...“Biology Article” Yolanda Haskins Professor Lynn Roginsky Introduction to Biology May 9, 2013 A New System for Cancer Detection This article summarizes a new technique that would allow for cancer cell detection without being invasive to a person’s body. It states that currently, human cancer cell detection is conducted through a person being cut on or biopsied. This new procedure allows for humans bodily fluids to be utilized in detecting cancer cells. P.Chandra states, “While current cancer-diagnosis methods rely on an invasive biopsy” to relay that many may not feel the need or desire to undergo biopsy, a type of simplistic surgery, for cancer cell detection. This article relates to this course by the basic information I learned about the plasma membrane known as cell membranes. Cell membranes are lipid bilayers that consist mainly of phospholipids. However, when it comes to cancer cell membranes they tend to have more anionic lipids than normal cells. Our course text in Chapter 3 talks about the “Cell Structure” and gives us the break down on “What, Exactly is a cell? The Structure of Cell Membranes, Introduction of Prokaryotic Cells, etc.”. This article does not provide enough background information to help me understand this article. In my opinion, I would have like to read more about the differences between the normal cells and cancer cell membranes and how they are made up. This article caught my attention due to my family member surviving stage four...

...breast cancer is better than more screening. They found that women who are tested before the age of 45 have a greater risk of a false positive which results in having to deal with multiple tests and examinations without the need of them. Researchers suggest that women should wait until they are at least 45 to begin getting any mammograms done. The CNN article “New breast cancer guidelines: screen later, less often”, was written according to the research in the original source, “Breast Cancer Screening for Women at Average Risk”. The way that this information is given by researchers is commonly...

...February 18, 2011 Literature Review The article, Ovarian Cancer Listen for the Disease, was published in the November issue of the nursing journal Nursing2010. This specific article was written by Karen Blewitt, BSN, RN, AOCN. Ms. Blewitt is currently still in the nursing field and writes for the journal in her spare time. I selected this article about cancer due to my interest in the field of oncology. Just this past week, I went to the oncology office and learned a significant amount about several types of cancers and various forms of treatment. Cancer comes in all different types and forms, which is why it is so hard to fully cure. This article presents a case in which a woman in her early 50’s visits her doctor complaining of abdominal pain, urinary frequency, pressure in her lower abdomen, and an increase in her waistline despite efforts to lose weight. She is then stunned to find out that she has a mass in her pelvis which is later confirmed as Ovarian Cancer. This articled refers to Ovarian cancer as the “silent cancer” or the “disease that whispers” because early signs and symptoms are often subtle and can be confused with another diagnosis. The article then goes on to discuss the possible treatments such as surgical removal, chemotherapy, and radiation which is similar to all cancers. Ovarian cancer is not normally found early and normally has a poor prognosis. Many believe that a routine Pap Smear would detect the disease, however this is not true. Only an in-depth...

...” the first thought that pops into my head is, “wait, how much do I really know about genetics?” According to an article by Katherine Harmon a debated issue on selling an over the counter genetic test is one of great concern. When I began reading this article all I could really think was, “wow, what if I bought the test (being as curious as I am) and did it wrong?” In absolutely no way do I think I am close to being qualified to give myself this test nor understand the results. Genetics is of great importance and a serious way of finding out if a possible diseases lay within our future yet at the same time it’s not the easiest subject to learn. Since genetics test could possibly play a big role in finding our vital information, I stopped to think, “Could there possibly be limitations?” Now having read more on this interesting subject before fully making a decision, the National Cancer Institute explains the boundaries of what can be known from a positive or negative test. “A positive result generally indicates that a person has inherited a known harmful mutation, for example, BRCA 1 or BRCA 2, and therefore, has an increased risk of developing certain cancers…however a positive test result provides information only about a person’s risk of developing cancer. It cannot tell whether an individual will actually develop cancer or when.” After reading this interesting fact buying an over the counter kit or test would be pretty useless. Yes, it could tell whether I inherited the bad...

...palliative radiotherapy for lung cancer.” Palliative Medicine, 25(7), 675-681. This is a very interesting article written by A. Cox. The article states how e-technology dramatically increased new ways to obtain the patient’s symptom information, which was self-reported. They conducted study to provide lung cancer patients post palliative radiotherapy. There were 17 clinicians identified as patients who met the criteria, but there was only one clinician that gave approval for the patients. The physicians were very positive about palliative care. The study proved that these groups of patients were too old. The article stated that “to encourage acceptance of e-technology within palliative care, emphasis is needed on actively promoting the contribution of technology outcomes and the patient experience (Cox, 2011). I learned some good information on cancer technology. I would recommend this article to anyone wanting to read about cancer technology with patient services.

...“What if people really did that - sent their love through the mail to get rid of it? What would it be that they sent? A box of chocolates with centers like the yolks of turkey eggs. A mud doll with hollow eye sockets. A heap of roses slightly more fragrant than rotten. A package wrapped in bloody newspaper that nobody would want to open,” wrote Alice Munro in her story The Love of a Good Woman. (Good Reads, 2013) History: Alice Munro was a fascinating author born and raised in a heavily dominate Scottish-Irish community of Wingham, Ontario, Canada. Born on July 10, 1931, she was the eldest of three children and she still resides very close to where she was born and raised. She had a true passion for where her home was and where she felt comfortable. She focused her work on fictional writings. Although she spent her years as a writer, she rarely referred to herself as an author the way her husband did and joked when people referred to her as an author. She thought of herself as just a writer. Alice Munro was a compelling author whose work has landed her numerous awards in several countries and even turned down chances of winning more awards. Influences: Alice Munro had many inspirations to include Updike, Cheever, Joyce Carol Oates, Peter Taylor, and William Maxwell. She is often compared to Chekhov, referring to Cynthia Ozick, when it comes to writing style. She fed off of her inspirations to become the author she is today. Cynthia Ozick called her in a vaulting comparison...

...Week 3 Intro to Hospitality Management I read an article on in regard to eating meat “MEAT’S IMPACT” https://www.cspinet.org/nah/pdfs/meatsimpact.pdf And found that the article can potentially impact the restaurant industry if every person that frequents restaurants reads the article, and makes a conscious decision to better their health. The chance of this is likely less than a 2% chance, but if people as a group decide that they wish to benefit from changing their eating habits based on this article then it is likely that there will be a great reduction in the amount of meat that is consumed on a regular basis. The article indicates that there are many adverse effects that occur from the consumption of meat, anywhere from heart attack, cardiovascular disease to stroke, and colon cancer. So in most cases people will initially swear off the meat, but then remember meat is tasty. As with any food that is good to the palette, it is a double edged sword that shows us the product is very desirable, but we just need to remember that moderation is important to maintain a diet that will not end our lives in one way, or another. The article also mention other incentives to reduce the intake of meat such as, the amount of water it takes to produce the product, and the emissions of greenhouse gas caused from the production as well. Now, the last thing people are thinking when they are viewing a menu are things like how much water is required for this...

...Group 6: HPV as a leading cause of Cancer Human papillomavirus (HPV) was founded in the 1950s as a virus infection that is associated to many cancers. It is primarily transmitted through sexual contact and less intimate skin-to-skin contact. Preventions have been implemented to raise awareness of the virus. The first vaccine for HPV approved as a widespread use in the US was in 2006. The virus acts to infect the keratinocytes in the skin and mucosal membrane. Other areas the HPV acts as a carcinogen are the cervix, anus, penis, vulva, vagina, oropharynx, benign genital and cutaneous warts, respiratory papillomatosis, and nasal or oral papilloma. Some researchers have concluded that the HPV infection which is more common during the active period of age is directly related to certain cancers. Researchers have found that HPV is associated with certain types of cancers and also have found that HPV can have no association with certain cancers. The research we did will explain the various cancers associated with HPV and attempt to answer the question “is HPV the leading cause of cancer?” In the United Stated and around the world, cancer is and continues to be a very serious disease that affects millions of people. Head and neck cancers are “the sixth most common cancer in the world” (Lajer et al. 2012). While the link between HPV and cervical cancer has been established; it is still unclear to researchers how HPV is related to head and neck cancer. The authors assert that alcohol...

...stories 13-15. Two of these three stories involve health risk and one story pertains to a pro-life argument. The first story I read explained how the nuclear power industry is immune from liability in nuclear accidents. The example used in the article was the 2011 TEPCO Fukushima meltdown. Big corporations commonly go outside the US borders to build their factories or power plants due to two reasons. One much cheaper labor force abroad. Big corporations stand to gain a greater profit if they get close to the same quality of work while paying half the price, sometimes less than what a corporation would pay american workers. Another reason is countries abroad tend to have less strict regulations in certain areas of corporate interest, an example would be the TEPCO. Even though this power plant is host to native Japanese companies, I’m willing to bet General electric has some kind of financial stake invested with Toshiba and Hitachi. Several years after the meltdown there is still radiation present in Fukushima. The Japanese Fisheries research agency conducted a study and found that radiation levels in sea life south of the plant to be 124 times more than the threshold considered safe for human consumption. TEPCO has released inaccurate reports on the actual damage assessed and have released few details to the press to avoid further scrutiny. The real interesting thing about this example is that General Electric owned 5 out of the 6 reactors in the TEPCO plant and 3 of those reactors...

...to its multiple health benefits. From keeping your blood sugar levels in control to improving your sexual stamina, this vegetable is a well know antidote for anaemia in many Indian households. In addition to acting as a natural food colour, it can be consumed in the form of salad, juice or halwa. And above all, there are 11 reasons why you should include beetroot into your diet. #1 Lowers your blood pressure levels Beetroot is a great source of nitrates, which when consumed, is converted to nitrites and a gas called nitric oxides. Both these components help to widen the arteries and lower blood pressure. Researchers also found that having just about 500 grams of beetroot every day reduces a person’s blood pressure in about six hours.(1) Read simple tips to include beetroot in your diet. #2 Reduces ‘bad’ cholesterol and prevent plaque formation Beetroot is known to contain large amounts of soluble fibres, flavanoids and betacyanin. Betacyanin is the compound that gives beetroot its purplish-red colour and is also a powerful antioxidant. (1) It helps reduce the oxidation of LDL cholesterol and does not allow it to deposit on the walls of the artery. This protects the heart from potential heart attacks and stroke reducing the need for medication. #3 Good for pregnant women and unborn child Another amazing quality of the root is that it has an abundant supply of folic acid. Folic acid is important for pregnant mums and unborn babies because it is an essential component for the...

...an act lead to a more effective health care system or are these numerous screenings essential to saving lives? Considering that I hope to be a physician assistant in the future, I felt that this issue was something I should investigate since one day, I will be the one ordering tests for patients. In order to determine which route is the correct one to take, I read two opposing articles discussing the topic. In his article, “PSA Testing Controversy Reignites ‘Over-Screening’ Debate,” published on PBS.org, journalist Jason Kane begins with a story about Denham Kelsey, a man who would never had known he was developing prostate cancer if it was not for his routine screenings. When the U.S Preventive Services Task Force released news that it was no longer going to require regular PSA Testing (prostate-specific antigen test), a heated battle reignited. Kane claims that people would not get the routine tests if they are not considered necessary or are not covered by insurance. He argues that preventative measures like PSA screenings do help prevent some diseases because early diagnosis is key. In H. Gilbert Welch’s article, “If You Feel O.K., Maybe You Are OK,’ the professor of medicine at the Dartmouth Institute for Health Policy forcefully states that over diagnosis and overtreatment is a major problem in the healthcare system. He argues that the process makes people mentally sick, causing them to overthink symptoms and notes that people are automatically turned into patients...

The main message of the TIME Health article titled Can Carb Cycling Help You Lose Weight? written by Cynthia Sass published on April 6th 2017 is that although carb cycling can prove effective in many body builders or athletes, carb matching is proven more effective in the average person. Carbohydrate (carb) cycling is the process of limiting carbohydrates in the diet on a set schedule, alternating high and low carb days; where carb matching is more or less matching high/low carb diet days in accordance with the amount of activity or energy needed for the day. The article highlights some benefits to carb cycling such as: increased muscle mass, decrease body fat, and...

...The Clocks Within Us Analysis According to the article published in the February 2015 edition of the Scientific American, genes in the brain, liver, pancreas, and other tissues help keep the various parts of the body in sync. These ideas are portrayed throughout the article written by Keith C. Summa and Fred W. Turek, “The Clocks Within Us.” The article is based around circadian rhythms, which describes how the body works around 24-hour cycles. Both authors are extremely validated when it comes to informing the public on circadian rhythms. Summa is a PhD at the Northwestern University Feinberg School of Medicine and is interested in understanding how to apply research findings to clinical medicine. Turek is a neurobiologist and director of the Center for Sleep and Circadian Biology at Northwestern. He is also the founding president of the Society for Research on Biological Rhythms. Learning more about the different clocks in the body can help explain bodily disruptions caused by out of sync cellular clocks. Circadian rhythms are important in the world of biology because of their effects on one’s health. When all the clocks in our body are not in sync, we can experience diabetes, depression, obesity, and more. The clocks could fall out of sync when sleep and eating patterns falter. This information could have been presented in the Scientific American, a popular magazine that is read by many people across the nation, because many people change their daily patterns. For example...

...The author–date (Harvard) style This chapter explains some of the more common applications of the author–date (Harvard) style of referencing. It is based on the Style manual for authors, editors and printers, 6th edn, 2002, pp. 188–208 and pp. 220–32. You should always check your unit guide and/or with academic staff (unit chair, lecturer or tutor) to make sure that this is the recommended style for your unit. Note that some units, courses and disciplines use variations of the style described here. You must reference all material you use from all sources and acknowledge your sources in the body of your paper each time you use a fact, a conclusion, an idea or a finding from someone’s work. This establishes the authority of your work and acknowledges the researchers and writers you have drawn upon in your paper. It is necessary to cite your sources each time you: • reproduce an author’s exact words (quote); that is, copy word for word directly from a text. Page numbers must be included in the in-text citation when quoting directly. • use your own wording (summarise or paraphrase) to explain or discuss what someone has said. Page numbers should be provided if the summarised or paraphrased material appears in specific pages or sections of a work. If you copy an entire table, chart, diagram or graph or if you take only some of the data contained in such sources, you must provide a reference. Sources such as journals, books, encyclopedias, computer programs and software, information...
