The Humoral Theory Of William Shakespeares Romeo And Juliet

The humoral theory is one of the oldest theories of Medicine that proposed that our bodies are made up of four different humours: black bile, blood, phlegm, and yellow bile. It was believed that while in good health the humours were in a harmonious balance throughout the body but illness is said to have disrupted that balance causing one or more humour to become disordered. It is also said that the mind is effected by the equilibrium of the four temperaments known as melancholic, sanguine, choleric, and phlegmatic and that they dispersed to make up certain characteristics or personality traits. Critics have long described Shakespeare as using these humours and temperaments as a way for the audience to understand the character, plot and other aspects of his plays. In such plays as Romeo and Juliet where critics have described Romeo as being a melancholy figure it is exceptionally brought about by using the four humours involved in the humoral theory that is said to have first originat ed by Hippocrates and later elaborated on by Galen. The four humours include Black Bile which is related to the melancholic temperament and said to be associated with the element earth, the season of winter, the planet Saturn, the spleen, and cold and dry qualities. The humour Blood is related to the sanguine temperament and associated with the element air, the season spring, the planet Jupiter, the heart, and hot and moist qualities. While Phlegm is associated with the temperament phlegmaticShow MoreRelatedWilliam Shakespeare s Romeo And Juliet1998 Words   |  8 PagesIn the plays, Romeo and Juliet and 1 Henry VI, by William Shakespeare, the concept of humoral theory helps to explain many of the behaviors the characters display in the plays. Humoral theory works to explain workings within the human body. According to the Welcome Library of London, â€Å"Humors existed as liquids within the body and were identified as blood, phlegm, black bile and yellow bile. These were in turn associated with the fundamental elements of air, water, earth and fire.† The elements are

Pablo Picasso - Biography and Artwork - About.com

Pablo Picasso, also known as Pablo Ruiz y Picasso, was singular in the art world. Not only did he manage to become universally famous in his own lifetime, he was the first artist to successfully use mass media to further his name (and business empire). He also inspired or, in the notable case of Cubism, invented, nearly every art movement in the twentieth century. Movement, Style, School or Period: Several, but best known for (co-)inventing Cubism Date and Place of Birth October 25, 1881, Mà ¡laga, Spain Early Life Picassos father, fortuitously, was an art teacher who quickly realized he had a boy genius on his hands and (almost as quickly) taught his son everything he knew. At the tender age of 14, Picasso passed the entrance exam to the Barcelona School of Fine Arts - in just one day. By the early 1900s, Picasso had moved to Paris, the capital of the arts. There he found friends in Henri Matisse, Joan Mirà ³ and George Braque, and a burgeoning reputation as a painter of note. Body of Work Before, and shortly after, moving to Paris, Picassos painting was in its Blue Period (1900-1904), which eventually gave way to his Rose Period (1905-1906). It wasnt until 1907, though, that Picasso really raised a commotion in the art world. His painting Les Demoiselles dAvignon marked the beginning of Cubism. Having caused such a stir, Picasso spent the next 15 years seeing what, exactly, could be done with Cubism (such as putting paper and bits of string in a painting, thus inventing the collage). The Three Musicians (1921), pretty much summed up Cubism for Picasso. For the rest of his days, no one style could maintain a hold on Picasso. In fact, he was known to use two or more different styles, side by side, within a single painting. One notable exception is his surrealistic painting Guernica (1937), arguably one of the greatest pieces of social protest ever created. Picasso lived long and, indeed, prospered. He grew fabulously wealthy from his phenomenal output (including erotically themed ceramics), took up with younger and younger women, entertained the world with his outspoken remarks, and painted almost right up until he died at the age of 91.

OMAM Loneliness and Companionship - 829 Words

OMAM Loneliness and Companionship Of Mice and Men is a skillful novel, that portrays the idea of loneliness throughout the novel. Two men, George and Lennie are there for each other through everything. They also have their tiffs just like any other friends. There are several clearly stated themes running through the novel. But, the two themes that interact with each other are loneliness and companionship. Many of the characters do suffer from loneliness in the novel Of Mice and Men. George lets everybody know early on in the novel that he is lonely. When George reminds Lennie that Guys like us, that work on ranches, are the loneliest guys in the world† (Steinbeck Section 1). Men like George who travel from farm to farm usually never have anyone to look to for companionship and protection. As the story goes on, Candy, Crooks, and Curley’s wife all state their deep loneliness. Crooks says, â€Å"A guy goes nuts if he aint got nobody. Dont make no difference who the guy is, longs hes with you. I tell ya, I tell ya a guy gets too lonely an he gets sick (80). In a world with no friends to confide in, random people will have to do. Each of the characters search for a friend, someone to confide in and be able to talk to on an everyday basis, as Crooks says. In the end, however, companionship of Curley’s kind seems impossible to find. For George, when Lennie dies, Georg e’s dreams and hopes of finding a companion disappears.

Global Warming and Climate Change Essay - 2336 Words

Global warming and the greenhouse effect are issues discussed by scientists all the time. A natural process that keeps earths temperature at a livable rate is called the greenhouse effect. The energy from the sun warms up the earth when the rays from the sun are absorbed by greenhouse gasses. The gasses then become trapped in the atmosphere. Carbon dioxide, water vapor, methane and nitrous oxide are the most common greenhouse gasses. Greenhouse gases cause the radiant heat of the sun to be trapped in the Earths lower atmosphere which causes global warming. If there weren’t any greenhouse gasses, the earth would be really cold due to very little sun rays being absorbed on the earth. Global warming can and†¦show more content†¦Every time the temperature keeps rising, the more carbon dioxide will be released. When this process gets going, it is very hard to keep in control.

Tang Dynasty free essay sample

The Tang dynasty is one of China’s most remarkable and glistening historic periods known today. The Tang dynasty established a strong centralized state system, starting in 618 after the fall of the Sui dynasty in the early seventeenth century. Although the early Tang monarchs were good rulers over all, one emperor in particular parts from the group. â€Å"Li Shih-min† who would assume the title of T’ai-tsung. T’ai-tsung was the son of the first emperor in the Tang dynasty Gaozu. He was a bold, energetic, and powerful emperor that was determined to solve the international problems that had destroyed past weaker dynasties. T’ai-tsung was responsible for the recreation of Chinese government. (â€Å"quote source†) According to â€Å"source 1† at the top of the hierarchy was the emperor; below him were three administrations; council of the state, military affairs, and the censorate. The most important out of the three was the council of the state, which drafted policy, reviewed policy, and implemented policy. The military affairs directed the military under the control of the emperor. The censorate watched over the government and the government officials to prevent misgoverning and corruption. The new government policies set into place that T’ai-tsung had ingeniously derived led to the central state system working. The geographical area of the Tang Empire stretched across a vast part of China. Chang’an was the western capitol of the Tang dynasty, and became a centralized meeting place for traders, merchants, artist, and religious leaders. Chang’an became one of the richest and most powerful cities in the world at that time. The Tang dynasty flourished in part due to the new economic and trading ties with different regions. Trade was possible because the government maintained good foreign trade relation. The Tang Empire traded with India, Middle East, and Central Asia. Silk road connected Chang’an to Greece, Rome, and parts of Europe. This highway brought new products of trade to the countries which included silk, tea, herbs, spices and hand crafted items. The Tang dynasty is responsible for many great things, the dynasty had several world changing inventions, famous literature, and changing religious movements that would spark a revolution that would forever change the way Chinese people interacted and lived within society. One reason that the Tang Dynasty is known for being one of the best empires in Chinese history is because of the brilliant and world changing inventions that some of the greater minds in that era created, forever changing the way people lived. Inventions are essential for ever changing technologic advances towards a greater way of life and the Chinese understood this concept with the invention of making paper, gunpowder, printing technique and compass. All of which were not completely new concepts but the Tang Dynasty found ways to improve some of the already thought of inventions. The invention of paper making greatly contributed to the spread and development of civilization. Prior to the invention of paper making; bones, tortoise shells, and bamboo slips were all used as writing surfaces. As Chinese civilization developed the usage of their materials proved to be unsuitable, because they were extremely too heavy and took up a lot of space. The next material used in trying to make paper was the combination of hemp fiber and silk, but the quality of the material was found to be unsatisfactory. The use of that material also had far better uses . According to (â€Å"quote† ) Xue fu wu che which is a Chinese idiom describing a learned man. The story behind paper making is that a scholar by the name of Hui Shi who lived during the Tang dynasty. He needed five charts to carry around his books while teaching. At the time books were made of wood and bamboo slips, so one could imagine how heavy and inconvenient they would be to carry from place to place. Not to mention how much space the books would take up. If a person had ten or more books that person might need a cart with wheels just to carry them around. Reading books at the time, a person would not only need to have brain power, but would also have to be in good physical condition. According to Chinese history experts â€Å"In 105 A. D. Cai Lun, a eunuch during the Tang dynasty, invented paper from worn fishnet, bark, and cloth. † The fact that these raw materials were available at such a low cost and easily able to obtain the process of making paper in large quantities just made sense! The technique of paper making was eventually exported to Korea in 384 A. D. Japan acquired the skill of making paper when a Korean monk traveled there taking the information and process with him. Paper making traveled to the Arab empire during a war between the Arabs and the Tang dynasty, when some of the soldiers of the Tang army, and paper making workers were captured during the war. Soon after, a paper factory was established in the Arab nation. In the eleventh century the skill of making paper was carried to India when Chinese monks traveled there in search for spiritual enlightenment. The skill then traveled the world from one continent to the next, eventually the skill was brought to America. The invention of paper is accredited to one of the greatest dynasties know in Chinese history, the Tang Dynasty. The Tang dynasty was also responsible for the invention of gunpowder. In Chinese, the word gunpowder is called, huo yao, which means flaming medicine. Unlike so many of the other Chinese inventions the making of gunpowder was pure accidental. Gunpowder is an invention that has had a profound effect on human society. Gunpowder was first discovered when alchemist was trying to make an elixir of immortality. According to legend â€Å"During the Tang dynasty, around 850 A. D. , an enterprising alchemist (whose name has been lost to history) mixed 75 parts saltpeter with fifteen parts charcoal and ten parts sulfur. This mixture had no discernable life-lengthening properties, but it did explode to an open flame. According to a text from the era, â€Å"smoke and flames result, so that (the alchemist) hands and faces have been burnt, and even the whole house where they were working burned down. † After the discovery of gunpowder the Chinese people found many useful purposes for this new and amazing invention. It is thought that the only use for gunpowder was for making fireworks, used by the Chinese during celebrations, such as, parades and ceremonial events for the emperor; but gunpowder was destined for greater usages. One usage of gunpowder was in weapons.

The question is this: How can we distinguish between the environmental causes of behavior (the influence of parents, siblings, family, friends, schooling, nutrition, and all the other experiences to which a child is exposed) and hereditary causes (those based on the genetic makeup of an individual that influence growth and development throughout life)?This question embodies the nature–nurture issue. In this context, nature refers to hereditary factors, and nurture to environmental influences.

Despite their differences over theory, developmental psychologists concur on some points. They agree that genetic factors not only provide the potential for specific behaviors or traits to emerge, but also place limitations on the emergence of such behavior or traits.For instance, heredity defines people’s general level of intelligence, setting an upper limit that—regardless of the quality of the environment—people cannot exceed. Heredity also places limits on physical abilities; humans simply cannot run at a speed of 60 miles an hour, nor will they grow as tall as 10 feet, no matter what the quality of their environment (Dodge, 2004; Pinker, 2004). Figure 1 lists some of the characteristics most affected by heredity.

Sepsis and Septic Shock Essay Example

Sepsis and Septic Shock Essay Sepsis refers to the uncontrolled systemic immune response to infection. It describes the condition known as systemic inflammatory response syndrome in which as infectious etiology is identified or suspected (Munford, 2001). The key element in sepsis is the overwhelming systemic inflammation as a result of the host’s reaction to microbial invasion. It involves augmented inflammatory signals in response to an infectious insult that is not controlled by local inflammatory processes. Bacteremia, which is the presence of bacteria and in blood or septicemia, which is the presence of any microbial agent in the blood can lead to sepsis. When the regulatory controls that put the inflammatory response in check are unable to contain the overwhelming reaction, unaffected organs are involved and severe sepsis ensues which is characterized by multiorgan dysfunction. As the homeostatic counterregulatory mechanism fails, sepsis progresses to septic shock, which is the presence of hypotension along with along with organ dysfunction. The hypotension, which is defined as systolic blood pressure of less than 90 mmHg or 40 mmHg less than the patient’s usual blood pressure, is unresponsive to fluid resuscitation. Unlike sepsis which is reversible, patients in septic shock have unfavorable prognosis and usually succumb despite aggressive treatment (Munford, 2001).EpidemiologyOver 10 million cases of sepsis have been reported in the United States based on a 22-year period study of discharge data from 750 million hospitalizations (Martin, Mannino, Eaton, Moss, 2003). Annually, approximately 750,000 people develop sepsis and more than 210,000 cases are fatal (Bernard, Vincent, Laterre, Larosa, Dhainaut, Lopez-Rodriguez et al 2001; Hotchkiss Karl, 2003). Despite advances in critical care management, sepsis has a mortality rate of 30 to 50 percent and is among the primary causes of death in intensive care units (Bernard et 2003; Mitchell, Cotran, 1999). It is believed th at the increasing incidence of severe sepsis is due to the growing population among the elderly as a result of increasing longevity among people with chronic diseases and the high prevalence of sepsis developing among patients with acquired immune deficiency syndrome (Munford, p.798 2001).PathophysiologyThere are a lot of factors attributable to the development of sepsis. Several studies have conflicting results on the pathologic basis of the disease and the exact mechanism involved has not been elucidated. The pathogenesis of sepsis is a series of complex interactions between offending microorganism and the host inflammatory, immune and coagulation responses. The accepted theory is that sepsis results from an uncontrolled inflammatory response in which our own defense system becomes so powerful that it causes more damage to our organs than the etiologic agent of the initial infection Hotchkiss Karl, 2003). This is based on the overstimulated immune response seen in studies of anim al models of sepsis which does not seem to correlate which the clinical picture in humans. Clinical trials involving anti-inflammatory agents have not been successful in patients with sepsis which led investigators to question if sepsis is indeed the result of uncontrolled inflammation (Hotchkiss Karl, 2003). In fact, sepsis with organ dysfunction is attributed to an inadequate immune response to primary local infection which allowed it to spill into the bloodstream and the ensuing tissue injury is primarily caused by superantigens and other virulence factors from the infecting microorganism (Russel, J.A., 2006).Approximately 70 percent of cases of septic shock are caused by gram-negative bacilli which produce endotoxin, hence the term endotoxic shock (Mitchell, Cotran, 1999). The endotoxins are the lipopolysaccharides(LPS) from the bacterial cell wall that are released after the wall is degraded during an inflammatory response. The reproduction of the hemodynamic picture of septi c shock through the injection of LPS alone shows that LPS is one of the main culprits of septic shock. The complex inflammatory cascade caused by LPS eventually leads to hypoxic injury and the multi organ failure is mostly evident in the brain, heart, kidneys, lungs, and gastrointestinal tract. The widespread hypoxia during septic shock causes the brain to develop ischemic encephalopathy while in the heart, cardiac muscles undergo coagulation necrosis and subendocardial hemorrhages. The kidneys undergo acute tubular necrosis as a result of extensive ischemic injury. This results into electrolyte disorders, oliguria and anuria which are severe complications of sepsis. Despite the high resistance of lungs tissues to hypoxic injury, diffuse alveolar damage can be seen in severe bacterial sepsis. In the gastrointestinal tract, hemorrhagic enteropathy develops which appears as patchy mucosal hemorrhages and necrosis. The liver undergoes fatty change and in severe ischemic injury, central hemorrhagic necrosis can be seen (Mitchell, Cotran, 1999).Clinical FeaturesThe clinical manifestations of sepsis are usually superimposed with the signs and symptoms of the primary infection and other underlying medical condition of the patient.However, in the course of the disease, an increasing intensity of inflammatory response to infection becomes evident although the rate varies among patients. Hyperventilation is usually one of the early signs. Manifestations of ischemic encephalopathy such as disorientation and confusion may also occur early in sepsis. They are usually seen among the elderly and in patients with preexisting neurocognitive deficits (Munford, 2001). Patients with hypotension usually presents with weak but rapid pulse accompanied by tachypnea and cold, clammy skin. However, patients in septic shock may be initially warm due to peripheral vasodilation in the skin (Mitchell, Cotran, 1999). It should be noted that some patients with sepsis are normothermic and e ven in the presence of infection, fever can be absent especially in neonates, elderly, and patients with uremia or suffering from alcoholism (Munford, p.801 2001).The occurrence of disseminated intravascular coagulation or DIC, which results from the widespread activation of the coagulation system, can predispose patients to ischemic necrosis especially to those with hypotension. This leads to skin lesions seen as pustules, cellulites, bullae or hemorrhagic lesions. Gastrointestinal involvement manifests as nausea, vomiting, diarrhea and ileus. Patients with stress ulcers may present with upper gastrointestinal bleeding. In cases of prolonged and severe hypotension, ischemic bowel necrosis may occur as well as acute hepatic injury. Elevation of serum levels of conjugated bilirubin often leads to cholestatic sepsis. Liver function test may reveal elevated blood levels of alkaline phosphatase which along with the elevated bilirubin represent an underlying hepatocellular or canalicular dysfunction (Munford, 2001).Treatment and PrognosisPatients with sepsis requires urgent management which is best accomplished in an intensive care setting by medical specialist experienced in the care of critically ill patients. The management entails immediate treatment of the focus of infection while providing adequate hemodynamic and ventilatory support.The appropriate antimicrobial therapy should be given immediately based on blood culture and sensitivity although an empiric initial treatment should be started based on known pathogens at identified sites of infection. An adequate antibiotic cover should include therapy against gram-positive and gram-negative microorganism. Pending results from blood cultures, empiric antimicrobial therapy can be based on several factors, especially in patients with no obvious source of infection. In immunocompetent adults, acceptable regimens include ceftriaxone or ticarcillin-clavulanate or piperacillin-tazobactam and imipenem-cilastin or mero penem. Gentamycin or tobramycin may be added to these regimens. If the causative agent is suspected to be methicillin-resistant staphylococcous areus, vancomycin should be added to these regimens (Munford, 2001). In patients with AIDS, ceftazidime, tircacillin-clavilanate or piperacillin-tazobactam plus tobramycin should be used. In patients with drug allergy to beta lactams, ciprofloxacin plus vancomycin and tobramycin should be used (Munford, 2001). Other factors to be considered are the presence of neutropenia or neutrophil count of less than 500 per microliter, splenectomy and history of intravenous drug abuse. These patients require appropriate antimicrobial cover based on their higher susceptibility to certain microorganisms.The immediate removal of the focus of infection is also important in the successful management of patients with sepsis. Sites of infection should be identified immediately and appropriate drainage should be done when possible. In patients with indwelling i ntravenous catheters, microbial cultures should be done and a new catheter should be placed in another site. Adequate hemodynamic and respiratory support should also be provided especially in patients with septic shock to prevent tissue injury secondary to ischemia. The pulmonary wedge pressure and central venous pressure should be monitored constantly. Metabolic support should also be provided. The urine output should be watched closely for oliguria and anuria. Diuretic therapy with furosemide may be used (Munford, 2001).Despite aggressive treatment, many patients with severe sepsis and septic shock succumb to the disease. Several new agents have been developed which should promising outcome in averting death. These are drugs that neutralize the bacterial endotoxin such as monoclonal antibodies to endotoxins and drugs that interfere with the mediators of inflammatory response such as monoclonal antibodies to tumor necrosis factor alpha. Another promising drug for severe sepsis is d rotrecogin alfa or recombinant human activated protein C which has shown antithrombotic, antiinflammatory, and profibrinolytic properties. A clinical study has shown that the drug significantly reduced the mortality in severe sepsis although due to its antithrombotic properties, the patients are at a higher risk of bleeding (Bernard, et al 2001).Further studies are necessary to better understand the pathogenesis leading to sepsis. The knowledge gained in these studies which further enhance the development of newer drugs with better safety profile. In addition, more clinical trials are important to assess the drug efficacy of existing drugs so that better management of sepsis can be formulated to improve the morbidity and mortality of the disease.
