Poetry Explication Essay Example for Free

Poetry Explication Essay Wordsworth is one among the best five poets in English. He wrote many poems and most of them are best known for its treatment of love for nature. â€Å"The Daffodils†, â€Å"Lines Written in Early Spring†, â€Å"To the Cuckoo†, and â€Å"My Heart Leaps Up† are very few of his poems in which the role of nature is predominant. By the close reading of the poems it is obvious that he is an ardent lover of nature. And he has the quality to heal all his deep sufferings by enjoying nature. And he insists his readers that to live in touch with nature and it will cure all their problems. Through his poems he gave such a healing power to nature. In most of his poems he considered nature as a living personality. He is a very sensitive to all changes occurred in nature. I WANTERED LONELY AS A CLOUD (THE DAFFODILS) His poem â€Å"I Wandered Lonely as a Cloud† is one of the most celebrated poem. In which the poet describes about a time when he wandered like a cloud through vales and hills. From the first line of this poem it is clear that the poet feels lonely at the time of writing this poem. Finally he saw a group of daffodils which are â€Å"fluttering and dancing in the breeze†. This is all about the first stanza of this poem. In its second stanza he started describe about the daffodils. The flowers seemed never ending so he compares it with shining stars in the Milky Way. He assumes that he might see ten thousand daffodils at a glance. This shows that the flowers are countless or large in number. And they are â€Å"tossing their heads and sprightly dance†. Here the poet is depressed internally but he tries to find happiness from his surrounding nature. In third stanza he compares the waves of the lake and daffodils. But he says that daffodils have more â€Å"glee† than the â€Å"sparking† lake. And he says that a poet can’t do anything but enjoying it. Even in his loneliness he feels some happiness inside his mind. He says that â€Å"in such a jocunt company† a poet can only enjoy it nothing more than that. He starred at the scene for a long time and he couldn’t understand what he gained by gazing at it. Here he says that nature has a power to attract any man’s attention even if the man is in depressed mood. In its last stanza he describes about what he gained from this experience. He says whenever he feels â€Å"pensive† or â€Å"vacant† this experience fills happiness in the mind of the poet and he started dancing with that flowers. It shows his change of mood after take a look of those flowers. â€Å"They flash upon that inward eye Which is the bliss of solitude; And then my heart with pleasure fills, And dances with the daffodils. † The dancing daffodils have that much influence in the mind of the poet. This experience was capable to heal the inner sufferings of him. From this poem he tries to teach the reader about the importance of man’s connection with nature. Only nature can give utmost pleasure to man than any material possession. MY HEART LEAPS UP (THE RAINBOW) This poem is one of Wordsworth’s widely accepted poems. In which he depicts about his excitements when he saw a rainbow in the sky. This poem is well known because of its simplicity in theme and its treatment of nature. Through this poem he reveals to his readers that how childishly he keeps enjoying nature. He used to see rainbow in the sky from his childhood itself. Now he is a grown up man but still he didn’t lose his spirit towards nature. In short his love for nature is consistent. We can understand it by referring many of his poems. This poem is started with the line â€Å"My heart leaps up when I behold A rainbow in the sky:† From the first line itself he started describing his cheerful experience when he saw a rainbow in the sky. According to him there is no age bound in enjoying nature. He used here present, past and future tenses only to denote his spirit of enjoying the nature. â€Å"So was it when my life began; So is it now I am a man; So be it when I shall grow old,† He says that when he was in his childhood the view of rainbow made the same effect which he feels now, in his manhood. And he wishes to continue like this in his future also. In his mind leading a life without keeping any connection with nature is worse than death. He says that in his future days if he is not capable to enjoy it then â€Å"let me die! †. He can’t think a life without nature because it is everything for him. And through these lines he also shows his consistent love towards nature. His love has same spirit throughout his life. And till his end he wishes to live in nature’s lap. Towards the end of this poem he says that â€Å"The child is father of the man;† which gives a paradoxical meaning here. Commonly we know that man is the father of child. But here he was not talking about its direct meaning. He only means that from the childhood begins manhood. Here the word â€Å"father† means one from whom something begins. The main idea of the poem lies in this line, i.e. , the present is the outcome of past and like this future will be the outcome of present. And in its concluding lines he shows his deep desire to live in connection with nature by enjoying all its varieties. â€Å"And I could wish my days to be Bound each to each by natural piety. † Through these lines he indirectly talks about his immense desire to go back to his childhood. In that age he was very cheerful. Now in his adulthood, because of the bitter experiences of his life, he wishes to attain his childhood once again and he finds that nature is the best mean to achieve it. The themes of â€Å"childhood† and â€Å"nature† are best described through this poem. â€Å"LINES WRITTEN IN EARLY SPRING†: It is a simple, lyric poem. The poet himself said in this poem that he wrote this when he sat under the shade of a group of trees. He was in a relaxing mood at that time and he sat there for a long time by enjoying the music or the sounds from his surroundings. Suddenly the music changes to a melancholy note when he started thinking about humanity. â€Å"In that sweet mood when pleasant thoughts Bring sad thoughts to the mind. † Personally the poet was in a depressed situation at that time. Because of the French Revolution there were problems concerning poverty and society. Moreover he was not take care by his uncle, who was supposed to take care of him since the death of his father, after his graduation. But when he sat under the trees he felt better and slowly it act like a healing balm of his sufferings. But suddenly things have changed. He says that the beautiful sight of nature is a bridge from human soul to god. According to him natural sights are enough to give a perpetual bliss to his mind. â€Å"To her fair works did Nature link The human soul that through me ran;† Through these lines the poet tries to spiritualize nature. He knows that spiritual life is happier than material life. Now his tiresome heart is in search for eternal pleasure. Nature is a perfect creation of god so worshipping it will also give bliss. But the thought of humanity again started disturbing him. And he thinks pathetically about the treatment given to a man by his fellow beings. â€Å"And much it grieved my heart to think What man has made of man. † From these lines he tries to say that all the sufferings of man are only because of the drifting away from nature. According to him nature is the mother of humans. From there only we get complete compensation from all our sufferings. So he indirectly says that men can’t exist without nature. Then he started describing about the flowers in that place. Primrose, periwinkle like flowers are well grown there. After gazing at them he realized that all the flowers are enjoying all their actions even their breathing. From his surroundings he wish acquire some happiness and thus feel an internal bliss. â€Å"The birds around me hopped and played, Their thoughts I cannot measure: But the least motion which they made, It seemed a thrill of pleasure Secondly he started looking at the birds around him. They were â€Å"hopped† and â€Å"played† there. Then he says that he was not able to understand their thoughts but even in their small movements poet could feel â€Å"a thrill of pleasure† in them. Poet’s mind is wounded now. But the pleasant picture of the nature changes his mood and brings happiness slowly. In its fourth stanza he started describing about the trees around him. They were all spreading their leaves to breathe the fresh air. But their also he could see only happiness. He came to a realization that nature itself is blissful. All the creatures which are living in connection with nature are all blessed with peace and happiness. In the final stanza he concludes the poem with an important question that is â€Å"what man has made of man? † He became clear about the fact that drifting away from nature is the cause of all tragedies in human life. This realization ache him very harshly. â€Å"Have I not reason to lament What Man has made of Man? † According to him man himself is only responsible for their sufferings. Throughout the poem the pleasure which he describes is something spiritual or divine and the union of man and nature is also the plan of god. Here it is well expressed the poet’s capacity to spiritualize nature. Thus this poem is all about the relationship between man and nature. â€Å"TO THE CUCKOO†: This poem is one of the best poem in which nature is reflected. Throughout this poem the poet thus the speaker addressing a bird cuckoo. Through this poem the poet welcomes the spring season in the most elegant way. He from his childhood noticed that from the beginning of this season nature seems more beautiful with the â€Å"wandering voice† of the bird cuckoo. And in this poem he indirectly depicting about his belief in supernatural elements and he states that this earth is not only for humans but also for animals, birds, supernatural elements like fairies etc. He starts the poem by calling the bird cuckoo as â€Å"a BLITHE New Comer†. He was attracted by its double fold shouting than anything. The bird is not visible to the poet. So in utter confusion he asks the bird that, â€Å"shall I call thee bird, / Or but a wandering voice? † It also shows his interest to see that bird. In its first stanza he talks about his happiness when he hear the voice of the bird. In his second stanza he describes about when he heard the shouting of the bird cuckoo. When he lied on grass he heard the voice passing through â€Å"hills to hill† but he couldn’t fix the bird and thus the shouting seems to him as a wandering voice. Even he became in confusion that whether the bird is shouting from far away or nearby place. Thus the twofold sound of that bird made him a wanderer. Wordsworth is best known as the poet of eyes and ear. In his third stanza he talks about his pleasure and his experiences after seeing that cuckoo. â€Å"Though babbling only to the Vale, Of Sunshine and of flowers, Thou bringest unto me a tale Of visionary hours. † The valley which was filled with sunshine and flowers seemed more beautiful with the voice of the bird. It gives a feast to his eyes and ears. So it made him to stay there for a long time. It brings happiness to his mind. So whenever he heard its voice his urge to see that bird increases. And in the next stanza he addresses the bird as â€Å"darling of the spring† and he welcomes it to the season. And he says to the bird that the bird is only an invisible thing to him. So he feels that the voice of that bird is something mysteries. Even an unknown sound from nature has profound influence in poet’s mind. That’s why it easily catches the attention of the poet. In its fifth stanza he describes about his childhood. Even in his childhood he wandered a lot to see this bird. He tried to see the bird by following its voice. â€Å"The same whom in my school-boy days I listened to; that Cry Which made me look a thousand ways In bush, and tree, and sky. † He says that even from his boyhood age he was fully attracted by the catching beauty of nature. In his childhood also he used to listen its music but then also he didn’t get a chance to see that bird. The bird stays by hiding itself and through its sweet sound it makes the nature more alive and thus it tries to increase its overall beauty. In his childhood he often searched it â€Å"In bush, tree and sky. † Still he keeps searching it with a hope of success. So these lines also show the theme of hope also. He didn’t tire with his thousands of attempt to see that bird. All his failures made him to search more and more. So by observing nature he got a hope for his future. He believes that one day he will meet the owner of that wandering mysterious voice. In its next two stanzas he depicts about his theme of hope and childhood. Even in his manhood also he is wandering for that bird. He has a spark of hope by the shouting of that bird. He keeps an ardent love towards the bird even if he didn’t see that bird yet. And he says that when he lied on the grass and hear the voice, it made a nostalgic effect  to his mind. He started thinking about his â€Å"golden time†, childhood. From the line, â€Å"And listen, till I do beget That golden time again. † It is obvious that his childhood was full of happiness. That is why he referred it with the word â€Å"golden time†. The music of cuckoo had made this much influence in the mind of the poet. In its final stanza he gives a supernatural power to that bird. He calls it as â€Å"O blessed bird! †. From our childhood itself we heard about the stories of fairies. Fairies are some supernatural elements which help and give happiness to others. So to him the bird cuckoo also like this. It gives intense pleasure to the mind of the people. With its sweet voice it heals the incurable wounds of the mind. In his last stanzas he indirectly depicts about his believe in supernatural elements like fairy. â€Å"O blessed Bird! the earth we pace Again appears to be An unsubstantial, faery place; That is fit home for Thee! † Through this line he says that this world is not only for humans but also for animals and other super natural elements. In his eyes the cuckoo bird is a blessed one because it has the power to heal the inner sorrows of men and it fills eternal bliss in to the mind of the humans. This poem dramatizes the conflict between appearance and reality, particularly as this conflict relates to the central symbol of the poem, the goose fish. The speaker relates the tale of two lovers who encounter a dead fish on the beach after sharing their affection with one another. While looking at the fish, the couple ponders the meaning of this fish. Taken figuratively, the goose fish occupies many roles. As the speaker overlooks the events taking place between two lovers on a beach, he introduces the goose fish as playing the part of an intruder: â€Å"Until they saw†¦ / As though the whole world had found them out, / The goose fish†¦Ã¢â‚¬  (15-17). Shortly after the lovers witness the goose fish, they ponder over what the fish’s big toothy grin â€Å"would express, / So finished a comedian† (30-31). The speaker then expresses the lovers’ thoughts that delegate the fish as an emblem of their passionate love and an optimist of their relationship. Finally, after conveying the numerous roles that the lovers attribute to the fish, the speaker expresses the lovers’ final decision to call the goose fish their patriarch who blesses their union. In reality, the fish can not realistically satisfy these roles because it has died. In this way, the speaker communicates the several roles that the lovers ascribe to the goose fish. However, the poem begins with several oddities that hint to the fact that this poem expresses more than it’s literal words. For example, the poem follows the iambic tetrameter form with each stanza closing in an iambic trimeter line. The form of the poem as well as the speaker’s neutral attitude toward the events that take place create a philosophical and detached tone that suggest that the objects and events within the poem should not be interpreted according to their denotations. Also, the rhetoric of the first line illustrates that the words in that line do not simply describe the beach. The speaker uses long vowel sounds to create the long stretch of beach that the lovers inhabit: â€Å"On the long shore, lit by the moon† (1). The syntax conforms to traditional rules so that the speaker can explicitly narrate the action happening between the two lovers: â€Å"Two lovers suddenly embraced / So that their shadows were as one† (3-4). The lovers share an intimate moment that expresses their love for one another. The vocabulary that the speaker uses such as â€Å"graced,† â€Å"prized,† and â€Å"emparadised† suggests that whenever the couple gets together, they enter their own fantasy dream world that consists of just themselves. In the second stanza, the speaker replaces his long, flowing lines with short, abrupt words to convey the fright that the two lovers experience when an outsider intrudes upon their fantasy world: â€Å"Then, as if shaken by stage-fright / Beneath the hard moon’s bony light,† (10-11). The goose fish, the central symbol of the poem, introduces himself to the pair of lovers. Even though the fish looks deceased, the use of irony that the speaker employs describes the role of the goose fish as an intruder: â€Å"Until they saw, there underfoot, / As though the world had found them out, / The goose fish turning up, though dead, / His hugely grinning head† (15-18). The normal structure of the speaker’s sentence builds up to the suspense of finding out who has trespassed into the lovers’ secret world: â€Å"They stood together on the sand / Embarrassed in each other’s sight / But still conspiring hand in hand,† (12-14). In the third stanza, the speaker describes the importance of the interrupting goose fish on the couple through an iambic trimeter line: â€Å"The only way that could be known / To make a world their own† (26-27). The lovers express astonishment in how a fish has infiltrated their fantasy world. Thus, they try to attribute their own special meaning to the fish to make him a part of their world. The speaker blends the symbols of the moon and the fish to show the merging of the heavenly, or the appearance, with the earthly, or the reality: â€Å"There in the china light he lay, / Most ancient and corrupt and gray† (19-20). As the speaker tells about the fish, he inverts the order of his sentence. The fish’s description follows the introduction of the fish. The speaker reverses his word order to place emphasis on the comparison between the heavenly moon and the earthly goose fish. Descriptive words such as â€Å"fragile† and â€Å"violence† transform the lovers’ dream world into a place of horror because an unwelcome visitor joins them. In the last two stanzas of this poem, the goose fish becomes transformed into three different roles as the lovers attempt to decipher the fish’s true meaning. At first they believe that his â€Å"wide and moony grin† transforms the fish into a comedian (28). The use of the word moony to describe the fish fully joins the symbols of the moon and the fish together. This merge represents the unity of the cosmos and that although the lovers appear to exist only in their own dream world, they still find themselves stuck in reality. The couple quickly determines that the fish does not serve as a symbol of humor, but as an emblem of their love. â€Å"But took it for an emblem of / Their sudden, new and guilty love† (33-34). Through the use of short words, the speaker infuses energy into the lovers’ new interpretation of the goose fish to convey passion and lust behind the lovers’ relationship. Finally, the couple decides to look to the fish as their patriarch and friend. When conveying this final conclusion, the speaker expresses the naivete of the lovers and their desperate attempts to extract blessings from the goose fish. However, the lovers overlook the fact that the fish has died. This use of irony shows how the appearance of the fish symbolizes a personal connection to the lovers while in reality, the dead fish cannot fulfill this role. The visual division of this poem into five stanzas serves to create a play that consists of five acts. The lovers represent the actors of a drama. The fish becomes the unwelcome audience as the lovers share their intimacy with one another. When the lovers realize that something has watched their actions, they shiver with embarrassment, or stage-fright. While pondering over the goose fish, they stand hand in hand as if waiting for the curtain call. The goose fish appears to act as the comedian whose play may end in success or failure of the lovers’ relationship. In this way, the poet reinforces the conflict between the appearance of the numerous roles of the goose fish and the reality that the goose fish no longer lives.

Organizational Change and Theory Paper Essay Organizational Change and Theory Paper Introduction   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The aspect of managing organizational change is very crucial to any given organization. Organizational change is the execution of new technologies and procedures with an aim of realigning the organization to the changing demands of the firm or benefit from on the business opportunities. The purpose of this paper is to analyze how implementation of new technology of computerized charting was effectively managed in the hospital.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Nurses have to deal with the new change of computerized charting though it is hardly a new technology. However, several PC-challenged healthcare experts have taken keen interest to become conversant with this new method to patient information management. Taking interest to increase personal skills and marketability as well as being proactive is likely to influence the nursing career in a positive manner. Recent research findings indicate that more institutions are investing in capturing data by electronic means. The keys to computerized charting in modern market, there are various software vendors and alternatives to choose from. In the office I use epic computer software. The use of electronic means is overwhelming at first, but an individual becomes used to with time. It is much better compared to paper charting (Richards Keogh, 2008).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Many health professionals leaned how to work with epic software in their first day of orientation. There is a lot of improvement since most nurses are able to enter their orders themselves. The epic software will enable all the nurses in the institution to use the system from the basic triage to discharge from inpatient. However, there are some resentment about the system since some nurses find it inefficient claiming that the system crashes down frequently for several hours. Others find it very difficult to use especially to the nurses working on the rapid response departments and it’s a challenge to work on a patients without their medical histories, allergies, procedures and meds. The hospital copes with this problem by having backup system. There are also computer hubs where all nurses can print up their chart, though it is also a sticky situation to be used by the entire hospital (Retrieved from http://www.medscape.com/viewarti cle/810573).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The epic program is very effective when it is working since nurses can enter their progress notes and orders. The other problem that the hospital has to deal with is that there is high probability of nurses clicking the wrong orders. The other problem is that sometimes the system is too slow. The nurses are asked to been with the system and have specific way of entering individual orders for easy identification since one click on the system shows very many orders. However, nurses are given opportunity to access any patient’s order from anywhere at any given time since they can use epic system at the same time (Retrieved from http://allnurses.com/nursing-informatics/epic-computer-program-280071.html).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The hospital’s IT department has provided enough memory and large servers which is a very significant move. This enables the nurses to make their own orders effectively without the system breakdown or becoming too slow. The epic system might be complicated at first since some nurses find it difficult to locate their flow sheets. The nurses who became used to the system are able to program their favorite flow sheets which make it effortless for the nurse to remember to fill them later. The institution has managed this change also by adjusting the system according to their needs. In the epic software many flow sheets are linked such that if nurse document important orders in one place, they will appear in every relevant flow sheet where those orders are required (Retrieved from http://www.medscape.com/viewarticle/810573). Ð ¼Numerous cases reveal that it is not always easy to manage effective organizational change, thus organizations should find out the possible causes of the failure. There are a lot of changes occurring across the globe. The changes range from increase in competition, changes in customer preferences as well as changes in technology. Organizations are required to create new advantages, serve customers better and cope with stiff competition. To stay competitive, organizations are required to abandon the work and processes that are not fruitful or those that do not add value to the company. As the nurse head I encourage and offer assistance to the nurses who are not used to the epic software (Richards Keogh, 2008).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The epic software has various definite advantages. The system can be made effective by frequent training of the nurses on how to program their flow sheets, the IT department should also ensure that there is enough memory and large server; the institution should also adjust the epic software according to the needs of our patients. I would also propose that the flow sheets should be organized in an appropriate manner; the colors might be used to organize the flow sheets in a superior manner. These options will make the epic system to be user friendly (Richards Keogh, 2008).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In conclusion, change management is very crucial in every institution. The nurses will benefit from various advantages linked to epic software since they will be able to enter their own orders. Computerized charting is better as compared to paper charting. Institutions are called upon to give training and orientation to the nurses so that they can become conversant with this new change. Enough memory and large servers enable the system to be fast and avoid system breakdown. References Charting made incredibly easy! (4th ed.). (2010).

Distinct Serum Protein Pattern in Paranoid Schizophrena

Distinct Serum Protein Pattern in Paranoid Schizophrena A DISTINCT SERUM PROTEIN PATTERN IN PATIENTS WITH PARANOID SCHIZOPHRENIA[A1] N. A. Timofeyeva1,3, I. V. Alekseeva1,3, S. A. Ivanova2,4, G. G. Simutkin2, A. V. Semke2, I. S. Losenkov2, N. A. Bokhan2, O. S. Fedorova1,3, A. A. Chernonosov1,3* 1 Institute of Chemical Biology and Fundamental Medicine SB RAS, Novosibirsk 630090, Russia 2 Mental Health Research Institute, Tomsk National Research Medical Center of the Russian Academy of Sciences, Tomsk, Russia 3 Novosibirsk State University, Novosibirsk, Russia       4 National Research Tomsk Polytechnic University, Tomsk, Russia ABSTRACT The proteomic approach, namely, a combination of 2D gel electrophoresis and matrix-assisted laser desorption ionisation time-of-flight mass spectrometry, is a powerful tool that allows researchers to identify proteins that are differentially expressed in disease states. Schizophrenia is a chronic mental illness, whose aetiology is still unclear; therefore, information about differences in serum protein patterns may improve the understanding of the pathophysiology of schizophrenia. The goal of this study was to use the proteomic approach to identify altered protein levels in the serum samples from patients with schizophrenia. For this study, blood was collected from 10 patients with paranoid schizophrenia and 10 healthy volunteers. We uncovered major changes in the expression of such proteins as apolipoproteins of classes A4 and C3, transthyretin (TTR), and serum amyloid A1. Furthermore, an increase in expression was found only for apolipoprotein A4, whereas the expression of apolipoprotein C3, TTR, and serum amyloid A1 was decreased. The observed differences in the expression of serum proteins (TTR and serum amyloid) are in good agreement with the results obtained by other research groups during analyses of cerebrospinal fluid or post-mortem brain tissues by other methods. Keywords: psychiatric disorder, schizophrenia, [A2]  proteomics, 2D electrophoresis, MALDI-TOF mass spectrometry, biomarker, serum. Introduction Although in recent years, great progress has been made in reducing mortality and in the treatment of common illnesses such as cancer and cardiovascular disease, the mortality caused by mental disorders remains unchanged [1]. Schizophrenia is a chronic mental illness, whose aetiology is still unclear. Schizophrenia is characterised by hallucinations, delusions (positive psychotic symptoms), affective problems [A3](negative psychotic symptoms), and cognitive dysfunction [2]. A number of hypotheses have been proposed about the pathogenesis of schizophrenia, for example, aberrations [A4]  in the pathways of transmission of neurotransmitters dopamine and serotonin [3, 4] or pathological changes in embryonic neurogenesis owing to variations in gene neuregulin-1 [5], as well as oxidative-stress-mediated cell damage due to lowered levels of antioxidant defence enzymes in patients with schizophrenia[A5] [6]. Such pathogenesis may be caused by a dysfunction of some enzymes (proteins) as well as changes of their quantity in the blood of these patients. At the same time, there is no information about differences in serum protein patterns that can be used for typing of psychopathologies among individuals at risk of developing psychiatric disorders [7]. Diagnosis and nosology rely on symptoms and accumulated clinical observations, and thus far, have been based mostly on interviews with patients and on patients subjective complaints [8]. Moreover, current medications still have substantial adverse effects and/or require weeks for therapeutic effects to manifest themselves; not all patients respond to current pharmacotherapy [9]. In sum, an insufficient understanding of psychiatric disorders at the molecular level and the lack of disease-specific changes in serum protein patterns prevent optimisation of diagnosis and treatment of such complex psychiatric disorders as schizophrenia  [A6]. The proteomic approach, namely, the combination of 2D gel electrophoresis and matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS), allows researchers to reliably identify proteins isolated from human bodily fluids [10, 11]. Our exploratory study [12] showed that 2D gel electrophoresis is suitable for isolation of proteins from blood of patients with mental disorders. Therefore  [A7], in the present work, clinical blood samples from patients with a diagnosis of schizophrenia were tested to identify quantitative differences in the proteomic profile of serum. Results and Discussion In this study, we examined blood serum of healthy people and patients with paranoid schizophrenia to search for quantitative and/or qualitative differences in proteins associated with this mental disorder. The use of 2D gel electrophoresis enables researchers to simultaneously isolate more than 300 protein spots on one gel containing 150  µg of protein for subsequent MALDI-TOF MS/MS analysis [10, 11]. We analysed differences in serum protein patterns by comparing the gels between the patients and healthy controls. The analysis [A8]  of protein patterns in serum was focused on those protein spots that differed in 2D gels between the patients and healthy controls. Such protein spots were analysed by means of the Gel-Pro Analyzer software and normalised to the sum of three proteins (a, b, Ñ ; for details, see Materials and Methods). These three proteins are isoforms of apolipoprotein L (ApoL) [18]. As a result, 15 protein spots were isolated and identified by peptide mass fin gerprinting and MS/MS analysis. The list of proteins identified in the NCBI database is shown in table [A9]1. Some proteins haptoglobin, transthyretin (TTR), and apolipoprotein C3 shown in table 1 are present in more than one spot on a gel and have different pI values. Perhaps this phenomenon is due to various post-translational modifications or partial processing. It was found that only the serum level of ApoA4 was increased (1.8-fold) as compared to the control group (figure 1a). Our findings support other [A10]  reports on altered protein levels in serum and cerebrospinal fluid in schizophrenia [19, 20].   Ã‚   The decrease in the serum concentration relative to the control group was observed for ApoC3 and for ApoC2 in patients with schizophrenia (figure 1b). This downregulation was on average from 1.8- to 3-fold for ApoC3, and smaller for ApoC2: only 1.25-fold. These proteins are synthesised in the liver and are components of very low-density lipoproteins (VLDLs). Apolipoprotein C2 activates extrahepatic lipoprotein lipase, whereas apolipoprotein C3 can inhibit lipoprotein lipase Fig. 1 Examples of proteins with differential expression in human serum are presented in the enlarged sections of the 2DE profile. a) Apo A4; b) Apo C3 and C2; c) serum amyloid A1; d) transthyretin (the protein is present in two spots because of post-translational modifications). Sch: schizophrenia. and activate LCAT [21, 22]. Previously, it was found that the expression of apolipoproteins is altered in schizophrenia, bipolar disorder, and other psychiatric disorders [23]. The authors found that low-density lipoproteins (LDLs) and VLDLs are the most prominent factors differentiating depressed patients from healthy controls, and that plasma unsaturated lipid concentrations are elevated in the depressed group. Thus, there is growing evidence that deregulated lipid homeostasis may play a common role in the pathophysiology of psychiatric disorders such as schizophrenia. Other proteins with a decreased concentration are serum amyloid A1 and TTR (figure 1c and 1d). Inflammatory amyloid A1 is among the so-called acute phase proteins, which have both direct and indirect bactericidal and/or bacteriostatic properties. According to the classical theory of inflammation, in the acute phase of inflammation, the serum concentration of amyloid A1 increases 100- to 1000-fold [24], whereas in our study, we observed a 2.3-fold decrease in the serum concentration of this protein in patients with schizophrenia. Perhaps this result  [A11] is due to decreased immunity in Table 1. The list of proteins from human serum analysed by 2DE and identified by MALDI-MS/MS after in-gel digestion with trypsin.

In addition, [A12]  it is possible that a decrease in serum amyloid A1 concentration is related to downregulation of antioxidant-defence enzymes in patients with schizophrenia [6] because high-density lipoproteins (HDLs) inhibit oxidative modification of LDLs via the activity of their associated enzymes and apolipoproteins [25]. If HDLs become so-called dysfunctional HDLs because of accumulation of oxidants derived from an inflammatory reaction, such HDLs inhibit the HDL-associated antioxidant enzymes and reduce the ability of apolipoproteins A1 to promote ABCA-1-mediated cholesterol efflux [25]. In the literature, there are data on a strong positive relation between cholesterol levels and pathophysiological features of mood disorders. The link between mental health (brain) and cholesterol is believed to be based on hypothetical neuron-associated mechanisms. Cholesterol is an integral component of the plasma m embrane of neurons and is present in myelin. Furthermore, cholesterol performs crucial functions in the development, stability, and workings of the synapse [26]. Overall, aberrations in cholesterol in a psychiatric illness may substantially affect the mood via synaptic stability and lowered serotonergic activity. In the case of TTR, we observed a decrease in the serum concentration of its dimer and one of monomeric forms (protein 10 in Table 1) among the patients with schizophrenia (~1.7-fold and ~1.5-fold, respectively), whereas the serum level of another TTR monomeric form was found to be unchanged relative to the control group (protein 9 in Table 1). TTR is a liver-derived secretory protein and is the major serum carrier of thyroid hormones: thyroxine and tri-iodothyronine. TTR is also involved in the transport of retinol via an interaction with retinol-binding proteins. Several studies were conducted in an attempt to identify disease biomarkers that could advance the understanding of the pathogenesis of schizophrenia. In some of these studies, a link between TTR and schizophrenia was found [27, 28]. In ref. [28], it was estimated that 3% of TTR in ventricular cerebrospinal fluid [A13]  and 10% of TTR in lumbar cerebrospinal fluid are derived from blood. To assess the involvement of blood TTR in the changes observed in the cerebrospinal fluid of patients with schizophrenia, those authors also studied serum TTR levels in the same people (simultaneously with cerebrospinal fluid collection) by an ELISA. They observed a significant moderate decrease in TTR concentration in serum samples of patients with schizophrenia compared to co ntrols. Nevertheless, there was no association between cerebrospinal-fluid and serum TTR levels in the same individuals, indicating that the protein levels of TTR are regulated by different systems in serum and in cerebrospinal fluid. Conclusion In the present study, we identified differentially expressed proteins in the serum from patients with schizophrenia by proteomic analysis. We showed differential expression of such proteins as TTR, serum amyloid A1, and apolipoproteins of classes A4 and C3. Furthermore the increase in the expression was found only for apolipoprotein A4, whereas the expression of apolipoprotein C3, TTR, and serum amyloid A1 was decreased. Such alterations of the expression of these proteins may indicate problems with regulation, for example, in the synthesis. On the other hand, the altered protein expression may simply reflect the pathophysiological status of patients with schizophrenia, where these proteins could be candidates for biomarkers.   Nevertheless, to confirm the significance of the altered levels of these proteins in the pathogenesis [A14]  of schizophrenia, and to determine their suitability as biomarkers of schizophrenia, further research is needed.

Social inequality in 1820s Essay examples -- essays papers

Social inequality in 1820s Social equality has been a goal of America since its very beginning. However, it was only an intention to be socially equal, but not a goal. Social equality or the fact that all men were created equal only applied to the white man. There was no intention in meaning that the blacks and Indians or even the women were equal. In the eyes of the delegates, and the common white majority, blacks, indians, and women were not an issue. To them, it was apparent that blacks were kids, Indians were savages, and women were homemakers. From the late 18th century to the mid 19th century was the greatest era of social and racial inequality in all American history. The Declaration of Independence states, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." This infamous passage written by Thomas Jefferson on July 4th, 1776, states that ALL men are created equal and are entitled to Life, Liberty, and the pursuit of Happiness. Although this statement has been argued about its actual meaning hundreds of times by students, philosophers, historians, etc., it still is relevant in discussing the true intentions of the new nation. If all men were created equal then why were there slaves? Why did the government deny the Indians of their rights? Why was there so much injustice? That phrase simply meant that all free citizens were politically equal. This did not apply to blacks or women under the eyes of the signers. As time went by, the meaning "All Men are created equal" took a meaning different t han that of the common people in 1776. The years following the establishment of the new nation were times of refining and tuning of the new government. The question of the true meaning of "All Men are Created Equal" arised again and again until it influenced the minds of Americans that is was time for social equality. In order to understand the reasons why blacks were treated so cruelly and socially unequal is to understand the perspective of whites in the era from the late 18th century to the late 19th century. "It (the south) must pettify the institution and its own reactions, must begin to boast at its own Great Heart. To have heard them talk, indeed, you would have thought the sole reason ... ...m to move in the dead of winter. In other words, the Indians were said to have had rights, but never really had any because the American Government constantly changed the rules because of their lack of respect towards the Indians and their belief that they were inferior. In Conclusion, the period between the late 18th century to the mid 19th century was one of the most socially and racially unequal times in all of AMerican History. The rights described in our Declaration of Independence were irrelevant to minorities, the assumption that "All Men Are Created Equal" was only applied to white men and not minorities like Blacks and Indians. Blacks were treated like children in this period, thought to be inferior and uncivilized and therefore not even rights. Even worse, Indians were promised rights and land, only to have both stripped from them by the American government through means of "treaties", agreements, and war. This period was truly one of the most wrong and unequal periods of American History, however, it was a landmark in the creation of a new nation. While all these social inequalities existed, America flourished and grew to be one of the greatest nations in the world.

A Little Commonwealth Essay -- essays research papers

The modern image of the New England Puritans, as one perceives, is a dark one: the Puritans, religious dissenters who valued propriety and order, are seen as a witch-hunters, suspicious tribe, and their very name carries connotations of grimness and primness.

The Theme of Marriage in Jane Austens Pride And Prejudice Essays

The Theme of Marriage in Jane Austen's Pride And Prejudice One of the main themes in Pride And Prejudice is marriage. Throughout the novel, the author describes the various types of marriages and reasons behind them. "It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife. The novel demonstrates how many women need to marry men they are not in love with simply in order to gain financial security. The first instance of marriage seen in the novel is that between Mr and Mrs Bennet. However it is far from perfect, with the couple barely speaking to each other. Mr Bennet's extreme sarcasm that is seen throughout the book makes Mrs Bennet seem incompetent to hold a conversation and indeed at times a relationship. "They are silly and ignorant, like other girls". Austen uses the Bennet's relationship to illustrate at the beginning of the book that clearly many did not marry because of love or connection but merely for social and financial acceptance. The Longbourn estate is an extreme hardship on the Bennet family; it produces a hurdle in Mrs Bennet's goal to get all of her children married. The entailment of Mr Bennet's estate leaves his daughters in a poor financial situation, which both requires them to marry and makes it more difficult for them to marry. It might be correct in assuming that Mrs Bennet felt social and financial pressure to get all of her children married. Her husband's estate was entailed to his nephew, Mr. Collins. Therefore, Mrs. Bennet wanted her daughters to have financial stability elsewhere in case of their father's death. "If you go on refusing eve... .... Austen creates a character that is not special in any particular way but is yet so perfect to fulfil the role of a wife. We see that she is well dressed, educated, and creative. It is these qualities that attract Darcy as well as Elizabeth's apparent unwillingness to actually marry. Ultimately Elizabeth wants to marry for love. She turns down Mr Collins, even though he could have offered her a comfortable position in life and Mr Darcy, even with his fortune of  £10 000 a year. Austen uses different characters and their relationships to represent to the reader different aspects of marriage. Austen wants to create the perfect marriage but in doing this shows the reader that no marriage is perfect. She highlights how money and social status was far more desirable in the 19th century then true love and appreciation.

Respiratory System Mechanics Essay

1.) When you forcefully exhale your entire expiratory reserve volume, any air remaining in your lungs is called the residual volume (RV). Why is it impossible to further exhale the RV (that is, where is this air volume trapped, and why is it trapped?) This â€Å"dead space† of air needs to stay in your lungs constantly; otherwise the lung will completely deflate. If the lung has every bit of air sucked out of it, it will collapse and need to be re-inflated. 2.) How do you measure a person’s RV in a laboratory? By the air remaining in the lung 3.) Draw a spirogram that depicts a person’s volumes and capacities before and during a significant cough. Additional Questions for Activity 1. The following questions refer to Activity 1: Measuring Respiratory Volumes and Calculating Capacitates 1.) What would be an example of an everyday respiratory event the ERV button Stimulates? forced expiration 2.) What additional skeletal muscles are utilized in an ERV activity? abdominal-wall muscles and the internal intercostal muscles contract 3.) What was the FEV1 (%) at the initial radius of 5.00 mm? 73.9% 4.) What happened to the FEV1 (%) as the radius of the airways decreased? How well did the results compare with your prediction? FEV1 (%) decreased proportionally with the radius 5.) Explain why the results from the experiment suggest that there is an obstructive, rather than a restrictive, pulmonary problem. The FEV1 (%) decreased proportionally as the radius decreased, characteristic of an obstructive pulmonary problem Activity 2 Comparative Spriometry Chart 2: Spirometery Results Patient Type TV (ml) ERV (ml) IRV (ml) RV (ml) FVC (ml) TLC (ml) FEV1 (ml) FEV1 (%) Normal 500 1500 3000 1000 5000 6000 4000 80% Emphysema 500 750 2000 2750 3250 6000 1625 50% Acute asthma attack 300 750 2700 2250 3750 6000 1500 40% Plus inhaler 500 1500 2800 1200 4800 6000 3840 80% Moderate exercise 1875 1125 2000 1000 ND 6000 ND ND Heavy exercise 3650 750 600 1000 ND 6000 ND ND 1.) Why is residual volume (RV) above normal in a patient with emphysema? The lungs empty slower than normal. 2.) Why did the asthmatic patient’s inhaler medication fail to return all volumes and capacities to normal values right away? The smooth muscle in the bronchioles didn’t return to normal plus mucus still blocks the airway. 3.) Looking at the spirograms generated in this activity, state an easy way to determine whether a person’s exercising effort is moderate or heavy. The more rapid the lines the more heavier the exercise. Additional Questions for Activity 2. The following questions refer to Activity 2 Comparative Spirometry 1.) What lung values changed (From those of the normal patient) in the spirogram when the patient with emphysema was selected? Why did these values change as they did? How well did the results compare with your prediction? ERV, IRV, RV, FVC, FEV, and FEV1 (%) all changed; these are due to the loss of elastic recoil 2.) Which of these two parameters changed more for the patient with emphysema, the FVC or the FEV1? FEV1 decreased significantly more 3.) What lung values changed (from those of the normal patient) in the spirogram when the patient experiencing an acute asthma attack was selected? Why did these values change as they did? How well did the results compare with your prediction? TV, ERV, IRV, RV, FVC, FEV1, and FEV1 (%) all changed; due to restriction of the airways 4.) How is having an acute asthma attack similar to having emphysema? How is it different? Similar because obstructive diseases characterized by increased airway resistance; Different because more difficult to exhale with emphysema that with asthma 5.) Describe the effect that the inhaler medication had on the asthmatic patient. Did all the spirogram values return to â€Å"normal†? Why do you think some values did not return all the way to normal? How well did the results compare with your prediction? Returned to normal were TV, ERV, FEV1 (%); smooth muscles in the bronchioles didn’t return to normal blue mucus still blocks the airway 6.) How much of an increase in FEV1 do you think is required to be considered significantly improved by the medication? 10-15% improvement 7.) With moderate aerobic exercise, which changed more from normal breathing, the ERV or the IRV? How well did the results compare with your prediction? IRV changed more with moderate activity 8.) Compare the breathing rates during normal breathing, moderate exercise, and heavy exercise. TV increased over normal breathing with both moderate and heavy exercise. Activity 3. Effect of Surfactant and Intrapleural Pressure on Respiration Chart 3: Effect of Surfactant and Intrapleural Pressure on Respiration Surfactant Intrapleural pressure left (atm) Intrapleural pressure right (atm) Airflow left (ml.min) Airflow right (ml/min) Total Airflow (ml/min) 0 -4 -4 49.69 49.69 99.38 2 -4 -4 69.56 69.56 139.13 4 -4 -4 89.44 89.44 178.88 0 -4 -4 49.64 49.64 99.38 0 0.00 -4 0.00 49.64 49.69 0 0.00 -4 0.00 49.69 49.69 0 -4 -4 49.69 49.69 99.38 1.) Why is normal quiet breathing so difficult for premature infants? They don’t have much surfactant. 2.) Why does a pneumothorax frequently lad to atelectasis? If the lungs are broken down mechanically, then the chances of developing increased. Additional Questions for Activity 3 The following questions refer to Activity 3: Effect of Surfactant and Intrapleural Pressure on Respiration 1.) What effect does the addition of surfactant have on the airflow? How well did the results compare with your prediction? AIrflow increases because resistance is reduced 2.) Why does surfactant affect airflow in this manner? It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. 3.) What effect did opening the valve on the left lung? Why does this happen? The lung collapses because the pressure in the pleural cavity was less than the intrapulmonary pressure; air flows from the lungs, causing it to collapse 4.) What effect on the collapsed lung in the left side of the glass bell jar did you observe when you closed the valve? How well did the results compare with your prediction? It caused the lung to collapse because the pressure in the pleural cavity is less than the intrapulmonary pressure. Air flows from the lungs causing the collapse of the lung. 5.) What emergency medical condition does opening the left valve simulate? A collapsed lung (pneumothorax) is a buildup of air in the space between the lung and the chest wall (pleural space). As the amount of air in this space increases, the pressure against the lung causes the lung to collapse 6.) In the last part of the activity, you clicked the Reset button to draw the air out of the intrapleural space and return the lung to its normal resting condition. What emergency procedure would be used to achieve this result if these were the lungs in a living person? A chest by insertion of tube to draw air out of pleural cavity and restore the pressure gradient 7.) What do you think would happen when the valve is opened if the two lungs were in a single large cavity rather than separate cavities? If both lung were in a single large cavity rather than separate cavity when valve was open the entire lung will collapse and there will be no extra lung to breath with and death would occur much sooner.
