Music Therapy for Autistic Children Essay -- Health, Treatment

II. History of Music Therapy Music Therapy originated in treatment hospitals for World War II Veterans. The doctors and hospital staff realized that the musicians needed training to interact with the patients. They originally had just played music in the hospitals around the patients and did not have any training other than their music training. These realizations lead to the creation of the first college degree program for Music Therapy at Michigan State University (A-9). Music Therapy is now used in many different venues, from children to Alzheimer’s Patients (N-2). According to the American Music Therapy Association â€Å"Music Therapy interventions can be designed to: Promote wellness, manage stress, alleviate pain, express feelings, enhance memory, improved communication, and promote physical rehabilitation† (D-1). They also state that any types of music can be used for therapy and therapy can be used on any types of people including people with not existing medical conditions (N-4). A News Paper Article in New Jersey even states that Music Therapy has uses for anything from birth to adults (J-1). The AMTA States that â€Å"Music Therapy is the clinical and evidence-based use of music interventions to accomplish individualized goals within a therapeutic relationship by a credentialed professional who has completed an approved music therapy program† (D-2). Therapists are available through schools. They also have private pract ices. Depending on the state, there may be state funding for the programs (A-4). When a Therapist works with a child they began planning a treatment. This happens before any treatment is done as well as during the treatment process. They reevaluate during the treatment process to make sure that the treatment... ...n they see that they can do something, they are motivated both within the session and outside of the session (F-1). Research has shown that extemporaneous music attracts ADS children’s attention more than pre-recorded music (F-4). Children are surrounded by instruments throughout their therapy session and they learn about all of them because they are surrounded by them. They can even talk about the instruments outside of the Music Therapy Sessions (K-3). One Mother testifies that â€Å"Perhaps the best part is the carry-over effect† (K-4). X. What does not work When the Tomatis sound method, it was found to not work as well at music therapy (G-1). The research that has been done on Music therapy has been done mainly outside of the USA. The places include Turkey, Denmark, and many others. As of 2000 there were no controlled music therapy research being done (G-2).

History of the game Essay

As the rackets of the game have changed, the style of play has changed accordingly. During the wooden racket era, before the flood of the metal and metal composite rackets, players hit groundstrokes with slight topspin but mostly flat or with underspin, particularly on the backhand side. To provide the players with the underspin or flat shots, players hit with an eastern grip (slightly east of the continental style grip achieved by sliding the â€Å"V† area between the thumb and index finger down the side of the frame to the grip) to help generate slice and handle low balls better. Players used this style of play to compensate for the lower bounce produced on grass courts compared to the bounce of hard and clay courts today. In effect, groundstrokes had to be long and fluid with early preparation and a long follow through to get the necessary power and control by swinging the heavier wooden rackets.  Players with wooden rackets also stood sideways to the ball and stepped into the swing to generate more power. Furthermore, the small sweetspot of the wooden racket required players to have more exact, controlled swings instead of the quick, powerful, whip-like swings of today’s players. As an example, John McEnroe, a former tennis professional and Grand Slam winner, supports wooden rackets saying: I have been a proponent of the wood racket†¦wood rackets would bring back skill and finesse to the game and would make the points longer and more fun to watch. And I could watch all those young guys cry like that little baby doll that wets herself as they try to return a serve with a 15-ounce piece of lumber. (McEnroe 1).  As a result, players could not end the point with a single shot like today and therefore games consisted of more rallies. The rackets and styles of play have evolved to the 21st Century and have dramatically changed the way tennis is played. Instead of the long and fluid groundstrokes used with wooden rackets, lighter more powerful rackets have developed quick, short but powerful swings by tennis players today. The players also use a more western or semi-western grip (achieved by placing the racket on the ground and coming from straight above, picking the racket up with one hand). These grips tend to generate more power and topspin as well make it easier to hit high bouncing balls. This heavy topspin usually causes points to end more quickly with more winners and harder shots. These changes in the game are all in relation to the development of higher bouncing courts, hard courts and clay courts, and the shorter grass court tournament season. Also, as a result to the more powerful modern rackets, serves were consistently hit over 100 mph and many clocked at more than 120 mph contributing to the quicker points. Furthermore, many serves were unreturnable meaning that it would be almost impossible for players to return or even more to hit the ball with the racket. The change in rackets in the 20th Century was not only limited to a change in the game but the tennis market was affected as well. According to Edward Tenner, the new rackets were not as profitable for racket manufacturers as the wooden rackets were during the peak in tennis popularity in the early 1970’s (Tenner 3). However, shortly following this rapid growth in tennis popularity, tennis’s popularity among the common people started to decline. According to the records of the Tennis Industry Association, two years before the introduction of the Prince racket in 1974, the number of tennis players reached its peak and then started a decline (Tenner 1). Later, the sale of tennis balls was evaluated and showed a drop in tennis ball usage between 1990 and 1993 (Tenner 3). A short explanation of this event could be that players were not ready to pay the higher price for newer metal rackets. The modern rackets, costing about $150, were much more expensive compared to the lower price of wooden rackets in the early 1970s. However, the introduction of the modern rackets produced a larger selection of varying rackets for tennis consumers shown in the following excerpt from Tennis Magazine, â€Å"To play your best tennis, your racket has to complement your game. And with more frames than ever being designed for specific types of players, finding that magic wand has never been easier.† (2001 Racket Guide 1) In addition, modern rackets are designed for all different types of players including strictly baseliners to serve and volleyers. Mark Macky, Dunlop’s director of racket sports, shows this in the following statement, â€Å"It’s no longer enough to make a racket for one ability level – beginner, intermediate, advanced. Today, companies make rackets that are targeted to specific styles of play. A serve and volleyer, for example, will want a different type of racket than a baseliner.† (2001 Racket Guide 1) Although while racket manufacturers may have suffered from the introduction of modern rackets, consumers seem to benefit. According to â€Å"New York Times† newspaper, the new metal rackets prove to last longer and need restringing less often saving consumers money (Tenner 3). Furthermore, metal rackets can last up to ten years or more contrary to the wooden rackets that were damaged by age, warping, and cracking.  In conclusion, although many tennis professionals believe that wooden rackets would increase the charisma of tennis, there is undeniable evidence that proves modern rackets to be better for the game and all levels of players. Newer rackets provide more options for tennis players, giving them more power and control than ever before therefore elevating the level of play in the game of tennis. They also appeal to lower levels of players making the game easier to learn and in effect, better for everyone. In addition, although the market seemed to be falling, it is currently rising for the game of tennis and showing this, the U.S. Open has had more viewers in the year of 2001 than ever before in the history of the game.

In Things Fall Apart the novel, Okonkwo was determined to be nothing like his father Unoka, this â€Å"strict adherence to masculine standards, (which causes the destruction of his family, creates dissent in his tribe, and leads him to his death) supports the value of the feminine in Igbo culture.† â€Å"Though it may seem that women are seen as the weaker sex in Ibgo society,† (E., Skwiot personal comment, August 23, 2016) The novel is set at the end of the twentieth century.

Drafted two months after the founding of the Council of Europe, in the aftermath of the atrocities of World War II, it was fundamental to the future and stability of the region to introduce Human Rights in a document able to bring peace, unity and accountability. This was articulated at the conference of the International Committee of the Movements for European Unity where the delegates stated: We desire a Charter of Human Rights guaranteeing liberty of thought, assembly and expression as well as the right to form political opposition; we desire a Court of Justice with adequate sanctions for the implementation of this charter.

It also incorporates considerations for how countertransference, Secondary Traumatic Stress, Vicarious Posttraumatic Growth, and compassion satisfaction may either complicate or enhance effectiveness. The conclusion suggests mitigating factors for concerns which could impede effectiveness matched to my needs.

There are no â€Å"second chances,† meaning that if you make mistakes in this life, you cannot make them up in another life. Then in the second sentence, â€Å"Any good things, therefore, that I can do, any good kindness that I can show a fellow being, let me do it now,† states that any good thing that you can do to others, do it now. Do not delay in doing good, because you never know when your time will come. As a Catholic, Grellet believed in life after death, and to get into heaven, one must have lived a good life. You must not pass opportunities because those opportunities will not be there forever. In the third and final sentence, â€Å"Let me not defer or neglect it, for I shall not pass this way again,† it states again that you should not ignore an opportunity to do good and emphasizes once more that â€Å"I shall not pass this way again.

It was Aesop that said â€Å"No act of kindness, no matter how small, is ever wasted,† and Mother Teresa said â€Å"Kind words can be short and easy to speak, but their echoes are truly endless. † Kind acts are never a waste, even if it takes your attention off of material things like money and fortune.

I agree, and I think everyone else agrees, that if an opportunity to do good is presented right in front of you, you would do it. You should not ignore or neglect an opportunity for it might not happen again. And because we only have one life to live, the acts we commit cannot be solved in another life. This is the only life we have, and we should use it to help others and to share our goodness. â€Å"I Shall not Pass this Way Again†: I expect to pass through this world but once.

Tg-BRAF transgenic mice Essay Example

Tg-BRAF transgenic mice Essay Molecular dissection of papillose thyroid malignant neoplastic disease patterned advance to ill differentiated carcinoma in Tg-BRAF transgenic mice: Evidence for epithelial-mesenchymal passage and designation of campaigner tracts. Abstraction Mice ( Tg-BRAF ) with thyroid-specific look of oncogenic BRAF ( BRAFV600E ) develop papillose thyroid malignant neoplastic diseases ( PTC ) by 3 hebdomads of age. At 5 months gt ; 90 % of PTCs are locally invasive, and ~50 % have well-defined focal point of ill differentiated carcinoma ( PDTC ) . To look into the PTC-PDTC patterned advance in Tg-BRAF mice, we performed a microarray analysis utilizing RNA prepared from cells collected by optical maser gaining control microdissection from mated samples of PDTC and well-differentiated PTC from the same animate being. Analysis of 8 mated samples hybridized to a Operon microarray with a 35473 oligo denseness found 98 cistrons with consistent look alterations between PTC and PDTC in at least 7 of the 8 paired samples. EASE analysis indicated that cistrons involved in cell adhesion and intracellular junctions were significantly represented, with alterations consistent with an epithelial-mesenchymal passage ( EMT ) . Decreased look of E-cad herin and desmocollin 2 and increased look of procollagen and vimentin, all of which are trademarks of EMT, were observed in at least 7 of 8 PDTC focal point. The upregulation of vimentin in PDTC focal point was confirmed by IHC. There were no consistent look alterations in LEF/TCF or in the snail household, proposing that the Wnt and sonic porcupine tracts are non involved in the initiation of EMT, or in patterned advance to PDTC. By contrast, increased look of PDGF-B and/or D was found in all 8 PDTC focal point. As TGF?I look is increased in the thyroids of the Tg-BRAF mice, these informations are consistent with a function for a TGF?-activated autocrine cringle affecting PDGF in EMT. Decreased E-cadherin has besides been observed in human BRAFV600E positive anaplastic carcinomas, proposing that thyroid malignant neoplastic disease patterned advance in worlds may besides affect EMT. Pathways modulating this passage may be of biological and curative involvement. Introduction The BRAFT1799A mutant is the most common familial alteration in PTC. It is non found in any other signifier of well-differentiated follicular tumor ( 1 ) . BRAF mutants can happen early in development of PTC, as they are present in microscopic PTCs ( 2 ) . Most ( 2,3 ) , but non all ( 4 ) , surveies show that PTCs with BRAF mutants present more frequently with extrathyroidal invasion and at a more advanced phase. Tall cell discrepancy PTCs, regarded as more aggressive, have a really high prevalence of BRAF mutant ( 2 ) . Undifferentiated or anaplastic carcinomas originating from preexisting PTCs have a important prevalence of BRAF mutants, whereas those originating from preexisting follicular carcinoma do non ( 2,5 ) . These informations show that BRAF mutants may be an alternate tumor-initiating event in PTC, and that PTCs with this genotype probably carry a worse forecast. The function of oncogenic BRAF as a tumor-initiating event has been confirmed in mice with overexpression of B -RafV600E targeted to thyroid cells by agencies of the thyroglobulin ( Tg ) cistron booster ( 6 ) . Tg-BRAFV600E mice develop PTCs with high penetrance early in life, and advancement to dedifferentiation, capsular and microvascular invasion, corroborating many of the characteristics found in the human tumours.

Mice were house in. All described processs were approved by the institutional carnal commission. Thyroid aggregation and optical maser gaining control. Animals were euthanized with CO2 and thyroids collected and instantly frozen in OTC. Frozen subdivisions were stained with H A ; E and examined by diagnostician ( YN ) for WD and PD malignant neoplastic disease. Twelve consecutive subdivisions ( 7.5 millimeter ) were taken from parts found to hold a PD focal point. The consecutive subdivisions were stained with HistoGeneTM LCM Frozen Section Staining Kit ( Arcturus Bioscience, Inc. , Mountain View, CA ) and cells from PD focal point and a representative part of WD malignant neoplastic disease were isolated utilizing the artsus Arcturus PixCell II optical maser gaining control microscope System. RNA was isolated from the optical maser captured cells utilizing PicoPureTM RNA Isolation Kit Kit ( Arcturus Bioscience, Inc. , Mountain View, CA ) and so subjected to 2 unit of ammunition messenger RNA elaboration utilizing the messageAMP RNA elaboration kit ( Ambion, Austin, TX ) . Microarray analysis. The mouse 70-mer oligonucleotide library version? ? ? consists of? ? ? optimized oligos ( Qiagen ) and was arrayed and printed as antecedently outlined. The complete cistron lists can be viewed at? ? ? . Fluorescence-labeled complementary DNA were synthesized from amplied RNA utilizing an indirect amino allyl labeling method via an oligo ( dT ) -primed, change by reversal RNA polymerase reaction. The complementary DNA were labeledAmplified RNA was with monofunctional reactive cyanine-3 and cyanine-5 dyes ( Cy3 and Cy5 ; Amersham, Piscataway, NJ ) . Pairwise hybridisations were done between labeled complementary DNA matching to unstimulated versus doxycycline-treated cells for each of the cell lines and clip points. In add-on, to increase the statistical power of the experiment, paired hybridisations were done to compare look between cell lines at the same clip points before or after oncoprotein activation. Detailss of hybridisation and rinsing conditions can be found at? ? ? . Imagin g and informations coevals were carried out utilizing a GenePix 4000A and GenePix 4000B ( Axon Instruments, Union City, CA ) and associated package from Axon Instruments, Inc. ( Foster City, CA ) . The microarray slides were scanned with double optical masers with wavelength frequences to excite Cy3 and Cy5 fluorescence emittance. Images were captured in JPEG and TIFF files, and DNA musca volitanss were captured by the adaptative circle cleavage method. Information extraction for a given topographic point is based on the average value for the signal pels minus the average value for the background pels to bring forth a cistron set informations file for all the DNA musca volitanss. The Cy3 and Cy5 fluorescence signal strengths were normalized. Data standardization was done in two stairss for each microarray individually ( 19-21 ) . First, background-adjusted strengths were log transformed, and the differences ( R ) and norms ( A ) of logtransformed values were calculated as R = log2 ( X1 ) log2 ( X2 ) and A = [ log2 ( X1 ) + log2 ( X2 ) ] / 2, where X1 and X2 denote the Cy5 and Cy3 strengths after deducting local backgrounds, severally. Second, informations focus was done by suiting the array-specific local arrested development theoretical account of R as a map of A. The difference between the ascertained log-ratio and the corresponding fitted value represented the normalized log-transformed cistron look ratio. The statistical analysis was done for each cistron individually by suiting a mixed-effects additive theoretical account. Premises about theoretical account variables are the same as described in mention ( 7 ) , with array effects assumed to be random and intervention and dye effects assumed to be fixed. Statistical significance of differential look was assessed by ciphering Ps and seting for multiple hypotheses proving by ciphering false find rates ( 8 ) . Estimates of fold alteration were besides calculated. Data standardization and statistical analyses were done utilizing SAS statistical package bundle ( SAS Institute, Inc. , Cary, NC ) . Gene note was supplemented with human and mouse homologues for unknown oligos. Immunohistochemistry: Animals were euthanized with CO2 and thyroids collected and instantly placed in 4 % PFA. After 24 hours they thyroids were placed in 70 % ethyl alcohol and embedded in. ? ? ? was? . Consecutive subdivisions from part found to incorporate a PD focal point were? ? ? and incubated with indicated antidbodies. Immunoreactive was detected by incubating with and? Consequence Gene look profile of WD and PD thyroid malignant neoplastic diseases from Tg-BRAF mice: Tg-BRAF2 mice develop PTC by 3 hebdomads of age and by 12 hebdomads of the animate beings had locally invasive PTC and about 50 % had focal countries of PDTC ( 6 ) . The PDTC were identified by a solid growing pattern incorporating fusiform cells ( Fig 1A ) . Extra verification that the focal point were PDTC was provided by an increased figure of mitotic ( Fig 1B ) and Ki67 positive cells ( Fig 1C ) every bit good as the presence of necrotic/apoptosis cells ( Fig 1C ) . To place cistron look alterations involved in the passage from the WD PTC to the PDTC we used LCM to insulate cells from from 8 alone ill differentiated focal point and a representative country of WD PTC from the same Tg-BRAF2 mice. RNA was isolated from the optical maser captured cells, amplified, labeled with Cy5 or Cy3 and hybridized to operon? ? ? bit. This identified? ? ? cistrons with important look alterations ( P lt ; 0.05 , FDR lt ; 0.1 ) and of these? ? ? had an look alterations that was greater 1.5 crease. There were? ? ? cistrons merchandises that decreased and? ? ? that increased. To place signaling tracts that may intercede or lend to these look changes we used EASE analysis to compare our informations set to the Gene Ontology and KEGG databases. This found that cistrons involved in tight junction, ? ? and where significantly represented in the PDTC information set. Closer scrutiny indicated that that cistrons involved in tight juntction and cell contact were decreased, while the intermediate filament cistron increased in look ( Table 2 ) . These alterations are consistent with an EMT. To corroborate cells in the PDTC had undergone EMT a 2nd set of thyroids from Tg-BRAF2 animate being were IHC stained for E-cadherin and vimentin, hall Markss of EMT. tracts Mentions 1.
