The impact of Social Media on academic life In this report we will be discussing a whole range of topics on how social media has had a massive impact on academic skills. The reason why we choose this as a group is because we all know how big social media and also social networking sites has had a massive impact on us and also a lot of people not just youngster but adult as well so this research/project really fits in our age democrat and our day to day lifestyle. We split the research and presentation evenly so between the three of us know one had too much to do or too little to do. As a trio I believe we worked well as a team even though we only knew each other’s couple weeks prior the group research was given out. No matter what people do everybody socialise with different people whether if it’s on the phone, computer, work, school, colleges and even universities. What we really want to know is why it has a massive affect on people’s academic life, seeing as people mostly use social media networking sit es to communicate with family members and friends. The issues that will be discussing in this report will be: †¢ What is social media †¢ History on how social media expanded †¢ Several different types of social media †¢ Advantages of social media on academic life †¢ Disadvantages of social media on academic life †¢ Our view on social media on a whole and conclusion What is social media? Social media is interacting with people using the internet. Having varies of social channels, websites that allows you to blog communicate, upload pictures and videos are all different types of social media. This allows you to share information with one another. Social media is increased throughout the years, every other month and new social media ... ...attending our meetings or lessons we will let the teacher know and also deal with the matter ourselves. This risk assessment shows what we have planned for any risk that may accrue while doing our project. We also showed what and how we would handle them as a team. Few of the risks above did occur to us which is what we put it in our risk assessment. References Dave Kerpen (June 7th 2011).

The Idea Of Universal Design Architecture Essay

There are many misconceptions environing the thought of cosmopolitan design. Peoples frequently believe that supplying the handicapped with signage or a incline is sufficient and patterns the ideals of cosmopolitan design. What people must understand is that cosmopolitan design is about supplying these necessary comfortss to the disabled without segregating them from the norm of society. It is besides approximately making a infinite that can defy multiple environments and the crazes of clip as a dateless creative activity. In a universally designed universe peoples differences are non highlighted by constructing use but are designed for and make seamlessness between users. The bottom up theory is looked to by many interior decorators when set uping cosmopolitan infinite ; â€Å" it works on the premiss that the edifice users, the designer is functioning include those with disablements are all people who can be treated as normal people [ 2 ] † and with this you must get down at the underside of the pyramid and purpose to make the top and achieve universal design. Questions to see when planing a universally designed infinite may be how this infinite will react to different environments or epochs and as the user or users change what will be the response to how it is used. Universal designed has been outlined and defined into seven rules that can be applied to a broad scope of countries including architectural infinites to merchandise design.Equitable usageFlexibility in usageSimple and intuitivePerceptible informationTolerance for mistakeLow physical attemptSize and infinite for attack and usageAccess Living HeadquartersAccess Living is an organisation that started in the early 1970 ‘s and has been committed to rehabilitation and growing of handicapped peoples by the support of handicapped peoples. This company has personal with a battalion of disablements and alone challenges that they encounter. In March 5, 2007 LCM Architects lead by spouse John H. Catlin, FAIA designed entree life ‘s chief central office in Chicago with non merely a cosmopolitan focal point by as a sustainable design way. This 50,000 115 West Chicago Avenue. concern footmark for Access populating genuinely reflects the mission of the company and reinforces their ideals to authorise the options available to differences of others. It has been awarded â€Å" the Barrier Free America Award from Paralyzed Veterans of America ; A sustainable design award from AIA ; the Trend Setter Award from Friends of Downtown ; LEED Gold Certification ; and a Silver Award from the Association of Accredited Architects † .Design Solutionsâ€Å" LCM designers started the vision of cosmopolitan design, by taking an accessible location † and sing edifice attack. The edifice is no more than two blocks from the local train ‘s belowground station and from the metropolis coach. This close relationship non merely encourages green transit but it provided for utilizations that may non hold other manners of transit and its premier location allows for people from multiple locations to be able to utile this characteristic with easiness. In add-on to the consideration of close propinquity, the garage of the edifice has designated infinites that allow for electri c vehicles to be recharged for usage. As users approach, the edifice integrates two kerb bead offs seamlessly added to let for users coming from street degree and for wheelchair lifts to hold a â€Å" direct path to the chief edifice entryway † [ 4 ] . Being in a colder clime of the United States, architect Catlin devised a solution to cover with iced pavements in the winter months by planing a het concrete pavements and good illuminated attacks. All of these characteristics lead straight into the entryway of the edifice that is separated by two sets of skiding doors that open straight off the pavement. These doors have a broad gap of 60 inches to let for easy mobility or two wheelchairs in passing. Once you enter in to edifice for entree life, its good designed interior anteroom infinite and furniture choice leaves you no hint that this infinite is universally designed. LCM designers and there squad of interior decorators took close consideration into their interior picks being scruples of spacing, stuffs, colourss and constellations so this truly was a universally accepting infinite. â€Å" Universal design has a close relationship to human factor and biotechnologies. As a procedure they both attempt to see the abilities and restrictions of users when developing a merchandise or edifice an environment. [ 5 ] † All of the furniture came from the Steelcase, so a choice piece could be duplicated in several signifiers to include with arms/without, adjustable or basic systems that encouraged alteration as necessary. Using a individual maker line allowed for a broad scope of siting picks to read and flux seamlessly. Within this constellation ample infinite is giving for wheel chair move ability and integrating within a personal or big group interaction. Multiple chair highs are included for users of all statures and â€Å" clearance below some of the seating is unfastened to let the user to force up to the standing place with their leg musculuss [ 6 ] † . A usage characteristic within the anteroom is the response desk ; â€Å" Lehner points out that the response country underscores the cosmopolitan design. â€Å" â€Å" A individual nearing the response desk in a wheelchair should hold the same ability to utilize it as a individual who does n't hold a disablement. That ‘s the premiss behind the full design-no 1 uses a back door or side door, and no 1 uses a incline. Everybody comes in the same door and uses the same lifts † † [ 8 ] . Unique to most response desk, the primary dimension is at a wheel chaired accessible â€Å" antagonistic tallness of ( 29-30 † AFF ) † [ 9 ] . Based on the guided attack to the desk articulatio genus and toe infinite is carefully designed and supply for. The response desk does besides include a little part at the standard tallness of 42. Much consideration was giving to the response side of the desk because this would be the primary and full clip user of the millwork. The desk maintains the counter tallness and electrical mercantile establishments are placed at the terminals of the counter opposed to across to minimise the demand for users to strive to make across counter span. The employee besides is provided with a really accessible attack to their work station and a turning radius within, leting for a 360 grade wheelchair turning radius. Beyond the response desk, cagey inclusions of cosmopolitan rules are utilised to help with user move ability throughout. Two lifts with dual entry points allow users to travel rapidly in and out without the demand of turning within a little confined infinite. The lifts are besides big plenty to back up four wheelchairs within. Along with the maximization of mobility within the lift Architect Catilin incorporated province of the art exigency usage engineering for the deaf and caput of hearing and enlarge lift buttons placed at a cosmopolitan accessible tallness. Each of the floors of the Access Living Company, are colour coded so users can easy place vicinity and way. This colour coding procedure is a fantastic tool to help the immature kid to aged and people with all timers. This would besides extinguish the defeats of acquiring off the lift on the incorrect floor, like so many of us have done. Once on a floor users, will detect ample floor infinite as to non to experience constraine d by close furniture constellations and for wheelchair passing. The high traffic and countries of emersion are ingeniously deigned with a floor boundary line that lines the walls so the visually impaired can easy use this tool to steer through the floors. To a user with no sight impairments this merely appears as an aesthetical characteristic because of how good it integrated throughout. This characteristic is a premier illustration of how cosmopolitan design rules do non foregrounding the differences of users.ObstaclesIn planing the Access Living headquarter LCM Architects, incurred many obstructions in making a infinite that was non merely cosmopolitan, sustainable but besides aesthetically and functionally functional. With their primary focal point on making a cosmopolitan infinite they rapidly learned that â€Å" what works for one disablement does n't ever work for another, [ 10 ] † Lehner says. As a cosmopolitan interior decorator you must larn to equilibrate the integrating of adjustments so they are non swayed by a peculiar user. à ¢â‚¬Å" That ‘s nowhere more evident than in the flooring. Lowest common multiple discovered through research that rug, contrary to popular belief, serves people with MCS by pin downing contaminations that would otherwise remain airborne. It besides offers grip for people utilizing canes. â€Å" But rug can be hard to negociate with a wheelchair, † says Catlin [ 11 ] † This is a great lesson to be learned because when people think a disablement they excessively frequently merely think of wheelchair users. After choosing a cloth that architect Catlin thought would be perfect for all of the users in the infinite he rapidly had to return to the pulling board after one employee had an epileptic ictus from the intense patterning of the flooring. This is one illustration of the many troubles faced in this undertaking in planing for the multitudes, but Catlin remedies this job by put ining a more hushed form through the edifice while still â€Å" guaranting at that place was still adequate contrast on hallway boundary lines to assist steer people with ocular damages [ 12 ] † .DecisionAlthough they are a part of users there are wheel chair bound we must see and be cognizant that there are infinite damages that cause all users to hold different demands and ways in which they utilize a infinite. Planing a cosmopolitan infinite you must hold an apprehension of that and retrieve that you are non planing for outlined user but in bend everyone becomes your user. It is frequently really hard to make and plan a feasible solution that all people will hold user friendly, which is why designers and interior decorators seem to steam off from this rule. Catlin illustrates that non merely can plan be an aesthetically delighting cosmopolitan infinite but green rule can besides be an applied in a superb manner.Plants CitedAccess Living. Ed. Geekpak.

Interview With Special Education Teacher Essay

What she finds to be the most satisfying part of her job is when a parent is involved in their child’s education. This involvement and investment helps the student succeed. Unfortunately, there are many parents who don’t return calls or attend meetings, which really hinders the child’s ability to grow since they are not receiving the same support in the home as in the school. She also mentions how great of a staff she works with in her building. This ranges from speech therapy, hearing/ vision assistance, the counseling office, social workers, the career  center, reading services and numerous teachers. The staff has been meeting as a team for the entire ninth grade this school year because they have found that this class has many emotional needs. It is wonderful that there is a group of dedicated people who truly care for the students they work with. The most frustrating issue she and her team have faced this year is not only the common core curriculum and Annual Professional Performance Review (APPR) mandated by New York State, but also the lack of attendance of many of the students. The staff calls Child Protective. Services (CPS) or Persons In Need of Supervision (PINS) program and takes students to court, but there are no concrete threats. The students know that there is no real consequence for not attending school besides failing. Unfortunately, Niagara County does not take the parents to court as Erie County does. It is unfortunate not to be able to hold the parents accountable for their own child’s education and essentially their well-being. Her advice to those starting out in the education field is to be prepared to work hard for less pay than most other fields. However if it is your passion, love it and live it. The students are the pay, is what she said. There are students that truly appreciate the teacher and to see them enter ninth grade and grow to be successful twelfth graders makes her smile. She is still in contact with many of her students and some even ask her for help in college courses. Parents of past students remain in contact, also. It is nice to know that one person can make a difference in the lives of many students and families, alike. Her main advice would be enter the field and don’t get defeated by all the political issues. It will be hard work, but very rewarding work.

Alzheimer’s Disease Amyloid Precursor Protein Gene

Alzheimer’s disease, AD, is a distressing condition that involves the decline in cognition of the mind which results to psychotic disorder, and affective and behavioral disturbances (Bloom 9). It is a progressive central nervous system disorder and the main cause of dementia (Stavljenic-Rukavina 1). Alois Alzheimer in 1907 reported the case of a 51-year old Frankfurt woman who died in dementia (Bloom 9). He described the neuropathological condition of the woman with neurofibrillary tangles or NFTs and amyloid plaques or NPs (Bloom10). NPs are extracellular beta-amyloid peptide or A?Spherical deposits closely related to dendrites, reactive astrocytes, dystrophic axons, and activated microglia (Felician and Sandson 19). Thus, for several decades, collaborative efforts of experts from different scientific and medicinal endeavors were devoted for the neurological and pathophysiological characterization of this disease (Bloom 9). As such, the roles of four specified genes, as well as the mechanism of oxidative stress, tau, inflammation, hormonal changes, and inflammation on the AD’s neurodegeneration have been the central theme of scientific studies conducted on this disease (Felician and Sandson 19).As experts continuously gained insights on the mechanisms of neurodegeneration, pharmacological strategies are concurrently devised for the development of appropriate drug treatment and interventions (Felician and Sandson 19). Molecular Mechanism Early and late onset ADs are types of familial AD which are genetically heterogeneous. Familial AD is accounted for 10% of AD cases from 30-60 year old patients and ascribed to three types of genes which included APP, presenilin-1 or PSEN1 and presenilin-2 or PSEN2 (Stavljenic-Rukavina, 1).Nonetheless, the mutations in these genes also cause A? -level increase; A? is generated by proteolytic APP fragment that was also observed in the brains of AD patients (Stavljenic-Rukavina, 2). However, not all AD cases can be attributed to the three identified genes. Genes are then the most important determinant of AD development (Stavljenic-Rukavina, 2). On the other hand, there is a great chance for children with parents having history of familial AD to inherit the genetic traits and develop either early-onset or late-onset AD (Jayadev et.al. 375). As well, AD development threat in the offspring is directly related to age; the tendency of AD occurrence among children of parents with historical AD background increases as the children gain progress in their growth and development (Jayadev et. al. 375). The pathogenesis of Alzheimer’s disease, on cellular level, has been consistently observed. The pyramidal neurons are the type of cortical cells that are fundamentally deteriorated in AD pathogenesis resulting to the spread of NPs and NFTs in cortex areas (Felician and Sandson 20).Both NPs and NFTs are normally found in brain areas in the aging process but their concentrations and densities are pecu liar in the case of AD (Felician and Sandson 20). Originally, NPs are found at the amygdala and concentrated in parietal association and order temporal cortex parts (Felician and Sandson 20). In the maturity of AD, NPs can also be observed in hippocampus, in other structures of mesial temporolimbic brain, and even in cortical and meningeal blood vessels (Felician and Sandson 20).Luckily, the areas for sensorimotor and visual are remained unaffected. Meanwhile, in the early stage of AD, NFTs can be found hippocampus, amygdala, and in entorhinal cortex, the association cortex has abundance of NFTs (Felician and Sandson 20). However, NFTs are not exclusively for the cases of AD, these are also detected in the several cerebral troubles like in dementia pugilistica, postencephalitic parkinsonism, and subacute sclerosing panencephalitis (Felician and Sandson 20). The formation of NPs is attributed to the A ? peptide deposition; A ?peptide types that only differ in C-terminal are common in cerebrovascular and extracellular plaques (Felician and Sandson 19). A ? peptide, made up of 39-43 amino acids, is normally generated from APP or amyloid precursor protein. In addition, the series of hydrophobic C-terminal is crucial in its solubility and amyloid formation rate (Felician and Sandson 19). As such, A ? with 40 amino acids, A ? 40, as well as A? peptide with 42 and 43 amino acids or A? 42 and A ? 43 respectively (Felician and Sandson 19). However, in vitro, the variants of A?42 and A? 43 can easily form insoluble fibrils as compared with the A? 40 variant (Felician and Sandson 19). Furthermore, the incubation of these A? variants can immediately lead to coalescence implying the possible amyloid plaque deposition through these components. In line with this, diffuse plaques have nonfibrillary and A? soluble constituents denoting the senile plaques’ early stage (Felician and Sandson 19). Likewise, diffuse plaques have A? deposits in the absence of neuritic degener ation (Felician and Sandson 19).On the other hand, neurofibrillary tangles, comprised of abnormal bundles of intraneuronal filaments, are made up of tau microtubule-associated protein with high degree of phosphorylation (Felician and Sandson 19). The degree of phosphorylation is largely dependent on the enzymatic activities of kinases that are not yet fully understood (Felician and Sandson 19). Nevertheless, the intraneuronal abnormal filaments arrange themselves in either parallel or helical bundles in perikaryotic cytoplasm that make them in contact with the dentritic processes (Felician and Sandson 19).The amyloid precursor protein, a membrane glycoprotein, is consisted of 28 A? extracellular residues and 12 to 15 putative transmembrane residues (Felician and Sandson 20). It also occurs as 695, 751, and 770-amino acid isoform. While the 695-amino acid isoform occurs mainly in neurons, 770 and 751-amino acid forms are seen on both non-neural and neural cells along with protease in hibitor domains (Felician and Sandson 20). APPs are carried into the cell membrane by secretory vesicles and may undergo proteolytic bond breakage through the action of ?-secretase (Felician and Sandson 20). Consequently, this cleavage generates ? -APP, a soluble ectodomain and the precursor for A? peptide production through cleavage in A? domain. As the generation of soluble APP is, in vitro, ascribed with the activity of protein kinase C, uncleaved APP is inferred to take the proteolytic pathway (Felician and Sandson 20). On the other hand, APP intracerllular recycling and management are done through endocytotic or endosome-lysosome means. The endocytotic route causes proteolytic cleavages by means of ?– and ? -secratases leading to the synthesis of A? (Felician and Sandson 20). Moreover, A? production is enhanced by intracellular calcium concentration which denoted the significance of calcium-rich proteases in A? production (Felician and Sandson 20). In vivo, APP cleavage occurs at N-terminus at the A? -region through the action of ? -secretase and at the C-terminus by means of ? -secretase activity (Mohan 1). Also, APP can take a pathway facilitated by ? -secretase at the A? -peptide domain producing soluble ? -APP (Mohan 1).Ezymes can also possibly attack APP without A? -peptide generation (Stavljenic-Rukavina, 1). Since the putative ? -secretase, under the control of kinase C, regulates the generation of soluble APP, any agents that supports this metabolism may hinder the A? production (Felician and Sandson 21). As well, A? deposition may also be lessened by drugs which inhibit APP cleavage into ? – and ? -secratases (Felician and Sandson 21). Nonetheless, agents that can impede A? coalescence would decrease its neurotoxicity effects (Felician and Sandson 21).After the formation of amyloid plaques, neurofibrillary tangles and inflammation dictates the death of neurons (Stavljenic-Rukavina 1). In relation to this, microglia and astrocytes ce lls of the brain are heavily affected by inflammatory process (Stavljenic-Rukavina 1). In AD patients, astrocytes are enlarged and produce prostaglandin which in turn sends signal to activate the inflammation mediated by arachidonic acid (Stavljenic-Rukavina, 1). On the other hand, microglia generates free radicals which cause neurons’ death (Stavljenic-Rukavina 1).Meanwhile, cell nutrients as well as its regulation components are transported through the microtubules in which structural properties are mainly dependent on tau protein (Stavljenic-Rukavina 1). In AD condition, the tau lessens its capability to bind with microtubules and binds with other tau protein resulting to knots of helical filaments called as neurofibrillary tangles (Stavljenic-Rukavina 1). APP Duplication is Sufficient to Cause Early Onset Alzheimer’s Dementia with Cerebral Amyloid Angiopathy Studies showed that A? encoding through APP gene expression leads to the development of Alzheimer-type demen tia (Sleegers et.al. 2977). APP genetic expression results to elevated levels of A? 42, a 42-amino acid product of the proteolytic process (Sleegers et. al. 2977). Aside from the cleavage of APP into alpha, beta, and gamma secretases, high APP genetic expression results to elevated levels of A? 42 and A? deposition (Sleegers et. al. 2977). Meanwhile, it has been long known that APP level triplication in Down’s syndrome patients results to the development of Alzheimer type dementia at early stage; the APP excessive expression leads to neurodegeneration and A? deposition (Sleegers et. al.2977). In relation to this, it was reported that families with cerebral amyloid angiopathy and early onset Alzheimer type dementia had APP genomic duplications which implied that APP over-expression, without full trisomy 21, has triggered the Alzheimer-type dementia (Sleegers et. al. 2977). In addition, Alzheimer-type dementia patients have elevated APP mRNA levels in their brains (Sleegers et. al. 2977). Further, the variation on the transcription of APP gene due to genetic factors was believed as the underpinning factor in the pathogenesis of the disease (Sleegers et.al. 2978). In fact, three APP mutations were observed on Alzheimer-type early-onset dementia patients. These mutations, as seen in vitro by means of trisomy 21, caused a two-fold elevation of in APP transcriptions (Sleegers et. al. 2978). With the aforementioned evidences on APP elevation through APP genomic mutations or duplications which resulted to the development of early onset AD, it could logically infer that A? has a crucial role in its aetiology (Sleegers et.al. 2978). Hence, for the evaluation of APP locus duplication on Alzheimer-type dementia cases, Sleegers et. al. conducted a study on Dutch population with early onset Alzheimer-type dementia patients. Material and Methods In the approval of the University of Antwerp medical ethical committee, the respondents of this research were recruited form an epidemiological study on early onset AD in several provinces of The Netherlands and in Rotterdam (Sleegers et. al. 2978).Patients with early-onset dementia diagnosis were enlisted based on the recommendation of medical experts and healthcare providers. As such, the assessment of the patients’ conditions was done in accordance with the standards of the Stroke-Alzheimer’s Disease and Related Disorders Association, and the National Institute of Neurological and Communicative Disorders (Sleegers et. al. 2978). Medical records of the patients and their respective relative with similar trait inheritance were made available for an in-depth examination.Meanwhile, for the assessment of genetic inheritance, 111 patients with ages 33 to 65 years old of which had 75 respondents with familial background of either late or early-onset of dementia and 10 of which have autosomal dominant inheritance history for several generations of their respective clans were studied (Sleegers et . al. 2978). The genomic DNA or gDNA was derived from lymphocytes and alleles of APP were measured by means of real-time polymerase chain reaction, PCR (Sleegers et. al. 2978).Also, the PrimerExpress software was utilized for the design of ? 2-microglubulin or hB2M, exon 5, 11, and 18, ubiquitin C or hUBC, ATP5J, APP, and GABPA (Sleegers et. al. 2978). As the APP alleles were normalized for hB2M and hUBC, 20 nanograms of genomic DNA were combined with the PCR and 400 nanomoles of the respective primers (Sleegers et. al. 2978). Finally, the duplication of the samples was done by means of dosage quotients or DQs calculation through six normal individuals and dementia patients.Patients with trisonomy 21 were also included as controls (Sleegers et. al. 2978). Fluorescence in situ hybridization, FISH, was utilized to determine APP genomic duplication (Sleegers et. al. 2978). FISH was performed on both interphase nuclei and metaphase chromosomes while the Epstein-Barr virus-transformed pa tients’ lymphoblasts were taken from the metaphase period by means of 0. 1 microgram/milliliter colcemid treatment and incubated, at 37 °C for 25 minutes, in hypotonic solution of 1 molar sodium hydroxide, 30 millimolar glycerol, 0.8 millimolar magnesium chloride, 2 millimolar HEPES, and 1 millimolar calcium chloride (Sleegers et. al. 2978). This suspension then was used for 106 cells per milliliter as the chromosomes’ mechanical stretching was done through cyto-centrifugation. On the other hand, the Multiplex Amplicon Quantification, MAQ, was applied in the detection of APP locus duplication. MAQ was comprised of multiplex PCR amplification of the reference amplicons and targets which were tainted with fluorescent substance (Sleegers et. al. 2978).After MAQ, DNA fragment analysis, and comparison target amplicon DQ between control individuals and the patients were done (Sleegers et. al. 2979). Results and Discussion Real-time PCR APP measurements of 10 probands showe d heterozygous duplication (Sleegers et. al. 2982). Based on the Dutch population sample, APP duplication along with segregation pattern and neuropathology tantamount to autosomal dominant inheritance and AD with excessive CAA were identified with APP duplication in a family (Sleegers et. al. 2982).Specifically, the genomic APP locus duplication were observed in five of the 65 family cases with early onset AD autosomal dominance while APP duplication was detected in a single out of ten family cases early-onset AD autosomal dominance (Sleegers et. al. 2982). Even though these numbers are small, the data generated from this study illuminated the significance of genomic APP locus duplication assessment when simple mutations were excluded in AD known genes (Sleegers et. al. 2982). In the 65 patients with familial AD history, a single genomic duplication was identified (Sleegers et. al. 2982).In addition, the genomic duplications among the Dutch samples have 1. 8% overall frequency and 2 . 7% frequency in AD patients and family (Sleegers et. al. 2982). In contrast, duplication was failed to be detected on 36 patients with irregular early-onset AD which denoted that the duplication of de novo genomic APP is a weak cause of early-onset Alzheimer-type dementia (Sleegers et. al. 2982). Moreover, the duplication observed among the Dutch family samples has only APP which proved that genomic APP duplication, regardless of adjacent genes, has the capacity for AD and CAA mixed phenotype (Sleegers et.al. 2982). As well, duplication size differences signified the non-specific recombination substrate from the genomic attributes of APP locus; APP rather is in increased recombination region as imparted by other factors such as low transcription repeats (Sleegers et. al. 2982). Nevertheless, the mutation that affects APP expression among 4. 5% of the Dutch participants that either genomic APP duplication or APP mutation promoter carrier, are the frequent cause of Alzheimer-type de mentia (Sleegers et. al. 2982). Polymorphism in the Promoter of the Human APP GeneThe cleavage of APP produces A? with associated neurotoxicity; hence, genetic studies postulated that abnormal A? deposition neuropathologic AD conditions (Athan, Lee, Arriaga, Mayeux, and Tyco1793). The abnormal deposition of A? in AD patients has been ascribed to APP gene missence mutations and the proteolytic APP cleavage producing A? 42 which in turn triggers the development of early-onset AD (Athan, Lee, Arriaga, Mayeux, and Tyco1793). The most solid proof for this notion is the case on trisomy 21 wherein the duplication of APP gene results to increased A?peptide level and aggregation of such in the amyloid plaques of the brain (Athan, Lee, Arriaga, Mayeux, and Tyco1793). While the presenilin enyzymes enhance fibrillogenic APP conversion, the APOE or alipolipoprotein-E elevates A? coalescence and deposition (Athan, Lee, Arriaga, Mayeux, and Tyco1793). Since A? production is associated with APP con centration and on other factors in both A? and APP syntheses, it was hypothesized that the expression of APP gene is a determinant of AD development (Athan, Lee, Arriaga, Mayeux, and Tyco1793).Recently, a study reported the weak relation between AD inheritance and microsatellite sequence in the APP first intron and a tetranucleotide non-association with AD (Athan, Lee, Arriaga, Mayeux, and Tyco1794). Hence, to further scrutinize this issue, Athan et. al. anchored their study on APP promoter variant screening in tri-ethnic populations which included white, Caribbean Hispanic, and African-American as they intended to determine APP promoter identities. MethodologyThe respondents in this study were Manhattan residents of Washington Heights with ages of more than 65 years (Athan, Lee, Arriaga, Mayeux, and Tyco1794). Personal interview and medical background check, neuropsychological, physical and neurological examinations were done on the participants. In addition, individuals with quest ionable dementia, Parkinson disease, and other types of dementia were excluded in the study. Consequently, a total of 1,077 participants was successfully enlisted, whereas, 16% of them has family history of stroke (Athan, Lee, Arriaga, Mayeux, and Tyco1794).For genotyping, DNA from 1,013 respondents was taken as the panel of neuropsychologists and physicians established the criteria for the identification of AD patients along with the Clinical Dementia Rating Scale (Athan, Lee, Arriaga, Mayeux, and Tyco1794). The oligonucleotide primers used for APP promoter PCR amplification came from GenBank (Athan, Lee, Arriaga, Mayeux, and Tyco1794). From genomic DNAs and by means of Platinum Taq DNA Polymerase, the fragments were amplified while the product sequence was determined through dye terminators (Athan, Lee, Arriaga, Mayeux, and Tyco1794).Meanwhile, 15 microliter of the PCR products was introduced into WAVE fragment DNA analyzer (Athan, Lee, Arriaga, Mayeux, and Tyco1794). The haplotyp es PCR products were individually cloned through pGL3 vector in between SacI and Bg III sites (Athan, Lee, Arriaga, Mayeux, and Tyco1794). On the other hand, U-87 MG glioma cells were cultured with the solution of Earle’s balanced salt and 2 millimolar L-glutamine with 10% fecal calf serum in EMEM medium (Athan, Lee, Arriaga, Mayeux, and Tyco1794).At 70% confluence, the cells were transferred by means of FuGene 6 reagent and pGL3 vectors were added to transfected DNA to maintain a constant concentration of about 1 microgram per plate of 35 squared millimeter (Athan, Lee, Arriaga, Mayeux, and Tyco1794). While the isotonic solution of phosphate-buffered sodium chloride was used to wash the U-87 cells, the 250 microliter Reporter Lysis Buffer was applied for cell lysis (Athan, Lee, Arriaga, Mayeux, and Tyco1794).After this, the centrifugation of the cell extract was done at 10,000 g for five minutes. From the supernatant, 20-microliter aliquot was taken and combined with 100 mic roliter Luciferase Assay Buffer for luciferase activity measurement (Athan, Lee, Arriaga, Mayeux, and Tyco1794). Then, with 10-20 microliters of the lysate ? -galactosidase assays were performed. This ? -galactosidase measurement was utilized for the normalization of the luciferase data (Athan, Lee, Arriaga, Mayeux, and Tyco1794).Each allele was counted and by sample proportion calculation, the frequencies were computed (Athan, Lee, Arriaga, Mayeux, and Tyco1794). For the ethic group comparison of allele frequency, chi square analysis was applied while logistic regression was utilized for APP promoter and AD polymorphisms odd-ratio calculation (Athan, Lee, Arriaga, Mayeux, and Tyco1794). As well, for each ethnic group, logistic regression was employed as the data were classified with respect to the APOE allele’s occurrence or non-occurrence as education and age discrepancies were adjusted.Finally, Hardy-Weinberg equilibrium was analyzed through chi square analysis while the e thnic comparison of APP promoter and AD polymorphisms odd-ratio calculation as their education, age, and sex were adjusted (Athan, Lee, Arriaga, Mayeux, and Tyco1794). Results and Discussion Two types of APP promoter polymorphisms were detected and identified, with respect to the starting site of the transcription, as G>C at +37 and G>C at -9 variants (Athan, Lee, Arriaga, Mayeux, and Tyco1797).In connection to this, +37C allele was typically observed among 18% African-American respondents while European and Caribbean-Hispanic have 3% and 10% respectively (Athan, Lee, Arriaga, Mayeux, and Tyco1797). Although +37C allele was commonly observed among AD patients, the adjustment of their socio-demographic attributes with respect to this allele produced non-significant observations (Athan, Lee, Arriaga, Mayeux, and Tyco1797). Also, -9C allele was hardly detected for disease association.On the other hand, even though the adjustment with respect to socio-demographic traits was made, still a strong link was found between APOE allele and AD (Athan, Lee, Arriaga, Mayeux, and Tyco1797). Moreover, the evaluation of both +37C and -9C allele variants in U-87 glioma cells through promoter-reporter assays has resulted to non-significant promoter activity (Athan, Lee, Arriaga, Mayeux, and Tyco1797). The early onset, less than 60 years old, of AD has been ascribed to APP, PSEN1 and PSEN2 while the late stage, greater than 65 years old, AD development has not yet fully explained by the genetic model (Waring and Rosenberg 329).The development of AD in late age stage was associated with APOE and to other reported genetic variants and alleles, however, they still insufficient to plausibly explain the mechanism involved in the AD occurrence (Waring and Rosenberg 329). Summary Alzheimer ’s disease is a progressive degeneration of the capacity of the mind for cognition thus affecting the psychological and affective attributes of the inflicted individual.Based on genome-wide stu dy, children of parents with familial Alzheimer’s disease are more prone to inherit and develop this condition either as they take progress in their growth and development or at the senescence stage of their lives (Jayadev et. al. 375). The primary pointed culprit for this cognitive deterioration is the beta-amyloid peptide which is a part of amyloid precursor protein. APP passes through the fatty membrane of the cells and delineated in the different areas of the brain, even though, the normal function has not yet been fully known.As APP is attacked by enzymes, fragments are generated including A? -peptide with associated neurotoxicity. Sleegers et. al. in 2006 found the coincidence of cerebral amyloid angiopathy with Alzheimer’s disease in a Dutch multigenerational family. This genomic duplication was attributed solely to APP gene expression that was also observed in 65 Dutch families with early-onset of AD cases. However, APP locus duplication was not observed in 36 AD patients that signified the case of de novo mutation. On the other hand, Athan et. al.in 2002 reported the two types of APP promoter polymorphism which involved +37C and –9C alleles. Moreover, they found a strong link between AD inheritance and the apolipoprotein-E role. In this connection, the genetic traits of every individual should be scientifically scrutinized for an accurate determination and identification of the substance involved in the development of the disease in parallel with its molecular mechanisms.

University of Colorado Research Paper Example | Topics and Well Written Essays - 3000 words

University of Colorado - Research Paper Example The notion of the university is the targeted elevation of academic standards and reaching the heights of one of the comprehensive public universities of the modern world and also striving for serving the people of Colorado with their engagement with the world of excellence delivered through its teaching, research creative work and continual flow of services (About CU-Boulder, n.d.). The university with its prime agenda on the development of the academic scenario has implemented several strategy implications among which the voucher system is one of the noteworthy issues. In 2004, the university passed a legislation which introduced the nation’s first voucher-based approach for the purpose of financing the higher education. It was introduced in the name of College Opportunity Fund (COF). The strategy formulation of the policy and the implications of the same came through the hands of the educational leaders which altered the traditional approach of subsidizing the public higher education scenario through the direct expropriation with a combination of vouchers and â€Å"procurement contracts† for educational services. ... rishing academically and also a drive to make the educational institutions become more entrepreneurial in nature and throttle those institutions into a market driven paradigm (Prescott, 2010). The purpose of the paper is to analyze the role of several players or agents in the effective management of the voucher system which includes the macroeconomic factors like political system, structural system, human resource management and on the microeconomic factors including the Planning, organization, staffing policies, focus and the control mechanism in order to develop an insight which will provide us with the conclusion that to what extent this system has been successful in the enriching the educational set up and the enrolment of the students from the lower stratum of the society. Critical analysis will be exercised discussing the strength, weaknesses, opportunities and threats encountered by the organization through the introduction of the system. Finally recommendations will be discus sed with new improved strategies for attaining more development in the academic platform and also of restructuring strategies if necessary. The paper will highlight on the development process of the Colorado College Opportunity Fund (COF) to evaluating its performance and suggesting recommendations for the future optimistic performance of the plan. II. Investigative Analysis The system of educational voucher system is generally an education finance system where the students are provided with tuition certificates that can be used for attaining the private or the public schools. There are varied forms of vouchers that can be paid by the government or other private corporation funds. Each of the funds can be used for addressing the needs of varied students and understanding their distinct

Happiness and the Limits of Satisfaction Research Paper

Happiness and the Limits of Satisfaction - Research Paper Example I think increased choice does not make us happy, and therefore, individual choices should not be paternalistically restricted because happiness is not the highest aim of human conduct. There are those actions which add to pleasurable activities that cannot be taken as always right. Moral virtue does not imply end of life since life can continue with unhappiness, misery, and inactivity. Therefore, moral virtues are gained by behaving virtuously but they can be damaged by either defect or excess. People are free to determine what type of self they will have, what type of people they will be. For instance, people are free to be frivolous or serious, selfish or selfless (Ignacio 67). The most significant thing is that at least one should be in a position to maintain the goal of maximal self-determination as a desirable moral and psychological state. Hence, a fully self-determined person is one that is unconstrained by biology, social constructions or by habit. Such a person will operate without constraints, which in turn enables him or her to make choices in the world to maximize his or her preferences in maintaining tenets of rational choice (Mike 42). Happiness is the central core of living, which depends entirely on cultivation of virtues. Playing the mean is the way of cultivating virtues that includes moral virtues for the attainment of individual happiness. Playing the mean is the virtue between two extreme excesses and deficiency. For instance, exercising the act of justice in getting too little or getting too much. Therefore, human beings make choices depending on the circumstances that surround them by choosing on one option and neglecting the other. The task of ethics or tenets of rational choice were to come up with the highest and the best good that is found in human life. Thus, all human activities always aim at some recognized higher end that we always consider as good. Most activities that human beings incur in life are a

Soundscapes in which Music operates in a Worship Setting Essay

Soundscapes in which Music operates in a Worship Setting - Essay Example The "Tao Meditation", is used to convey the worshiper into a deeper and more peaceful state of worship and spiritual growth. The music is focused in soft Tibetan sounds, with wind chimes, gongs, bells and gentle natural sounds to convey a deeper sense of inner peace and a desire to enter into the inner reaches of ones spirituality. The covey of the simple music allows for the worshiper to find a peaceful oasis of relaxation and stress relief from the business of life, to tap into the inner energies of spiritual awareness and silence. The setting, that I experienced was a simple room, lots of natural light where the worshipers like myself sit in simple seating set in a semi circle, with a screen at the opening of the circle that provided the features that impact upon the sight sensory experience. The leadership by a competence alternative worship leader gently brought one into a sensory but spiritual experience. The significance of the experience is the fulfillment of the inner spirit ual finding release in the gentle art of meditation. There was no specifically set ritual, just a simple group desire to come together to enjoy and experience a deeper and more meaningful spirituality. The ritual if any; or indeed order, was the gentle leading of the group by the leader into the peaceful state of meditation. ... The leadership by a competence alternative worship leader gently brought one into a sensory but spiritual experience. The significance of the experience is the fulfillment of the inner spiritual finding release in the gentle art of meditation. There was no specifically set ritual, just a simple group desire to come together to enjoy and experience a deeper and more meaningful spirituality. The ritual if any; or indeed order, was the gentle leading of the group by the leader into the peaceful state of meditation. Gently listening to the noises and sounds of the music and visualizing the scenes being shown on the screen, before us, invoked this. The meditation allowed each of group of worshipers to concentrate on their own personal spiritual journey and belief structure. The simplicity of the meditation enacted a sense of restfulness, peace and an inner desire to enjoin with the God force or life force within each of us. This was drawn out by viewing the many simple and colorful shapes that were sometimes floated, phased in and out on the screen before us then melting into the distance of the landscape on the screen. The group were able to discuss the experience after its conclusion in a facilitated discussion led by the worship leader. Many of the participants were able to explain that it allowed them to tune into the higher self or as some put it, the "God force" within us. What I enjoyed about the experience was that it allowed one to maintain ones own identity and individuality, without placing formal belief structures and dogmatic systems before the simplicity of simply and gently worshiping and enjoying peace with God. The second experience was completely different in its setting and style. The setting was a Methodist Church, which
