The initial chapters provide a foundational overview of prebiotics and introduce readers to the concept of the gut-brain axis. It discusses bi-directional communication within the gut-brain axis and the impacts of gut dysbiosis on neurological health. Further chapters investigate the relationship between the gut-brain axis and autoimmune diseases and the role of probiotics in major neurodegenerative diseases such as Alzheimer's and Parkinson's, ALS and Huntington's disease, and conditions like MS, epilepsy, and seizures. It also examines the influence of prebiotics on mental health disorders such as anxiety and depression, and their impact on ischemic stroke via the gut-brain axis. The book further covers the role of probiotics in ROS and inflammation-mediated neurodegenerative diseases, and the correlation between gut microbiota, malnutrition, and neurological disorders. The book explores the signaling pathways within the gut-brain axis and their relationships with neurological disorders, the application of prebiotics as functional foods, and the therapeutic potential of postbiotics and psychobiotics. This book is intended for scientists and researchers in the fields of microbiology, neuroscience, and gastroenterology. ![]() Free Download Biotechnology for Fuels and Chemicals: Proceedings of the Nineteenth Symposium on Biotechnology for Fuels and Chemicals Held May 4-8. 1997, at Colorado Springs, Colorado By Michael R. Ladisch, Lynn Wright (auth.), Mark Finkelstein, Brian H. Davison (eds.) 1998 | 1015 Pages | ISBN: 1461272955 | PDF | 25 MB In Biotechnology for Fuels and Chemicals, based on the 19th Symposium, held in Colorado Springs, CO, May 4-8, 1997, leading researchers from academia, industry, and government present their new applications and cutting-edge research advances in the production of fuels and chemicals through biotechnology. The focus of the proceeding was on the utilization of renewable resources, particularly cellulosic biomass. Biotechnology for Fuels and Chemicals covers a wide range of technical topics. Among the high points are innovative pretreatment processes that can turn lignocellulosic materials into simple sugars, the development of exciting new biocatalysts and microbes, new reactor designs, and inventive conversion processes. Also discussed are a number of microbes and plants that have been genetically modified to perform novel bioconversions to produce enzymes and key chemical intermediates. The meeting clearly demonstrated that biotechnology and bioprocessing can make it possible to convert cellulosic biomass into fuels and chemicals in a commercially attractive fashion. ![]() Free Download Biotechnology for Fuels and Chemicals: Proceedings of the Eighteenth Symposium on Biotechnology for Fuels and Chemicals Held May 5-9, 1996, at Gatlinburg, Tennessee By Mark T. Holtzapple, Robert Torget (auth.), Brian H. Davison, Charles E. Wyman, Mark Finkelstein (eds.) 1997 | 898 Pages | ISBN: 1461274974 | PDF | 24 MB In Biotechnology for Fuels and Chemicals, based on the 18th Symposium, held in Oak Ridge, TN, May 5-9, 1996, leading researchers from academia, industry, and government present state-of-the-art research results and promising new concepts on the use of biotechnology to produce fuels and chemicals competitively. The contributions emphasize the utilization of renewable resources, but also include the bioconversion of fossil fuels and syngas, as well as the new area of conversions in nonaqueous environments. The Eighteenth Symposium on Biotechnology for Fuels and Chemicals covers the development of new biological agents (such as enzymes or microbes) to carry out targeted conversions, in addition to actual bioprocess development. Topics range from improvements in enzymes to fundamental insights into substrate-enzyme interactions and photosynthesis, and from conversions of substrates using biological agents to combinations of chemical engineering, biological sciences, and fermentation technology. Agricultural crops, such as corn and corn fiber, as well as woody biomass and lignocellulosic wastes, are investigated for use in process feedstocks, including pretreatment studies. Also treated are a variety of potential bioconversion products, including fumaric acid, succinic acid, methane, enzymes, glucuronic acid, and biodiesel fuel. The novel concepts, techniques, and research results reported in The Eighteenth Symposium on Biotechnology for Fuels and Chemicals are important contributions to the development of the new biological processes needed for the production of fuels and chemicals on a large scale, for the reduction of pollution, for solving waste disposal problems, and for helping remediate global climate change. ![]() Free Download Biotechnology and the Human Good By C. Ben Mitchell, Edmund D. Pellegrino, Jean Bethke Elshtain, John Frederic Kilner, Scott B. Rae 2007 | 225 Pages | ISBN: 1589011384 | PDF | 1 MB Some of humankind's greatest tools have been forged in the research laboratory. Who could argue that medical advances like antibiotics, blood transfusions, and pacemakers have not improved the quality of people's lives? But with each new technological breakthrough there comes an array of consequences, at once predicted and unpredictable, beneficial and hazardous. Outcry over recent developments in the reproductive and genetic sciences has revealed deep fissures in society's perception of biotechnical progress. Many are concerned that reckless technological development, driven by consumerist impulses and greedy entrepreneurialism, has the potential to radically shift the human condition - and not for the greater good. "Biotechnology and the Human Good" builds a case for a stewardship deeply rooted in Judeo-Christian theism to responsibly interpret and assess new technologies in a way that answers this concern. The authors jointly recognize humans not as autonomous beings but as ones accountable to each other, to the world they live in, and to God. They argue that to question and critique how fields like cybernetics, nanotechnology, and genetics might affect our future is not anti-science, anti-industry, or anti-progress, but rather a way to promote human flourishing, common sense, and good stewardship. A synthetic work drawing on the thought of a physician, ethicists, and a theologian, "Biotechnology and the Human Good" reminds us that although technology is a powerful and often awe-inspiring tool, it is what lies in the heart and soul of who wields this tool that truly makes the difference in our world. ![]() Free Download Biostatistical Methods and Applications in Health Research: A Case Study Approach English | 2025 | ISBN: 1032700971 | 335 pages | True PDF,EPUB | 11.48 MB Supported by real-world case studies, this essential textbook provides a detailed overview of the use of biostatistical tools and methods, enabling students and researchers to undertake their own research with confidence and understanding.
