This very provocative book takes the reader on a “think-out-of-the-box” journey through the development of a treatment regimen for multiple myeloma called “dtZ”. It is a firsthand account of how more than 50 patients with myeloma were given a non-toxic, precisely-targeted, anti-cancer treatment that was specifically adapted to their individual cancers. These Individualized Anti-Cancer Targeted Therapies (smart bombs) have produced amongst the best responses as well as survival rates for myeloma. Accordingly, the author argues that some patients might even have been “cured” of their cancers.The concepts and logic behind “dtZ” are carefully presented in simple language so that both doctors and patients can easily understand them. Numerous tables and figures are provided, together with clear and simple explanations. This book is a valuable resource for all patients with myeloma who want to get the most out of their treatment by individualizing treatment to suit their needs, particularly for patients who have just been diagnosed with myeloma and who are taking that very important first step in their treatment. It is also a useful guide for doctors, nurses and researchers who treat and/or study myeloma.

Security, monitoring, and tuning techniques are also covered in this volume. All solutions are written with best practices and comes with complete to-the-point description and source code. You know the basics of the SQL query language, yet you feel you aren't taking full advantage of SQL's expressive power. You'd like to learn how to do more work with SQL inside the database before pushing data across the network to your applications. Let's face it, SQL is a deceptively simple language to learn, and many database developers never go far beyond the simple statement: SELECT columns FROM table WHERE conditions. But there is so much more you can do with the language. In the SQL Server - Tips and Tricks, experienced SQL developer Priyanka Agarwal shares her favorite SQL techniques and tricks to take your SQL skills to the next level. As you develop these skills, you will use either Microsoft SQL server to execute SQL statements. Everyone reading this book can jump right in with writing SQL statements in MS SQL Server with great ease. It's easy to find basic SQL syntax and keyword information online. What's hard to find is challenging, well-designed, real-world problems—the type of problems that come up all the time when you're dealing with data. Learning how to solve these problems will give you the skill and confidence to step up in your career. With SQL Server - Tips and Tricks, you can get that level of experience by solving sets of targeted problems. These aren't just problems designed to give an example of specific syntax. These are the most common problems you encounter when you deal with data. You will get real world practice, with real world data. I'll teach you how to "think" in SQL, how to analyze data problems, figure out the fundamentals, and work towards a solution that you can be proud of. It contains challenging problems, which develop your ability to write high quality SQL code. It has data analysis and reporting oriented challenges that are designed to step you through introductory, intermediate and advanced SQL Select statements, with a learn-by-doing technique. Most textbooks and courses have some practice problems. But most often, they're used just to illustrate a particular syntax. There's no filtering on what's most useful, and what the most common issues are. What you'll get with SQL Practice Problems is the problems that illustrate some the most common challenges you'll run into with data, and the best, most useful techniques to solve them.
