An accurate, inexpensive, and noninvasive method for the early diagnosis of cancer has been something of a holy grail among cancer researchers, but until recently a method meeting all three criteria has been elusive. Nucleic acids were first discovered in circulation in 1948, but it was not until the 1960s and 70s that patients with autoimmune disease and cancer were discovered to have higher levels of circulating DNA than were detected in in healthy persons. The focus in this volume is on three major applications of the circulating nucleic acids detection method: cancer, fetal medicine, and diseases such as diabetes, stroke, and myocardial infarction. In addition, there are reports on the biology and origins of circulating DNA and RNA and on improved methods for the detection of nucleic acids in plasma and serum. The circulating DNA found in cancer patients has many characteristics in common with their tumors, which made it an attractive candidate for use in the diagnosis and management of patients with malignancies. This method can also be applied to the assessment of the sublinical tumor burden in cancer patients, thus reducing the risk of unnecessary chemotherapy. Detection of nucleic acids circulating in maternal serum means that fetal diagnosis may be possible without resorting to the more dangerous and invasive methods now used (e.g., amniotic fluid and chorionic villus sampling). Detection of problems in the pregnancy such as preeclampsia and intrauterine growth retardation may also become possible through maternal blood samples. In diabetic patients, circulating nucleic acids can be used for the early detection of developments such as retinopathy. The benefits of using circulating nucleic acids in the diagnosis and management of cancer and chronic disease will be realized through earlier detection by means of this less expensive and less invasive testing technique and through its potential for closer monitoring of the disease.

DNA and RNA fractions have been isolated from whole blood, serum, plasma, the surface of blood cells, and urine from both healthy persons and patients. Specific fragments have been identified as being related to particular disorders, for example, diabetes, cancer, myocardial infarction, and stroke. The ability to isolate these fractions and assess their relationship to specific diseases makes early noninvasive diagnosis possible. This volume reports on the most recent progress in this field, including chapters on developing protocols for nucleic acid extraction, determining the origin of the circulating nucleic acids, the capacity of these nucleic acids to enter cells and exhibit biological activity, isolating and testing fetal cells from maternal blood, and discussing the clinical implications of these discoveries and developing the techniques that will bring them into clinical application.

This book investigates how, alongside Beatrice Webb’s ground-breaking pre-World War One anti-poverty campaigns, George Bernard Shaw helped launch the public debate about the relationship between equality, redistribution and democracy in a developed economy.The ten years following his great 1905 play on poverty Major Barbara present a puzzle to Shaw scholars, who have hitherto failed to appreciate both the centrality of the idea of equality in major plays like Getting Married, Misalliance, and Pygmalion, and to understand that his major political work, 1928’s The Intelligent Woman’s Guide to Socialism and Capitalism had its roots in this period before the Great War. As both the era’s leading dramatist and leader of the Fabian Society, Shaw proposed his radical postulate of equal incomes as a solution to those twin scourges of a modern industrial society: poverty and inequality. Set against the backdrop of Beatrice Webb’s famous Minority Report of the Royal Commission on the Poor Law 1905-1909 – a publication which led to grass-roots campaigns against destitution and eventually the Welfare State – this book considers how Shaw worked with Fabian colleagues, Sidney and Beatrice Webb, and H. G. Wells to explore through a series of major lectures, prefaces and plays, the social, economic, political, and even religious implications of human equality as the basis for modern democracy.
