Understanding omega-3’s Essay Example for Free

Understanding omega-3’s Essay To-date, many studies have been conducted to validate and understand the effect of omega-3’s in primary and secondary prevention of cardiovascular diseases. Omega-3’s have attracted attention as potential triglyceride lowering and cardioprotective agents. They are a special group of polyunsaturated fatty acids found abundantly in marine sources (fatty fish) as eicosapentaenoic acid (EPA) and docohexaenoic acid (DHA), and in nuts, seeds and vegetable oils as ÃŽ ±-linolenic acid (ALA). The delta-6-desaturase enzyme in vivo converts ÃŽ ±-linolenic acid into EPA and subsequently to DHA. Further metabolism of these products yields eicosanoids, the subject of interest. Eicosanoids (thromboxane, leukotrienes, prostaglandins) derived from omega-3’s have an anti-inflammatory and anti-aggretory effect. These properties account for the cardioprotective effects of omega-3’s since inflammation is one of the basic factors behind atheroma formation and plaque rupture. Studies have confirmed the dietary intake of omega-3’s to be inversely proportional to the inflammatory markers C-reactive protein, IL-6, E-selectin, soluble intercellular adhesion molecule 1, and soluble vascular cell adhesion molecule 1. Another study revealed an inverse relationship between EPA+DHA intake and soluble tumor necrosis factors. Omega-3 consumption has been shown to be inversely proportional to CVD, especially sudden cardiac death. The reduction of sudden cardiac death in people who consumed fish once a week was more (52%) than those who ate fish less than once a month. However, no relationship between omega-3 consumption and non-sudden death, myocardial infarction, or CVD mortality has yet been established. Although studies have been focused on the effects of EPA+DHA, the 4 prospective randomized trials discussed in the article suggest that the effect of ALA is not much different. However, further studies need to be conducted to verify the details in metabolism of ALA to eicosanoids. This knowledge may be important in knowing the extent and limitations of the process, and the limiting factors if any. Use of omega-3 has not been reported to cause any life-threatening illnesses or deaths. However, some gastrointestinal problems have been reported in a minute fraction of subjects. Presence of traces of mercury or methyl mercury in fish poses risk of mercury poisoning. However, while the FDA recommends pregnant women, nursing mothers and young children to avoid eating fish with high mercury content, it allows adults one serving (7 oz. ) per week consumption of fish containing 1ppm mercury. Some studies suggest role of ALA in prostrate cancer. Although such a link has not fully been established, it is safer to chose fish oil when implementing omega-3 supplementation in men. The American Heart Association recommends that the patients without known CVD should maintain a diet rich in ALA and eat a variety of fish twice a week. Patients with known CVD should consume at least 1 g/d EPA+DHA (3 g/d of fish oil) (Table III). The graph in Figure 3 shows a marked decrease in the percentage of energy the industrial society is getting from omega-3’s since the past century. The sudden surge in the use of harmful trans fats and the omega-6’s can be seen as the reason to the increase in heart diseases and sudden cardiac deaths during this period. This study has established the importance of omega-3’s from fish and vegetable oils in diet for everyone who wishes to live a normal, healthy life. Further studies need to be conducted to account for the effects of long term use and minimum threshold doses of EPA+DHA and the extent of metabolism of ALA and its role in prostrate cancer. However, knowledge from this article has made me stauncher in the use of fish at least once a week, since I have a family history of CVD.

Tales of Ise and The Tosa Diary Essay -- Literary Analysis

As seen in examples of monogatari such as Tales of Ise or nikki with The Tosa Diary, poetry is a very much used tool in the writings. While other examples of the two writing styles use poetry, these two examples best demonstrate the breaks in the writing style changes from a narrative and turns into something that takes on a more personal voice when it clearly goes into its poetic style. These poems are made to compliment the setting, such as in a poem credited to the former governor in The Tosa Diary where there is a description of the waves as they illustrate the governor’s sadness as he leaves Kyoto (83). Another point seen from this poem is that the governor is meant to be very good at constructing his poems and with it comes an example of a good poem as opposed to something that a commoner would have to write. Likewise, in the tenth of the Tales of Ise there are poems describing the love a man has for a woman while he is also comparing the physical setting, such as the mo untains. There are comparisons to Mt. Fuji and Mt. Utsu while they represent the waiting for his love or the beautiful vision that the man sees in his dreams with his love respectively (75-6). Such images of the scenery as seen alongside the desires or longing of those who write the poems are examples of how the poems are used to strengthen the narrative prose. Without the poems, the narrative prose in either the monogatari or the nikki would simply be a story and the significance would be lessened as there would not be the personal impact emanating from the characters and their feelings since a reader would only be able to read the description of the events and not get a feel of the thoughts from any of the characters. In the very deep illustrations of the... ...d to be a woman in the company of the boat. The significance lies in the possibility that with the different types of poetry in the narrative, the governor presents examples of the types of poems that should be written by different people coming from different classes. Looking back at the narratives and the significance of the poems in them is that many of the poems are inspired by nature around the authors. Also, the poems provide more of the voice of the authors instead of just the voice of the narrator and helps present the emotional tones of the characters in the narratives to the reader so that there can be more of a connection to it when it is being read. The poems make for a simple addition to the narrative and allows for a much more meaningful experience for a reader and makes for a much more engrossing story, thus adding to the to experience as a whole.

My role model Essay

To me a role model is someone in my life that has influenced me in a positive way. They help shape the way I am in the present and what I am going to be in the future. They are some one that I can look forward for advice in a tough situation and I know that they will give me advices with wisdom. They will never judge me on my past but only look to help because they really do care about me. Some one who I never feel awkward talking to about my problems because I know that it will not change their view of me and they will not reveal any information about me to other unrelated person or someone who are nosey. A role model should be sincere and not out for there own good but the good of others. I think that they should be older then I am because they need to have more experience then I do and need to have a deeper insight. It would be pointless to have a role model who knows less then me. Read more: My role model essay But apart from my parents, , teachers or very best friends like Brian Lee really do care about me a lot, there is nobody should be deserved to have a talk about, or can drag my attraction, or makes me change my personality and reach more achievements. I don’t have a real one honestly, but I would be searching for him or her! ( You must feel surprised that why do I write such a short paragraph this timeï Å )

Market Failure And The Implications For Public Policy

When discussing the concept of Market Failure and the implications for Public Policy, the correlation, between the two is directly related to government intervention on market efficiency. Market Failure is discussed in the context of Pareto efficiency in the Free Market. Certain conditions must be met or Market Failures are inevitable and the government must intervene to correct the market. The first fundamental theorem of welfare economics asserts that under certain conditions which makes markets not Pareto efficient results in Market Failure (Stiglitz, 2000, p. 77). The conditions of market failure results when marginal cost (MC) does not equal marginal benefit (MB) and neither equals price (P), to reach equilibrium MC=MB=P and the market is Pareto efficient. The conditions under which there is not Pareto efficiency in the market and results in Market Failure are; failure of competition, public goods, externalities, incomplete markets, information failure, unemployment, inflation and disequilibrium (Aikins, 2015). If any of these conditions exist in the market, it provides the justification for government to address the failures through policies designed to reach Pareto efficiency. Pareto efficiency or Pareto optimal is defined as, to have resource allocation that have the property that no one can be made better off without someone being made worse off. Pareto efficiency in free markets incorporates involvement where Government is expected to protect citizens andShow MoreRelatedThe Kyoto Protocol Extension Is Worthwhile859 Words   |  4 Pagesinternational policy coordination by multilateral agreement is indispensable.
