Essay on Parkinsons Disease and Tissue Transplants

For nearly 100 years neural tissue has been transplanted in animals. Transplantation of neural tissue into humans, however, began only a few years ago (1). It has been found in animals, that fetal brain grafts in damaged adult host brains reduce some of the functional deficits caused by brain lesions. Even though some neurons from the transplanted tissue survive and develop reciprocal connections with host brain tissue, this is not enough to completely replace damaged fibers and support behavioral recovery Usually the grafts will not develop a normal morphological appearance, but some metabolic activity can be found within the transplant. Release and diffusion of trophic substances from the transplant and the damaged host brain may†¦show more content†¦Furthermore, adrenal medullary transplants have proved to be only minimally effective (4). Fetal brain transplants have been more successful in animal and human studies, but ethical concerns have been raised. An alternative method using genetically engineered fibroblasts has been introduced. Although the fibroblasts may be used as a source of trophic factors or hormones, they lack neuronal properties that may be important in future development of neural transplants. A new technique has been devised to overcome these limitations: transplantation with temperature-sensitive immortalized clonal neural cells (4). One example of this system was to use primary rat central nervous system cells immortalized with a temperature-sensitive Rous Sarcoma virus, cloned, and previously analyzed for neural and glial characteristics. The cells were not permissive for replication of the avian virus, however, expression of the viral genes did occur. The cells were transformed and immortalized at 34 °C but differentiated at 38 °C. Along with differentiation came a halt in cell division, extension of neurites, and the appearance of developmentally regulated molecules such as neural cell adhesion molecule (N-CAL1) and the cellular isoform of a prion protein (4). There would be many theoretical advantages to a temperature- sensitive cell system. There would be unlimited availability of cells and application to any transmitter system.Show MoreRelatedA Research Study On Stem Cell Therapy1450 Words   |  6 Pageshuman race.

My intended audience will be high school and college students who have somewhat of an interest in fashion, and also want to make their daily lives easier and more productive. I start off my blog post by asking the readers a question and making a statement that they would think is not true.

Discuss in detail the Fugue from Bach Essay Example For Students

Discuss in detail the Fugue from Bach Essay To live is to suffer. 1 Spitta claims that this idea is persistent throughout the b minor fugue no. 24 from Bachs Well-Tempered Clavier Book 1 and that it was Bachs purpose to produce a picture of human misery. 2 By looking at this fugue, particularly Bachs use of subject and counter-subject, this essay will aim to discover how justified Spittas opinions are. The direction Largo is Bachs own and comparing it to the other fugues in the Tovey edition, this fugue is unique in being given such a direction by the composer himself. 3 The emotion poured into its composition may have been why Bach felt a performance direction meaning slowly and stately was necessary. 4 The fugue is the longest in the book perhaps because it was the final piece in the book, possibly because b minor was, according to Spitta, Bachs favourite key, but more likely in order to convey suffering and misery effectively. 5 The subject shown in figure 1 contains all twelve notes of the chromatic scale and is described by Spitta as sighing, saddened and pain stricken. 6 Upon listening to it there is a general feeling of unease. The six pairs of quavers, slurring the interval of a minor second are described by Keller as a sigh-motive. 7 Each pair gives the listener a feel of resolution but followed by immediate continuation, building up tension in the subject alone and as a whole the subject depicts the feeling of misery to the listener. The subject and its tonal answer both enter in full a number of times. In order to increase tension further Bach uses small fragments of the subject, teasing the listener into thinking that the subject has returned but then cutting it short. This further enhances the idea of suffering and misery. Figure 2 shows this used on two separate occasions when only the first three notes of the subject are heard. These notes give a feeling of foreboding and sound sombre against the light, bouncy, sequential patterns of the first episode that precede and follow it. This device is also used in the only complete stretto passage of the piece shown in figure 3. 8 Bach uses the first 9 notes of the subject in the first 3 entries and then finally the subject in full. It begins in the soprano in b. 41 followed by the alto in b. 42 then bass in b. 43 and finally in b. 44 the full subject begins in the tenor. This stretto builds tension through its use of repetition. The counter-subject in this fugue is quite difficult to categorise. In his analysis, Iliffe categorises the counter-subject as beginning on the second note of b. 4 to the first not of b. 7. 9 As the fugue progresses, however, the counter-subject is broken up into various segments which are used in different voices, in varying orders and in inversion. Kellers analysis of the counter-subject is shown in figure 4 and is preferable as it breaks it down into a bridge (a), the counter-subject (b) and a continuation passage (c). 10 The counter-subject in particular is the chief cause of discords and Keller says it has relentless harshness further adding to the misery and suffering depicted in the piece. 11 Bachs manipulation of the counter-subject is another analogy to life. Things are not always as expected and Bach plays with convention. He uses motifs from the counter subject in the third voice shown in figure 5. Firstly the bridge section is sounded in inversion (a) and then Bach inverts the first three notes of the counter subject (b). The sequences between bars 17 21 are classed, by Iliffe, as the first episode, but form part of an extended exposition. .u7cb2cc845e95c9e146486b8e2ecf5d7c , .u7cb2cc845e95c9e146486b8e2ecf5d7c .postImageUrl , .u7cb2cc845e95c9e146486b8e2ecf5d7c .centered-text-area { min-height: 80px; position: relative; } .u7cb2cc845e95c9e146486b8e2ecf5d7c , .u7cb2cc845e95c9e146486b8e2ecf5d7c:hover , .u7cb2cc845e95c9e146486b8e2ecf5d7c:visited , .u7cb2cc845e95c9e146486b8e2ecf5d7c:active { border:0!important; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .clearfix:after { content: ""; display: table; clear: both; } .u7cb2cc845e95c9e146486b8e2ecf5d7c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u7cb2cc845e95c9e146486b8e2ecf5d7c:active , .u7cb2cc845e95c9e146486b8e2ecf5d7c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .centered-text-area { width: 100%; position: relative ; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u7cb2cc845e95c9e146486b8e2ecf5d7c:hover .ctaButton { background-color: #34495E!important; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u7cb2cc845e95c9e146486b8e2ecf5d7c .u7cb2cc845e95c9e146486b8e2ecf5d7c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u7cb2cc845e95c9e146486b8e2ecf5d7c:after { content: ""; display: block; clear: both; } READ: Chaucer Used Poetic Form EssayTypically the first episode of a fugue marks the start of the development but here, to prolong the suffering, Bach stays in the tonic and a redundant entry of the subject in b. 21 completes the exposition. 12 Splitting the counter-subject up and tricking the listener by extending the exposition means the fugue never sounds resolved until its end. This makes the fugue unique listening when compared to the others in the book. Although beautiful to listen to this unrelenting continuation is in a way suffering for the listener until the fugue ends. This can be likened to the way Bach viewed life as constant suffering. There are some wonderful but frustrating moments in the fugue where the listener expects a resolution but the fugue just continues. In figure 6 the exposition is coming to an end and as the first chord of b. 24 is sounded the listener can almost breathe a sigh of relief at the sound of a perfect cadence. Bach doesnt allow this to last long though as the second episode continues on the next semi-quaver and the exposition is complete, the listener barely having time to take in what has been heard previously in much the same way that life continues relentlessly. From the examples shown it is clear that Spittas opinions are valid. A uniquely chromatic subject with unusual minor second intervals creates the human misery. The use of three counter-subject motifs in different voices, inversions and orders mean the listener, as in life, never knows what to expect. The exposition and suffering is extended by including the first episode within it and following it with a redundant entry of the subject in the tonic. Being the only fugue which the composer added a tempo and expressive marking to Bach clearly felt strongly about its content and impact on the listener. The fugue being in his favourite key can only have helped Bach create such strong emotive qualities, really express misery through music and convey the idea that to live is to suffer.
