How Brian Imaging Could Help Predict Alzheimers Essay

How Brian Imaging Could Help Predict Alzheimers - Essay Example To date there is a lack of reliable drug that can be used to decelerate the progress of Alzheimer’s disease. Although many drugs have been tested scientists and drug manufacturers blame the timing when these drugs have been administered to patients of the disease. They claim that many of the drugs are administered at a time when the progress of the disease makes it difficult for any significant improvement to take place. The pharmaceutical company Eli Lilly developed gamma secretase inhibitor but this drug didn’t prove successful. Sangram Sisodia, director of the Center for Molecular Neurobiology at the University of Chicago explained that the drug was tested on the wrong group of patients. New studies, however, have shown that there is hope for Alzheimer’s patients. Recent presentations at the Society for Neuroscience conference recently held in San Diego showed that brain imaging may help in the prediction of the disease. Researchers believed that changes in the brain will help to qualify patients to undergo clinical tests of new drugs. They are also hopeful that brain imaging will help in the selection of persons for clinical testing before dementia is developed. Reliable drugs testing can become possible if persons found with mild cognitive impairment are used for clinical testing as indicated by recent researches. Not everyone who has this condition will develop Alzheimer’s as revealed by a graduate student of Rush University Medical Center in Chicago. The study highlighted the substantia innominata section of the brain. Of the 47 persons who had mild cognitive impairment, 22 developed Alzheimer’s over a six year period. They were found to have significant thinning in three connected areas of the cortex involved in memory, attention, and integration of sensor and motor integration. A second study revealed that the caudate nucleus section of the brain shrunk significantly in elderly persons diagnosed with

Pagan Arabia and Islamic Monotheism Essay Example | Topics and Well Written Essays - 250 words

Pagan Arabia and Islamic Monotheism - Essay Example The physical world is all that existed, and there was no hereafter and no accompanying punishment or reward. Their concept of man's role in the universe was one of hedonistic indifference toward the weak, economic and emotional greed, as well as abusive powers and control of the marginal members of society. It was a world gone mad. Fortunately, Muhammad was charged with shifting this wicked paradigm. Allah instructed Muhammad to spread the message the Divine Essence was One sovereign Lord over all creation. After this life a Hereafter awaits what ones hand puts before them in this life will be their reward eternally. This life is temporary. Our ultimate existence lies in the hereafter. As such, human beings should act in a way that is fair toward his fellow, protective toward the disenfranchised, and obedient to the One True God. The cosmological characteristics of pre-Islamic Arabia differ starkly from the transcendental features of Muhammad's message. They differ in the basic concept of the divine, the existence and nature of the hereafter, and role of humankind in the universe. Further study would demonstrate how Muhammad's contemporaries diverged from the traditional tribal ethics codified in the Qur'an and Sunnah.

Moral Autobiography Essay Example | Topics and Well Written Essays - 1250 words

Moral Autobiography - Essay Example Genetics made me possess certain innate qualities that I find difficult to erase. However, it seems to me that socialization had a larger role in deciding my outward behavior (Text). For example, my present skills, knowledge, values, emotions and my role are all decided by the society. Admittedly, the very beginning of my socialization was from family followed by peers, school and the wider society. Thus, the beginning of my ethics was from my family, especially my parents. As my father is a Jew and mother has no affiliation with any religion, I grew up with no influence of any religion on me. However, the values of ethics that developed in me were mainly imported from the values I observed in my parents. In the early stages of my life, that is play, I imitated the surroundings I saw. I played doctor, police, father and teacher. At this stage, even without my knowing, the basic values of ethics were getting inculcated. Evidently, in the beginning, my ethics was entirely normative in nature. Admittedly, it was somewhat in the kind of the Golden Rule that one should do to others what one wants others to do to one. I learnt the fact that I should respect my parents, teachers and all elders. In addition, certain fundamentals like killing or harming is bad, it is good to help others were also incorporated into my ethical repertoire. Here, the tenets of Role Theory seem useful. According to the theory, the observable social behavior of people is like carrying out ones role in the society. For example, as a child I was made to obey my parents and all other elders I met. In addition, as the Symbolic Interaction Theory suggests, I started developing the concept of self. As I was defining myself, I found myself taking the role of a son and a student. As a child, I used to observe and play the roles of various people. As I imitated my father, I observed how my father has been with me, and thus I got the ideas of ethics. Admittedly, at this stage, I got no influence of rel igion, and the only ethical aspects of my life came from my parents' advice and observation I made. As a result of the normative nature of my ethics, I can say it was virtue ethics that I upheld in the beginning. It was inculcated not as my duty, but as a virtue I should develop. If I try to mention them, the very first thing is that one is supposed to respect all elders, especially parents and teachers. In addition, I found that unnecessarily harming anyone is morally wrong as Symbolic Interaction Theory claims. As I found that others do not engage in such activities that are harmful to others, I realized that harming others is immoral. However, as I reached adolescence and started mingling with may people, I reached what is called utilitarian concept. I found the fat that if I behave well with others, there is the feeling of wellbeing in the group I live. In addition, there was the development of deontological idea that I can expect in return, the kind of virtue I produce. In addi tion, I rightly followed the principles of virtue ethics by trying to develop a eudaimon life that gives satisfaction. Admittedly, this took place mainly because my parents, especially my mother taught me that if one has virtue in life, or if one always does good things in life, one will have peace and thus will be a good human being. However, reaching adolescence and reaching the Christian school, my concepts of ethics developed and altered a lot. Admittedly, Christian ethics varies from ethics in general. While Christian ethics stress on what

The Effects of Mass Media on Society Research Paper

The Effects of Mass Media on Society - Research Paper Example One of these is video games which are products of man’s quest for excitement and entertainment. In this regard, this essay is written with the objective of determining the effects of video games on society. It would initially start on the origins of video games and rationale for playing video games. The discourse would also present the advantages and disadvantages of video games to find out their implications to the users and to society, as a whole. The exact date for the creation of video games could not be pinpointed due to its reference and interrelationships with people, games, companies and culture which actively influenced it. According to Herman, Horwitz, Kent & Miller (2009), video games started with Ralph Baer’s assignment of creating a television set incorporated with a game. They averred â€Å"it would take another 18 years for his idea to become a reality, and by that time there would be other people to share in the glory, like Willy Higinbotham, who designed an interactive tennis game played on an oscilloscope, and Steve Russell, who programmed a rudimentary space game on a DEC PDP-1 mainframe computer. And then there was also Nolan Bushnell, who played that space game and dreamed of a time when fairground midways would be filled with games powered by computers.† (Herman, Horwitz, Kent & Miller, 2009, par. 1) The golden age in video games was identified as spanning the years 1978 to 1981with the emergence of famous brands synonymous to video games such as Atari, Nintendo, Magnavox, Microvision and Intellivision, among others. (Herman, Horwitz, Kent & Miller, 2009, 3) The evolution continues until brands such as Sega, Game Boy Playstation and Xbox remain imprinted in the minds of millions of patronizers. But what exactly are video games? Allwords (2009) define video game as â€Å"a style of game existing as and controlled by software, usually run by a

Macro and Micro Economics. What is the subject matter of economics Essay

Macro and Micro Economics. What is the subject matter of economics - Essay Example The scope of Economics revolves around many things some of which are factor pricing, product pricing, income, demand, economic growth and welfare. The study of economics attempts to gain a glimmer of light on how and why the wealth of the world gets produced, distributed and finally consumed. It not only examines the local market, but it also everything at the global levels. Class structures and wealth distribution, the role of government and politicians, demand and supply of products and services, division of labor and other countless factors are all encompassed in economics. It attempts to explain the production system in the world and why they function the way they do (ILO, 2013). Arguably, one of the most inalienable factors in the definition of the subject matter of economics is division of labor. According to International Labour Organization, the current distribution of labor is a positive factor contributing to the economic climate today. Labor gets distributed not only betwe en companies and countries but also within a company. Wage disparity occurs between the laborers and capitalists, a condition that results from division of labor. The laborers will thus have low buying powers in comparison to the business owners. This means that their economic standard will always be lower than that of capitalists. Division of labor is thus effective as a clear vision of the subject matter of economics. Economics study is not effective if we fail to discuss the two main divisions of economics namely macroeconomics and microeconomics. Macroeconomics is a branch of economics which looks into, the behavior, decision-making and performance of an economy as a whole and not as individual markets. The World Trade Organization makes use of GDP, unemployment and price indices in a bid to understand how the economy functions. In macro economics, models get used to explain the relationship between such factors like national income, output, consumption, unemployment, savings, i nflation and international finance (IMF, 2013). Macro economics is such a broad field of study and there are two main areas of research considered emblematic of the discipline. This is the attempt to give an account of the causes and consequences of short-run fluctuations in the national income (the business cycle) and an attempt to understand the determinants of a long-run economic growth. In most cases, macroeconomic models and their focuses get utilized by governments to assist them in their development and evaluation of economic policies. Some of these policies include the monetary policies, fiscal policies and comparison policy. Further, macroeconomics encompasses output and income, unemployment and inflation & deflation as the three major variables of its research (IMF, 2013). Thus, the subject matter of macroeconomics revolves around the three aspects of national aggregates; stability, growth and stability of the community at large. Most variables of macroeconomics get relate d with employment, inflation, unemployment issues and import and export matters of a nation or between nations. Microeconomics is the branch of economics that analyzes market behaviors at a level of individual consumers and firm. This it does in the attempt to understand the underlying decision-making processes of firms and households. It majorly concerns itself with the interaction between individual buyers and sellers (IMF, 2013). In particular, macro economics mainly focuses on supply and demand patterns, as well as price and output determination at these individual markets. The strength of microeconomics crops from the simplicity of its underlying structure and its closeness in contact with the

Fermentation Kinetics of Different Sugars Essay

Fermentation Kinetics of Different Sugars - Essay Example The findings achieved through the experiment showed an increased rate of fermentation in tubes with glucose and sucrose as the substrate while lactose showed a massively decreased rate of fermentation. The addition of sodium fluoride also caused a decreased rate of fermentation. Analysis of the complete data suggested that the carbohydrates used by Saccharomyces cerevisiae for fermentation play a great role in the final rate of fermentation. Keywords: Saccharomyces cerevisiae, fermentation, carbohydrates, magnesium Fermentation Cells and tissues irrespective of belonging to animal or plant have a minimum requirement of energy. Different processes such as synthesis of molecules, transportation, DNA replication and cell repairs have varying requirements of energy. To successfully complete these processes cells undertake many metabolic processes to achieve their supply of energy. Glucose being the most important carbohydrate and the end product of almost all food sources is the beginnin g point of these metabolic processes. Energy conversion starts from the process of glycolysis. As explained by Agrimi et al., (2011) glycolysis begins with the entry of a single glucose molecule and terminates with the production of two pyruvate molecules. The process immediately yields four ATP molecules. However, with the consumption of two ATP molecules at two different steps in the cycle, the net production via substrate level phosphorylation turns out to be two. Although the process itself is not affected by the presence or absence of oxygen, the final production of the ATPs is hugely affected under hypoxic conditions as only 2 ATP molecules per glucose are produced instead of 36 ATP molecules per every glucose molecule. Depending on the availability of oxygen the pyruvates produced at the end of glycolysis are either shuttled into either cellular respiration / Krebs cycle or they are used in the process of fermentation. Fermentation has been derived from a Latin word ‘fe ver’ meaning to ferment.
