Literature Review for Denaturing Gradient Gel Electrophoresis

Denaturing Gradient Gel Electrophoresis (DGGE) is a robust process by which point mutation mass be seeed. It depends upon polymerase chain reaction (PCR) products which change at different temperatures depending upon if they contain homoduplex or different products from both wild character reference and mutated genes or heteroduplex or combined strains of wild type and mutated DNA strains. Heteroduplex products contain a mismatch and therefore melt more(prenominal) quickly than heteroduplex products (Roelfsema and diaphysiss, 2005, pp. 79).DGGE is used most effectively to mention point mutations in genomic DNA that cause heritable diseases, to identifiy previously unidentify mutations in recessive genes, analysis of DNA from cancer tumors, and by targeting ribonucleic acid, assessing the number and type of bacterium species in soil, water, and the human body (ibid, pp. 84). The DGGE process has many complicated step that entail outpouring and error starting with designing the proper Gradient Gel so that the PCR product will bow matchless end as a double strand, quickly denature and then stop progressing and bother in place.First the PCR product must be designed using special software that analyses the melting curves of possible PCR products. In order to keep the DNA stuck in place once the denaturing has occurred, a GC secure consisting of a string of 40-60 nucleotides must be attached to the PCR primer resulting in a high denaturing temperature at one end and not the other. In addition, the Gradient colloidal gel must be prepared mighty with a 30% gradient and adjusted so that the DNA gets trapped directly in the warmness (ibid, 80).Finally, in the most technically difficult step, a constant temperature of 60 degrees Celsius must be achieved in which to perform the electrophoresis. After this the gels are soaked in a 0. 5XTAE containing ethidium bromide to visualize the DNA. Once these steps are completed successfully, the results are very c lear, and seen quickly. If large numbers of samples beget to be screened, DGGE is very original and cost effective(ibid, 85). The following is a summary of some of the recent uses of DGGE and findings of researchers who have been exploring new territory in their fields through the use of DGGE.This review aims to highlight the strengths and weaknesses of DGGE and its most effective applications. In a dissect led by J. Walter of the University of Stuttegart in Germany, 16S rhibosomal primers were also used to detect lactic acid bacteria in human bowel movement. Subjects were given the probiotic strain lactobacillus rhamnosus DR20 to drink, and while cultural rules only detected the strain in one of the subjects, DGGE detected it in both.In addition, the food associated samples did not appear in the rosa agar polishs, but were homely in the DGGE profile (Walter, J et al, 2001). This shows the sensitivity and reliability of DGGE methods, and its applicability to human microbiolo gy. Another study of faeces conducted by Maukonen et al. concluded that DGGE was an effective way to establish the stability of certain groups of gastrointestinal bacteria. They successfully complete the stability and diversity of the Erecta group by using DGGE to study the bacteria from 12 subjects (Maukonen et al, 2002).Applications to the study of sensual faeces uncovered that DGGE is effective in identifying complex systems such as Heliobacters which are difficult to culture (Al-Soud et al, 2003). At the University of Wales in Cardiff, a team of researchers led by Charlotte E. Davies studyd bacterial microfloras of healing and nonhealing chronic venous leg ulcers using both cultural and 16S rhibosomal PCR-DGGE methods. PCR-DGGE analysis institute a much higher interference of pseudonomads in nonhealing wounds than was apparent in cultural analysis alone (Davies, C et al, 2003).This proves the applicability of DGGE to human microbiology and its usefulness in identifying cau ses of illness. Similar results were obtained in studying Hypophatasia at the Barnes-Jewish Hospital Research Institute. DGGE was used to identify mutations in severely affected patients and was found 100% effective in identifying recessive mutations. In addition it identified eight new mutations and one new pleomorphism of hypophatasia confirming its genotypic variability (Mumm, S et al, 2002).DGGE can therefore be a powerful tool in diagnosing hypophatasia and other genetic diseases. Italian biologists used 16S rDNA PCR-DGGE and ISR-PCR methods as tools to differentiate between strains of staphyloccus isolated from fermented sausages. They obtained species specific profiles using DGGE and combining the two methods allowed them to identify 10 species and an additional 7 groups. They concluded that combining the two microbial techniques was what led to their success (Blaiotta, G et al, sep 2003).Corroborating this evidence of the need to use DGGE in combining with other techniques when studying food microbiology, a study of Cassava root fermentation in Brazzaville, Congo determined that the most effective method of isolating and identifying microbial communities in Cassava starch fermentation was to combine culture and DGGE methods. They found that DGGE failed to detect pure cultures recovered from enrichment and yet detected other species not apparent in any of the cultural methods used (Miambi, E, Guyote, JP and Ampe, F. , 2003).These results suggest that DGGE, while reliable and sensitive, is dependant upon other methods to complete a profile of the microbiological communities. Strides have been made to understand and identify the ecology of microbial communities, such as the work done at the University of notingham. Researchers used PCR-DGGE analysis focused on the V3 and V4-V5 regions of 16S genes to identify and lactobacillus and Staphlyococcus bacteria in stilton cheese. They then used blossoming in Situ Hybridization (FISH) experiments to identify t he spatial ar trudgement of microbial species in the dairy matrix.This allowed them to conclude that there are specific ecological reasons for microbial growth in cheese, and that there are real applications of the combination of DGGE and FISH to optimize food fermentation and preservation of traditional products (Ercolini, Hill, Dodd, Jul 2001). DGGE also has applications to farm production as seen in de Olivera et als study of soil rhibosomes, which concluded that DGGE bears fingerprinting of rhibosomes useful in find the effect of agricultural practices on soils.This can help in the proper amendment of soils and monitoring of pesticides (de Olivera et al, 2006). Recognizing the usefulness of DGGE in identifying and categorizing microbial communities, and the need for more effective identification of which DNA regions to study, Zhongtang Yu and key Morrison performed a test to compare DGGE profiles across hypervariable (V) regions taken from the same DNA regions, and identify t he most useful V regions to study in gastrointestinal microbiomes.Their recommendation is that amplification of the V3 or V1 regions of rrs genes gives the best result, but when doing a longer amplification, the V3 to V5 or V6 to V8 range should be targeted (Yu and Morrison, 2004). DGGE has been used successfully in oceanography to identify and isolate protists that are so fiddling they lack taxonomic features and are too unstable to be studied by traditional means.Biologists at the Woods Hole Oceanographic Institution studied protistan assemblages from the Antarctic using DGGE and were able to determine that microenvironments significantly impact assemblages and that significant genetic diversity exists in each microenvironment (Gast, Dennett and Caron, 2004). Building on the sensitivity of DGGE in identifying genetic differences, biologists in Germany identified an entirely new phylogenic group of Eukariyotic bacteria in the deeper layers of tidal flats. Their technique included using primers targeted at the 18S rRNA gene.They were also able to establish distant relationships between Eukaria and grazers and deposit feeders, proving DGGEs applicability to taxonomy. Scientists at the University of Montana also recognized DGGEs usefulness in identifying unculturable communities and developed a way to actualize these communities more visible by DGGE. They first put the communities through GC fractionalization to make the study size smaller which allowed previously undetectable or underrepresented bands from the full community analysis to be seen (Holbien et al, 2004).Seeking to improve the sensitivity and versatility of DGGEs application to microbial ecology as well as provide a way to compare and standardize gradient gels, Neufeld and Mohn of the University of British Columbia tested the use of Fluorophore-Labled primers. They found that fluorophore greatly helped intralane normalization, was relatively cheap, and allows DGGE versatility including running RN A and DNA derived patterns in the same lane (Neufeld and Mohn, 2005).ReferencesAl-Soud, Waleed Abu Bennedsen, Mads On, Stephen L.

Negative Aspects of Reality Shows

In recent years we have give earn how the reality shows have Increasingly Invaded our screens, and there is something that captivates people to the point that change their way of life and are carried away by this fever. virtually of the people who watch this kind of shows believe that all what they see is real so they begin to tactual sensation identify with them. The sense of hearing imitates they behaviors and most of the time it Is negative.They turn violent, Irritable and susceptible to reactions. A big helping of people who watches this believe that their way of being is normal, but it is not like that. There are indisputable manners or behaviors that we are used to watch, but it doesnt mean it is normal at the point that we intromit it as a way of life. What is true about this is that producers control everything and can alter or wind the actions of the actors. The actors are aware of this because when they sign their contract It Is specified over there.So, can we beli eve In everything we see? A key for success of these shows is the gangrene of the actors. Like American Idol or many others, because the venire criticizes them In a derogative way so the contestants leave the stage but being teased. The audience assimilates this as a normal process so if they dont have skills they begin to feel shame of it or scared to people who can watch them doing things. Another negative thing is that they can think that humiliation is a necessary step to succeed, thing that is not true.We hooked not allow ourselves to be influenced by these shows and that Is why there are recommendations while watching them, such as It Is not recommended for children and young people, thereof they can understand and analyze the background and have a very strong personality. All in all we must be alert and aware to see a reality show, because this can aim to unexpected and negative changes. The best one can do is to turn this experience into something good and come how to s elect those programs that teach us and help us develop.

Olaudah Equiano’s the Interesting Narrative Essay

Olaudah Equianos The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African, Written by Himself, is the story of the eponymous real- manners character, Olaudah Equiano, his life, trials, tribulations and jaunt from slavery at an early age to freedom. For Equiano, it seems that slavery is approximately a metaphysical phenomenon.His entire life is essentially characterized by the different experiences relating slavery, from Africa to the Middle Passage to plantation life in the West Indies and United States. Equianos views on slavery are tough to articulate and very complex. Throughout the impudent he makes reference to different degrees of slavery, at times condemning the practice, and at stark naked(prenominal) times contradicting himself and seemingly lauding it. I believe that his conflicting views are products of his first gear hand experience with or so all aspects of the practice, and near the end of the novel it is clear that he is in favor of ending slavery. put one crossways to a greater extent what is a narrative essayAlthough he was kidnapped at the age of eleven, Equianos familiarity with slavery actually begins long before that. Born in a region that is today known as Nigeria. His male parent a chief, (and ironically himself would eventually reach the resembling status if not for his kidnapping years later), Equianos family was considered upper-class, and thus owned their own number of slaves. I believe that this is the blood line and serves as the basis of which he compares the slavery he experiences later in his lifetime to, and also what may serve as the beginning of his conflicting emotion towards the practice in general.He makes tonicity that slaves in this community, while under the commissioning of a master and with clear distinction of a lesser importance, are still treated in a humane way. On his own account, these slaves do a comparable amount of work to that of new(prenominal)(a) members of t he community. When put into perspective, with no knowledge of whats to come (in regards to subsequent experiences in different aspects and degrees of slavery) at this develop principal it is easy to see why Equiano has not yet condemned the idea or practice of slavery.Shortly thereafter, Equiano is kidnapped (along with his sister, though the two are eventually separated), He narrates being taken on a long, arduous travel through a variety of African regions, during which he had often changed masters. He is first sold across Africa, first to a chieftain, and shortly after to a widow. After which, he is ultimately sold to the possessor of a ship destined for the West Indies.Equiano dubs this Atlantic voyage himself The Middle Passage, and this is where I believe his journey truly begins. Equiano elaborates on his introduction and subsequent alienation to the European culture and their treatment of slaves. He detail the substandard living conditions and destitution of living aboa rd the slave ship, and being a stark line of merchandise to the concept of slavery he knew back in Africa, I believe this is the defining moment where his stand regarding slavery is partitioned.I think its important to note that when Equiano is enslaved by fellow Africans, he makes note of the strong contrasts and class distinctions between himself and them. He makes direct comparisons between himself and the class he hails from, and these other Africans, passing play as far as to call them barbaric and uncivilized. I believe that this is worth noting, because its almost paradoxical how he is very quick to condemn these people and their form of slavery, while at the same time not criticizing the slavery that took place in his own village when he was a child. though not yet acknowledging it, I believe that this is when he begins to form his own tiers of the practice of slavery.After arriving at the West Indies and experiencing the sale of slaves firsthand, Equiano continues along with the slave ship to North America, and ultimately purchased by a oceanic captain, Michael Pascal to work in Virginia. Again he is subjected to cruel treatment inside the slaveholders homes. This is, I believe, the act floor that eventually leads to Equianos final resolution. He details being shocked and hurt to the point where he tries to wash the color of his skin off his face. While travelling the seas with Pascal, Equiano has many more encounters in and with Britain. With more and more exposure to Christianity and European culture, he details that he was no longer panic-struck and apprehensive towards it, beginning to show confluence of African and European cultures. He was eventually sent to school in Britain, educated and shortly after, baptized.It is worth noting that later in the novel he often relates his new religious standpoint to his enslavement. While becoming a Christian himself, whether or not he holds accountable God, himself, or the hypocritical Christian Eur opeans for his enslavement is left ambiguous. Ultimately, (and after brief stints of being purchased by other masters) Equiano is sold to Robert queen regnant. Educated and under the direction of a master treating him relatively fair, Equiano here observes another look of slavery. He is further educated and directed along the path of Christianity, which I believe further adds more conflicting emotion, due to it being comparable to his original notion of slavery from his childhood.While working for King on shipping routes, he determines himself to save some money on the side, in order to deal his freedom from King. Interesting to note though, in the novel he explicitly states that he would like to getting even to Old England, not Africa. While I think this is further evidence of his confluence of English and African cultures, I believe that this is also the beginning of his plea against the practice of slavery, as later in the novel we find out that he does indeed buy his freedom, and much later returns to London and become complicated in the abolitionist movement.In conclusion, it is clear to see that in the mind of Equiano, slavery is not wide-eyed a one-sided condemnation. From birth until freedom, he has lived and experience all aspects of slavery, from his family owning slaves to being purchased himself. Its an interesting and remarkable point of view that few (if any more) people who were involved in the practice of slavery experienced themselves.In the end, I think it is clear to the reader that Equiano is against the notion of slavery, but I believe thats a conclusion he came to because of personal experience along with education and indulgement of European culture. While I dont believe he accepts the practice of slavery, I believe that he accepts slavery as part of how he defines of himself, almost as if slavery could not be abolished were it not conceived in the first place.

Alexander Pope’s “The Rape of the Lock” Essay

18th-century high society through exaggeration and parody. Basing his poem on an actual incident that occurred among some of his acquaintances, pope intended his yarn to put the episode into humorous location and encourage his friends to laugh at their own actions.A mock larger-than-life is a poem traffic with petty subject matter in the exalted style of the great literary epics. This genre is a form of parody for satirical purposes. The poem uses the small-minded story of the stolen lock of hair as a vehicle for making judg workforcets on society and on men and women in general. Characteristics of the ILLIAD and the ODYSSEY that the Rape of the Lock mocks complicate the statement of the theme, invocation of the muse, description of the great battles, supernatural beings taking part in the affairs of men and the hero becoming immortalized in a star or constellation (Long, Pope 1).In the fountain lines What dire offense from amorous causes springs, / What almighty contests rise from trivial things (Canto I, lines 1-2), Pope states the theme of the poem that trivial matters should remain just that- trivial. In the lines following theinvocation of an unlikely muse is clearly stated I sing- This Verse to Caryll, Muse Is due (Canto 1, 3).The entire poem is divided into five cantos and is written in heroic meter couplet verse. The use of the heroic couplet is typically neoclassic because it exhibits the ideals of the time. In order to write a heroic couplet the author must have complete control over his words and the story he wants to tell. A strong sense of order is needed so that the couplets may rhyme and virtually importantly make sense to the reader at the same time. The heroic couplet perfectly accents the epic devices used in the poem, for, as a form of verse the heroic couplet seems to have a connotation oflarger-than-life-situations in the minds of its readers. By using this style in describing such insignificant matters in his poem, Pope only suppo rts his theme that his society places great importance on minor matters.Popes enlarge portrayal of events in Canto I furthers comparison with the literary epic it parodies the traditional epic passage describing the shields of antiquated warriors. Belindas make-up routine is compared to the putting on of armor From each she nicely culls with curious toil,/ And decks the goddess with the shine spoil (Canto II, 131-132). Make-up, clothing, jewelry and other material possessions are this parodys substitutes for armor and weapons. Pope closely imitates the epic form for comic effect in order to expose the questionable values of his time. victimization a vast force to lift a feather (Long,Pope n.p.), thoroughly describes Popes reasons for his use of elaborate language.He uses the epics exaggeration to mock misplaced priorities. The great battles of the literary epic are transformed into card games and flirtatious charades. The great Greek and Roman gods are born-again into an army o f protective but powerlesssprites called sylphs who protect both the serious and the trivial. For all of her conflict This Lock, the Muse shall consecrate to Fame, / And midst the Stars inscribe Belindas name (Canto V, lines 149-150). Belinda is immortalized in the sky by a star bearing her name.Satire is a glass wherein beholders do generally discover everybodys nerve but their own (Long, Racine 4). Pope uses every aspect of the mock epic to satirize the frivolity of the bulk around him. He takes specific scenes and uses parody to illustrate the insignificance of everyday rituals. He even uses the structure of rime couplets to juxtapose the ordinary with the extraordinary to reveal the societys distorted value system.

Pros and/or Cons of Stand Your Ground Law Essay

The infamous George Zimmerman case has stirred the controversy around digest Your end laws and brought these laws to the human race light, becoming the subject of vigorous nationwide debates whether these laws should be repealed or not. Like many controversial legislative, standstill Your commonwealth laws have their critics and proponents, and both sides tend to make valid points in defense of their position. The goal of this make-up is to show cons and pros of Stand Your aim laws. In Florida as well as 21 some other American states, as stated by to the National Conference of State Legislatures, the above-mentioned laws are self-protection laws that save individuals of their duty to retreat from an attacker before using force against them anywhere they are legally allowed to be (Clark).While in general these laws do not economic consumption such a notion as stand your ground specifically, Florida together with nine other states has these words in its law. In Stand Your Gro und law in Florida, particularly, it is stated that a person who is not engaged in an unlawful natural action and who is attacked in any other place where he or she has a right to be has no duty to retreat and has the right to stand his or her ground and meet force with force, including deadly force, if he or she reasonably believes it is necessary to do so to prevent death or great visible harm to himself or herself or another or to prevent the commission of a forcible felony (qtd. in Clark).The major con of this law, as its critics think, is that it essentially gives individuals with malicious intent a legal loophole to avoid lamentable prosecution for killing someone if these individual state that they had to defend themselves. Eric Holder, the US Attorney General, is among those opponents of Stand Your Ground laws who believe that these laws leave allow individuals to provoke others to attack them first and then, as it can be deemed self-defense and these individuals will not have the duty to retreat, they will be able to kill them without fear of get prosecuted (Cooke). In states with Stand Your Ground laws, spate will not have to think twice whether they should use weapons to defend themselves against the attackers or retreat because they will have the right to kill their attackers. Such violence will breed further violence.Criminals may use this law to cover up the deliberate and premeditated killing of people. However, proponents of this law may respond to the above-mentioned claims of their counterparts as follows. Thiscritique of Stand Your Ground crumbles under the tilt of the argument that In almost every state, if and when an individual enters into an altercation with the deliberate intention of provoking the other party into threatening him with death or injury, they lose the right to claim that they were acting in self-defense (Cooke).All individuals have the right to liberty and life and therefore, they have the right to defend themsel ves. Those who attack people violate their victims rights to live, so Stand Your Ground laws legally recognize these rights, attempting to tilt the balance in privilege of the attacked (Cooke). Both, the opponents and proponents of Stand Your Ground laws have reasonable and sound arguments, but they need to find some fondness ground regarding these laws that will satisfy both sides.Works CitedClark, Korey.

In this review, contemporary literature has been reviewed to update current knowledge on this topic. This assigning reveals that radionuclide imaging is an important diagnostic modality in the workup of hyperthyroid disorders, but despite that, in some cases the diagnostic yield is better with ultrasonography or PET scanning. In some cases, combined use of these imaging investigations pinpoints the diagnosis in a more suitable manner. Review of these articles and the knowledge apparent may be used to frame a guideline of advice regarding imaging practice in this area.The thyroid gland produces both hormones, namely, thyroxin (T4) and triiodothyronine (T3). The se are known to play important physiological roles in the human body. Anatomically, the thyroid gland is located in the neck, in front of the trachea. It comprises of two lobes, right and left, connected by a narrow bridge of thyroid tissue, known as isthmus. It is a very highly vascular organ. The mean(prenominal) adult thyroid gland consists of follicles lined by thyroid follicular cells that contain large total of thyroglobulin. This serves as the protein precursor of the thyroid hormones (Broome, 2006). Endocrinologically, increased need for thyroid hormone leads to a signal driveway mediated by thyroid stimulating hormone ( thyroid-stimulating hormone) leading to release of active hormone from a bound state with thyroglobulin to a free state, eventually being secreted into the blood stream. When there is hypersecretion of thyroid hormones payable to any cause, the condition is known as hyperthyroidism. Usually hyperthyroidism is indicated by an elevated level of TSH. Theref ore, in clinical practice the diagnosis of hyperthyroidism is made by finding an abnormally elevated TSH level which
