Biomedical Science
Science’s contribution to humanity is utterly inspiring and exceeds that of any other. As civilized beings we rely on scientific advances and perpetual questioning to sustain ourselves. To venture into this path of boundless grounding will be a huge challenge, but the very idea of devoting myself into the versatile field ignites my ambition for Biomedical Science. I believe that the course’s delicate balance between learning and laboratory work, along with its applicability to real healthcare communities will quench my immense zeal for Science.
My predilection for Science began at a young age, but my genuine appreciation for its complexity sparked off in Year 9, when my stereotypical Asian mother signed me up for AP Biology and Chemistry courses for the summer. These courses paved my insight into the diverse mechanisms of the human body and the dynamism by which systems synchronize with one another. From then on I became fully immersed into the realm of science. This is reflected in my IB higher-level choices: Biology, Chemistry and Mathematics. These subjects l...
I aspire to exceed expectations in this field and work with doctors to access possible conditions. As a student who has always been passionate about science and excelled in these areas, I have had the opportunity to share my knowledge while assisting a physics instructor in the laboratory with experiments he plans to introduce in future classes and while tutoring struggling students in Chemistry, A&P, and Statistics. This has been a rewarding experience for me as I desire to see others succeed. This has also allowed me to stay sharp in these areas and has helped me learn to communicate more effectively; both of which will be beneficial to my program. This year, I’ve had the honor of instructing a science club at a private school where I led a group of students through hands-on learning projects and experimentations. Although I demonstrate a strong background in Science, I knew it would be important to gain some medical experience. I was fortunate to be able to volunteer at a local women’s health clinic with the head sonographer beginning August 2017 and continuing for 1 year until classes begin in the
Having described the scenario, this essay will now focus on the anatomy and physiology during Laura’s third stage. After the delivery of her baby, Laura’s uterus continued to contract and retract due to the effect of oxytocin on the myometrium. Herman (2000) and Herman et al. (2002) describe the placental separation in three stages; latent, contraction/detachment and expulsion. During the latent phase Laura’s myometrium begun to contract and retract. During the contraction/detachment phase Laura’s myometrium continued to contract and retract. Therefore, the surface area decreased under the placenta and it detached from the spongy layer of the decidua, consequently exposing the maternal spiral arteries. During the expulsion phase, Laura’s placenta descended into her lower uterine segment and the membranes peeled away from the walls of her uterus. With further contractions of her uterus, Laura’s placenta and membranes descended into her vagina and expelled from it.
Stem cells help us to maintain and heal our bodies, as they are undifferentiated cells, their roles are not yet determined. They have the ability to become anything during early life and growth. Stem cells come from two sources, namely: embryonic stem cells (embryo’s formed during the blastocyst phase of embryological development) and adult stem cells (see figure 3).
Metabolism is extremely altered during the transition period. The prepartum is marked by an accentuated fetus growth (Bauman and Bruce Currie, 1980) and the onset of lactation; however, the postpartum is marked by an increase in milk production over time and deficit on the intake of nutrients. This situation causes a negative balance of nutrients, when the intake of nutrients does not meet the requirements of the animal; more specifically about energy, it is well-known that transition cows undergo negative energy balance (NEB), and it is easily characterized by body weight (BW) and body condition score (BCS) loss. Bertics et al., 1992, and Hayirli et al., 2002, observed that DMI is affected during the prepartum period, showing a decrease of about 30% on the last couple weeks before parturition. After parturition, DMI increases to support mainly the demands for lactation but it is still not enough to meet the animal demands (NRC, 2001). DMI is directly related to milk yield and strategies have been developed to maximize intake in order to increase milk production, this shows its importance by the fact of an increase of about 1 kg on milk production at peak of lactation reflects about 200 kg of extra milk on the current lactation. Providing quality feed and maximizing DMI during the transition period is of high importance in minimizing NEB and its detrimental effects consequently improving milk production. Metabolic demands are increased to support lactation, and homeorhetic adaptations occur to partition nutrients to the mammary gland. A good example it is the glucose metabolism, an important metabolite used as main fuel for cells and also transformed in lactose by the mammary gland, which is affected in order of trying to meet th...
This paper focuses on the benefits of stem cell research in the medical and nursing field. New technology is always being created to help us understand the way the human body works, as well as ways to help us improve diseased states in the body. Our bodies have the ability to proliferate or regrow cells when damage is done to the cells. Take for example the skin, when an abrasion or puncture to the skin causes loss of our skin cells, the body has its own way of causing those cells to regrow. The liver, bone marrow, heart, brain, and muscle all have cells that are capable of differentiating into cells of that same type. These are called stem cells, and are a new medical tool that is helping regrow vital organs in our body to help us survive. Stem cells can come from adult cells, or the blastocyst of the embryo. The cells that come from these are undifferentiated, and can be specialized into certain cell types, making them available for many damaged tissues in the body. While using stem cells in the body is a main use, they are also being used to help doctors understand how disease processes start. By culturing these cells in the lab and watching them develop into muscles, nerve cells, or other tissues, researchers are able to see how diseases affect these cells and possibly discover ways to correct these diseases. While researchers have come very far in using stem cells, there are still many controversies to overcome when using these cells.
- In a normal blood sample, there should be a range of hemoglobin, RBC, MCV, WBC, and platelets. Hemoglobin’s function is to carry oxygen from the respiratory organs to the rest of the body. RBC’s function is to remove carbon dioxide from the body. MCV’s just refer to the average volume of red blood cells, which remove carbon dioxide. WBCs are extremely important for the body. They protect the body from infections, diseases, and foreign invaders. Platelets are also important to the body and their function is to prevent bleeding.
As the scientific field of Neuroscience develops and expands, so too does the discipline of Neuroethics. This new and emerging area of study aims to discuss the ethical applications of advancements in neuroscience. Over the past few decades, technological advancements in neuroscience have risen sharply. Every day, scientist’s understanding of the human mind increases exponentially. New technologies grant researchers the ability to make cognitive enhancements, carry out brain imaging and provide the human brain with a variety of different services. Neuroethics attempts to bridge the capabilities of science, with the social and ethical climate of today’s world. New advancements in what scientists can do, such as Brain Imaging, Cognitive enhancement, pharmacological enhancement of mood, and brain machine interfaces and non-pharmacological enhancement must be carefully examined to determine their proper and ethical usage.
What drives me to pursue a career as a biomedical engineer is not only to help disabled patients, but also my love of the field itself. Biomedical engineering combines two subjects that have left strong impressions on me, biology and physics. Just learning these subjects from classes and textbooks does not suffice to quench my curiosity. I want to learn more through personal experience. At SIMR, I will be able to handle my own research project, and it will really help me gain an even stronger interest, and propel me forward into my career
The cell is the basic unit of life. All organisms are made up of cells (or in some cases, a single cell). Most cells are very small; most are invisible without using a microscope. Cells are covered by a cell membrane and come in many different shapes. The contents of a cell are called the protoplasm.
Whenever you eat a meal, your body is working to break down the nutrients you have eaten. It then becomes energy that your body will need. This process is called metabolism. Metabolism is an important for all living things. Without it, we would not be able to break down our food into energy. No energy means not being able to keep a balanced lifestyle, and not having a balanced lifestyle can lead to illness and diseases that can affect our lives.
My passion for a career in Clinical laboratory science stems from a key experience with a li-censed Clinical laboratory scientist. On one day in the church , I was in dire need of help finding a job that can help me study medical in the future. For the first time I encountered professional-ism, knowledge, and humanity all at once. And this wasn’t a one-off experience. Each time I re-turned to the church, the exact same thing occurred: The Clinical laboratory scientist never seized to take the opportunity to encourage and help me knows better about the great work of Clinical laboratory scientists. From that moment, I decided to do my master in that field.
The history of anatomy and physiology dates back to ancient Egyptian times when humans were mummified after death and bodies would be stripped of their internal organs during the embalming process. It was not until much later when Hippocrates II, known as the father of medicine, was the first to write about human anatomy. Shortly after that, the Alexandrian Medical School was established, where human dissection was allowed for the first time, which promoted research and new discoveries in the field. From there, many other influential researchers came up with theories regarding the cardiovascular and nervous systems, etc; however, the missing links in some of the earlier theories was found with the discovery of the microscope, which changed the focus of research and led to many advancements in the field.
Many people don't know what biomedical engineers do. A biomedical engineer’s job is actually quite interesting. They analyze and create solutions to improving the quality and effectiveness of patient care. They also design technology to accommodate the needs of people with disabilities. They have a big role in helping people begin new lives. The main job of a biomedical engineer is to help create prosthetic limbs or organs for those who are in need of one.
