Nelson and published by . This book was released on 1988 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resonance Raman Spectra have been obtained for a variety of chromobacteria using low power 488 nm excitation. Spectra are simple, of high quality, and useful for identification purposes at the species level. Raman microprobe studies show conclusively that spectra can be obtained from single cells in pure cultures or in mixed cultures without need for separation. Extensions of the study have been made to representative colorless gram-negative and gram-positive bacteria. Spora other than bacteria have been studied as well. Pollen, mold spores, bacterial spores, algae and viruses all give spectra but only viruses and bacterial spores appear to give intense UV Resonance Raman spectra. The primary fluorescence of bacteria has been studied in detail to determined its potential in rapid detection. We have determined fluorescence for S. epidermidis, P. fluorescens, E. cloacae, E. coli and B. subtilis. Fluorescence contributions have been assigned in part to tryptophan, pteridines, related flavins and pyridine coenzymes.
Download or read book Infectious Diseases written by Lester M Shulman and published by Springer Nature. This book was released on 2023-02-07 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on Infectious Diseases in an Encyclopedia of Sustainability Science and Technology (ESST) addresses the needs of health care providers and policy makers as well as scientists and engineers. Most of chapters in this volume deal with infectious diseases that directly affect humans, including the detailed characterization of specific pathogens, how they reproduce, how they are transmitted, and the means available to control, eliminate, or eradicate them. In this revised and updated second edition, the number of human infectious diseases covered has been significantly expanded. Other new chapters deal with current leading edge technologies for the diagnosis of pathogens; surveillance including environmental and syndromic surveillance for pathogens; requirements for quality assurance, quality control and the need for biological standards and controls to sustain high quality diagnosis and surveillance; the use of big data for personalized medicine; modeling infectious diseases; zoonotic and vector borne diseases; disease prevention with antibiotics, antivirals and vaccines; and factors that affect ecological balances leading to emergence of new diseases such as climate change and deforestation. Finally, infectious diseases that affect livestock and culture of plants for food, comfort and beauty are also addressed, since we must also consider them when discussing sustainability of humans in our ecosystem.

Available in PDF, EPUB and Kindle. Book excerpt: Infectious Diseases: Selected Entries from the Encyclopedia of Sustainability Science and Technology presents authoritative, peer-reviewed contributions from leading experts on a wide range of major infectious diseases of global importance. Infectious diseases account for more than 17 million deaths each year worldwide. While modern medicine and technology have diminished the threat of many of these pathogens in high-income countries, the ever present threats of re-emerging infections, population mobility, natural disasters, and pathogen genetic variability are but some of the reasons for the dynamic threat of this broad category of risks to human health. An indispensable resource for students and scientists, the volume also covers some of the new technologies currently under development for infectious disease prevention, treatment, and eradication. The greater part of the infectious disease burden remains in the tropics, where low and middle-income countries lack the resources, infrastructure, and health systems to mount or sustain control efforts. Many contributions describe the efforts of the scientific research community and international donor agencies to achieve the integrated goals of vigilant surveillance, improved and cost-effective diagnostics, and treatment for sustainable disease control.

Available in PDF, EPUB and Kindle. Book excerpt: Since the inelastic scattering of light was predicted nearly 100 years ago, Raman spectroscopy has become a mainstay of characterization techniques, with applications in a vast array of fields from chemistry to materials science and nanotechnology, from forensics to geology and art. More recently, it has found usage in the life sciences, and this book hereby outlines the state-of-the-art advances in applications of Raman spectroscopy to human health and biomedicine. It covers a wide range of human health science including medicine (especially cancer), physiology, biological molecules, pharmaceutical science, cells, viruses, microorganisms, and food science. Another highlight is that it describes recent progress on various Raman techniques such as surface-enhanced Raman scattering, tip-enhanced Raman scattering, non-linear Raman spectroscopy, Raman microscopy, and Raman imaging. Novel spectral analysis methods such as chemometrics are also prominently discussed.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Raman spectroscopy utilizing a Raman microscope can be used to study various biological samples. Based on approaches using difference spectroscopy, rapid mix -rapid freeze, and freeze drying of enzyme-inhibitor mixtures and bacterial cells, we developed several novel protocols. These enabled us to identify the enzymatic reaction intermediates and inhibition pathways in aqueous solutions and inside cells. The recent results complement the reactions of various ß-lactamases with different inhibitors in single crystals, elucidated in the Carey laboratory for more than a decade. Taken together, the in vitro results allow us to characterize the populations and reactions of drug molecules inside bacterial cells. A Raman microscope was used with a combination of rapid mix - rapid freeze, and freeze drying to study the reaction of SHV-1 ß-lactamase with tazobactam, and trap early intermediates in a dilute aqueous solution milliseconds after mixing. To extend the comparison of solution and crystal reactions, we used another clinically important ß-lactamase enzyme, CTX-M-9 reacting with clavulanic acid, sulbactam, or tazobactam. We identified an infrequent path of inhibition for this enzyme when reacted with each of the three inhibitors. In solution and in single crystals, each formed an irreversible ß-alkoxyacrylate species. Using Raman microscopy to characterize freeze-dried bacterial cells, we studied the populations and reactions of two different classes of inhibitors inside the cells. With clavulanic acid and tazobactam, which are known inhibitors of SHV-1 ß-lactamase, we identified the formation of enamine intermediates inside cells expressing SHV-1. The population of free clavulanic acid was measured inside each bacterial cell when the cells were not expressing the target enzyme. For the second class of compounds we measured the population of dihyofolate reductase (DHFR) inhibitors, (the propargyl-based UCP 1038 and UCP 1089) inside Gram-negative and Gram-positive bacteria after different times of exposure to the inhibitors. Single crystal studies indicate that the protonation of the diaminopyrimidine ring of the inhibitors occurs upon binding to DHFR. Identical spectral changes occur in bacterial cells, suggesting that the protonation is occurring for inhibitors upon binding to the intra-cellular targets.
