Dark Chocolate Essay Example for Free

Dark Chocolate Essay (NaturalNews) Ongoing research shows that eating dark chocolate exerts beneficial effects throughout the whole body. High quality chocolate delivers disease-zapping antioxidants, lowers blood pressure and protects your heart and liver, all in one fell crunch. Chemistry Central Journal brings even more good news for chocolate lovers, stating that dark chocolate contains more flavanols and polyphenols than fruit juice. Cacao seeds are a Super Fruit providing nutritive value beyond that of their macronutrient composition, said Dr Debra Miller. Chocolate and Blood Pressure The important thing is that the antioxidants in dark chocolate can significantly reduce blood pressure in patients with hypertension. According to researchers from the University of Adelaide, flavanols promote vasodilation, which may consequently lower blood pressure. There have, however, been conflicting results as to the real-life effects of eating chocolate. Weve found that consumption can significantly, albeit modestly, reduce blood pressure for people with high blood pressure but not for people with normal blood pressure. added Dr Karin Ried, who is program manager and research fellow of the PHCRED (Primary Health Care Research Evaluation Development) program at The University of Adelaide. The analysis concluded that the pressure reduction caused by chocolate consumption was comparable to the effects of 30 minutes of daily physical activity. Chocolate and Cirrhosis There are also potential benefits for liver disease patients. Spanish scientists found that eating dark chocolate lowers blood pressure in the liver and reduces damage to the blood vessels of patients with cirrhosis. A study which was presented at the International Liver Congress 2010 divided 21 cirrhotic patients with end stage liver disease into two groups. The first group received liquid meal containing dark chocolate, while the participants in the second group were getting liquid meal with white chocolate devoid of anti-oxidant properties. As a result, the patients receiving dark chocolate experienced a noticeable reduction of post-prandial increase in blood pressure in the liver. one Square Is Enough. However, it is not necessary to eat huge quantities of chocolate in order to experience all the health benefits. In fact, just one small square a day may be enough to experience the health benefits chocolate is offering. A study performed in Germany that compared 19 357 individuals found that those who ate the most amount of chocolate (an average of 7. 5 grams a day) were at a 39% lower risk of developing a heart attack than people with the lowest (1. 7 grams) chocolate intakes. To put things into perspective, the six grams of difference are the equivalent of one small square of a typical 100g chocolate bar. Our hypothesis was that because chocolate appears to have a pronounced effect on blood pressure, therefore chocolate consumption would lower the risk of strokes and heart attacks, explains Dr Brian Buijsse from the German Institute of Human Nutrition, who led the research. Small amounts of chocolate may help to prevent heart disease, but only if it replaces other energy-dense food, such as snacks, in order to keep body weight stable.

Patient Refusal Of Treatment Nursing Essay

Patient Refusal Of Treatment Nursing Essay I dont want to be treated, Alice Nuvo said in the scenario 6. She is a woman who was diagnosed with pancreatic cancer and that has a very low percentage of survival for another year, even with the best treatment. Just give me something to control the pain and let me go home- she said. In this scenario we will talk about autonomy, which is typically defined as self-determination and refers to the ability of competent individuals to make decisions over their own lives. In order for autonomy to be meaningful, a competent individuals decisions should be respected even when those decisions conflict with what others believe to be reasonable. Over the last few decades, respect for autonomy has come to be recognized as a fundamental principle of Bioethics. In general, a patients autonomy should be respected even if the patient decides not to follow a doctors or health care teams advice. Respect for autonomy has helped to redefine the physician-patient relationship as patients have become more active participants in making health care decisions. Traditionally, the physician played a more paternalistic role in that he/she would largely decide for the patient what the best course of action would be. But now days the patient should not be coerced into making a health care decision, meaning that the patient should not be forced against his/her wishes into making a choice. The patients decision must be voluntary. The basic starting point for ethical analysis in health care, is the encounter between the patient and the health care professional. This relationship is shaped by the goals of that encounter, both the goals that health care professional has and the goals that the patient has. The goals of medicine, which guide the goals of all health care professionals, are: to prevent, cure, slow down or arrest the development of an illness; to stabilize a satisfactory condition; or to relieve the distressing symptoms of illness. It is important to note that these goals are more than simply seeking a cure, and are certainly not focused on seeking to preserve or prolong life at all costs. It is also important to recognize that it is not necessarily possible to meet all of these goals all of the time. The other person in the encounter is the patient, who also has her or his own goals, both health and broader goals in life, as well as values and preferences. Each person forms her or his own conception of what is a good life. This means each person has the freedom to act to put the choices that arise from that conception into effect. Everyone else must respect the space a person needs in which to do this. This is the basis of autonomy. However, autonomy is not an end in itself, but a means whereby a person takes responsibility for her or his own life. In health care, autonomy can be expressed in this way: the patient is the source of the health care professionals right to treat her or him. More specifically the patient has the right to choose to accept or refuse treatment that is offered or choose between different options. The important thing to remember is that the patient will consider her or his goals in life, will act upon her or his values and preferences as well as the medical facts in making such a decision, and all of these must be respected. In many situations the patients decision is not questioned. Decisions have been challenged when the choice does not seem reasonabl e to the health care professionals or others, generally it is challenged by questioning the competence of the patient, which we are not going to question in this particular case of Alice Nuvo. A patients decision to accept or refuse life-sustaining treatment needs to come out of a reflection on the usefulness and reasonableness of such treatment. Treatment has to be reasonable, this means that it has to be effective and that the benefits need to be in proportion to the burden for the patient of undergoing the treatment. There are two aspects of the refusal of life-sustaining treatment. The goals of medicine establish the purposes of treatment. It is not always possible to meet all of the goals, and at times may only be possible to relieve the distressing symptoms of illness. It is not a goal of medicine to prolong the dying process. The second aspect of any decision to forgo treatment is the patients right to choose whether or not to accept such treatment, even if the treatment has a reasonable chance of being effective. A person who is terminally ill is someone for whom there is no further curative treatment, like Alice Nuvo has no further CURATIVE treatment. Therefore, the only goal that it may be possible to meet is that of relieving symptoms. However, the point at which treatment is ceased and the decision made to forgo resuscitation varies with each patient. One person may wish to remain alive long enough to see a grandchild married. Another person may wish to spend the last weeks of life with close family members without suffering the debilitating side effects of chemotherapy. Id rather spend the remaining time with my husband and two daughters then die in the peace, instead of puking up my guts in some hospital Alice Nuvo said. After all this being said, the fact that refusal of any life-sustaining treatment is not to be equated with a slow, passive suicide, the person is not choosing to die. Rather she or he is choosing other goals, in line with her or his conception of a good life. In each case death is accepted as a foreseen, possible side effect of such a choice, but it is not directly chosen. Decisions regarding life-sustaining treatment are complex. Such decisions made by patients are based on a balancing of the benefits and burden of any such treatment and will include the goals, values and preferences that the patient has. But sometimes doctor thinks patient is making the wrong decision, how far should he go to try to persuade her or him to accept the treatment? Patient autonomy does not allow the health care provider to make the decision for the patient, but it does allow providers to educate the patient. It requires of health care providers that they respect patients by providing accurate and complete information that gives patient understanding of positive and negative sides of treatment.

The Warm and Cold Blooded Nature of Dinosaurs :: Anthropology Essays Paleontology Papers

The Warm and Cold Blooded Nature of Dinosaurs The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded. I will provide background information on the dinosaur that was discovered and what information it provides scientists. Until recently, scientists believed the chances of finding a fossilized dinosaur heart were extremely slim. The heart belonged to a 66 million year old dinosaur found in Harding County in Northwestern South Dakota. The dinosaur, found in 1993, weighed over 650 pounds and was 13 feet long. The dinosaur was in fairly good condition with the exception of the left side of the skeleton. The small, plant-eating Thescelosaurus, nicknamed ‘Willo’ has been acquired by the North Carolina Museum of Natural Sciences. Thescelosaurus was an ornithischian, or "bird-hipped," dinosaur that lived in the latter stage of the Cretaceous period. This was approximately 1 million years before the end of the dinosaur era. Native to North America, its range extended from the northern United States up into Canada. Since using the 3-D software to reveal Willo's heart, scientists have also used it to create 3-D images of the fossil's skull, and of remains from other dinosaurs in the museum's collection. (Fisher, Paul) A group of scientists from North Carolina and Oregon used medical technology to search an iron-stained concretion inside the specimen’s chest. With the assistance of imaging equipment and software, they were able to reconstruct 3-dimensional structures through the interior of the concretion. The images reveal a heart that was more like that of a bird or a mammal than those of reptiles, significantly adding to evidence suggesting that at least some dinosaurs had high metabolic rates. In addition, the heart appears to have been four chambered with a single aorta, which is most commonly found in mammals or birds.

Sport Utility Vehicles :: SUVs Transportation Automobiles Essays

Sport Utility Vehicles In recent years the market for SUVs, Sport Utility Vehicles, and pickup-trucks has increased significantly. In fact, â€Å"more than 40% of consumers say they are considering buying an SUV for their next vehicle, the highest of any segment,† (Halliday 1-2). As the name implies, Sport Utility Vehicles were originally intended as means of transportation in places where normal cars would not function well, such as off-road. Pickup-trucks were also designed for a practical purpose, hauling materials that would not normally fit in a car trunk. Has the dramatic increase in sales of SUVs lead to a dramatic increase in the number of people driving off-road? No. Has the dramatic increase in the sales of pickup-trucks lead to an increase in people hauling large objects? No. The majority of SUV and truck owners purchase their vehicles because they believe that they are safer. The question arises how safe are SUVs and trucks really? SUV and truck safety can be broken down into t wo categories, the safety of the driver of the SUV or truck and the safety of any other motorist who collides with an SUV or truck. What kinds of people would want to buy an SUV or a truck? Well the practical answer would be people who want to off-road or haul large equipment, but that is not the largest group of SUV and truck consumers. Most SUV owners buy SUVs because they feel as though they are more protected in case of an accident. This is a proven fact â€Å"SUVs, vans, and pickups appear to be more aggressive and may be more crashworthy than cars. Effects of pickups are most pronounced. Drivers in pickups face less risk of serious injury than car drivers,† (Toy / Hammitt 7-8). This is a very valid point. Force is equal to mass times acceleration. If a car and an SUV are traveling at a relatively similar speed and they collide, the vehicle with more mass, the SUV, will always win. This obsession with feeling safe is resulting in the size of SUVs and trucks reaching ridiculous proportions. The new Ford Excursion is too large to fit into many normal sized parking spaces. Every year trucks and SUVs get bigger in an effort to be the â€Å"safest† vehicle on the road.

The Afro-Cuban Struggle for Equality Essay -- Cuba Equality Racism Ess

The Afro-Cuban Struggle for Equality Introduction During the late nineteenth and early twentieth centuries, the island of Cuba was in the process of emerging from a Spanish colony to an independent nation. Freedom from Spain, however, was not the only struggle that Cuba was experiencing at this time. After having been oppressed by slavery for several centuries, Afro-Cubans, who had joined the fight for independence in large numbers, were demanding equality in Cuban society. Nevertheless, whites, especially in the elite, continued to initiate discriminatory practices against them. As a last resort, Afro-Cubans staged an armed protest in response to the outlawing of their political party in 1912. Although valiant, the attempt was nonetheless a failure because it did not succeed in establishing racial equality in Cuba. Rather, it tragically resulted in the massacre of thousands of Afro-Cuban protesters by Cuban whites. Discussion As was the case throughout the Americas, white racism against blacks and mulattos was deeply rooted in Cuban society. Prejudice and discrimination against Afro-Cubans continued to increase after the abolition of slavery in 1886. Whites, particularly those in the upper classes, viewed blacks and mulattos as belonging to an inferior race that was unworthy of the same rights and privileges that they themselves enjoyed in society. Education, entertainment, and employment were some of the areas in which Afro-Cubans suffered significant discrimination. They were often denied acceptance into private schools, given separate accommodations in theaters and other entertainment establishments, refused service by many restaurants, and were usually unable to obtain employment in professional and skille... ...test as a last resort to bring about its restoration. Nevertheless, it resulted in failure when Afro-Cubans were massacred by the thousands. Conclusion The massacre of 1912 demonstrated that there remained to be seen true racial equality in Cuba. Although the wars of independence had brought about some improvements in race relations, such as the fraternity shared between the races when fighting together against Spain, and the recognition of some Afro-Cubans as outstanding military leaders, the nation’s black and mulatto populations remained for the most part at the lower levels of society. Without politicians who would support their interests, Afro-Cubans would continue to be without equal opportunities in Cuba. Works Cited Helg, Aline.

Explain how multi agency teams work together to support speech, language and communication. Essay

There are a number of professionals that come into contact with each other if a child has needs with speech, language and communication and require support from different areas. E.g. a social worker, SEN Officer, teacher and parent can work together to improve the life of a child or young person. They may come together to discuss a plan that is best for the child to progress effectively. Each child may have different professionals to tailor their individual needs. The people with specialist knowledge and skills will support the people that work with them on a daily basis and have regular meetings to remove barriers of achievement, agree strategies, provide training and identify, and sometimes provide resources. SENCO have the correct paper work in place and ensure appointments are up to date, this will make it easy to monitor development. This will help to co-ordinate with professionals who work with the child. The LEA decides between the school and external support services on how to support the child’s development and may arrange the intervention of a school action plus level to be provided. It also has a parent partnership so parents can be heard and understood with their views taken into account. Every child matters is a programme that covers all children in the school age 0-19. It has been set up so that schools and parents work together to give very child the best chance on life. It has a shared database of children containing information of every child so that all multi agencies, schools, police and voluntary groups can ensure the welfare of each child and can be assessed.

Analysis on the Movie Instinct

Instinct –About A Mere Illusion One of the two main characters in this movie is Dr. Ethan Powell, an anthropologist. The study of primatology is present in this movie, because Dr. Powell is shown several times living with the mountain gorillas. He gains their trust by adapting to the way they live and interact. I think a little bit of cultural anthropology is also present because although he is studying primates, I believe they have a culture and Dr. Powell has adapted to their nature. The second important character in this movie is Dr.Theo Caulder, a psychologist. The first sub field of psychology that is present in this movie is cognitive psychology. We are introduced to Dr. Caulder while he is interviewing a patient who is delusional and tries to help her understand that she may be wrong. Another sub field of psychology presented is behavioural psychology. The inmates may not have acted the way that they did if it was not for the guards and Warden. Because of the excess cru elty, the inmates were brutalized and forced to re direct their negative energy to each other.I think psychoanalytic psychology is also present in this movie. When Dr. Powell is captured by the poachers, the Silverback tries to save him. Similarly when Peter, one of the inmates is being beaten, Dr. Powell steps in to help him like when the Silverback did. I think this was unconscious motivation from the previous event. Dr. Ethan Powell and Dr. Theo Caulder have very contrastive ways of conducting and obtaining their research. Dr. Powell adapted into the forest to live with the mountain gorillas to observe rituals and group behaviour.When he realized they were uncomfortable with the camera, he left it behind and started to see them for who they were for the first time. He was â€Å"a man living with animals† because the gorillas reached across and accepted him, a human. He started to care for the gorillas and they eventually became his family. Dr. Caulder on the other hand tri es to understand the feelings and thoughts of his patients through a series of interviews. He tries to figure out why his patients (Dr. Powell and other inmates) behave the way they do and and what causes them to act that way, their mental process.Dr. Caulder soon changes the way he interviews Dr. Powell by accommodating him in environments that are closer to him or that he would possibly feel safer in. For example, he takes Dr. Powell to the zoo to see some on the gorillas and then asks the guards to leave because he realizes it was making Dr. Powell feel uncomfortable. Frankincense, making both Dr. Powell's and Dr. Caulder' way of conducting research similar. I think humans are truly not in control of their own lives. If we were, everyone would be doing whatever they wanted to do and that would be â€Å"savage. Life is a game and sometimes we need to be taught how to play properly by a simple example of humanity. Dr. Powell proclaimed that you would find more violence in the city in one day then you ever would in the the forest and I agree. Humans are the only species that kill each other for reasons other than survival. I believe that control is merely an illusion that we like to believe we have. In one of Dr. Caulder's sessions with Ethan, the guards are asked to leave and soon Dr. Caulder is held captive by Ethan and is demanded to write down what he has lost. Dr.Caulder answers â€Å"control† but Ethan says no and asks a few more times. Finally realizing what Ethan is talking about, Dr. Caulder writes down â€Å"illusion. †Ethan then explains how we only have the illusion of having power and control but none of it is actually there to begin with. Another example is when Dacks, on the of the guards, distributes the cards to determine who goes outside that day for a half hour. He always gives the Ace of diamonds to a weaker inmate so that the bully inmate can steal it by scaring them and getting the time outside every single day.The guards d etermine who gets to go outside everyday and all the weaker inmates have to give up their chance because they are to scared to fight back. Thus, diverting all their negative energy towards each other and leaving all the guards at peace. Throughout the movie, Theo is asked by Ethan if he is really free? I think Ethan is referring to when he was living with the mountain gorillas. They were living at peace and harmony and that is what felt like freedom to him. They never fought with each other and only took what they needed, preserving the environment. He was asking Dr.Caulder if living the way he was, was what he considered to be his freedom. I think that the movie's focus on true nature of human existence was excellent. It portrays us just like we are in real life. We are arrogant and have a great sense of entitlement. Ethan has divided humans into two groups. There are the â€Å"Takers and the Tribesmen,† also referred to as the â€Å"Civilized and the Pre-Civilized. † The Takers in the movie are the Guards, the Poachers, and the Warden (all forms of authority). They are dominant and have a God-like syndrome thinking they are superior to everyone else including other humans and animals.The Tribesmen in the movie are Dr. Ethan Powell, the gorillas and other inmates. They could be living in peace if the influence of the guards was limited. For example, Dr. Caulder changed the way the person was selected for the half hour of time outside. â€Å"Everyone goes outside,† is what everybody chanted together forming a revolution. Dr. Theo Caulder is the exception. He was first perceived as a Taker. In the beginning he is shown to only care about his career and that is why he takes up Dr. Ethan Powell's case in the first place, to further his career.His superior believes he can write a book and become a famous psychologist. But soon enough Ethan is able to change Dr. Caulder's mind and teaches him how to live. He starts to believe that he can actual ly get Ethan out of prison and prove that he has not turned into an animal, putting Dr. Caulder into the category of Tribesmen. This encourages me to believe that there is still hope for us to change our lifestyle and the way we think. It shows there is still hope to make us all less savage and make our progress as humans more positive. By. Tanvi Patel
