Technology Ethic: Stem Cells
Stem Cell:
Stem cells can be thought of as blank slates or cells that have yet to become specialized. They can be transformed to become cells with special functions.
History/Background of Stem Cells:
In the mid 1960's, R. G. Edwards and colleagues at Cambridge University began studying differentiation of rabbit embryonic cells in an artificial environment. They manipulated these embryonic cells into specific types of form such as connective tissue and muscle neurons.
Richard Gardner, a graduate student of R. G. Edwards, had furthered the experiment with mice blastocoels. As a result, human blast cysts became available since R. G. Edwards' laboratory in the early 1980s.
In 1986, Peter Hollands, another graduate student of Edwards, demonstrated that mouse embryonic stem cells could colonize and repair damaged tissues of the haematopoietic system in adult mice.
In 1998, James Thomson and colleagues at the University of Wisconsin successfully isolated and grew human embryonic stem cells. At John Hopkins University, John Gearhart successfully isolated human germ cells.
From 1999 to 2000, researchers continued to manipulated cells from adult mouse tissues.
Types Of Stem Cells:
Stem cells can be classified into tree main types:
oEmbryonic Stem (ES) Cells
oEmbryonic Germ (EG) Cells
oAdult Stem (AS) Cells
Embryonic Stem Cell:
ES cells are undifferentiated cells derived from the inner cell mass of the blast cyst. They are the original cells of our body tissues. ES cells have the potential to transform into 200 different specialized cell types.
Human embryonic stem cells are derived from fertilized embryos which are less than a week old. In November of...

...ind. A young woman paralyzed in a car accident now can move her legs and toes as a result of having her own immune system cells injected into her spinal cord. Two children born without immune systems now have functioning ones because of a bone-marrow stem cell treatment. After analyzing stem cell development, I feel that research on ES cells should be stopped because of the many risks involved. Whereas the research on AS cells should carry on for it opposes no hazard to anyone.

Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.
For as long as I can remember, my childhood dream has always been wanting to become a veterinarian. While other kids were outside having fun at the playground, I was at the library reading books and learning about the different animals. However, as I matured, I realized that being a veterinarian isn’t just about caring for and assisting injured animals. Being a veterinarian means having the ability to make quick decisions in stressful situations, showing complete dedication and passion to this profession, and being able to effectively communicate to pet owners.
In addition to helping sick animals, another option for veterinarians is doing scientific research and trying to make new medicines (Fact Monster).
A career in occupational therapy is challenging, yet rewarding. Someone who is a people person would enjoy the constant interaction with clients and families. After studying this career, it is extremely apparent that all occupational therapists have one thing in common; a love for people and healing.
Veterinarians are doctors that take care, treat, and help the animals that are severely ill, and even take part in human activity. This career is perfect for someone who has the right skills and qualifications, including personality and attitude and one who can deal with any working conditions that this job has to offer. Being a veterinarian has its benefits and drawbacks, and just like any other career, you need the proper requirements to pursue it.
During recent observation hours, I heard some of the most influential words of advice from an occupational therapist which was “Occupational therapy is fun.” It is a simple thought, yet it is so true. Occupational Therapy is not a healthcare field where you just prescribe medications. It is a career where you help older adults enjoy the activities they love again. It is a career where you help children be attentive at school and confident at the dinner table. It is a career where you dedicate time to understanding and encouraging patients in ways that are specific to their needs and goals. With occupational therapy, you create an individualistic approach to a patient’s plan of care. It is a career where you make a real difference, and because I want to create change and help others, I want to be an occupational therapist. I am so excited by the diverse and meaningful nature of the work, and I cannot wait to begin this journey.
Weddings today are much more different then marriages of the past. Many of the customs from then have made their way to this era but also many haven’t. we can see many differences and also many similarities. The biggest difference is the control of marriages and the arranged marriages that took place. In today’s culture we are not grouped by social stature as they were then, our marriages are based on love not class. I think this is a good thing and I am happy to be blessed by God to be able to have the freedom of choice in something as important and life changing as a marriage.
Hours are long and the work is high pressure. The job requires complex responsibilities and decision making. The needs of the animal and those of the owner do not always overlap perfectly, and decisions concerning treatment must be made to best balance the needs of both. In this way, veterinarians act as the gatekeepers of both human and animal welfare. My passion is to play an active role in improving the lives of both my animal patient’s and their human owners. In doing this I believe I will be able to fulfill my drive to help animals that was born out of the devastation I experienced in Japan.
Occupational therapy oriented my religious upbringing and principles with the desire to improve the health and welfare of others. It provided me with the an avenue in which I could help others regain control over aspects of their life that were lost and thus provide hope. Occupational therapy is defined as “helping people across the lifespan participate in the things they want and need to do through the therapeutic use of everyday activities”. The inherent value of occupational therapy is often underestimated and passed over. Occupational therapists do everything from helping children with disabilities so that they can fully engage in school activities to helping those who lost bodily functions in accidents to recover usage of their limbs.

Even though the journey to becoming a veterinarian will be a long and rigorous road ahead, in the end, it will all be worth it. Sixty five percent of animals around the world die from abuse or improper treatment, and as a future veterinarian, I want to start putting a stop to it now. “The greatness of a nation and its moral progress can be judged by the way its animals are treated.” –Mahatma Gandhi.

Imagine yourself saving animals one day at a time. It might be hard, but you will get that amazing feeling of knowing you did something good for someone else. Veterinarians are a key role in society now a day. People don’t realize all the good they do for the public. Duties, tasks, qualities, salary, benefits, attire, education, and working conditions are major components in deciding whether you could do this job.
Future teachers will all have to reach a certain level of education and certification. Educational requirements can vary greatly depending on the state, but all states require completion of an approved teacher training program and a bachelor’s degree. Many states may require a minimal GPA and additional technology training including, a set number of education and subject credits. A small number of sates necessitate a master’s degree taking up to two years more of schooling than a bachelor’s degree. Other requirements could be student teaching which a lot of colleges offer. Usually for a semester student teachers will work beside an experienced teacher by observing and helping children in ...
