Arguments on genetically modified foods

Arguments on genetically modified foods Introduction Genetically modified foods have become a major concern and have caused controversy regarding both their health and environmental effects (2). Using modern techniques of genetic engineering, it is possible to introduce specific genetic material derived from any species of plant, animal, or microorganism, or even a synthetic material, into different species of plant (Journal 1) This allows a desired trait to be enhanced and reproduced. (3) (4) The resulting plants are commonly known as genetically modified (GM) plants; when used as food sources, they are known as GM foods. (Journal 1) It is probable that crop improvement began as soon as farming did (1) It is thought that improvement to crops and harvesting developed subconsciously with farmers selectively breeding animals and isolating, to then reproduce crops from those with the most desired attributes and from highly variable populations.(1) The first genetically modified crop was the tomato Flavr Savr, produced by a Californian company Calgene, in 1992 whose intention was to create a vine-ripened tomato that was both long-lasting and tasty. (6) However the company failed to prevent the skin of the tomato from soften whilst the fruit ripened. It took 10 years for the development of the tomato, (6) but eventually it received FDA approval in 1994 (6), and led to an increase in GM food products available on the market. Romania, Mexico, Germany, Australia and France are just a few of the 13 countries known to have grown genetically engineered crops on their land for commercial use in the year 2000. (7) The United States of America produced 68% of the worlds GM crops, and therefore became the largest producer of these crops. In comparison to this, Argentina produced, 23%, Canada, 7% and China only 1%. Statistics from 2007 have shown a substantial increase from 1.7 million hectares being used for growing Gm foods in 1996, to 143 million hectares in 23 countries around the globe, with 90% of GM food produced being in developed or newly-developed countries.(journal one). Ways to make GM foods. Genetic modification of a particular plant or animal species can be accomplished by a number of different ways. (3) Genetic engineering involves the DNA alteration of a plant or animals DNA which holds the genetic information of the species. It is the alterations of a specific gene that enables modification of certain characteristics displayed. In order to change a certain characteristic, the corresponding gene coding for it, must initially be isolated in order to be inserted into a new DNA strand using a transfer vector. A Vector is an agent that can carry a DNA fragment into a host cell. (19) Plasmids are circular DNA molecules that are examples of vectors and can replicate independently of the host cell. (3) Once the gene is present in the transfer vector it can then be directed into the cells of the target organism. Then inside the cell the vector replicates and becomes part of the cells own DNA, altering the organisms characteristics. Similar to this method is the vector technique which involves the products being inserted directly into genome via another vector. As well as this there is also the biolistic method, which is commonly known as the gene-gun method and is a technique predominantly used in plant modification. (20) Pellets of metal coated with the desirable DNA are fired at the target cells which are then allowed to reproduce, and may possibly be cloned in order to produce a genetically identical crop. (20) Advantages and disadvantages of GM foods With the worlds population expected to reach 12 billion in the next 50 years, the demand for high quality produce will continue to increase. By growing genetically modified plants with a resistance to pests or herbicides, then the use of chemical applications may be reduced, as can the costs of producing a crop, damage by unwanted pests/weeds.(8) With the rise of various different virus, diseases and bacteria that effect and inhibit the growth of a crop, technologies have enabled genetically engineered crops to be resistant to these different diseases. (9)Plants such as tobacco and potato have had antifreeze genes introduced in to them, to encourage the plants to withstand cold temperatures that would normally kill such plants. (10) A common problem in third world countries is malnutrition with estimations of 1.02 billion people being undernourished and starved. (13) The main staple diet for these people is rice which unfortunately does not contain sufficient quantities of the nutrients and vitamins required to help prevent malnutrition. Genetically engineering this crop in order to create a nutritionally enriched rice variety would have the potential to help improve and in turn, eliminate these deficiencies. Vitamin A deficiency, estimated to affect millions of people around the world prompted the design of Golden rice researched by Ingo Potrykus and Peter Beyer and contained very large quantities of beta-carotene, which the body uses and coverts to Vitamin A, and is required for a number of different metabolic functions including in vision, immune functions and bone metabolism. (3) Genetic engineering techniques are now more commonly being used in order to introduce into plants, particular DNA that leads to the expression of distinct and unique proteins that are of specific interest and may be harvested and used in the production of pharmaceutical compounds. (11) Currently, synthesis of plant-derived proteins intended for pharmaceutical use is still in the early development stages. Examples of the types of protein and their intended use are summarised in the table below. Nutrition Some examples of GM plants with improved characteristics designed to improve health and nutrition are Maize with added vitamin C content, Potato with insulin as well as enhanced calcium levels, rice with added iron or zinc and coffee beans with decreased caffeine content. (journal 2) One study in to which a genetically modified green pepper and a standard unmodified pepper were analyzed for their nutrient and mineral contents and showed no significant opposing results between the two peppers. The analysis showed that there was neither significant difference in the energy and the protein levels nor a difference in the mineral content which included calcium, phosphorus, iron, sodium, potassium, magnesium, and zinc. This therefore concluded that, the nutrient composition of the genetically modified green pepper was found to be equivalent to that of the standard unmodified peppers. (journal 11) Another study that tested genetically modified Bt maize on laying quails also gave a similar conclusion to the green pepper study. (Flachowsky et al., 2005b; Halle et al., 2006).The results showed that Bt maize did not significantly influence health, hatchability and performances of quails nor did it affect the quality of meat and eggs of quails compared with the unmodified maize that was also tested. (journal 2) One exception to this study however was the that performed by Piva et al. (2001a,b) who noted that significantly improved animal performance was associated with a diet containing the Bt maize. It is thought that this improved performance demonstrated by the animals fed the genetically modified Bt maize crop, was because it reduced secondary fungal infection and, as a consequence, reduced mycotoxin contamination. (journal 2) Toxicity Publications on GM food toxicity are scarce. Although there are many arguments and opinions surrounding the toxicity of GM foods, there is little experimental data and analysis to construct such arguments. In fact, no peer-reviewed publications of clinical studies on the human health effects of GM food exist. Even animal studies are few and far between (18) Acute toxicity studies on the Flavr Savr genetically modified tomatoes, required by the FDA, were carried out with rats to determine toxic effects of the GM product. It was concluded that mean body and organ weights, weight gain, food consumption and clinical chemistry or blood parameters were not significantly different between GM-fed and control groups. However it was noted that sections of the stomach in up to 7 of the 20 female rats fed the GM tomato, showed mild/moderate erosive/necrotic lesions and as well as this 7 of the 40 rats involved in the experiment were known to have died a few weeks after for unstated reasons. (18) Another experiment that tested herbicide-resistant GM maize showed significant differences in fat and carbohydrate contents compared with non-GM maize. Toxicity tests were performed and showed that the rats ability to digest was decreased after eating GM corn. (18) Likewise tests in to potatoes transformed with a specific toxin gene or the toxin itself was shown to have caused an array of unwanted effects and showed that, CryI toxin was indeed stable in the gut of the mouse and therefore GM crops expressing it need to be subjected to thorough teststo avoid the risks before marketing. (18) Such studies support peoples concerns about GM foods and highlight the need for further research in to them and their health effects. Allergies Another issue with the rise in the production of genetically modified crops is the transfer of allergens in to new crops and the effects of particular allergens on human immune response. (journal 3) The majority of dietary proteins consumed are hydrolysed, and digested into smaller peptides that do not produce immune response in most people. However for those unfortunate enough to have hypersensitivity disorders, allergic type inflammatory responses can occur when contact with certain foods is made. For this reason, the introduction of genetically modified plants into the human food chain that contain allergens or proteins of unknown allergic potential could be of risk. (Journal 8) Nordlee et al. (1996) cited in (journal 8) demonstrated using the Brazil nut protein that allergenicity was indeed transferable by genetic modification. Amongst other things these studies confirmed concerns that sensitivity could be transferred to transgenic plants when an allergen is expressed in a non-na tive host through genetic modification. (journal 8) Lee et all (2006) compared the allergenicity of GM potatoes with that of non- GM potatoes in which 1886 patients who suffered various allergic diseases etc were used for testing. From his study he was able to conclude that genetic modification of crops did not cause an increase in allergenicity. The use of certain animal models has been developed in order to test whether or not food components such as GM proteins could potentially induce allergic reactions. (journal 2) The animals are often responders to high IgE and are sensitised before given the test compound. The animal models all have in common the production of specific IgE antibodies to the specific proteins. Particular proteins that cause food allergy in humans are claimed to produce more pronounced IgE responses whereas proteins that do not readily cause such effects in humans are claimed to induce poor IgE responses. (Journal 2) An example of one such model is the BN rat which is a high-immunoglobulin (particularly IgE) responder strain and is similar to humans in the way that they produce antigen-specific immunoglobins,-which are glycoproteins that function as certain antibodies. (3) Experimental investigations in to the hypersensitivity of rats to specific proteins performed by Knippels et al., 1998, showed the rats were capable of producing specific antibodies (IgG and IgE) and immune responses to the model antigen ovalbumin, found in egg white and often employed in experiments into immunology and hypersensitivity to stimulate allergic reactions. (3) Analysis of the research showed the rats developed allergic responses to the same problematic proteins that cause reactions in humans. (Knippels Penninks, 2002). (Journal 8) Pharmaceuticals One of the most impressive applications of genetic engineering is now the development of so-called pharma crops. Specific genes in some useful plants are modified with in order for certain chemicals, antibodies, hormones and proteins to be produced that can be used in different applications in the pharmaceutical industry. (14) The company, INB Biotechnologies in Philadelphia have been recently designing a nontoxic anthrax vaccine through the transgenic modification of petunias. This causes the production of new proteins by the plant that in turn causes the development of antibodies against the anthrax bacterium, when consumed. (16) Trials have begun on genetically engineered crops designed for healing wounds and treating conditions such as cystic fibrosis, cirrhosis of the liver and anaemia; antibodies to fight cancer and vaccines against rabies, cholera and foot-and-mouth disease. (15) The concept of genetically engineered crops for pharmaceutical use is a fairly new idea, and therefore such products are still in their preliminary stages of design and testing. However significant concern has been raised surrounding their use and possible consequences. For instance it is thought that food crops already are or may in the future, be contaminated by DNA sequences from GM crops. (15) Genetically modified crops run the risk of eventually introducing unknown, potentially harmful chemicals into the food chain, by accidental cross breeding and seed contamination. (17) Conclusion As well as there being many benefits to genetic engineering and the introduction of genetically modified foods, there are as well, possible dangers and hazards leading to concern over their use and potential risks to both the environment and to humans. However there is inconsiderable evidence to suggest that there are disadvantages and significant risks of consuming GM foods. Various testing has been conducted on an array of substances and components of GM crops to test for certain effects, some of these being toxicity and allergenicity. There are conflicting reports; some suggesting GM foods are safe, others that say they are dangerous and a risk to human health. Although only slight effects have been observed on the animals tested, it is enough to warrant anxiety over GM foods and their possible implications on humans. Some would argue minor changes and effects on animals doesnt necessarily mean that they would have the same effect, if consumed, on humans, yet, there have also been a number of experiments that contradict this and analysis of which conclude little or no clinical, toxicological abnormalities observed in the animals having been tested. It has been demonstrated that Genetic modification as well as being advantageous can also increase the nutritional value of a food source, providing useful benefits, such as crops with extra vitamins/minerals etc such as the example of golden rice highlighted above. However there are also significant disadvantages such as possible toxicity and allergic components in some GM food sources. Having looked at the evidence surrounding such factors it is difficult to say whether or not there are nutritional arguments against genetically modified foods. It is safe to say therefore, that new and improved methods are needed to further investigate the compositional, nutritional, toxicological and metabolic differences between GM and conventional crops likewise the techniques used in developing GM crops in order to expel the fears of many and allow for technology in this field to expand safely.

Diana in the Docks

Diana In the Dock : does privacy matter? ‘Diana' as used in the title is referring to the Former Princess of Wales ‘Princess Diana'. In November 1993 The mirror newspaper published photos of ‘princess Diana' while she was working out at a gym. These photo's were taken out of consent by Diana by the Gym owner Bryce Taylor who was paid over 100,000 pounds for the photos . Thus Princess Did had his assets frozen and sued him.Due to the fact Bryce Taylor was broke he seeded legal aid where he was provided with Geoffrey Robertson o defend him. Robertson describes this case through the use of a paradox in the opening paragraph â€Å"Diana had been the victim of a dirty trick which provided windfall profits to undeserving people† these undeserving people being ‘Bryce Taylor' and the mirror magazine. Donna's perspective is that her privacy was breached for common greed of monetary benefits by that of Bryce Taylor.However, Ironically for Bryce Taylor benefit his legal aid, lawyer Geoffrey Robertson â€Å"was the tutor of a textbook that analyses and deplored that absence of any privacy law In Britain† which represents to the reader Robertson's extents knowledge within the topic of privacy, Wealth Robertson's defense of Bryce Taylor he states when Diana places her self in the gym â€Å"It was like working out in a shop window† representing that her privacy was automatically violated and she's â€Å"nonetheless been inviting It to happen†.Thus puts us in a position to view Diana as someone who manipulates the Edie in order to suit her own ends. Robertson also states her relationship with the media as ‘a Faustian bargain' which refers to the story of Faust who sells his soul to the devil in order to gain greater power. This again supports Robertson's use of the disjunction of ‘bur In â€Å"but Diana wanted privacy only when It suited her†. Nonetheless as Robertson describes Donna's relationship with the media as ‘ a Faustian bargain' It shows that Diana had to sell her soul to the media in order to main good publicity and power.This is significantly supported by Robertson use of the metaphor In the concluding paragraph † In 1997 Diana was killed fleeing the flashbulbs† which has Robertson positions us to see Diana as someone who seeded the attention of the media and as this back fired she tried to ‘flee' where the consequence became death. Just like that of Faust who sold his soul to the devil , regretted it and was sent to hell. Therefore Robertson believes It's her own fault for her lack of privacy.

Lost in the Desert Essay

Question 1. Given the conditions, what should Henry do to try to save Mark? He must decide very quickly. Mark has very little time left and may not survive the trip by helicopter to the hospital. What has caused Mark’s weakness, nausea, disorientation, headache, and low blood pressure? Why isn’t he sweating? Henry can do two things to immediately help Mark and his current physical condition. First, Henry should put clothing on Mark. Although Mark may feel very hot, his skin has already been exposed to the intense UV sunrays for an extended period of time. Continual exposure to these rays will worsen the severity of Mark’s sunburns. Henry should also start administering Mark diluted fluids that contain essential electrolytes, which to help restore hydration to Mark’s body without running the risk of his plasma becoming hypotonic from water intoxication. Mark has lost a lot of water through sweat and this combined with the intense heat of the sun has caused Mark to have heat stroke. The heat stroke and profound water loss is causing Mark to feel weak, nauseous, disoriented, have low blood pressure, and a headache. Water loss will especially have a large effect on Mark’s physical state because it will directly affect the blood pressure in his blood vessels due to water leaving the cells. Extreme water loss is also evident due to Mark’s lack of visible sweat. Hyperthermia has caused Mark’s heat loss process to become ineffective. In the extreme heat conditions, the heat stroke causes the skin to become hot and dry. Mark’s dehydration and heat stroke made it so that his body cannot produce sweat. (Mario) Question 2. Why didn’t the paramedic give Mark bottled water or distilled water rather than an electrolyte/glucose solution and what is an isotonic solution? In isotonic solutions, cells will be able to maintain their shape and size. This is due to the ability of water to move into and out of the cell when in this environment because the solution and solute concentration is at an equilibrium. The paramedic administered  Mark the electrolyte/glucose solution to help replace essential substances that Mark may have lost due to sweating or from being exposed to the harsh elements of the dessert. If Henry, the paramedic, were to give Mark a drink that was lacking the proper ratio of electrolytes/glucose to water, he could risk exposing the cells in the body to a hypotonic state, in which the cells would burst, or a hypertonic solution in which the cells would lose even more fluid. (Mario) Question 3. Why DID Mark become disoriented? How would you test your ideas to see if you are right? What does your group think based on the information in the text? Mark became disoriented because he was experiencing heat stroke. To see if I was right I would research the symptoms of heat stroke, and see if Mark had any of the symptoms. (Kassie) Question 4. What should Mark be concerned with regarding these moles? He talked to dermatologist, Dr. Charles Culp about the moles. What test might Dr.Culp conduct after removing the moles? Mark should be concerned that he has developed melanoma from his exposure to the sun without wearing sunscreen. If the dermatologist can tell for sure that the mole contains melanoma cells, special tests may be done to confirm their diagnosis. These tests that can be performed are called immunohistochemistry, fluorescence in situ hybridization, and comparative genomic hybridization. (Kassie) Final Set of Case Study Questions Question 1. Define the terms in the case study highlighted in boldface. Heat stroke is the condition in which the skin becomes hot and dry as the body temperature continues to rise. Damage may be done too many organs, such as the brain, due to the lack of blood flow. First-degree burn is a burn that affects only the superficial skin/first layer Electrolytes substance that ionizes in a water solution Glucose is a monosaccharide in blood that is the primary source of cellular energy Melanin is dark  pigment formed by cells called melanocytes (Kassie) Question 2. Assuming that Mark lost around 4 liters of water, what percentage of his body water did he lose? Would you expect his urinary volume to decrease or increase during his trek? Please explain your answer. If Mark, weighing 77 kg (average male weight), were to lose 4 liters of water that would be around 10% of his total body water. In his dehydrated and heat stroke state, Mark’s body would need to conserve water. I would expect Mark’s urinary volume to be decreased because he is dehydrated he isn’t in taking any liquid for him to be voiding out. (Vanessa) Question 3. Why was Mark’s blood pressure so low? Would his pulse rate decrease or increase? Also why was Mark dizzy and disoriented? Please explain. Mark’s blood pressure was really low because he was very dehydrated. Also because he is dehydrated and not in taking any fluids his blood pressure will continue to lower because there is no blood volume for his body to circulate his blood. Mark’s pulse rate will now increase, to try and raise his blood pressure to normal. Mark is dizzy and disoriented because he is dehydrated, and has a low blood pressure and pulse. Being severely dehydrated altered Mark’s brain and nerve function, making him feel very dizzy and disoriented. Also Mark’s low blood pressure and low pulse would make him feel dizzy because it is slowing the rate at which blood flows to his brain, lowering the levels of oxygen and making him feel light headed. (Vanessa) Question 4. Assume that Mark had an unopened six-pack of beer in his car. Would it have been a good idea for Mark to bring the beer along in case he got thirsty? Why or why not? Beer is known as a diuretic, which increases a person’s overall urine output. It would have been a bad idea for Mark to drink an unopened six-pack of beer for many reasons. Because beer isn’t water, it will eventually add to Mark’s dehydration by increasing his sodium levels and his urine output, both of which will make his cells in a furthered hypertonic state. This will also throw off Mark’s  electrolyte imbalance, adding to his cell’s hypertonic state. (Vanessa) Question 5. What vitamin would Mark have in greater amounts in his body after that day and what role does the vitamin play in the body? After spending an extended period of time in the sun, with no protection from the sun’s UV rays, Mark would have a great amount of vitamin D built up in his body. Vitamin D can be absorbed from dietary supplements or few foods, it is naturally produced when the sun’s UVB rays reacts with cholesterol. Vitamin D’s main role is to promote calcium absorption, as well as aid in bone growth and remodeling. Vitamin D also regulates cell growth, neuromuscular and immune function, and reduces inflammation. (La) Question 6. What did Mark do that increased his chance of burns and what could he have done differently? Mark took his shirt off as the heat intensity rose throughout the day. This exposed his unprotected skin to the sun’s harsh UVA and UVB rays. Not only was Mark not wearing any protection from the sun, but he also failed to wear sunscreen, which would have helped to shield his skin from the sun’s rays. If Mark had been wearing sunscreen or clothing to protect him from the sun, he may not have gotten such severe burns. (La) Question 7. Why would Mark’s skin have looked red within the first few hours of his adventure rather than redness developing hours and days later as a result of â€Å"sunburn†? Mark’s skin will appear red within the first few hours of his adventure rather than redness developing hours and days later as a result of sunburn because of blood in the dermal vessels adds color to the skin. When blood well oxygenated, the blood pigment hemoglobin is bright red, making the skin of light-complexioned people appear pinkish. (La) Works Cited Shier, David, Jackie Butler, and Ricki Lewis.

The Cold War During World War II - 933 Words

The Cold War started before the end of World War II. It was a conflict between two great powers, the Unites States (and their allies), and the Soviet Union (and their allies). It was a race for control over the post war world. Both countries tried to spread their ideology across the world. This rivalry lasted for about 45 years. However, it was not like every other war. Fighter planes did not fly over countries to drop bombs, there were no deployment of troops, and no ground troops. The two sides never directly engaged in a battle. It was fought at different levels and in multiple different places. Although it was not a battle like other typical war, tons of money were spent on this war, especially on nuclear weapons. Europe was split into east and west, and the competition between the United States and the Soviet Union was ridiculous which included every aspect of life. Many decisions made by Presidents, namely Dwight D. Eisenhower, and John F. Kennedy caused an impact on United St ate politically, economically, and socially. Dwight D. Eisenhower was elected U.S President in 1952. By a landslide, he became the 34th President. He served two terms, 1952-1960. When President Eisenhower came into the presidency, he constantly attempted to discover ways in which the U.S may be able to use strategic and nuclear weapons to stop fighting.
