EXTRACTION AND BIOCHEMICAL CHARACTERIZATION OF ALLIGATOR MISSISSIPPIENSIS GLYCOSAMINOGLYCANS AND AN EX-VIVO MURINE PILOT STUDY TO TEST THEIR POTENTIAL EFFECT ON A SELECTED PANEL OF GENES ASSOCIATED WITH CYSTIC FIBROSIS A Dissertation Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The School of Nutrition and Food Science by Jose Daniel Estrada Andino B.S., Escuela Agrícola Panamericana Zamorano, 2007 M.S., Louisiana State University, 2011 August 2016 This work is dedicated to my amazing wife Monika and all of my family in Honduras, Germany and Poland. ii ACKNOWLEDGEMENTS I want to express my deepest gratitude to everyone who played a role in the completion of this work. First of all I thank God for the daily assurance of purpose in my life and for all the people whom he used for my academic, professional, personal and academic growth during the past few years. To Dr. Jack Losso, thank you so much for being an admirable person, great friend, and an inspiring and always supportive mentor. Thank you for trusting in me to conduct such a relevant project for the Louisiana alligator industry and for simultaneously allowing me to have a well- rounded experience through my involvement in national new product development competitions, IFT competitions and an amazing food industry internship. Under your mentorship I have become a better person and professional. To my committee members, Dr. Joan King, Dr. Roger Laine, Dr. Grover Waldrop, Dr. Yogesh Saini, Mr. Mark Shirley and Dr. Erin Casey, thank you for your valuable time and guidance. Special thanks to Mr. Mark Shirley and Dr. Yogesh Saini for their hands-on support and training in the field and laboratory, respectively. To all my collaborators in the experiments carried out for this dissertation, Mr. Cristian Macoto, Dr. Marvin Moncada, Dr. Luis Espinoza and Ms. Jeimy Menjivar in the processing of alligator by-products, Dr. Richard Cooper for allowing me to use his molecular biology laboratory iii and equipment, Dr. George Stanley for his FT-IR training and Dr. Kenneth Smith at Thermo Fisher Scientific for his kind support with FT-IR data collection. I would also like to thank all my labmates and friends at the School of Nutrition and Food Science and around the LSU campus for all their support and encouragement expressed in many different ways. Especially, Srikanth, Namrata, Kennet, Ryan, Reynaldo, Alejandro and Damir. To my Baton Rouge parents Mark and Alicia, your friendship and care have made this town feel like home. To my SBRPC family, thank you for supporting me in prayer and also in many practical ways even before I arrived here. Finally, to my wife Monika and my family in Honduras, Poland and Germany. Thank you for supporting my goals and always believing in my potential. I would not have made it so far without all of you. Monika, your willingness to move from Germany to Baton Rouge gave me the gift of an outstanding PhD student experience next to you. iv TABLE OF CONTENTS ACKNOWLEDGEMENTS ........................................................................................................... iii LIST OF TABLES ........................................................................................................................ vii LIST OF FIGURES ..................................................................................................................... viii ABBREVIATIONS INDEX ........................................................................................................... x ABSTRACT ................................................................................................................................. xiv CHAPTER 1 INTRODUCTION .................................................................................................... 1 CHAPTER 2 LITERATURE REVIEW ......................................................................................... 5 2.1.

Ayurvedic College, Guwahati, Assam, India. ABSTRACT Burn injury has been associated with the evolution of human civilization since time immemorial. Burn injuries has always been faced by human in different era with change of mode injury from past to present. Unlike other diseases the basics of burn injury remains more or less same. The basic concepts and principles of management of burn injury is described in Ayurveda are very much relevant and useful in this era of modern surgery. Sushrut Samhita, the treasure of surgical knowledge of ancient Indian civilization, is a rich source of information regarding burn injury, assessment and management. Most of the other scholars of Ayurveda follow the basic concept of Sushrut Samhita. All the Brihatrayee (three greater treatises) and Laghu trayee (three lesser treatises) and other relevant textbooks of Ayurveda studied to search the different data regarding Dagdha vrana (burn injury), etiological description, gradation, different principles of treatment and available dressing material. The collected data evaluated scientifically to make it usable in the modern era of surgery. The result shows that although there is change in mode of burn injury found in modern era, the basic principles of etiology, classification, management and use of dressing material are almost the same as standard burn wound management of contemporary medical science.

  • A Concise Review on Scarless Wound Healing
    Aswany U R et al /J. Pharm. Sci. & Res. Vol. 13(1), 2021, 1-7 A Concise Review on Scarless Wound Healing Aswany U R*, Anzal N Ezhuthachan College of Pharmaceutical Sciences Marayamuttom, Neyyattinkara, Thiruvananthapuram-695124 Abstract: This review is focused on the scarless wound healing by using wound healing products, which typically aim either to reduce scarring , decrease the time of wound healing or to reduce inflammation.This review highlights basics of wound healing, strategies to reduce scarring ,role of silver nanoparticles in wound healing, the application of regenerative medicine in scarless wound healing. Pharmaceutical products including both traditional plant-based materials and proteins have been found as effective wound cures to reduce or eliminate scars. Keywords: Epithelialization, Fibroblasts, Scar, Wound healing INTRODUCTION Scar formation is a prevalent, undesirable consequence of In adult (postnatal) mammalian organisms, injury to most wound healing events, along with significant cutaneous tissue with disruption of normal skin psychological, emotional, and social problems. It is always architecture is repaired by means of an inflammatory and desirable but difficult to develop wound treatment that fibrotic response that leads to accumulation of scar. allows prompt healing and less scarring, particularly in Although scar formation allows for the rapid sealing of an adult tissues. Accordingly, there have been considerable injured area, it can frequently prove the source of research and development efforts to not only accelerate the persistent pathology in the organism.
