Chronic Pancreatitis - Term Paper Example General Description Chronic Pancreatitis (CP) is a heterogeneous, progressive disorder of the pancreas characterized by a spectrum of symptoms pain, inflammation, diabetes mellitus, and pancreatic damage leading to significant loss of both endocrine and exocrine functions of the pancreas (Witt and associates, 2007; DiMagno & Dimagno, 2006). Pathology involves fibrosis in the pancreatic parenchyma that manifests irregularly. Other organs in the vicinity are also affected as consequence of the disease that may commence as an individual or a group of symptoms resulting from functional impairment of pancreas. The major clinical symptom of the disease is recurring or persistent pain within the abdomens. The chief cause of CP in the western world is alcohol abuse leading to alcoholic calcific pancreatitis (ACP). The other form of CP known as tropical calcific pancreatitis (TCP) prevalent in tropical countries is of uncertain etiology (Lee, 2011). Based on the risk factors CP is classified by the TIGAR-O (Toxic-metabolic, Idiopathic, Genetic, Autoimmune, Recurrent and severe acute, Obstructive) classification system (Nair tet al., 2007). Figure 1: Anatomy of the pancreas (http://www.britannica.com/bps/media-view/68636/1/0/0) Pancreas: Normal Physiology Pancreas is a retroperitoneal structure in the upper abdomen that can broadly be divided into head, body, and tail (figure 1). A major portion of pancreatic tissue comprises of acini (80%) that are responsible for the exocrine functions of the pancreas. Groups of aciniform spherical lobules that are interspersed with connective tissue. The central ducts of each lobule in which the secretions of the surrounding acinar cells accumulate, join to extralobular ducts that finally drain into the main pancreatic duct. The main pancreatic duct carrying the secreted digestive enzymes enters the hepatopancreatic ampulla along with bile duct. At the duodenal papilla, the enzymes enter the duodenum (Adda et al., 1984). The endocrine functions of the pancreas are performed by the richly vascularized islets of Langerhans. The islets of Langerhans comprise of beta, alpha and delta cells that secrete hormones insulin, glucagon, somatostatin respectively. The most abundant beta cells (73-75%) are centrally located and are surrounded by alpha cells (18-20%) and delta cells (4-6%). The rich vascularization allows for the transfer of hormones from the islets while the specific arrangement of the alpha, beta and delta cells allows paracrine regulation of hormones. Thus high concentrations of the insulin secreted by the central beta cells inhibit glucagon release from the peripheral alpha cells. The venous blood flow from the islets of Langerhans reaches the hepatic portal vein, rendering the liver the prime target for the impact of pancreatic hormones. The rich innervations of the pancreas ensure the release of several neurotransmitters in the pancreas that regulate the release and concentrations of hormones (Case, 200 6). During normal physiology, in the basal state, the secreted pancreatic fluid is mildly alkaline comprising a few proteins. Gastric distension and acid production during eating stimulate duodenal S cells causing the release of secretin. Under the influence of the secretin, a large quantity of the bicarbonate-rich watery liquid or the hydraulic secretion is released from the ductal cells of the smaller ducts.  

Positive Aspects of Technology Essay Example for Free

Positive Aspects of Technology Essay From man`s first invention of the wheel to modern day’s advanced computers, one can clearly see how far humans have developed with technology. Modern technology has provided mankind with numerous positive aspects; from getting to places in seconds to curing complex diseases. The most fundamental and important positive aspect of technology is that it gives humans the ability to share knowledge more effectively. Nowadays, a country is not defined by its wealth or influence, rather by its â€Å"ability to develop and advance knowledge† (Johnston 1). In the essay, The Diplomacy of Knowledge, author David Johnston states that, â€Å"information has never been so ubiquitous and so cheaply and easily shared† (1). In other words, information has never been so readily available, thanks to the fast growing Internet. The Internet allows billions of people to express their opinions and put forth their knowledge for others to see. Johnston also mentions that the foundations of the internet were laid by â€Å"300 years of discovery in math and science from Newton to Einstein† (2). Great scientists such as Newton to Einstein shared their experience and findings which have become the cause of all the ongoing technological development. For instance, the recent uprising in Libya was hugely successful due to the internet. Thousands of people posted Facebook statuses and communicated in numerous other ways. By sharing each other’s thoughts and knowledge, they were able to overcome the situation by establishing a strong and organized community. Moreover, new inventions are also greatly impacted by the sharing of knowledge and this can be evidently seen with a great discovery such as Insulin. Charles Best and Frederick Banting, a bio-chemist and a surgeon, are innovators from different fields. Both of them shared each other’s knowledge and brought forth one of the greatest discoveries of all time, insulin which saved millions of diabetic patients. In other words, today’s advancements in technology let the sharing of knowledge much more effectively, as it allows mankind to â€Å"[experience] unprecedented rates of change† (2). It also gives humanity the opportunity to undergo â€Å"rapid transformations, characterized by risk and opportunity on a global scale â€Å"(2). These changes brought through the sharing of knowledge bring an evolution in social and ethical factors within the society. In conclusion, technology has provided mankind with countless positive aspects, although the greatest aspect is the better collaboration of knowledge. From insulin to modern medicine, history has made it clear that great things can happen when everyone shares their learning with each other. As Thomas Jefferson mentions, â€Å"[by lighting] your candle with the flame of mine, my light is not diminished, it is enhanced† (2).

Creation Essay -- essays research papers

Creation The Creation Stories Did the creation of the earth and life begin by itself? Or did God create them? In the beginning, civilization started to question who created earth. There were many different views. In Genesis, Jinasena, and Buddha have their own thinking. There were some differences as well as similarities. In Genesis, it was stated that God created heaven and earth. Everything we saw is God's work. Even ourselves is come out from him. In one week, Days and Nights; Skies and seasons, land and water; living creature; And humans, were created by God. An example, "Let there be light" then light came out. Everything he thought of happened instantaneously. However, there is no stating how he accomplished all this. Furthermore, there is no evidence that God's breath gave life to a living soul to man. Genesis is in a third person type of writing. Every paragraph start with "And God said..." Overall of the story, God is powerful and perfect. He had done everything w e need. Jinasena is a Jain myth and it is called "There Is No Creator". As the title states, the myth does not believe in god. There is a line say in the myth that set states this, "...if it is complete the individual jiva (soul) is released from the cycle of rebirth to a state of isolated, eternal, and omniscient inactivity." This line is saying that everyone has a soul. However, with the end of each lifetime, another spirit will start again. In another word,...

Juvenile Delinquency Factors Pertaining to Criminal Behavior Essay

This was pounded home in this statement made by Congressman Bobby Scott who said, â€Å"Giving a 10-year mandatory minimum for a second offense fist fight is not going to reduce the chance that someone will be stabbed 16 times when you are not funding any of the programs that are desperately needed to actually reduce juvenile crime†. Juveniles are the future so it is important that we look at cause of criminal behavior within this age group. In order to provide them with outlets that influence their outlook on life and futures and this can only be done if we know what it is that has influenced their life thus far and how we can implement things into their environment that will change their outlook. The first place to look is the family because these are usually the people that the closest and usually the most influential on young people. According to David P. Farrington a Professor of Criminology research has shown that 53 percent of 1,000 adults when asked what they perceived to be the main cause of violence, they agreed it was lack of discipline. And according to Professor Farrington academic research performed in 1997 confirmed the earlier finding. Discipline in the school system was also a factor according to about 15 % of those same adults. The other factors for juvenile delinquency in this research were poverty, violence on television, broken homes as well as drugs and alcohol. This research had to then divide the family influences into six different categories. The first says that delinquent and antisocial children are usually influenced by parents and siblings that are antisocial and or criminal. The greatest influence among 400 males that research was performed on found that males between eight years old and 48 was the convicted father and 63% of those with convicted fathers ended up being convicted as well. In a akin research on families with multiple children it was seen that the older children were convicted more often than younger siblings and only 6% percent of these families ended up with all the children being convicted. What we see here is that home is often times the start of delinquency because problems at home can affect other areas in a child’s life. At times though other areas of the child’s life can affect his or her behavior and may not have anything to do with home life although family may see some differences in the child but not know what has caused the behavior or ignore it thinking this maybe something that the child would out grow. That behavior though at times can a child’s way of crying out for help or attention. Some other things that may trigger delinquency are failure or poor academic levels in school. This can cause frustration and lack of attendance, outburst that can lead to a child being expelled from school. Poor social skills leaving a child feeling unwanted or unable to blend in with his or her peers may cause the child to withdraw and not be able to ask for help or act just the opposite and act out drawing attention to their self or have violent outburst which increases the likely hood that the child will drop out of school or be expelled. Substance abuse is high risk factor for these children in a few different ways. The main thing is that drugs and alcohol tend to cause a temporary relief of the mental or even physical anguish that the child sees their self going through. This usually puts the child in contact with someone that encourages the behavior for the sake of profit but uses guile to fabricate a relationship causing the child to think that he or she is important. This person then enables the addiction to the substances and often times contribute to the illegal behaviors by encouraging the child to sell drugs for him or her. This is done by different means of trickery such as telling them they need a favor done or the main one is tempting the child with the prospect of earning money to help them or their family. This is a great attraction to the child that comes from a broken home and living in poverty for they see it as way of helping to support the family. This type of behavior is also seen in areas that are prone to gangs. They entice the younger child in because they are easier to manipulate. They make the child feel that they are a part of a bigger family and tell them they understand better than their own parents at times. The gang encourages criminal activity to help finance the gang and use violence to protect the gang. This means that the younger the child the easier it is to mold them into their way of thinking. These many times end up with the child being put in danger that may lead to injury and regrettably at times even death. Today we have some programs that help with child delinquency but at times or in some areas there are not enough resources or programs out there to provide better alternatives. This may be the lack of finances and other reasons may include fear caused by gang activity, threats and or violence.

How to Read Literature Study Questions Essay

How to Read Literature Like a Professor Summer Reading Questions 1. A Faustian bargain is more commonly known as a deal with the devil. In a Faustian bargain the protagonist is often offered something that he or she wants, but with a price: he or she must give up his or her soul. It appears constantly in literature in many different forms. Faustian bargains are present throughout One Flew Over the Cuckoo’s Nest because of all the bets McMurphy makes. He goes into the ward knowing about the big Nurse’s power, and basically convinces the patients to follow him in her overthrow. Their price, however, is the risk of being sent to the Disturbed Ward and receiving electro shock treatment or even a lobotomy. In this way, McMurphy can be seen as a satanic figure, who convinces confused and scared patients to bargain what is left of their sanity to take over a Nurse who has ten times more control over their fate. 2. The grammar of literature is what Foster describes as the reader knowing the structure and rules of literature. He says they are a â€Å"set of conventions and patterns, codes and rules† that each reader learns and utilizes as they are reading. They recognize the structure of a paragraph and a sentence and know how to interpret what is on the page in front of them. The reader learns over time this grammar of literature, and he or she develops his or her own way to read and interpret a text. Readers learn the structure of an essay and thus can anticipate with each sentence what is coming next; it is so ingrained in their heads that it comes naturally. We know that a paragraph introduces a topic, gives examples, and then relates those examples back to the initial topic. In this way, the reader has developed a grammar of literature and reading. 3. Professors use symbols and patterns in a multitude of ways in order to interpret a text. Professors of literature, given their extensive memory and knowledge of literature itself, are bound to recognize the patterns and symbols in nearly every text and relate it to another. They read and think symbolically, meaning they recognize everything as a symbol or something of importance until they realize it’s not employed as a symbol. They constantly question everything in a text in order to find the deeper meaning. They see things as they actually exist, but then also look at the same thing to represent something more substantial. Professors are also more adapted to recognize patterns in literature, meaning they see within the detail the patterns it reveals. They are able to look beyond the actual story with the plot and the characters and see the patterns the author has implemented. They are able to recognize which elements are actually substantial enough to aid the work and the plot, and which ones are just detail. Their ability to distance themselves from the work is what makes them able to recognize the symbols and patterns that a regular reader may not recognize in a work. 4. There are five characteristics to a quest. First, there must be a quester. Next, that quester must have a place to go. Third, he or she must have a stated reason to go there. Fourth, there must be challenges and trials during the journey. Lastly, there must be a real reason to go to the place. Usually, the quester doesn’t know it is an actual â€Å"quest†. The real reason for the quest is the most important, and usually has nothing to do with the actual, stated reason. 5. The usual reason behind a quest is self-knowledge. Quests are often educational and provide the quester with a learning experience that aids their self-discovery. The reason for the quester’s youth and immaturity often has something to do with why they are on a quest, and what they end up learning. The only subject that truly matters on a quest is himself or herself. 6. Our questers: McMurphy, Doctor Spivey, and the twelve patients that join them. A place to go: The patients all leave the hospital for a lake to go on a fishing trip. A stated reason to go there: McMurphy wants to teach the boys how to fish and spend some time outdoors. Challenges and trials: The patients first face trouble when they don’t have a signed release form to be allowed to go on the boat, so the captain refuses to take them. McMurphy then takes the captain back to his office to make some phone calls to sort out the problem. While this happens, the other dock boys start heckling Candy, and the patients, not used to seeing others outside of the hospital, don’t stick up for her and defend themselves. They are not used to having enough confidence to stand up for themselves, since they have never had to, and McMurphy is the only one with enough confidence to yell at the dock boys. Next, the men struggle on the boat when trying to catch fish. None of them know how to reel in a line, and McMurphy is too busy with Candy to help them. So, they have to learn for themselves how to catch the fish and wrestle it on their own. The real reason to go: the fishing trip marks an important change in all of the patients. They come back even more bonded together than they were before, and full of confidence and personality. They come back and are confident enough to yell back at the dock boys, and even start sharing real, hearty laughs. It teaches all of them that if you try hard enough, you will get what you want. It also made them less afraid of the real world, and made them appreciate what was on the outside. 7. In the real world, breaking bread together is an act of sharing and peace, since if you’re breaking bread you’re not breaking heads†. 8. A meal scene is almost always symbolic because they are so difficult and boring to write. If a writer puts in a detailed meal scene, it must have some symbolic value since meals are almost never of real importance in a story. The writer must have a pretty good reason to include one in his or her story. The meal scene often has to deal with the relationships, good or bad, between characters, and often offer a turning point or pivotal change in the story during said meal. The typical meal scene is so mundane that for it to be included in a story and take up a lot of writing, it definitely has to have symbolic value. 9. According to Foster, eating in literature may represent a number of things. Firstly, it can represent communion, coming together, and getting along. A meal scene is written to show how characters are getting along or not getting along. It also can be used to form a bond, to find something in common between one character and another. It is a moment and a form of trust. Meal scenes that go wrong are also written for a purpose. Comradeship† at the table is important to convey in a meal scene, whether it is good or bad. The meal scene is vital in portraying the communion of life. 10. A positive communion scene occurs in One Flew Over the Cuckoo’s Nest on the last night McMurphy is in the ward. They bring in some wine and open up the drug closet, and have a good time in the ward with no one on duty. It has symbolic meaning becau se it is one of the few times the patients have an actual fun time together, they bond and realize that life is too short to not have fun. They enjoy being free of stress and restraints and for once feel like real people again. 11. A negative communion happens in Beloved when Paul D comes to visit 124. He comes and visits Sethe and Denver, both of whom he hasn’t seen in many years and wishes to reconnect with them. However, Paul D’s presence makes Denver uncomfortable and left out. Sethe and Paul D sit down for a meal, and Denver feels alienated. No one comes to their house often, and when someone she doesn’t know comes in who takes her mother’s attention away from her, she is clearly angered. On top of that, Beloved decides to frighten them even more. She suddenly shakes the house to the point where everyone has to duck and cover, and frightens Paul D. She decides to make the communion negative and show symbolically her disgust and hatred for unwelcome men. 12. There are a couple essentials to a vampire story. First, there is an older figure (typically the â€Å"vampire†) that is alluring, dangerous, and representing corrupt values. This older figure then focuses on young, beautiful, innocent women, who are often virginal. This vampire then strips away her youth, her innocence, and corrupts her. When he gets her, he himself grows younger and even more alive than before. His energy is renewed and his life continues, while hers is sucked away as she becomes more like him. Since he has taken her virtue, her death and or destruction become inevitable. And most times, the motive often has to do with sex. 13. There are a lot of things other than literal vampirism that vampires and ghosts represent in literature. They can represent selfishness, exploitation, and refusal to respect autonomy. The ghost of Hamlet’s father is there to point out a problem, rather than just be a fright. Edward Hyde represents the dark side of every man. Vampires and ghosts don’t even have to be literal to represent something. They don’t have to appear in visible forms to be considered a vampire or ghost. They are put in a story to scare, haunt, and frighten people, but also to point out problems, teach a lesson, and protect a character. In Beloved, the ghost of Sethe’s murdered daughter embodies the spirit of Beloved as if she were alive. She haunts Sethe’s home and serves as a reminder of what she did. She can be seen as allegorical, as she represents the past haunting the present as a lesson and reminder of the crime Sethe committed. The relationship between Beloved and Sethe is complicated and often an unhappy one. Beloved’s presence is often destructive to Sethe, Denver, and their home. She creates instability in their household as well as within both women of the house. Though she is dead, she is ever-present, and helps develop the characters of Sethe, Denver, and Paul D. She represents pain and misfortune, but also guidance and hope. 14. Paul Berlin, the protagonist in Going After Cacciato, embodies an author’s â€Å"creative process† in many ways. His story is compiled from many other stories, meaning that all the stories ever written all stem from one story.

Proactive Organizational Tips for Messy Student Desks

Proactive Organizational Tips for Messy Student Desks Neat desks are essential to help students build constructive study habits, organizational skills, and a clear mind for concentration. That positive feeling you get when you walk into your classroom in the morning and things are all straightened up from the afternoon before it works the same for students. When they have clean desks, they will feel good about school in general and the whole classroom has a better atmosphere for learning. Here are four organizational issues and the simple strategies that will help students keep their desks as neat and structured as possible.  Ã‚   1. Little Stuff is Everywhere The Solution: A plastic shoebox-size container, which can be bought at any big box store like Wal-mart or Target, is a cheap and lasting solution that keeps all of the little things together in one place. No more pencils, calculators, or crayons stuffed in the nooks and crannies of a desk. Once you buy a set of these containers, theyll last you years (and save you at least a dozen or more gray hairs!). 2. Loose Paper Explosions The Solution: If you look in your students desks and see countless loose papers flying all around, then you need a tried and true solution the Neat Folder. Its simple just give each student a folder in which to keep the loose papers that they will need again in the future. With all of the items consolidated, the inside of the desk assumes a more organized and sophisticated look. (Well, at least as sophisticated as a 30-year-old school desk can look.) Give students each color-coded folders that correlate with each subject. For example, a blue folder is for math, a red folder is for social studies, green  is for science, and orange is language arts. 3. There Isnt Enough Room The Solution: If there are simply too many items in your students desks, consider keeping some of the less-used books in a common area, to be distributed only when needed. Take a critical look at what youre asking children to store in their desks. If its too much for comfort, alleviate some of the items in competition for precious storage space. Every little bit makes a difference, so try creating space on the bookshelf just for student textbooks. This will help alleviate all of that extra clutter in their desks. 4. Students Just Wont Keep Their Desks Clean The Solution:  As soon as its tidied up, it transforms back into its formerly disastrous state. Some students just cant seem to keep their desks clean for any length of time.  Consider implementing a program of consequences and/or rewards to motivate the student to maintain the proper standards of desk cleanliness. Maybe the student has to miss recess, maybe he or she can work towards earning a privilege. Find a plan that works for that student and stick to it. Edited by Janelle Cox
