Abstract

Of the many illnesses and diseases known to humanity, few are more frightening or deadly than cancer. Lung cancer is of especially great concern, because it kills more people worldwide than any other form of cancer. It is a silent killer, often going undetected until it is too late, because it often has no symptoms and cannot be screened for readily. Despite research efforts, no cure has been found for the disease and treatments are effective in a relatively small number of cases. However, some progress has been made in preventing lung cancer, especially by reducing exposure to cigarette smoke, asbestos, radon, and other carcinogens in the environment. Other causes and factors of lung cancer demand more research, and prevention efforts should be promoted.

Lung Cancer: What Is It And Is There A Cure In Sight?
Incidence and Mortality Lung cancer is one of the most significant medical problems in the U.S. and around the world, because it is the cause of more deaths nationally and globally than any other form of cancer (Centers for Disease Control, 2011, a; Clément-Duchêne & Wakelee, 2010). According to the Centers for Disease Control (2011, a), 14% of all cancer diagnoses in the United States in 2007 were lung cancer, and 28% of all cancer deaths in the same year were caused by lung cancer. These high rates are actually lower than they have been in previous years as the rate of lung cancer and resulting deaths have been declining with the reduction in smoking in the United States (Centers for Disease Control, 2011, a). Moreover, rates of smoking remain much higher globally than they are in the U.S., and lung cancer rates are accordingly even higher in many

...Keep simple and polite! Good morning teachers and friends, I, Ahmad Khairi Hafiz as the President of the Environment Club would like to talk about”How to Protect the Environment” First of all, each one of us can start by not littering. We should throw our rubbish into the rubbish bin instead of anywhere we like. Once I went strolling at a park nearby my house but was dissapointed at the sight of rubbish.I saw many empty cans and plastic wrappers lying around.They do not only spoil the beautiful park but they are the best breeding place for aedes mosquitoes. Another way of protecting our environment is by keeping our rivers clean. We can play our role by not throwing rubbish into the rivers. Meanwhile the factories can stop dumping their toxic waste into them. Plastic wrappers which made up 80 percent of the rubbish can endanger the fish and other aquatic lives while toxic waste can kill them. We, human will consequently suffer as we rely on the rivers for food and water. Moreover, farmers should avoid open burning in their farming practice because it polutes the air.Open burning can lead to haze which contains poisonous gases such as carbon dioxide and sulphur dioxide. These gases can cause many serious diseases. Children who breathe the polluted air may suffer from asthma and some people may even suffer from rashes and eye-diseases. Finally, we can practice the 3R; Reuse, Reduce and Recycle. Every household should aim at reducing the amount of rubbish thrown.To...

...another they are sought out by all of us. Somewhere inside we all seek balanced happy lives and so we seek that which will grant us health and joy. This article is about Turmeric, one of the planet’s great healers. This healer is not obscured in some esoterica and not distanced by a cosmic price tag. As usual with great healers, it is very close to you and readily accessible, in fact, it is probably in your house right now, though it may be hard to believe that such a common item is one of the world’s best all around herbs. The core of its worldwide ubiquity is found while walking through the bazaars of India where you are bound to find a masala wallah, a spice seller, with mounds of Turmeric that he is selling by the kilo. It is a great sight in the midst of mountains of clove buds, black pepper fruits, coriander seeds, cinnamon bark, cardamom pods and all these marvelous colorful spices that the world has loved since Silk Road days. Ayurveda is as full of commonsense as it is humming of the mystical and so, especially since it is an oral tradition, it is with the common people of India, like the spice sellers and the village mothers, that many traditions of herbal knowledge are learned and passed from elder to child for countless generations. In this way the ability of Turmeric is proven and its legacy grows. I have learned so much about ‘common’ herbs from ‘common’ people that I could never have learned elsewhere, a fact predicted by Paracelcus who in 1493 wrote: “The physician...

Gleevec: a Crushing Blow to Cancer

...drug for cancer research. Created by the rational drug design model, Gleevec targets the tyrosine kinase enzyme in CML patients.[10] By targeting and binding to the active sites of the cancerous cells, Gleevec denaturizes them, preventing the spread of the disease.[10] Gleevec has been FDA approved to be administered to patients diagnosed with chronic myelogenous leukemia and also patients with gastrointestinal stromal tumors.[6] Although, this treatment has also been proved to aid in other fields of medicine, ranging from treating other types of cancers to delaying tumor growth to therapy for diabetes and even to cancer treatment in pets.[5,6,8,9] However, for Gleevec to have been made other cell targeted drugs had to be made before it. And just as those drugs paved the way for Gleevec, Gleevec is paving the way for even more cancer treatments to be made. Introduction and Background The official war on cancer began when President Richard Nixon declared that this was the next big thing in the history of the United States. He compared the battle and potential cure of cancer to the process of landing on the moon. However, the battle against cancer has proved to be much more difficult. But there is progress being made. In 2003, 556,902 people in the United States died from cancer.[11] However, in 2002, 557,271 people in the United States died from cancer.[11] Even though the difference of deaths was not that great, this was still a giant step in the war on cancer.

Sample Report

...A survey was conducted amongst ______ students to get their insights on smoking and also their personal experiences with it. We divided the questionnaire for smokers and non-smokers. We managed to get a total of 50 participants in which 60% were non-smokers and 40% were smokers. The questions regarding smoking facts were answered by both sides. Both smokers and non-smokers seem to have just a slight understanding on what smoking really does to the body and to those around them. Based on the findings, we recommend that students be exposed to the real dangers of smoking. We suggest exhibitions, competitions, talks or maybe even a health class.

Summary of Drinking, a Love Story

...Part I: A. Introduction: Drinking, A Love Story, Written by Caroline Knapp: Is an insider’s story about fighting the battle of alcoholism and addiction, victoriously winning sobriety. Caroline Knapp fought her addiction for 20 years before becoming sober. “The Drink” as she called it, was her true love. The most beloved form being a good crisp dry white wine, but any form would do. She fell in love with alcohol at a young age and loved everything about it. The smell, the sound of a cork being pulled from a bottle, the cold liquid anesthesia running down the back of her throat after a long day at the office, the routine of drinking, but most of all she loved the way alcohol made her feel. Alcohol was the one thing for a very long time in Caroline’s life that she could depend on for temporary mental relief from whatever stressful or anxious thoughts she had. The effect of alcohol bringing a sense of calm and relaxation with every sip, it was her fuel to gain ultimate control of her thoughts and feelings for many, many years. She grew up in a privileged household with noted Harvard Psychiatrist, Peter Knapp, for a father and an abstract artist as a mother. From the outside, a picturesque family, on the inside a lonely and often emotionally terrifying place. Caroline refers to her relationship with her father often throughout the book, stating that at times she felt that he could “see through her” with his ambiguously vague questions and how this made her feel insecure and...

...One side of the argument is Pro-Choice, this is the side that is for abortion. This side believes each woman should have the choice to do what they want with their body, this thought process is what spurned the Roe vs. Wade case. Pro-Choice focuses strictly on the women who is pregnant. The idea that it is their body is a valid point, the idea that not all pregnancies are planned or even wanted is another point that the Pro-Choice movement will argue to defend their side of this abortion debate. Pro-Choice feels that the women’s civil rights are being violated by not having the choice to decide for themselves. Pro-Life side, one that feels that every life is a miracle and deserves the chance to live. This side stays on the course that all lives matter and deserve the chance to live.

Patho Chap 1

...Chapter 1 Introduction to Pathophysiology Lee-Ellen C. Copstead Key Questions • What is pathophysiology? • How are etiology and pathogenesis used to predict clinical manifestations and response to therapy? • How are normal and abnormal physiologic parameters defined? • What general factors affect the expression of disease in a particular person? • What kinds of information about disease can be gained through understanding concepts of epidemiology? http://evolve.elsevier.com/Copstead/ • Review Questions and Answers • Glossary (with audio pronunciations for selected terms) • Animations • Case Studies • Key Points Review Pathophysiology derives from the intersection of two older, related disciplines: pathology (from pathos, suffering) and physiology (from physis, nature). Pathology is the study and diagnosis of disease through examination of organs, tissues, cells, and bodily fluids. Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Together, as pathophysiology, the term refers to the study of abnormalities in physiologic functioning of living beings. Pathophysiology seeks to reveal physiologic responses of an organism to disruptions in its internal or external environment. Because humans exhibit considerable diversity, healthy structure and function are not precisely the same in any two individuals. However, discovering the common and expected responses to abnormalities in physiologic functioning is useful, and it...

Quitters Inc. by Stephen King (published in Night Shift, 1978) Quitters Inc. Worksheet ©2008, T. Orman “Quitters Inc.” by Stephen King NOTE to TEACHER: This short story is appropriate for high school students (grades 10-12). It contains strong language that may not be appropriate for all students, so please use your own discretion. I use the movie “Cat’s Eye” as a companion to this story because the first story in the movie is based on “Quitters Inc.” Two differences: Dick Morrison’s son is a daughter in the movie (played by Drew Barrymore) and a cat is used for the “rabbit room.” We also read “The Contents of the Dead Man’s Pocket” by Jack Finney. If you choose to show the entire movie “Cat’s Eye,” the second story is called “The Ledge.” It is not similar in theme, but you could talk about the similarities as characters from both must go out on a ledge of a tall building. “The Ledge” story (from King’s Night Shift collection) does contain profanity/ language.
