Oocyte Cryopreservation A recent New York Times article titled "For Women Worried About Fertility, Egg Bank is a New Option" written by Sally Wadyka, focuses on the new improved technology of Oocyte cryopreservation, or the freezing of eggs. It has become a recent trend for women to wait till later in their lives to start a family. Until recently, there was no procedure available for women to store their eggs to be used at a later date. Because of this trend and the new advances in the field of
Cryogenics Cryogenics is a largely growing field, relatively innovative in the field of science and research. It deals with freezing temperatures below –150 degrees Celsius (-238 degrees Fahrenheit) using oxygen, helium I, helium II (which are both are chemically identical), and nitrogen. These are cooled to the point of liquidation and used to freeze diverse materials and substances. “At these extreme conditions, such properties of materials as strength, thermal conductivity, ductility and
Cryobiology: Low Temperature Studies Of Biological Systems Thesis: Low temperature biology, or cryobiology, has the possibility, and may very easily and very drastically affect everyones' lives in the future. Through rapidly approaching cryobiological medical procedures and techniques, the presence of intense ethical issues may play an important role in many everyday decisions that do not now exist. Introduction What is cryobiology? It is "the study of the effects of freezing and low
Scientific Contemporary Issues Report Cryonics What is Cryonics? Cryonics is a procedure whereby a person or living organism is frozen soon after death in order that it may be thawed and rejuvenated at a later date should a cure for the cause of death be found. A person or living organism that is preserved by the process of cryonics is said to be in cryonic suspension. In order to understand the true nature of cryonics it is wise to give a simple example of what scientists are attempting to achieve
Genetic Engineering and Cryonic Freezing: A Modern Frankenstein? In Mary Shelley's Frankenstein, a new being was artificially created using the parts of others. That topic thus examines the ethics of "playing God" and, though written in 1818, it is still a relevant issue today. Genetic engineering and cryogenic freezing are two current technologies related to the theme in the novel of science transcending the limits of what humans can and should do. Genetic engineering is widely used
Cryonics Suzie Q, a twenty-five year old woman, is dying of AIDS. When she learned this, she heard about something called cryonic suspension. A cryonist at the hospital where she gets treatment told her how cryonics freezes people when they are pronounced dead. When the cure for AIDS is developed, she would then be revived and able to start a new life. Suzie Q decided to participate in cryonic suspension and spent her life savings to pay for the freezing process. Five years later, Suzie Q died
The False Hope of Cryonics Have you ever thought about living one hundred years or more from now? If current beliefs are proven to be possible it may be a possibility in the future. Alcor, a life extension foundation, claims that Cryonics may make it possible for people who die to be revived in the future. Just think about it, you could get to see how present problems were solved in the future. The only catch is that Cryonics may cause more problems than it can solve in the future. Cryonics

recognized in the early nineteen sixties. Cryobiology is the study of the effects of extremely low temperatures on living animals and plants. The chief concern in cryobiology is to preserve living matter for future use. This method can also be called cryopreservation. Cryotherapy is the use of extreme cold in treatment. The first trials of cryotherapy proved with great results (“Cryobiology” Comptons 1, McGrady 97). Frozen cells can be kept alive for very long periods of time in a state of “suspended animation
The cell plasma membrane, a bilayer structure composed mainly of phospholipids, is characterized by its fluidity. Membrane fluidity, as well as being affected by lipid and protein composition and temperature (Purdy et al. 2005), is regulated by its cholesterol concentration (Harby 2001, McLaurin 2002). Cholesterol is a special type of lipid, known as a steroid, formed by a polar OH headgroup and a single hydrocarbon tail (Wikipedia 2005, Diwan 2005). Like its fellow membrane lipids, cholesterol
The role offered me both routine and research and development responsibilities and I learned a diverse skill sets in the capacity. Following an established and validated SOP to run the Natural Killer Cytotoxicity assay on patient whole blood, cryopreservation, performing several enzyme immunoassays, while also maintaining several different cell line cultures on a daily basis were some of the responsibility the routine role afforded me. Furthermore, I was charged with daily and periodic maintenance
Gender and the Internet The internet can be a very good source of information, but it can also altar information enough to make it unreal. Feminist sites are no exception to this. Many sites in fact use virtual rendering to altar images in addition to text. There are various topics dealing with feminism and issues involving females, some are well approached and others are not. Women do not tend to have the same type of relationship with their automobiles as men do. In Virginia Scharff’s
Umbilical cord blood (UCB) is an important source of haematopoietic stem cell now being used for transplantation. It contains stem cells that are unique; smart and are capable of treating several diseases such as haemoglobinopathies, leukaemia, immune system deficiencies and many genetic diseases4. However, until recently in most cases the cord blood was discarded as medical waste, although now it is considered the hidden treasures of life. Since the first successful UCB transplant to a sibling with
Bioethics Issues: Cryonics Cryonics is the process in which an individual is dehydrated and then cryopreserved immediately after death, with hopes for the individual to be reanimated in the future. The promise of life after death, though gaining momentum and popularity, is also gaining skepticism. Cryonics is unethical. Not only is it extremely expense, those practicing cryonics can not ensure if the process even works. Furthermore Cryonics disregards Christianity. Large cryonics companies such
In my opinion, In vitro fertilisation (IVF) is one of the greatest breakthroughs in Medical Biotechnology in the last 50 years. Finding out you are infertile can be heart-breaking and distressing. After trying for long periods of time, some couples are not able to conceive. Thankfully, this problem many couples have can be fixed by In Vitro Fertilization (IVF), a process that was developed and used in Britain first more than 30 years ago by Doctors Patrick Steptoe and Robert Edwards. In 1978, the
Biological immortality There are several methods of achieving immortality, each with its own problems. The first of this methods is to reverse or stop aging, as this is logically one of the main causes of death. In scientific terms this is called biological immortality. A cell or organism that does not age, or stops to age at some point, is biological immortal. Though this seems impossible there are in fact some species which naturally have this ability. An example of this is the Turritopsis nutricula
To put my purpose across, it’s only fair to start from the beginning, the experiences that have given me the purpose. As I grew up, my family faced infertility challenge, and this propelled me to pursue studies related to human fertility to help others rather than watching them suffer helplessly. In the course of my practice, I perceived that knowledge I possess is still inadequate to solve the issue abundantly hence the choice to further my studies on the same. My academic background gave me a
There is nothing more devastating than trying time after time to conceive and coming up empty just see the doctor and be told that either you or your spouse are infertile. Infertility is a heavy blow to anyone who wishes to have a family of their own and can take quite a toll on a relationship. More than 15% of the population worldwide suffers from Infertility . People who suffer from infertility are advised about hormone treatments and artificial reproduction therapy, now couples who once couldn’t
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic species, diseases, shifting cultivation, poaching of wild life etc. Since the human beings are enjoying all the benefits from biodiversity
Thousands of babies are born each year to couples who may have never been able to conceive on their own. Dr. Robert G. Edwards is given the credit for developing a procedure called in vitro fertilization, which continues to give hope to couples all over the world. The term “in vitro,” broken down, implies that a process occurs outside of a living organism, therefore “in vitro fertilization” simply means fertilization outside of an organism. This groundbreaking accomplishment is what lead Dr. Edwards
