective and adaptive to student characteristics, such as prior knowledge. The specific goal of our current project is to develop an adaptive, natural-language tutoring system, driven by a student model, which can effectively carry out reflective conversations with students after they solve physics problems. Towards this end, we continue our work in identifying linguistic features of tutoring that predict learning gains, and extend it by characterizing the “level of support” to provide to students based on their current level of understanding particular physics concepts and principles, as dynamically captured by the student model. In this talk, I will describe the features of dialogic discourse underlying “level of support” that we have identified through the analysis of human-to-human tutorial dialogues as well as the construction and application of a coding scheme for the characterization of the “level of support”. I will present initial teacher feedback on dialogues that apply these features to coach students at different levels. I will also discuss how this line of research affects the authoring of tutorial dialogues used by an intelligent tutoring system for students who exhibit different levels of understanding.
Made this with a couple of my friends in 2015. It was to be submitted by Prakruti Kodali (ISB '16) for the Matrix Million Dollar B-Plan Elevator Pitch.

Traditional vs. SoC FPGA Design Flow A Video Pipeline Case StudyAltera Corporation
This presentation compares the impact of traditional FPGA engineering design flow to one employed with an SoC FPGA. The two approaches will be contrasted in terms of their impacts on system architecture design, debugging, risk mitigation, system integration, bring-up, feature enhancements, design obsolescence, and engineering effort. A case study is presented that explores these impacts within a video pipeline development effort.
