The new advancements in Cloning and the Ethical debate surrounding it

Introduction Cloning is the generation of cells, tissues, organs, organ systems or totally independent organisms from DNA. This article will discuss the latest developments, benefits and ethical and views as regards to cloning.Advertising We will write a custom research paper sample on The new advancements in Cloning and the Ethical debate surrounding it specifically for you for only $16.05 $11/page Learn More Types of cloning There are three types of cloning. Molecular cloning involves use of DNA segments in areas of interest to produce specific products of DNA transcription and this has proven useful in recombinant DNA to produce many therapies like insulin, tissue plasminogen activator and erythropoietin. Cellular cloning involves use of somatic cells to produce a cell line identical to the original cell, and this can be used to produce therapies like those of molecular cloning. Blastomere separation is advanced in that reproductive cells are used to produce independent organisms (Anon, n.d.). Experiments done so far Many advances have been made in cloning so with more animals being cloned. The Rhesus monkey was cloned in 2000 January by embryo splitting and it was known as Tetra. In 2001, an endangered species was cloned called Gaur. Alpha and Beta are the cattle that were cloned in 2001 and 2005 respectively and they were males. The CopyCat was the female cat to be cloned in 2001. In 2004, Little Nicky was the first cat to be cloned for commercial purposes. The first dog to be cloned was Snuppy in 2005. A rat that was first cloned in 2003 and it was named Ralph. Idaho Gem is the name of the first mule to be cloned in 2003. In May 2003, the first horse was cloned named Prometea. The first water buffalo to be cloned was named Ssmrupa in 2009 February but it died after five days because it was infected. The same year, Injaz became the first camel to be cloned(Arnold, 2009). Views on cloning today Attempts to clone human cells fac e many ethical, religious and legal challenges today. Another major challenge is the difficulty in cloning human cells. Never the less, research is going on in various institutions to improve the methods and thus the outcome of cloning since it’s potentially useful in treatment of many medical conditions. The breakthroughs of cloning Treatment of leukemia Normal bone marrow precursors are cloned and placed in the bone marrow cavity of the leukemic patient.Advertising Looking for research paper on health medicine?

Treatment in heart attack patients In patients with acute or chronic myocardial infarction, cells can be cloned and then be placed in the ischemic areas. New Vaccines Vaccines can be made by developing cancerous cells which can not repli cate and injecting them to subjects. This can potentially generate memory in the immunity so that on second exposure, these cells are destroyed by the immune system. Another way of using cloning in vaccination is by using DNA recombinant technology where microbial DNA is used to produces toxins, which are detoxified, while retaining their immunogenicity, and introducing them in a subject, who will eliminate the microbes on second exposure. Treatment of Parkinsonism This has been tried in mice where dopamine producing cells are cloned and then injected into mice with Parkinsonism. Behavioral symptoms of the disease improved in the mice because the missing dopamine was produced by these cells. There is hope that this is possible with humans (Randerson, 2008). Life saving strategies Cloning has been supported by many scientists because of these potential benefits. Other major areas of application in cloning are as follows. Organ transplantation Parts of an individual can be cloned to p roduce large tissues which can be transplanted to another part of the same individual. This has an advantage over transplantation from another individual which leads to graft rejection. Infertile individuals, cancer and plastic surgery Cloning processes involve switching on and off of cells, a principle which can be exploited in switching of cancerous cells. Through cloning, a vaccine of cancer may be made as previously noted. Infertile people can father by either using their reproductive cells or cloning their somatic cells and introducing them to a surrogate. Plastic surgery done using cloning has a great benefit as compared to other methods because features of the patient can be retained with no fear of graft rejection.Advertising We will write a custom research paper sample on The new advancements in Cloning and the Ethical debate surrounding it specifically for you for only $16.05 $11/page Learn More Other applications Cloning can be used to test f or genetic diseases. Nerves can be grown to enable high quality medication. Cloning can be used to grow nerves which can be replaced in individuals with spinal cord injury. Liver failure and renal failure can be cured by cloning by replacing the diseased cells. Tay Sachs disease can be prevented by eliminating genes carrying the disorder. Breast implants and soft tissue replacement can be done using cloned tissues from the same individual to eliminate changes of host verses graft disease. Skin can be produced for use as skin flaps in patients with severe burns; lung tissue can be cloned as well. Diseases which seemed to have no cure like Alzheimer’s disease, Diabetes Mellitus, Heart failure arthritis and other degenerative diseases can be approached in this manner (Smith, 2002). Criticisms Reasons for opposition to cloning According to ethical and religious groups, the drawbacks on cloning are many. On average, there is only 1-10% viability of all offspring that were cloned f rom embryos. It has been shown that cloned animals have a higher risk of cancer, infections, mental and physical difficulties. The animals that have been cloned have been seen to die unexpectedly, unpredictably and for unknown reasons. Human cloning is specifically opposed because it is believed that a growing human also needs emotional and intellectual development, which can not be provided by cloning. Genetics Fact Sheet 1 indicates that a person is a product of his or her genetic make up and the environment such that a person cloned from another is not a duplicate. Social relations, responsibility and parenthood of the cloned human are difficult to achieve, which pose a challenge to cloning (BarlowSaleh, 2007). Ethical groups There was a worldwide condemnation of attempts to clone a human being in 2003 when Clonaid biotechnology group claimed to have cloned a baby who they named Eve. They were opposed mainly because of the reasons above. There are many policies which have been la id to regulate cloning especially in the utilization of the embryos (BarlowSaleh, 2007). Conclusion My personal view and opinion Cloning has various pros and cons, whereas it can be a life saving process, it may also have many deleterious effects on the human race. Biologists and doctors should not rush into cloning humans. There is need to carry more experiments with care and the results analyzed to perfect the science and eliminate the disadvantages of cloning and then educate the lay world on the benefits of cloning.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Recap Cloning is the generation of body tissues from DNA. This procedure has many potential applications in various sectors of health. In spite of that, it has been opposed by many ethical groups because of the risks involved and others because of myths and traditional beliefs. With care and effort, these properties can be exploited to develop vaccines, treat various diseases, help in surgery, and even stop the aging process. Research experiments should be furthered The only way to eliminate most of the risks associated with cloning is through furthering the experiments in different species and comparing the results. Biologists should come up with effective machines which do not affect the genetic composition in the embryo as this would reduce the disabilities and mutations seen in cloned animals. Through cloning, many vaccines can be developed which would not otherwise be available. More experiments should be done to develop more vaccines to various diseases. More experiments shoul d be done in order to find treatment of endocrine system diseases as has been seen in diabetes mellitus with insulin. Auto grafts do not induce immunogenicity in an individual. More experiments should be done to exploit this fact by cloning cells to form tissues or even organs from the same patient and then surgically introducing them to the area of defect. Cloning experiments should be furthered to discover other benefits of cloning which are not yet known. References Anon.(n.d.). The Science and Application of Cloning. Web. Arnold, P. (2009).

Cars Then and Now essays

Cars Then and Now essays The automobile is the most important means of personal transportation for many people around the world. People depend on there cars and trucks to get them to work, run errands, to visit friends and The origin of automobiles can be traced to Europe. But it became a major form of transportation in the United States first. In the early 1900s, Ransom E Olds, Henry Ford, and other automobile pioneers began mass production. Although some people disliked the horses carriage many welcomed the introduction of the new machine because it would replace horse drawn carriages. The automobile gave people freedom to live, work and travel whenever they wanted. It ended the lonely farm lives of families that were to far from a big city to ride a horse there. The automobile brought along motels, gas stations, shopping centers, theme-parks, superhighways, and drive through restraunts.These industries being brought into the economy lead to a major increase in strength of the The development of automobiles has had an enormous effect on the way people live throughout much of the world. Probably no other invention, discovery, or technology advance has created greater The automobile has given people incredible freedom and movement. It enables people to decide where they want to go and when. It influences how people work and how, live and spend there leisure time. The striking change in peoples lives created by the automobile started in the United States and have since spread over much of the globe, especially in developed countries. They are also becoming increasingly popular in developing countries and are reshaping the life style of the people that live When the first automobiles were produced, only the well-to-do could afford them. Soon, however, prices declined as production increased in the response to the growing demand. The lowe ...

College Athletes Should be Paid to Play Essay Example | Topics and Well Written Essays - 1000 words

College Athletes Should be Paid to Play - Essay Example Some argue that athletes are paid by virtue of their scholarship and that is sufficient reimbursement for their services. Putting aside for the moment that athletes that participate in the more popular sports earn millions of dollars for the university and that other students reap these benefits as well, athletes are denied the same lack of restrictions to earn while they learn and as a result should be somewhat compensated. The NCAA alone makes hundreds of millions of dollars every year from the men’s March basketball tournament. The bowl games that follow the regular football season supply the conferences with revenues of many million each winter. Now add up ticket and concession proceeds, corporate sponsorships and money gained from merchandise sales that without the presence of sports would not be funneled into a university annually. The athletes know that they generate literally many billions of dollars for their schools, yet are not allowed to earn even pocket change whi le at school, giving their all for ‘ole State U. Athletes are allowed only the most meager of an existence under NCAA regulations. Meanwhile, they witness other students with money enough at least for an occasional date and their coach earning a multi-million dollar salary but know that they are the ones that make the greatest sacrifices. The NCAA reports that of the 1000 schools in its membership, only 40 earn a profit each year, all of which are Division I-A institutions and have either a successful football or basketball program. Though revenues continue to rise for these select schools; the remaining schools are suffering growing deficits. In most cases, schools utilize money gained from its more successful and thus profitable sports programs to fund the other sports activities at the school such as the bulk of women’s athletic programs. The vast majority of schools could not afford to pay for programs that did not pay for themselves if not for the athletes that put ‘butts in seats.’ These athletes are producing enormous revenues that not only pay for other sports programs but pump money into the general scholarship fund. Athletes should be compensated at least minimally but not just athletes that are involved in revenue producing sports. All college athletes should receive a modest salary because all of them allocate so much of their time to their particular sport. Even the non-profitable sports programs provide publicity to the institutions in amounts impossible to quantify. â€Å"There are also student-athletes who have to leave school early because they do not have enough money to continue, or to pay their bills and leaving school for a career in professional sports is an easy way of making money.   The argument is that if student-athletes get paid, they will remain in school and complete their education† (Meshefejian, 2005). When a student-athlete or their family is experiencing financial problems as is the case in m any situations, the pressure to quit school and pursue a professional career is immense. What would motivate an athlete in this predicament to stay and finish school if they were offered even a minor league contract or a backup role at the major league level? Many examples exist where athletes opt to turn professional, then are out of a job within a year or two and cannot return to school because they can no longer be offered a scholarship. If they could have justified, financially speaking, staying in school, many may have graduated and whether or not they succeeded at the professional level, they would have had a diploma and therefore a solid career and a

Disrupting the Recruitment Process to Exploit Weaknesses in Terrorist Research Paper

Disrupting the Recruitment Process to Exploit Weaknesses in Terrorist Organizations - Research Paper Example This paper explores recruitment practices in the global Jihad as they play out in America and Europe. Whereas the focal point of the discussion is terrorism, the paper explores a distinct form of contemporary terrorism, Global Jihad, which embodies religiously inspired conflicts with a global vision. Nevertheless, the paper does not necessarily centre on terror groups with nationalistic or secular motives. The global Jihad is entangled with individuals, organizations, and ideologies from the Middle East, South East Asia, Central Asia, and North Africa. There are four distinct levels of commitment within terrorist organizations. These include passive supporters, active supporters, cadre, and leaders. Although all play a critical part in the running of the terrorist organizations, the cadre can be singled out to be the level that has a phenomenal influence in the recruitment process. Cadre encompasses the nucleus of active members engaged in the overall running of the terrorist operations inclusive of recruiting new members. Terrorist organizations employ both hierarchical and networked structures of organization. Islamic radicalization can be considered as the lynchpin to homegrown terrorism, especially in the West. Delegitimizing radicalization is arguably an effective way of disrupting recruitment process. ... Most recruitment processes into terrorist organization feature aspects such as targeting of the alienated and marginalized, spiritual quest, radicalization, gradual seclusion and cell formation, adoption of violence as a legitimate political means, linkage with a gatekeeper, and eventual operation of the cell. Terrorist recruitment cells can be delimited into four separate cells; management cell, information gathering cell, preparation cell, and execution cell. Disrupting Recruitment Process Most international terrorist organizations are actively engaged in recruitment of Westerners into terrorist organization via facilitation of travel to foreign training camps and mounting grounds. Foreign terrorist organizations have shifted their strategy from passive influence of western radicals into directly motivating, inspiring, and training, especially through internet-based propaganda. Recruitment of Western radicals has worked for foreign terrorist organizations as they can conceal the id entity as the recruits hold â€Å"clean† citizenship. The employment of homegrown terrorist cells has complicated the ability to infiltrate terrorism recruitment rings (Cortright & Lopez, 2007). The four principal ingredients to a thriving terrorist’s organization include recruitment, motivation, funding, and haven. Terrorism is affected by interplay of factors such as a haven, leadership, and the underlying conditions within the society. Terrorist organizations leaders avail motivation, mobilization, and organization functions within the organizations. In addition, leaders within terrorist organizations act as principal sources of propaganda besides acting as symbolic figureheads

Evidence of Bad Character Case Study

Evidence of Bad Character Case Study 1.That Z had sex with T D H The evidence that Z had sex with T D H can be admitted with the agreement of all the parties[1]. However it is unlikely that Z would agree that this evidence could be admitted therefore that X would have to rely on one of the other provisions of section 100 (1) of the Criminal Justice Act 2003 in order to admit the evidence. Section 100 (1) of the Criminal Justice Act 2003 stipulates, â€Å"Evidence of the bad character of a person other than the defendant is admissible if and only if: It is important explanatory evidence, It has substantial probative value in relation to a matter which – is a matter in issue in the proceedings, and is of substantial importance in the context of the case as a whole, or all parties to the proceedings agree to the evidence being admissible Therefore it is likely that Z will try and admit this evidence under s100(1)(b) arguing that it has substantial probative value in relation to a matter that is either a matter in issue in the proceedings or that is of substantial importance in the context of the case as a whole. In order to determine whether or not the evidence has substantial probative value case law prior to the enactment of the Criminal Justice Act 2003 should be considered where it was considered that such evidence could be admitted if it was â€Å"striking similarity[2]†and of â€Å"sufficient probative force to overcome prejudice.[3]† It is likely that this evidence will be admitted. 2.That Z was convicted of wasting police time The evidence that Z had been convicted of wasting police time could again be admitted if both parties agree to the evidence being admitted. However it is unlikely that Z would agree that this evidence can be admitted therefore that X would have to rely on one of the other provisions of section 100 (1) of the Criminal Justice Act 2003 in order to admit the evidence. Section 100 (1) of the Criminal Justice Act 2003 stipulates that â€Å"evidence of the bad character of a person other than the defendant is admissible if and only if: It is important explanatory evidence, It has substantial probative value in relation to a matter which – is a matter in issue in the proceedings, and is of substantial importance in the context of the case as a whole, or all parties to the proceedings agree to the evidence being admissible Therefore it is likely that Z will try and admit this evidence under s100(1)(b) arguing that it has substantial probative value in relation to a matter that is either a matter in issue in the proceedings or that is of substantial importance in the context of the case as a whole. In order to determine whether or not the evidence has substantial probative value case law prior to the enactment of the Criminal Justice Act 2003 should be considered, as above and in consideration of that evidence it is unlikely that the evidence will be admitted. This does not appear to be of substantial importance and it is likely that the jury could reach the right conclusion without hearing this evidence. 3.That W is a lesbian who is prejudiced against men The evidence that W is a lesbian who is prejudiced against men can be admitted with the agreement of all the parties[4]. However it is unlikely that W would agree that this evidence could be admitted therefore that X would have to rely on one of the other provisions of section 100 (1) of the Criminal Justice Act 2003 in order to admit the evidence. Section 100 (1) of the Criminal Justice Act 2003 stipulates, â€Å"evidence of the bad character of a person other than the defendant is admissible if and only if: It is important explanatory evidence, It has substantial probative value in relation to a matter which – is a matter in issue in the proceedings, and is of substantial importance in the context of the case as a whole, or all parties to the proceedings agree to the evidence being admissible Therefore it is likely that Z will try and admit this evidence under s100(1)(b) arguing that it has substantial probative value in relation to a matter that is either a matter in issue in the proceedings or that is of substantial importance in the context of the case as a whole. On this basis it is unlikely that this evidence will be admitted. 4.Psychiatric evidence in respect of Y The evidence that Y is suffering from Potipahr’s Wife Syndrome can be admitted by agreement by the parties. [5] However it is unlikely that Y would agree that this evidence could be admitted therefore that X would have to rely on one of the other provisions of section 100 (1) of the Criminal Justice Act 2003 in order to admit the evidence. Section 100 (1) of the Criminal Justice Act 2003 stipulates that â€Å"evidence of the bad character of a person other than the defendant is admissible if and only if: It is important explanatory evidence, It has substantial probative value in relation to a matter which – is a matter in issue in the proceedings, and is of substantial importance in the context of the case as a whole, or all parties to the proceedings agree to the evidence being admissible X will need to argue that the evidence is important explanatory evidence. Evidence is â€Å"important explanatory evidence† for these purposes if â€Å"(a) without it, the court or jury would find it impossible or difficult properly to understand other evidence in the case, and (b) its value for understanding the case as a whole is substantial[6]. Except in relation to evidence of conduct, which is alleged to be similar to matters in dispute at the trial, evidence of witness’s bad character may not be adduced without the leave of the court[7]. Section 100(3) identifies certain factors to be taken into account by the trial judge, alongside any others considered relevant, in exercising his discretion to grant leave to allow bad character evidence to be given. Such factors include the number of relevant incidents, the lapse of time, and other common sense considerations relating to similarities between past and present conduct and questions of contested identity. Therefor e such evidence will only be admitted if it bears substantial probative value, and the court grants leave. It would therefore be concluded that in this instance that the evidence would be admitted. 5.Previous evidence of V Assuming as discussed above that the X is not successful in admitting any of the evidence (as if he is this will mean that the evidence of his bad character and previous convictions will automatically be admitted) the Criminal Justice Act 2003 contains a dedicated scheme of rules to regulate the admissibility of evidence of the accused’s extraneous misconduct in s101 (1). These rules are different from those rules that exist for the admittance of other witness’s previous character. In criminal proceedings evidence of the defendant’s bad character is admissible if, but only if – all parties to the proceedings agree to the evidence being admissible, the evidence is adduced by the defendant himself or is given in answer to a question asked by him in cross-examination and intended to elicit it, It is important explanatory evidence, It is relevant to an important matter in issue between the defendant and the prosecution It has substantial probative value in relation to an important matter in issue between the defendant and a co-defendant, It is evidence to correct a false impression given by the defendant, of The defendant has made an attack on another person’s character Therefore this evidence can be admitted by agreement by the parties however this is unlikely. Therefore it is likely that the prosecution will attempt to admit the evidence under sections c and d and this are provisions, which are concerned with similar fact evidence. One significant dimension of the â€Å"similar facts† cases concerned the dangers posed by deliberate collusion between witnesses or innocent cross-contamination of their evidence. In determining the admissibility of evidence of the accused’s misconduct in the first instance, however, section 109 obliges the court to treat the evidence as true, unless â€Å"it appears, on the basis of any material before the court (including any evidence it decides to hear on the matter), that no court or jury could reasonably find it to be true[8]. Therefore given the similarities between the previous incident and the current one it is likely that this information will be allowed to be admitted into the current proceedings. The reason for this is that the evidence can either be considered to be important explanatory evidence or alternatively that it is relevant to an important matter in issue between the defendant and the prosecution 6.X’s previous conviction of Exposure The CJA 2003 contains a dedicated scheme of rules to regulate the admissibility of evidence of the accused’s extraneous misconduct in s101(1): In criminal proceedings evidence of the defendant’s bad character is admissible if, but only if – all parties to the proceedings agree to the evidence being admissible, the evidence is adduced by the defendant himself or is given in answer to a question asked by him in cross-examination and intended to elicit it, It is important explanatory evidence, It is relevant to an important matter in issue between the defendant and the prosecution It has substantial probative value in relation to an important matter in issue between the defendant and a co-defendant, It is evidence to correct a false impression given by the defendant, of The defendant has made an attack on another person’s character Therefore this evidence can be admitted by agreement by the parties however this is unlikely. Therefore it is likely that the prosecution will attempt to admit the evidence under sections c and d and this are provisions, which are concerned with similar fact evidence. One significant dimension of the â€Å"similar facts† cases concerned the dangers posed by deliberate collusion between witnesses or innocent cross-contamination of their evidence. In determining the admissibility of evidence of the accused’s misconduct in the first instance, however, section 109 obliges the court to treat the evidence as true, unless â€Å"it appears, on the basis of any material before the court (including any evidence it decides to hear on the matter), that no court or jury could reasonably find it to be true[9]. Section 107 where evidence of the accused’s bad character has been admitted into the trial without the accused’s agreement, under section 101(1) paragraphs (c)-(g), and the court is satisfied at any time after the close of the prosecution’s case that (i) that evidence is contaminated such that (ii) a conviction would be unsafe, â€Å"the court must either direct the jury to acquit the defendant of this offence or, if it considers that there ought to be a retrial, discharge the jury†. Either way, proceedings will not be allowed to continue if it emerges during the course of the trial that material evidence of bad character has been contaminated. A previous conviction can be admitted as evidence of propensity if it falls into either: (i) one of the categories of offences; or (ii) the statement of the offence in a written charge or indictment would be the same. Thus, a person who has been convicted of actual bodily harm and is now charged with actual bodily harm will fall into the second category (same description)-but a person who has been convicted of theft and is now charged with burglary would not. However, the Home Office will introduce two sets of categories of offences-the first broadly comprising all Theft Act offences, the second comprising sexual offences involving sexual contact with children. Therefore given the similarities between the previous incident and the current one it is likely that this information will be allowed to be admitted into the current proceedings. The reason for this is that the evidence can either be considered to be important explanatory evidence or alternatively that it is relevant to an important matter in issue between the defendant and the prosecution 7.Directing the Jury Because of the statutory grounding of the criminal evidence rules the rules on directing the jury, in relation to similar fact evidence and evidence of bad character have altered somewhat. The provisions that we are concerned with here are contained within Section 107 where evidence of the accused’s bad character has been admitted into the trial without the accused’s agreement, under section 101(1) paragraphs (c)-(g), and the court is satisfied at any time after the close of the prosecution’s case that (i) that evidence is contaminated such that (ii) a conviction would be unsafe, â€Å"the court must either direct the jury to acquit the defendant of this offence or, if it considers that there ought to be a retrial, discharge the jury†. Either way, proceedings will not be allowed to continue if it emerges during the course of the trial that material evidence of bad character has been contaminated. Finally, there is a power for the court to discharge the jury and either direct an acquittal or order a retrial if a judge, having admitted evidence of bad character, later decides that such evidence was contaminated. Contamination is defined in terms of evidence that is false or misleading in any respect, as a result of the witness who gave the evidence either having agreed to give false evidence, or being affected by hearing other evidence in the case. It seems these provisions are aimed particularly at allegations of multiple sexual abuse where other allegations are, on occasion, felt to be the consequence of collaboration by different witnesses. In such cases it would be open to the judge to cure the problem by direction to the jury, but where it is felt that direction is inadequate and any subsequent conviction would be unsafe, the judge is empowered to discharge the jury. In conclusion therefore if the judge is satisfied with the evidence and there is no evidence of contamination or collusion then this evidence of the defendant’s previous bad character will be admitted.

Essay --

Being born and brought up in Afghanistan doesn’t go particularly smoothly, especially when compared to the contemporary standards of the UK. Aside from on-going war, many outbreaks of diseases have occurred, which I have first-hand experience of. At the age of 10 I contracted the water borne disease of cholera, due to our village’s water supply being heavily contaminated. I fully recovered, however the experience left me with a spark of inquisitiveness into the importance of maintaining a clean water supply and not allowing it be polluted. Today, chemical engineers are at the vanguard of maintaining clean water supplies to where they are abundant and establishing clean water supplies to where they are scarce, alongside their many other contributions to modern day scientific breakthroughs. Having studied Physics, Maths and Chemistry, I understand the obligation chemical engineers feel to contribute to the ever expanding global society. I had already thoroughly enjoyed these subjects at GCSE level and it only seemed right to me to pursue them at a higher level; when deciding my A-Level...

Review the treatment for TB (look in Lewis), including medications, length of treatment, evaluation of treatment plan, who is most likely to get TB infection, and side effects of the medications Medications: aggressive TB treatment: four drugs for 6 months, (INH, rifampin [Rifadin], pyrazinamide [PZA], and ethambutol) Newer: rifamycins, rifubin, rifapentine, first line for special situations Length of treatment: 6 months- 1 YearEvaluation of treatment plan: resolution of the disease, normal pulmonary function, absence of any complication, no transmission of TB, Most likely to contract: Asians have the highest TB rate, followed by Hawaiians and pacific islanders. African Americans are the highest rate inside the US. (45%) Higher rates of TB infections with patients with HIV infections Side effects of meds: alcohol increases hepatotoxicity of INH, monitor liver function.PZA may not be included in initial phase (due to liver disease or pregnancy) 4. Review the care of a patient with lung surgery, including chest tube management To keep lung inflated & Drain fluid from interpleural space How do you know if collapsed lung: Blood gases, Chest X-ray, Vital signs, Color Air leaks – bubbling in water chamber: check your tubes for air leak & make sure they’re always free of kinks. Don’t milk the chest tube (unless ordered).Continued bubbling = pneumothorax not resolved yet, Constant vigorous bubbling = air leak in system Should see tidaling if not attached to suction >100cc/hr. of drainage = call doc Determine if working correctly by: Monitor output, pain, breath sounds, assess patient breathing, auscultate, ABG, pulse ox (SPO2), skin/mucous membrane coloring, and respiratory effort Chest tube pain is common- give pain meds >7/10 5.Review heart failure: right-sided (acute and chronic), left- sided (acute and chronic), pulmonary edema, cardiomyopathy and management of the patients; remember to review the hemodynamic changes (and values) associated with right and left sided failure RIGHT SIDED HF: (FLUID RETENTION): Corpulmonale, systemic edema, neck vein distention, weight gain, fluid retention, Risk: COPD, hypoxia (pulmonary HTN), causes pulmonary vasoconstriction.CVP = increased; PVR = increased; SVR = increased; wedge = increased; contractility = decreased medication: nitroglycerine to decrease venous return, fix preload LEFT SIDED HF: (RESPIRATORY) DYSPNEA ON EXERTION, back up in lungs, pink frothy sputum, decreased O2 stat, increase RR. CVP = increased; PVR = incre ased; SVR = increased; wedge = increased; contractility = decreased HEART FAILURE: Usually starts out with one ventricle.Nitroglycerine, aspirin, O2, pericardial thump, Lasix, ACE, + inotrope, Class 4, transplant, symptomatic. ACUTE HF: Dig, Lasix, ACE, ARBS, Betas, Calcium Channel, Nitro, and Aspirin, compensatory mechanism is ok. CHRONIC HF: both ventricles can fail (left to right), Dig, Lasix, ACE, BETA, ARBS (if cough), calcium channel blocker, Primacore, compensatory mechanism makes it worse. 2 CLASSIFICATIONS OF HF: 1. Systolic: problems pushing volume out problem with too much afterload: HTN. TX: decrease SVR with dig, Lasix (diuretics), ACE. 2.Diastolic: problem with filling and getting blood in (Hypertrophic cardio) less room for blood TX: Beta blockers to reduce contraction or calcium channel then ACE. If you give them DIG it will kill them (will increase heart working too hard). PULMONARY EDEMA: hallmark: pink frothy sputum, Left- sided heart failure. Decreased albumin, d ecreased oncotic pressure, increased hydrostatic pressure. Dilated: Left vent is dilated (stretched out of shape) decreasing the ejection fraction. Vent is overstretched from CHF or chronic hypertension.Diagnose with chest X-ray: heart is BIG. TX: Dig, Lasix, Ace. Arrhythmias will increase mortality rate HYPERTROPHIC: L vent hypertrophy decreases the ability of the chamber to relax, decrease contractility (athlete, hereditary. ) TX: BB, CCB Constricted/restricted: normal size heart with decreased cardiac muscle compliance. Scarred= fibrosis, radiation, infection (rheumatic fever) control of volume overload is AGGRESSIVE: Ace, Diuretic, Dobutamine, Nitroglycerin/Nitropresside, exercise restriction . Review patho and management of COPD, especially related to acute respiratory failure. COPD: obstructive, exhalation problem, air flows in but then becomes trapped, teach pursed lipped breathing to improve FRC. Clinical manifestations: increased lung expansion, normal to increased TLC, dec reased forces expiratory volume, increased functional residual capacity, decreased vital capacity, increased CO2, O2 sat-80-100, PaO2- 60 Best mask to use is vent mask, most precise O2 is delivered.Barrel chest- chronic hyperinflation of torso Corpulmonale, > expiratory time, wheezing or rhonchi, A fib from chronic overuse of right ventricle TX: beta agonist/beta stimulant=dilates airway (epinephrine, albuterol) Anticholinergic bronchodilators, corticosteroids, mucolytic=thin out secretions, Mucinex or SVN mucomist, pulmonary vasodilators not common, prostaglandin E2, supposed to dilate pulmonary vessels but BP can plummet too.Nitrous oxide can temporarily improve pulmonary HTN but doesn’t improve outcomes Respiratory Failure: ALOC- confusion, restless. Nasal flaring, increased HR, increased BP, increased RR, increased depth, PVCs, Pulmonary Embolism=blue very fast, otherwise cyanosis is a late sign 7. Review management of patients on ventilators, including process of weaning and recognition of weaning failure AC – assist control: doing all the breathing for the patient. It’s providing Tidal volume and oxygen.For your unstable patient NO pressure support needed SIMV – synchronized intermittent mandatory ventilation: For weaning: Makes it easier for patient to take their own spontaneous breath. Tidal volume off and O2 on. Pressure support adjunct PEEP – positive end expiratory pressure, Keeps alveoli open by use of positive pressure. Increases FRC – air left in after exhalation. ARDS patient. Little bit of positive pressure at the end of exhalation. Use with SIMV or AC. Keep between 5-10, and not over

Momaday (Indian History) essays

Momaday (Indian History) essays It is as hard to classify N. Scott Momadays The Way To The Rainy Mountain as history, as it is hard to classify Momaday as a historian. According to Marius there are four main assertions to consider before making a decision. The first assertion is that historians study sources that tell them about the past, and they write because they see something in these sources that needs to be explained. Momaday does not necessarily study the sources written down by scholars that tell him of the past. He is merely remembering oral stories told to him as a child. He is letting the outside world into the Kiowa history for our benefit not for him to study it. Also, Momaday writes these stories to preserve them so they may not be lost forever, they do not need to be explained. The second assertion is that all historical writing begins as an effort to answer questions. We find a puzzle and try to solve it. Momaday in no way is trying to answer any questions. There is no puzzle he is looking to solve. The stories explain themselves and leave no questions unanswered. The stories are just that, stories. The purpose of these stories is to have a written account of his culture and history, because oral history can be lost forever. The next assertion is that our knowledge of history is always in flux; historians are always in dialogue not only with the primary sources of events (written accounts) they write about but also with other historians who have studied these events. To write history is to be engaged in an eternal argument. The Kiowa people have certain traditions. One of them is the telling of their history and where they came from. These stories get told a million times over and to many generations. To all Kiowa people there is argument as to their beginning. Momaday knows that these are the stories of his people and that historians will say that the stories are just to explain the u ...

Project Management Take-Home & Interview Assignment

Project Management Take-Home & Interview - Assignment Example These individuals take part in the decision-making processes that may occur when the project is underway. To ensure a success for the project, the roles of ach of the members of this project organization need to be specified and each individual should stick to his are of jurisdiction. The project manager is the leader of the project organization. The manager has the responsibility of managing the resources that are available for the project. He or she is also responsible for ensuring that the project is executed according to the schedule. Communication is very important in the management of a project. ‘It is important that all members of the project team (including the client) be on the same page at the same time during every phase of the project’ (Goto, 2000, p.5). It should be noted that all the activities in a project are essential for the completion of the project. A close and effective communication mechanism will enable the project manager and the other members of the team to identify the areas that may cause delay in the completion time of the project. This problem can then be fixed in liaison with the client depending on its gravity. There is need for constant communication with the project sponsor/client. This can be achieved by issuing more than one reliable communication means like mobile phones, e-mail addresses. The client organization and the consulting firm both have their permanent contacts that should be exchanged during the execution of the project. Failures in projects can be caused by risks and uncertainties that may not be foretold. However, the risks can be minimized by observing certain criterion. In planning for the project, it is important to ensure that the activities involved in the tasks are identified and time estimates given accordingly. The project manager should ensure that proper

Assignment 3 Example | Topics and Well Written Essays - 750 words - 1

3 - Assignment Example The landscape is, therefore, irregular, comprising both hills and valleys; hence, resulting in short rivers. On the other hand, in passive continental margins, there is limited tectonic activity; the major processes that occur here are weathering and erosion. This results in level, flat landscapes along the beaches, characterized by long rivers and large debris of sediment. The oceanic ridge, which is a continuous submarine mountain range spanning 80000 kilometers, is elevated relative to the other areas of the ocean floor. The elevation is brought about by convection currents that rise from deep within the earth’s crust through a mantle in a line of weakness, in the form of magma. When it emerges on the earth’s crest, lava cools down and forms a new surface on the sea bed. Continuous eruption and cooling of lava leads to a build-up of materials, which in turn cause elevation at the point the activities take place. The result is a ridge, which is higher than other sections of the ocean floor. Mesosaurus was a reptile that lived in fresh water lakes thousands of years before the existence of dinosaurs. The fact that scientists found its remains, in Eastern South America and Western Africa only, suggests that the two continents could have existed as one land mass millions of years ago. Whereas some schools of thought could have it that the reptiles could have swum across the Atlantic Ocean, this could not happen since Mesosaurus could neither survive in the ocean waters because of their saltiness, nor swim across the ocean due to its expansive nature. These, together with the fact that the coastlines of the two continents fit like pieces of a jigsaw puzzle, enforces the theory that the two continents once existed as one expansive land mass. One of the main objections to Wegener’s Continental Drift Theory was his inability to explain the mechanism through which the continents drifted apart. He proposed two theories; a
