Essay on Graves Disease - 1625 Words

Graves Disease The disease was first noted in 1786 by Caleb Hillier Parry 1755- 1822, physician from General Hospital, Bath, England. His account was published posthumously in 1825. However Graves disease is named after the Irish physician who described several cases in London Medical Journal in 1835. Graves disease is also known as Parrys disease. In Europe, the disease is known as Basedows disease. It is the most common cause of thyrotoxicosis (the morbid condition due to over activity of the thyroid gland). The disorder has three major manifestations: Hyperthyroidism with diffuse goiter Ophthalmopathy and Dermopathy The three manifestations need not appear together. Indeed one or two never appear, and moreover,†¦show more content†¦TSH not only stimulates the thyroid gland to churn out more hormones. If in excess, can cause overwhelming cell growth and division to result in goiter. Most T3 and T4 released into the bloodstream are bound to proteins. Only the free component is biologically active and it is this component which decides the manifestations of thyrotoxicosis. The hormones exert their effects mainly by binding to nuclear receptors in cells to affect expression of genes. In the presence of excess T3 and T4, an increase in number as well as affinity of beta-adrenergic receptors in the heart is noted. These receptors facilitate the action of fight, flight and fright hormones ( epinephrine, norepinephrine) which are positively chronotropic ( beat faster) and inotropic ( pump harder) to the heart. This may then lead to cardiac failure in older patients. In fact, mild hyperthyroidism may produce severe disability in patients with underlying heart disease. Hence, all patients with unexplained cardiac failure or atrial arrhythmias should be examined for thyrotoxicosis. Hyperthyroidism also increases the basal metabolic rate, heat production and oxygen consumption (calorigenic action) of many tissues. Body temperature increases slightly and the patient experiences intolerance to heat. Flushing and sweating are just compensatoryShow MoreRelated Graves Disease Essay981 Words   |  4 PagesGraves’ disease was named after Robert J. Graves, MD, around the 1830’s. It is an autoimmune disease indicated by hyperthyroidism due to circulating autoantibodies, which is an antibody that attacks the person’s own body. The immune system attacks the thyroid gland, which causes it to produce too much thyroxine. Thyroxine is a hormone that helps control growth and also regulates metabolism in the body. While the thyroxine levels are high the patient’s metabolic rate increases, which can have an effectRead MoreGraves Disease772 Words   |  4 PagesGraves Disease The most common cause of hyperthyroidism is Graves disease.

Graves disease is an autoimmune disorder and is the most common cause of hyperthyroidism. The thyroid gland is diffusely enlarged and patients usually complain of eye discomfort or, in extreme cases, bulging eyes. This is most commonly seen among young females and affects multiple family members. A toxic nodule is a single nodule or lump in the thyroid gland that over-produces hormones, causing hyperthyroidism. Unlike Graves disease, this is not familial. It is alsoRead MoreGrave Disease : An Autoimmune Disease1096 Words   |  5 Pages Graves’ disease is an autoimmune disease in which the over activity of the thyroid gland causes the overproduction of the thyroid hormone. This disease was described by Robert J. Graves a doctor from Ireland and is also known as Basedow’s disease. Even though there are several disorders that may result in hypothyroidism, grave disease is one of the most common type of hypothyroidism that occurs in 1 percent of U. S population (Anderson 2010). Furthermore, Grave disease is a disease that canRead MoreAn Autoimmune Disorder That Directly Affects The Thyroid Gland1539 Words   |  7 PagesGraves’ Disease is identified as an autoimmune disorder that directly affects the thyroid gland. Characterized as the most common ca use of hyperthyroidism, Graves’ Disease encompasses an overactive, enlarged thyroid gland, which produces an excess of thyroid hormones [1]. Approximately 3% of the United States population is affected by Graves’ Disease and 60-80% of patients affected with Graves’ disease are diagnosed with hyperthyroidism [2].

The hormones it releases are vital in regulating growth and metabolic reaction. The thyroid gland is relatively small (about 20g) and is located at the base of the neck, connected to the windpipe and voicebox. Its structure may be described as ‘butterfly-shaped’ as it is composed of two connected lobes.

Anthony was born February 15, 1820 in Adams Massachusetts to Daniel and Lucy Anthony.Susan was the second born of eight children in a strict Quaker family.Her father, Daniel Anthony, was a stern man, a Quaker abolitionist and cotton manufacturer. He believed in guiding his children, not directing them. He did not allow them to experience the childish amusements of toys, games, and music, which were seen as distractions from the Inner Light. Instead he enforced self-discipline. Susan learned to read and write at the age of three. In 1826, the Anthonys moved from Massachusetts to Battensville, New York.Where Susan attended a district school, when the teacher refused to teach Susan long division, she was taken out of school and taught in home school set up by her father.A woman teacher, Mary Perkins, ran the school.Perkins offered a new image of womanhood to Susan and her sisters.

This was one of the first expressions of feminism in the United States, and it delt with the abuses of woman and children who suffered from alcoholic husbands.In 1849, Susan gave her first public speech for the Daughters of Temperance, and then help found the Womans State Temperance Society of New York.It was one of the first organizations of its time. In 1851 she went to Syracus to attend a series of antislavery meetings.During this time Susan meet Cady Stanton.They became best friends.Susan joined Stanton and Amelia Bloomer in campaigns for womens rights. She would often deliver speeches written by Stanton, who was occupied with her young children. In 1854, She devoted herself to the antislavery movement serving from 1856 to the outbreak of the civil war, 1861.Here, she served as an agent for the American Antislavery Society.After, She worked with Stanton and published the New York liberal weekly, The Revolution (1868-1870) which called for equal pay for women. In 1872, Susan demanded that women be given the same civil and political rights that had been extended to black men under the 14th and 15th amendments. Anthony and Stanton became convinced that pg1ggggwoman would not gain the rights or be effective in promoting reforms until they had the right to vote. So she led a group of women to the polls in Rochester to test the right of women to vote. She was arrested two weeks later and while awaiting trial engaged highly publicized lecture tours and in March 1873, She tried to vote again in the city elections. After being tried and convicted of violating the voting laws, Susan succeeded in her refusal to pay the fine.From then on she campaigned endlessly for a federal woman suffrage amendment through the National American Womans Suffrage Association (1890-1906) and by lecturing throughout the country.Now the newly freed slaves were granted the right to vote by the 15th amendment, women of all races still did not have the right to voteAnthony, Stanton, and Matilda Joslyn Gage published the History of women Suffrage 4 volume (1881-1902), in 1888 she organized the International council of women and in 1904 the International Women Suffrage Alliance.Although Anthony did not live to see her effort fofilled to win the right to vote for women, the establishment of the 19th amendment is deeply owed to her efforts. .u65bcba62313d110cb8a0c0500c5a5bbe , .u65bcba62313d110cb8a0c0500c5a5bbe .postImageUrl , .u65bcba62313d110cb8a0c0500c5a5bbe .centered-text-area { min-height: 80px; position: relative; } .u65bcba62313d110cb8a0c0500c5a5bbe , .u65bcba62313d110cb8a0c0500c5a5bbe:hover , .u65bcba62313d110cb8a0c0500c5a5bbe:visited , .u65bcba62313d110cb8a0c0500c5a5bbe:active { border:0!important; } .u65bcba62313d110cb8a0c0500c5a5bbe .clearfix:after { content: ""; display: table; clear: both; } .u65bcba62313d110cb8a0c0500c5a5bbe { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u65bcba62313d110cb8a0c0500c5a5bbe:active , .u65bcba62313d110cb8a0c0500c5a5bbe:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u65bcba62313d110cb8a0c0500c5a5bbe .centered-text-area { width: 100%; position: relative ; } .u65bcba62313d110cb8a0c0500c5a5bbe .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u65bcba62313d110cb8a0c0500c5a5bbe .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u65bcba62313d110cb8a0c0500c5a5bbe .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u65bcba62313d110cb8a0c0500c5a5bbe:hover .ctaButton { background-color: #34495E!important; } .u65bcba62313d110cb8a0c0500c5a5bbe .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u65bcba62313d110cb8a0c0500c5a5bbe .u65bcba62313d110cb8a0c0500c5a5bbe-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u65bcba62313d110cb8a0c0500c5a5bbe:after { content: ""; display: block; clear: both; } READ: Delinquent Behavior EssayOn July 2, 1979, the U.S Mint honored her work by issuing the Susan B.

Reality and Imagination essays

Reality and Imagination essays Reality can be comforting or agonizing, it depends on whos reality is in question. Tennessee Williams depicted reality and what it can do to people in The Pulitzer Prize winning play A Streetcar Named Desire. The story is about an unmarried thirty year old woman who creates a new magic reality for herself to escape the cruelty and bitterness of the real world. She comes to New Orleans from a once wealthy estate plagued with family death and eventually loses the estate Belle Reve to unpaid mortgage. She slowly comes to believe her fantasy world is the real world and eventually cant tell them apart any longer. Her escapes from the real world are illustrated by her constructive compulsive mis-truths, fear of being seen in well lit areas, frequent long baths and excessive drinking. Blanche Dubois desires to escape her real life and to embrace upon the cushion of a magical fantasy world which she creates for herself. One of the most prominent escapes is her drinking and the large quantities of it. Blanche has a younger sister, Stella, who moved to New Orleans when the ordeals of Belle Reve were getting out of hand I stayed and struggled! You came to New Orleans and looked after yourself. I stayed at Belle Reve and tried to hold it together!. Blanche arrives and shortly thereafter is drinking. She has a tumbler of whiskey and downs it quickly while smoking simultaneously. Blanche proclaims her limit is one drink but it is evident she is using the alcohol as an escape because of how fast she drinks it following a fabrication about her employment relief. Several nights into the play, there is a poker game hosted at Stella and Stanleys, her husband, house. Blanche often drinks in large quantities to ease her nerves, hard alcohol, not beer I hate beer and usually prior or following her arsenal of Truth is bent and twisted by Blanche very ...

Technical factors affecting e-banking development in Iran Dissertation

Technical factors affecting e-banking development in Iran - Dissertation Example Research questions The purpose of this study is to get greater understanding of e-Banking phenomenon and find out its implementation obstacles in Iran. In the conduct of the collection of data; both primary and secondary data, it is important that the researcher has a guide on the kind of data to collect and which ones to ignore. In doing this, the following research questions have been set to guide the researcher on the exact data to go after. Therefore, the researcher tries to reach this goal by answering the following questions. 1 What have been the hindrances to the advancement of e-banking in Iran? Problem Overview In recent years acceptance of e-Banking has been rapid. In many west countries like Finland over 50% of bank customers use e-Banking services. On the other hand some evidence shows half of new customers that have used e-Banking for the first time, do not continue using this channel as an active customer.(reference needed) the development of new technologies in communi cations and information practices and the emergence of new services and increasing expectations and needs for banking services market caused our public and private banks to compete for providing new e-banking services. E-banking in recent decade has been carried out with various implementations in our country by a variety of public and private banks. Now each bank more or less seeks for efficient use of this new technology. However, it seems the use of e-banking is still not institutionalized in the culture of our people, and customers still do not use this technology with trust for large financial transactions.

The C entral Bank of Iran observes that not many companies and organisations are taking advantage of e-business as penetration rate in e-business is still very low. Iranian banks have made huge investments into e-business but this has not succeeded in changing the trend. According to BBC news 60 †¬percent of Iranians go to banks only to receive or pay cash to the banking network. Iranian banks talk about the spread of e-banking while Iranians spend a lot of time to pay the bills for water, electricity, gas, phone, or transferring money to other accounts and sometimes they stay in line for hours to receive or pay cash.

LITERATURE REVIEW 7 4. RESULTS AND DISCUSSION. 44 6. CONCLUSION 54 Reference list 55 1. INTRODUCTION. 1.1 Problem statement. The possibility of real time and low cost digital filtering emerged in when general purpose of microcomputers were introduced in the 1970s. The earlier designed digital filters had limited precision and speed which limited them to a restricted their application to simple algorithms and low frequency . In the 1980s, in its historical development DSP Chips which were of higher special cost were introduced (Tomlinson 1991). This contained an on chip D/A converter were incorporated and later improvements in their speed and complexity were advanced by ICS . This gave birth to the advanced digital filter design of today ( VolKenberg, 1987). Availability of F.P.G.A series kits helps researchers to take practical designs of semi adaptive band pass filters from low to high frequencies. It is on this basis that this project is designed to provide a high factor and high performance factor in attenuating frequencies which are undesirable for certain applications like the elec trocardiogram. 1.2 Objective The objectives of this project are: To inter-grate a low pass and high pass digital filters in a substrate known as band pass filter. To design FIR band pass that can help to extract low frequency of between 0.2-0.5 Hz 1.3 Scope of work The scope of this work is to design and develop a finite impulse response band pass digital filter. The following lists of objectives must be completed with the following in mind: 1. The scope of this project is making literature review which will survey on the magazine, journal, textbooks or conference papers. 2. During literature review, all the information such as theory and design of a digital filter will be explored. 3. Calculation based on Butter-worth and Chebyshev response will be done 4. Entering of the filter characteristics to generate coefficients using the FDAT tool block. 5. After the coefficients have been generated by the use of the FDAT tool block, design simulation using the FIR block will be done. 6. Th e last step in the finite impulse response band base filter design will be to hardware verify the performance of the hardware in the loop. 7. The preliminary work will use MATLAB tools and the result will compare with the theoretical result. 8. Finally, fabricate and make measurement for analysis result will be made based on the designed device. 1.4 METHODOLOGY This project will start with the background study of band pass basic concept through hole
