Clostridium Botulinum Research Paper Example | Topics and Well Written Essays - 750 words
Clostridium Botulinum - Research Paper Example Furthermore, these spores may at times get into the human gastrointestinal system and can be able to withstand the hostile environment. Once the spores reach the colon, some germinate to produce the bacteria, but in cases of adults, often cannot withstand competition from the normal microflora. However, in infants, due to lack or few existing microflora, these organisms often take advantage of multiplying and causing infections through production of botulinum toxin. In relation to botulinum toxin, there exist several types: Toxin A, B, C, D, E, F, and G. There are only types A, B, E and rarely F, which mostly cause the flaccid paralysis symptom in humans. The other types often cause disease in animals. Botulinum toxin often results to a condition called botulism. Botulism This is a paralytic illness that results due to the botulinum toxin. Botulinum toxin is a neurotoxin. People often get the toxin in their bodies via ingestion of contaminated foods already having botulinum toxin, th rough the bacteria infecting a wound and producing the toxin, and through consuming spores that produce the bacteria that finally produces the toxin to cause the condition (Smith 34). From the three modes of in which botulinum toxin could get into the human body system, one could identify three types of botulism namely; food borne botulism, wound botulism and infant botulism. Botulism is a fatal condition and all times considered medical emergencies. Botulism neurotoxins often prevent neurotransmitters in the nervous system from functioning properly. In fact, they usually inhibit the functioning of the motor control. A patient often exhibits paralysis stating from top to bottom, beginning from the eyes, face as it moves down the neck, chest, upper limbs and lower limbs (Shneider, Chang & Goodrich). Botulism often produces symptoms 12 to 72 hours on ingestion of contaminated food. Symptoms of botulism generally appear 12 to 72 hours after eating contaminated food.à Infant botulism This type of botulism accounts for the most number of cases reported of botulism. It often affects children due to having few or lacking microflora in their colon (Hauschild 40). In homes, improperly canned foodstuffs often the spores of the bacteria, which upon ingestion by infants, result to overgrowth of the bacteria in the colon leading in production of botulinum toxin. Symptoms In infant botulism, symptoms exhibited include poor appetite, lethargy, constipation, drooling, weak cry, poor feeding, paralysis and drooling eyelids. The general symptoms which botulism poisoning produce entail fatigue, nausea, vomiting, double vision, dizziness, dry skin, dry throat, dry mouth, difficulty swallowing, slurred speech, body aches, muscle weakness, and paralysis (Canadian Food Inspection Agency). Treatment Treatment can be instituted in the early period before the toxin takes toll of the nervous system completely. An antitoxin is often administered in such cases (Emmeluth & Alcamo 67). T he antitoxin functions by blocking the circulating botulinum toxin In the blood thereby limiting its action. This form of treatment only prevents the worsening of the patientââ¬â¢s condition. Patients from such incidences often take several weeks to recover completely from the effect. Prevention In relation to the three types of botulism and the mode through which the toxin gets to enter the human body, preventive measures can be

Anesthetic Management of the Patient with Aortic Stenosis Essay
Anesthetic Management of the Patient with Aortic Stenosis - Essay Example Surgery is indicated in many of the cases in order to repair or replace the diseased valve. Therefore, it is the purpose of this paper to investigate the current anesthetic management of this disease, from preoperative to postoperative care. This paper will describe the basic anatomy and physiology of the heart, in particular, the aortic valve. The pathophysiological changes in the aortic valve and the heart will also be discussed. The heart is a hollow muscular organ that is somewhat pyramid-shaped and lies within the inferior mediastinum (3). It is covered by a fibroserous sac called the pericardium, within which pericardial fluid fills the space between the serous and fibrous layers. The pericardial fluid acts as a lubricant to prevent friction during the contraction of the heart. The pericardium is not very distensible, and therefore it strongly resists a large, rapid increase in cardiac size. Hence, the pericardium also prevents sudden overdistention of the chambers of the heart (4). The heart is divided by a vertical septa into four chambers: the right and left atria, which occupy the upper chambers and the right and left ventricles, which occupy the lower chambers. ... Although most myocardial cells are able to perform both these functions, the vast majority is predominantly contractile cells (myocytes) and a small number are specifically designed as electrical cells. The latter, collectively known as the conducting system of the heart, are not nervous tissue but modified myocytes lacking in myofibril components. They have the ability to generate electrical impulses which are then conducted to the myocytes, leading to contraction by a process known as excitation-contraction coupling (5). In order to produce a synchronized contraction, there must be a normal spread of electrical activity within the heart. Depolarization is initiated in the sinoatrial node (SA) node hence it is known as the pacemaker of the heart. It sets the contractions of the heart at a rate of 60-100 beats per minute. From the SA node, the electrical impulse travels to the atrioventricular (AV) node and then propagates through the Bundle of His. From the top of the septum, the wa ve of depolarization spreads in the rapidly conducting Purkinje fibers to all parts of the ventricles (6). Between the atria, ventricles and great blood vessels arising from the heart (aorta and pulmonary artery) are valves, which are made up of cusps or leaflets to prevent backflow of blood, ensuring a one-way conduit of blood through the chambers and to the pulmonary and systemic circulation. There are four valves: two semilunar valves (aortic and pulmonary valves) and two atrioventricular valves (tricuspid and mitral valves). All of these valves have 3 cusps except the mitral valve which has two cusps. Unoxygenated blood from the superior and inferior vena cava and coronary

Now is the time for this nation to decide and prohibit any illegal entrance into its homeland. We need to focus on more serious technological advancement instead of involvement in useless issues and conflicts as well as leaving an additional burden over border and security agencies. The cost and benefit analysis and studies on legal immigration and illegal entrances are now mature and should be dealt accordingly. Another aspect of the debate over legal and illegal immigrants is that more and more Americans are now growing aggressive and blunt in their outrage against illegal immigrants. This may cause damage to our national harmony and peace of mind no matter how liberal we are. Schor states, ââ¬Å"We are running out of resources and available tax dollars and yet we have people who want more immigrations. This is dumb. I do not feel that my tax dollars should be spent on illegal immigrants.â⬠The sentiment against illegal immigrants gets more and more intensified whenever our civic requirements are not aptly fulfilled for US citizens and legal immigrants. Health care, transportation, welfare, education, utilities, natural resources etc. there is drain everywhere and there a staunch disagreement everywhere on immigration policies that supports legalization of illegal immigrants.

Planning Transitions to Prevent Challenging Behavior Essay
Planning Transitions to Prevent Challenging Behavior - Essay Example At first glance, the articles seem to be different in the kind of content and message that they are sending out to the intended audience. However, on closer look, one can comprehend that the thrust of both articles is about the ways in which teaching methods can be improved to make a difference in the way children are taught. Both articles talk about teachers making decisions in the daily interactions with their wards. The difference in the articles is the way in which each article suggests different methods to achieve the common goal of making the students understand what is being taught and how teachers can be role models for their students. The article about ââ¬Å"Teaching children what we want them to learnâ⬠concentrates on the different ways in which children pick up things from their teachers by looking up to them as role models as well as imbibing values and qualities from the teachers. The article makes the point about how kids at such a young age are impressionable and hence are prone to look up to their teachers in a manner similar to that they do with their parents and hence the teachers have to extra careful in the messages that they send to the students. These include verbal and non-verbal cues as well as the kind of lessons that the teachers pick for their children every day. This article also mentions the subtle difference between the statements that express a reflective desire to inculcate learning in the children as opposed to expecting the children to learn better. For instance, there is a huge difference in taking personal responsibility as a teacher and ensuring that the children get to learn and think about the children as being responsible for their education. One is reflective (as mentioned above) and the other is reactive.Ã

Explain what the digital divide is; in your answer discuss the Research Paper
Explain what the digital divide is; in your answer discuss the advantages and disadvantages of improving the digital divide - Research Paper Example What does it mean? How did it happen? Does it have any positive or negative effect on our society? What benefits can be had from promoting a digital divide? Should the digital divide be promoted within our society as something that should be supported or not supported? These are but a few of the questions that I am looking forward to answering within the next few pages. I would like to start off this paper by presenting the readers with a basic discussion of the digital divide and its meaning. While the economic divide pertains the method by which the people of the world are separated by the amount of money that they have, the digital divide separates people in terms of their existing or non-existing access to the internet and other forms of communication technology. According to experts, the digital divide exists as a barrier between the urban and rural areas (Rouse, 2005). Upon closer inspection, one will come to the realization that the digital divide, also known as the digital split, refers not only to the people who have easy access to the internet and those who dont, but also among those who have or dont have access to information and communications technology. The term digital divide was then coined, in the 1990s in order to help explain the complex scenario. Due to the globalized market that exists between countries, the presence of the internet and other forms of telecommunication that can help ease the transfer of business information has become one of the utmost important business tools in our era. However, not all countries have state of the art information and communication technology infrastructures in place so the digital divide has already gone beyond borders, thus creating what is now known as the Global Digital Divide. Therefore, the digital divide is not limited to the social or economic statues of people alone. It also includes the members of society who use almost obsolete computers on infantile internet

Business Article review Essay Example | Topics and Well Written Essays - 500 words
Business Article review - Essay Example The Department of Labor reported that unit labor costs increased by 1.4% while inflation-adjusted compensation rose to only 0.4 %. The higher rate of increases in productivity relative to the mount in hourly wage indicates that "companies are still able to keep a significant share of productivity gains for themselves and their investors." An implication of this is that companies are able to keep a larger share of their revenue as gross profits which can dampen the possibility of inflation as they allow companies to absorb more costs. However, the article also recognized that as companies have strong pricing power, they are hesitant in absorbing higher input costs but are inclined to pass these costs to consumers. The decline in the number of unemployed is indicative of a strong job market (Whitehouse). The article revealed the interrelation of different macroeconomic variables in the society as well as showed how the economic climate affects the position and decision making of business entities. The concepts such as inflation, productivity, and employment levels which are presently tackled in the class and their relationships are more elucidated and understood in the business article. Theoretically, labor productivity and wages are closely li
