Function, Structure, Synthesis And The Use Of The Protein...

The purpose of this paper is to discuss the function, structure, synthesis and the use of the protein elastin (ELN), which encodes for one of the two elements of elastic fibers in the human body (NCBI 1). Addressing the fundamental aspects of the protein will allow us to explore the potential applications and implications of the protein if it has been modified. Introduction and Function Elastin is the one of the key components in the elastic property of tissues found in human tissues such as arteries, lungs, and elastic cartilage to name a few (Jacob, Sauvage, Osbourne 1). Elastin is mainly composed of amino acids glycine and proline, which are hydrophobic and are combined with lysine residues in crosslinks (NCBI 1). It plays a fundamental role in the recoil of tissues after being stretched, which is critical in maintaining the cells health (Weiss 1). Thirty percent of the dry weight of the extracellular matrix (ECM) in arteries is comprised of the protein elastin, hence, making it an essential part of human tissue (Krettek, Sukhova, Libby 1). Elastin can be found abundantly in the dermis of the skin, the arterial walls, the pulmonary tissues, which helps with the expansion of the lungs upon breathing and the recoil upon exhaling (Krettek, Sukhova, Libby 1). Elastin in the skin is elastic tissue intertwined with other components in the dermis through fibers that a re interconnected (Krettek, Sukhova, Libby 1). The skin is dense with elastic tissue, which allows for the

Mexico Democracy Free Essays

Democracy requires several elements to succeed and grow. The leaders of a democracy must respect the boundaries they are given. Freedom of the press is an essential element of modern democracy. We will write a custom essay sample on Mexico Democracy or any similar topic only for you Order Now People must be willing to participate and support the system of government. Classes may exist in a democracy, but should not be perceived as a detriment to participation in a democracy. Cultural and ethnic cohesion will support a ‘group think’ toward policy and ideals. Mexico during its history lacked several of the elements for a successful democracy.Mexican independence was initially a continuation of Spanish colonialism. The government was not able to see a way forward without continuing policy. Every new nation has a bumpy time converting from monarchy to democracy, but Mexico faced a difficult cultural change. The Catholic Church had a strict hierarchy that also permeated the culture of Mexico and the indigenous people did not have a fair voice in the new government. The wars with France, the US and Texas did not help stabilize a new democracy and led to dissatisfaction and a non-cohesive government.Democracy could not grow in this environment and led to further dissatisfaction with the ‘democracy’ in Mexico. This allowed for a long period of dictatorship under Porfirio Diaz. Mexico was an agrarian society at the time and the lack of education led itself to a dictatorship. Although Diaz brought science and industry to Mexico, he did not allow democracy to flourish under this success. Diaz was more concerned with keeping centralized power of the country and did not allow mass participation in government. Any dissent was silenced. The press was not free and was used by the government to strengthen the Diaz government.Without freedom of the press and centralized power Mexico could not gain true democracy. A free press allows citizens the ability to criticize and form opinions of their government. Mexico did not have this ability under Diaz. The growth of the Haciendados continued to keep democracy at bay. With an uneducated and rural population, it is difficult to bring the ideals of democracy to the masses. One of the elements of a successful democracy is a literate voting block. Class seperation, education and the disenfranchisement of citizens continued to keep democracy at bay.Following the revolution of 1910, the leaders of the revolution were unable to gather a productive government. The ideals of revolution were difficult to govern; therefore the government reverted to learned behavior of the previous dictatorship. The cultural divide between indigenous tribes, Crillios and Spaniards was a further detriment to equality under the law in Mexico. The industrial revolution had already started tapping Mexican resources for production in the US and other countries. Corruption was continued and allowed to flourish to keep rebellious elements of the country under control.A democracy cannot move forward with a government that allows corruption. Fuentes speaks of the problems with a strong sense of national cohesion or â€Å"mexicaness. † A democracy requires a sense of strength as a people. One of the most famous lines from American democracy is â€Å"a government of the people, by the people, for the people. † Mexico does not have a government that they see in these terms. The continued struggle to gain land rights and justice in the Mexican system does not allow the citizenry to feel a part of their own country and government.The late 20th Century allowed for further economic growth, but governmental policy did not allow for the social structure to continue a growing democracy. Corruption has continued to plague Mexican politics leading citizens to distrust elections. The resent elections in Mexico have been as widely criticized as the elections of the early part of the century. Mexico continues to have a strict class system, uneducated indigenous people and cultural separation. Democracy will continue to struggle to grow in a rocky environment until Mexico builds the social structure to support an educated society with further cohesion as a people.

Tom Sawyer (1695 words) Essay Tom SawyerTom Sawyer is a boy who is full of adventures. In his world there is an adventure around everycorner. Some of his adventures have lead him into some bad situations but with his good heart and brightmind he has gotten out of them. Tom lives with his aunt Polly, his cousin Mary and his bother Sid.

Tom wrote on a wooden board Huck Finn and Tom Sawyer swear tokeep mum about this and they wish they may drop down dead in their tracks if they ever tell and rot, thenin their own blood they signed their initials TS and HF. A few days after that incident Tom, Huck and Joe decided to go and become pirates because noone cared for their company anymore. They stole some food and supplies and then they stole a raft andpaddled to an island in the middle of the Mississippi River. They stayed and pirated for several days, thenthey all became so home sick that they could not bear it anymore. The next day Tom, Huck, and Joeshowed up for their own funerals and there was much thanks and praise. The next big event in the town was the trial of Muff Potter for the murder in the graveyard. Thewhole town believed Injun Joe, and poor Muff was sent to a temporary jail cell for aweek. At the end ofthe week he was to be hung unless some one in court had proved him innocent. While Muff was in jailtemporarily he was not alone. Every day Tom and Huck would go and talk to him through the jail cell barsand on occasion bring him food. On the last day of court, to everyones surprise they called Tom Sawyer tothe stand. Then the man asked him where he was on the 17th of June he said In the graveyard. Thenwhen he asked who he saw do it he said with all his courage he said Muff didnt do it. It was Injun Joe!and with that Injun Joe jumped out the window and ran away. Tom and Huck decided that they wanted to become rich so they went to go and find buriedtreasure. Tom and Huck dug under trees all day and night but found nothing, then Tom said that theyshould go and dig for treasure in a haunted house. They went back two days later and went to a hauntedhouse. Both the boys were scared but they both went inside anyway. The boys dared each other to goupstairs, so of course they went up and looked in closets for treasure but found nothing. Suddenly the boysheard two men talking and then come inside.Both of the boys got down on the floor and then they heardthe voice again, it was Injun Joe. Injun Joe and the other man had a bag of money and decided to bury itthere. Tom and Huck could hardly contain themselves because they would steal it as soon as Injun Joe left. .u28f32c9817ef630220dae8fb07b0bb00 , .u28f32c9817ef630220dae8fb07b0bb00 .postImageUrl , .u28f32c9817ef630220dae8fb07b0bb00 .centered-text-area { min-height: 80px; position: relative; } .u28f32c9817ef630220dae8fb07b0bb00 , .u28f32c9817ef630220dae8fb07b0bb00:hover , .u28f32c9817ef630220dae8fb07b0bb00:visited , .u28f32c9817ef630220dae8fb07b0bb00:active { border:0!important; } .u28f32c9817ef630220dae8fb07b0bb00 .clearfix:after { content: ""; display: table; clear: both; } .u28f32c9817ef630220dae8fb07b0bb00 { 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; } .u28f32c9817ef630220dae8fb07b0bb00:active , .u28f32c9817ef630220dae8fb07b0bb00:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u28f32c9817ef630220dae8fb07b0bb00 .centered-text-area { width: 100%; position: relative ; } .u28f32c9817ef630220dae8fb07b0bb00 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u28f32c9817ef630220dae8fb07b0bb00 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u28f32c9817ef630220dae8fb07b0bb00 .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; } .u28f32c9817ef630220dae8fb07b0bb00:hover .ctaButton { background-color: #34495E!important; } .u28f32c9817ef630220dae8fb07b0bb00 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u28f32c9817ef630220dae8fb07b0bb00 .u28f32c9817ef630220dae8fb07b0bb00-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u28f32c9817ef630220dae8fb07b0bb00:after { content: ""; display: block; clear: both; } READ: The most dangerous game EssayInjun Joe was digging a hole with his knife when he hit something, it was a box of money. Injun Joedecided to take all of the treasure and hide it in number two und!er the cross. When Injun Joe and the other man left Tom and Huck were furious because they thought thatall of the treasure was rightfully theirs. A few days later Becky had her long awaited picnic, and they all went to McDougals cave. Tomshowed Becky around and while they were exploring they got lost, with only a small slice of cake to eatthat Tom had shoved in his pocket the day before along with several candles.

When Huck has just about given up, InjunJoe and another man left the tavern with so bags. Huck followed them to Widow Douglas house andlistened in on their plan. Injun Joe was going to hurt Widow Douglas because of what her deceasedhusband did to him. Once Huck had heard the plan he ran to the Welshmans house and he told the story tohim. Old Welshman and his sons went to Widow Douglass house with their guns and had a shootout withInjun Joe and his partner. In the end no one was hurt and Injun Joe and his partner escaped.

One Of The Smartest People Ever To Live, Albert Einstein, Changed Our

One of the smartest people ever to live, Albert Einstein, changed our society's development forever with his views, theories, and developments. Einstein was born in Ulm, Germany on March 14, 1879. He was the only son of Hermann and Pauline Kech Einstein. He spent his youth in Munich, where his family owned a small electrical equipment plant. He did not talk until the age of three and by the age of nine, was still not fluent in his native language. (Discovering World History) His parents were actually concerned the he might be somewhat mentally retarded. His parent's concerns aside, even as a youth Einstein showed a brilliant curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself Euclidian Geometry. Einstein hated the dull regimental and unimaginative spirit of school in Munich. (Albert Einstein's Early Life) His parents wisely thought to transfer him out of that environment. Although Einstein's family was Jewish, he was sent to a Catholic elementary school from 1884 to 1889. He was then enrolled at the Luitpold Gymnasium in Munich. In 1894, Hermann Einstein's business failed and the family moved to Pavia, near Milan, Italy. Einstein was left behind in Munich to allow him to finish school. Such was not to be the case, however, since he left the gymnasium after only six more months. Einstein's biographer, Philip Frank, explains that Einstein so thoroughly despised formal schooling that he devised a scheme by which he received a medical excuse from school on the basis of a potential nervous breakdown. He then convinced a mathematics teacher to certify that he was adequately prepared to begin his college studies without a high school diploma. Other biographies, however, state that Einstein was expelled from the gymnasium on the grounds that he was a disruptive influence at the school. (Discovering World History) In 1895, Einstein thought himself ready to take the entrance examination for the Eldgenossiche Technische Hochschule (ETH: Swiss Federal Polytechnic School, or Swiss Federal Institute of Technology), where he planned to major in electrical engineering. When he failed that examination, Einstein enrolled at a Swiss cantonal high school in Aarau. He found the more democratic style of instruction at Aarau much more enjoyable than his experience in Munich and soon began to make rapid progress. He took the entrance examination for ETH a second time in 1896, passed, and was admitted to school, although other sources state that he was admitted without examination on the basis of his diploma from Aarau. ETH had little appeal to Einstein, however. He rarely attended classes and hated studying for examinations, although he did graduate with a secondary teaching degree in 1900. He became a teacher of mathematics and physics in secondary school. (Albert Einstein's Early Life) As a teacher Einstein was unable to find a regular teaching job. Instead he was a tutor in a private school in Schaffhausen. With his extra time in 1901, Einstein published his first scientific paper, "Consequences of Capillary Phenomena.? In 1902 he was hired at the patent office until 1909. During this period of time, he was wed to his first wife Mileva Marie and had two sons and a daughter. There are no records of his daughter due to the fact that she was given up for adoption, they simply did not want her. (Discovering World History) In 1905, during a single year, Einstein produced a series of three consecutive papers. These are among the most important in twentieth-century physics, and perhaps in all of the recorded history of science for they revolutionized the way scientists look at the nature of space, time, and matter. (Discovering World History) The series of three papers dealt with the nature of particle movement known as Brownian motion, the quantum nature of electromagnetic radiation as demonstrated by the photoelectric effect, and the special theory of relativity (Discovering Science). The first paper of the series, "On the Movement of Small Particles Suspended in Stationary Liquid Demanded by the Molecular-Kinetic Theory of Heat,? dealt with a phenomenon first observed by Scottish Botanist Robert Brown in 1827. Brown stated that tiny particles, such as dust particles, move about with a zigzag motion when suspended in water. The visible movement of
