Analysis of Small Molecule Analogues of the helminth immunomodulator Dissertation

Analysis of Small Molecule Analogues of the helminth immunomodulator ES-62 for inhibitory effects on mast cell function - Dissertation Example However, particularly in countries where helminth infections are endemic, these diseases remain comparatively rare. There is increasing evidence indicating that helminth infections and inflammatory diseases share an inverse relationship. Therefore, helminths have been the focus of recent studies. William Harnett and his team discovered an immunomodulator ES-62 secreted by a parasitic worm that is known to hold a strong cure for allergic and autoimmune diseases, such as asthma and arthritis. However, there are some practical implications associated with a high level of ES-62 production that renders it unable to be used as a drug. Hence, it is hypothesized that synthesis of ES-62 derived SMAs based around its Phosphorylcholine moiety can mimic the effect of the parent molecule and have a potential to be used as a drug for clinical trials. This project investigated the effect of SMAs on mast cells by implementing the Rat Basophilic leukaemia degranulation assay in which SMA 53 and SMA S 3 were found to inhibit Fc?RI-mediated mast cell proliferation. Also, a substantial decrease was observed in IL-6 and TNF-? cytokines production. The data presented here established that some SMAs certainly have potential to induce the same effects as ES-62 and thus to be used as a therapeutic agent. Introduction Tropical parasites disease affects millions of people throughout the developing world. These infectious diseases cause long term suffering which leads to significant economical damage. For this reason, The World Health Organization has committed to fight and extirpate many of the most costly diseases (W.H.O, 1990). 1.1 Filarial nematode Filarial nematodes are thread like worms that infect up to 1/3 of the human population and cause diseases such as river blindness and elephantiasis (Harnett and Harnett, 2010). People infected by these worms appear to be comparatively asymptomatic, even when they are carrying a noticeable parasite burden (Harnett et al., 2010). According to a number of reviews, infected individuals can harbour more than one type of parasite, but major tissue habitants of humans are the filarial nematodes which usually live in the lymphatic system or the subcutaneous tissue (Harnett and Harnett, 2008a; Schmidt and Roberts, 1989). Infection with such worms is transmitted to humans by blood-sucking insects that act as an intermediate host; they do this by transferring L3 stage larvae to humans (Harnett and Harnett, 2008a). Fig. 1: This diagram illustrates the life cycle of filarial nematode and how the worm is transmitted into the human body [6]. The duration of these infections are very long as an individual worm can survive for up to 10 years, which indicates the importance of this parasitic worm in the medical field (Harnett et al., 2010; Harnett and Harnett, 2008a; W.H.O, 2000). Over the past decade it has been hypothesised that filarial nematodes may protect against autoimmune and allergic inflammations. For this reason, parasitic ne matodes have been involved in many recent studies and there is now enough evidence to prove that nematode-derived immunomodulators play a fundamental role in preventing inflammatory diseases in the human populat

Cheap Labor and Outsourcing Research Paper Example | Topics and Well Written Essays - 3000 words

Cheap Labor and Outsourcing - Research Paper Example y workers with robots.† (Musil, 2012) But for the cheap labor available in the thickly populated countries like China, India and Indonesia there is no other justification for shifting or creating new facilities in these countries by the American companies. In fact, the companies do make several compromises in other areas to exploit the cheap labor. Do we have plans to shift the production facilities back to America, if labor could be replaced with robots? The indiscriminate outsourcing drive is neither in the interest of the host countries nor in the interest of the USA in the long run. This paper seeks to analyze the causes for outsourcing either within the country or to foreign countries, its impact on the business and economy of the USA and the host countries. It is not the question of what is good to American economy. The issue has several dimensions. Is corporate social responsibility of the multinational companies engaged in outsourcing spree limited to only the USA? Are they not responsible for human rights issues involved in the operations of the suppliers? Disturbance of the existing equilibrium in the employment market either locally or internationally creates serious imbalances in the economic system in the long run and result into a situation of ‘catching the tail of a tiger’, meaning neither you can afford to leave the tail nor holding it for long! â€Å"Outsourcing is generally recognized as a strategy for producing cost saving, however, by simply following a traditional cost-focused approach, companies may be missing opportunities to gain further competitive advantage† (Deloitte, 2008). The following points need to be carefully considered in respect of cheap labor in view of its impact in general on the economy. 3. The market is saturated locally and establishment of production facilities in a third country could meet the local demand in such country and this unit could act as a hub for export of such products to other countries. In

International Refugee Law Essay Example | Topics and Well Written Essays - 4000 words

International Refugee Law - Essay Example Many of these states have been reluctant to offer asylum due to their own political and economic considerations. However, these asylum seekers have often displayed vulnerable qualities in terms of physical, psychological, as well as political support. For which reason, international governing bodies and host states have often ended up granting asylum to these refugees. However, recently, issues on the impact that these refugees have had on host states have been evaluated. Their economic impact has been a major consideration because these refugees have been considered as a significant drain to the resources of host states. The issue of their vulnerability has also been raised. In a decision by the European Court of Human Rights, specifically, in the case of M.S.S v Belgium, the court speaks of the applicant as a member of a ‘vulnerable group’. The case deals with the expulsion of an Afghan asylum-seeker to Greece by Belgium in accordance with the EU Dublin Regulation. The Court issued a standard-setting landmark judgement for the protection of asylum-seekers and it also held that asylum-seekers were a â€Å"particularly underprivileged and vulnerable population group in need of special protection†... He declared that they are not a group ‘historically subject to prejudice with lasting consequences, resulting in their social exclusion†2. This paper aims to critically discuss the judgement delivered in M.S.S v Belgium and Greece. Moreover, it will examine the current position of asylum-seekers who seek ‘international protection’ and the applicability of the legal framework under the 1951 Convention or under the International Human Rights. This paper will also attempt to evaluate the treatment of asylum-seekers in Europe, more specifically, in Greece. It shall also draw some comparisons with the recommended treatment as implemented by the Common European Asylum System. Finally, this paper shall also discuss the concept of vulnerability. This paper is being carried out in order to establish an improved understanding of the refugee laws, including the individuals who may or may not be considered refugees. It is also being carried out in order to assist legal a nalysts in making better judgments on the status of refugees. Background The ‘right to seek and to enjoy in other countries asylum from persecution’ is indeed a key provision in the Universal Declaration of Human Rights3. However, sometimes this right is not fully observed in parts of Europe today. Instead, asylum-seekers are met with hardship and suspicion and too often are treated inhumanely; some are even placed under detention. Asylum-seekers entering Europe have well founded fears of persecution. Most of their fears stem from their ethnicity, religion, nationality, political opinion, or membership in a particular social group; all of these qualities are very much different or opposed

Networks Systems & Technologies Essay Example | Topics and Well Written Essays - 3000 words

Networks Systems & Technologies - Essay Example The firm also has a traveling sales force which needs to connect to the office network to access the sales applications and other administrative applications. The network users include managers, designers, sales, finance staff and secretaries. From the perspective of IT users and network spread, this can be called as a medium scale company network. The overall IT strategy would be simple and would include the following elements for us to consider – The company network would follow a two-layered architecture (Figure 2) with the head office & factory in the top layer and other 3 offices in the second layer connected to the network backbone. All offices would be connected to each other through a Wide Area Network (WAN) (Figure 1). Users in the individual offices would be connected to the network through a Local Area Network (LAN) forming a â€Å"Star Network† (Figure 3) going into the Ethernet Hub. The Ethernet Hub would be connected to the router. The other offices would be connected via routers to the network backbone and supported remotely from the head office. This type of architecture is chosen because majority of users are in the head office and factory. For the company wide access to various applications and systems, an Active Directory Server system will need to be used. An Active Directory server will be installed at every location and will have to be identified as a Global Service Catalog (containing all user information), DHCP, DNS Server and Domain Controller. This will enable all offices to have network connectivity even when the WAN network lines to other offices are down. The storage of servers and cables as well as the individual speeds are also part of the overall network design but slightly technical in nature. The types of servers needed will be determined by the applications and other infrastructure management tools which will be used within the company. A category 6 data cable will be used to

Correlation of Crime and Victimization through Race and Ethnicity Research Proposal

Correlation of Crime and Victimization through Race and Ethnicity - Research Proposal Example In turn, a higher number of them have been victimized for the wrong reasons. The purpose of this study is to critically examine the disparity in the rate of victimization among the different races and ethnic communities in the U.S. The study is motivated by the high reports on victimization among the minority groups when compared to the Whites. Previously conducted research indicates that that the rate of crime and victimization among Blacks and Hispanics is higher than that among the Whites. It thus examines the underlying causes of deviant behaviors among the minority groups and what can be done to solve them and reduce the rate of victimization among the members of the minority groups. The quantitative method of data collection will be used in this study to compare the number of Blacks and Hispanics who are victimized against whites. It will be facilitated through the use of questionnaires on a sample of the population within the community and interviews for some of the convicted inmates. The random sampling method will be used to ascertain that the lifestyle exhibited by members of the minority groups within the United States is as a result of the unfavorable conditions that they are exposed to. These result in higher rates of crime and hence victimization, which results from an injury stereotype. In this case, the government must ensure equity and even distribution of resources among these groups to make them more independent, reduce their rate of crime and the ultimate victimization from individuals from the majority groups. In the recent past higher rates of victimization have been reported in the United States, especially among the Blacks and Hispanics who are considered to come from the minority group. This practice is associated with the stereotype that Blacks and Hispanics are criminals and hence should be made victims of their actions. In this sense, research and other records

Project 2 plan - Essay Example The second form is filled in by the investigating officer and comprises of stating the corrective action taken and the medical treatment administered. Conducting the investigation follows five phases; preparing for the investigation where the report of the accident is submitted, gathering evidence and information which can be executed by using digital photographs to extract evidence like camera matching, photogrammetry and rectification. It can also be done by interviewing witnesses for example by using the indirect conversational approach where the witness talks freely about the incident or through questioning the witness based upon his responses. The third phase is analyzing the data which attempts to understand the accident based on the available data collected. Various techniques are used like fault tree, failure modes and effects analysis, cause-consequence analysis and simulation. The fourth phase is discussion of the analysis and conclusion which involves documentation of the accident based on the understanding from the available data. The last phase is recommendations whereby specific advice is given on how to evade reoccu rrence of the accident based upon the investigation

Global and Domestic Distribution Essay Example | Topics and Well Written Essays - 1500 words

Global and Domestic Distribution - Essay Example Comparison of Domestic and Global Market. There are unique similarities and differences between domestic and global markets. While the similarities or potentialities are the raison d'etre for a planned expansion into global domain, the differences lead to challenges to be overcome while entering into an unknown foreign domain. Some of the difficulties which are sure to be overcome in a multi-national market distribution are appended in succeeding paragraphs. National Policies. A main hindrance in global distribution is often the national policies which in many developing countries discourage foreign players and support domestic ones. Further, changes in successive democratic governments can lead to frequently changing priorities/policies, unreasonable tax structure against foreign players thereby making penetration and distribution difficult. There have been many instances where huge investments have been made by certain global players in anticipation of growth in a particular field and with a change in the government, the whole process received a setback to an extent that the global player had to actually wind up and leave. Further, pioneers and domestic players also make all possible moves to deter entry by being on the right side of governmental public policies (First-mover advantages: Retrospective and Link with the Resource-based View MB Lieberman, DB Montgomery - Strategic Management Journal, 1998) Individualised Goods. While distributing a product in own country, the marketing manager is aware of prevailing situation, needs, growth pattern and other variables persisting in the market as well as the customer. This allows him to market the product to meet specific individual needs of the customer to a large extent. Any product meeting specific requirements of a customer will lead to better customer satisfaction, reputation and thereby automatic favourable advertisement of the product. However, in case of a foreign market, this adaptability is not available. The conditions prevailing in each and every country are different and products need to be manufactured in a country specific manner to suit requirements of customers as well as infrastructure, likely development pattern and economy of that country. A good research before huge investments are made will ensure requisite success when marketing a product in a new country. Getting the product or service to the customer. Buyer behaviour and characteristics directly affect overall objectives of a business. This aspect is critical to successful distribution in a global market. If the product needs to be made available to a large section of population of developing countries living in non-urban areas with limited resources, the task becomes even more difficult due to limited communication networks, distribution channels, lower advertising potential due to limited reach of media and lack of awareness of people about new products from a different country. Further, reaching out to individual customers and assuring him of product's worth is a near impossible task in countries where people have a very
