Reviews in Pharmaceutical and Biomedical Analysis contains coverage and review of new trends and applications in all areas of pharmaceutical, biomedical and analytical chemistry. Authors have contributed review articles according to their expertise on various relevant topics. The book's aim is to cover important instrumental analytical methods that are applied to the analysis of compounds with pharmaceutical and biomedical interest, including liquid and gas chromatography, electrophoresis & related techniques, mass spectrometry, hyphenated techniques, automated analytical techniques, spectrometry, luminescence, electroanalysis etc. Since the analysis of pharmaceuticals in a variety of matrices (formulations, biological material, environmental samples) is and will continue to be a "hot" topic, such a review book will be of interest to a very broad spectrum of scientists involved in chemistry and medicine.

Understanding the dispersion and the deposition of inertial particles convected by turbulent flows is a domain of research of considerable industrial interest. Inertial particle transport and dispersion are encountered in a wide range of flow configurations, whether they are of industrial or environmental character. Conventional models for turbulent dispersed flows do not appear capable of meeting the growing needs of chemical, mechanical and petroleum industries in this regard and physical environment testing is prohibitive. Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) have become powerful tools for the investigation of particle-laden turbulent flows with the help of advances in computing resources. The hybrid Eulerian-Lagrangian approach plays a key role in predicting inertial particle dispersion and deposition. This ebook explains the use of stochastic tools to enhance the accuracy of the Eulerian-Lagrangian large eddy simulation of particle-laden turbulent flows of practical interest. The book should be a useful resource for chemical, mechanical, petroleum and environmental engineering postgraduates and researchers interested in applying tractable yet powerful numerical tools to solve problems involving multiphase flows.

Drug discovery is still a process which involves screening of a large number of chemical compounds against a defined biological target. However, this approach is now being gradually replaced by more rational and knowledge-based approaches, such as in sillico screening and target based drug development. Increase in the cost of development of NME (New Molecular Entities) and productivity crises in pharmaceutical industry are catalyzing this change. Spectacular advances in the field of use of NMR spectroscopy in drug discovery and development have been triggered by a greater understanding of the disease process at the molecular level. While NMR is generally valued as an important tool for structure determination and more recently as a non-invasive diagnostic technique, its potential in drug discovery is based on its capacity to map molecular interactions at the atomic level. Chemical shifts, cross relaxation, and exchange of protons are among the NMR parameters which are highly sensitive to the exact molecular environments , and therefore yield information about how a small molecule (candidate compound) binds to a target protein (receptor) or to other macromolecules. These NMR parameters are also used to exactly map the part of the macromolecular target to which the ligand is bound. As a result, NMR is now extensively used as an efficient tool in the drug (ligand) discovery and optimization process or for the assessment of target drug ability. Recent advances in NMR hardware and methodology have provided a fresh impetus in the area of pharmaceutical innovation and productivity. This book is aimed to present recent cutting edge knowledge, practices and experiences in this important field. The book comprises seven scholarly written articles . Mailavaram and Devarakonda in their introductory review skillfully summarize the broad approaches of NMR-based drug discovery . Park and Kim focus on the use of NMR spectroscopic techniques in the study of drug delivery, drug release and other pharmaceutic parameters. Roberto and Marina provide a chronological account of fragment-based drug discovery by using NMR-based screening methods. Specific utilization of NMR-based techniques in the discovery and development of anticancer drugs is reviewed by Solomon and Lee. Ramalho et al. review another fascinating application of NMR in understanding the behavior and radio sensitizing properties of bioreductive drugs. Zoppetti comprehensively reviews the application of NMR spectroscopy in the study of host-guest cyclodextrin complexes, particularly their use as drug delivery vehicles. A concise review is contributed by Nhat and Hong on recent advances in the field of application of NMR in structure-activity relationship study of nanostructure drugs. These contributions of outstanding group of experts make this a very useful treatise of highly readable articles. Our felicitations and gratitude goes to them. The book will hopefully fulfill an important need of the scientific community by providing comprehensive reviews on cutting edge topics written by leading experts in the field. We extend our warmest thanks to the staff of Bentham Science Publishers, particularly, to Mr. Mahmood Alam (Director), Ms. Taqdees Malik (Editorial Assistant) and Ms. Sadaf Idrees Khan (Composer) for undertaking the important task of closely coordinating with the contributors and preparing the content lists, index, etc.

Adulteration refers to the practice of altering food or pharmaceutical content to reduce production costs. Factors affecting this practice include market forces such as easy availability of food adulterants, bargaining power of consumers and large demand and supply gaps which incentivize such practices. Technological advancements in chemical analysis now help us to identify adulterated food and drugs more easily. Adulteration Analysis of Some Foods and Drugs is a sourcebook describing analytical methodologies for the determination of adulterants in different food items (milk, honey, juice) and drugs (dietary supplements, sildenafil and specific plant extracts). Additional chapters give guidelines for analyzing a food or drug sample. This book is suitable for researchers working in the field of analytical chemistry for the determination of adulterants. The concise and organized presentation of the contents also serves to enhance the level of knowledge of students undertaking food and drug safety / quality control training courses.
