Major Writing Assignment Analysis
The main purpose of the first major writing assignment is to show you understanding and knowledge of the characteristics of writing in your profession and then, condense that understanding and knowledge into a one sentence statement about the role of writing in your profession. The audience, or the person you are writing towards is a, group of high school/college students looking into your intended profession. As for the genre type, the goal is to write and informal report to these students. In this situation your stance is neutral, you are just supposed to inform the students and make them more aware of writing in the profession. Also, the media is print because the report must be typed on a computer, and the design of the informal report is in APA format.

Rhetorical Situation Analysis of high school English paper
I choose to analyze my research paper from junior year on
stem cells. The purpose of the assignment was to inform and persuade an
imaginary audience. Students were to choose a controversial topic and pick a
side to argue within their paper. Within my own essay, I informed people of the
benefits of stem cell research and tried to persuade my audience that the
benefits out way the risks in most cases. As for my audience, we were told to
write like we were giving an important document to executives or government
officials so the paper had to be formal. For example, there were no personal
pronouns in the essay, and all of the arguments made were backed up with
reliable sources. The other audience
member was my teacher, and as a result I format my paper to the teacher's
standard which was MLA standard format. The genre was a formal research paper
so I used a serious tone and again only used researched sourced materials for
information. As for my stance, I choose to take the pro-side of stem cell
research and that can be seen from my thesis statement. I wrote, "Although
many doctors and scientist are skeptical of the uses and benefits of stem cells
research, the research has enormous benefits in the medical field with the uses
of 3-D printers, drug testing, and the potential to reverse diseases with the
stem cell therapies.". The media, or the way information was communicated,
was through the computer. The essay had to be typed and students were limited
to online scholarly articles for sources so, no other forms of media could have
even been use to communicate or get the information.
Paper:
3-D printers provide a unique
and beneficial medical treatment that can help create specific cells and
potentially organs. Researchers from Herriot-Watt University in Edinburgh have
developed a cell printer that creates living embryonic stem cells. The printer
was capable of printing droplet-size cells. These cells printed still
maintained the ability to turn into different cell types (Lewis). This new
printer could be used to create 3-D human tissues that may be used for drug
testing, growing organs, or be printed in the human body directly. Dr. Shu
says, “The manipulability of stem cells (hESCs) make them ideal for use in
regenerative medicine- repairing, replacing, and regenerating damaged cells,
tissues, or organs” –Dr. Shu (Lewis).
Although the printing process might seem easy it is
actually extremely complicated and took years to get right. In a lab dish,
hESCs can be placed in a solution that tells the cells to develop into specific
tissue types. The process begins with the cell forming embryoid bodies, which
can be modeled into a specific shape and size. The printer is made with two
“bio-ink” dispensers: one containing stem cells and the other containing just a
medium. Two inks were dispensed in layers in order to create cell droplets and
then put into small wells. Once the process is finished the wells should have
clumps of stem cells (Lewis). For years scientists encountered trouble with
stabilizing the cells and keeping them alive, but with the new printer made in
Edinburgh the test revealed more promising results. After twenty-four hours,
more than ninety-five percent of the cells were alive. After three days more
than eighty-nine percent were alive (Lewis).
More specifically than just making cells, 3-D printers
have, or will have, the potential for organ, and bone replacement. Some
eighteen people die in the U.S. each day waiting for a transplant (Griggs). 3-D
printers have the ability to reproduce the vascular system required to make
organs useful for transplantation. There is hope that one day 3-D printers
could produce a whole organ such as the liver or pancreas for transplant.
Scientists today are already using the printer to print small strips of organ
tissues. For example Griggs say, “ A 2-year-old girl in Illinois, born without
a trachea, received a windpipe built with her own stem cells” (Griggs). To
create a bone replacement, the printer creates a scaffold in the shape of the
bone, and coats it with stem cells. The benefit of the scaffold is the person
has the ability to organize where the cells are located. This leads to better
blood vessel and bone formation (Lewis). These are just some examples of the
abundances of circumstances where a 3-D printer provided a solution to a
medical problem using stem cells. Without the help of stem cells, 3-D printers
would never be able to create any cell or organ for any use.
Stem cells are expected to dramatically improve the
ability of drug companies to screen for side effects and the effectiveness of
new drugs much earlier in the development process (Accelerate Basic Research).
This would significantly lower the cost and the time frame of developing a new
drug while also saving millions of lives. At the University of Madison,
researchers found a new way to test drug toxicity by monitoring the behavior of
embryonic stem cells introduced to a potential drug candidate (Jennifer Chu).
Testing a drug’s toxicity in lab rats is really unreliable because some drugs
that appear safe in rat can be found to be toxic in humans. Studying stem cells
and drugs could provide a more accurate prediction of a drug’s safety. Gaberial
Cezar, assistant professor at UWM said, “ Exposure to a toxic drug may skew
concentration of molecules that direct cellular metabolism and differentiation,
disrupting cell-to-cell interactions and causing a biological cascade resulting
in potential development disorders” (Jennifer Chu).
The most common drug side effects are on the liver,
kidney, and heart. That is why researchers are using stem cells to use for
testing drugs (Accelerate Basic Research). Drug companies would have banks of
stem cells from people with wide variety of genetic backgrounds and would
provide a similar spectrum as if testing on hundreds of people. This type of
personalized medicine would allow companies to develop safer and more effective
drugs. Also it could reveal groups of people, with the use of their genetic
makeup, that either do or don’t respond well to a certain drug (Accelerate
Basic Research). The main goal is to test the drug on human cells before human
trials and with the research ongoing the future of drug testing looks bright.
Another application of stem cells is making cells and
tissues for medical therapies (Frequently Asked Questions). Therapeutic
treatments with stem cells show enormous potential for diseases related to
genetic disorders. Stem cells are expected to be the most useful in treating
multigenic diseases. Diseases that may be treated by stem cells include: Type-1
diabetes, arteriosclerosis, hypertension, osteoporosis, rheumatoid arthritis,
Alzheimer’s and Parkinson’s Disease (Pearson).
Today, the number of
people needing a transplant far exceeds the number of organs available for transplant
(Frequently Asked Questions). Pluripotent stem cells will hopefully offer a
renewable source of replacement cells to treat many conditions. They are
created by iPS or SCNT and are genetically identical to the donator (Accelerate
Basic Research). Once the cells are created, the hope is they will be used to
treat that person’s medical condition. hESCs are thought to provide potential
cures and therapies for many devastating diseases (Frequently Asked Questions).
Biotechnology companies have built on the basic
foundations to begin creating stem cell- based human therapies (Frequently
Asked Questions). For years many biotechnology companies have conducted
clinical trials to test stem cells. One company is testing the use of human
spinal cord stem cells to treat (ALS) Lou Gehrig’s disease. Another company is
conducting three different clinical trials with Mesenchymal stem cells. The
first tried to protect pancreatic cells in people with Type-1 diabetes. The
second tried to repair the heart tissues after a person has had a heart attach.
Then the third trial was to repair lung tissue in patients with (COPD) chronic
Obstructive Pulmonary disease (Frequently Asked Questions). Bone marrow also
contains stem cells and those have been used and studied for years by
biotechnological companies.
Stem Cells provide a wonderful tool for studying how
diseases develop in the human body (Accelerate Basic Research). For example, if
researchers extracted diseased tissues, drug companies or doctors could use
them to find drugs, treatment, or even reverse the disease. Stem cell
researchers can study the cells to understand what goes wrong when diseases
form in the cell. It could lead to better ways of detecting the disease at an
early stage or help develop treatments (Accelerate Basic Research). Another
example is if a person has Parkinson’s disease, researchers could grow it in a
dish and see what happens as it starts to form. Then they could test different
treatments or even try to manipulate the genes in the cells.
Although many doctors and scientist are not optimistic
about the uses and benefits of stem cell research, the research provides
enormous potential in the medical fields with the uses of 3-D printers, drug
testing, and the potential to reverse disease with stem cell therapies. With
the research collected about stem cells, scientists can save millions of people
suffering from horrible diseases. The research information gained can help
provide new and unique ways of treatment and help researchers understand cells
more extensively. Stem cell research is becoming more common in the medical
field as a way to treat many genetic diseases and conditions. It is being trusted
into the world of modern medicine with enormous expectations, which can be
achieved with continuation of the research.
