Medicine in Ancient Egypt vs Ancient Greece Essay - 753 Words

Ancient civilizations played a massive role in how physicians today practice medicine. Without the ideas of ancient Egypt and ancient Greece, modern medicine may have been different. I feel that these two civilizations are responsible for many diagnostic tools we use today. I will be comparing and contrasting the medicinal practices of ancient Egypt and ancient Greece. By reading various papyri we are able to dive into the Egyptian practice of medicine. These papyri explore various illnesses and their cures. Papyrus texts reveal that doctors had detailed knowledge of the various body systems. The knowledge of medicine, anatomy and the functioning of the human body has been attributed to the embalming procedures practiced by the†¦show more content†¦Like that of Egypt, ancient Greece also believed in gods. Asclepius is the god of medicine and healing. Healing temples were built in Asclepius’ honor. People would flock to these healing temples because they believed that all of their illnesses would be cured. Greek physicians also believed in using magic and rituals and cure patients of sickness. In Greece, medicine and religion were strongly tied together. Hippocrates, known as â€Å"the father of medicine† wanted to separate medicine from the divine. He began to question patients to properly help them. Hippocrates would ask patients how they felt, he would check their symptoms and then diagnosis and treat them. He influenced our world of modern medicine because this is how physicians today treat patients. He also introduced case studies, which was the first step in modern medicine. Greeks also used various herbs to treat illness. Anise, a flowering plant, was used to help relieve women of menstrual cramps. Black hellebore was used to help treat paralysis and gout. Greeks also believed that we were made out of substances known as the four humors; sanguine (blood), choleric (yellow bile) , melancholic (black bile) and phlegmatic (phlegm). Gr eeks believed that if you were healthy, that was because your four humors were balanced. If you had too much of one humor, you would be unbalanced and you would feel ill.

A Mision Statement Free Essays

Mission Statement 2 The Importance of a Mission Statement In helping students achieve at their greatest potential it is necessary for me to provide them with the necessary tools for accomplishing high success. One vital tool for my success (Canter, 2009) as well as the success of my students is to have a mission statement about my teaching beliefs that help guide my instructional planning, interactions with students and difficult times that might arise during teaching. Another tool that will help drive my mission statement is to collaborate with colleagues, parents and various organizations in order to stay abreast as to what changes need to take place in and out of the classroom. We will write a custom essay sample on A Mision Statement or any similar topic only for you Order Now In staying deeply committed to my mission statement, it will be important for me to display it in my classroom as a constant reminder of what I want to accomplish as a teacher. My mission is as follows: To create a safe and positive learning environment that will allow students to achieve at their greatest potential with an emphasis on recognizing individual differences. After intensely collaborating with several colleagues and a parent, I found it necessary to revise my mission statement in order to clarify what is most important to me as a teacher. My revised statement: To create a safe and positive learning environment while developing high morals and values, with an emphasis on academic excellence by recognizing individual differences in a multicultural society. As a daily reminder of what I would like to accomplish as a teacher, I would display my mission statement on the front wall of my classroom as well as tape it on the inside of my lesson plan book. By displaying my mission statement on the front wall, it will not only keep me reminded as to what I want to accomplish, but it will also give my students, their parents, and my colleagues the opportunity of knowing what my goals are as an educator. By having my mission Mission Statement 3 The Importance of a Mission Statement statement taped in my planning book as a constant reminder of my mission statement, it will also help guide me during my instructional planning. Every classroom that I have had, consisted of students on various academic levels. Therefore, in my instructional planning; I will create assignments and strategies so that each student can successfully learn at his or her academic level. It is my desire to have comfortable and positive interactions with all students and treat each with dignity and respect. I have experienced that when students feel safe and are comfortable in the classroom with their teacher, they are more at ease with learning or even making mistakes. Also, in order to make a positive difference in the lives of my students, my interactions with them must remain respectful at all times. Once I loose their respect, it will be difficult to gain it back. At the same time, it is also important for students to show respect with their teacher and other people as well. Reflecting on a book, (Nieto, 2003) there are many challenges and obstacles that teachers face in their career. Even though I am viewed as a positive person, there are times when difficulties arise. My most difficult times are meeting deadlines, unpleasant conferences with parents or colleagues and behavioral challenges with a student. During times of difficulty and doubt is when I will need to read and reread my mission statement the most, as a reminder of what I want to accomplish as a teacher. However, what ever the difficulty is, by staying focused on my mission statement will help in achieving my goals. Therefore, while staying focused, it is also imperative that I remain positive. Mission Statement 4 The Importance of a Mission Statement In conclusion, with the guidance of my mission statement, I hope to build a strong foundation for academic excellence in the classroom. In having a strong foundation for academic excellence, it is important for all students to demonstrate respect, good morals and values that will help them develop as a learner and a person. As an effective teacher, I should exemplify characteristics that will gain the trust and belief from my students (Kottler, A. , Zehm, Kottler, E. , 2005). Also, staying focused and committed on a daily basis are essential actors I need to exhibit in order to successfully achieve my goals. In short, constantly reminding myself, as to what I want to accomplish for maintaining a highly-qualified teacher is vital for my success. References Kottler, J. A. , Zehm, S. J. , Kottler, E.

Positive Genetic Engineering Essay Example For Students

Positive Genetic Engineering Essay Genetic Engineering: A leap in to the future or a leap towards destruction?IntroductionScience is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from an analytical engine, to a calculator, to a computer. However, science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history has science be able to so deeply affect our lives as genetic engineering will undoubtedly do. With the birth of this new technology, scientific extremists and anti-technologists have risen in arms to block its budding future. Spreading fear by misinterpretation of facts, they promote their hidden agendas in the halls of the United States congress. They fear that it is unsafe; however, genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offspring. Genetics achieved its first foothold on the secrets of natures evolutionary process when an Austrian monk named Gregor Mendel developed the first laws of heredity. Using these laws, scientists studied the characteristics of organisms for most of the next one hundred years following Mendels discovery. These early studies concluded that each organism has two sets of character determinants, or genes (Stableford 16). For instance, in regards to eye color, a child could receive one set of genes from his or her father that were encoded one blue, and the other brown. The same child could also receive two brown genes from his or her mother. The conclusion for this inheritance would be the chil d has a three in four chance of having brown eyes, and a one in three chance of having blue eyes (Stableford 16). Genes are transmitted through chromosomes which reside in the nucleus of every living organisms cells. Each chromosome is made up of fine strands of deoxyribonucleic acids, or DNA. The information carried on the DNA determines the cells function within the organism. Sex cells are the only cells that contain a complete DNA map of the organism, therefore, the structure of a DNA molecule or combination of DNA molecules determines the shape, form, and function of the offspring (Lewin 1). DNA discovery is attributed to the research of three scientists, Francis Crick, Maurice Wilkins, and James Dewey Watson in 1951. They were all later accredited with the Nobel Prize in physiology and medicine in 1962 (Lewin 1). The new science of genetic engineering aims to take a dramatic short cut in the slow process of evolution (Stableford 25). In essence, scientists aim to remove one gene from an organisms DNA, and place it into the DNA of another organism. This would create a new DNA strand, full of new encoded instructions; a strand that would have taken Mother Nature millions of years of natural selection to develop. Isolating and removing a desired gene from a DNA strand involves many different tools. DNA can be broken up by exposing it to ultra-highfrequency sound waves, but this is an extremely inaccurate way of isolating a desirable DNA section (Stableford 26). A more accurate way of DNA splicing is the use of restriction enzymes, which are produced by various species of bacteria (Clarke 1). The restriction enzymes cut the DNA strand at a particular location called a nucleotide base, which makes up a DNA molecule. Now that the desired portion of the DNA is cut out, it can be joined to anothe str and of DNA by using enzymes called ligases. The final important step in the creation of a new DNA strand is giving it the ability to self-replicate. This can be accomplished by using special pieces of DNA, called vectors, that permit the generation of multiple copies of a total DNA strand and fusing it to the newly created DNA structure. Another newly developed method, called polymerase chain reaction, allows for faster replication of DNA strands and does not require the use of vectors (Clarke 1). Viewpoint 1The possibilities of genetic engineering are endless. Once the power to control the instructions, given to a single cell, are mastered anything can be accomplished. For example, insulin can be created and grown in large quantities by using an inexpensive gene manipulation method of growing a certain bacteria. This supply of insulin is also not dependant on the supply of pancreatic tissue from animals. Recombinant factor VIII, the blood clotting agent missing in people suffering from hemophilia, can also be created by genetic engineering. Virtually all people who were treated with factor VIII before 1985 acquired HIV, and later AIDS. Being completely pure, the bioengineered version of factor VIII eliminates any possibility of viral infection. Other uses of genetic engineering include creating disease resistant crops, formulating milk from cows already containing pharmaceutical compounds, generating vaccines, and altering livestock traits (Clarke 1). In the not so distant future, genetic engineering will become a principal player in fighting genetic, bacterial, and viral disease, along with controlling aging, and providing replaceable parts for humans. Medicine has seen many new innovations in its history. The discovery of anesthetics permitted the birth of modern surgery, while the production of antibiotics in the 1920s minimized the threat from diseases such as pneumonia, tuberculosis and cholera. The creation of serums which build up the bodies immune sys tem to specific infections, before being laid low with them, has also enhanced modern medicine greatly (Stableford 59). All of these discoveries will fall under the broad shadow of genetic engineering when it reaches its apex in the medical community. Canada's Copyright Law EssayThe evolution of man can be broken up into three basic stages. The first, lasting millions of years, slowly shaped human nature from Homo erectus to Home sapiens. Natural selection provided the means for countless random mutations resulting in the appearance of such human characteristics as hands and feet. The second stage, after the full development of the human body and mind, saw humans moving from wild foragers to an agriculture based society. Natural selection received a helping hand as man took advantage of random mutations in nature and bred more productive species of plants and animals. The most bountiful wheats were collected and re-planted, and the fastest horses were bred with equally faster horses. Even in our recent history the strongest black male slaves were mated with the hardest working female slaves. The third stage, still developing today, will not require the chance acquisition of super-mutations in nature. Man will be able to create s uch super-species without the strict limitations imposed by natural selection. By examining the natural slope of this evolution, the third stage is a natural and inevitable plateau that man will achieve (Stableford 8). This omniscient control of our world may seem completely foreign, but the thought of the Egyptians erecting vast pyramids would have seem strange to Homo erectus as well. ConclusionMany claim genetic engineering will cause unseen disasters spiraling our world into chaotic darkness. However, few realize that many safety nets regarding bioengineering are already in effect. The Recombinant DNA Advisory Committee (RAC) was formed under the National Institute of Health to provide guidelines for research on engineered bacteria for industrial use. The RAC has also set very restrictive guidelines requiring Federal approval if research involves pathogenicity (the rare ability of a microbe to cause disease) (Davis, Roche 69). It is well established that most natural bacteria do not cause disease. After many years of experimentation, microbiologists have demonstrated that they can engineer bacteria that are idence of regeneration is all around and the science of genetic engineering is slowly mastering its techniques. Regeneration in mammals is essentially a kind of controlled cancer, called a blastema. The cancer is deliberately formed at the regeneration site and then converted into a structure just as safe as their natural counterparts (Davis and Rouche 70). In fact the RAC reports that there has not been a single case of illness or harm caused by recombinant bacteria, and they now are used safely in high school experiments (Davis and Rouche 69). Scientists have also devised other methods of preventing bacteria from escaping their labs, such as modifying the bacteria so that it will die if it is removed from the laboratory environment. This creates a shield of complete safety for the outside world. It i s also thought that if such bacteria were to escape it would act like smallpox or anthrax and ravage the land. However, laboratory-created organisms are not as competitive as pathogens. Davis and Roche sum it up in extremely laymens terms, no matter how much Frostban you dump on a field, its not going to spread (70). In fact Frostbran, developed by Steven Lindow at the University of California, Berkeley, was sprayed on a test field in 1987 and was proven by a RAC committee to be completely harmless (Thompson 104). Fear of the unknown has slowed the progress of many scientific discoveries in the past. The thought of man flying or stepping on the moon did not come easy to the average citizens of the world. But the fact remains, they were accepted and are now an everyday occurrence in our lives. Genetic engineering is in its period of fear and misunderstandifng, but like every great discovery in history, it will enjoy its time of realization and come into full use in society. The world is on the brink of the most exciting step into human evolution ever, and through knowledge and exploration, should welcome it and its possibilities with open arms.

Shaving by Leslie Norris free essay sample

The short story â€Å"Shaving† is a coming-of-age piece that stresses the need for a family to have a strong and responsible leader. In the short story Barry, the main character, is in a position where his father is dying and he has the responsibility of taking care of him. One day after school Barry comes home to shave his father because he is too sick to do it himself. Through this the reader is able to comprehend the idea that Barry is ready to take over his fathers spot in the family. Leslie Norris illustrates that Barry is ready to become patriarch of the family through direct characterization, contrast with weather and symbolism. In â€Å"Shaving† Leslie Norris portrays that Barry is ready to become the leader of the family through direct characterization. Barry is mature and strong, yet his father is weak and now has to rely on Barry for everything. We will write a custom essay sample on Shaving by Leslie Norris or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Norris begins implementing this message by describing Barry as how â€Å"He walked solidly now and often alone. He was tall, strongly made; his hands and feet were adult and heavy. The room in which all his life he’d grown had become to small for him† (Norris 1). This promotes the idea that Barry is not just mentally but physically ready to become patriarch of the family. He has grown up and is able to function without depending on someone such as his father. As the story progresses the reader then gets characteristics of â€Å"His father’s face was fine-skin and pallid carried a dark stubble of beard† (Norris 2) that needed to be shaved. The reader can infer that Barry’s father is weak and he is ready to let Barry take over his position in the family. This is justified when Barry’s father lets him shave his face. His father is letting go of himself and is relying on Barry to pick up where he is leaving off. Leslie Norris uses contrast with weather to portray that Barry is ready to become the head of the family. Norris begins indicating this message when the end of the story approaches with â€Å"An overnight frost had still been thick on the roads, but the brisk April sun had soon dispersed it and now he could feel the spring warmth on his back through the thick tweed of his coat† (Norris 1). This demonstrates a change in season but also has the more  profound meaning of a change from boy to man. Manhood is approaching quickly and is hanging over Barry, as it will soon engulf him once his father passes away. As the story reaches its conclusion Barry’s by the window in his parents bathroom when â€Å"The window was full in the beam of dying sunlight and Barry stood there illuminated in its golden warmth for a whole minute, knowing it would soon be gone† (Norris 1). The idea of golden warmth helps emphasize that his dad is present and Barry’s standing looking out knowing that the end will soon come for his father’s life. This exhibits that Barry is mentally mature enough for his dad to soon pass away. Leslie Norris uses symbolism often throughout the short story â€Å"Shaving†, to represent that Barry is ready to become the patriarch of the family. She uses symbolism to bring out important ideas and points throughout the text. When Barry is in his parent’s bathroom preparing a tray of tools to help him shave his father, there is a cup sitting there that he notices. Since â€Å"The cup was much older than Barry. A pattern of fine translucent cracks fine as a web had work itself haphazardly, invisible almost through the white glaze† (Norris 2). This cup represents Barry’s father and how old and decrepit he is becoming. The cracks symbolize the weakness and defeat that his father is feeling and experiencing as he deteriorates himself. As Barry continues to assemble the tray â€Å"His father’s razor was in a blue leather case, hinged at the broad edge was one hinge broken† (Norris 2). The blue leather case symbolizes Barry’s father being sick. The broken hinge also represents the same meaning. This supports the idea that Barry’s father is breaking down and dwindling. He continues to get worse as time goes on and needs Barry to help put back together the pieces. Through direct characterization, contrast with weather and symbolism Leslie Norris illustrates that Barry is ready to become the patriarch of the family. Barry isn’t just mentally but physically ready to take over his father’s position. His father is weak and is ready to let Barry occupy his spot in the family. Norris portrays this through direct characterization of Barry and his father. The use of contrasting with weather also amplifies the idea that his father is willing to relinquish his position in the family to Barry. He is mentally able to conquer the tasks that his father’s position entails. Finally Norris uses symbolism to express the idea that Barry’s father is deteriorating and Barry’s job is to pick up where his father is leaving off. It’s a parent’s job to look after their child but in some cases it’s the child’s job to look after the parent.
