Download or read book Endotoxins Structure Function and Recognition written by Xiaoyuan Wang and published by Springer Science & Business Media. This book was released on 2010-06-30 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endotoxins are potentially toxic compounds produced by Gram-negative bacteria including some pathogens. Unlike exotoxins, which are secreted in soluble form by live bacteria, endotoxins are comprised of structural components of bacteria. Endotoxins can cause a whole-body inflammatory state, sepsis, leading to low blood pressure, multiple organ dysfunction syndrome and death. This book brings together contributions from researchers in the forefront of these subjects. It is divided into two sections. The first deals with how endotoxins are synthesized and end up on the bacterial surface. The second discussed how endotoxins activate TLR4 and, in turn, how TLR4 generates the molecular signals leading to infectious and inflammatory diseases. The way endotoxins interact with the host cells is fundamental to understanding the mechanism of sepsis, and recent research on these aspects of endotoxins has served to illuminate previously undescribed functions of the innate immune system. This volume presents a description of endotoxins according to their genetic constitution, structure, function and mode of interaction with host cells.

Download or read book Endotoxin Detection and Control in Pharma Limulus and Mammalian Systems written by Kevin L. Williams and published by Springer. This book was released on 2019-07-24 with total page 865 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endotoxin detection and control is a dynamic area of applied science that touches a vast number of complex subjects. The intersection of test activities includes the use of an ancient blood system from an odd “living fossil” (Limulus). It is used to detect remnants of the most primitive and destructive forms of life (prokaryotes) as contaminants of complex modern systems (mammalian and Pharma). Recent challenges in the field include those associated with the application of traditional methods to new types of molecules and manufacturing processes. The advent of “at will” production of biologics in lieu of harvesting animal proteins has revolutionized the treatment of disease. While the fruits of the biotechnology revolution are widely acknowledged, the realization of the differences in the means of production and changes in the manner of control of potential impurities and contaminants in regard to the new versus the old are less widely appreciated. Endotoxin as an ancient, dynamic interface between lifeforms, provides a singular perspective from which to view the parallel development of ancient and modern organisms as well as the progress of man in deciphering the complexity of their interactions in his efforts to overcome disease.

Download or read book Biology and Conservation of Horseshoe Crabs written by John T. Tanacredi and published by Springer Science & Business Media. This book was released on 2009-06-04 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horseshoe crabs, those mysterious ancient mariners, lured me into the sea as a child along the beaches of New Jersey. Drawn to their shiny domed shells and spiked tails, I could not resist picking them up, turning them over and watching the wondrous mechanical movement of their glistening legs, articulating with one another as smoothly as the inner working of a clock. What was it like to be a horseshoe crab, I wondered? What did they eat? Did they always move around together? Why were some so large and others much smaller? How old were they, anyway? What must it feel like to live underwater? What else was out there, down there, in the cool, green depths that gave rise to such intriguing creatures? The only way to find out, I reasoned, would be to go into the ocean and see for myself, and so I did, and more than 60 years later, I still do.

Download or read book Septic Shock Methods and Protocols written by Thomas J. Evans and published by Springer Science & Business Media. This book was released on 2000 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Septic shock remains a serious medical condition with high mortality. Despite many advances in intensive care medicine and antibiotic devel- ment, this has not changed appreciably in the last 20 years. Frustratingly, over the same period of time, enormous advances have been made in understa- ing the underlying pathogenic mechanisms of this condition. This has resulted in the development of several novel therapies for septic shock, which, despite excellent theoretical grounds for their efficacy, have failed in altering mort- ity attributable to sepsis. The reasons for these failures are multiple, but it is clear that further research is required aimed at increasing our understanding of the basic pat- physiological processes that occur following infection. Research into septic shock draws upon a number of different disciplines, ranging from molecular and cellular biology to physiological measurements on whole animals. Septic Shock Methods and Protocols is an attempt to draw together into one volume a number of protocols that are of use in the investigation of the mechanisms of septic shock. I have divided the book into five sections. The first deals with endotoxin, the lipopolysaccharide component of the Gram-negative cell m- brane that can mimic many of the features of septic shock. Gram-positive organisms are found increasingly as causes of septic shock, and several - pects of toxins produced from these bacteria are considered in the second s- tion.

Download or read book Pathology of Septic Shock written by Ernst T. Rietschel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Severe sepsis and septic shock are the most serious compli cations of bacterial infections. Both gram-positive and gram negative bacteria can trigger these extreme inflammatory re sponses and, by so doing, cause substantial morbidity and mortality. In the United States alone, over 400 000 patients suffer from septicaemia each year, and approximately 100 000 of these patients die despite optimal intensive care and modern antimicrobial therapy. These dramatic figures have prompted intensive research to define the bacterial and host factors involved in the septic response. Scientists from many disciplines, including chem istry, physics, biology, medical microbiology, immunology, and pharmacology, have worked closely with clinicians to achieve rapid and profound progress. To translate this newly acquired knowledge into clinical practice, clinical trials have also been performed to evaluate numerous new therapeutic drugs. The disappointing results from these trials have underscored a major lesson, namely, that sepsis constitutes an extremely complex syndrome and that basic and clinical research must be greatly intensified in order to illuminate its molecular mechan isms. At this stage, the editors of the present volume of Current Topics in Microbiology and Immunology considered it would be rewarding to compile a volume summarizing our present basic and clinical knowledge on sepsis. Our particular gratitude extends to those international experts who have followed our invitation and elaborated on particular areas of the basic and clinical aspects of this field.
