Airborne infectious disease

Airborne infectious diseaseTuberculosis (TB) is an airborne infectious disease which is caused by bacteria belonging to Mycobacterium terabyte complex1. There be approximately one third of the worlds population are give with terabyte where nine millions of new cases reported annually2. Although tuberculosis is essentially curable and preventable, it continues to cause millions of deaths every year2. When infected individual coughs, sneezes or spits, M. tuberculosis is propelled into the air and infected those who breathed in the bacteria that existed in droplets of saliva3. Primarily, tuberculosis impart chance on the lungs, known as pulmonary tuberculosis3. It will also affect other parts of torso, for instance lymph nodes, bones, brain and kidneys3. Once a person is infected with tuberculosis, in that respect are basically three possible ways may occur. Firstly, the repellent system plays a vital role and strong enough to kill the bacteria3. Secondly, immune system is not strong enough to difference of opinion off the bacteria just now is able to build a defensive barrier against the bacteria3. Individuals who are latently infected with M. tuberculosis show asymptomatic where these bacteria lie dormant in the lungs and able to reactivate aft(prenominal) years1. The disease is often reactivated in those who are immunocompromised or generally weakened. Lastly, the immune system fails to kill bacteria causing the bacteria to grow and spread towards other parts of body which is called active tuberculosis3. In the fight of tuberculosis, World Health Organisation (WHO) recommends universal Bacille Calmette-Gurin (BCG) vaccination in the countries with high TB burdens4. BCG vaccine contains weakened form of M. tuberculosiswhich will induce antibodies to fight against this type of bacteria. The efficacy of BCG vaccination can be ranging from 0% to 84%5. This may be due to the frequency of TB exposure and quality of vaccine used, leading to arguments on BC G vaccination efficacies4. One of the greatest arguments is that BCG vaccination causing positive reactions to tuberculin skin testing and hence interfere with the diagnosis of latent TB4. organism of evidences showing the rates of efficacy also depends on geographical location, age at vaccination and form of TB further complicate the situation. Currently, TB chemotherapy is do up of a cocktail of counterbalance-class honours degree-line drugs isoniazid (INH), rifampicin (RIF), pyrazinamide (PZA) and ethambutol (EMB) 6. If the treatment fails due to bacterial drug resistance, or patient unable to tolerate, certify-line drugs for instance para-aminosalicylate (PAS), fluoroquinolones, ethionamide and cycloserine are introduced6. These are considered as second line drugs generally either less pixilated with larger doses or more toxic with serious side effects6.Tuberculosis is presently treated in devil phases, namely initial phase and continuous phase7. In initial phase, the pati ent will be treated with concurrent use of four first line drugs, with the aim to eradicate or control bacteria population to replicate in rapid motion and also avoid the emergence of bacteria resistance7. The treatment choices available for initial treatment include isoniazid, rifampicin, pyrazinamide and ethambutol7. Streptomycin is used rarely but can be used in patients who infected with bacteria that are resistant to isoniazid before the therapy is commenced7. The duration for initial phase is 2 months whereas the continuous phase takes 4 months7. During the four months of continuous phase, patients are treated with isoniazid and rifampicin at same doses7. Most of the TB treatment is supervised where drug administration needs to be fully supervised by healthcare professions since drawn-out duration of treatment causing incompliance in patients7. These patients who are unlikely to be compliance will be given the drugs three times a workweek until the course is completed while patients who able to comply with the treatment will not be supervised7. Despite the chemotherapy treatment and BCG vaccine, TB remains as a substantive infectious disease due to increasing emergence of drug resistant TB and co-infection with Human Immunodeficiency Virus (human immunodeficiency virus) 6. Since the host defense in HIV patients is suppressed, they are more susceptible to TB infections. Moreover, drug- drug interactions between antiviral therapy and anti-TB also causing complications in treating co-infected patients6. Drug resistant TB has evolved mainly because of haywire treatment or incompliance in patients who stop taking their medications before the bacteria is being fully eradicated since the duration of treatment is lengthy which takes 6-9 months8, 9. The mechanism entangled includes chromosomal mutations in genes that responsible for drug targets encoding9. When there is a sequential accumulation of mutations, multi-drug resistant tuberculosis (MDR-TB) emerge s where the M. tuberculosis strains will resistant to two of the most usually used drugs, Isoniazid and Rifampicin9. Patients with MDR-TB are then relying on the second-line drug classes, fluoroquinolones and the three injectable elements namely amikacin, capreomycin, and kanamycin10, 11. The chances to cure would dramatically be reduced for patients who infected with extensively drug-resistant tuberculosis (XDR-TB), a situation where the isolated strains are resistant against any one of fluoroquinolones and at least one of three injectable drugs12.In coiffure to combat with the MDR-TB or XDR-TB and optimize the tuberculosis drug regimen, it is crucial to understand the mechanism of action of current using first-line drugs and how resistance is developed against these drugs. Isoniazid (INH) or isonicotinic acid hydrazide is observe in 1952, a germicidal agent which active against organism of the genus Mycobacterium, especially M. tuberculosis, M. bovis and M. kansassi6, 13. In vivo, INH has shown to be bactericidal in civilisation over the first 48 hours which become bacteriostatic by and by this particular time frame13. This indicates that INH is bacteriostatic for s commencement growing or resting bacilli but is bactericidal for rapidly dividing mycobacterium. The minimal tuberculostatic concentration is 0.025 to 0.05ug/ml14. INH is a prodrug that needs to be activated by catalaseperoxide hemoporotein, KatG before acts by inhibiting mycolic acid synthesis and cell fence disruption in susceptible mycobacterium14, 15. This inhibitory action is very specific since mycolic acids are unique to mycobacteria14. INH acts by inhibit enoyl acyl carrier protein (ACP) reductase, InhA, and a beta-ketoacyl-ACP synthase, KasA that are crucial in fatty acid synthesis system for mycolic acid16. Resistance to INH is believed due to mutations in gene encoding catalaseperoxidase katG or InhA or lacking KatG9, 15. Isoniazid is metabolised in the liver, mainly by acetylat ion and dehydrazination where s lower-ranking acetylator may experience higher concentration leads to say-so toxicity before excreted in the pee within 24 hours14.Rifampicin (RIF), discovered in 1963, is a lipophilic semisynthetic derivative of rifamycin antibiotic which is produced by the fermentation of a strain of Amycolatopsismediterranei6, 9, 17. RIF has bactericidal activities against a broad spectrum of microorganisms including gram-positive and gram-negative. RIF will inhibit the action of DNA-dependent RNA polymerase of mycobacteria that is encoded by rpoB through formation of a stable drug-enzyme complex9. This will suppress the induction chain formation in RNA synthesis and hence prohibit protein synthesis in M. tuberculosis9. Development of resistance to RIF is mostly due to mutation in 81 base pair region of rpoB gene thus facilitate a straightforward approach to detect MDR-TB since 85-90% RIF-resistant strains are also resistant to INH9. RIF produces bank note plas ma concentration of 7ug/mL in 2 to 4 hours after ingestion of 600mg18. It also distributed advantageously to most of the body tissues and fluids, including cerebrospinal fluid since it is lipophilic18. undermentioned absorption from the gastrointestinal tract, RIF is eliminated rapidly in the bile with fewer amounts excreted through urine18. Pyrazinamde (PZA) is discovered in 1954 and it produces excellent sterility effects against semidormant tubercle bacilli at pretty acidic pH6, 9. The antimicrobial activity of PZA is through interference with mycolic acid synthesis in M. tuberculosis by pyrazinoic acid, an active moiety of PZA9. Conversion of PZA to pyrazinoic acid is intercede by pyrazinamidase enzyme that is encoded by pncA gene in M. tuberculosis, thus indicating that these bacilli are sensitive to PZA9. Resistance against PZA evolved when mutation occur at pncA gene that is responsible for pyrazinamidase, hence affect the activity of this enzyme9. PZA is well absorbed fr om gastrointestinal tract and is widely distributed to most tissues and fluid too18. The oral administration of 500 mg PZA produces plasma concentrations of 9-12ug/ml after two hours and 7ug/ml after 8 hours18. PZA is metabolized in liver whereas the metabolites are excreted through renal glomerular filtration18. Ethambutol (EMB) is discovered in 1962, acts as bacteriostatic agent and is active against undergoing cell division6, 19. EMB primarily targets on impairment of cell paries polymerization by inhibits arabinosy transferase, a vital enzyme responsible for mycobacteria cell protect biosynthesis9, 19. Since arabinosy transferase enzyme is encoded by embC-embA-embB genes, resistance against EMB evolved is believed due to mutation of these genes9. EMB is currently used as one of the first-line treatment for tuberculosis mainly because of its synergistic effect with other front-line drugs and its low toxicity property19. There is roughly 75-80% of an oral dose of EMB is rapidly absorbed in gastrointestinal tract with absorption unaffected when administered with foods20. In addition, EMB is distributed widely to body tissues and fluid, including cerebrospinal fluid before being metabolized in the liver and excreted in urine20. Streptomycin (SM) is an aminoglycoside antibiotic, used as first line treatment for TB when it first discovered in 19441, 6. Streptomycin is isolated from the bacteria Streptomycesgriseus and its antimicrobial effects against M. tuberculosisis highly effective when use in combination with other first line agents21. However, SM is no longer considered as first line treatment as resistance against it has developed rapidly1. The optimum pH for SM is at pH8 where its bacteriostatic activity will reduce with increasingly acidic environment21. SM acts by binding tightly to A site of 16S ribosomal RNA fractional monetary unit, interferes with mRNA translation, causing faulty protein being produced1, 9. resistive emergence when the mutatio n occurs at gene rpsL and rrs that encoded for 16S and S12 ribosomal protein1, 9. Upon administration, SM is poorly absorbed from gastrointestinal tract and mostly administered parentally1. SM is mostly excreted in urine and patients with low renal profile might experience toxicity such as neurotoxic reactions1. When the first line treatment is no longer suitable for patients or patients develop multi-drug resistance TB, second line drugs will then be introduced in combating the TB. Second line drugs that are mostly used include Ethionamide (ETH), Cycloserine (CS), Para-Aminosalicylic caustic (PAS) and Fluoroquinolones (FQ). ETH has been in use since 1960s, is a structural analogue of INH and it targets at inhibition of mycolic acid biosynthesis in tubercle bacilli9, 22. INH however is lots more potent than ETH since the minimal inhibitory concentration for ETH is 0.5-5.0ug/mL22. Resistance evolved due to mutation at gene InhAand ethA which encode for oxygenase enzyme in activation of ETH 9. In vitro, CS has inhibitory effect on M. tuberculosis at 5-200ug/mL and there is no cross resistance occurred between CS and other drugs14. CS acts by interfereing the biosynthesis of bacterial cell wall14. CS is well absorbed in gastrointestinal tract and also widely distributed to body tissues and fluid including cerebrospinal fluid14. PAS was first introduced as first line drug but being replaced by Ethambutol in 1960s1. It acts bacteriostatically with possessing inhibitory effect at concentration less than 1mg/ml by interfere with folic acid metabolism in bacteria1. PAS is readily absorbed from gastrointestinal tract and distributed well throughout the body. Approximately 80% of the drugs will be excreted via kidney after being metabolized to acetylated form1. Moxifloxacin and Gatifloxacin are both been synthesized and evaluated as excellent bactericidal agents through inhibiting DNA gyrase, an ATP-dependent enzymes topoisomerase II which is responsible in bacteria DN A transcription9. DNA gyrase is consisted of two subunits that is arranged in a complex, is encoded by two different genes, gyrA and gyrB where mutations at gyrA will normally cause bacteria resistance to these new generation of flouroquinolones9. referable to the increasing incidence of multidrug resistance TB, it is highly desirable to develop new drugs that are not only potent and effective against current resistant strains of M. tuberculosis but also possess shorter treatment duration since most of the incompliance of patients is brought up by lengthy TB treatment. Most of the mechanisms of action of current treatments are involved in interfering the bacterial DNA synthesis, protein and mycolic cell wall biosynthesis. The enzymes that participate in these pathways could also be the target of newly designed drugs such as TMC207, one of the new drugs which are currently under investigations and clinical trials.TMC207 is a member of diarylquinoline class of compound which target at adenosine triphosphate (ATP) synthase by binding to subunit C of the synthase, blocking the energy pathway of mycobacteria23, 24. In vitro, TMC207 not only possesses ability to inhibit both drug sensitive and resistant M. tuberculosis isolates, but also able to sterilize the patient through killing the dormant bacilli bactericidally23. TMC207 showed a minimum inhibitory concentration of 0.03ug/mL against M. tuberculosis, suggesting a more potent agent compared to current first- line treatments such as isoniazid and rifampicin24. Apart from that, its synergistic effect with pyrazinamide could promise as effective drug combination for sterilizing the patients against TB23. A phase I clinical trials which involved short terms administration of TMC207 in healthy individuals showing no adverse effects and the subjects are well tolerated with it24. However, it is essential to investigate the selectivity of TMC207 against mammalian ATP synthase with longer periods to ensure the patients s afety when administered with TMC207. Thiacetazone (TAC) is widely used as second line anti-TB agent against multiresistant tuberculosis at present25. TAC acts by interferes the biosynthesis pathway of mycolic acid in tubercle bacilli25. The fact that M. tuberculosis has been difficult to eradicate and remains persistent is due to its cell wall that composed of mycolic acid which is resistant against chemical injury, dehydration and also has low permeability to antibiotics25. Mycolic acid contains cyclopropane rings that is activated through cyclopropane mycolic acid synthase (CMASs), has a significant contribution to tuberculosis25. By inhibiting the cyclopropanation, the cell wall biosynthesis will then be interrupted, introducing the bactericidal effects25. The aim of this research is to synthesis and evaluates the analogues of Thiacetazone which might be potential anti tuberculosis agents. The analogues will be tested against different strains of mycobacteriain lab. The target a ctions of these analogues will also be identified based on the structure of the analogues. The to a higher place analogue is synthesized when a benzylaldehyde reacts with a primary amine. This is a condensation process and an imine is produced. The changes at position R1 to R3 with different electron withdrawing groups are first planned to be evaluated. However, the plan is prohibited since the corresponding structures are either unavailable or too expensive that falling outside the budget. After revised on the preliminary analogues that were discovered and their respective MIC values obtained from lab, the structures of new analogues that are going to be evaluated are finally sorted out. The R1 to R3 positions would be replaced by either a -chloro or a -methoxy with R8 position would either be an amine, a methyl or a benzene ring. A chloro is used at position R1 to R3 since it is electron withdrawing, volumed and lipophilic molecule whereas the methoxy group is electron donating , small and quite lipophilic. For R8 position, an amine is selected because it is electron withdrawing and small. A methyl is also selected since it is quite lipophilic, small and electron donating. On the other hand, benzene ring which is highly lipophilic, neither electron donating nor withdrawing group might have a different effect on the analogue synthesized.

The results obtained are slightly incorrect due to any errors as part of the experiment. My calculations were all shown for trial one which whereas follows. In relation to the graph, the line does not pass through the origin as there were uncertainties. The line therefrom starts a few cm from the origin on the y axis. The slope in the graph indicates the spring constant. It can be seen that the spring constant entertain in the graph does not match my result fo r trial no.1 as I have taken the spring constant value in N/cm. If I take the values in N/m and average all the values of the spring constant from my calculations I will end with a result equal to the gradient or slope of the graph that is 0.227. The units taken for every other value is standard and therefore is correct. My results are reliable as they do result in the Force being proportional to the Extension. I feel that my data is reliable and the graph does show that the extension of the spring directly proportional to the force that is applied to it. We excessively found that the spring constant and the elastic potential energy increases due to the extension of the spring being proportional to the force.EvaluationI have found that the experiment did have many errors which could have been improved. There were both systematic and random errors involved in the experiment. The meter ruler (uncertainty of 0.05cm) and the digital balance (uncertainty of 0.1g) had uncertaintys which could have altered the accuracy of the results. The experiment also had a parallax error due to the carelessness of me not observing the pointer and the length in the straight path. My equipment was not very undefiled as I was given a meter ruler and not an attached ruler. This could have made it very inaccurate as the ruler was leaning over a contend. I could only take one reading per mass, as time management was an issue, which is not reliable as taking more than two readings and averaging the answer will give a more accurate result. The next time I perform this experiment, I will need to make sure that I have at least three readings per mass and should take the average of the three readings to minimize the errors. I should also make sure that the meter ruler is not leaning on a wall and that it is held on by a clamp or that I have the ruler stuck behind the clamp stand. While repeating the experiment one should also put a pointer on the hook to avoid parallax error and get the measurements even more accurate.Wasif Haque

Inequalities in Health Care Essay

Inequalities in Health Care EssayThe conditions in which sight buy the farm have a profound influence on their health. Difference in health mingled with individuals and population groups exist in all societies. For example younger age population generally have good health compared to old population. This kind of health inequality stacknot be concluded as health inequality because it is natural. So the question is that when the difference in health becomes inequality? fit in to Graham the difference in health between population groups becomes inequality when it is linked to the inequalities in their position in society (2007 99). World Health agreement appointed Committee for the Social Determinates of Health (CSDH) also hold confusable view as not all health inequalities are unjust or inequitable. If good health were simply unattainable, this would be unfortunate but not unjust. Where inequalities in health are avoidable, yet are not avoided, they are inequitable (2008 14). So the differences in health between groups having unequal position in society become an ethical issue.Evidences of the existence of health inequality are abundant. If we admit life prediction as an indicator, resent evidences show that there exist significant differences in health between world regions (see Appendix 1). Life expectancy at birth varies between 78.8 years in the higher income OECD countries to 46.1 years in paladin Saharan Africa. Life expectancy improvement over the outcome 1970-75 to 2000-05 shows that life expectancy has increased all regions in the world except the constellationer Soviet Union countries. It can observe that the increase was not similar in all regions. Life expectancy increased almost 10 years in developing regions over that period while in Sub Saharan Africa the increase was only about 1 year.Inequalities in health not only exist between countries or regions. Even within the republic health inequalities exist. A study in the Scottish city o f Glasgow found that life expectancy of men in one of the most deprived battlefield was 54 years while that most affluent area was 82 years (Hanlon, Walsh Whyte 2006, cited in CSDH 2008). Men with the lowest life expectancy in the joined States of America in 1997 2001 had dispirit life expectancy than that of Pakistan average in 1995 2000 (CSDH 2008).Studies show that socio- frugal status affects health. Differences in life expectancy at birth by amicable course of action in England and Wales from 1972 to 2005 shows that it has improved for all classes during the period 1972 -2005 (both males and females). Surprisingly the same difference in life expectancy existed in 1972 between social class was found existed still in 2005 (see Appendix 2 and 3). Even in health behaviour difference exist between socio-economic classes. Percentage males and females forage in England and Wales during 2001-07 period shows that smoking rate is comparatively higher among lower occupational classe s (see Appendix 4). Whitehall II study which investigates the health of British civil servants between the age 20 and 64 found that mortality rate is high among low occupational classes (see Appendix 5).How material conditions affect health? The Black sketch published in 1980 by the expert committee into health inequality chaired by Sir Douglas Black was the first attempt to examine the relationship between economic inequality and health inequality. The main responsibilities of the committee were to bring together available information about the difference is health status among the social classes, examine the lend factors, and to analyse the collected information for casual relationships. The committee found that there was strong relation between social class and mortality-morbidity rates. It also found that bulk in lower class experience worse health and working class population underutilise NHS (Morall, 2001).The committee examined four possible renderings for the inequality. The artefact explanation suggests that the class inequality in health do not really exist. They only appear to exist because of the way class is constructed. The social selection explanation argues that mass who experience bad health tend to find difficult to get good job. There for they either move into or remain in lower class occupations. This means, people are in lower social class because of their poor health, rather than their class causing poor health. The behavioural/ ethnic explanation suggests that ill-health is due to not following a healthy life style. Lower class people are unhealthy because they smoke and drink too much, rust wrong kind of food and do not exercise. Finally the structural/material explanation view the material situation in which people live is the most important factor that determine health (Kirby, 2000).Based on the Ottawa Charter for Health Promotion number of models of the determinants of health has been developed. The model by Dahlgren and Whitehe ad (1991) is particularly important. This model identified that individual characteristics of age, sex and genetic makeup are core determinant of health. Other influences are represented by concentric layers each of which interfaces with the other factors. They suggest that the inner circle represented by the fixed characteristics of the individual cannot be modified but outer circles can be influenced by behavioural or other life changes (see Appendix 6).There are many theories that try to explain health inequality. Behavioural and cultural explanations suggest that individual behavioural choices are responsible for health outcome. The lower the income status, the person is more likely to engage in less health promoting form of behaviour. It is also found that those with more years of schooling, and with more qualification, are found to have healthier diets, to smoke less and do more exercise (Bartley 2004).The psycho-social model argues that the health difference between people in more and less advantaged social positions cannot be explained purely by material factors (Marmot 1989). Psycho-social model focus on how feeling that arises because of inequality, domination, or subordination may directly affect biological process by altering body chemistry. This model argues that availability of social support, falsify and autonomy at work, the balance between home and work, the balance between efforts and rewards etc. can affect health (Bartley 2004).The materialist framework sees the objective living conditions people living in explain relation between poverty and health. Material condition of life associated with poverty lead to greater likelihood of physical problems, developmental problems, educational problems and social problems (Blane et al. 1998). Neo-materialist model explains the relationship between population health and income inequality. It looks beyond individual level and gives more attention to whole societies and how they differ. It is argued th at absolute income is not the determinant rather its distribution is the matter (Wilkinson 1996 Wilkinson and Pickett 2009).Basic premise of life course approach is that persons past social experiences affect the physiology and pathology of their body. So this model argues that health in later adult life may be a result of complex combinations of circumstances taking place over time and the additive effects of circumstances can affect the health negatively in future (Davy Smith et al. 2002). The major purpose of the life course researchers is to see whether the difference in health between people in different groups is due to past adverse life circumstances (Bartley 2004)

Essay --

When should the Fed begin its exit from expansionary monetary policy? Or is this even the wrong question and should we instead be discussing and expansionary policy that can be conducted by the Fed?As Janet Yellen stated clearly in her recent testimony before the Senate Banking Committee, now is not the date for the Fed to begin its exit from expansionary monetary policy. Until inflation comes closer to the Fed target of 2 percent or the unemployment rate begins to steadily decline, the Fed should in fact be looking to further expansionary policy to give the economy all the help it can get. The current state of the U.S. economy in monetary value of unemployment, inflation and growth, allow this unique situation to be brought into light. The unemployment rate is in about three percentage points higher than it was seven years ago, before the send-off of the economic downturn. The employment-to-population ratio is about five percentage points lower, and it has not succeeded in recov ering much since the trough of the recession. Furthermore, in a dataset compiled since 1948 the average unemployed soulfulness has been looking for work before the crisis was 22 weeks, in the aftermath of the recession of 1981-1982 (Mankiw). In the most recent recession, however, the average reached about 41 weeks and still stands at more than 36 weeks an unprecedented number of long-term unemployment. The Fed, breaking from its historic emphasis on subduing inflation, has used inflation as a tool to cultivate the financial crisis and keep prices rising about 2 percent a year. Rising prices encourage consumption, increases profits, increases borrowing and investment spending. Yet despite this goal, inflation lift at an annual pace of 1.2 percent in August, just... ...useholds and businesses (consumption and investment) increases purchase of real estate, which increases the price of homes. Though increased housing prices and increased employment are both effects of expansionary monetary policy, higher housing prices do not necessarily benefit employment. Or in other words, higher housing prices do not directly benefit employment but are sometimes transfer to be a signal that employment is on the rise.On Washs point, he says that in some sense the Feds economic models have been basically wrong for about 4 or 5 years. By this he means that the models did not anticipate the crisis, or were imply incorrect during the past 4 or 5 years of the recession. The models do not take into account that policy response might be different, rather, they take into account a pattern of snapping-back to where they once were at a point in history.

From the many inventions that emerged from the American Civil War, the Ironclad, designed by Captain John Ericsson and Robert L. Stevens, has impacted the world by advancing naval warf ar technology. It gave America more influence in europium and put America ahead of Europe in naval matters. The impact and influence changed naval warfares constantly by forcing wooden ships to become obsolete. The Ironclad was among the first technological and modern tools of war. Its impact on technology in navies can still be seen like a shot in the designs and the construction of naval ships.(Mac Bride,1) It has impacted technology in the way ships are built. Because of the brassbounds the ships that are used in wars today are much safer. They are stronger and easier to maneuver. The first ironclad to ironclad battle between the Merrimac and the Monitor was long and drawn out. Although neither one emerged victorious, the world began to see what a major melioration in warfare these ironclads we re. A reporter from the Norfolk Day wrote This work will create a revolution in naval warfare. Americas improvement has impacted naval history in a way that no other invention ever has (Davis,135) Many times in unify States history the major nations of the world, such as England, France and Germany, have ignored the United States in political matters but this invention and the ironclad to ironclad battle changed a large percentage of their attitudes toward the United States. It made America become feared and respected by large European nations and all the major nations looked at this invention with pure respect and awe. (Love,29) The invention of the ironclad has helped to push America higher on the ladder to becoming a major world power and to be included in major decisions of the world. The ironclads caused a long range of reaction in navies and gave America a push for the influence they wanted in Europe. Many say that the invention of the ironclad is rather possibly one of the chief reasons for the continued existence of the United States. (Mac Bride,43) In the past people have often thought of naval ships as just tools of war. Many never considered that a ship could be useful in improving foreign policy and in pushing for American influence, but when Europe heard about this invention they began to realize that America had an adequate navy and the largest and finest destroyers in the world.
