Summary News magazine, new neuroscience research have recently come about about the effects of Alzheimers disease, specifically sleep. Patients with Alzheimers have difficulty sleeping as well as build up of amyloid-beta protein. Although the research on the effects of sleep deprivation is new, Dr. Don’t waste time! Our writers will create an original "Aging in the News: The Brain May Clean Out Alzheimers Plaques During Sleep" essay for you Create order Barbara Bendlin (neuroscientist) found that those who had poor sleep (lower than the recommended 7-8 hours of sleep) had an increase in amyloid-beta protein in the brain. The research hypothesized that sleep deprivation could be an indicator or risk factor for cognitive problems, including Alzheimers (Beil). Other neuroscientists study the effects of sleep deprivation, such as Dr. David Holtzman who studies amyloid build up that could lead to Alzheimers disease in mice brains. The difficulty of Alzheimer research is that changes in the brain in humans develop slowly in a lifetime (decades) and the ethical implications of depriving sleep for long periods of time in sleep studies. Key Finding (Figure 1B) In Figure 1B, a sleep study was done at the Clinical Center at the NIH (Shokri-Kojori, 4483). Participants were asked to have a well rested night as the baseline and a sleep deprived night. Scientists then recorded the amount of 18F-florbetaben levels that bind to insoluble A42 plaques Shokri-Kojori, 4483). The red lines in Figure 1B represent 18F-florbetaben levels in females from a night of restful sleep to one night of sleep deprivation (awake for 31 hours). The blue lines indicate males. There was an increase in FBB SUVr for both males and females. An increase in FBB SUVr after a sleep deprived night showed a increased change in negative moods and increase in A42 levels, which could be a risk factor in Alzheimers disease (Shokri-Kojori, 4483). A few things to note: FBB SUVr stands for 18F-florbetaben relative standard uptake (radiotracers), RW stands for rested-wakefulness, and SD stands for chronic sleep deprivation. Reason for Choosing this Article Among hundreds of potential articles, I originally picked this one because it was the most interesting. After diving into the research on the effects of sleep as we age, I learned about the impact of quality of sleep. It was interesting to learn that people living with Alzheimers disease had disruptive sleep and how difficult it was to form and process memories. Relating to my personal life, I realized how difficult it was to focus on tasks and the mental fatigue after sleeping for only 3-4 hours that night before. What drew me in at first on this topic was that the U.S. alone has a high rate of those sleep deprived and the effects of overusing coffee and other medications to stay awake. Not only does sleep impact how well our memory is as we age, I also wondered the impact of sleep deprivation and car accidents. Its illegal to drive under the influence of drugs/alcohol but theres no consequence (legally) driving while sleep deprived (but I digress). Although the field of research t hat hypothesizes the link between sleep deprivation and Alzheimers, I wonder if the quality of sleep could be the future indicator for aging diseases.

Hiroshima, By John Hersey - 1718 Words

â€Å"Hiroshima† was published in late 1946 and written by John Hersey. Hersey was employed by The New Yorker to Japan to explore the aftermath of the first atomic bombing done by the US. On August 6, 1945, the American bomber B-29 dropped the atomic bomb â€Å"Little Boy† over Hiroshima, Japan during WWII. He was able to examine nuclear warfare, the short-term and long-term effects, and the testing of humanity. Hersey’s intent in writing this book was to expose the lives of several survivors of the atomic bomb. Hersey interviews and relays the survivors’ story, exploring their lives before the bomb, the initial reaction, and their lives following the bomb. By examining their lives Hersey offers a different perspective to Americans of that fateful†¦show more content†¦Much of the chapter focuses on the damage and confusion around the city. Reverend Tanimoto immediately began helping a woman and child near him who were injured get to an emergency s ite. It was on his return trip, that he realized the amount of damage done. What he thought was just several bombs dropped possibly damaging a â€Å"patch of the city,† turned out to be the majority of the city. Reverend Tanimoto described mass fire, smoke, and dust. Hatsuyo Nakamura was able to pull herself through the rubble of her home and was hastily able to unbury her children. Upon gathering her uninjured kids, they exited out onto the darkened street confused. They fled to a designated evacuation area passing much destruction and cries of injury. Father William Kleinsurage gathered with the other priests in their vegetable garden. Father Kleinsurage and the other uninjured priests attempted to help remove some of the neighbors out of their ruined homes before gathering a few items from their own ruined house. Dr. Masakazu Fuji was initially trapped by beams in the river, but bravely untangled himself. He was able to catch up with a fellow doctor, where they observed th e damage, and inquired about what could have caused the damage, possibly â€Å"Molotoffano hanakao,† a self-scattering cluster of bombs. He recalled seeing multiple fires and helping the few other hospital staff survivors from the rubble. He also recalled feeling hot air causing

Nursing Health Care Providers and Patients

Question: What tensions do you think you might experience arising from the differing worldviews of administrators, health care providers, and patients? Answer: Difference in the perception of the different group and individuals caused various conflicts in taking decision concerning the health. Highlighting the perception of the healthcare providers, patients and administrators, there view upon the health is totally different. In analyzing the differing worldviews of administrators, it is seen that the pressure arises upon the healthcare providers and the patients as well (Ness, 2013). The administrators are duly responsible for taking the charge of the healthcare support for the patient/s and at the same time, they are also responsible for availing the health care providers for the patients in the hospital or at residence. While observing the administrators, it is also noticed about the preference provided to the type of health cases they manage and priority given to the emergency cases by the managers of the hospital. At this moment, the pressure is all upon the authority for assessing the importance of the health care services provided to the patients. The healthcare providers are responsible after the authority is delegated to them by the administrators (Dettenkofer, 2013). As seen there is a vast differences between the views of individuals upon the common situation, it shall result in the differences of their service providing style. In some of the cases, these differences also become the reason for the conflict between the administrators and healthcare providers. While observing the patients who are availing the services also become the sufferers of this different views and conflicts of the administrators and health care providers (Office, 2015).

The Little Red-Headed Girl free essay sample

â€Å"Just remember that when Charlie Brown was singing to ‘that cute little red headed girl’ it was you! You will be on stage very soon. Love from your friend, Charlie Brown.† These lines hang on a slightly crumpled note card on my bedroom wall, displayed prominently high among various cards, poems, drawings, articles, and pictures. Each time my gaze is drawn to the card, I’m brought back to being five years old and awestruck by those bright stage lights. Every rehearsal of my church’s production of You’re a Good Man, Charlie Brown, I went over to the church and sat in the front row of chairs, scrutinizing the performers at work with my small legs swinging in time with the music and body bent forward in fascination. As the adult actors sang and danced on stage, breathing life and love and humor into the story of a little boy who just wanted to belong and find a home of his own, they unknowingly lead a little girl to find a home of her own.

I participated in school plays and community theatre throughout my childhood, weaving my way through elementary and middle school with a world of color and infinite stories behind me as my escape. Instead of having birthday parties or going to see movies, I worked to save up money in order to go see Broadway shows in San Francisco. Instead of writing short stories or poems like my peers, I wrote short plays and monologues. I reveled in the power of presence, the intoxicating effect of sharing different perceptions of the world with others. Now, as a National Honor Thespian of the International Thespian Society in my second year of Play Productions—the highly selective and accomplished ROP acting class at my high school—I can see how theatre has helped me to grow immensely as an actor, as a student, and most importantly, as a person. It has enabled me to see the individual perceptions we each have of the world and the overlaps between them, as well as create connections between many different areas of life. As such, this fascination with perception has caused my interests to branch out far beyond the arts, from loving neurology and environmental science, to devouring any and all types of literature, to exploring different cultures and religions. I have developed many different outlooks on life as a result, each one that much more developed, valuable, and essential to who I am as a person; and yet, I can’t help but see myself as an actor on stage, leading another little girl or boy with legs swinging in the front row to find his or her home.
