94 Results for stem cell

Ever since human stem cells were first isolated, research on stem cells has received much public attention, both because of its extraordinary promise and because of relevant legal and ethical issues. Stem cells are self-renewing, unspecialized cells that can give rise to multiple types all of spec...
The recent death of Ronald Regan from Alzheimer\'s disease has generated an explosion in the field of stem cell research. Scientists wonder if stem cells implanted in Regan\'s brain could have helped improve the status of his Alzheimer\'s or even cure it. Stem cell research was brought to attention ...
Before giving this assignment to work on I was 100 percent against stem cells research. But due to extension research I found out that stem cells can provide us with a myriad of possibilities in medical technology, but not without bringing with it serious moral and ethical dilemmas. For the s...
The research of stem cell biology has introduced possibilities of cellular replacement strategies, which, if successful, could create effective treatments for diseases such as Parkinson\'s Disease and Diabetes (type 1), as well as repairs to severe spinal cord injuries that were previously untreatab...
Stem Cell Controversy The history of medicine was forever changed in November of 1998 by the discovery of stem cells. Throughout medical history humans have strived to understand the many functions of the human body. From the first operation ever performed, to the sequencing of the human genome, s...
Thousands of Americans face trouble doing regular work around the house. Most of them have difficulties using scissors, can no longer do extracurricular activities, and have to take several expensive prescription medications just to ease the uncontrollable tremors in their muscles. Thes...
Should Embryo Stem Cell Research Be Banned? This is one of the most controversial questions posed in the last century. The issue is simple. Should the federal government fund embryo stem cell research? The answer is extremely complex. At the heart of this controversy, is whether or not, i...
Negative Consequences of Stem Cell Cloning In Alclous Huxley's science-fiction novel Brave New World the characters speak of a process they call budding . The description of budding has recently popped back into society. Only in today's terminology it is called stem cell cloning. The ch...
Cloning and stem cell research, which have been a big issue ever since Hans Spemann first raised the question of nuclear equivalency in 1938. The controversy behind cloning is that this will give scientists too much power, and many people believe that cloning should not be allowed because it is aga...
Bioethics and Genetic Engineering By the year 2025, the world's population will be approximately 7.4 billion people and 2 million clones. What seems like something from a bad science fiction movie could, indeed, be a reality based on how quickly technology is growing in the area of...
Cloning: Problems and Controversies Human and Animal Cloning has been a big issue over the last few years. Thought the processes and procedures have been in testing for over a hundred year. The first Cloned animals were frogs in the 1950's (Daniel Cohen 12). The techniques ...
IVF
1.0 INTRODUCTION In Vitro Fertilisation (IVF) translates to the term 'in glass (vitro) fertilisation' essentially it is a technique whereby egg cells are fertilized outside the mother's body due to conception being impossible by normal sexual intercourse. There are many issues concern...
Since the late seventies scientists have been cloning mammals using cells taken from embryos. In July 1996, medical history was made when a sheep named Dolly was cloned. The only thing that set Dolly the sheep apart from the other clones was that she was cloned from an adult sheep cell. Befor...
A process that has been researched and debated for decades, and for a while thesubject of science fiction novels, magazines, and television shows, is today a practicalreality. News of successful cloning of an adult sheep generated an outpouring ofethical concerns in 1997. These concerns were not a...
ABSTRACT In my study, I wanted to see if I could breed a trait (Longer petial stem length) in Brassaca rapa by following an artificial selection design. The study was also used in order to monitor the mechanisms of evolution. To do this, I wanted to see if cross pollinating plants with the trait I ...
More than one celled organisms grow by way of mitosis and the cytoplasmic division of body cells. On the other hand, meiosis occurs only in germ cells, which are put aside for the formation of gametes (sperm and egg). Reproduction by meiosis allows for species survival and it increases genetic v...
Cell theory- all organisms are made of one or more cells and the products of those cells. An organism may be a single cell, such as a bacterium, or many cells organized to function together as in an animal or plant. In many celled organisms, there may be intercellular material made by the cells. All...
In this day and age Cloning is a large topic. This topic entails many moral and ethical issues. Cloning research is being done across the world and has been preformed many times with animals and humans. Why is cloning such a touchy topic? Is it because are people afraid of a modern day Frankenst...
There are many scientific benefits to cloning. Cloning is defined as the making of a precise copy of a molecule, cell, or individual plan or animal. The scientific benefits of cloning are endless and know no boundaries. The reason that it knows no boundaries is because not all forms of cloning a...
Cloning: The production of genetic copies. &Clones: A group of genetically identical organisms.Ever since the belief that cloning was a possibility, and especially since it has been developed, it has been a major conflict in the ethical world of values. There are many different pros and cons about ...
B16 FACTORS AFFECTING GERMINATION OF SEEDS Aim: To prove the factors that affect germination Hypothesis: 1. Control: This experiment has the 4 factors that are necessary for germination. Its conditions are going to be the appropriate ones and this experiment is going to grow and develop c...
Trace the pathway in a flowering plant as the water moves from the soil through the tissues of the root, stem, and leaves to the atmosphere. Explain the mechanisms involved in conducting water through these tissues. A very basic overview of water through a flowering plant starts at the roots. Th...
Human Cloning Human cloning The billions of cells that presently make up a human being descend from one single cell, the fertilized egg. Today, there is a new way of creating life, cloning. Cloning can mean anything from the growing of healthy cell tissue to replacing damaged tissue in th...
Research Paper: CloningToday, humankind lives in a world of technology, technology that is rapidly advancing and presenting more ways to improve life. The cloning of animals and humans are part of this technology, parts which can ultimately lead to the reassurance and pro-longing of life as we now k...
During his time in office, President George W. Bush has led the American people through trials and hardships unseen since Franklin D. Roosevelt's presidency: An attack on American soil. Through his devotion to the safety of America in the War on Terrorism, as well as his attention to key do...
