Assessment and management of Barrett's disease Essay

Assessment and management of Barrett's disease - Essay Example This condition is seen more commonly in later age. Barrett’s esophagus is a pre malignant condition in which changes of dysplasia and carcinoma reported. Patients having Barrett’s disease have 30-40 fold increase risk of developing carcinoma- esophagus. To critically understand the disease, first we have to learn normal esophageal defence mechanism because most of the cases this disease is result of failure of esophageal defense mechanism. The lower esophageal sphincter, which is a localized area of specialized smooth muscles cited at distal end of the esophagus, is the main barrier to reflex. This sphincter is normally contracted thus creating a zone of high pressure so preventing the passage of gastric contents into the esophagus. In normal subjects the esophageal sphincter relaxes during swallowing but at other times there are spontaneous transient relaxations. In those with reflex esophagitis, reflex is increased because the normal or resting pressure of the sphincter is reduced and number of transient relaxations is increased because the sphincter is situated below the diaphragm, its high pressure is reinforced by intra abdominal pressure, moreover the oblique entry of esophagus into the stomach ensures that the intra abdominal esophagus is closed when the stomach is distended. These mechanisms are lost when the lower esophageal sphincter moves proximally to be situated above the diaphragm. Once reflex has occurred, rapid clearance of acid from the esophagus into stomach limits its contact with esophageal mucosa and this effective clearance depends upon secondary peristalsis and the presence of saliva and is enhanced by the erect position. It is impaired in supine position. Barrett’s disease is commonly seen in later age groups. It is divided into short ( 3 cm), according to the length of

Reflection - Reduced harm tobacco - Essay Example Furthermore, the article contextualizes this lieu of the progress of corporate social responsibility and product harm reduction of tobacco companies, or lack thereof. Corporate social responsibility among tobacco companies is very much like a paradox; basically tobacco companies are like giving a poison to their consumers so that they can kill themselves. If we were to apply the logic of corporate social responsibility to the tobacco companies, we are presented with a situation that simply contradicts itself: if a tobacco company becomes a socially responsible corporation, it would be as if they will offer a slower poison to their consumers so that they will not dies as fast as before. The addition of the snus in the tobacco industry may be seen as the slower poison. It is not smoked so that there is a significant reduction in the risks of having diseases that are more likely to be acquired when smoking cigarettes. However as the article has pointed out, even with the existence of this less harmful tobacco product, it is not supported by legislation bodies and no tobacco companies are making an effort to pursue its development or more importantly, reducing the harm in their products. This is the point where corporate social responsibility among tobacco companies hits a dead end. Tobacco companies may be aware of this contradiction and that is why most of them are not making any efforts to reduce the harm in their products. Another contradiction in this situation that the article points out is how governments demonize tobacco companies while providing them a legal status. This is counter-intuitive to corporate social responsibility since it simply does nothing to affect the market demand that is fueling tobacco companies. As a result, there is no motivation for them to develop a less harmful tobacco product since their killer product rakes in the profit, and in the end that is all that matters for them.

Identification of Micro-Organisms Term Paper Example | Topics and Well Written Essays - 3000 words

Identification of Micro-Organisms - Term Paper Example As micro-organisms have a colorless natural state when viewed through a light microscope, the organisms must be stained in order to be visible. Staining imparts a color to the micro-organisms’ by the reaction of the dye with certain structures of the microorganism (Tortora, 2006, p69) A simple stain is alcohol or aqueous based solution of a singular basic dye and its main purpose is to highlight an entire micro-organism in order for its cellular shapes and basic structure to be observed under a microscope (Tortora, 2006, p69). In this experiment, methyl blue was used as the simple stain to view microbes obtained from cheek and tooth-scraping. The illustrations on page 3 under the heading ‘Scientific Drawing 2’ shows the images that were observed. Figures 1.5 at x400 magnification and 1.6 at x1000 are scientific drawings of the eukaryotic epithelium cells obtained from a human cheek. When viewed at x1000 magnification most of the internal structures of the cells got from the cheek could be seen under a light microscope. Figures 2.3 and 2.4 are scientific drawings of prokaryotic bacterial cells obtained from human teeth scrapings. The bacterial cells, which are approx 1Â µm in diameter, are much smaller in comparison to the human cheek cell and hence the internal structures could not be observed even at x1000 magnification. Unlike simple stains, differential stains react differently with each bacteria and therefore can be used to differentiate between each type of bacteria (Tortora, 2006, p69) The most commonly used differential stains are Gram stain and Acid fast stains and the staining procedures involve several steps. In this experiment, Gram stain was used to distinguish between gram positive and gram negative bacteria, taken from a vaginal and a urine specimen. Figures 3.1and 3.2 are scientific drawings of gram positive and gram negative bacteria respectively as viewed under a light microscope at x1000 magnification.

Summarize the content of the BBC article titled 'Is language unique to Essay

Summarize the content of the BBC article titled 'Is language unique to humans' - Essay Example What gave rise to language in humans is the need to represent human ‘action’. Beyond this utilitarian purpose, through evolutionary mechanisms language has now developed into a tool for imagination and abstract thought. Several species of whales, monkeys, birds and lizards have been shown to communicate using their language of signals. Yet, this sensory based communication cannot be considered language. A language system is identified through the components of words, logical phrases, complete sentences and a set of grammar rules. While surely parrots can memorize hundreds of words and phrases, they are incapable of making sentences on their own. Likewise the intellectual capacities of higher apes are not sufficient for them to imagine through the use of language. To this extent, language is a uniquely human feature. Our language allows us to write sublime poetry, just as it allows us to write nonsensical (yet grammatically correct)

Chapter 21 Question 3 - Essay Example Because of this reason the cost of capital starts first to decline to a point where it achieved an optimal mix of debt and equity. If a firm uses too much debt financing, its overall risk profile start to increase. With more debt, the cash flows of the firm started to get strained because of the high proportion of them going for debt servicing. This reduces the free cash flow available to the firm which is one of the essential indicators of the value. It is because of this reason that the required rate of return on equity capital of the firm starts to rise thus increasing the overall cost of capital of the firm.
