Summary:The Knick was inspired by the Knickerbocker Hospital, founded in Harlem in 1862 to serve the poor. In this 20-part TV series spread out over two seasons, the fictional Knick is somewhere in the lower half of Manhattan around 1900. The time covered during the series is not marked in any distinct way. The characters don’t age much, and although fashion and customs remain static during the series, the scope and significance of advancements that come into play were actually adopted over a longer time than the episodes cover.
Summary:The author is a practicing neurosurgeon, one of only two hundred or so women in this specialty which numbers about 4,500. She was the first woman to be admitted to her neurosurgery residency program. Her father was a surgeon and she was definitely influenced by him and says that, as the oldest of four children, it was always expected that she would become a doctor; but she didn't decide for sure until partway through her second year of college.
In a dramatic monologue, Joanne traces the devastation of a familial proclivity to breast cancer through four generations of women: her grandmother Sarah; her mother; Joanne herself and her two daughters, one of whom is also Sarah.
Joanne’s mother and grandmother both died very young of breast cancer; however, many other family members vanished in the Holocaust and the number of familial cancer deaths is insufficient for her to qualify for genetic testing. Her friend Linda, also a mother of two daughters, learns too late that she carries the BRCA gene; she urges Joanne to be tested.
Tormented by not knowing and equally tormented by what should be done if the test is positive—both for herself and her daughters, she convinces a doctor to lie so that the test can be performed. It is positive; Joanne opts for bilateral preventative mastectomies. During a visit to the gravesite of her mother and grandmother, she begins to explain the genetic risk to her daughters.
Summary:The author of this long, compassionate and often startling treatise on identity interviewed over three hundred families to elicit stories about raising exceptional children, stories that also come from these exceptional children ('exceptional' is the term chosen to describe the children in the author's material about the book).
Summary:Rosalind Franklin: The Dark Lady of DNA is the biography of the scientist whose research James Watson and Francis Crick needed to elucidate the structure of the DNA molecule. Even though the discovery has had profound implications for modern medicine, Franklin's contribution to it almost remained obscure.
This is a huge and wonderful book about cancer, the collection of diseases that sickens people all over the globe and kills many of them. An epigraph to the book states, “A quarter of all American deaths, and about 15 percent of all deaths worldwide, will be attributed to cancer,” but the book also describes medical advances that now heal, prevent, or palliate most forms of cancer.
Mukherjee, a cancer physician and researcher, has several strong themes. He sees cancer as an affliction with a long history, a story worthy of a biography; indeed recent discoveries show it to be rooted in our genes (although external factors such as viruses, asbestos, and tobacco smoke can cause genetic disruption). The story of cancer implies a surrounding triangle, the stories of sick people, treating physicians, and biological researchers, all of which Mukherjee artfully weaves across 472 pages. Cancer has Rohrschach blot qualities: depending on time, place, and role in life, humans have perceived different attributes of cancer. As the book ends, however, there is a coalescence of scientific understanding that is satisfying—although there is certainly more to be learned and we are all still vulnerable to genetic errors and, of course, we are intractably mortal.
Another strand is the nature of stories themselves, their twists and turns, presumed early solutions, and personal and social values embedded in them. Mukherjee threads throughout the book the case of a contemporary kindergarten teacher, Carla Reed, who has a leukemia. He bookends his text with ancient Persian Queen Atossa with (presumably) breast cancer. Reed, healed by the end of the book, was Mukherjee’s patient; Atossa was described by Herodotus: both suffered emotional turmoil because of their disease. Mukherjee understands the affective dimensions of disease for patients and caregivers alike; literature represents these in various ways, and he quotes in his chapter epigraphs and in his prose many writers who describe human experience deeply: Aleksandr Solzhenitsyn, Susan Sontag, Charles Dickens, Thomas Mann, William Carlos Williams, Carlo Levi, and Italo Calvino, to name a few.
The primary story, however, is the interplay of cancer and a large cast of observers, investigators, doctors, scientists, activists, and government officials. Sidney Farber and Mary Lasker dominate the first 100 pages with their two-decade war against cancer. While surgery—historically dramatic and disfiguring—had been a mainstay for treatment of cancer, Farber pursued a biochemical route, which elaborated into chemotherapy, the second major approach of the late 20th century.
Mukherjee also explains ancient views, Hippocrates’, Galen’s humors, Vasealius’ anatomy, Hunter’s stages, Lister’s antisepsis, and Röntgen’s X-rays, which became the third major approach. By 1980, however, the American “War on Cancer” had not been won.
Further advances in cellular biology and genetics would be needed to make targeted molecular therapy possible. Mukherjee tells this complicated story clearly and engagingly, showing the human investigators to be personable and dogged in their pursuits.
Another important approach is prevention. The biostatistical work of Doll and Hill, for example, showed the links between tobacco and lung cancer. Screening, such as Pap smears and mammograms, also saved lives, but the basic cellular understanding still eluded investigators.
The final 150 pages explain the search for and discovery of genetic factors, specifically oncogenes. Harold Varmus and J. Michael Bishop were the leaders, winning a Nobel Prize in 1989. Bert Vogelstein, Judah Folkman, Robert Weinberg and Douglas Hanahan took the work further, opening the doors for such drugs as Herceptin, Gleevec, and Avastin.
In 1951 when Henrietta Lacks was dying of cancer in the colored ward of Johns Hopkins, cancer cells taken from her without her knowledge "became the first immortal human cells grown in a laboratory"(4). Known as HeLa cells, they are still reproducing today and are used world wide in research for cancer, cloning, genetics, Parkinsons, and many technologies. Henrietta's family did not know she was the source of these immortal cells until scientists began testing the family members too. Poor and black, they were very angry to find the white establishment had made fortunes using HeLa cells while the family got nothing for it and couldn't even get good health care. In her thorough and careful investigation, Rebecca Skloot interviewed the Lacks family; scientists, doctors, and others who worked with HeLa cells; historians; journalists; ethicists. This book traces the complex stages of her search for the truth about what happened to Henrietta Lacks, her HeLa cells, and her family.
In May of 1944 the author, a Hungarian Jewish physician, was deported with his wife and daughter by cattle car to the Nazi concentration camp, Auschwitz. This memoir chronicles the Auschwitz experience, and the German retreat, ending a year later in Melk, Austria when the Germans surrendered their position there and Nyiszli obtained his freedom. The author describes in almost clinical detail and with alternating detachment and despair what transpired in the crematoria and the dissecting room during his tenure as chief pathologist working directly under Dr. Josef Mengele.
From the first, Nyiszli suspected that there were horrors emanating from the crematoria but he singled himself out from a group of physicians by deciding to "[break] ranks" when Mengele asked those with forensic training to identify themselves. This act secured his survival: the remaining physicians, none of whom stepped forward, all soon perished, while he was assigned to the Sonderkommandos--the prisoners who carried out the exterminations, and who were themselves regularly exterminated to prevent the truth from becoming known. He writes, "As chief physician of the Auschwitz crematoriums, I drafted numerous affidavits of dissection and forensic medicine findings which I signed with my own tattoo number."
At times self-congratulatory about his forensic expertise, at times forcing himself to witness atrocities which he could have avoided, occasionally finding a way to delay death for some of the inmates, Nyiszli was determined to record what he saw--to bear witness, were he to survive. Uncannily able to read a situation and take advantage of it, the author relates how he managed to get his family out of Auschwitz just before they were scheduled for annihilation. Even in the final weeks of the war, when he and thousands of prisoners trudged on foot for weeks with the retreating German army, many dying along the way, he remained shrewdly assertive--and lived.
Summary:Extraordinary Measures, based on events in the life of John Crowley and his family, dramatizes the father's quest to find a cure for Pompe disease, a relatively rare genetic condition that afflicts two of his three children. The quest brings into play three powerful, often competing human motives: a father's love for his children, a scientist's pursuit of knowledge and recognition, and a corporation's mandate for profits. Crowley (Brendan Fraser), an energetic marketing executive, and his wife Aileen (Keri Russell) are told that their children Megan (Meredith Droeger), age eight, and Patrick (Diego Velazquez), age six, have reached the upper limits of their life expectancies.
This novel interweaves facts about the history of genetics with compelling fictional characters and plots in two connected stories. The primary story traces the life and work of the fictional Benedict Lambert, brilliant 20th Century geneticist, and an achondroplastic dwarf; his research is to discover the gene mutation which has caused his condition. He is also the great-great-great nephew of Gregor Mendel.
The life and genetic work of Gregor Mendel comprise the second story. Intersecting with Gregor Mendel's 19th Century scientific experiments to artificially fertilize pea plants is Lambert's affair with married librarian Jean Piercey. When Jean becomes pregnant, she decides on termination after learning from Benedict that there is "a fifty-fifty change of ending up like me . . . a second Benedict, another squat and crumpled creature betrayed by mutation and the courtly dance of chromosomes . . . " (180).
By the novel's end, Mendel's work has been published, and dismissed; Benedict Lambert has discovered the location of the gene mutation which causes achondroplastic dwarfism, publishes the results in Nature, and is asked to make a presentation on "the New Eugenics". Jean regrets the abortion, and wants Benedict's child, but a ?normal" one. In an attempt to help Jean in her quest, Benedict uses his genetic knowledge, his laboratory privileges, and his sperm without the knowledge or consent of Jean's husband.
In the lab with eight of Jean's fertilized embryos Lambert must decide: "Four of the embryos are proto-Benedicts, proto-dwarf; the other four are, for want of a better word normal. How should he choose?" The results of this scientific and personal act of fertilization are unexpected and tragic.
