Drosophila Parkinson's disease model for Investigating Sleep Disorder Thesis

Drosophila Parkinson's disease model for Investigating Sleep Disorder of PD - Thesis Example Introduction Parkinson’s disease (PD) is an advancing and persisting neurodegenerative disorder that influences the control of the central nervous system (CNS) on the voluntary movement. It was first reported by James Parkinson in 1817, as â€Å"An Essay on the Shaking Palsy† (Parkinson, 2002). Much research has been carried out in two centuries towards understanding Parkinson’s disease but no definite cure could be attained so far. PD has emerged as the second most prevalent neurodegenerative disease after Alzheimer’s disease (AD). Diagnosis of Parkinson’s disease is difficult in early stages of the disease. Estimates reveal that only 75% of the clinically diagnosed cases are confirmed at autopsy (Gelb, 1999). Although the disease is non fatal but the linked complications culminate into life threatening consequences especially in the later stages of the disease (Morgante, 2000). The neuropathological studies disclose characteristics of PD and its c onnection with neuronal degeneration in substantia nigra pars compacta (SNpc), loss of dopaminergic neuron results in imbalance between dopamine and acetylcholine. As less amount of dopamine is secreted, there is overtone of cholinergic activity in basal ganglia, responsible for various clinical features of Parkinson’s disease. ... Lewy bodies are associated with neurological conditions, they enclose protein components of the ubiquitin proteosome system (UPS), hsp, neurofilaments, ?-synuclein and synphilin-1 (Olanow, 2004). Cardinal features of Parkinson’s disease is associated with motor symptoms encompassing resting tremor, rigidity, bradykinesia/ akinesia, shakiness in posture, gait and posture disturbances may be common including shuffling of the feet, decreased arm swing and stooped forward- flexed posture, pin rolling movements of thumb, drooling of saliva from mouth, expression less face or masked face, micrographia, impaired agility (Nussbaum, 1997). The non motor symptoms occur due to loss of non-dopaminergic pathway resulting in the distress in the patient and hence impairing life (Hely, 2005). Mood alteration is common in PDs, including depression (Lieberman, 2006), anxiety, cognitive disturbance, impaired attention, prioritizing, interpreting social cues, and subjective awareness, dementia, h allucination, delusion, short term memory loss, enhanced sexual activity and psychosis (Frank, 2005; Levin, 2005). Sleep disturbances, disproportionate daytime sleepiness with nighttime sleeplessness, distressed REM sleep (Freedom, 2007). Disturbed visual sensations, spatial analysis and color differentiation, PD cases are unaware of their body position (Adler, 2005). Nocturia, orthostatic hypotension, distorted weight (Martignoni, 1995). Risk Factors for Parkinson’s disease encompass advancing age, environmental predisposition, and genetic factors in the select genes. The onset of Parkinson occurs in the individual above 50 years. The cause of PD is idiopathic and genetic

Medical Career - Essay Example Significantly, the career of a medical physician offers me with ample opportunities and challenges to make me worthwhile to the humanity as it provides room for service, action, respect, security, excitement, mobility, and flexibility both in my career as well as personal life. Medicine is one of the very few effective career choices which fulfils these features of a rewarding career and offers better opportunities for service. Above all, it allows the leeway to grow in the area of Human biology which is one of my important interest-areas. The wider scope of this noble profession is an important factor affecting my choice of medicine as a career. "Most doctors' professional lives are filled with caring for people and continuously learning more about the human body. Every day in communities around the country, doctors work in neighbourhood clinics, hospitals, offices, even homeless shelters and schools to care for people in need. But physicians also do many other things People with me dical skills are in demand everywhere." (Exploring a Medical Career). In other words, a doctor's career is marked by a wider variety of opportunities, as compared to any other profession and there are physician researchers, academic physicians, and practitioners of various other spheres of medicine. Whereas the physician researchers are engaged in efforts to develop exciting new treatments for cancer, genetic disorders, and infectious diseases such as AIDS, the academic physicians share their skills and wisdom by teaching medical students and residents and others who work with health maintenance organizations, pharmaceutical companies, medical device manufacturers, health insurance companies, or in corporations directing health and safety programs. This wider opportunity in the medical career has been one of the reasons for my choice of this career. Significantly relevant to my choice is also the fact that medical career has several personal, intellectual, and financial rewards that attract me toward this career. It is essential here to make clear that the career development opportunity promised by medicine has great implications in my life as I always have given importance to human biology and wished to have a career growth in this stream. Human biology has been a great fascination for my career dreams and researches related to genetic variation, biological variation, degenerative diseases, infectious diseases, human growth development, and bio-demography etc have great scope in my academic interests. Of all these, biodiversity and genetic diversity have attracted me very much and several topics of personal reading comprised topics related to genetic diversity including genetic characteristics, population genetics, gene diversity, heterozygosity etc. I have been very much interested in the developments and inventions in the medical field of genetics and the application of genetics to human biology. Every time I read about some achievements and inventions in the field of genetics, I was fasci nated towards the capturing capacity of medicine. The understanding of all these factors along with determination for further studies and researches in these areas has been important factors determining my choice to pursue medicine. Primarily, it is the scope of medicine for growth and development in such vital areas of human knowledge, and the opportunity for building up a bright career in the best interest of

Benefits of the Ctrip Idea in the Future Life Case Study - 35

Benefits of the Ctrip Idea in the Future Life - Case Study Example Decision making will be easier for the traveling agencies due to the classifications of travelers (Mohinder, 2009). Â  This classification will be beneficial to the agencies in that they will be able to make decisions based on the ability of their clients and consequently treat a client fairly and thus increasing their customer base (David & Nancy, 2012). Â  This exhibit according to the case idea demonstrates the customer base beginning from 2007 when a new CEO is hired. Considering the vertical axis as the customer base in hundreds of thousands and the horizontal axis as the years moving forward, it illustrates that in the year 2007 the customer base was at 600,000. The figure increases to 800,000 customers in 2011 resulting from the acquisition of 16 percent by Tencent Company. This figure is predicted to rise in 2017 due to the recommendations made and the figure is projected to be at one million customers. This means the customer base in the projected future life will increase accordingly (Mohinder, 2009). Â  Considering exhibit 5, the case idea recommends that the increase in the customer base through the methods stated earlier will lead to increase in the profits due to increase in the travel activities above.

The Man That Corrupted Hadleyburg by Mark Twain Research Paper - 1

The Man That Corrupted Hadleyburg by Mark Twain - Research Paper Example Following this, the stranger decides to teach the entire region of Hadleyburg a lesson by turning them into corrupt citizens. He wants to make them aware of the ‘actual realities’ of life by making them turn to look at the kind of temptations and corruption that life actually contains. The stranger happens to have an entire plan of action in order to go about this process as well. This story has been written by the author as a pun on today’s world and different kind of people living in society. Living in an ideal world or a Utopian land is a concept not really known to mankind. Twain has tried to depict a very ‘clean’ society with citizens free from any bribery and wrongdoing. However, he also put in the character that tries to destroy this kind of perfect imagery and create havoc within the town. Through the eyes of this main protagonist Twain tries to tell his readers how it is impossible to live in a picture perfect world. According to the author, society is made up of all kinds of people, the bad and the good. This story however, gives an image of the good people that a society should ideally contain. Through this, Mark has tried his level best to make people understand that one cannot really live in such a place; and that such a society is not really something that would exist in today’s world. â€Å"It is an honest town once more, and the man will have to rise early that catches it napping again.† (Twain, Mark) The word ‘Utopian’ comes exactly from the meaning of this book on a different level. It is used to describe a situation, preferably a place or a region, where everything is perfect; where the people are living together in harmony, not fighting and are happy with everything that they have to offer to the people around them. However, this is not the case in real life because in reality, different kinds of people exist in the world. They each have their own views about living and surviving in the

Post Washington Consensus Consensus Essay Example | Topics and Well Written Essays - 1500 words

Post Washington Consensus Consensus - Essay Example primary health care, primary education, and infrastructure ;tax reform (to lower marginal rates and broaden the tax base);Interest rate liberalization ;a competitive exchange rate ;trade liberalization ;liberalization of inflows of foreign direct investment ;privatization ;deregulation (to abolish barriers to entry and exit) and secure property rights. This privatization agenda in pursuit of globalization has come under criticism as (1) says," Some of the most vociferous of today's critics of what they call the Washington Consensus, most prominently Joe Stiglitz... do not object so much to the agenda laid out above as to the neoliberalism that they interpret the term as implying. I of course never intended my term to imply policies like capital account liberalization...monetarism, supply-side economics, or a minimal state (getting the state out of welfare provision and income redistribution), which I think of as the quintessentially neoliberal ideas". In development literature it is examined and accepted that The Washington consensus emerged out of a kind of counter reaction in development economics (3) to what has been termed as rather operationally successful neoliberal revolution against Keynesianism prescriptions of the 1970s.The Washington Consensus, materialized in large and specially built Structural Adjustment Programmes (SAPs) suggested for a substantial portion of the developing countries in the ensuing years of 1980s and 1990s.It was the outcomes of these SAPs that were not along expected lines and which resulted in external criticism of The Washington Consensus itself. Joseph Stiglitz a World Bank Economist was the most prominent insider to offer criticism of the neoliberalism inherent in The Washington Consensus and the body of criticism is now termed as post Washington consensus consensus (4) in the sense that it agrees on drawbacks and weak points of the consensus. This paper examines the critical body of arguments posed in this new consensus. 2.Post Washington Consensus Consensus (5) exemplify in detail the various outcomes of the SAPs, based on The Washington Consensus, which not fell short of mark in their prime objective of achieving economic growth through market deregulation but also created other weak spots.Amin states that SAPs resulted in ," a sharp increase in unemployment, a fall in the remuneration of work, an increase in food dependency, a grave deterioration of the environment, a deterioration in healthcare systems, a fall in admissions to educational institutions, a decline in the productive capacity of many nations, the sabotage of democratic systems, and the continued growth of external debt. "This made Stiglitz look out for an intellectual alternative t economic growth model. An alternative which was not based on sole emphasis on deregulations of all categories of markets to attain economic growth targets. Stiglitz writes about 'a new paradigm for economic development' (6).This idea of anew consensus arrived from Stiglitz when global development financial institutions had undergone a major policy shift after having witnessed the Asian crisis and analyzed its reasons that were traced to deregulated

Anomaly Detection Scheme for Prevention of Online Attacks Dissertation

Anomaly Detection Scheme for Prevention of Online Attacks - Dissertation Example The time parameter reflects any deviation from the normal (duration taken) in disseminating information and receiving of the feedback. The efficiency of communication is therefore slowed down and this cripples the activities of an institution. Hacking of the internet system distorts the original information that was fed and may bring about a jam. All these are prevented by use of highly advanced and sophisticated modern devices that quickly sense and produce signals to notify the comptroller (Chiang, 2004). Data analysis must be undertaken to confirm and ensure only the vital information is online and accessed by the target population. The systems are made in a way that they are able to identify the geographical location of an attacker who can then be easily trailed, and legal action may be taken. The coming attacks may also be blocked by an automated program in the system. Updating should always be done to facilitate prompt detection of attacks. This ensures the system remains at pa ce with any new technological changes. When all security measures are considered, the privacy of an institution remains secured. They remain at the disposal of the authorized authorities. Transmission of information must be sufficient at the shortest time possible. According to Chiang (2004), visualization of system level is done to integrate technology with the systems hardware, software or both. This ensures protection by offering an opportunity to study and analyze visual patterns that indicate any possible attack. Sensors are used to detect and send an alert signal inform of graphs on a screen. Multiple attacks are easily displayed and tracked down from their sources. This calls for a quick action in order to protect the data which includes resetting of the connection. All the forecasting and analysis is done in a data warehouse. This method ensures a quick and smooth action is taken to counteract any attack at the shortest time possible. Selection of heterogeneous threshold and conduct of a proper correlation analysis ensures systems are well set to accommodate large amounts of data and detect any slight attacks at any moment. A web of links is made that connects the major system to several others. A threshold value is also set which sounds an alarm when exceeded. The ease of detection of attacks becomes easier since either of them signals the main server (Chiang, 2004). An internal program is installed to ensure the system is able to detect any foreign data and differentiate self from non-self before sending a signal. The system becomes protected from collapsing and is encompassed with appropriate buffer zones to ensure the best possible results are obtained. Anomaly refers to deviation from the normal way in which information systems operate. This compromises the confidentiality and security of information contained within the system. Any delay in detection and streamlining back to normal may result to great negative impacts. Computers should therefore be protected from any form of attack by installation of a specialized and highly sensitive detector. This is called a detection scheme. It is backed up by additional security features which limit access to specific individuals and from a central point. The system is well cushioned and security guaranteed. Most institutions trust the viability of this security measure.
