PCR and Southern Blotting: Applications in Medicine

PCR and Southern Blotting Applications in MedicineIntroductionThe 1970s introduced an inspirational technique in which a specific sequence could be determined from a sample of desoxyribonucleic acid via the process of Southern blotting. This method, named after Edwin Southern, provided the basis for a undulate of common laboratory techniques such as western blotting, eastern blotting and northern blotting 1.Shortly after, in 1983, a revolutionary method was invented by Kary Mullis, called the polymerase chain reply (PCR) 2. This procedure was skipperly use to amplify and identify desoxyribonucleic acid sequences in the human genome. Its use in factortic analysis was immediately recognised, as unitary of the first publications of its use was of prenatal diagnosis of sickle-cell anaemia 3. Since then it has been manipulated and a whole array of techniques have been derived from this invention.Both PCR and Southern blotting have been used wide in understanding and identifying micr obes which in turn assists the diagnosis and management of patients suffering from infectious diseases.PCR ProcedureThe sample of DNA is heated up to 90C to separate the two strands of DNA thereby exposing the nucleotide bases on each strand. A primer is then annealed to each strand from the 5 region at around 60C and the temperature is increased once more. The thermostable DNA polymerase enzyme, Taq, prevents contamination by binding free complementary base pairs to the original strand of DNA at temperatures up to 70C. The strands are then cooled and double the amount of DNA is synthesised, and the cycle restarts until a sufficient amount of DNA is produced.Reverse-transcriptase PCR (RT-PCR) is used when the original sample of RNA is transcribed so that DNA is the product of amplification. The sensitivity of PCR is great, as invention is from a single nucleotide base whilst its quantitative qualification is derived from the proportional expansion of amplified DNA from its origina l size 5.Southern Blot ProcedureSouthern blotting begins with a sample of DNA which is first broken up by a restriction endonuclease into smaller, varying fragments. The DNA is then placed into wells to undergo agarose gel electrophoresis where the fragments diffuse across a polarised eye socket according to their size. The DNA is denatured by sodium hydroxide and transferred to a sheet of nitrocellulose or nylon and incubated with a hybridisation investigate of single-stranded DNA. This radiolabelled probe binds to the exposed complementary base pairs and can be detected by autoradiography 6.Southern Blotting Applications in Medical MicrobiologySouthern blotting is primarily used for DNA fingerprinting, gene sequencing and genetic engineering.It has been used in the identification of demarcations in microbes such as concluding the type of human papillomavirus extracted from a condyloma. However in this case it provided to be unreliable as it produced false-negatives, as PCR and in-situ hybridisation were deemed to be more efficient 7. Another use of Southern blotting was in the sleuthing of a strain of Listeria monocytogenes. In this study it was deemed an important technique in verifying species identification and in the characterisation of epidemic strains 8.This method can be used to DNA fingerprint most microbes and determine a diagnosis and treatment for a patient suffering from their pathogenicity. However it is found to be too laborious, time overwhelming and requires large amounts of high quality DNA for most routine laboratories yet variations of this technique are still widely performed. The western blot, which uses antibodies as the probe to detect proteins instead of DNA, is a confirmatory test in the diagnosis of a human immune-deficiency virus(HIV) contagious disease 9. Since the established use of PCR there has become a decrease need for these laborious techniques in DNA sequencing 10.PCR Applications in Medical MicrobiologyPCR can be use d in detecting the genetic sequence of all microbes. It is effective in detecting organisms in early cultures where organisms are otherwise difficult to isolate, for example in enteroviruses RT-PCR is more sensitive than culture and the gold standard is detection of the this genome in cerebral spinal fluid (CSF) by PCR 11.PCR is also used in detecting genes encoding antibiotic resistance such as in Helicobacter pylori and Methicillin-resistant Staphylococcus aureus. However its use is currently unsuitable for the diagnosis of H. pylori as clinical samples may contain inhibitors which can generate false-negatives10.PCR is used in quantifying the viral load of HIV within an infected person therefore determining the effectiveness of their treatment. The problem occurs when the genome sequence of the HIV changes therefore the PCR method needs to be altered and the current test would prove useless9. Currently immunoassays are used in the diagnosis of a HIV infection, however early in in fection there is a variable period of time until anti-HIV antibodies can be detected and this provides a potential area of identification of the HIV by PCR 12.Pitfalls of PCR involve that the sample must be kept cold during storage and transport to the laboratory, the expertise required for analysing and interpreting results as well as standardising between divers(prenominal) laboratories and finally the expensive cost of the procedure compared to available techniques9.ConclusionThe applications for PCR and Southern blotting are enormous however they have limitations which prevent it from being routinely used in the diagnostic laboratory. With the advance of technology both are being developed, especially PCR, and have endless applications in medical microbiology.

Administrate Procedure within the Childcare Settings

Administrate Procedure within the Childc be SettingsThere atomic number 18 8 principals principles of the Data Protection Act 1998 these dejection range from right of personal data to personal data being graceful in consonance with the rights of data protection act. This question will look at four of the main principals.personal data shall be stainless and, where necessary, kept up to involution.( This twenty-five percent principal of the data protection act is about keeping up to date with personal nurture and the accuracy of it. When implementing this principal into everyday business it is not always the easiest affaire to do. However this principal of the act would help employers to help employer to store information as accurately as possible. When adopting this principal within a electric shaver care setting accuracy plays a banging part for example, much of the information recorded by the minor care provider whitethorn be required by HMRC to claim benefits for sma ll fryren in their care by parents. This information is needed by the parent in order for them to provide information to receive the correct amount of benefits. HMRC will calculate how much money can be provided to assist parent to receive care for their children. Not yet is this information beneficial to parents but is beneficial for the child care provider this will help them to calculate business tax. If the child care provider is ego employed and is working on a private basis, this information would be useful to complete self assessment tax return. Child minders, are support to complete accounts which detail every financial transaction that is made. Good point. Accuracy is also important to ensure the children are kept safe.Personal data processed for any settle or purposes shall not be kept for greater than is necessary for that purpose or those purpose. (This principle contains comm whole asked guidance as to how long data should be kept for before it is destroyed. The ac t is not specific about the length of time data should be held for, but gives guidance on good practice so that organisations are better informed to write their experience policies. A child care setting must be sensible of this principal and comply by making sure that records are kept only for its purpose and no longer than deemed.Personal data shall be obtained only for one or more specified and lawful purposes, and shall not be further processed in any manner incompatible with that purpose or those purposes.( A child care provider should be specific about the reasons fir requiring the information to be gathered, and what they are going to use it for. If, after order of battle the data, it is decided to use the information for another purposes, consideration, should, be given as to whether this is fair to the single(a). if you wish to use data for an additional purpose, further consents should be obtaining from the individual and seizely held.Personal data shall be adequate, relevant and not excessive in relation to the purposes or purposes for which they are processed.( Childcare providers must ensure that they aid this principal by ensuring that all data stored on individual i.e. staff, parents, children is relevant to serve its purpose. For example the provider should not hold information on individuals where not deemed necessary for business or other purposes.Evaluate the need for accurate, readable and up to date record keeping, and indentify the consequences for non-compliance.An integral part of a successful child care setting is its administration department. Administration and records should be kept in a logical and protected manner and should be clear and formatted and easy to understand. In regards to a child care setting there will be several different types of information which will be needed and stored. The main purpose of the child care provision is the safe guarding of children. Sometimes this information would need to be accessed by o utside agencies. As mentioned above accuracy plays a big part in the data protection act and also in the running of a successful child care setting. Not only does accurate information help parents to provide information to HMRC to receive benefits but also, to aid the business in tax and other financial responsibilities. if this information was not accurate and precise parents claiming benefits could receive the wrong amount of money to receive childcare and also the business could be affected by wrong taxable income. wellness and safety records must also be accurate and precise when considering a child care environment. For example the listing of medical specialty and allergies of children is integral if this information is mighty and accurately documented staff and other members would be aware of the Childs need. The correct dosage of medication would be administered and allergies to certain products could be rescinded. If this information was incorrect and not documented child ren could fall ill and be put in a medical dangerous position. All special requirements regarding children should be adhered to at all levels avoiding mistakes and inaccuracy.legible records are essential from a safety perspective. Scruffy or illegible writing is dangerous, particularly if the information is written on a medical or child information record, and is not clear. Legibility is also important from a financial perspective, to ensure that correct information is submitted to the HMRC for tax purposes. In a child care setting where there is more than one worker or staff member it is vital that all recorded information is legible and accurate. This is to avoid mistakes and ensure that children information is documented in a clear manner, for example child journals and where food and medication are documented. If this information was not legible it would join on the risk of safety of children being breached and could result in accidents such as a child receiving a double dosag e of medication.There are some(prenominal) oecumenical rules of some that should be considered concerning legible informationWhere possible, Information should be recorded in black ink. It is considered that black ink is more legible, and is clearer to read if it is photocopied. hired man should be legible.Changes to documentation, such as the child medication form, should be signed and dated.it is good practice not to use white correction fluid when amending records as they should be transparent according to the Data Protection Act, and not covered up with a physical barrier. Mistakes should be crossed through with a path so that they still.Up-to-date information is particularly important with regard to medication changes, food requirements and particular needs that a child may have. Having up to date contact information is highly important, for example if in case of an emergency of a child not being able to contact parents due to mobile numbers being not in use is the worst ca se scenario.Explain the different ways of recording digital and paper records in the child care setting. Digital data can be a very unpredictable way of storing data as computers are unpredictable. Adequate methods should be select when exploitation digital record keeping this is to ensure in case of computer malfunction digital records could be safe guarded to ensure that filed can be retrieved from the system. There are several methods available for doing this.Save on to portable hard driveBacking up data on a regular basisAll portable hard drives should be stored safely and securelyThe data is stored on the computer should be protected by a password. When you switch a computer on, the settings allow a desktop password to be employed. This should be used so that if the laptop is ever stolen, the data contained within it will be safe.If the use of desktops is permitted for children within the childcare setting it is beneficial to have a separate pc which allows them to do this se parate from pc keeping records and personal information. This prohibits children from accessing personal data or information which is private and mystic and reducing the risk of deleting files and records. This simple rule will also ensure confidential to data stored in the PC.Paper records in some respects require a different type of storage to digital media. Paper records are general more accessible and so should be stored safely and securely depending of the type of information that is recorded. For example records which contain information regarding a child&aposs medication or special requirements should be easily accessible. However such information regarding financial information of staff payments etc should be stored in a locked cupboard. Where paper records are concerned safe storage should be considered especially to avoided and damp area as this would destroy the information recorded and stored. If keeping paper records as distant to digital records the child care provi der should consider storing records and documentation in a lock filing footlocker. this will ensure that they are in their own dedicated area and having an added security feature. If working in a home child cares getting it would be advantageous to purchase a filing cabinet which would resemble furniture.There are two main types of primary data storage, one being digital and the other being paper. There are umpteen ways in which digital records can be stored and secured such asLaptopsUSBPortable Hard drivesPDAMobile PhonesAll these devices can be a useful tool to store information in a business child care setting. However many of these if not all are allergic to theft. Many of these devices can be password locked which is a useful tool as it prevents people who should not have access from accessing personal data, Records and files which are stored using a digital format could be backed up and secured within the device and multiple storage devices could be obtained. With the sue o f password and pin this acts a good security feature. However paper records would not have the same benefits.Storing of paper records could be bulky and unsecure if not locked away in a secure filing cabinet or cupboard, data could be easily accessible. Not only is the security of paper records not as efficient as digital records but also be inefficient in backing up. For example with a digital device a small USB stick would hold many record and files, however, if multiple copies of records are needed when using paper format this would result in many pages needing large amount of storage space. Another thing to consider regarding paper records is damage/ Paper records could easily be destroyed in fires and water damage, which would result in a lot of work in order to retrieve the files. Whereas if you using a digital method of storage this could be easily done with minimum destruction and effort. If working in a child care setting this is useful to record and maintain a file and per sonal data in a digital format. This would be easier, more secure and easy to back up.

Martin Luther King, Jr.’s “Letter From Birmingham City Jail” Essay

Martin Luther faggot, Jr. wrote an argumentative persuasive essay, the Letter from Birmingham Jail on April 16, 1963. top executive had written this letter to insure and move to the criticism made by the white clergymen. The letter was an approach to end racism and hatred in a non-violent manner. The non-violent movement was organized by King and his pro- down(p) organization called The Southern Christian Leadership Conference. King and his pro- down in the mouth organization base presented the essay to argue non-violent actions against the racial discrimination and hatred among the black confederacy residing in Birmingham. The letter was also aimed towards the liberty and equality to not just the black community but also to the white community, to the social, religious and political community. King wanted to address the stress of everyone having freedom and equality. Kings main thesis in writing the Birmingham Letter is that racial discrimination and hatred to the black com munity is due to the optimism of the white community. I agree with his main points that King had presented in the essay. Everyone should have equal rights in every criteria including socially, politically, and religiously. This is what King wanted for everyone. He wanted to peacefully bring every race and gender together as one society not multiple societies like how it was. King argued the freedom and equality for everyone in the United States and that there shouldnt be a reason to prejudice to each other. King supported his points throughout his essay by using logos. Logos is the use of facts, statistics and studies to show others why and how your point is correct. He researched his opinions and accumulated facts to prove his opinions and thoughts. In the l... ...n you advocate breaking some laws and obeying others? The answer lies in the fact that there are two types of laws just and unjust. He makes the readers think that he knows what he is talking about and shows determina tion. King had written this letter to address and respond to the criticism made by the white clergymen.

Comparing Composed Upon Westminster Bridge by William Wordsworth and Lo

Comparison between William Blake and William Wordsworths Views of London William Blake grew up in the slums of London and this is shown in his poem, he wrote his poem in the slums and covering alleys of London as he never had very much money. He describes London as being charterd, this gives us the impression that every subject has rules and boundaries in London, and that there is no mystery to be discovered. Also chartered means on a map, almost as if it is owned, by the king perhaps. The line in which the word is on, I wander through each charterd street, near where the charterd Thames does flow, makes us feel as if every thing is owned and nothing is natural, like all the people in London are prisoners of society The ending line of stanza two tells us, The mind-forgd manacles I hear, this is Blakes way of showing to us that there are no free minds in London. Everyone had been brainwashed by society and they could not think for themselves because of that. In the neighboring stanz a Blake describes the corruption of the Church of England by mentioning, Every blackning Church apalls this shows the dirtiness of the buildings and shows us that there is a possibility that he is a strong catholic. This line ties in very well with the line directly above it How the chimney-sweepers cry, both of the lines are discussing how dirty and filthy London is. We could also think of these lines in a different way Blake could be telling us that the priests are corrupt and dirty rather than just physically dirty. In the final line of this stanza, Blake states. And the unfortunate soldiers sigh, runs in blood down palace-walls. This could be considered as another sign of corruption, and that monarchs are to blame for the death in London a... ...f London, but they only do this because of their life before they wrote the poems. One poet grew up in the rich area outside London and moved there later, whereas the other poet grew up in the slums of London. They never had the chance to see London through each others eyes, if they had they may have thought differently of London. Both poets grew up and wrote about what each thought of the same(p) place, London is a city that is superb and beautiful to the people who know it like that. Whereas it is filthy and dirty to the people who have grown up in those filthy dirty areas. In my opinion London is a place that is somewhere between these two extreme versions of it, a place where there is magnificent splendour but also a place where there is filth and poverty. Theses poems where written two hundred and six years ago and London has not changed that much since then.

Fahrenheit 451 as a Criticism of Censorship Essay -- Fahrenheit 451 Es

Fahrenheit(postnominal) 451 as a Criticism of Censorship quill Bradbury criticizes the censorship of the early 1950s by displaying these same themes in a futuristic dystopia novel called Fahrenheit 451. In the early 1950s Ray Bradbury writes this novel as an extended version of The Fireman, a short story which first appears in Galaxy magazine. He tries to show the readers how terrible censorship and mindless conformity is by writing about this in his novel. In Fahrenheit 451, Bradbury uses artificial stimulus, such as television and radio, to provide the reader with a feeling of how isolated the public is and how their minds are be controlled by this conformist government in the twenty-first century. He uses technology, like the Mechanical Hound and also drugs, to show the oppressiveness of the government in his novel. Ray Bradbury chooses to write this book after seeing many of his fellow writers and other entertainers being blacklisted by Senator Joseph McCarthy in the early 1950s. While he couldnt just openly oppose this behavior, for he would surely be illegalise, Bradbury writes about an exaggerated version of his own government in which books are burned along with the houses that harbors them. This is to demonstrate to the readers how let the government censor their art could lead to more drastic measures. Such as editing one line in a book thus a page then the whole book is condemned and burned along side the many other books and ideas that do not agree with the government. This then leads to the ultimate condemnation of all books and forms of entertainment, which is not politically correct and/or agreeable to the governments ideas. Bradbury uses artificial stimulus... ...writers, and other entertainers were blacklisted by McCarthy and some were even brought to trial under perplexity of being Communist. In conclusion, Bradburys criticism of the 1950s censorship and conformity opened the eyes of the public to the wron g-doings of the government at the time. Many people began to realize that they were being censored for almost everything and art, for example in the form of writing and film, was being simplified to almost nothing.

Childe and Anthropology :: essays research papers

Essay Questions1. Childe equated civilization with urbanism. Other social scientists, while admitting a considerable overlap, distinguished between the cultural phenomena characteristic of urban areas and those of "civilized" societies. Childe identified 10 formal criteria that, according to his system, indicate the arrival of urban civilization. These are increased settlement size, concentration of wealth, large-scale public works, writing, representational art, knowledge of exact sciences, foreign trade, full-time specialists in non-subsistence activities, class-stratified society, and political organization based on residence rather than kinship. He saw the underlying causes of the urban revolution as the cumulative growth of technology and the increasing availability of food surpluses as capital. Further archaeological evidence demonstrated that the formal criteria Childe proposed were, in reality, not universal. A core of basic structural trends, however, appeared to be essential as cities appeared in different areas at different times. Some of the problems that may arise with any given set of criteria(s) for defining civilization and the process in which they develop untruth within things such as time frame, area, mental capacity of the peoples of the society, and material advancement. In reference to ancient Mesopotamia and Egypt, Childes criteria apply somewhat directly. This is said because some(prenominal) of these societies had some forms of sciences (i.e. mummification/Egypt), wealth or caste system, and a public works for buildings and city-states. Their only difference lies in that in ancient Egypt, the politics were equilibrise by kinship rather than residence.2.     Archaeological excavations in Mesopotamia, conducted since about 1840, have revealed evidence of settlement back to about 10,000 BC. Favorable geographic circumstances allowed the peoples of Mesopotamia to take to the woods from a hunter-gatherer cult ure to a culture based on husbandry, agriculture, and permanent settlements. Trade with other regions, tribes, and chiefdoms also flourished, as indicated by the presence in earlier burial sites of metals and precious stones not locally available.
