Ectogenesis
Ectogenesis (from the Greek language, Greek ''ἐκτός'', "outside", and ''wikt:genesis, genesis'') is the growth of an organism in an artificial environment, outside the body in which it would normally be found, such as the growth of an embryo or fetus outside the mother's body, or the growth of bacteria outside the body of a host. The term was coined by British scientist J. B. S. Haldane in 1924. Human embryos and fetuses Ectogenesis of human embryos and fetuses would require an artificial uterus. An artificial uterus would have to be supplied with nutrients and oxygen from some source to nurture the fetus, as well as dispose of waste material. There would likely be a need for an interface between such a supplier, filling this function of the placenta. As a replacement organ, an artificial uterus could be used to assist women with damaged, diseased or removed uteri to allow the fetus to be conceived to term. It also has the potential to move the threshold of fetal viability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek (, ; , ) is an Indo-European languages, Indo-European language, constituting an independent Hellenic languages, Hellenic branch within the Indo-European language family. It is native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the list of languages by first written accounts, longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts ...

Embryonic Stem Cell
Embryonic stem cells (ESCs) are Cell potency#Pluripotency, pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-Implantation (human embryo), implantation embryo. Human embryos reach the blastocyst stage 4–5 days post Human fertilization, fertilization, at which time they consist of 50–150 cells. Isolating the inner cell mass (embryoblast) using immunosurgery results in destruction of the blastocyst, a process Stem cell controversy, which raises ethical issues, including whether or not embryos at the pre-implantation stage have the same moral considerations as embryos in the post-implantation stage of development. Researchers are currently focusing heavily on the therapeutic potential of embryonic stem cells, with clinical use being the goal for many laboratories. Potential uses include the treatment of diabetes and heart disease. The cells are being studied to be used as clinical therapies, models of genetic disorders, and cellular/DNA r ...

Shulamith Firestone
Shulamith Bath Shmuel Ben Ari Firestone (born Feuerstein; January 7, 1945 – August 28, 2012) was a Canadian-American radical feminist writer and activist. She was a prominent figure in the early development of radical feminism and second-wave feminism and a founding member of three radical feminist organizations: New York Radical Women, Redstockings, and New York Radical Feminists. Within these movements, she was referred to by some as "the firebrand" and "the fireball" due to the intensity with which she advocated for feminist causes. In 1967, she spoke at the National Conference for New Politics in Chicago. In 1968, she organized a symbolic event referred to as "The Burial of Traditional Womanhood" and participated in the Miss America protest later that year. She protested sexual harassment at Madison Square Garden, organized abortion speakouts, and disrupted abortion legislation meetings. In 1970, Firestone published '' The Dialectic of Sex: The Case for Feminist Revolu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Dialectic Of Sex
''The Dialectic of Sex: The Case for Feminist Revolution'' is a 1970 book by the radical feminist activist Shulamith Firestone. Written over a few months when Firestone was 25, it has been described as a classic of feminist thought. Firestone argues that the "sexual class system" predates and runs deeper than any other form of oppression, and that the eradication of sexism will require a radical reordering of society: "The first women are fleeing the massacre, and, shaking and tottering, are beginning to find each other. ... This is painful: no matter how many levels of consciousness one reaches, the problem always goes deeper. It is everywhere. ... feminists have to question, not just all of ''Western'' culture, but the organization of culture itself, and further, even the very organization of nature." The goal of the feminist revolution, she wrote, must be "not just the elimination of male privilege but of the sex distinction itself" so that genital differences no l ...

Bodily Autonomy
Bodily integrity is the inviolability of the physical body and emphasizes the importance of personal autonomy, self-ownership, and self-determination of human beings over their own bodies. In the field of human rights, violation of the bodily integrity of another is regarded as an unethical infringement, intrusive, and possibly criminal.Communication Technology And Social Change Carolyn A.

Abortion Rights
Abortion-rights movements, also self-styled as pro-choice movements, are movements that advocate for legal access to induced abortion services, including elective abortion. They seek to represent and support women who wish to terminate their pregnancy without fear of legal or social backlash. These movements are in direct opposition to anti-abortion movements. The issue of induced abortion remains divisive in public life, with recurring arguments to liberalize or restrict access to legal abortion services. Some abortion-rights supporters are divided as to the types of abortion services that should be available under different circumstances, including periods in the pregnancy such as late term abortions, in which access may or may not be restricted. Terminology Many of the terms used in the debate are political framing terms used to validate one's stance while invalidating the opposition. For example, the labels pro-choice and pro-life imply endorsement of widely held va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abortion Law
Abortion laws vary widely among countries and territories, and have changed over time. Such laws range from abortion being freely available on request, to regulation or restrictions of various kinds, to outright prohibition in all circumstances. Many countries and territories that allow abortion have Gestational age, gestational limits for the procedure depending on the reason; with the majority being up to 12 weeks for abortion on request, up to 24 weeks for Pregnancy from rape, rape, incest, or Socioeconomic status, socioeconomic reasons, and more for Birth defect, fetal impairment or risk to the woman's Complications of pregnancy, health or Maternal death, life. As of 2022, countries that legally allow abortion on request or for socioeconomic reasons comprise about 60% of the world's population.

Fetal Viability
Fetal viability is the ability of a human fetus to survive outside the uterus. Viability depends upon factors such as birth weight, gestational age, and the availability of advanced medical care. In low-income countries, more than 90% of extremely preterm newborns (less than 28 weeks gestational age) die due to a lack of said medical care; in high-income countries, the vast majority of these newborns survive. Medical viability is generally considered to be between 23 and 24 weeks gestational age, meaning that these newborns have a < 50% chance of either dying or surviving with severe impairment if active care is instituted; this applies to most fetuses at ≥ 24 weeks of gestation, and to some fetuses at 23 weeks of gestation with favourable risk factors. As of 2022, the world record for the lowest gestational age newborn to survive is held by Curtis Zy-Keith Means, who was born on 5 July 2020 in the United States, at 21 weeks and 1 day gestational age, weighing 420 grams ...

Abortion Debate
The abortion debate is a longstanding and contentious discourse that touches on the moral, legal, medical, and religious aspects of induced abortion. In English-speaking countries, the debate has two major sides, commonly referred to as the "pro-choice" and " pro-life" movements. Generally, supporters of ''pro-choice'' argue for the right to choose to terminate a pregnancy. They take into account various factors such as the stage of fetal development, the health of the woman, and the circumstances of the conception. By comparison, the supporters of ''pro-life'' generally argue that a fetus is a human being with inherent rights and intrinsic value, and thus, cannot be overridden by the woman's choice or circumstances and that abortion is morally wrong in most or all cases. Both the terms ''pro-choice'' and ''pro-life'' are considered loaded words in mainstream media, which tend to prefer terms such as "abortion rights" or "anti-abortion" as more neutral and avoidant of bias.

Bioethical
Bioethics is both a field of study and professional practice, interested in ethical issues related to health (primarily focused on the human, but also increasingly includes animal ethics), including those emerging from advances in biology, medicine, and technologies. It proposes the discussion about moral discernment in society (what decisions are "good" or "bad" and why) and it is often related to medical policy and practice, but also to broader questions as environment, well-being and public health. Bioethics is concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, theology and philosophy. It includes the study of values relating to primary care, other branches of medicine (" the ethics of the ordinary"), ethical education in science, animal, and environmental ethics, and public health. Etymology The term ''bioethics'' (Greek , "life"; , "moral nature, behavior") was coined in 1927 by Fritz Jahr in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants.
