The Effects of Caffeine on the Human Body

How does Caffeine affect the human body? Caffeine is the world’s most popular drug (Spiller, 1998), and can be found in over 60 species of plants throughout the world. Consumption of caffeine comes from cola, coffee, cocoa, tea, some medications and so much more. In this paper I will describe the effects of caffeine on the human body, from the health risks to how it can help your body; here are just some of the ways caffeine affects the human body both physically and psychologically.First of all, caffeine has been shown to lead to a loss of minerals found in bones, which eventually will cause osteoporosis, a disease that is characterized by very weak and brittle bones (Liddell, 2011). According to Spiller (1998), â€Å"caffeine intake equivalent to 2 or more cups a day was associated with a significantly increased hip fracture risk in woman† (p. 351). This is because caffeine decreases the ability of your body to absorb calcium by a small amount.To maintain a proper bon e density and drink caffeine regularly, it is important to â€Å"aim for three or four daily servings of calcium-rich foods such as milk, cheese and yogurt† (Liddell, 2011). Caffeine has many Psychological symptoms linked to it as well, such as addiction because caffeine is labeled as a stimulant so overtime people can become addicted to it (Martinez, 2010). Surprisingly you can become physically dependent on caffeine with only taking in doses as low as 100 mg a day (Gaskins, 1998), this is equivalent to 1 cup of coffee or 2 sodas!Also just like any other drug you can become addicted to, â€Å"people who are addicted to caffeine will experience withdrawal symptoms when they don't have enough in their system† Running head: Caffeine and the human body (Martinez, 2010). Other psychological symptoms that correlate to excessive caffeine ingestion are increased anxiety for those who already have anxiety and sleep disorders such as insomnia. On the other hand caffeine is not all bad for the human body, it has been shown to protect against Parkinson’s disease and depression, as well as preventing cognitive decline in elderly women (Anitei, 2007).Also evidence suggests that consuming moderate amounts of caffeine could help prevent diabetes, certain cancers and liver disease (Bartlett, 2011). Another way caffeine is beneficial is because it helps athletes significantly improve their endurance during explosive exercises such as sprinting or jumping. According to Bartlett (2011), â€Å"Consuming between 140 to 400 mg of caffeine before exercising can increase your endurance and overall exercise performance. † Overall, caffeine is the most popular drug and can be both harmful and beneficial to the human body.It can make your bones brittle, but it can also help boost your metabolism and fight certain diseases. Caffeine just like most things is good in moderation, and as long as you make sure to get enough calcium and nutrients it should have no l asting effects on your body.References Anitei, S. A. (2007).

Importance of Literature Essay

Literature is the foundation of life. It places an emphasis on many topics from human tragedies to tales of the ever-popular search for love. While it is physically written in words, these words come alive in the imagination of the mind, and its ability to comprehend the complexity or simplicity of the text. Literature enables people to see through the lenses of others, and sometimes even inanimate objects; therefore, it becomes a looking glass into the world as others view it. It is a journey that is inscribed in pages, and powered by the imagination of the reader. Ultimately, literature has provided a gateway to teach the reader about life experiences from even the saddest stories to the most joyful ones that will touch their hearts. From a very young age, many are exposed to literature in the most stripped down form: picture books and simple texts that are mainly for the sole purpose of teaching the alphabet etc. Although these are not nearly as complex as an 800-page sci-fi novel, it is the first step that many take towards the literary world. Progressively, as people grow older, they explore other genres of books, ones that propel them towards curiosity of the subject, and the overall book. Reading and being given the keys to the literature world prepares individuals from an early age to discover the true importance of literature: being able to comprehend and understand situations from many perspectives. Physically speaking, it is impossible to be someone else. It is impossible to switch bodies with another human being, and it is impossible to completely understand the complexity of their world. Literature, as an alternative, is the closest thing the world has to being able to understand another person whole-heartedly. For stance, a novel about a treacherous war, written in the perspective of a soldier, allows the reader to envision their memories, their pain, and their emotions without actually being that person. Consequently, literature can act as a time machine, enabling individuals to go into a specific time period of the story, into the mind and soul of the protagonist. With the ability to see the world with a pair of fresh eyes, it triggers the reader to reflect upon their own lives. Reading a material that is relatable to the reader may teach them morals and encourage them to practice good judgement. This can be proven through public school systems, where the books that are emphasized the most tend to have a moral-teaching purpose behind the story. An example would be William Shakespeare’s stories, where each one is meant to be reflective of human nature – both the good and bad. Consequently, this can promote better judgement of situations, so the reader does not find themselves in the same circumstances as perhaps those in the fiction world. Henceforth, literature is proven to not only be reflective of life, but it can also be used as a guide for the reader to follow and practice good judgement from. The world today is ever-changing. Never before has life been so chaotic and challenging for all. Life before literature was practical and predictable, but in present day, literature has expanded into countless libraries and into the minds of many as the gateway for comprehension and curiosity of the human mind and the world around them. Literature is of great importance and is studied upon as it provides the ability to connect human relationships, and define what is right and what is wrong. Therefore, words are alive more than ever before.

Percy Julian Biography

WHENEVER PERCY JULIAN TOLD his friends about his life, and how he had overcome all the obstacles from his beginning as the grandson of a slave, born â€Å"at the corner of Jeff Davis Avenue and South Oak Street in Montgomery, Alabama, the Capital in the cradle of the confederacy,†1 to scientist, inventor, business leader, humanist, protagonist of human rights, he liked to illustrate this long arduous climb by Donald Adams' The Seventh Fold:My dear friends, who daily climb uncertain hills in the countries of their minds, hills that have to do with the future of our country and of our children, may I humbly submit to you, the only thing that has enabled me to keep doing the creative work, was the constant determination: Take heart! Go farther on! 2 This imperative, go on! , characterizes not only his life but his research, where each answer created at least two new questions and led to the exponential growth of science as Percy experienced it in his lifetime. With this growth, h e later realized the concomitant responsibility and questions of ethics.Percy Julian was born on April 11, 1899, the oldest of six children of James Sumner Julian, a railway mail clerk, and his wife, Elizabeth Lena Adams. Since 1976 his birthday has been a holiday for the Village of Oak Park, a fashionable suburb of Chicago where the Julian family has resided since 1950, initially under precarious conditions (the Julian home, the first in the neighborhood to be owned by a black family, was the victim of arsonists on Thanksgiving Day, 1950, and the target of a dynamite bomb on June 12, 1951), and where other famous people, such as Ernest Hemingway and Frank Lloyd Wright, had their residences.Because Percy's father was a federal employee, the family held a higher status than most blacks of that day. This advantage, and the fact that his well-read father had a great love for mathematics and philosophy, helped him on the way to a formal education. Clearly, his must have been â€Å"a mi nd forever voyaging through strange seas of thought† (Wordsworth), or â€Å"a restless curiosity about things which he cannot understand† (Pascal), but the cultural and, above all, religious tradition in his family provided not only a epository of substantive values, but also a coding device for new ideas and achievements. That â€Å"the fear of the Lord is the beginning of all practical wisdom† was taught him, and not in Latin, by his revered paternal great-grandfather. My children and my friends all know him as Grandpa Cabe because they've heard me speak about him so many times. My great-grandfather, with the rest of us that day, was singing in the cotton field, where we children, particularly Dr.James Julian, my next brother, and I were sent to my grandfather's farm to work during the summer. We were singing on that day a beautiful spiritual, â€Å"There is a balm in Gilead to make the wounded whole. There is a balm in Gilead to heal the sin-sick soul. † â€Å"Grandpa Cabe,† I asked, â€Å"what's a balm in Gilead? † â€Å"Well, Sonny, you see, Gilead was a famous town in Israel for the manufacture of salves to heal wounds and sores,† he told me. â€Å"And they called these salves balms.Now one day Jeremiah was having a hard time trying to lead his people the right way. Everything was going wrong for Jeremiah, and he cried out in anguish, ‘Is there no balm in Gilead? ‘ You see, what he was saying was, ‘Ain't there no way out? ‘ I want you to know that, Sonny, because I believe there is always a way out. † It was then that I made my vow–that I would forever fight to keep hope alive because there is always a way out . . . . His optimism was one of the most pertinent lessons I learned as a youngster. Next t

Reflection in this connected world Essay Example | Topics and Well Written Essays - 500 words - 214

Reflection in this connected world - Essay Example People are able to chat and get instant feedback from their friends and relatives. However, technology poses some challenges to the society. The youth and adolescent are more affected as they are obsessed with computers and spend most of their time socializing and interacting with friends. They fail to manage their time effectively and the outcome is that they have nothing constructive to show at the end of the day. They are so attracted to social media that they abandon other forms of recreation like sports, mountain climbing, and creative arts. To curb this, college students should participate in the various activities provided by their schools like joining clubs and music festivals. By doing this, they create an opportunity to have face-to-face communication with the other students. Moreover, they can learn from each other experiences. For example, while in college I was taught on the basics of reading and understanding poems and the different types of poems but in college I was m ade to understand the purpose of the poem and the deeper meaning of it. Human beings need to take time and reflect on their lives and it is important to have some reflection in this connected world. For example, when in college, I used to wonder why my parents were so strict on me. I had to borrow permission before leaving the house and had to come back to the house by latest 6pm. I now know through reflection that they had a good reason for being tough on me. They wanted a responsible and disciplined daughter who could take charge and be accountable for everything she did. According to Fr. Nicholas, imagination is a process of going deeper to the depth of reality to recreate it. It is possible to imagine through the mind different sensations and images. While sending information through the different social media platforms, people receive information instantly and it is spread very fast without reflecting about the message.

Human Behaviour Essay Example | Topics and Well Written Essays - 1000 words

Human Behaviour - Essay Example One might ant to cook in order to appease hunger or to gain compliments from a spouse or to save money which would have been spent ordering food. In keeping with this cause-effect relationship, it does seem very easy to advocate that yes, we only do what we want to do. There is a complication however, which might also be considered an exception; fear. One may also do an act out of fear of the consequences if it were not done. For instance, an all too common phenomenon is thousands of people trudging to their workplaces daily out of fear of being fired or the fear of their wages being cut, or fear of awaiting bills. One may cook at home, continuing from an above example, also out of fear of extra calories or germs that outside food may contain. In such cases, strictly speaking, the individual does not want to act, but does so, since not performing the act would result in an unpleasant situation. Another consideration when attempting to figure whether we do only what we want to do, is the conflict between rationale and emotion. As Hume states, "nothing is more usual in philosophy, and even in common life, than to talk of the combat of passion and reason." The concept of what one wants to do then, would fit into the realm of passion or emotion rather than logic or reason. Hume emphasizes that reason alone can never be a motive to any action, nor can it oppose action in the direction of the will. In fact, reason is simply the discovery of the link between a driving emotion and its eventual desired consequences. (Hume, 1882) It is the knowledge of the fact that a particular thing is desired and will be achieved if acted upon in a particular manner. Thus, if reason figures only as a connection and not a cause of action, and emotions translate as 'want to do', it is easily concluded that eventually we only do what we want to do. In any case, whatever the source of action, the individual's primary concern is a selfish one. Whether an action is performed to create a pleasant consequence or to avoid an unpleasant situation, the basic driving force is a self-centered one. This brings us to the second part of the essay - whether there exist any natural virtues, which do not depend upon consequences or convenience, but yet instigate one to act in a particular manner. Strict empirical scientists would say no; it does not make logical sense for people to utilize their energies and resources without any benefit. Furthermore, it goes contrary to the survival instinct which pushes one to behave so as to obtain maximum advantages. Added, such behaviour, which social scientists now recognize as altruism, if engaged in often enough and by too many people, would completely overhaul the wheels of societies and economies that are governed by gain oriented cause-effect relationships. James Fieser emphasizes that natural virtues, (which include benevolence, meekness, charity and generosity) "are instinctive character traits of the agent which give rise to passions which in turn motivate the will to action." (Fieser, 1997) Artificial virtues, which are learnt or developed include justice, keeping promises, allegiance and chastity, and are evident to different degrees in different people, as Hume professes. Since natural virtues are instinctive, they would also be common to all

Networking Activity - Coursework Example One lesson touches on the importance of employees to an organization. I learnt that employees play a central role in the success of an organization. Therefore, there is a need of introducing proper motivational policies aimed at making these employees to be efficient in their work. The most surprising lesson is that high salaries are not a motivating factor, however, lack of good pay, may be a de-motivator. Therefore, the best motivating policies are the ones that touch on satisfying the interests of employees, and this includes good working conditions, chances of promotion, and provisions for vacations. Based on my conversation with Tawni Cranz, this networking activity was a success. This is mostly because to make a new friend on her, and also learn on some issues touching on human resource management. This is an important contact that I made, because in future, she may advice me on how to get a good

Political Sponsering of Ngos Essay Example for Free

Political Sponsering of Ngos Essay Greenpeace and green political parties are united in their position against nuclear energy and their support for renewable energies. Christian charity organizations and conservative political parties both stand for traditional family values and against family planning. But does this mean they should work together? Often political parties sponsor NGOs, but is this sponsoring even acceptable? There are several arguments which we would like to consider. The credibility of NGOs as independent organizations and their ability to pursue their social interests are harmed by political sponsoring. The credibility of NGOs decreases, because more often than not, the interests of political parties are more important than the original agenda of the NGOs, due to (financial) sponsoring. The reason for political parties to engage with NGOs in the form of political sponsoring is to increase attention for the statements on the political agenda. NGOs often have more resources and are less restrained to all sorts of rules and laws to protest in rigorous actions. However, this money can only be invested when the NGO compromises its own agenda with the agenda of the political party, which means that they might have to compromise on their own values, missions and visions. Hence the question rises; how can an NGO be called non-governmental when there is a political influence? A counterargument for this is that there is a difference between a political party and the government. Of course this is the case, but a political party is a part of the government. In the Netherlands it is even the case that the political parties get subsidy by the government, so these are inseparable. Thus we argue you can? t call a NGO non-governmental anymore when it is sponsored by political parties, which significantly decreases their credibility. Democratic control of political action that is ‘outsourced’ to NGOs and is therefore beyond democratic control. When a political party is chosen to participate in a country’s parliament, this is done in a democratic way. People can vote for the party that has arguments and goals closest to the person’s own vision. However, the board of an NGO is not chosen in a democratic way, they are simply hired because they are the ‘right person to do the job’. When NGOs will engage in political actions, people who are not democratically chosen will gain political power. The accountability of political parties to their stakeholders, in particular those who may not agree with the objectives of the NGOs that are sponsored, is harmed by political sponsoring. When people vote democratically for a political party, they vote for the agenda the political party has before engaging with any other organization. When political parties go and sponsor NGOs, the party most likely has to compromise on its own agenda to get to an agreement with an NGO. Citizens now are ‘voting’ for NGOs without knowing this. The voters do often not have a say in which NGOs are sponsored, so there is a great likelihood that part of the political party’s stakeholders will not approve of the chosen NGOs at all. The missions and visions of these organizations could be in contradiction with the opinions of the stakeholders and voters, and they have absolutely no control over this. Proponents of political sponsoring say that the voters don’t compromise, because they have the same goal as the political parties. We would like to stress here that even though someone has the same goal, you don’t have to agree with the actions that are taken. Especially actions of NGOs, which are most commonly known as radical, can get a lot of resistance by the voters and other stakeholders of the political parties. An important question you can ask yourself in the light of this last argument is: Does the end justify the means? Does the common goal lead to an acceptance of all (radical) actions taken by NGOs? This is an important question, especially for the stakeholders of the political party, because by political sponsoring all the stakeholders of the parties (including the voters) indirectly approve of the NGOs’ actions.

Development of New Medicines A History

Development of New Medicines A History AnnaMaria Roca As many diseases were able to be cured due to new medicines, new diseases are soaring such as AIDS. However, peoples lives have expanded all around the world due to so many studies that even included drugs. As strange as it sounds, medical drugs became the new thing to cure certain diseases such as tuberculosis. During the time of the 20th century, the medical advances increased in many areas. The advancement evolved in many areas in biology, chemistry, physiology, pharmacology, and technology. Due to the knowledge that brought to their understanding, diseases got new treatments and cures as more studies grew larger. â€Å"Toward the end of the 19th century the study of herbal, chemical, and mineral remedies (what was called material medica) was transformed into the laboratory science of pharmacology(Planetseed)†. Plant drugs such as opium were being analyized and examined. After a while, it was ready to be manufactured due to researchers becoming comfortable of their knowledge about the drugs. The pharmaceutical industry was marketing these products near the start of the 20th century. This is when aspirin was invented as the company Bayer used a systematic chemical named acetylsalicylic acid. Paul Ehrlich studied in pharmacology and created the first effective treatment for syphilis. He manufactured the arsenic-based compound Salvarsan in 1909. Ehrlich also created the word â€Å"chemotherapy† and due to that, formed the first antibiotic drug. Later on, a guy named Gerhard produced the first useful sulfa drug which is also an antibiotic. This was used to treat streptoccal, strep, and diseases, including meningitis. Even though viral diseases weren’t being cured by antibiotics, antiviral vaccines did. Smallpox and polio were important to the vaccines that cured them. Polio, which is mainly a disease of childhood, causes paralysis. Jonas Salk and Albert Sabin were two scientist that worke to develop a polio vaccine. However, two different versions of this vaccine were developled, which were brought into the world in the mid-1950s. Salk’s developed the vaccine that was used on the deadly virus, while Sabin’s was used on the live one. Both that were used resulted in success. Polio was mostly put to rest by the end of the 20th century. In the 1920s, Alexander Fleming studied mold samples and found something that could be very important in the medical field. Mold was growing on bacteria samples which killed them. He recognized the mold as penicillin. During World War II, they used this with their extended research on injured soldiers to test it out the new drug. It proved very effective against anthrax, tetanus, and syphilis. This was also the first drug that worked against pneumonia. â€Å"Antiretroviral drugs were developed in the 1980s to combat AIDS. (Retroviruses are a class of virus.) Viruses mutate so quickly, however, that developing antiviral (and antiretroviral) agents has proved very difficult (Planetseed)†. So due to this, the multiple studies and hard work to develop a vaccine for malaria and AIDS are unsuccessful. Other antiviral vaccines were also developed to cure measles, chickenpox, and influenza. Vaccines against human papillomavirus and shingles became available in 2006. The first antiviral drug in the 1970’s were acyclovir that helped against some forms of herpes. However, this doesn’t cure herpes but its useful for not breaking out in herpe sores or blisters. Researchers have used many different approaches to develop drugs for patients. One major revolution in treating illnesses was a new understanding of theimmune system. The advancement in immunology has brought progress to all of the autoimmune diseases. The autoimmune diseases include type 1 diabetes, lupus, muscular dystrophy, and rheumatoid arthritis.the research has led to the development of immunotherapy. That would the use of drugs to modify the immune system. As immunosuppressive drugs help treat autoimmune diseases, it also is a great success in the area of organ transplantation. First transplant to occur where the kidneys and then soon later become the first heart transplants. However, those patients didn’t survive that long due to their body’s immune system rejecting the new organs. Cyclosporins was then created as the first effective immunosuppressive drug to fix that problem. This advanced even further for todays modern surgery that allows any organ of the human body to be transplanted from one individual to another. AIDS brought the science of immunology to new studies. AIDS was considered a death sentence since it destroy s the immune system as it resists infection. However, antiretroviral drug treatments extends the lives of individuals for years who are infected for many years, but it still doesn’t have a real cure. Studies in the immunological medical search also dealt with genetics. The body’s cells and organisms that could infect it were studied. They then understood the roles of genes, the chromosomes and cell metabolism. Deocyribonuclei acid, also known as DNA is located at the core of the chromosome. After the study of the body’s cells, the biggest breakthrough then happened. A biochemist Frank Crick, and biologist James Watson were able to interpret the structure of DNA and were then able to use it in medicine. They found out that many diseases can be drawn to genes or defective chromosomes. Due to these findings, it is now possible to be tested for diseases like cystic fibrosis, huntingtyons chorea and forms of breast cancer. Genetic engineering even allows us to generate new drugs such as insulin, interferon, human growth hormone, and other hormones used to stimulate blood cell production. Physicist Wilhelm Conrad Roentgen discovered X-rays and made it capable to look at the internal organs of the body. This resulted in easier diagnoses for broken bones, cancer, and other diseases. Later on a physiologist, invented the first electrocardiograph. This was used for people with heart problems which the device was used to record electrical activity of the heart muscles. Tubes were then used to drain fluids or used to put in medicine were put into the heart and liver. The technologies that were discovered were ultrasound imaging, computerized tomography scans, positron emission tomography scans and magnetic resonance imaging. X-rays are a form of radiation which you would consider very dangerous to the body. After a while Radiologists realized that x rays were a form of radiation and are very dangerous to the body which resulted in them now using the lowest doses possible. They also became more knowledgeable about the use of X-rays to destroy unwanted cells. Radiation has become a treatment for cancer. Technology also helps people who need surgery. It allows the surgeon to look into further of the body which also allows radical invasive surgeries. Flexible endoscopes also became useful for hernias, gall bladders, kidneys, and knees. It is based on a fiber optic technology which is used for a keyhole surgery. It is a scope that has a laser which can cut like a sharp knife which makes a tiny incision. During the mid 20th century, a heart-lung machine was manufactured. It keeps patients alive by maintaining blood circulation while a surgeon is operating on an unbeating heart. Artificial organs are also a development that became useful for many individuals. Due to the fact that there aren’t enough organs for people, artificial organs help them to survive until one is found for them. Hemodialysis which was developed by a scientist named Willem Kolff. It helps patients live longer with kidney failure. Missing limbs were also being helped due to the development of prosthetics. Artificial limbs use to be made of metal and wood which later on turned into plastic that was developed in the mid-20th century. â€Å"But now, advanced materials, such as carbon fiber, high-tech plastics and metals, have enabled researchers to create devices that operate by electronic attachment to the muscles(Planetseed)†. In otherwords, Individuals lives have expanded all around the world due to so many studies of different things. The medical advancement evolved in many areas in biology, chemistry, physiology, pharmacology, and technology. Due to the knowledge that brought to their understanding like the medical drugs becoming a factor of helping people.
