...I believe that nuclear medicine harms life. The way nuclear medicine works by the patient receiving a radioactive material to take, and then, the doctors are able to study the organ system or look into deeper body parts for a short time through the energy form of gamma rays. Even though this method allows the doctors to examine the patient more closely than normal a normal X-Ray, there are more risk in dealing with nuclear items. 1) When using nuclear medicine, the patience will receive a certain amount of ionizing radiation depending on the type of nuclear medicine. Putting radiation in context, a thyroid scan gives a dose of 0.14 mSv, lung scan is 2 mSv, bone scan is 4.2 mSv, a CT scan is 8 mSv, and the worst is Cancer treatment, which gives...

...Running head: NUCLEAR MEDICINE 1 Concepts of Nuclear Medicine NUCLEAR MEDICINE 2 Concepts of Nuclear Medicine * What type of radiation is typically exploited in most nuclear medicine procedures? Nuclear Medicine is a specialty used to diagnose and treat diseases in a painless and safe manner, which uses a pharmaceutical (medicine) that’s attached to a small amount of radioactive material (a radioisotope). The procedures can often identify disease in an early stage, thus allowing for treatment to be started sooner. The most common of nuclear enhanced medical procedures involve the use of x-rays — a type of radiation that can pass through our skin. X-rays and other forms of radiation also have a variety of therapeutic uses. When used in this way, they’re intended to kill cancerous tissue, reduce the size of a tumor, or reduce pain ("Medicinal Radiocompounds). * How are patients prepared for nuclear medicine procedures? For a nuclear medicine exam, the patient is given a small amount of radioisotope, either orally or by injection, to enhance the visualization of selected organs or vascular structures. * What are the advantages and limitations of nuclear medicine? Advantages Nuclear medicine is a tool for physicians and scientists to diagnose several diseases. Nuclear Medicine is already being used as the most effective treatment for many cancerous diseases and conditions. X-rays used in nuclear medicine can scan the most sensitive...

...Courtney Meade is an x-ray technologist at Tennova North Hospital in Knoxville, TN. I asked her a series of question on November 20, 2015.Courtney is credential to work in AART (B), CNMT, x-ray, CT scans, and nuclear medicine She always knew she wanted to be in the medical field but wasn’t exactly sure what degree she would to pursue. It wasn’t until Courtney was in a car accident when she was sixteen years old that she knew she wanted to pursue a career in x-ray technology. This decision could be made, because it is really amazing to see what x-rays actually look like, to learn what they are, and how they work. Sometimes it’s hard for even college students to figure out what they want to major in, to hear her say she knew at sixteen what...

...Cloning is not new and experiments with frogs and toads date back to the 1970s . Experiments involving plants and animal embryos have been performed for years, yet experiments involving human beings have never been tried or thought possible, until "Dolly". Her birth shocked the scientific community and has spurred discussion about the possibility of human clones. In the following essay I am going to speak about the subject of Human Cloning, its pros and cons, and speak against the following issues. Pros of Human Cloning Prior to arguing against the human cloning it is imperative to note the positives of this genetic technology. Human cloning will allow doctors to determine the cause of spontaneous abortions, give oncologists an understanding of the rapid cell growth of cancer, allow the use of stem cells to regenerate nerve tissues, and advance work on aging, genetics, and medicines. Some people argue that cloning is the logical next step in reproductive technology. Identical twins are natural clones, so reproductive cloning can be regarded as a technological version of a natural process (McGee, 82). If a couple are infertile, why shouldn't they be able to produce clones of themselves? If a couple have lost a child, why shouldn't they be able to replace that loved individual with a clone if that is possible? Equally if someone has made a great contribution to science, music, the arts or literature, it seems like a good idea to produce more of them in the hope that we might...

...higher yield, improve the nutritional value and improve taste of food. Genetic engineering also called biotechnology will also improve shelf life to fruits and vegetables. I do not consider this to be as big of an issue as a lot of people are making it. Obviously there are reasons that the government does not have to tell us when we are eating genetically engineered food or not. It is because it is completely safe, and I believe that the people that are against it simply do not know enough about it. I will admit that when I first heard about “cloning food” I was a little disgusted as I also did not understand it at that time. There are some dangers that come with genetically engineered foods. Many of the opposed claim it causes nuclear pollution, global warming, and the toxic effects of pesticides and herbicides. Most of these crops developed are resistant to herbicides. Therefore this will result in greater pollution to our food and water with toxic agrochemicals. Many of the opposed also question ethical concerns due to the transferring of animal genes into plant genes. Vegetarians and religious groups would find this process unacceptable. Foods have been genetically modified for many years. This process is called selective breeding;...

...TITLE: ANTIBIOTICS : ARE THEY REALLY MAGIC BULLETS? The human body is exposed to substances that have the potential to cause harm on a daily basis. The body protects itself against these substances in several ways. Our natural defences give the body an opportunity to fight off invading microbes that may cause disease. The first line of defence is non-specific and aims to stop microbes from entering the body. The skin and mucous membranes act as a physical barrier preventing penetration by more harmful microbes which could lead to infection (1). The normal body flora on the surfaces of the body, reduce the area available for pathogens to attach to, as well as acting as a competitor for suitable nutrients. The body also produces several antimicrobial substances that kill or break down bacteria. A specific example of a physical barrier is when the blood produces a clot to seal the wound to prevent microbes from entering when the skin has been cut. The second line of defence is also non-specific and involves the process of phagocytosis. A type of white blood cell, called phagocytes, send out pseudopodia to attack the pathogens. Digestive enzymes are then released which break down the harmful microbes (1). Conversely, specific immunity is when resistance is given to a particular foreign agent such as a virus or bacteria, known as antigens. These antigens work to attack the pathogen by causing specific cells to replicate and produce proteins to provide protection...

...19 CASE The Case for Open Heart Surgery at Cabarrus Memorial Hospital Situation It was a clear, crisp October morning in Concord, North Carolina. The board of trustees of Cabarrus Memorial Hospital gathered in the windowless, walnut paneled boardroom for its monthly meet- ing (see Exhibit 19/1 for board members). Board chairman George Batte opened the meeting saying, “Because we do not have an open heart surgery program, patients needing open heart surgery or coronary angioplasty have to be transferred to another hospi- tal, causing inconvenience to the patient’s families and risks from delayed treatment. There are several questions we have to answer in addressing this issue. Should we add open heart surgery to the mix of cardiac services we offer? Does the hospital’s existing service area provide adequate patient volumes to support the program? What This case was written by Fred H. Campbell, The University of North Carolina at Charlotte, and Darise D. Caldwell, Executive Vice President and Chief Operating Officer, Northeast Medical Center.

...Research paper on Stem Cell Research Legislation and the related legal issues: What is the history of Stem Cell Research Legislation in the United States? How does it compare to comparable statutes in the rest of the world? In this paper talk about what the current legislative state of affairs is and where the law on stem cells in the United States should go in the future and why. Make sure you use ample research and cited sources to support your arguments but make sure to state your own opinion on the issues as well. Stem Cell Research TJ AS OF: 2/4/2009--Introduced. Stem Cell Research Improvement Act of 2009 - Amends the Public Health Service Act to require the Secretary of Health and Human Services to conduct and support research that utilizes human embryonic stem cells, regardless of the date on which the stem cells were derived from a human embryo. Limits such research to stem cells that meet the following requirements: (1) the stem cells were derived from human embryos donated from in vitro fertilization clinics, were created for the purposes of fertility treatment, and were in excess of the needs of the individuals seeking such treatment; (2) prior to donation, it was determined that the embryos would never be implanted in a woman and would otherwise be discarded; and (3) the individuals seeking fertility treatment donated the embryos with written informed consent and received no financial or other inducements.

...“atomically precise engineering” which could have a positive impact on every one of us. Picture what we could do when we have carbon nanotubes (rolled up sheets or graphite that are 1000 times thinner than air) that are 100 times stronger than steel yet six times lighter. Nanotechnology may seem very futuristic, however it is not something that is new to us. We have already built many machines/materials that use nanoparticles (particles with a range of 1nm to 100nm), some of which include self-cleaning glass, swimming pool disinfectants, scratch resistant coatings and safer yet more effective lithium ion batteries. Now we are looking into using these nanoparticles for more serious issues, for example in curing cancer and developing more effective nuclear weapons. But is this something that we should worry about? Much of nanoscience and many nanotechnologies are concerned with producing new or enhanced materials. The reason most nanotechnology researchers are so excited is mainly because they can reinforce materials to make them not only stronger, but also lighter. The products that we can get from this will have new electronic, optical and mechanical properties. One...

...Three programs stood out to me as I did research, and those three are VetOfficeSuite.com, eVetPractice.com, and ezyVet.com. As you read through this paper, I will explain the pro and cons of each different software package. VetOfficeSuite.com was founded in March, 2010, by Eric Bregman, VMD. Eric is the co-owner of the Bregman Veterinary Group, a growing group of Veterinary practices started by his father Dr. Jack Bregman, in Coney Island, NY in 1970. Eric, his dad Jack, and his brother Allan Bregman, DVM, now own 3 veterinary hospitals and a Nuclear Medicine facility in the New York City area, and recently have expanded to Orlando, Florida, where they will have 2 additional full service veterinary hospitals. eVetPractice.com began back in 2011 when our owner and founder, Eddie Heinz, was tasked by his sister-in-law to find an affordable practice management solution that offered the necessary features to run the new mobile practice she was beginning. Dr. Kristen Arp had worked in corporate medicine for some time and new the value of properly managing her business, but like most veterinarians, did not have a background in software and was concerned about making the right choice. Fortunately, she reached out to the family software developer for assistance. ezyVet was founded in 2006 out of the desire for an intuitive, affordable and customisable software that could cater to Veterinary Practices of all sizes and compositions. Plenty of other software options existed but none seemed...

...Print Media Vs Electronic Media We are living in a rapidly developing and modernized era where technology is taking charge in every walks of our life. This technology may come with many advantages and disadvantages as well. Every development is due to rapid modernization, improvement of old administration methods and the use of new technology to make things even better. However with the growing modernization human demand for knowledge is also increasing. Media serves an important role in keeping people informed about the events and innovations around the globe. This information may reach us in two forms, either through print media which is the oldest method, or the other one can be electronic media. With the improvement of electronic media during past few years and daily reports on achievements, electronic media has dominated over print media during past few years. Print media is the oldest form of Mass Media, and still not outdated. Daily about 70% of people start their day by reading newspaper, which is the oldest media around the world. Newspaper gives us information about whole world within few minutes of reading session, with a choice to skip the topics that we are not really interested about. Print Media still forms an important part of Media Industry which has been given a competition by electronic media and a new technology called e-newspaper applications. But still newspaper holds its value even today and is competing strongly with technology backed media. Basically...

...as important as the benefits and complications as well as the ethical and legal ramifications of it, which are at the core of the modern day debate. In 1997, a sheep named Dolly gained national recognition. Dr. Ian Wilmut, a Scottish scientist from the Roslin Institute, introduced her to the world as a genetic copy of her mother. Animals, as humans, receive half of their DNA from their mother and half from their father. This creates a unique individual. It took scientists 277 tries to succeed in creating Dolly. While Dolly has the same DNA as her mother, they are different in many ways. Human twins share the same DNA but have different personalities due to life experiences. The process Dr. Wilmut used to create Dolly is called “nuclear transfer.” Scientists took udder cells from her mother and let the cells multiply until they divided many times. At this point they took an egg from a second ewe and removed the nucleus. One udder cell was placed next to the egg cell and they were joined using electricity. This egg cell now contained the DNA of the udder cell. This cell divided and developed into an embryo. The embryo was...
