Available in PDF, EPUB and Kindle. Book excerpt: This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.
Download or read book Nitric Oxide written by Louis J. Ignarro and published by Academic Press. This book was released on 2000-09-13 with total page 1023 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitric oxide (NO) is a gas that transmits signals in an organism. Signal transmission by a gas that is produced by one cell and which penetrates through membranes and regulates the function of another cell represents an entirely new principle for signaling in biological systems. NO is a signal molecule of key importance for the cardiovascular system acting as a regulator of blood pressure and as a gatekeeper of blood flow to different organs. NO also exerts a series of other functions, such as acting a signal molecule in the nervous system and as a weapon against infections. NO is present in most living creatures and made by many different types of cells. NO research has led to new treatments for treating heart as well as lung diseases, shock, and impotence. Scientists are currently testing whether NO can be used to stop the growth of cancerous tumors, since the gas can induce programmed cell death, apoptosis. This book is the first comprehensive text on nitric oxide to cover all aspects--basic biology, chemistry, pathobiology, effects on various disease states, and therapeutic implications. Edited by Nobel Laureate Louis J. Ignarro, editor of the Academic Press journal, Nitric Oxide Authored by world experts on nitric oxide Includes an overview of basic principles of biology and chemical biology Covers principles of pathobiology, including the nervous system, cardiovascular function, pulmonary function, and immune defense

Book excerpt: Radicals for Life: the Various Forms of Nitric Oxide provides an up-to-date overview of the role of nitrosocompounds and nitrosyl-iron complexes in physiology. Nitrosocompounds can be considered as stabilised forms of nitric oxide, one of the most important regulatory molecules in physiology today. Many nitrosocompounds share some of the physiological functions of nitric oxide, and may be formed inside living organisms. This is the first book to be published that is dedicated to the role of such nitrosocompounds in physiology, with particular emphasis on the nitrosocompounds that are endogenously formed in higher organisms and humans. Points of discussion include: physical and chemical properties of the compounds, the main chemical pathways in vivo, as well as the physiological effects that have been recognised to date. Each of the nineteen chapters is written by distinguished specialists in the field, well known for their original and important contributions to the subject. Also included are results from a wide range of studies in vitro, in cell cultures, animal models and human volunteers. Examples of alternative forms of nitric oxide, with special emphasis on their protective role against widespread human diseases like atherosclerosis, Alzheimer's disease, diabetes, sexual dysfunction, and renal insufficiency to stroke and ischemia are also included. First monograph to consider and provide an overview of endogenous nitrosocompounds and nitrosyl-iron complexes Extensive bibliographic references, written by specialists of human physiology Providing high scientific quality with a focus on implications for human diseases

Abstract: Abstract of thesis entitled BIOMIMETIC REACTIONS OF NITRIC OXIDE SYNTHASE - STUDY OF THE REACTIONS OF N-SUBSTITUTED-N-HYDROXYGUANIDINES WITH METALLOPORPHYRIN AND NON-HEME COMPLEXES Submitted by Chu Tsun Tung For the Degree of Doctor of Philosophy at The University of Hong Kong in April 2007 Nitric oxide (NO) is one of the most important biological messengers. The generation of NO in animals is carried out by nitric oxide synthase (NOS), an enzyme which catalyzes the two-step. The first step is a 2-electron oxidation of L- Arg to N-hydroxyarginine (NHA), which similar to cytochrome P450 monoxidase type reaction. The second step is a three 3-electron oxidation of N-hydroxyarginine to NO and citrulline. Continuous studies of unusual aerobic oxidation of NHA catalyzed by NOS lead to several proposed mechanisms for the reaction. One of the proposed mechanisms features the ligation of NHA to Fe(III)-heme followed by Fe- O bond homolysis to generate Fe(II)-heme and iminoxy radical. This mechanism was supported by a chemical model system that employs fluorenone oxime and [Fe(OH)(Por)]. Inspired by this model, some N-hydroxyguanidines (NHGs), instead of an oxime, were used as substrate in our studies because N-hydroxyguanidine is the characteristic function group of NHA. All these NHGs were found ligating to [Fe(TMP)], and an X-ray crystal structure of NHG ligated [Fe(TMP)] has been determined, which supports that NHGs can ligate to iron via oxygen. Mechanistic studies of the aerobic oxidation of NHGs support that the NHG oxidation is initiated by O -assisted Fe-O bond homolysis. Guanidine and urea were thought to be the reaction products of iminoxy radical with other iminoxy radical or NHGs. HNO was thought to be one of the nitrogen oxide products, which was supported by the detection of N O in the reaction headspace gas. A modified mechanism of NOS catalyzed oxidation of NHA to citrulline and NO was proposed according to the findings of our studies and other new mechanistic findings about NOS reaction. The aerobic oxidations of some trisubstituted NHGs catalyzed by [Fe(OH)(TMP)] generated 3-amino-1,2,4-oxadiazoles as products. Some non-heme iron complexes and metalloporphyrins were tested for the catalytic properties towards the oxidative cyclization of NHGs. Complexes [nBu N][Fe(L)(Cl) ] (L = 4 2 bispyridylamide type ligands) were found to be good catalysts, which gave the corresponding oxadiazole in 80% yield within 1.5 hours from N, N-dimethyl-N'- benzyl-N"-hydroxyguanidine (DMBH). Mechanistic studies for the oxidative cyclization of NHGs catalyzed by the [nBu N][Fe(L)(Cl)] complexes were 4 2 performed and a mechanism for the reaction was proposed.

This book was released on 2013-11-11 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation of atmospheric nitrogen gas by denitrifying bacteria may represent a significant nutrient sink in natural ecosystems. The rate of denitrification has often been difficult to measure in situ, however, and new methodologies should stimulate research on distribution of activity in space and time. The load of fertilizer nitrogen in modem agriculture has led to increasing nutrient reservoirs in recipient subsoils, aquifers, inland waters and coastal seas. By its conversion of nitrate to atmospheric nitrogen, bacterial denitrification is the only biological process to potentially reduce the impact of increasing nutrient loadings by fertilizer nitrogen in the environment. As part of a scientific program set up by the Danish Ministry of Environment to study environment cycling of nitrogen, phosphorous and organic matter (NPO program) in the light of agricultural, domestic and industrial activities, a symposium on DENITRIFICATION IN SOIL AND SEDIMENT was held at the University of Aarhus, Denmark from 6-9 June 19i\9. On the basis of lectures given at the symposium, this book contains a number of invited contributions on the regulation of denitrification activity (control of enzyme synthesis and activity) and measurement of in situ rates of denitrification in terrestrial and aquatic environments (control factors, diel and seasonal variations, etc). Emphasis has been placed on including the recent improvements in methodologies and current understanding of process regulation, however the book also contains examples of integrated research on the significance of denitrification in environmental nutrient cycling.
