2024 BEST INDIE BOOK AWARDS WINNER IN MEDICINE!2024 GLOBAL BOOK AWARDS SILVER MEDAL WINNER!KIRKUS REVIEWS SAYS "GET IT!"A thrilling synopsis of the current condition of the fight against cancer… A marvelous book that's packed with knowledge, insight, and hope” -Kirkus ReviewsThe American Cancer Society estimates that approximately 2 million Americans will receive a new cancer diagnosis in 2024, with approximately 611,000 cancer-related deaths. These statistics are irrefutably staggering; yet, now, more than ever, there is reason for hope.In Taming Cancer, a biochemist and immunologist with 37 years of experience in the biotechnology industry developing innovative cancer medicines provides an insider’s view of how immunotherapy and other newly emerging therapeutics are changing the lives of cancer patients today by improving both the quality and duration of their lives and, for the most fortunate of patients, totally eradicating their tumors, thereby achieving the “Holy Grail” of cancer medicine: the long-sought cure for cancer. In an engaging narrative covering two centuries of biological discovery, Dr. Kelner describes how these astonishing “living drugs,” which are comprised of engineered viruses, cells, and proteins (such as monoclonal antibodies), target the root causes of cancer and stimulate the immune system to seek out and destroy tumors. Taming Cancer sends a message of hope to current and future cancer patients the world over by presentinga lucid vision of a timewhen a diagnosis of metastatic cancer is no longer by default a harbinger of impending suffering and death. Expertly written in accessible language for readers interested in developing a conceptual understanding of cancer and what can be done to confront it, the book also provides extensive scientific commentary in the endnotes for biology students, medical and graduate students, physicians, nurses, allied health care professionals, scientists, and anyone else interested in learning more about the fascinating and mysterious realm of the human cancer cell.Additional Praise for Taming Cancer:"A" rating from Booklife by Publisher's Weekly: "Kelner proves a welcoming guide whose optimism is infectious. This book bursts with good news." A Reedsy Discovery "Must Read": "Kelner's... writing shines in its ability to distill complex scientific concepts into accessible language, making the content valuable for both laypersons and professionals."

Male - Female - Straight - Gay - Cis - Trans ~~ How? Why?How did I become a male or female? Is there a male brain or a female brain?Why are some people trans? Why are some people gay?Gender is one of the most vital issues of our day. Unfortunately, widespread misunderstanding and misinformation about the nature of gender hinders productive conversation and intelligent policy.An excellent starting point for these discussions would be a good understanding of how we got this way. Many essential questions can be clarified by the current scientific understanding of how we develop our sex and gender, including:How do our masculine or feminine traits develop?What is the role of our genes, our hormones, and our upbringing when it comes to determining our masculine or feminine traits?Why are some people straight and some people gay? Why are some people cis and some people trans?This book was written to answer these questions and explain to a broad audience how gendered traits in our bodies, brains and personalities develop. It was written with the belief that it is possible for most of us to understand the processes that lead to our sex, our masculine and feminine traits, our sexual orientation, and even our gender identities. It explores how nature and nurture impact our development, both before and after we are born. It discusses the impact of our genes, our hormones, and our environments on these processes.This book provides an accessible description of how our traits can masculinize or feminize—especially our personality traits. It addresses the different factors involved, from the role of hormones on our developing brains as fetuses, to the role of parenting and culture. It describes a variety of traits including interests such as auto mechanics or ballet dancing, capacities such as empathy or violence, behaviors such as how we move or throw objects, as well as our self-perceptions and our sexual attractions.There is currently substantial conflict in our societies about how we should approach sex and gender. The hope is that these discussions will be more fruitful if they are based on up-to-date knowledge and understanding of the basics. Furthermore, the facts about how we develop as humans are both fascinating and awe-inspiring. It is truly valuable to understand how these human traits develop, with an appreciation for our vast human similarities as well as our vast individual differences. Read more

Fifty years ago the field of human embryology was incomplete; prior to that time the anatomy of early human embryos was still unknown, and there was much to be learned about the older stages of human embryonic development. It is now understood that human organs result from step-by-step differentiations of the growing human embryo. Research by renowned embryologist Erich Blechschmidt, MD, showed that differentiations are not only the result of a gene effect, but are also brought about through growth initiated by extragenetic (occurring outside the gene) information. Without this extragenetic information the differentiation would not begin.   Dr. Blechschmidt and coauthor Raymond Gasser, PhD, maintain that Haeckel's biogenetic law (ontogeny recapitulates phylogeny) was an erroneous attempt to explain developmental processes. Blechschmidt's human embryological investigations showed that Darwin's principles (mutation and selection) are likely valid for the origin of the species, but that they cannot explain the ontogenesis of the organs. The ontogenesis of each individual cannot be derived from phylogenetic facts. The authors stress that a clear distinction must be made between the vast field of phylogenetics and the much more exact and understandable field of ontogenetics—particularly the process of differentiation—and their goal is to present not only the abstract biokinetic principles of differentiation, but the originality of embryonic human beings as well. Their knowledge of developmental movements leads to their conclusion that differentiation is an undivided biodynamic process that occurs during development and includes the chemical processes as well.   Logically organized into two sections (the first covers early metabolic fields and includes chapters on the one-cell human ovum, the early embryo, blood vessels, the nervous system, head region, trunk, and limbs; the second describes metabolic fields in later developmental stages, distinguishing fields of corrosion, densation, contusion, distusion, retention, dilation, liquation, and detraction), Biokinetics and Biodynamics of Human Differentiation warrants reading by thoughtful professionals in a number of fields concerned with embryonic differentiation. A new preface by Dr. Gasser addresses how the book's principles and findings were and are understood in the field of human embryology. Read more
