• use knowledge of biological principles to ask relevant questions about the natural world
• make observations and discriminate between scientific and pseudoscientific explanations 1. Select one of the following topics below.
2. Find articles related to the topic. 3. Write two pages, double spaced, excluding references. You must read the articles that you find and summarize the information they contain briefly in your own words. Extensive quotes from the article are discouraged. This assignment demonstrates the acceptable, ethical, and academic method for citing information from a public source. You may not use online encyclopedias as a source more than once. Use APA style for citing references (see

You will be expected to write a paper with proper formatting, spelling, and grammar. Topics (select one)

a) Genetically modified food. What is the purpose of human-made genetic recombinations in food? Are foods that contain genes resulting from artificial genetic recombinations really safe? What foods in your supermarket result from genetic recombination? What types of regulations exist for these foods? (For example, you might search the Food and Drug Administration website.) Clearly explain your reasoning for each answer.

b) Stem cells. A relative of a friend of yours had a spinal cord injury after a bad car accident. The medical team has decided that this patient is a good candidate for a clinical trial using stem cell therapy. Your friend has not had a biology course since high school, so you are going to write for him or her a two-page discussion of stem cell information. In your discussion, include a description of the biology of stem cells, and explain how these cells are unique in their ability to treat diseases and injury. The following website from NIH regarding stem cell research will be very helpful:

    Due to recent discoveries, stem cell research will have many future medical possibilities. A recent stem cell breakthrough shows that cloning human organs or body parts to treat patients with injured organs or limb deficiencies could be possible. “The cloning techniques can also be used to grow organs for patients with a failing liver or kidney.” Because the newly cloned organ will be genetically identical to the one being replaced, rather than a donated one, the chances of it being rejected will be very low. Ultimately, this opens up many possibilities of curing patients with injuries, amputations, and failing organs. Stem cell research also reveals the ability to cure diseases. “Researcher Dieter Egli said their work was inspired by the thought of being able to take stem cells from embryos and use them to treat and even cure diseases. Worn out hearts could be patched up, aged brains could be rejuvenated and diabetics could be freed from the need to take insulin, all thanks to stem cells.” Stem cell researchers believe it is possible to cure diseases by replacing old organs with newly cloned ones. This will impact future medical possibilities because newer treatments will be out there and the ability to cure diseases such as heart disease, diabetes and cancer may be possible. Furthermore, federal funding for stem cell research has been limited although by the popularity of its breakthroughs; stem cell research may receive federal funding in the near future. This will broaden stem cell research and allow scientists a greater chance of discovering new medical possibilities in the near…

    Stem cell transplants are often one of the last choices a patient has to survive cancer. All have already gone through chemotherapy, radiation therapy or both and this is the next step in their treatment. Patients have two choices in transplants autologous or allogeneic. In an autologous transplant stem cells are collected from the patient and then given back to them at a later date after the body has been properly prepared for transplantation. In an allogeneic transplant stem cells are collected from a donor, related or unrelated to the patient, then transplanted into the patient. Stem cells can be collected in two different ways. One way is via bone marrow and the other is via peripheral blood. The donor’s or patient’s bone marrow is collected from the pelvis, femur or sternum, though the pelvis is the most common, and then infused into the patient via a central line. In a peripheral blood stem cell collection the donor or the patient has their stem cells collected via a central line in a process called apheresis. This can take multiple collections to ensure enough stem cells for transplantation. Both procedures need to be meticulously planned and all support medications given to ensure successful collection.…

    Spinal cord injury (SCI) is a traumatic and devastating event in any person’s life (Chen, 2013). Spinal cord injury might be partial or total, but whichever type can cause impairment of physical mobility leaving those affected with challenges of coping with rehabilitation. However, current treatment continues to focus in the provision of care in the acute stage and the prevention and (Chen, 2013) treatment of complications (Chen, 2013). SCI continues to impact the lives of those affected and their families socially, physically, mentally, and spiritually. Independence to the greatest ability of the patient is a long-term goal. By providing a multi-disciplinary team to treat a patient, it gives additional professional support to allow a more rounded, stronger, and more positive recovery. Although many scientists are studying nerve regeneration and conducting stem cell research (Chen, 2013) for the treatment of SCI but the cure is still a long way off (Chen, 2013). However, self-perception, age, self-efficacy are factors influencing individuals with SCI to successfully moving forward without withdrawing from the society. Patients who effectively learn to…

    Nevertheless Spinal Cord injuries will be able to be treated as a result of using stem cells which can regrow the damaged spinal cord. Also there will not be any need for organ transplant because the stem cell can allow the regrowth of a person’s organ lost either through an accident, tissue damage or disease. This will make it easier for the receiver as the organ will come from their own DNA and therefore there will not be any risk of organ.…

    A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation. Scientists believe this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Results of clinical trials into double cord blood transplants (in place of bone marrow transplants) have shown the technique to be…

    Stem cells, often called the building blocks of the human body, are positioned within the body’s blood, tissues, organs, and immune system. Once they are transplanted, they have the capability to either reconstruct or restore a patient’s damaged cells which could enhance the patient’s health; and in some cases can conclusively save a person’s life.…

    If you’ve already found a donor, you will coordinate the proper transplant. There are many steps to getting the proper transplant. The first step is to make an observation of the patient and donor to make sure that they can both tolerate the process. …to make sure everything is okay with both people. If both are okay, then the process leads to the day of the transplant. One day before the transplant, the recipient of the transplant is going to receive chemotherapy or radiation in combination to eliminate their own bone marrow to treat the illness and create space for the transplant. During this time, the donor will receive the bone marrow stimulant, and after 4-5 days, they can proceed with the process of apheresis. The day of the transplant, the patient has already finished all chemotherapy and is only waiting for the donor’s cells. The recipient is going to receive this as a blood transfusion. It’s very simple, it doesn’t require surgery, it doesn’t require any other procedure, and it is basically just a stem cell transfusion from the…

    SCI is an unexpected and devastating disease, which is caused by direct mechanical damage to the spinal cord and usually leads to motor and sensory dysfunction subject to the condition of injury. SCI is one of the major causes of death and disability in clinical situations. SCI brings enormous psychological and economic burdens to individual family as well as the whole society as a whole. (1,2,3,4,5) In the United States there are approximately 282,000 people suffering from SCI and an average growth of 17,000 cases annually. (6) Spinal cord injury includes primary physical injury in addition to secondary injury. The pathogenesis of SCI after the primary trauma plays an important role in an initial tissue disruption, and then following that, the initiation of secondary cellular processes beyond the injury site can lead to long-term spinal deficits and disabilities. (7) The mechanisms involved in the cell death during SCI are complex, encompassing inflammation together with excitotoxic neurological damage. Inflammation is one of the important…

    As of May 18 2001, scientists have grown blood cells, blood vessel cells, bone cartilage, neurons, and skeletal muscle in petri dishes and continue to grow many other types of cells. This is encouraging news because a lot of diseases involve the death or dysfunction of a single type of cell. Scientists believe that the introduction of healthy cells into a patient will restore lost function. Since researchers have discovered how to isolate and culture stem cells, they have to figure out how to coax these cells into becoming the specialized cells and tissues that they need for transplant into patients. Discovering this process could lead to better means of preventing and treating birth defects and cancer. Also, it would produce an almost endless supply of human cells and tissues in the laboratory to test experimental drugs on.…
