Understanding lab tests - Essay Example Every Year nearly 1.5 million individuals in the U.S. suffer a heart attack (Acute Myocardial Infarction) and of these approximately 500,000 die. Ischemic Heart Disease is the principal cause of death in the U.S."This can be achieved by adding cardiac biomarkers in the artillery. ECG is the primary diagnostic tool which is nearly 100% specific but sensitivity is only63-82%. Gold standard of investigation for detecting Acute Myocardial Infarction is CK-MB; Cardiac specific Troponin can be added to this for better results. Coronary artery disease to a major degree is due to atheroma and its complications mainly thrombosis. Elevated LDL cholesterol is the single contributor of atherosclerosis LDLc, gets deposited in subendothilial layer of intima of the artery. This deposited LDLc can be removed from the site by HDL. But when triglycerides increases it is associated with decrease in HDL, this decrease in HDL cannot effectively remove LDL, thus helping atherosclerosis.LDLc as such cannot initiate inflammatory response. It needs to be oxidized, which is .brought about by free oxygen radicals. The rise in oxidized LDL in sub -endothelial layer increases the oxidized LDL in the blood and is a highly sensitive index of atherosclerosis. Oxidized LDL causes release of Vascular Cell Adhesion Molecule from endothelial cells. This causes adhesion of monocytes to endothelial layer. Oxidized LDL also causes release of Monocyte Chemo Attractant Protein1 (MCP1) which facilitates entry of monocytes into sub endothelia l tissue. Here they converted into macrophages .They absorb cholesterol to form foam cells. The oxidized LDL also gets absorbed on to the surface receptors of the scavenger cells. These foam cells accumulate beneath the sub -endothelial layer of the arteries to form fatty streaks. The foam cells then liberate some factors which cause migration and proliferation of smooth muscle cells; these surround the foam cells and induce formation of collagen. The foam cells eventually die off liberating cholesterol in the cavity. Thus atheroma has a central core of cholesterol with a fibrous cap. http://images.medscape.com/pi/editorial/cmecircle/2002/2036/figure-2-large.jpg The free oxygen radicals cause endothelial dysfunction by inactivating released nitric oxide and inhibiting nitric oxide synthesis. The endothelial dysfunction contributes to atherosclerosis since normal endothelium releases nitric oxide which in turn inhibits VCAM. Diabetes, smoking, hyper tension, hyper homocysteinemia and increased LDL cholesterol all contribute to oxidative stress. Thus atherosclerotic artery disease begins with a fatty streak on the blood vessel surface which may enlarge to form fatty plaque. The subsequent narrowing of the arteries may eventually lead to disruption of the plaque and to thrombus formation with further reduction of blood flow, thus paving the way for acute myocardial infarction. Complete obstruction of blood results in myocardial necrosis within 20 minutes with maximum irreversible injury occurring within 6 hours. So the restoration of blood flow to the damaged myocardium within two hours but not later than 6 hours can salvage it. http://labs.ansci.uiuc.edu/meatscience/Library/309%20lipid%20transport.gif http://medtech.hcu.ac.th/pic/lipid.jpg Lipid profile Lipid profile is a group of tests to find out the level of LDL, VLDL, HDL, Triglycerides, Total Cholesterol, and T.Cholesterol / HDL ratio. This is used alone or in combination with other risk factors like age, gender, BP, smoking in Framingham score or along with other biomarkers in predicting the risk of a/c Myocardial Infarction.

A piece of writing of Graphene Essay Example | Topics and Well Written Essays - 1500 words

A piece of writing of Graphene - Essay Example The interesting thing about graphene is that it has huge power along with adequate electrical conductivity and elasticity. Graphene is actually a significantly huge aromatic molecule. Graphite can get its crystalline form by combining a number of sheets of graphene together. Graphene is regarded as the most fundamental structural component of a few carbon allotropes. For example, graphene lays the basis of graphite, fullerenes, charcoal, etc. The discovery of graphene has immense significance as various new possibilities of research in the area of physics have opened up. Researches in graphene have also helped in opening up huge scopes of its application in high-tech fields. Graphene is considered to be one of the most potential and adaptable components that have ever discovered in the area of physics. (Geim; 2009; Sakamoto 2009). The production of Graphene: Graphene can be separated from graphite as an isolated plane of carbon atoms. People now know that a minute portion of graphene sheet can be produced by abrading graphite. For example, one can get a tiny piece of graphene sheet when one draws a line on paper with a pencil. (Geim; 2009). During the year of 2008, the production of graphene used to be done by exfoliation. This graphene produced through such exfoliation was considered to be one of the most costly components in this world as this component which so small that can be placed on a tiny portion of the cross section of human hair did costs around as much as $1000 in 2008. Since, 2008, the process of exfoliation has been increased and various companies are now selling graphene in huge amount. Researchers have also discovered cheaper version of graphene (Segal, 2009). For example, Korean researchers have produced cheap graphene through the process of transfer of nickel. Graphene can, in fact, be produced by employing different types of methods. Some of the production processes of graphene are listed below: Producing Graphene through Drawing Method: The drawing method is actually a modified version of exfoliation method. Earlier, in this method, a solid tape was used to repetitively divide crystals of graphite into more thin prices to form graphene. The extremely thin flakes of Graphene then used to be dissolved in liquid acetone and after a few steps they were to be sedimented. Over time, the technique of drawing graphene from graphite has been simplified. Particularly, major modification has been done in the step of disposition. Instead of making graphene floating in acetone, the scientists have started to use the method of dry disposition of flakes. (Geim and Novoselov, 2007) Production through heating silicon carbide: Another popular process of producing graphene is heating silicon carbide at a high temperature in order to reduce it to graphene. In this process silicon carbide is heated at more that 1100 degree centigrade. In this method, the dimension of the graphene produced depends on the dimension of the silicon wafer. The face of the silicon wafer which is utilized for the formation of graphene, has significant capacity to influence the density and the level of mobility of graphene. If graphene is produced using this method, then a number of properties of graphene can clearly be visualized. For example, in the graphene produced through heating silicon carbide a kind of feeble anti-localization of the component can be

Four stages of the learning cycle Essay Example for Free

Four stages of the learning cycle Essay During our final chapter, we discussed the four stages of the learning cycle. The four stages of transformational learning are as follows: recognizing a significant problem, confronting it intensely, finding a solution, then integrating a new perspective and a new set of assumptions into ones’ life pattern. I think that a lot of times people go through life not realizing when they have a problem. Therefore, acknowledging your problem is most definitely the first step in learning from it. When you realize that there is a problem, you must confront the problem head on to find a solution. Once you have found a solution, you need to incorporate it into your life. These four stages are important in any learning experience. The transformational experience that I will use for my example is very personal. I used to be in a very abusive marriage. My marriage was damaging to me as a person, and damaging to my children because it prohibited me from making anything of myself. I would always make excuses for my lack of productivity, stating that I couldn’t do anything with my life because my husband wouldn’t let me. Finally, in 2011, I realized that I was wasting my life. The only thing that my daughter was ever going to learn from me, was how to let someone else run there life and impact her choices. We would never have had a normal life! When I realized what I was doing to myself and to my kids, I knew that I had a significant problem. I confronted the problem, and I was very intense about it. I tried marriage counseling, personal counseling, and biblical counseling. I tried talking with my ex, and I sought advice from many people whom I really believed could help. After exhausting my resources, I knew that the only logical solution was to take my children out of the abusive situation and start from scratch. I chose to go first to the police for help, and then to battered women’s shelter. The women’s shelter helped us to move away and start over. I have now been away from him for a little over two years, and I am in my first healthy relationship. By integrating my new perception, I was able to go farther in the past year than I ever did in all of the years of my former relationship. I am now a business owner, I am in school, and I am getting married to a wonderful man who loves me and my children. My children now get to grow up in a loving family and a healthy environment. I am now able to say with confidence that I am doing my best to be an example for them. This was most definitely a transformational learning experience for me. I think that in my experience the main stage that applied in my life, was the integration stage. It is often easier to recognize a problem, and even to find a solution, than it is to follow through on change. Often times the follow through is not so simple. There were numerous times during that relationship where I knew the problem, and the solution was apparent, however I didn’t believe in myself to integrate the solution it into my life. I believe that truly integrating a new perspective, and changing your assumptions is a very difficult stage to master. I am glad that I was able to make it through that final stage, and to become the person I am today. I still have a long way to go, but I am proud to be so far from who I once was.

Dwarfism Essay -- Exploratory Essays Research Papers

Dwarfism Although people are different in many ways, few differences are more obvious than dwarfism. Because dwarfism is relatively rare, not many worry about unprejudiced treatment of dwarfs.But dwarfs deal with the same issues as â€Å"normal† people, while also trying to overcome the problems posed by their abnormally small height. The novel Stones from the River makes us aware of these problems and raises questions:What is dwarfism?And how do dwarfs feel about their conditions? And how does people’s treatment of dwarfs affect their outlook on society in general? â€Å"Dwarfism† is a term used to describe the condition of those whose bodies are significantly smaller than the average person’s.A dwarf may suffer from medical problems, which can lead to many deformities and complications throughout life.The deformities of some dwarfs, according to the Little People’s Research Fund website, can lead to extensive disabilities, paralysis, and even death.Over one and a half million people in the United States suffer from some condition of dwarfism (Billy Barty).What many do not know, however, is that most dwarfs are born to families that have no history of dwarfism in their families. There are many different types of dwarfism that researchers have confirmed today, but there still are many genes for dwarfism that remain unidentified.The most common of these known causes is achondroplasia, a bone growth disorder.The Little People Online website states that most dwarfs who suffer from achondroplasia are born to â€Å"average-size† parents, and that their birth rate is somewhere between onein26,000-40,000www.lpaonline.org).The main characteristics of this form of dwarfism are normal trunk size with short appendages, irregularly large heads wi... ...e dealing with her own emotional turmoil over accepting herself for who she is.Trudi, like other dwarfs of the past and present, is forced to accept who she is.

14 Points Woodrow Wilson

President Woodrow Wilson’s Fourteen Points On January 8, 1918 President Woodrow Wilson gave a proposal to Congress which outlined the post World War I peace treaty later negotiated at the Paris Peace Conference, and in the Treaty of Versailles. The fourteen points were intended to generate support for Wilson’s vision of the postwar world, both home & also among allies in Europe. The president hoped that the promise of a just peace would be embraced by the populations in enemy nations and generates momentum for ending the war. When comparing Avalon Project ( primary) & History World (secondary) documents for Woodrow Wilson’s Fourteen Points, I found that the primary document is the actually proposal. There is nothing creative about it. It is just what Wilson stated. When reading the primary I had no understanding of what was being presented to both houses of Congress. In Wilson perspective it was for the Congress, to discuss the objects of the war and the possible basis of a general peace. As, I read the secondary source document, I fully understood the proposal. The writer generated this version for the people. He shortened and paraphrased it but, I was able to understand the document. Indeed the Avalon Project (primary) version was more information then what was needed because he was presenting it to Congress so it had to be in a certain form & most important professionally presented. That document is more of the original. So it is supposed to be more into details. With the History World (secondary) version the information w

Definition and Examples of Echo Words in English

In linguistics and composition, the term echo word has more than one meaning: An echo word is a word or phrase (such as buzz and cock a doodle doo) that imitates the sound associated with the object or action it refers to: an onomatope. Also called an echoic word.  An echo word is a word or phrase (such as shilly shally and click and clack) that contains two identical or very similar parts: a reduplicative.An echo word is a word or phrase that recurs in a sentence or paragraph. Examples and Observations Sound alone is the basis of a limited number of words, called echoic or onomatopoeic, like bang, burp, splash, tinkle, bobwhite, and cuckoo. Words that are actually imitative of sound, like meow, bowwow, and vroom--though these differ from language to language--can be distinguished from those like bump and flick, which are called symbolic. Symbolic words regularly come in sets that rhyme (bump, lump, clump, hump) or alliterate (flick, flash, flip, flop) and derive their symbolic meaning at least in part from other members of their sound-alike sets. Both imitative and symbolic words frequently show doubling, sometimes with slight variation, as in bowwow, choo-choo, and peewee.(John Algeo and Thomas Pyles, The Origins and Development of the English Language, 5th ed. Thomson Wadsworth, 2005) Repetitions help to echo keywords, to emphasize important ideas or main points, to unify sentences, or to develop  coherence  among sentences. Skillful repetitions of important words or phrases create echoes in the readers mind: they emphasize and point out key ideas. You can use these  echo words  in different sentences--even in different paragraphs--to help hook your ideas together...[E]cho words may  come  any place in the sentence: with the subjects or the verbs, with the objects or the complements, with prepositions or other  parts of speech. You need not always repeat the word exactly; think of other forms the word may take, such as  freak, freakiness, freakishness  (nouns),  freaking  (participle),  freaky  and  freakish  (adjectives), and  freakishly  and  freakily  (adverbs). (Ann Longknife and K. D. Sullivan,  The Art of Styling Sentences, 4th ed. Barrons, 2002) Echo-Pairs   Echo-words are  crucially different from straight reduplicated words in that they have rules sensitive to the reduplicated configuration, detaching melodic elements from the affixal skeleton and replacing them with an invariant onset (McCarthy and Prince 1986, 86). This accounts for the ban on auto-reduplication of echo-words themselves.  Yiddishized English shm-initial words undergoing echo-pairing (such as shmaltz) have to be echo-paired with something else (usuall shp-: shpaltz) or else with nothing (no echo-pair can be formed), but certainly not with a direct repeat (**shmaltz-shmaltz is disallowed). ( Mark R. V. Southern,  Contagious Couplings: Transmission of Expressives in Yiddish Echo Phrases. Praeger, 2005)

Media s Growing Sexualization Of Women - 1402 Words

If you turn on the television or flip through a fashion magazine, it is very likely you will presented with many displays of hypersexualization of girls and women in advertising images and in media. There are many components to sexualization. It occurs, according to the American Psychological Association, when â€Å"a person’s value comes only from his or her sexual appeal or behavior, to the exclusion of other characteristics.† This person is held to a standard that equates physical attractiveness with being sexy. â€Å"Sexualization† happens when a person is sexually objectified- that is, made into a thing for others’ sexual use, rather than being seen as a person with their own independent actions and abilities to make decisions. Oftentimes, sexuality is inappropriately imposed upon a person without their knowing it or consent. Sometimes, researchers use the word â€Å"hypersexualization† to describe roughly the same idea. In the article, â⠂¬Å"Media’s Growing Sexualization of Women†, hypersexualization is defined as, â€Å"The act of making something extremely sexual and erotic.† The hypersexualization of females is fairly prevalent across different cultures. The media seems to be bombarded by it; magazines are plastered with risque images of barely clothed woman and even young girls.
