5 Ways to Jumpstart Your Career in the New Year

5 Ways to Jumpstart Your Career in the New Year It’s a new year. This is the time when everybody takes stock of where they are in their life and career, which means a shockingly high percentage of American workers will decide to look for a new job this month. But†¦maybe we don’t need to be so hasty. It could be that your job is not the problem, there are just a few more things you could be doing to further your progress in your career. Try these five things before making any drastic changes. Who knows, you might realize you’re happier than you thought right where you are.1. Have coffee with your bossRather than wait for an annual appraisal, find time to grab a quick and casual cup of coffee with your manager or supervisor, or even the big boss- if appropriate- from time to time. You’ll express your keenness to develop and succeed, and get a better sense of what you could be doing to improve and grow. Plus you’ll be on the radar as someone sharp and hungry to move up the ladder, which no doub t will be remembered come review time.2. Stay in the familyMost companies prefer to promote from within. So why not keep an eye on positions up the ladder, or even in different departments, that might be suitable for you? If you’re not feeling challenged or rewarded enough, you can always approach your manager or HR rep about possibilities for moving within the company to a more mutually beneficial position.3. Ask about  trainingMost companies have programs for training their employees in new skills and software. If your current job isn’t giving you enough room to develop, why not ask your manager or supervisor if there are any training opportunities they could consider you for? It’s a win-win situation for you both. They get a better trained, more qualified employee; you get free education that will serve you throughout your whole career.4. Get mentoredDon’t just suck up to your boss. Find someone in the company whom you admire and ask if they might me ntor you. They’ll probably be flattered, and you’ll learn valuable things that can help you grow professionally, or even give you a boost up to the next rung of the ladder.5. Remain positiveSuccess begets success. If you want more recognition for the good work you are doing, consider noticing the good work of your co-workers and congratulating them on a job well done. At very least, you’ll build a positive, success-inducing work environment. At best, they will return the favor. Everybody wins.

The Rape and Murder of Sarah Goode

The Rape and Murder of Sarah Goode In the summer of 2014, petite, 21-year-old Long Island mother and medical technician Sarah P. Goode disappeared. Her partially decomposed body was found in a wooded area about a week later. The resulting autopsy and criminal investigation revealed Goode had been brutally raped and stabbed to death by a man whose sexual advances she had earlier rejected at a party.   Search for the Missing Mom On June 8, 2014, Goodes family called Suffolk County police Sunday to report her missing. She had not been seen for two days. The family began passing out fliers and neighbors pitched in to search. The next day, Goodes gray 1999 BMW was found parked in a wooded area in Medford, not far from the home Goode shared with her mother and 4-year-old daughter. Although the car had not been broken into, police said it was found under suspicious circumstances. Suffolk County Detective Michael Fitzharris would not comment on those circumstances, nor did he reveal whether or not Goodes personal belongings had been found in the car. This is a 21-year-old gainfully employed Long Island girl. Everyone has to have their vehicle out here, Fitzharris told reporters. For her family to not see her for a few days †¦ we take that very seriously. It was later learned that police had discovered clumps of hair and blood inside the vehicle. Using K-9 units, police swept the wooded area where Goodes car had been found. On June 12, 2014, almost a week after shed vanished, a group of searchers found her body in the woods within a mile of the site where  her  abandoned car had turned up the day after shed been reported missing.   Killer Charged   On July 12, 2014, Dante Taylor, a 19-year-old former Marine from Mastic, Long Island, whose advances Goode rejected at a party theyd both attended was arrested in connection with her murder. A bloody handprint in Goodes car and text messages between him and Goode on the night she went missing linked Taylor to the murder. Taylor was arrested but later released after it was learned that police had taken fingerprints, DNA, and cellphone evidence without probable cause and had questioned him without reading him his rights. He was arrested again a month later on unrelated charges in Vero Beach, Florida, and extradited for trial. Taylor was arraigned on murder charges in a Central Islip courtroom. As prosecutor Janet Albertson described the events surrounding Goodes death, about 50 of her family members were present in court, some responding to the horrific details in vocal anguish, others in verbal taunts. Goodes brother-in-law was removed from the courtroom. Albertson described the gory scene police found inside of Goodes blood-soaked car. She went on to present evidence that Taylor had brutally raped Goode and had subsequently beaten her so badly with a sharp metal object that a piece of metal had been found embedded in her skull. Goode had been stabbed more than 40 times. After she was dead, Taylor dumped Goodes body, nude from the waist down, in the woods. Police and Prosecutorial Misconduct Tarnish Conviction During the trial, the prosecution was sanctioned by state Supreme Court Justice John Collins for withholding evidence from the defense that included a series of Crime Stoppers tips pointing to other potential suspects. It was also learned that police destroyed a threatening message from a boyfriend with whom Goode had recently split up. Nevertheless, Taylor was found guilty of first- and second-degree murder, and attempted rape in the first degree in the death of Sarah Goode and sentenced to life in prison without the possibility of parole. Convicted Killer Dies in Prison On October 2017, the 22-year-old convicted killer was found dead at the Wende Correctional Facility near Buffalo, New York, where he was serving his life sentence. Goodes family responded to the news with a Facebook post, which read:   â€Å"The monster who so violently ended Sarah’s young life will no longer breathe another breath, will no longer see another day, will no longer have the privilege of living a life- something he made certain she could not do. Sarah’s beauty is eternal. Her laugh is unforgettable. Her memories are carved in the hearts of all whom she met.† However, Taylors trial attorney, John Lewis Jr., insisted that his clients conviction was a travesty and a perversion of justice, stating: â€Å"It’s a tragedy. His death is just another injustice in a string of injustices. I just hope someone is held accountable for his death. Now Suffolk County will not be held accountable for the injustices it committed in getting his conviction.† Sources Landau, Joel.

Summary of the vice president debate Essay Example | Topics and Well Written Essays - 500 words

Summary of the vice president debate - Essay Example He specifically mentioned about the killing of US ambassador in Libya. However, it was Bidden who assertively maneuvered the debate from one issue to another and also started a debate on foreign policy. During the debate it was quite clear that Bidden, due to his experience in Politics, was more mature and assertive in debating on certain issues. Though on economic issues, Ryan was able to highlight some of the weaknesses of the government however, he was clearly not been able to put in a full-fledged attack on Bidden regarding the overall economic performance of Obama regime. Bidden’s arguments for doing much more for the Middle Class of America, tax policies, Medicare and other issues have actually not allowed Ryan to plan a full-fledged attack on the overall policies of Obama government. Ryan also did not seem to be prepared much on the issues of taxes and was pressured by Bidden to go into details which he unfortunately was not able to and thus was clearly lacking a well thought out debate plan. Bidden was also specific about the issues on the Military and presented facts and figures which Ryan was not able to provide for. Bidden’s ability to actually dominate the debate and suggestion of increasing the military budget was something for which Ryan looked less prepared. Debate also touched upon the issue of Middle East and Bidden was able to put forward the arguments of having better relationships with Israel. Ryan actually attempted to suggest that relationships between Israel and US were deteriorating however, Bidden was convincing enough to actually highlight that the relationships between two countries have actually improved over the period of time. Bidden was also able to defend Afghan Issue and defended the policy of leaving Afghanistan and handing it over to Afghans with support from US. Ryan was however not been able to fully justify the

Hamlet: The Man behind the Madness Essay -- ophelia, shakespeare

What drives Hamlet to his madness? How does it relate to Ophelia’s madness? Are Hamlet and Ophelia both truly mad? These are some questions that I contemplated as I read Hamlet. The main character, Hamlet feigns madness after learning of his father’s murder; however, he becomes mad later on in the play. Is it possible that Hamlet became so wrapped up in his father’s murder that he was unable to distinguish fantasy from reality? At the beginning of the play, Hamlet has learned that his brother, the newly king, Claudius, murdered his father. In Christian Wertenbaker: What is the riddle in HAMLET? (Sirs.com, 2011) it is stated, â€Å"From then on, Hamlet has to find his own way. He has become a seeker of truth. Unless he verifies the facts for himself, he cannot do the act† (1). This shows that Hamlet can’t back away from what he is meant to do. In his eyes he sees himself as being chosen to avenge his father. In fact, Hamlet proclaims, â€Å"The time is out of joint. O, cursed sprit, That ever I was born to set it right† (I. V. 207-208)! Already Hamlet is stressed out by his misfortune. He sees no other option, but to kill his uncle. After his meeting with the ghost, Hamlet becomes obsessed with death. It is obvious that Hamlet is wrestling with the idea of whether or not he can commit the act. At this point he is capable of reasoning, but prior to this he was wily enough to invent his false madness. He has not lost his ability to discriminate right from wrong; therefore, he is not mad. To be mad a person loses total reasoning. Still he is determined to discover whether or not Claudius did really murder his father. So, Hamlet organizes a play that reveals the truth about his father’s death. This play serves as a strategy to force Claudi... ...f action have been eaten up by thought, he to whom the universe seems infinite, and himself nothing; whose bitterness [75] of soul makes him careless of consequences, and who goes to a play as his best resource is to shove off, to a second remove, the evils of life by a mock representation of them - this is the true Hamlet† (2). To me this means that Hamlet is what the audience or reader makes him to be. He is not mad, but a part of everyone. He is seen in the audience. This play contains a truth, the truth of life. Hamlet’s character contains many feelings that are shared such as sorrow, dread, and lonely. For Hamlet’s character lives through the reader.

Nisa Critique

While there have been many rich descriptions of the life of the !Kung of south central Africa, the account given by Marjorie Shostak in her analysis of the life of a woman of this clan appears to be a fascinating account at best but not entirely scholarly since it flouts major ethnographic guidelines.Introduction:The !Kung people are a tribe of hunter-gatherers who live as bushmen in the   southwestern part of Africa,   in isolated areas of Botswana (where they make up only 3 percent of the population), Angola, and Namibia, deep in the Kalahari desert. After gaining fluency in the language of the! Kung, Shostak returned to Botswana in 1975 for six months to complete the life histories of several women in the tribe.Marjorie Shostak manages to takes us into the oldest culture on earth by living with a hunter/gatherer tribe in southern Africa and manages to give us the details of there way of life through an interview with them, of course, before their way of life was further damage d by careless government administration policies. She reflexively collects interviews and anecdotes that enable her to explain their morals, architecture, tribal politics, spirituality, games, marriage rituals and subsistence lifestyle, giving us one of the best looks at how human society began all those thousands of years ago. Also read: My Problem With Her Anger SummaryOne of its major flaws especially for those with a strong understanding of anthropology is the fact that she concentrates her analysis from the report of one dominant character named NISA [the name is fictitious]. This results in a narrative of an idiosyncratic life, one that, as the !Kung woman Nisa once told Shostak, †I will break open the story and tell you what is there. Then, like the others that have fallen out into the sand, I will finish with it, and the wind will take it away†; seems to imply that each woman’s life is unique and may not reflect the truth about women’s lives in the general community of the !Kung clan, even though it truly attempts to mirror the conventions and culture of the group as well.However, from the book we are able to determine Nisa’s character as a woman who is forthcoming in personality, and unabashed and expressive in her native tongue, although she also comes across as de manding and manipulative in behavior. This presented to Shostak great problems in gaining an objective analysis, a fact that generated early ambivalent feelings towards Nisa which as she reports, did not endear Nisa to her any bit. Although Shostak tried to interview more than a dozen other women of all ages; inviting recall, asking pertinent questions and seeking bio-graphical highlights she seems to finally have settled her choice on Nisa as informant because of her   particularly forceful, colorful language, and generally truthful replies.Secondly, although   the justification of Nisa as informant is reliable, it only serves to foster the concept of authenticity in ethnographic representation. The importance of authenticity in ethnographic representation is still in doubt as portrayed in James Clifford’s   review of Edward Said's Orientalism, Clifford asks, â€Å"Should criticism work to counter sets of culturally produced images like Orientalism with more â€Å"au thentic† or more â€Å"human† representations? Or, if criticism must struggle against the procedures of representation itself, how is it to begin?’The general consensus seems to be that authenticity is itself a representation which can be misused. For example, the purpose of the poet or novelist is creative self-expression. For the creative writer, representation is the vehicle for expression; the creative writer consciously chooses representations as representations. The writer of nonfiction, however, typically focuses on the substance of what she wishes to communicate, and often fails to realize that she uses representations when communicating her ideas hence giving rise to rhetoric. Rhetoric is the characteristic manner by which a text's language and organization convinces its readers of the truth, but is itself not truth.Thirdly is the issue of dialogue versus monologue in ethnographic presentation. It is very apparent that Shostak’s   focus moves aw ay from the central position of the ethnographer (implicit in ethnographic realism and explicit in Dumont’s example of the self-reflexive approach in his book The Headman and I: Ambiguity and Ambivalencein the Fieldworking Experience), and brings the importance of native informants to the foreground. â€Å"The other† is given the opportunity, albeit limited, to represent herself in Shostak's text. Shostak's text is also significant because it attempts to incorporate dialogue as a structural feature.Shostak demonstrates the potential usefulness of multiple voices although her ultimate control over the text makes it a monologue. The monological aspect is repeated within the text itself: there is no true discourse between Shostak's and Nisa's portions of the text, only alternating monologues.   However, according to Stephen A. Tyler this presents a problem in ethnographic presentation, one that is solved in a different approach which he suggest when he says, â€Å"A po st-modern ethnography is a cooperatively evolved text consisting of fragments of discourse intended to evoke in the minds of both reader and writer an emergent fantasy of a possible world of commonsense reality, and thus to provoke an aesthetic integration that will have a therapeutic effect.†Tyler's emphasizes the dialogical nature of ethnography [alternating monologues as is the case in Shostak’s work], were the discourse is between reader and writer rather than between the writer and the culture he studies. Tyler maintains that the experience which matters is not the fieldwork but the writing of the ethnography; the ethnographer does not attempt to represent another culture to the reader, but rather to evoke in the reader a recollection of his own culture. Ethnography is a way to make the familiar unfamiliar and then familiar again.Lastly is the authors choice of topics that evolve around the issue f sex and violence maybe justifiable if viewed from the perspective t hat narrative is highly charged with sex because sex is important in !Kung life. From Shostak’s   very provocative findings, such as a much more sexually egalitarian sensibility than our own, we see that in the !Kung culture, marriages are largely monogamous, with some sanction for a second wife; lovers are accepted for both husbands and wives, but discretion is made more important expressly because discovery can lead to mayhem and even murder. However, Shostak seems to get this information largely from Nisa’s own personal account.Personal accounts are   rarely written without particular motivation. Every account has some agenda. Scholars suggest that we need to always consider why the subject feels it is important to share his or her life either privately or with an anonymous public. This is because the narrator’s motivation will account for what parts of a life are discussed and what details are filtered out. What motivated the author of the personal accou nt?Whether written or oral, a personal account is a subjective, selective account of a life recorded for a specific purpose, ranging from personal catharsis to revisionist history. There are many motivations for the creation of personal accounts, including a focus on the self, on others, or on posterity. In this particular account, were Shostak seems to have solicited the story, rather than finding the account, the scholar’s reason for seeking the personal account will probably color the nature of the questions asked.In this case, the personal account will likely reflect the scholar’s interests more than those of the subject. Hence, it can be postulated that Shostak’s interests in giving Nisa’s account was to highlight the issue of women and not entirely for ethnographic purposes. This can be evidenced by the fact that in her time all the way to date, women’s stories in the West have been increasingly considered valid testimonies, along with accoun ts by people of color and those outside the highest strata of socio-political influence. Therefore, although it is impossible to view history from a wholly objective position, it is still helpful to be aware of such biases.In conclusion, I believe that what Shostak should have done was to strive to consider other sources that could offer insight about the !Kung people, such as official documents (marriage, divorce, and birth records, public notices), archived newspapers (human interest stories, political coverage), and glossy magazines (regional and national views reflecting social trends of the time, setting a context). Although her learning of the language is a great achievement enabling her to establish effective communication with the subject, it serves to tell us only a fragment of the whole picture.This fact takes on a deeper gravity when we consider that the question of truth may have many answers. Nisa’s portrayal of her life is indeed accurate in her own mind. Yet we know that, after all, memory is selective: people’s responses to experiences vary and people’s memories of experiences change with time and influence. Events that happen in a person’s life between lived experiences and recording those events can shape their telling, which only confirms that truth may have many answers.Reference:THE PROBLEM OF ETHNOGRAPHIC REPRESENTATION http://home.pacbell.net/nicnic/ethnographic.html#14Shostak, Marjorie, Nisa: The Life and Words of a!Kung Woman.

Custom Relationship Between Business and Society Essay

The world today believes in change and liberation due to beliefs and values of every society, the quality of living based on individual decisions and moral values are critical in building and of business relationship. It is therefore vital to understand how business and society can be governed and all manner of people and races respected. Every society has taboos and social entities that control its environment; however business and society is based on values that can be created by others though scientific research. According to Weber, The Protestant Ethic is a starting point towards understanding the multiple dimensions of social change. The relationship between business and ethics is interlocked in the sense that a successful company is one which can effectively maintain the relationship which exists between them and the other parties. For effective corporate management, organization varies due to policies and systems of operation in service deliver, most professionals governed by professional code of ethics invent individual personality. Religious beliefs critically affect each individual spiritual being. Today businesses that have strong corporate codes of ethics are performing well in the long-term. Government policies and competition is vital for survival in every business entity, customer expectations and organization relationships to society are critical in branding and corporate image which differentiates company’s offering from those of competitors. To manage it demand for in the long run demands commitment and sound moral behavior. This demonstrates dedication to all stakeholders, ethics enhance how a company operates and also enhances a company’s reputation and this brings more profits to the organizations. MAX WEBER PROTESTANT ETHICS Max Weber a German sociologist and political economist (1864 – 1920) aim at understanding the revolution power based of political stability and control of capitalism. With his social and religious beliefs, he investigated to known why the most economically developed districts were the most favorable to a revolution. In his findings, Weber concluded that higher skilled laborers and personnel were overwhelmingly Protestant. He aimed at bring change and revolution. The argument was based on development and education by the Catholics which he believes lead was a cause to nationality imbalance. Resources were unfairly distributed thus the districts ended up converting protestant, it plumbs the deep cultural forces that affect contemporary work life and the workplace in the capitalist communities, and it plumbs the deep religion forces that affect contemporary work life and the workplace. He professed religion balance between the Catholic and Protestant parents who usually give their children different kinds of education, in which his believe was that education is an equal asset to both the Catholics and protestants’, however he was not font that Catholics have more of a tendency in education while protestants stay in handicrafts and sectors rather than to go into industry. It suggests that their environment has determined the choice peoples occupations seem more likely since for example you would normally expect Catholics to get involved in economic activity. His argument was based on political power and influence and his believe that Protestants had stronger tendencies and capabilities to develop the economy rationalism. To him this was not a philosophy of mere greed but a statement laden with moral language. Creating modern capitalism that affects contemporary life and work place ethically. Lacks of ethics contribute to a state where the corporate bottom lines make profits through immoral acts. This relents to damaged image and leads to corrupt dealings and poor ethical practices. Managers who promote an atmosphere with high ethical standards create a competitive concept that positions a company above rivals. This will impact help increase revenues for the benefit of all stakeholders. SPIRIT OF CAPITALISM Capitalism is an economic system whereby the means of production are privately owned and operated for making profits. The decisions regarding supply, demand, price, distribution, and investment are made within a free market. Profit is sent to owners who invest in businesses, and wages are paid to workers. The world of business is where religion demands high moral and values; Weber’s idea of modern capitalism as growing out of the religious pursuit of wealth meant a change to how wealth existed. Looking at this argument the world today has changed due to advancement of human knowledge and technological advances, religion affects business depending on relationship created among business partners, however religion is an obligation to look at, basically the impact can be based on critical values of entrepreneurs or markets targeted. Every organization is critically evaluated through its promise and purposes to deliver its products and services. The compliment can be on ability to abide by the vision and mission statement. Weber’s argues that the first and probably most vital feature of the spirit of capitalism was that it invested on economizing with high moral significance. Today communication among business entities has created a link to doing business better, the advancement of technology e.g. the use of electronic mode of payment has brought about cross boundary relationships which can easily be manage and monitored. Weber aims of scrutinizing individual strength and builds trust which is critical to business operations. This is to provide opportunities for resistance in the organizational structures with emancipation alongside those for repression and subordination. In most economies equal business opportunities are applied to allow free movement of labour and interest payment are legitimate returns on capital which provides legal mechanism for state in mobilization of funds and partnerships and create a modern state. The challenges in the society today are; highly competitive environments, global warming, inflation, which puts pressure on company’s leaders to create profitable relationships remain competent to create channels which circumvent to stakeholders returns on investment. The pressure of delivering positive results can lead to unethical decisions by individuals. However Governing legal frameworks therefore become critical as a key competency for quality productivity. Every organization has to avoid unethical environment because if it occurs it usually gets passed down through the organization ruining its reputation. In the world today China and India are believed to be â€Å"federal capitalist who excises economical power, capitalism ultimately enforce market regulation. The pricing mechanism coordinates supply and demand within a given market framework, while the visible hand of government enforces the framework and keeps it up to date†. (Bruzz Scott: the root of modern capitalism journal 11 June 2008) LUTHER CONCEPTION CALLING According to Weber his conception calling was on realization that people have got duty to fulfill and obligations imposed on them which must be attain, this believe adds value to letting each individual practice his capabilities and beliefs for betterment of living. He argues that each person has got a legitimate calling or purpose by his God; however the society is a mix of races as others rarely believe in God. He came to believe in absolute obedience to God’s will, and acceptance of the way things were. According to Weber he was trying to understand how certain characteristics of modern culture can be traced to the reformation. Scientifically most of Weber’s unforeseen beliefs are today engulfing physically through research challenging this believes. Today the society demands quality products and services with gratification of immediate results, perhaps a reason some companies practice corporate values to deliver results based of professionalism and not mere religion hindrances. Due to bureaucratic leaderships it is obvious that one’s individual moral capabilities impacts decisions and choices made in a business and in the process of it the immoral acts will decline. This in today business relationship is based on training and staff motivation. The staff morale is critical; at such a case Weber’s religion plays a role as most organization start a day with a word of prayer as a way of building courage and etiquette among employees. Weber’s moral values were that his study will contribute to the understanding of how some ideas become history’s most effective forces. He in his calling was to civilize other believers and create a more ethical responsible society with a better lifestyle. In the modern society Weber also notes that societies having more Protestants have the most developed capitalist economies. Weber’s transformation approach was not personal for monetary gain but based on passion for his Lutheran faith. It is in the best interest of a company to promote universal ethically good behavior in the workplace. This can be through Consumer trust and confidence in a business. This ultimately enhances economical benefits to a company and its network will grow. Thus, Weber concludes that the simple idea of the calling in Lutheranism is at best of limited importance to his study. Modern capitalism is about blended revolution aimed to create systems across boundaries; technology is factor that has influenced positively capitalism development on perspective of social systems, most government political challenges also affects the relationships by compromising relationships management across boundaries. However, this can be done through international marketing e.g. development abroad, franchising licensing and many others or through outsourcing services. Trade is increasingly global in scope today. Technological has improved transportation and communication opportunities and trade is now more practical. Thus, consumers and businesses now have access to the very best products from many different countries. â€Å"Increasingly rapid technology lifecycles also increases the competition among countries as to who can produce the newest in technology. In part to accommodate these realities, countries in the last several decades have taken increasing steps to promote global trade through agreements such as the General Treaty on Trade and Tariffs†. (Lars Perner, Ph.D) At glace ethical organizations create a stable organization culture and affects the level of decision making, the relationship between business and the society is vital, thus ethics is a component of doing good business. It would be a better world if the alternatives to source professionals could be utilized. However a population of unskilled workers is high and various governments’ rules of socials and dictatorship style of management insulates countries with anti market policies creating a non conducive environment for investments. However adapting ethical social governance can change for well created government for capitalism has got to start somewhere due to poor leadership opponents of globalization worry that many of the economic opportunities afforded the world while in many developing countries. CONCLUSION As the world advance and relationships are made, it is vital to understand the impact that matters to our daily life’s devotions. All aspect and merits of life are contacted by beliefs and creation of one’s faith.

Implication Isothermal Amplification Based Methods Detection Infectious Diseases Biology Essay Example

Implication Isothermal Amplification Based Methods Detection Infectious Diseases Biology Essay Example Implication Isothermal Amplification Based Methods Detection Infectious Diseases Biology Essay Implication Isothermal Amplification Based Methods Detection Infectious Diseases Biology Essay Methods for the diagnosing of infective diseases have crawled in the last 2-3 decennaries. Many trials that form the anchor of the modern microbiology research lab are based on really old and labor-intensive engineerings such as microscopy. Invention and execution of PCR had lead to major progresss in country of research and nosologies. However, it requires a thermocycler and longer clip to divide two DNA strands and magnify the needed fragment. Burning demand of the hr include more rapid trials without giving sensitiveness, value-added trials, and point-of-care trials for both high- and low-resource scenes. Over the period of last few old ages, research has been focused on alternate methods to better the diagnosing of infective diseases. These include assorted isothermal amplification-based molecular attacks. In this article, we review these isothermal nucleic acerb elaboration engineerings and their applications along with some of the virtues and demerits of these trials. Keywords: PCR, TMA, NASBA, SDA, LAMP, HAD, cHDA, RCA, SPIA, IMDA, SMART Introduction In vitro Nucleic Acid elaboration was for the first clip described in 1971 ( Kleppe ) . Followed by synthesis of tRNA cistron by primer-directed DNA fix and this was non exponential elaboration. In 1983, Kary Mullis postulated the construct of the polymerase concatenation reaction ( PCR ) but remained theoretical until 1985 when Saiki published the first application of PCR on beta-Globin. Thereafter, polymerase concatenation reaction became anchor of bing research and diagnostic universe. Inventions in biotechnology that combine molecular biological science, microfabrication and bioinformatics are traveling nucleic acerb engineerings from futuristic possibilities to common research lab techniques and manners for disease diagnosings. In this manner, elaboration of nucleic acids is widely used in research, forensics, medical specialty, and agribusiness [ 1 ] . One of the most widely used elaboration methods is the polymerase concatenation reaction ( PCR ) , which is a mark elaboration method [ 2 ] . A PCR reaction typically utilizes two oligonucleotide primers, which are hybridized to the 5and 3ends of the mark sequence, and a Deoxyribonucleic acid polymerase, which can widen the annealed primers by adding on deoxyribonucleoside-triphosphates ( dNTPs ) to bring forth double-stranded merchandises.By raising and take downing the temperature of the reaction mixture, the two strands of the DNA merchandise are separated and can function as templets for the following unit of ammunition of tempering and extension, and the procedure is repeated [ 3 ] . Although PCR has been widely used by research workers, but it is labour intensive, requires expensive thermocycling machine and expertness. Several isothermal elaboration techniques have been developed in the last two decennaries without utilizing thermocycler machine. These non-PCR based methods have exploited the high fidelity polymerase of phages and some accessary proteins for in vitro nucleic acid elaboration. All these methods do non necessitate temperature cycling, operate at a changeless temperature, and offer possible advantages including cost, velocity, portability and decreased sensitiveness to inhibitors over PCR. We here describe the best known isothermal elaboration methods ( such as written text mediated elaboration ( TMA ) or self-sustained sequence reproduction ( 3SR ) , nucleic acid sequence-based elaboration ( NASBA ) , strand displacement elaboration ( SDA ) , loop-mediated isothermal elaboration of DNA ( LAMP ) , helicase-dependent elaboration ( HDA ) , round helicasedependent elaboration ( cHDA ) ) , turn overing circle elaboration ( RCA ) , individual primer isothermal elaboration ( SPIA ) , signal mediated elaboration of RNA engineering ( SMART ) and isothermal multiple supplanting elaboration ( IMDA ) and their applications in molecular diagnosing. 1. TRANSCRIPTION MEDIATED AMPLIFICATION ( TMA ) Transcription mediated elaboration ( TMA ) is RNA written text elaboration system which uses RNA polymerase ( T7 RNA polymerase ) to do RNA from a RNA booster sequences engineered in the primer part, a contrary RNA polymerase ( M-MuLV ) to bring forth complementary Deoxyribonucleic acid from the RNA templets ( Guatelli et al, 1990 ) . This RNA elaboration engineering has been farther improved by presenting a 3rd enzymatic activity, Rnase H, to take the RNA from complementary DNA without the heat-denatured measure ( Fig No.2 ) . Therefore, the thermocycling measure has been eliminated, bring forthing an isothermal elaboration method named self-sustained sequence reproduction ( 3SR ) [ 5 ] . It is single-tube reaction, amplifies either DNA or RNA, and produces RNA amplicons, in contrast to most other nucleic acerb elaboration methods that merely bring forth DNA. It has really rapid dynamicss ensuing in a billion fold elaboration within 15-30 proceedingss. The terminal merchandises of TMA can be detected utilizing gel cataphoresis, fluorescence investigations and colorimetric check. TMA has been used for sensing of N.gonorrhoeae and C. trachomatis ( Hobbs et.al.2008 ) HCV Ferraro et Al. 2008, Gelderblom et al.2007, West Neil febrility ( Ziermann et.al. 2008 ) . 2. NUCLEIC ACID SEQUENCE BASED AMPLIFICATION ( NASBA ) NASBA was developed by J. Compton in 1991who defined it as a primer-dependent engineering that can be used for the uninterrupted elaboration of nucleic acids in a individual mixture at one temperature. NASBA is peculiarly suited to sensing of genomic, ribosomal or messenger RNA. The merchandise of NASBA is ss RNA of the original mark. 108 fold elaboration of the mark may be obtained in 30 min. It utilises activity of 3 enzymes RNA polymerase ( T7 RNA polymerase ) ( RNA dependant RNA Polymerase activity ) to do RNA from a RNA booster sequences engineered in the primer part, a contrary RNA polymerase ( AMV ) to bring forth complementary Deoxyribonucleic acid from the RNA templets and RNAse H to degrade RNA from DNA-RNA loanblend followed by formation of complementary DNA by rearward RNA polymerase enzyme. Again RNA polymerase ( DNA dependant RNA polymerase activity ) to do RNA transcripts from double stranded hence functional T7 RNA booster sequences ( Fig No. 3 ) . The terminal merchandises of NASBA can be detected utilizing gel cataphoresis, fluorescence investigations ( NASBA existent clip ) and colorimetric check ( NASBAELISA ) [ 6-8 ] . Food and Drug Administration office of United States of America ( FDA ) has approved the technique in NucliSence preparation ( NASBAECL ) for molecular sensing of some micro-organisms such as HCV and HIV-1 [ 9, 10 ] . Around 500 articles for designation and sensing of micro-organism using NASBA have been reported. 3. STRAND DISPLACEMENT AMPLIFICATION ( SDA ) Strand-displacement elaboration ( SDA ) is an isothermal technique foremost introduced by Walker et Al. 1992. It combines the ability of a limitation endonuclease to nick the unmodified strand of its mark Deoxyribonucleic acid and the action of an exonuclease-deficient Deoxyribonucleic acid polymerase to widen the 3 terminal at the dent and displace the downstream DNA strand. The displaced strand serves as a templet for an antisense reaction and frailty versa, ensuing in exponential elaboration of the mark DNA ( Figure 5 ) . In the originally designed SDA, a mark DNA sample is heat denatured. Four primers ( B1, B2, S1, and S2 ) , present in surplus, and bind the mark strands at places flanking the sequence to be amplified. Primers S1 and S2 have HincII acknowledgment sequences ( 5 GTTGAC 3 ) located 5 to the mark complementary sequences. The four primers are at the same time extended by exo- klenow utilizing dGTP, dCTP, TTP, and dATP ( I ±S ) . Extension of B1 displaces the S1 primer extension merchandise, S1-ext. Likewise, extension of B2 displaces S2-ext. B2 and S2 bind to displaced S1-ext. B, and S1 bind to displaced S2-ext. Extension and displacement reactions on templets S1-ext and S2-ext green goods two fragments with a hemiphosphorothioate HincII at each terminal and two longer fragments with a hemiphosphorothioate HincII site at merely one terminal. HincII nicking and exo-kle now extension/displacement reactions initiate at these four fragments, automatically come ining the SDA reaction rhythm. These reaction stairss continuously rhythm during the class of elaboration. Present in surplus are two SDA primers ( S1 and S2 ) . The 3end of S1 binds to the 3end of the displaced mark strand T1, organizing a semidetached house with 5overhangs. Likewise, S2 binds T2. The 5overhangs of S1 and S2 contain the HincII acknowledgment sequence ( 5- GTTGAC -3 . Exo- klenow extends the 3ends of the semidetached houses utilizing dGTP, dCTP, TTP, and dATP ( I ±S ) , which produces hemiphosphorothioate acknowledgment sites on S1: T1 and S2: T2. HincII nicks the unmodified primer strands of the hemiphosphorothioate acknowledgment sites, go forthing integral the modified complementary strands. Exo- klenow extends the 3end at the dent on S1: T1 and displaces the downstream strand that is tantamount to T2. Likewise, extension at the dent on S2: T2 consequences in supplanting of T1. Nicking and polymerization/displacement stairss rhythm continuously on S1: T1 and S2: T2 because extension at a nick regenerates a nickable HincII acknowledgment site. Target elaboration is exponential because strands displaced from S1: T1 serve as mark for S2 while strands displaced from S2: T2 serve as mark for S1 [ 16 ] . SDA engineering has been used chiefly for clinical diagnosing of infective diseases such as chlamydia and gonorrhoea [ 17-20 ] . This technique can be used for isothermal elaboration of RNA templets in RT-SDA format by adding rearward RNA polymerase to the original procedure [ 21, 22 ] . SDA has been performed on C. trachomatis Verteramo et. Al. 2009, N. gonorrhoeae and C.trachomatis Van et Al. 2001 Cosentino, et Al. 1999, M. TB Hellyer, et Al. 1999. 4. LOOP-MEDIATED ISOTHERMAL AMPLIFICATION ( LAMP ) LOOP-MEDIATED ISOTHERMAL AMPLIFICATION ( LAMP ) is a fresh method that amplify DNA with high specificity, efficiency, celerity at isothermal conditions and relies on car cycling strand supplanting DNA synthesis by Bst DNA polymerase foremost develop by, Notomi, T. et Al. in 2000. It can straight be performed on clinical samples ( DNA Isolation is optional ) . Bst polymerase is thermostable DNA polymerase fromA Bacillus stearothermophilusA ( N3468 ) and contains the 5A? a† Ã¢â‚¬â„¢ 3A? polymerase activity, strand displacement activity but lacks 5A? a† Ã¢â‚¬â„¢3A? exonuclease activity, 3 a† Ã¢â‚¬â„¢5proof reading activity. It uses 4 primers.Two inner primers ( FIP and BIP ) and two outer primers ( F3 and B3 ) [ 29 ] . The elaboration merchandises are stem-loop DNA structures with several upside-down repetitions of the mark and cauliflower-like constructions with multiple cringles ( Figure 7 ) . The LAMP method is besides a extremely efficient elaboration method that allows the synthesis of big sums of Deoxyribonucleic acid in a short clip. As a consequence, pyrophosphate ions are produced in big sums and signifier white precipitates of Mg pyrophosphate. Judging the presence or absence of this white precipitate allows easy differentiation of whether nucleic acid was amplified by the LAMP method [ 30 ] . However the other formats such as gel cataphoresis, real-time turbidimetry, and fluorescence investigations have been used for sensing of LAMP merchandises [ 31, 32 ] . This engineering has widely been used for molecular sensing of several micro-organisms by research workers and it can be a suited pick for design and development of rapid molecular trials in the field [ 33, 34 ] . There has been successful study of 10493 articles for sensing and designation of bacteriums, parasites, viruses and Fungis by LAMP. 5. Rolled CIRCLE AMPLIFICATION ( RCA ) Rolling circle elaboration ( RCA ) generates multiple transcripts of a sequence for the usage in vitro DNA elaboration adapted from in vivo turn overing circle DNA reproduction [ 23, 24 ] . In its original preparation, the RCA reaction involves legion unit of ammunitions of isothermal enzymatic synthesis in which phi 29 DNA polymerase extends a circle-hybridized primer by continuously come oning around the round DNA investigation of several twelve bases to retroflex its sequence over and over once more ( Figure 6 ) [ 25, 26 ] . The individual isolated nature of amplicons in instance of additive RCA may be good for subsequent uses with these DNAs towards their sensing [ 24 ] . This reaction is widely used for diagnostic intents in direct or indirect sensing of different DNA/RNA, protein, and other biomarkers via a set of assorted bimolecular acknowledgment events. A similar reaction was described for RNA polymerases every bit good, but the RNA-generated procedure does non necessitate any hybridization-dependent priming [ 27 ] . Therefore, the latter is merely used to bring forth functional RNA sequences, such as RNA ladders and self-processing ribozymes. Recently, RCA has been farther developed in a technique, named multiply-primed turn overing circle elaboration ( multiply-primed RCA ) that uses the alone belongingss of phi29 DNA polymerase and random primers to accomplish a 10,000-fold elaboration ( Figure 6 ) . The procedure allows elaboration of round DNA straight from cells or plaques, bring forthing, or cloning [ 28 ] . RCA-based attacks have late been pulling attending of diagnostics-oriented biotech companies and research centres for cistron trials and immunochemical assaies, SNP marking and sequencing template readying, single-cell analysis systems, and cistron look surveies [ 26 ] . Johne et Al. 2009 and Rector et al.2004 optimized RCA for Begomovirus and type 16 Human villoma virus severally. 6. HELICASE-DEPENDENT AMPLIFICATION ( HDA ) Helicase-dependent elaboration ( HDA ) is based on the unwinding activity of a DNA helicase [ 41 ] . This procedure uses a helicase, instead than heat, to divide the two strands of a Deoxyribonucleic acid duplex bring forthing single-stranded templets for the intent of in vitro elaboration of a mark nucleic acerb [ 42 ] . Sequence-specific primers hybridize to the templets and are so extended by Deoxyribonucleic acid polymerases to magnify the mark sequence. This procedure repeats itself so that exponential elaboration can be achieved at a individual temperature ( Figure 9 ) . This procedure allows multiple rhythms of reproduction to be performed at a individual incubation temperature, wholly extinguishing the demand for thermo cycling equipment [ 3 ] . The HDA amplicons can be detected utilizing gel cataphoresis, real-time format, and enzyme-linked immunosorbent check ( ELISA ) . [ 41-45 ] HDA has been used for designation of S. aureus, MRSA, Goldmever et al 2008, M. TB Gill, et Al. 2007, H. pylori Gill, et Al. 2007. 7. CIRCULAR HELICASE-DEPENDENT AMPLIFICATION ( cHDA ) round Helicase-dependent elaboration ( cHDA ) is used for magnifying nucleic acids from a round Deoxyribonucleic acid templet. This system combines a Deoxyribonucleic acid polymerase and a helicase readying to magnify a mark sequence every bit good as the full round Deoxyribonucleic acid templet incorporating the mark sequence [ 50 ] . The technique is based on the T7 reproduction machinery, which includes the processive T7 helicase, an exonuclease-deficient T7 DNA polymerase ( T7 sequenase ) and the T7 Gp2.5 single-stranded DNA binding ( SSB ) protein. After the duplex DNA templet is unwound by T7 helicase, specific primers anneal to the separated DNA strands and T7 sequenase extends the 3end of each primer by a rolled circle mechanism to magnify non merely a part defined by the primers but besides uninterrupted concatemers of the templet ( Figure 11 ) . The procedure can be carried out at one temperature ( 25a- ¦C ) for the full procedure. Amplification can be performed utilizing purified plasmid Deoxyribonucleic acid or petroleum cell lysate can magnify inserts every bit big as 10 kilo base braces [ 50 ] . Xu, et al. 2006 performed cHDA on E. coli. 8. SIGNAL MEDIATED AMPLIFICATION OF RNA TECHNOLOGY ( SMART ) SMART is based on the formation of a tripartite junction ( 3WJ ) construction. The method relies on signal elaboration and does non necessitate thermic cycling or affect the copying of mark sequences. The check generates a signal that is extremely target dependant and is appropriate for the sensing of DNA or RNA marks [ 11 ] . It consists of two single-stranded oligonucleotide probes extension investigation and templet investigation, each investigation includes one part that can crossbreed to the mark at next places and another, much shorter, part that hybridizes to the other investigation. The two investigations are annealed to each other in the presence of the specific mark, so organizing a 3WJ ( Figure 4A ) . After 3WJ formation, Bst DNA polymerase extends the short ( extension ) investigation by copying the opposing templet investigation to bring forth a two-base hit stranded T7 RNA polymerase booster sequence ( Figure 4B ) . This dual stranded hence functional booster sequences allows T7 RNA polymerase to adhere and bring forth multiple transcripts of an RNA amplicons and hence being produced merely when a specific mark is present to let 3WJ formation. Each RNA amplicons may itself be amplified by adhering to a 2nd templet oligonucleotide ( investigation for elaboration ) and is extended by DNA polymerase to bring forth a double-stranded booster, taking to written text which increases the RNA amplicons can be detected by an enzyme linked oligosorbent check ( ELOSA ) or in existent clip format [ 12,13 ] . This procedure is in fact a signal elaboration method that the mark sequence is non itself amplified [ 14 ] . SMART has been used for sensing of cyanophages ( Hall, et Al. 2002 ) and E. coli ( Wharam, et Al. 2001 ) . 9. ISOTHERMAL MULTIPLE DISPLACEMENT AMPLIFICATION ( IMDA ) Isothermal Multiple Displacement Amplification ( IMDA ) is based on strand supplanting reproduction of the nucleic acid sequences by multiple primers [ 35 ] . Two sets of primers are used, a right set and a left set ( Figure 8 ) . The primers in the right set are complementary to one strand of the nucleic acid molecule to be amplified and the primers in the left set are complementary to the opposite strand. The 5ends of primers in both sets are distal to the nucleic acerb sequence of involvement where the primers have hybridized to the nucleic acid sequence molecule to be amplified. Amplification is done with the aid of phi29 DNA polymerase is a extremely processive enzyme that incorporates at least 70,000 bases in one binding event entirely with 3-5proof reading and maroon supplanting activity returns by reproduction initiated at each primer and go oning through the nucleic acerb sequence of involvement. A cardinal characteristic of this method is the supplanting of step ining prime rs during reproduction by the polymerase. In another preferable signifier of the method, referred to as whole genome strand supplanting elaboration, a random set of primers is used to randomly prime a sample of genomic nucleic acid [ 36, 37 ] . Amplification returns by reproduction with a extremely processive polymerase initiated at each primer and go oning until self-generated expiration. In this manner, multiple overlapping transcripts of the full genome to be synthesized in a short clip [ 38-40 ] . IMDA has been successfully used for whole genome elaboration from Plasma Lu, et Al. 2005, Blood, bone marrow aspirates, tissue biopsy Luthra, et Al. 2004, Blood Hosono, et Al. 2003. 10. SINGLE PRIMER ISOTHERMAL AMPLIFICATION ( SPIA ) This elaboration engineering uses a individual chimeric primer for elaboration of DNA ( SPIA ) and RNA ( Ribo-SPIA ) [ 46 ] . SPIA employs a individual, target-specific chimeral primer composed of deoxyribonucleotides at the 3- terminal and ribonucleotides at its 5- terminal, RNase H, and a Deoxyribonucleic acid polymerase with a strong strand supplanting activity. Amplification is initiated by crossbreeding the chimeral primer to a complementary sequence in the mark DNA molecule. DNA polymerase initiates primer extension of the hybridized primer and extends along the mark DNA strand. Following induction of the primer extension measure, the 5 RNA part of the drawn-out primer ( RNA-DNA loanblend ) is cleaved by RNase H, therefore liberating portion of the primer-binding site on the mark DNA strand signifier binding of a new chimeral primer. The freshly bound primer competes with the old primer extension merchandise for adhering to the complementary DNA mark sequence and is stabilized by adhering of DNA polymerase and displaces the 5 terminal of the old extension merchandise. As reproduction is once more initiated by primer extension, RNase H cleavage of the 5 RNA part of the freshly extended primer once more frees portion of the primer binding site for subsequent primer binding and reproduction rhythm is repeated. SPIA elaboration can be used for planetary genomic DNA elaboration and for the elaboration of specific genomic sequences and man-made oligonucleotide DNA marks. Ribo-SPIA is likewise suited for planetary and target-specific RNA elaboration ( Figure 10 ) [ 47-49 ] . Ribo-SPIA engineering provides an elegant method for additive, isothermal elaboration of the messenger RNA species in a entire RNA population. Replication is initiated and repeated up to 10,000 times off of each original transcript. Therefore, this procedure can be used for elaboration of big populations of nucleic acid species, which are limited in biological samples, as are normally enc ountered in clinical researches [ 46 ] . Decision In this survey, we described the well studied isothermal engineerings for nucleic acerb elaboration that offer several advantages over PCR in that they eliminate the demand for an expensive and cost-intensive thermocycler. However, these isothermal elaboration engineerings have some limitations that confine their employment in some facets of molecular biological science. For illustration, TMAs requirement is three different enzymatic stairss ( transcription/cDNA synthesis/RNA debasement ) to carry through an isothermal RNA elaboration, [ 4 ] and its get downing stuff is limited to individual stranded nucleic acid/RNA. SDA needs four primers to bring forth initial amplicons and modified deoxynucleotides to supply strand-specific nicking [ 15, 16 ] and it is inefficient at magnifying long mark sequences. LAMP insists upon four to six specific primers that their designs are complicated for new user [ 51 ] . Besides, its concluding merchandise is a complex mixture of stem-loop cauliflower-like DNA constructions of assorted sizes. Nagamine et Al. have devised excess stairss to obtain unvarying single-stranded Deoxyribonucleic acid from LAMP merchandises. This is preferred for assorted hybridisation techniques. The advanced method uses the thermo stable TspRI limitation enzyme to digest elaboration merchandise, [ 52 ] and an extra primer hybridized to the 9-nt 3overhang at the TspRI cleavage site to displace single-stranded Deoxyribonucleic acid by primer extension [ 53 ] . Recently, Kaneko et Al. evaluated the tolerance of LAMP to a civilization medium and some biological substances [ 55 ] . Harmonizing to their survey, the sensitiveness of LAMP was less affected by the assorted constituents of the clinical samples than was PCR ; hence, DNA purification can be omitted. On the other manus, some of these methods such as HDA have a simple reaction strategy, in which a mark sequence can be amplified by two flanking primers, similar to PCR [ 41, 42 ] . One of the most of import advantages of the isothermal elaboration techniques is related to their tolerances to some repressive stuffs that affect the PCR efficiency. Another illustration is about HDA ; a pathogen genomic Deoxyribonucleic acid can even be detected in a human blood sample [ 41 ] . This demonstrates that HDA can be performed on petroleum samples and has the possible to be used as a diagnostic tool. RCA holds a expressed place in DNA nosologies among other isothermal elaboration techniques due to its hardiness and simpleness. As compared with RCA, all other isothermal methods of signal, investigation, or aim DNA elaboration, such as transcription-based system, maroon displacement attack or loop-mediated techniques are instead complicated and in most instances they require anterior assay optimisation [ 26, 54 ] . Although, SDA and RCA are described as isothermal elaboration systems, both methods require an initial heat denaturation measure. Another of import advantage for the isothermal elaboration techniques is no demand to initial heat denaturation at a high temperature followed by elaboration at a lower temperature. This belongings has been reported about some isothermal elaboration methods. For illustration, because there is no necessity for heat denaturation of the templet DNAs, LAMP can be used more easy and quickly in molecular medical specialty [ 56 ] . As DNA helicase can wind off double-stranded mark Deoxyribonucleic acid at the beginning of the reaction, the full HDA reaction can be performed at one temperature [ 41 ] . Beyond the shadow of uncertainty, these isothermal elaboration based engineerings be at discrepancy with their nature and volume of sample required, processing of specimen, and methods of elaboration and sensing. In spite, of these many restrictions isothermal elaborations based techniques would successfully vie with its widely employed thermic cycler based predecessor ( PCR ) for the figure of diagnostic applications. On the whole, simpleness and isothermal nature of these methods offer great potencies for the development of handheld DNA diagnostic devices that could be used to observe pathogens at point-of-care or in the field.

Eunotosaurus - Facts and Figures

Eunotosaurus - Facts and Figures Name: Eunotosaurus (Greek for original noded lizard); pronounced you-NO-toe-SORE-us Habitat: Swamps of southern Africa Historical Period: Late Permian (260-255 million years ago) Size and Weight: About one foot long and a few pounds Diet: Unknown; possibly omnivorous Distinguishing Characteristics: Small size; wide, shell-like ribs About Eunotosaurus The ultimate origin of turtles and tortoises is still shrouded in mystery, but many paleontologists believe that these shelled reptiles can trace their ancestry all the way back to the late Permian Eunotosaurus. The striking thing about this prehistoric reptile is that it possessed wide, elongated ribs that curved around its back, a kind of proto-shell that one can easily imagine evolving (over the course of tens of millions of years) into the giant carapaces of Protostega and Meiolania. As to what kind of animal Eunotosaurus itself was, thats a matter of debate; some experts think it was a pareiasaur, a family of ancient reptiles best represented by Scutosaurus. Recently, researchers at Yale University made a major discovery that cements Eunotosaurus at the root of the testudine family tree. Technically, modern turtles and tortoises are anapsid reptiles, meaning they lack characteristic structural holes on the sides of their skulls. Investigating the fossilized skull of a juvenile Eunotosaurus, the Yale scientists identified small openings characteristic of diapsid reptiles (the vast family that includes crocodiles, dinosaurs and modern birds) that closed up later in life. What this means is that anapsid testudines almost certainly evolved from diapsid reptiles some time during the Permian period, which would rule out the proposed pareiasaur origin mentioned above. Given the hypothesis that Eunotosaurus was ancestral to modern turtles, what was the reason for this reptiles elongated ribs? The most likely explanation is that its slightly rounded and expanded ribcage would have made Eunotosaurus harder to bite through and swallow; otherwise, this foot-long reptile would have been easy pickings for the large, predatory therapsids of ifs southern African ecosystem. If this anatomical bulge gave Eunotosaurus even a slight edge in survival, it makes sense that future turtles and tortoises would improve on this body planto the extent that the giant turtles of the later Mesozoic Era were virtually immune to predation as adults (though hatchlings, of course, could easily be gobbled up as they emerged from their eggs).
