Film and Countless Alien Eggs Essay

I was in the middle school. I still remembered the feeling when I first watched this film. It was so scary that I couldn’t even breathe, and I once dreaded that these aliens would come to our planet and destroy our humanity. There is no doubt that this film is a masterpiece in the Sci-Fi/horror film history. The director Ridley Scott made an amazing film. The story mainly tells about a commercial towing spaceship, which carries seven crew members, and receives a beacon form a planet, so they decide to check it out. Three of crew member Dallas, Kane and Lambert discover a derelict spaceship which contains countless alien eggs; one of these attacks Kane and makes him unconscious. After Kane is brought to the ship, the strange thing happens. An alien bursts from Kane’s’ chest and kills all the crew members except Ridley. By her intelligence and braveness, she finally kills the alien and escape from the spaceship. Films about UFO and spaceships are extremely popular in the film industry especially in America, but in other countries it’s not popular at all. I think it is because schools in United States focus more on educating students’ imagination and creativity. People love to see films about future world and extraterrestrial life. As we know, our universe is extremely large; a lot of people believe that aliens do exist somewhere. Some rumor says they visited us and government knew it, but for some reason they didn’t want people to know. The more government wants to conceal the existence of alien, the more people want to know the truth. That’s why Sci-Fi movies can succeed in the box office so well. The Alien is one of the most successful Sci-Fi movies in the history. Some people think it also can be categorized as a horror movie too. There are so many scary moments in this film; some are really gross and disgusting. The effect of chest bursting of Kane is still amazing; even it was a movie that filmed 30 years ago. Director created a very scary creature, the alien. They have no gender, or you can say they are hermaphrodite. They have no womb and reproduce really fast, and their blood is made by strong acid, which can penetrate several floors of the giant spaceship. It makes them hard to kill, and the scariest thing is they use human body to reproduce. Once the baby alien ready to go from its host, they will burst out from their father/mother’s chest and instantly kill him/her. The alien grabs all the audience’s attention. Its giant body and gross drooling mouth creates the scary atmosphere, which make audience dread and anxiety. The success of Alien was quite closely linked to the background of America at that time. The Alien was born in the era of the Cold War. People were living under the tremendous pressure from the other countries. The feeling of the panic to the uncertainty just like an alien was hiding in the darkness, which was going to kill someone. By watching this film, audiences can release the pressure and forget the pain of real life. The Alien is an amazing film, which blends elements of Sci-Fi and horror to create a very horror and fantastic film. I would love to watch this movie again and recommend to all the people who like Sci-Fi and horror movies.

The role of ApoE and its isoforms in Alzheimer’s disease The WritePass Journal

The role of ApoE and its isoforms in Alzheimer’s disease The role of ApoE and its isoforms in Alzheimer’s disease IntroductionThe ApoE gene (Physiological Functions)The ApoE isomersApoE AÃŽ ² Aggregation (Fibrillogenesis)AÃŽ ² Clearance by ApoE ApoE and Neuronal InflammationConclusionBibliographyRelated Introduction Research into the genetic causes of Alzheimer’s disease have progressed considerably and currently at least three different genes are known to be linked with AD pathogenesis. Of these the apolipoprotein gene E (APOE), an amino acid glycoprotein, is one of the main focus of research over the last decade or so and significant associations between one particular isoform of the gene and the onset of AD have been reported. This isomer, referred to as the ApoE 4 allele, has been implicated in AD pathogenesis while other forms of the gene the ApoE 2 and the ApoE 3 have been reported to have a protective effect against the onset of AD. Though research has confirmed this variable effect of the different forms of the ApoE gene, there is still a lack of concrete evidence as to the exact pathway and the mechanism by which ApoE 4 contributes to neurodegeneration in AD patients.   A brief review of related research would provide us more insight into the various pathological actions of Apo E 4 and how these multiple factors could lead to a gradual cognitive decline which is symptomatic in Alzheimer’s patients. The ApoE gene (Physiological Functions) ApoE is an amino acid glycoprotein that is found mainly in the liver and the brain. In the brain, ApoE is predominantly secreted by the astrocytes. Two other forms of apolipoproteins namely ApoA-1 and ApoJ are also found in the brain. In vitro studies of these two genes have so far suggested that both of them exhibit a neuroprotective effect. Both these proteins bind to AÃŽ ² and therefore are thought to reduce AÃŽ ² aggregation in the brain which is a known marker of AD.   However, in vivo studies have not replicated such results and so the protective roles of ApoA-1 and ApoJ are not yet clear.   The ApoE supports cholesterol equilibrium by serving as a ligand during endocytosis of lipoprotein particles by LDL receptors. Research is divided in the opinion that the cholesterol released from ApoE mediated endocytosis process is actually used for improving the synaptic connections or the synaptic plasticity. Mice based in vivo studies have not attested to this synaptogenesis. (Kim et.al, 2009) The ApoE isomers Three single nucleotide polymorphisms of the ApoE gene are commonly identified in humans. These are the apoE2 (cys112, cys158), apoE3 (cys112, arg158), and apoE4 (arg112, arg158) respectively. (Kim et.al, 2009) The structural and functional aspects of the three isomers of ApoE are totally altered though they differ by only one or two amino acid positions.   Studies have reported strong immune-reactivity of the human apoE4 gene on amyloid plagues and the apoE4 isomer has been associated with having a strongest risk factor for AD. Some studies such as (Bertram et al., 2007) and (Bertram et al., 2009) have attested to this role of the apoE4 isomer in AD.   Bertram et al., 2009 for instance reported that people with a single copy of the apoE4 gene had a three fold increase in risk for AD, while the   risk was 12 fold among those with a dual copy of the ApoE4 gene.   The results from studies also suggest the possible role of some environmental factors as research based on some eth nic groups have revealed that the ApoE 4 gene does not have a significant effect on AD. ApoE AÃŽ ² Aggregation (Fibrillogenesis) Several research studies have focused upon the potential role of ApoE 4 in causing AÃŽ ² aggregation and neuronal degeneration. This direct interaction between the ApoE 4 with beta amyloid is attributed in the pathogenesis of the disease. Therefore it was hypothesized that increased levels of ApoE 4 in the brain corresponded to increased formation and thickness of amyloid plaques. The findings from one comprehensive study by Tiraboschi et.al (2004) validated this hypothesis. The researchers in this study confirmed increased plaque density corresponding to increased levels of ApoE 4. This positive association was again confirmed by a more recent study by Reiman et.al (2009). The researchers of this study used an amyloid detecting agent such as Pittsburgh compound B (PIB) along with positron emission tomography to detect the levels of fibrillar AÃŽ ² in the subjects. The researchers then correlated this information among individuals with varied genetic risks. The results from the study clearly revealed that ApoE 4 homozygotes had the highest risk (91%) for developing AD while ApoE 4 heterozygotes had a moderate risk of 47% and finally ApoE 4 non carriers had only 20% risk of having AD. Furthermore, the mean age of onset of AD was also vastly different with ApoE 4 homozygotes at 64, heterozygotes at 76 and 84 years of age among non carriers.   This longitudinal study clearly provides positive evidence connecting the ApoE 4 gene with a high risk for AD.   Thus there is enough evidence that ApoE 4 gene may aid in ï ¬ brillogenesis and consequent cognitive decli ne. (Reiman et.al 2009). AÃŽ ² Clearance by ApoE Some studies have shown that ApoE by binding with soluble AÃŽ ² promotes the cellular uptake and ingestion of the ApoE –AÃŽ ² complex   Ã‚  by endocytosis.   However, isomer specific results for this ApoE facilitated cellular uptake of AÃŽ ² are still awaited.   Research has also focused on the possible clearance of   AÃŽ ² from the brain via the blood brain barrier. However, there is growing evidence that ApoE 4 might actually hinder or reduce this clearance of AÃŽ ².   Deane et.al (2008), a study based on mice reported that the clearance rate of ApoE 4 –AÃŽ ² complex is much lower than that for the ApoE2 and ApoE 3 complexes. Other recent studies such as Bell et.al (2007) and Ito et.al (2007) that focused on studying the AÃŽ ² clearance in humans found that the clearance rate along the Blood Brain Barrier (BBB) was significantly lower for the ApoE 4 –AÃŽ ² complex compared to that of simple AÃŽ ² peptides.   These studies offer enough evidence that ApoE 4 might actually increase the fibrillogenesis by directly affecting the AÃŽ ² metabolism in the brain. By reducing the clearance rate and promoting aggregation ApoE 4 gene definitely poses an increased risk factor for AD. ApoE and Neuronal Inflammation Several studies have reported that ApoE has marked anti inflammatory properties which explain the surge in their production in the aftermath of an injury. These studies hypothesize that ApoE is needed for maintaining the cholesterol homeostasis, and in particular for increasing the availability of cholesterol for neuronal repair and improving the synaptic plasticity subsequent to brain injury. (Slezak Pfriege, 2003 ). However studies have also reported differences in neurite growth and synaptic plasticity post neuronal insult in animal studies based on the genotype.   One transgenic mice study found that neuronal growth and synaptogenesis were markedly lower among ApoE 4 transgenic mice compared to ApoE3 transgenic mice. (White et.al, 2001) An extensive review of the neuroprotective effects of the various ApoE isomers by (Cambon et al, 2000) clearly showed differential effects between the isomers. Most of the studies reported that ApoE3 promoted synaptic plasticity and neurite gro wth. However similar positive results were not witnessed in the case of ApoE 4 alleles with some studies even reporting the negative effects of ApoE 4 on synaptic plasticity and neuronal growth.   Colton et.al (2004) found that the anti-inflammatory effects vary drastically between the ApoE isomers.   The researchers studied this variability in anti-inflammatory response triggered by the ApoE 3 and ApoE4 isomers by using in vivo experiment conducted on ApoE knockin mice. By studying Lipopolysaccharide (LPS) mediated inflammatory responses the researchers observed the differences between the isomers. The inflammatory response was much greater in the ApoE 4 knockin mice when compared to the ApoE3 Knockin mice. These studies suggest that the anti inflammatory response maybe less active in ApoE 4 and this might lead to neuronal damage as witnessed in AD patients.  Ã‚   (Kim et.al, 2009) Conclusion The review of studies has revealed that the ApoE isomers have differential effects on the AÃŽ ² metabolism in the brain. While the ApoE 2 and ApoE 3 isomers have been reported for their protective effects the ApoE 4 allele clearly seems to contribute to the AD pathogenesis. Results from recent fibrillar PET imaging studies suggest a clear positive correlation between the ApoE 4 allele and the density of amyloid plaque formation. It is clear that by slowing down clearance of AÃŽ ² as well as contributing to its aggregation in the brain, the ApoE 4 allele increases the susceptibility of a person for AD. It is also possible that the ApoE 4 also lowers the protective function by increasing the neuronal inflammatory response and by hindering neurite growth. More studies are necessary to understand the complex relationship between ApoE and AÃŽ ² and the levels of different isomers of ApoE and their corresponding impact on Neuroinflammation and neurotoxicity, etc. Bibliography Jungsu Kim, Jacob M.

J. Neurochem. 103, 2482–2490 Part 2 Fibrillar amyloid-ÃŽ ² burden in cognitively normal people at 3 levels of genetic risk for Alzheimers disease   (Reiman et.al 2009) This research study by Reiman et.al (2009) hypothesized that fibrillar amyloid accumulation is an early development in the onset of Alzheimer’s disease.   The researchers further hypothesized that the fibrillar amyloid accumulation precedes any recognizable symptoms of cognitive decline. Amyloid plaques are a distinct feature of AD as observed from post mortem studies. Given the hypothesis that fibrillar AÃŽ ² accumulation is observed even in healthy, non symptomatic adults, the researchers intended to study the effect of fibrillar AÃŽ ² burden as a predictor of future onset of AD on adults with normal cognitive function using Ante mortem  brain imaging studies. For this study, the researchers used Pittsburgh Compound B (PiB), a radio ligand that binds only with the fibrillar AÃŽ ² species. Earlier studies have also used this PIB for imaging studies of live human brain to observe the formation of fibrillar AÃŽ ² in healthy adults. This study by the authors is aimed to extend the previous studies by providing a genetic risk analysis and to understand the predisposition to AD based on an individuals APOE genotype. The APOE genotypes were identified by using blood sample analysis. The researchers used fluorodeoxyglucose PET, volumetric MRI and neuropsychological tests. Fibrillar imaging was done using 3 dimensional HR+ scanner.   The subjects of this study were all cognitively normal and late middle aged people representing a mixture of APOE genotypes. This was a longitudinal study and the subjects were assessed every 2 years. The researchers observed that cerebral glucose metabolism levels of those subjects carrying dual copy of the ApoE 4 (homozygotes) was significantly lower than that of the heterozygotes and the non carriers. With the PiB Pet images the researchers compared and correlated the fibrillar burden with the genetic risk to understand the predisposition for AD between the various isomers. The average Pittsburgh(PiB) distribution volume rations(DVR), which is a measure of the fibrillar AÃŽ ² accumulation, was on increase in all the three different groups in the 2 years period. One of the homozygote subjects developed mild amnesia and her DVR was close to that of an AD patient. Overall of all the 28 subjects (8 homozygotes, 8 heterozygotes and 12 non carriers), the ROI measurements pertaining to the different brain regions such as temporal, parietal, posterior cingulate-precuneus, basal ganglia, etc, was the highest among the homozygotes. The researchers used statistical analysis and found that the homozygotes had considerably higher ROI values when compared to the non carriers (P   .05) while the difference between the heterozygotes and the non carriers was not significant (.05   P   .11). When correlated the APOE4 and Fibrillar AÃŽ ² burden was found to be significant among both homozygotes and heterozygotes compared with the non carriers. The study authors successfully found that even in cognitively normal individuals there is a positive correlation between ApoE 4 and fibrillar AÃŽ ². The results from the study suggest that the ApoE 4 is clearly associated with increased AÃŽ ² aggregation and decreased AÃŽ ² clearance. The following PET map clearly indicates the various regions of the brain that are affected by AÃŽ ² accumulation. Group A represents the homozygotes while group B and C represent the heterozygotes and non carriers respectively. Longitudinal studies are very effective in following the growth of fibrillar AÃŽ ² accumulation as they provide a clear pattern of disease progression even in the asymptomatic stage. People who are in late middle age who are at risk for AD would greatly benefit from a prophylactic intervention based on the brain mapping study and their ApoE genotype. This study clearly contributes to our understanding that the ApoE 4 is directly involved in the AÃŽ ² interaction and the formation of Amyloid Plaques. By considering live brain images for the study the authors were able to clearly confirm the association between the ApoE 4 and AÃŽ ² fibrillar density and predict the increased susceptibility of people with that genotype. This study has large implications for the treatment of AD. By proving that AÃŽ ² fibrillar formation precedes a perceivable cognitive decline, this study recommends early interventions particularly for people with ApoE 4 genotype, as the current AÃŽ ² modifying treatments would be more effective before extensive AÃŽ ² accumulation has occurred. The researchers advocate the use of brain imaging studies combined with genotype based risk assessment as a potentially powerful tool in preventive therapy for people who are at a genetically high risk for AD. One of the drawbacks of the study is the very small study sample. A large cohort based longitudinal study would have provided more conclusive confirmation of the study results. Bibliography Eric M.

Free Essays on Public Education Vs. Private Education

Public Education v/s Private Education A person’s education is one of the most important factors in determining whether or not they will become a productive member of society. That is why when considering an education the quality of the education is almost as important as the education itself. So when private schools came into the picture the debate then began between public and private schools. Facing the technological revolution that we are going through without a good quality education a person will be left behind. Even though public and private schools are separate institutions they have to follow certain guidelines so there are a lot of similarities between the two. Such as, both school systems have the intentions of giving their students the best education within their means. Both have educated professionals that have decided to devote the rest of their careers to furthering the education of our youth. They each have set up rules hoping to keep it a positive learning env ironment. They both use standardized testing as a tool to evaluate the progress of their students. They can also access the weaknesses from these tests to improve the curriculum that they have composed. They also have clubs like volunteer groups that help out people in their surrounding community. There are also student governments where students elect students to improve upon the learning environment in which they are. Schools also have extra curricular activities like sports where students compete against other schools where they learn school spirit and how to work as a team. With all of these activities students can hopefully find something that they enjoy spending their free time. This also hopefully keeps children out of trouble. Private schools have a lot to offer.

6 Boundaries You Need to Protect at Work

6 Boundaries You Need to Protect at Work The pressure seems to be up these days, in almost every field. The workdays are longer, the weekends start to disappear. You might tell yourself you leave it at your desk, but then find yourself checking work emails on your phone at midnight before you fall asleep. Or worse, plugging in during vacation, when you’re supposed to be a million miles away from your job. But this kind of prolonged stress can actually be bad for both your health and your job performance. It is important to establish boundaries between the personal and the professional, to keep both parts of our lives healthy and productive.There are some things you simply do not owe to your employer. Here are 6 of them:1. Your HealthYour health is yours and only yours and only you can keep it up. It’s on you if the stress buildup happens so gradually that you don’t notice the effects of lack of sleep and hunching in your chair and not exercising or eating right. Before you turn into the office zombie, m ake sure to set up a routine that works for you. And make sure it includes work/life balance, mental space, rest time, and exercise. Once you make your plan, don’t let that one extra email from your boss derail it. Stick to your guns.2. Your FamilyWe all want to work harder to be able to support our families- make that little extra bit of money and push that little bit  further. But it can be easy to lose sight of how much you have to sacrifice to bring that extra home. Make sure you’re not sacrificing time. At the end of your life, you won’t regret not having that $8k raise. But you might regret not being home for dinner with your kids.3. Your SanityNo one can monitor this but you. And no boss should chip into your supply. Figure out what keeps you sane and balanced (hint: it’s probably your life outside of work) and make sure to claim both time and space for that. Know when it’s more productive to say no to a request, knowing you’ll work much better and harder if you’re relaxed and recharged and can tackle things afresh.4. Your IdentityWho you are is immensely important. What you do is only part of it- a big part, admittedly, but not everything. Keep in mind the things that are most important to you. Stay true to your values and maintain your integrity. This helps you keep your eye on the bigger picture in times of major stress at work.5. Your Professional ContactsYou owe your employer a lot. But your contacts from over the course of your career are yours. You can- and often should- share them with your company, but they are yours first and foremost and you must work to maintain them.6. Your IntegrityKeep your actions and beliefs in alignment, or you will feel horribly stressed and uncomfortable with the results. This is part of keeping the other five in check. Stay true to who you are and what you need and what you believe in. Act according to the best of yourself. If a boss asks you to compromise this, it might be time to find another boss.Remember: never underestimate the power of setting good boundaries.

Nuclear Power Research Paper Example | Topics and Well Written Essays - 500 words - 1

Nuclear Power - Research Paper Example Energy experts build huge dams in order to seize the water, which generates hydropower energy. Consequently, these constructions disrupt flow of rivers, which further result to plausible natural calamities for example, overflows in rivers. In addition, the construction of dams facilitates the impediment of natural flow of sediments in the river. Variably, the impediment results to rivers losing their banks. Moreover, individuals lose their existence because of the evictions, which follow the construction of the dams (Murray 2009). Development of nuclear power facilitates the following consequences: first, from the Fukushima Nuclear Disaster an individual depicts that the power supply in a nuclear plant suffers susceptibility of disability. For example, the machinery at Fukushima experienced a major nuclear accident because of the consequent chilling of the elements of retort. In addition, there are usually, constant releases of radioactive materials, which poison such paramount phenomenon as rivers (Bodansky 2004). Variably, contaminated waters from the plants leak out and cause melanoma and other precarious ailments to individuals. However, the Fukushima Nuclear Plant presents such advantages as generation of a significant high amount of energy from that single plant. Consequently, the plant does not release green house gases, which result to negative aftermaths of worldwide warming. Clearly, unconventional sources of power produce harmful green houses gases hence causing mountains to lose their snowing abilities (Bodansky 2004). Second, the Chernobyl Nuclear Meltdown released twenty five percent of radioactive reactor materials. Additionally, the historical accident registers deaths of individuals and continuous re-settlement of people who lived around that area. Further, there were various psychological impacts on the people who experienced the Chernobyl accident (Bodansky 2004). Although

Banking and international banking system Essay Example | Topics and Well Written Essays - 2000 words

Banking and international banking system - Essay Example Major financial institutions collapsed or near collapsed and credit markets were frozen. Bear Stearns and Sachsen LB (German bank), banks fell in 2007. It was followed by IndyMac Bank in receivership and demise of Lehman Brother in the quarter of 2008 (Drea 2009). After September 2008, panic in the financial global sector escalated and spread to other sectors of the economies. Investors were shocked by losses that they incurred on assets they thought were safe. There was strong evidence that contagion was linked with global financial crisis. This happened through liquidity and risk-premium channels in the financial markets. There was clear evidence informed by research that contagion during subprime crisis was clearly shown by significance of t-statistic for lagged ABX index returns in 2006 (Longstaff, 2010). Cross-market linkages were stronger and significant during subprime crisis indicating that that 2007 subprime crisis resulted in large shifts in trading activity, liquidity and funding in the financial markets across the world. A number of reasons have been advanced concerning the recent global financial crisis. ... The foreign money was savings piling up and owners wanted to invest their monies away from home where they were assured of some returns. The net inflow of foreign savings into the United States in 2006 was about 6 percent of the United States’ output. Instead of investing foreign moneys appropriately, financial institutions in the United States that received the surplus funds from Asia converted the monies to loans that were aggressively given to borrowers, especially homeowners. Mortgage market was attractive to investors because over 80 percent of mortgage market in the United States was securitized and they that their monies would be invest well (Financial Crisis Inquiry Commission, 2010). Securitization created the much needed diversification to investors and liquidity for business entities and individuals. Securitization refers to pooling mortgages together as securities. Once pooled as securities, they are sold to investors. However, investors and players in the industry lacked the business acumen to realize that securitization lacked clarity and transparency. Financial institutions also underestimated the risk associated with securitization and sold mortgage backed securities to investors across the world. The investors, which included banks, money markets, pension hedge and mutual funds, purchased the mortgage backed securities thinking they were safe. However, securitization was not able to provide protection against systematic risks. Even, credit rating agencies failed to take into account systematic risks and awarded the mortgage backed securities with AAA rating because it was considered low risk securities. Therefore, credit rating agencies could not price systematic risks into subprime mortgage pools. In

Criminology Theory Essay Example | Topics and Well Written Essays - 1000 words - 1

Criminology Theory - Essay Example In this movie, the views and characters of Derek are shaped by his neo-nazism beliefs. Derek is recruited into this group by Cameron Alexander, the neo-nazi leader. Alexander appoints him as the leader of the Caucasian kids. His role was to lead them against the Hispanic and the Black kids. Their attitude against them was shaped by the belief that these kids they lost their freedom and destiny to these people of different race. The Hispanics and the blacks were foreigners whose main aim was to exploit the resources of United States of America. On this basis therefore, Derek joined the group of the skinheads because of inequality in resource allocations, and he adapted their violent methods of agitating for their rights. The movie shows this by when he led a group of skinheads to destroy a Korean canteen. However, while in prison, Derek changes his ways of view. This is because he came to learn that there was a need of collaborating with each other, irrespective of race to survive. This is because of the inter-racial commerce that was pre-dominant in the prisons. The violent behaviors that Derek had were as a result of his failure of self-control, because he had already subdued the thieves, and he was not facing any threat. For instance, ordering the thief to open his mouth and busting his head with a bullet was a very cruel method of killing an individual. He could also control the manner in which he made his speech that had an effect of causing a violent mass action by the skin heads. The tone of his voice was harsh, and his words were full of incite. On this note, had Derek used some soft words, the riot that came as a result of the speech could not occur. It was possible for Derek to refuse the offer by Alexander, because he was not forced into joining the group. On this basis therefore, the behavior of Derek came as a result of his inability to control
