A Roadmap to Non-hematopoietic Stem Cell-Based Therapeutics: From the Bench to the Clinic is a resource that provides an overview of the principles of stem cell therapy, the promises and challenges of using stem cells for treating various clinical conditions, and future perspectives. The overall goal is to facilitate the translation of basic research on stem cells to clinical applications. The properties of stem cells from various sources are reviewed and the advantages and disadvantages of each for clinical use are discussed. Modifying stem cell properties through preconditioning strategies using physical, chemical, genetic, and molecular manipulation to improve cell survival, increase cell differentiation potential, enhance production of paracrine factors, and facilitate homing to the site of injury or disease upon transplantation are reviewed. Various routes of stem cell administration and dosing, and the duration of effects, are explored. Individual chapters are written by experts in the field and focus on the use of stem cells in treating various degenerative diseases, autoimmune diseases, wound healing, cardiovascular disease, spinal cord injury, oral and dental diseases, and skeletal disorders. Finally, experts in the regulatory arena discuss mechanisms used in different countries for approving the use of stem cells to treat diseases and many common issues that are typically encountered while seeking approval for this class of therapeutic agent.

Offers advanced students, as well as new researchers, an overview of the principles of stem cell therapy Discusses a wide array of pressing clinical issues with stem cell-based therapies so that new ideas in the laboratory can be efficiently translated to the clinic through better designed clinical trials Helps clarify current regulatory mechanisms so that the safe use of stem cells for treating a variety of diseases can move forward Fosters cross-disciplinary dialogue between research scientists and physicians to accelerate the safe implementation of efficacious cell therapies

This book covers the latest developments and advances in spray drying and describes how they impact the basic aspect of designing and operating spray dryers. This generic approach allows users to understand how different basic aspects of spray drying have advanced. Users will learn how to apply these advances in their own specific spray drying applications. This book also discusses the handling and control of spray dried products. Includes the latest techniques for use in the design and operation of spray drying operations Covers the basic operations of spray drying that can be applied to different applications of spray drying Discusses the handling and control of spray dried product qualities from a general approach, allowing readers to tailor these approaches to their own specific productsThis book is aimed at professionals, researchers, and academics working in the fields of food, chemical, pharmaceutical, and industrial engineering.

This comprehensive summary of the state of the art and the ideas behind the reaction engineering approach (REA) to drying processes is an ideal resource for researchers, academics and industry practitioners. Starting with the formulation, modelling and applications of the lumped-REA, it goes on to detail the use of the REA to describe local evaporation and condensation, and its coupling with equations of conservation of heat and mass transfer, called the spatial-REA, to model non-equilibrium multiphase drying. Finally, it summarises other established drying models, discussing their features, limitations and comparisons with the REA. Application examples featured throughout help fine-tune the models and implement them for process design and the evaluation of existing drying processes and product quality during drying. Further uses of the principles of REA are demonstrated, including computational fluid dynamics-based modelling, and further expanded to model other simultaneous heat and mass transfer processes.

Drying is by far the most useful large scale operation method of keeping solid foods safe for long periods of time, and is of fundamental importance in most sectors of food processing. Drying operations need to be precisely controlled and optimized in order to produce a good quality product that has the highest level of nutrient retention and flavor whilst maintaining microbial safety. This volume provides an up to date account of all the major drying technologies employed in the food industry and their underlying scientific principles and effects. Various equipment designs are classified and described. The impact of drying on food properties is covered, and the micro-structural changes caused by the process are examined, highlighting their usefulness in process analysis and food design. Key methods for assessing food properties of dried products are described, and pre-concentration and drying control strategies are reviewed. Thermal hazards and fire/explosion detection and prevention for dryers are discussed in a dedicated chapter. Where appropriate, sample calculations are included for engineers and technologists to follow. The book is directed at food scientists and technologists in industry and research, food engineers and drying equipment manufacturers.

Mostindustrialbiotechnologicalprocessesareoperatedempirically.Oneofthe major di?culties of applying advanced control theories is the highly nonlinear nature of the processes. This book examines approaches based on arti?cial intelligencemethods,inparticular,geneticalgorithmsandneuralnetworks,for monitoring, modelling and optimization of fed-batch fermentation processes. The main aim of a process control is to maximize the ?nal product with minimum development and production costs. This book is interdisciplinary in nature, combining topics from biotechn- ogy, arti?cial intelligence, system identi?cation, process monitoring, process modelling and optimal control. Both simulation and experimental validation are performed in this study to demonstrate the suitability and feasibility of proposed methodologies. An online biomass sensor is constructed using a - current neural network for predicting the biomass concentration online with only three measurements (dissolved oxygen, volume and feed rate). Results show that the proposed sensor is comparable or even superior to other sensors proposed in the literature that use more than three measurements. Biote- nological processes are modelled by cascading two recurrent neural networks. It is found that neural models are able to describe the processes with high accuracy. Optimization of the ?nal product is achieved using modi?ed genetic algorithms to determine optimal feed rate pro?les. Experimental results of the corresponding production yields demonstrate that genetic algorithms are powerful tools for optimization of highly nonlinear systems. Moreover, a c- bination of recurrentneural networks and genetic algorithms provides a useful and cost-e?ective methodology for optimizing biotechnological processes.
