Dr. Elizabeth Ables is an assistant professor at East Carolina University, in Greenville, North Carolina. She has worked there since 2013. Dr. Ables received her BS degree from St. Andrews University and her Ph.D. in Molecular Physiology and Developmental Biology from Vanderbilt University. She studied how the pancreas precursor cells are led by a cascade of transcription factors during development to become insulin-producing beta cells, while using transgenic mice and immunofluorescence microscopy to examine the topic. Her current studies resulted in the discovery that the steroid hormone ecdysone, which directly controls Drosophila germline stem cell activity. These studies expanded her ability to design experiments significant for …show more content…
We learned tissue homeostasis is a balance between cell division, specialization, and turnover time. Normal cells have a plethora of specialized cells and with proliferation there tends to be a loss of specialized function. Her interest in stem cells came with some problems. First, all cells come from other cells. Secondly, specialized cells tend to divide very infrequently. Therefore, she began studying the germline cells of fruit flies because the cell cycle is very similar to humans. She wanted to study stem signals and their complex connections to determine the cell fate. Such as in the Drosophila uterine cells, there is a cluster of cells in which only one will become the final egg cell, the others are nurse cells that monitor the egg. The fate of these cells is predetermined by genes and were illustrated through immunofluorescence microscopy. During her presentation she held the attention of entire audience with the use of direct eye contact, and did not need to look at note cards or reference the slides unless directing the audience through a figure. She also spoke with respectable volume and articulation to keep the audience interested and emphasize key points. I like that she moved around a bit while she spoke. She also made the class very informal, which helped to make it more comfortable to ask questions. She seemed very comfortable with her research and could answer all questions presented to her by the audience. She was very knowledgeable and
I liked the questions she asked. Some of them were open ended so she could keep he student interested and involved. She asked the silent student what is his name. She asked a student how old they were and what they did for fun.
Today in class Melinda Laprade came to discuss how our resume should be, and how we should prepare for an interview. Melinda Laprade gave us some helpful insight on how we would go about getting a job and they tools we can use. She went over what to wear and what not to wear to an interview. Also, how you to uphold yourself. A helpful tip that I will be using is creating a mock interview with a friend before the interview. Another one is getting to know the company beforehand so that you can know what they are looking for. I really enjoyed her presentation and there was a lot I didn’t know that she cover. I am glad that she came.
Stem cells are a topic that may be unfamiliar to many people. Before the article is read, the reader knows that the author, Jean Peduzzi Nelson, is well educated on stem cells as she researches and studies stem cells at Wayne State University. This immediately establishes the writer’s credibility before she begins to propose her argument. Nelson’s background greatly strengthens her argument as it shows that she is an expert in the field of stem cells and allows the
Cahona gave a very informative presentation she introduces herself by talking about herself when she was a young child and explaining why she is doing what she is doing, she then goes onto gave informative information on the homeless people in the USA and finally ending by giving statistics. She uses a various ways of captivating the audience by making her voice higher, harder and a bit faster for example when she says
this research would be to identify the factors that are involved in the cell making process that determines cell specialization. A few of our extreme medical conditions, like birth defects and cancer, are a direct result of abnormal cell specialization. If researchers obtain a better understanding of the normal cellular process, they can isolate the causes of these deadly illnesses. The most exciting potential use for stem cells is the generation of tissues and cells. Many diseases are a direct result from complications of cellular functions or destruction of tissues in the body. Many people donate organs and tissues to replace failing or destroyed tissues. Unfortunately, there are many more people suffering from these disorders than there are organs to transplant. That is where stem cells step in. They will give humans a chance to have a renewable source of cells and tissues that will treat a slue of diseases, and disabilities such as, Parkinson’s, stroke, burns, Alzheimer’s, spinal cord injury, diabetes, rheumatoid arthritis, and
Embryonic stem cells (ESCs) are grown in the laboratory from cells found in the early embryo. ESCs have an unlimited chance to
Mrs. Arnold was very well spoken throughout the course of her speaking. She was not boring and was able to keep my attention along with the rest of the class. She was very helpful in the sense that she would explain something further if somebody was lost or had questions to ask. She voice was not monotone and it sounded like she wanted to be there. From the tone of her voice, it sounded like she really liked what she was talking about. She did not stutter or pause at any moment. She really understood what she was talking about and that helped with the follow if her presentation. As far as her physical delivery, she just sort of stood in one place the entire time Whenever she would talk, she would use her hands a lot to put emphasis on
The need for the new changes is something that should had been in place a long time ago. There can be no way society thinks America is being over protective. If this great nation that is called home to more than 300 million people not being alert and ready for anything, it will not be here much longer. The rules that are in place due to the 9\11 acts woke America up…now stay up America!
She has banned two chemicals that can hurt people’s health. Besides that, she is a killer mountain climber! What I liked about her presentation was how straightforward it was. In addition, when she spoke about statistics, she had proof and showed it. After watching her presentation, I became more aware of how many chemicals there are in things we use in our everyday lives. Never before would I have thought that even just by eating, one could harm their health. She intrigued me to learn more about these chemicals and how I can prevent them from harming me. Although I did like most of her presentation, I thought she could have been more professional. She was very awkward during the whole thing. For me, if you are a public speaker, you should not be as awkward at all. Some parts were confusing and I felt as if it had nothing to do with her topic. However, overall, it was a good presentation. When I looked her up, I found a quote that she always says that I thought was very inspirational; “There are storms and avalanches, but you keep plodding up the mountain to make it to the
Many scientists believe that embryonic stem cell (ESC) research is the key to curing diseases such as cancer and HIV. Stem cells are so important to biomedical research because they are primitive cells that are capable of replicating indefinitely producing a multitude of different types of cells. This means that one of these pre-determined cells has to potential of becoming any range of over two hundred tissues with epithelial cells to blood and
She made me want to listen a wonder what would happen next. I think that she added a bit more excitement to her voice and came from behind the podium when ending her speech. Given these points even though Karen Thompson Walker could use some improvement, but we all need improvement to become better public
There were various aspects of the speaker’s delivery that were effective, in her opening part of her speech she was interacting with the audience in their posture stances. This gave many an understanding of what she is trying to show them how posture can change the way an individual view themselves in a third person perspective as well as their confidence build. I myself took a look at my posture and realized that in fold my arms excessively and hunch over to feel more comfortable in a room full of unfamiliar people. On the other side we have individuals who use as much space as possible to show their dominance to others such as spreading out by stretching while standing or sitting. Speaking very clear and making strong eye contact makes her an extremely effective public speaking as she gestures to the things she wants us to focus on as we are talked through her examples. Transitions are very noticeable as slides or videos giving examples as visual representation makes her speech very easy to follow and understand her points effectively. Cleverly using nonverbal examples such as handshakes, eye winking, face to face eye contact as well as physically touching another are very good
Scientists are interested in stem cells for their ability to become any type of cell in the body, a process called differentiation. Theoretically, this allows for limitless possibilities in disease
The ability to trace cell lineages holds a massive amount of beneficial information for the medical community, biologists, and genetists. John Sulston started this revolution with his 1980s research over an embryo of Caenorhabditis elegans. Sulston traced the cell lineage of this organism from fertilization until multicellular development. In his observations, he recorded the development of 671 cells and the death of 111 cells. Understanding the history of where the cells come from has the promise to lead to innovative technologies which have the possibility to change the future of medicine.
