Implementation and Modification IP 4 - Essay Example This report gives an account of the effectiveness of the Medicare program and provides a futuristic approach towards the program and systems of implementing the changes (Moon, 2006). The topic "Strengthening and Improving Medicare" elicited various views from both public and private entities and individuals. The congressional subcommittee of health held a forum for persons of concern to give their witness accounts on the topic. Some of the prime witnesses who stood before the subcommittee include among others, Robert Berenson, the senior consultant officer at Academy Health, Foster, Richard, Buddy Robert, a beneficiary of the Medicare + Choice health plan and Grealy, Mary, the President of Healthcare Leadership Council. All these witnesses gave individual accounts of the success of the current Medicare system and gave recommendations on ways of improving it. According to Berenson, the well-established and effective Medicare program is being replaced by the Medicare + Choice program, which shifts focus from the government provided healthcare to private health insurance. There is no evidence to prove that shifting to such a system will reduce the program’s expenditure or improve on its financial position. The only entities to benefit from the new program will be private health insurance institutions, which will only serve to segment adversely the insurance pool and increase costs of maintaining the traditional program. Through her statement, Grealy, advocates for the introduction of a prescription drug benefit to boost the financial as well as healthcare quality of the Medicare program. According to the Healthcare Leadership Council (HLC), the 50 percent increase from $6,200 to $9,500 in cost of Medicare for one beneficiary by the year 2013 will have no significant improvement in the program’s quality of an outpatient prescription drug coverage is not included in the program. The HLC advocates for the establishment of a Medicare delivery module that incorporates the aspects of competition, flexibility and invests in beneficiaries who have consumer choice power. Through such a measure, Medicare would be able to provide similar benefits to employer-sponsored programs, which offer benefits such as outpatient prescription drugs, the ability to choose a health program that best suits individual needs and reduce out-of-pocket costs and. The Medicare + Choice plan reduces the number of services offered to Medicare beneficiaries because it receives lower payments than the previous fee-for-service Medicare program. Through this, the Medicare + Choice plan has increased beneficiary cost sharing, which squashes the chance of fair competition in healthcare provision (CEC, 2003). Robert Buddy, a beneficiary of the Medicare + Choice health program gave his account of the benefits of the Medicare Program and the Medicare + Choice plan, which he joined after the privatization of the Medicare program. According to Robert, the Medicare program did not offer comprehensive benefits thus had to spend at least $2,000 on a Medicare Supplement policy to gain more healthcare benefits. Emphasis of the Medicare + Choice plan is early detection and treatment, which affords better healthcare to its beneficiaries. Robert recounted the case of his father, who was on the Medicare prog

Marketing Mix Essay 1.1 Background to the Report Strategic management refers to analysing the important initiatives which are taken by the top management of the company on behalf of the owners. It successfully keeps a track of day- to- day activities which are going into an organization to organise the resources and plan a strategy which the organization should follow in order to get benefit in the business. It provides a direction to the organization and is closely related to the field of organizational structure. (Hambrick, 2007) In this report, strategic management of Singapore Airlines is critically evaluated on the basis of several strategies used by them. This not only helped the company in achieving the results but also enabled SIA to expand itself in the global market as well as establish a new base in the new expanding countries. 1.2 Aims of the research are – To develop a good understanding about what involves in Strategic management. To develop knowledge about constituents of strategic management process. Critical assessment of strategies of a selected organization. To throw some light on the internal and external environment of selected organization. Gap analysis for Singapore Airlines – 2. Analysis of internal framework of Singapore Airlines – Capability to restore competency in order to attain similarity with the change in business environment are termed as dynamic capabilities. This is done by reconfiguring, mixing and adjusting external and internal resources, skills and abilities (Teece et al., 1997). 2.1 Resources – Connecting strategic resources and core strategies is defined as ‘configuration’ by Hamel where core competencies and assets, process and assets are organized and combined in order to maintain strategies (Hamel, 2002). Resources are divided into two categories, tangible and intangible resources of Singapore Airlines. They are further divided into sub categories on the basis of which it can be assessed that core strategies and strategic resources were well connected. 2.2 Capabilities – On the basis of broad variety of competency and technological expertise in newly invented planes, Singapore Airlines effectively fascinated more airlines clients to its fleet management industry, securing its place as major fleet management facility providers of the world. It also persists on expanding its potential by means of strategic joint ventures. For instance, a joint venture agreement is signed by SIA with Panasonic Avionic Corporation in order to prepare a facility for maintenance, repair and operation of communication and in-flight entertainment. Facility will be based in Singapore and components will be generated by Panasonic Avionics (Singapore Airlines, 2011). 2.3 Core Competencies – Core competencies of Singapore Airlines consist of the interpersonal talents of its flight assistants and ability of its top level management in planning strategies for marketing. They endeavour to make flights as relaxing as possible (Singapore Airlines, 2011). 3. Analysis of external framework of Singapore Airlines – PESTEL Analysis FactorsSingapore Airlines PoliticalUnpredictable, SIA reject Air India offer EconomicSIA offer created trouble in Hong Kong SocialSIA Airplane crash in Taiwan TechnologicalQuick technology implementation EnvironmentalLaunch of A380 Air career LegalPassengers safety 4. Five forces of porter – Porter’s five forces model deliver a well-liked external analysis framework for Singapore Airlines. After analysing the internal and external framework of Singapore Airlines, S.W.O.T analysis is performed in order to assess SIA’s capabilities, followed by the critical analysis of corporate and business level strategies. 5. S.W.O.T. Analysis – Strengths – Singapore Airlines has an expanded geographical reach. They operate in a number of reasons like US, West Asia, Europe, Africa, South west Pacific and East Asia. They run flights to 63 cities globally, whereas its division Silk Air is offering flights in 12 countries with 39 cities. Considerable amount of revenue is generated by SIA group with its airline operations around the globe. Equally spread and diversified revenue base guarantees that group is not dependent on single geographic market for most of its profits, by which business risk decreases significantly. Though, SIA is basically a passenger airline, but the group is also offering various specialized services like engineering services, airline operations, cargo operations, etc. which are providing them stability by diversifying business threats. Additionally, SIA group has a policy of maintaining young aircraft fleets, which emit lower carbon emissions and have less burning of fuel per kilometres. This is also strength of SIA group as this factor helps in keeping maintenance costs less, along with reducing performance related security concerns (Heracleous, 2006). Weaknesses – SIA faced extremely competitive market in its initial phases. Many countries restricted air-route access to protect national airlines from other competitions. SIA worked hard to get access rights for many important airports (eg. Heathrow, Manchester) (Reddy, 2004). Various competitive authorities keep on investigating about Singapore airlines and its subsidiaries. For example, South Korea, Canada, Australia, South Africa and European Union investigated about SIA group in order to determine whether the rates, surcharges, and other characteristics of cargo service were determined lawfully or not. In financial year 2012, SIA paid administrative penalty to South African competition commission (2.8millionUSD) as settlement. Legal expenses connected with the inquiry and court case and time spent on this issue left an impact on SIA’s business and operations. Opportunities – Singapore Airlines with its well-built base of operations and proficiency, is well placed to reap advantages from the worldwide boom in tourism industry. This would help SIA Group to produce extra profits. Also, group is focusing on joint ventures and strategic operational alliances to add opportunities for growth and sales. SIA entered into partnerships (jetblue Airways) and code-sharing agreements (Virgin Australia/ Virgin America) in order to increase growth opportunities. For instance, SIA signed code share agreement with Virgin America in December 2012 (SIA, Virgin America reach code-sharing agreement, 2012). SIA will add its ‘SQ’ airline code to flights of virgin which are America-operated serving Washington DC, Las Vegas, Seattle, Chicago, etc Furthermore, SIA group has launched ‘Scoot’ which is a low cost carrier in order to grow its existence in low cost flight market. This step will enable SIA group to attract more groups of customers which will in crease its growth and revenues. Threats – Competition is very high in the airline industry. Reputation, safety records, customers service, flight schedules, fares, code-sharing relations are few parameters of competitions. SIA faces straight competition with other carriers on its route. Cathay Pacific, Japan airlines, United Continental,  AMR are few of its competitors. Extreme competition on the basis of price matching, promotions, discounting, capacity, etc. affects operating margins of SIA. Also, Natural disasters can have affect on SIA’s operations effecting the cash flows and financial state. Moreover, hike in the prices of jet fuel can increase operating costs, which can affect the profitability (Heracleous, 2006). 6. Strategies used by Singapore Airlines – 6.1 Corporate level Strategies – Diversification – Companies tend to grow their full potential in economies which are developing, with the help of strategic diversification. Strategy of diversification is followed by SIA at the corporate level. SIA group has number of primary companies with key companies being SIA Cargo, SIA Engineering Company and Silk AIR. They also have number of associated companies. Its Airlines divisions which consist of 49% ownership of Virgin Atlantic, 32 % of Tiger Airways and entire ownership of local carrier Silk Air cover basic segments of customer in the industry. This was a long-term strategy (Singapore Airlines, 2008). Benefits of using diversification by Singapore Airlines is to enable passing of learning and control quality and side by side reaping cost synergies. Subsidiaries serve as sources of learning; and also as progress arena for skills of management and corporate rather than divisional viewpoint through job rotation. Profit margins are better in related operations (like aircraft maintenance and catering) on comparison with airline business itself as structure of industry in those sectors is more favourable. (Singapore Airlines, 2008). Strategic Alliances – In April 2000, SIA joined Star Alliance as a step of its internationalization strategy. In the three main airline alliances, Star alliance hold its place  with Oneworld and Skyteam. Also, In India and China, SIA Group were investing through planned deals during this time. Deals were done with local services like engineering services, cargo85 divisions, catering and airport services. SIA is also under a code share contract with Malaysian Airlines. These airlines are offering up to 14 flights in a day between Kuala Lumpur and Singapore (Doganis, 2006). For the expansion of the company, strategic alliances are becoming more common tool. SIA used strategic alliances for increasing competitiveness in the global and domestic markets. This helped SIA in developing new business opportunities with the help of new services and products. This resulted in the expansion and growth of company globally. An alliance is a business-to-business relationship (Jeffrey, 2004). 6.2 Business level strategies – Differentiation strategy – Premium services were successfully delivered by Singapore Airlines to those customers who are very demanding and this can be termed as achieving differentiation strategy. This helped Singapore Airlines in identifying that different customers are broadly scattered, with varied needs and sufficient spending power. If an organization is unique in something which is valuable to its customers at the same time, it differentiates itself in the marketplace (Chamberline Robinson, 1996). If an offer is valuable for the customers, they tend to be less sensitive to characteristics of competing suggestions where cost may not be one among these characteristics. This accomplishment of SIA challenges viewpoint of Porter that cost leadership and differentiation strategies are equally exclusive strategies (Porter, 1985). Differentiation strategy allowed Singapore Airlines to insulate itself partially from rivalry competitors of same industry. Customers of differentiated services were less sensitive to prices and they started preferring SIA over other airlines, that is, SIA succeeded in gaining customer loyalty (Hitt et al., 2007). SIA carefully applied this strategy and played safe by delivering premium services appropriately without over-proliferating them. leadership strategy – Singapore Airlines has considerably greater effectiveness than its peer group, which is a crucial aspect of an effective leadership strategy. They have young fleets which have lower maintenance costs; they are fuel efficient and have effective hedging of fuel. Labor cost of SIA is comparatively low (16.6%) than average of all prime airlines (20.1%) (Singapore Airlines, 2008). Singapore Airlines have youngest fleets in the airline industry, which is worth considering. Their fleets have average age of 75 months, and average age of half of airline industry fleets is 163 months. SIA’s fleets are much efficient. Younger planes are quiet, comfortable and fuel efficient. They have low repair, service and maintenance costs which are all part of its leadership strategy. 7. Recommendations – Keeping in mind the weaknesses discussed above, some recommendations for Singapore Airlines come into light like keeping company information confidential. SIA paid huge fine as various companies successfully investigated about SIAs internal facts and figures. Also, they need to keep a close eye on its competitors who try to gain lead in the competition on the basis of price matching, promotions, discounting and capacity. 8. Conclusion – A variety of strategies were executed by Singapore Airlines by which the company is successful for a considerable time. By keeping a track on industrial environment and the macro environment, Singapore Airlines can uplift its capabilities to secure future success. However, as there are uncertainties in the environment and market keeps on altering quickly, it is crucial to monitor and carefully consider all the strategies before implementation.

The Creative Classroom :: Education Teaching Teachers Essays

The Creative Classroom When I was three years old, my parents and I made the most significant move of our lives– we moved from northern Ohio to my mother’s hometown in southern West Virginia. Many things about my life changed because of our relocation, but most significantly was my mom’s job. While in Ohio, she had stayed home with me, but once we came to West Virginia, she resumed her career as a teacher. Immediately, I was thrown into the school system. I remember being so proud that my photograph had been included in the 1987 Man Junior High School Yearbook– and I was just four. Since then, I have viewed the teaching profession through my mother’s eyes and consequently, the eyes of a teacher. I have seen the joy that comes with teaching as well as the frustrations, and I look forward to them all in my future as an educator. I consider my views of teaching to be realistic. I have seen firsthand the paperwork, confrontations with students, extra hours required, and the stress that comes with teaching. But, I have also seen a teacher’s entire day be turned around just because one student grasped a new concept. I have seen a student’s eyes sparkle when they discover something new. And beyond that, I have seen a teacher’s eyes sparkle when his or her pupil rejoiced in their newfound knowledge. I welcome all these experiences into my life, and cannot wait to make my own discoveries in my secondary mathematics classroom. Because of my observations of the education field and my own personal style, I feel that my classroom will best be served with a diverse group of philosophies including essentialism, perennialism, behaviorism, and social reconstructionism. Essentialism is the "back to basics" approach to education that concentrates on teaching primary skills to students. Essentialism tugs at the very heart of mathematics: in order to understand the more complex theorems and algorithms, you must first have a firm grasp of the basic principles of mathematics. I believe learning mathematics is both a step-by-step and conceptual process. With essentialism, I hope to highlight the step-by-step approach. In this, I will be constantly reviewing elementary mathematical concepts, building to a better understanding of the given concept and further building up to a more complex mathematical understanding. Perennialism emulates the belief that ideas that have lasted over centuries should be the concentration of the classroom.

Camus: On and In Action :: Camus Essays

Camus: On and In Action ABSTRACT:In this paper I wish to examine the position of Camus regarding social change, namely his concepts of rebellion and revolution. I in no way question his well-deserved status as a major twentieth-century French writer, nor do I wish to suggest that he may have been someone caught in a Sartrean notion of 'bad faith.' I am concerned with what one might call his theory of social action. I do wish to assert that Camus was a good man who seriously wrestled with the events of his time. Yet his claims on behalf of suffering humanity, while honest, are not sufficient when faced with complex social issues. That his move toward the right that today might well be taken for a supposed liberalism was undoubtedly bound up with his continued misunderstanding of the dialectic of history. A Series of Critical Observations Camus continually stresses the break from Christianity (God is dead—the world is without order) whether in speaking of the French Revolution or what he calls the new absolutism of the communist revolution. In the first case there is a degree of confusion on the issue when speaking of Rousseau, St. Just, and the divine right monarchies. Camus obviously holds to one traditional view of the king as God's representative on earth and from this lays the groundwork for his future project. I would like to suggest that there are at least two alternate interpretations of divine right monarchy that vie for our attention. First, there is the view forwarded by Reinhart Koselleck in his 1959 book Kritik und Krise. There in he suggests that rather than a union of the sacred and the secular, divine right monarchy already announced the triumph of the secular over the sacred. Before this period there had been the two worlds of religion and politics. With the Reformation Christianity no longer w as unified under the pope but broke into various factions. The divine right of kings, whether it is in England or France, certainly allowed for an absolutism, but relegated the religious partner to the outer fringe of politics where it was left to argue matters of theology and direct the religious faithful while recognizing the supremacy of the King in all matters political, or even, as in England, recognizing the King as leader in both matters. When Camus points to Marx's observation that the beginning of a radical critique of society is a radical critique of religion, he believes his own critical project to be partly vindicated.

Informative Speech on Leukemia Essay

Hope, denial, anger, fear, and worry are words that come to mind when we think of the word cancer. Cancer is a word we never want to hear. I’m sure at some point in your life, everyone in here knows someone who has been affected by cancer. On September 19th of this year, not even a month ago, I did one of the hardest things I was ever faced to do†¦ I attended one of my best friend’s funeral. Kali suffered from Leukemia since the young age of 10 and fought her battle until the age of 24. This topic is so dear to my heart because it was not until after she passed away that I found out exactly what she suffered from. So today, I would like to inform you about Leukemia’s symptoms, treatments, and who can be affected by it. So, what exactly is Leukemia and what are some symptoms to be aware of? Leukemia is characterized by an increase of abnormal white cells in the blood and bone marrow. In lamer terms, â€Å"Cancer of the blood cells.† If you have Leukemi a, the first thing affected are your white blood cells that fight infections. If you have Leukemia, your white blood cell count becomes almost non-existent making it extremely difficult to fight any infection. A simple cold would feel like pneumonia to a Leukemia patient. Kali told me that her immune system was equal to a 6 month old baby. In addition to your white blood cells, your red blood cells are also affected. Red blood cells help carry oxygen from your lungs throughout your entire body. If you lack red blood cells, you will most likely experience shortness of breath. This explains why at times Kali would speak very slowly in order to catch her breath. Lastly, your platelets are affected. Platelets help control bleeding and bruising on the body. When affected you are more likely to experience excessive bleeding and easily bruised. When the oncologist, a doctor that specializes in cancer, suspects that you have cancer he or she will question your symptoms. Common symptoms include fever, paleness of the skin, fatigue, pain in the bone and joints, weight loss, discomfort in the abdomen, and night sweats. Furthermore, the oncologist will perform a bone marrow biopsy. If the patient is not put to sleep, this procedure can be extremely painful. They take a 12 inch needle, stick it into your hip, and extract the bone marrow. The bone marrow is then tested to determine if you have Leukemia and wha t type of treatment is best for you. This brings me to my next point. Medicinenet states there are three major types of treatment: Chemotherapy,  steroid therapy, and stem cell transplant. With the stem cell transplant, doctors use high dosages of chemotherapy and basically remove your entire immune system and replace it with someone else’s. This person can be a related or unrelated donor. If it is a related donor, this person is usually someone very close to the patient such as a parent, sibling, or close relative. Kali was given the stem cell transplant and had new blood in her body. She informed me that her childhood vaccine shots were no longer in her bloodstream and she could not get them again because they could work against her in a negative way sort of putting her between a rock and a hard place. Like Kali, once a patients transplant is complete, they are given lots of medicine to help support the body and pain in hopes of preceding with a normal life. This brings me to my final point. Are you at risk? Can you be affected? According to the Leukemia and Lymphoma society, approximately every 3 minutes someone in the United States is diagnosed with a blood cancer and approximately every 10 minutes someone dies from a blood cancer. There were an estimated 310,000 people living with or in remission from Leukemia in th e United States. In this year alone, roughly 52,000 people were diagnosed and 24,000 are expected to die- 14,000 males and 10,000 females. While there is no known ways to prevent Leukemia, the National Cancer Institute states that developing Leukemia increases with several factors such as: smoking cigarettes and air pollution. Why should this be important and relevant to you? According to the Washington Post, Louisiana has been given the name â€Å"Cancer Alley† because of the 150 petrochemical companies and 17 refineries that line the Mississippi River from New Orleans to Baton Rouge releasing dangerous levels of toxins in the air we breathe in every day. We live in a state where cancer rates are to the roof. Leukemia is most frequent in Caucasian males than in any other population. Kali was an African American female. This lets me know, no one is susceptible. I’m sure after listening to me, you are more knowledgeable about Leukemia, its symptoms, treatments, and risks. Although it may not affect you directly, I encourage each and every one of you to get regular check-ups, stay healthy, and give to those who are affected. I’ll leave you with this quote by John F. Kennedy, â€Å"When written in Chinese, the word crisis is composed of two components, one represents danger, the other represents opportunity.†

Movie Evaluating Criteria and Standards †Humanities Informal Essay

Movie Evaluating Criteria and Standards – Humanities Informal Essay Free Online Research Papers Movie Evaluating Criteria and Standards Humanities Informal Essay The evolution and widespread use of the genre in feature films, along with the tremendous amount of releases now offered to the movie-going public has now instilled in me a sense of standards for evaluating each film I view. With the many genres, however, I find myself using a different set of sub-standards that evaluate a particular genre. The particular genres that I enjoy viewing, and, hence evaluating, are science fiction / fantasy, action, comedy, horror, and drama. I am currently writing a script for a science fiction story that could easily be used as a movie, book, or even video game. Thus, I find myself being the most scrutinizing with this genre. When I see a science fiction or fantasy movie, I usually look for projected realism. This is a term I have created for myself to evaluate the ideas and actions presented within the framework of the universe created. Obviously, science fiction or fantasy movies with magic, space warp, etc, are not going to be â€Å"realistic† in the classic sense. Projected realism means, in a direct definition, â€Å"Ok, we have this galaxy (or this magical world or whatever). Given the physical laws (magic, light sabers, etc.) that are given to us with the film, would this particular scene really happen?† For example, the Force is supposed to be this mystical controlling power that can move objects with the mind. Would Darth Vader really want to toss large metal objects at Luke if he could rationally do something else? It is unfair to discard a science fiction story by the merits of its physical laws (i.e. Bavmorda couldn’t really turn people into pigs- magic doesn’t exist!) because, by virtue of its genre, that is what the writer has created for us. What I, as a viewer, have to do is put myself into that created world and become involved with its fictional physical laws to truly evaluate it. For a comedy, it is obvious what specific constraints I put on that genre- it has to make me laugh. Although there are a few areas of gray matter, for the most part, comedies fall into two major categories: dumb comedies and smart comedies. Dumb comedies are those that are centrally slapstick, normally require breakage of the laws of physics and of chance, and do not require any sophistication to laugh at. Dumb and Dumber, the Airplane series, The Naked Gun sequels, and most spoofs are considered to be in this category. It must be understood that I enjoy most of these very much. The criterion for these, however, is unique. They must make me laugh, and must not be so poorly written that I look at it and mutter, â€Å"what the heck was that in there for?† The majority of movies that cause me to say that are those with numerous sexual jokes. Although I do admit that some sexual jokes make me laugh, for the most part, they contain very little humor and rely more on the sexuality o f the situation than the humor to cause the laughter. For the perverse, the goal is accomplished, but for myself, it does need to contain some actual humor. The sophisticated, or â€Å"smart comedies† include those that are funny, but realistic fiction- given those circumstances and those characters, the laws of nature and physics would allow that story to actually happen. Most romantic comedies, e.g. My Best Friend’s Wedding, While You Were Sleeping, are smart comedies. Unless the humorous situations are poorly written (which is essentially my central criterion), I find that the romantic comedies I dislike are few and far between. Other comedies, such as Greedy, Clue, Trapped in Paradise, and the Father of the Bride movies are also â€Å"smart† movies. They have a realistic base, and are intelligently planned out. In truth, these are the most difficult comedies to make, which is why I have such great admiration and respect for them. Horror movies must scare me; suspense movies must put me in suspense. These criteria are obvious and apply to essentially all the movies in those genres. However, I do have a set of criteria that I apply to basically all of the films I see. The first aspect of a screenplay that I notice is its meaning. If a film has no meaning, then it is merely entertainment. I do not frown on entertainment for its own sake, and, as such, enjoy many a motion picture devoid of any purpose. However, the movies that I do not mind seeing and evaluating numerous times are those that the writer intended to display a greater meaning or purpose than normally granted to the public. Additionally, when I look at a film that has a message or a purported meaning, I try to dissect the symbolism. Several years ago, I used to over-evaluate movies and try to find symbols in almost every single aspect of the screenplay, but now, with my increased maturity, I have narrowed my view to those aspects of a film that truly attempt to express a point of human truth. It is not often that I see a meaningful movie that aims to express an eternal principle and does it very well. However, this July, a film was released that exemplified that criterion and did it so well that have I gladly paid to see it three times. This was the movie, Contact, with Jodie Foster. This film expressed the eternal principle of God with such skill that I left the theater with an altered personal philosophy. â€Å"Is there a God?† The movie poses the question very directly and never attempts to definitively answer the question but displays the many complications and truths inherent in maintaining either a theistic or an atheistic point of view towards this matter. This is why I liked the movie. It denounces the classic scientific principle of â€Å"if there is no evidence, then it is not true† without denouncing science as a holistic concept. It shows that things can be true without physical evidence. The movie showed that some things just cannot be proven with our limited methods of expression and explanation. Contact definitely had a meaning. It vindicated belief without true knowledge (i.e. human impression) and vindicated a liberal view of science as the study of wholeness of the universe, including God and the scientific laws inherent in such a higher power. I sincerely doubt there was anyone who walked out of the theater without being touched in some aspect. It is a film with direct elements and symbolism to be praised and emulated.

Faculty of Science Abstraction Background Brassica oleraceaL. volt-ampere. italica besides known as Brassica oleracea italica is a cruciferous vegetable belongs to household that protects against malignant neoplastic disease. Its flowerets have been used in many states as salad. It contains phytochemicals that helps to make unsusceptibility and antioxidant support in the organic structure by bring oning excess protection of the organic structure s enzymes. The present probe purposes at measuring the hepatoprotective consequence ofBrassica oleraceaL. volt-ampere. italica ( Brassica oleracea italica ) infusion on aflatoxin B1 induced hepatic harm in mice. Methods Aflatoxins are powerful hepatotoxic and hepatocarcinogenic agents. Reactive O species and attendant peroxidative harm caused by aflatoxin are considered to be the chief mechanism taking to hepatotoxicity. In present survey, aflatoxin ( 66.6 A µg/kg bw/day ) treated animate beings showed a important addition in lipid peroxidation degree with attendant lessening in enzymatic and non enzymatic antioxidants as compared to controls. Consequences Broccoli, a cruciferous veggie which contains a assortment of polyphenolic antioxidants, showed hepatoprotective consequence at a dose regimen of 0.2 g/kg organic structure weight per twenty-four hours by take downing lipid peroxidation and heightening the degree of decreased glutathione ( GSH ) and protein contents in comparing to aflatoxin treated group. The hepatoprotective consequence was besides shown by the important addition in the activities of enzymatic antioxidants such as glutathione-S-transferase ( GST ) , glutathione peroxidase ( GPx ) , glutathione reductase ( GR ) , superoxide dismutase ( SOD ) and catalase ( CAT ) when compared to controls. Histopathological analysis of liver samples further confirmed the protective consequence of the infusion. Decisions All these findings demonstrated that, ethanolic infusion of Brassica oleracea italica has strong antioxidant and hepatoprotective effects and accordingly may relieve liver harm caused by aflatoxin B1 induced hepatotoxicity in mice. Background Fruits and veggies are good beginnings of natural antioxidants for the human diet, incorporating many different antioxidant constituents include carotenoids, vitamins, flavonoids, other phenolic compounds, dietetic glutathione and endogenous metabolites, which provide protection against harmful free groups [ 1,2 ] . These antioxidants besides have been strongly associated with decreased hazard of chronic diseases, such as cardiovascular disease, malignant neoplastic disease, diabetes, Alzheimer s disease, cataracts and age-related functional diminution in add-on to other wellness benefits [ 3 ] . Cruciferous veggies, belong to household Cruciferae in specific of theBrassicagenus such as Brassica oleracea italica, Brassica oleracea botrytis, boodle and Bruxelless sprouts, have important malignant neoplastic disease preventative effects, as shown in epidemiological and carnal carcinogenesis surveies [ 4 ] . They contain significant measures of isothiocyanates ( largely in the signifier of their glucosinolate precursors ) some of which ( e.g. , sulforaphane or 4-methylsulfinylbutyl isothiocyanate ) are really powerful inducers of stage 2 enzymes [ 5 ] .Brassica oleraceaL. volt-ampere. italica ( Brassica oleracea italica ) is a good beginning of wellness advancing compounds since it besides contains a assortment of polyphenolics [ 6 ] . The malignant neoplastic disease protective belongingss of Brassica oleracea italica ingestion are most likely mediated through bioactive compounds that induce a assortment of physiologic maps including moving as direct or indirect antioxidants, m odulating enzymes and commanding programmed cell death and the cell rhythm [ 7 ] . Broccoli besides contains other protective components like beta-carotene, vitamin C and vitamin E, which can assist to cut down reactive O species, degree and prevent malignant neoplastic diseases [ 8 ] . Broccoli showed its antioxidant and cytoprotective efficaciousness against many diseases such as alzheimer s disease [ 9 ] , Parkinson s disease [ 10 ] , chest malignant neoplastic disease [ 11 ] , vesica malignant neoplastic disease [ 12 ] , prostate malignant neoplastic disease [ 13 ] , lung malignant neoplastic disease [ 14 ] , nephritic malignant neoplastic disease [ 15 ] , hepatic malignant neoplastic disease [ 16 ] , skin malignant neoplastic disease [ 17 ] , encephalon hurt [ 18 ] and cholestrol [ 19 ] . Ascorbic acid ( vitamin C ) is an negatron giver, and this belongings histories for all its known maps. As an negatron giver, vitamin C is a powerful water-soluble antioxidant in worlds. Antioxidant effects of vitamin C have been demonstrated in earlier surveies[ 20 ] . Vitamin C plays an of import physiological function in cells as a reduction agent and antioxidant, free extremist scavenger and enzyme cofactor. Glutathione and vitamin C show a strong functional mutualityin vivo. Vitamin C protects endothelial cells from oxidative emphasis by neutralizing the effects of oxidative species and diminishing blood cell-endothelial cell interactions, while glutathione modulates the oxidation-reduction belongingss of vitamin C in endothelial cells. Clinical surveies have revealed that vitamin C can change by reversal endothelial disfunction under different pathological conditions such as hypercholesteremia, high blood pressure, smoke, diabetes and coronary artery disease [ 21 ] .Aflatoxin B 1 ( AFB1 ) is a powerful hepatocarcinogen, which may play a major function in the etiology of human hepatic and extrahepatic carcinogenesis [ 22, 23 ] . An increased incidence of hepatocellular carcinoma has been associated with dietetic exposure to AFB1, peculiarly in population that is normally exposed to hepatitis B virus [ 24, 25 ] . The toxicity and carcinogenicity of AFB1 is thought to be straight linked to its bioactivation, ensuing in a extremely reactive AFB1 8, 9-epoxide ( AFBO ) . This bioactivation of AFB1 occurs chiefly by a microsomal cytochrome P450 ( CYP450 ) dependent epoxidation of the terminal furan ring of AFB1 and is responsible for adhering to cellular supermolecules such as DNA, RNA and other protein components [ 26 ] . Recent findings have demonstrated that oxidative harm is one of the underlining mechanisms for the aflatoxin B1 ( AFB1 ) -induced cytotoxicity and carcinogenicity [ 24 ] . An addition in the formation of reactive O species ( ROS ) was detected by Shenet Al. [ 26, 27 ] utilizing a fluorescent investigation, 2V,7V-dichlorofluorescin diacetate, in civilized rat hepatocytes following AFB1 exposure. These reactive O species ( ROS ) may assail soluble cell compounds every bit good as membranes, finally taking to the damage of cell operation and cytolysis [ 28 ] . Peroxidative amendss induced in the cell are encountered by luxuriant defence mechanisms, including enzymic and non enzymic antioxidants [ 29 ] . It has been implicated that oxidative emphasis following aflatoxin metamorphosis, together with hepatotoxicity or hepatocarcinogenesis was inhibited by the usage of food-associated antioxidants and/or free extremist scavengers [ 30, 31, 32, 33, 24 ] .

Discussion A figure of groundss suggest that oxidative harm caused by aflatoxin B1 ( AFB1 ) might be one of the mechanism behind aflatoxin B1 induced cell hurt and DNA harm, finally taking to carcinogenesis [ 43, 27 ] . AFB1 induced free extremist production or ROS production has been referred to as a possible ground for hepatotoxicity [ 44 ] . When ROS production overcomes the legion antioxidant barriers of defence it amendss a scope of cellular constructions and maps is produced. This procedure, known as oxidative emphasis, leads to pathologies such as coronary artery disease and malignant neoplastic disease, and finally to cell decease [ 45 ] . Lipid peroxidation ( LPO ) is one of the chief manifestation of oxidative harm initiated by ROS and it has been linked with altered membrane construction and enzyme inactivation. It is initiated by abstraction of H atom from the side concatenation of polyunsaturated fatty acids in the membrane [ 46 ] . Present information reveals that AFB1 disposal pr oduced pronounced oxidative impact as evidenced from important ( P lt ; 0.01 ) addition in LPO. The addition in LPO might consequences from increased production of free groups and lessening in antioxidant position. The oxidative emphasis observed in our survey is in conformity with the other studies where it has been implicated in AFB1 induced hepatotoxicity [ 47, 48, 49 ] .A In this survey intervention of animate beings with ethanolic infusion of Brassica oleracea italica ( EEB ) after 30 proceedingss of AFB1 disposal significantly reduced the AFB1 induced LPO ( Figure 1 ) by their ability to scavenge the free groups due to the presence of vitamin C, caretenoides and polyphenols etc in the Brassica oleracea italica infusion [ 50 ] . An of import function in the protection of tissues from the hurtful consequence of activated AFB1 is besides played by GSH and GST [ 51 ] . The enzymatic antioxidant defence systems are the natural defenders against lipid peroxidation. SOD, CAT and GPx enzymes are of import scavengers of superoxide ion and H peroxide. These enzymes prevent coevals of hydroxyl extremist and protect the cellular components from oxidative harm [ 52 ] . GPx is a cytoplasmatic and mitochondrial enzyme that detoxifies H2O2 in most cells. Glutathione-S-transferase ( GST ) is a household of the enzymes that catalyze the add-on of the tripeptide glutathione to endogenous and xenobiotic substrates, which have electrophilic functional groups. They play an of import function in detoxification and metamorphosis of many xenobiotic and endobiotic compounds. Superoxide dismutase is a really of import enzyme that maps as a cellular antioxidant. It is present in cell cytol and in chondriosome in order to keep a low concentration of superoxide anions. The important decrease in the activities of antioxidant enzymes ( GPx, GST, GR, SOD and CAT ) and non- enz ymatic antioxidant system ( GSH ) in aflatoxin treated mice liver ( group II ) as compared to the control group ( group I ) could be responsible for increased lipid peroxidation degrees observed during aflatoxin induced oxidative emphasis. Similar consequences have besides been reported antecedently for liver of mice [ 33 ] . GSH is a tripeptide containing cysteine that has a reactive -SH group with reductive authority. It can move as non enzymic antioxidant by direct interaction of -SH group with ROS or it can be involved in the enzymatic detoxification of ROS as a coenzyme [ 53 ] . GST catalyzes the junction of AFB1-8,9-epoxide with GSH to organize AFB1 -epoxide- GSH conjugates thereby diminishing the intracellular glutathione content [ 54 ] . This observation supports our findings where we observed a important diminution in degree of GSH ( Figure 2 ) and GST ( Table 1 ) in AFB1 induced animate beings. The Restoration of intracellular GSH contents and GST activity to normal degrees by Brassica oleracea italica infusion and ascorbic acid indicates that they play a critical function in extenuating AFB1 induced oxidative emphasis and subsequent harm to liver. Protein contents besides significantly decreased in aflatoxin treated mice liver. While groups which received ethanolic infusion of Brassica oleracea italica or ascorbic acid alongwith aflatoxin showed important addition in protein contents, this consequence is supported by old findings which demonstrated that aflatoxin lowers the protein contents [ 55 ] . It is already reported that Brassica oleracea italica is a good beginning of wellness advancing compounds since it contains many antioxidants such as vitamins, vitamin Es, caretenoids, polyphenolics and more specifically the compound glucoraphanin, which can metabolize to an anticancer substance sulforaphane [ 6 ] . In present survey the Restoration of GSH degree by broccoli infusion may be due to the polyphenolic antioxidants particularly flavonoids. Our findings is supported by the old surveies related to the protective consequence of antioxidants such as carotenoid, oltipraz, ebelsen against the cytotoxicity, hepatotoxicity and genotoxicity of aflatoxin B1 [ 56 ] . Antioxidants enzymes like GPx, GR, SOD and CAT form the first line of defence Against ROS and a lessening in their activities was observed with aflatoxin B1 disposal [ 49 ] . The above findings corroborates with our consequences where we observed a diminution in GPx, GR, SOD and CAT activities.A Selenium dependant GPx removes both H2O2 and lipid peroxides by catalysing the transition of lipid hydroperoxide to hydroxyl acids in the presence of GSH. The activity of GPx which is a component of GSH redox rhythm decreased during AFB1 disposal. This lessening in GPx activity may be due to the lessening in the handiness of substrate ( GSH ) and besides because of their change in their protein construction by ROS [ 29 ] . The increased intracellular GSH content following broccoli infusion and ascorbic acid intervention in several groups after aflatoxin disposal may trip GPx by forestalling the accretion of H2O2. The lessening in the degree of glutathione metabolising enzyme GR activity in AFB1 administered rats occurs as a consequence of reduced supply of reduced nico tinamide A dinucleotide phosphate ( NADPH ) for the transition of GSSG to GSH in the presence of GR. Under oxidative assault, NADP+ /NADPH ratio will exchange in favor of NADP+ , bespeaking lessening in the activity of enzymes [ 49 ] . Treatment with infusion of Brassica oleracea italica ( EEB ) and ascorbic acid ( Asc ) significantly increased the activity of GR ( Table 1 ) . This determination is besides supported by the work ofA Eberhardtet Al. ( 2005 ) [ 57 ] who reported the antioxidant capacity of Brassica oleracea italica on cellular oxidative emphasis. SOD is a household of metalloenzymes that is known to speed up the dismutation of endogenous cytotoxic superoxide groups to H2O2 which are hurtful to polyunsaturated fatty acids and structural protein of plasma membrane [ 58 ] . The H peroxide produced by SOD is farther removed by CAT. Decline in the activities of these enzymes after AFB1 disposal might be due to the inactivation of these enzymes ROS. Broccoli infusion increases the GSH position ensuing in the addition in SOD activity thereby forestalling the hurtful effects of superoxide groups. Therefore broccoli infusion indirectly influences the activities of SOD and CAT ( Table 1 ) . Histopathological analysis of liver samples shows vacuolar devolution of hepatocytes in aflatoxin treated liver of mice ( Figure 3b ) , while mice treated with aflatoxin and Brassica oleracea italica infusion at the same time showed kupffer
