Melatonin And The Pineal Gland
Set deep in our brains is a tiny gland called the pineal gland. This tiny gland is in charge of the endocrine system, the glandular system that controls most of our bodily functions. The pineal runs our Œbody clocks', and it produces melatonin; the hormone that may prove to be the biggest medical discovery since penicilin, and the key to controlling the aging process. The pineal gland controls such functions as our sleeping cycle and the change of body temperature that we undergo with the changing seasons. It tells animals when to migrate north and south, and when to grow or shed heavy coats. By slowing down and speeding up their metabolisms, it tells them when to fatten up for hibernation, and when to wake up from hibernation in the spring.
Melatonin is the hormone that controls not only when we feel sleepy, but the rate at which we age, when we go through puberty, and how well our immune systems fend off diseases. Being set in the middle of our brains, the pineal gland has no direct access to sunlight. Our eyes send it a message of how much sunlight they see, and when it's dark. The sunlight prohibits the gland from producing melatonin, so at night, when there's no sun, the sleep-inducing hormone is released into our bodies. Because of the pineal gland and melatonin, humans have known to sleep at night and wake during the day since long before the age of alarm clocks.
Humans don't produce melatotin right from birth; it is transfered in utero to babies through the placenta. For their first few days of life, babies still have to receive it from breast milk. Our levels of melatonin peak during childhood, then decrease at the beginning of puberty, so that other hormones can take control of our bodies. As we get older, the amount of melatonin we produce continues to decrease until at age 60, we produce about half as much as we did at age 20. With the rapid decrease from about age 50 on, the effects of old age quickly become more visible and physically evident. With what scientists have recently discovered, we may very soon be able to harness melatonin to slow down aging, fend off disease, and keep us feeling generally healthy and energetic; not to mention the things melatonin can do for us right now like curing insomnia and regulating sleeping patterns, eliminating the effects of jet-lag, and relieving every day stress.
Melatonin is known as the "regulator of regulators", because it sends out
People often find themselves as part of a collective, following society's norms and may find oneself in places where feeling constrained by the rules and will act out to be unconstrained, as a result people are branded as nuisances or troublemakers. In the novel One Flew Over The Cuckoo's Nest, the author Ken Kesey conveys the attempt McMurphy makes to live unconstrained by the authority of Nurse Ratched. The story is very one sided and helps create an understanding for those troublemakers who are look down on in hopes of shifting ingrained ideals. The Significance of McMurphy's struggles lies in the importance placed on individuality and liberty. If McMurphy had not opposed fear and autocratic authority of Nurse Ratched nothing would have gotten better on the ward the men would still feel fear. and unnerved by a possibility of freedom. “...Then, just as she's rolling along at her biggest and meanest, McMurphy steps out of the latrine ... holding that towel around his hips-stops her dead! ” In the novel McMurphy shows little signs like this to combat thee Nurse. His defiance of her system included
In the first half of the classic novel One Flew Over the Cuckoos Nest, author Ken Kesey uses many themes, symbols, and imagery to illustrate the reality of the lives of a group of mental patients. The story takes place during the 1950s in an Oregon psychiatric hospital and is narrated by a patient on the ward named Chief Bromden. When the novel’s protagonist, Randle P. McMurphy enters the confines of a mental institution from a prison farm, the rules inflicted by the Big Nurse begin to change. Chaos and disruption commence throughout the standard and regular flow of the hospital life, altering the well-established routines due to the threat that McMurphy opposes on the ward. Obviously, it becomes evident that Kesey will convey many viewpoints throughout the course of the story, however, I strongly believe that a recurring theme can be singled out. The main theme behind One Flew Over the Cuckoo's Nest is the idea of freedom and confinement and how it affects human behaviour.
The Makah people indigenous to the Pacific Northwest have a very close and long standing cultural bond to the ocean. This cultural bond is displayed in various forms such as their artwork, history, and lore. One key aspect of their culture has come scrutiny within the past twenty years—whaling. Since 1855, the Makah people have legally held the right to whale in designated waters around their reservation. In the 1920’s, the Makah decided to halt whaling due to a dwindling population of the whales. In 1986, the International Whaling Commission enacted a global moratorium on commercial whaling with two exceptions being scientific research and aboriginal subsistence. In the mid 1990’s the Makah people decided to resume their whaling practices with rising whale populations and successfully killed their first whale in roughly 70 years in 1999. This has led to much backlash from domestic governmental agencies and NGOs alike. Thus the problem lies in the question as to whether the Makah people should legally be allowed to whale with the answer being a resounding no. There many issues domestic and international issues with the continuation of the Makah people whaling with the most important being: other previously whaling states seeing the United States ‘pardon’ cultural whaling and failing to see the importance of the global whaling moratorium in effect, the possible discovery of a small population of rare resident whales in the area, and the immorality of slaughtering a highly sentient being.
The fundamental theme in Ken Kesey’s One Flew Over the Cuckoo’s Nest involves society's destruction of individuality. People who refuse to conform to the social standards face ridicule and judgment. Kesey develops this theme through his use of mechanical imagery, metaphors, and symbolism. The novel takes place in a mental hospital, the narrator, Chief is a patient in the ward who suffers from vivid hallucinates. When McMurphy, a spirited character arrives at the ward he begins to question the humility of the hospital, his criticisms of the hospital spark a rebellion amongst the other patients. McMurphy teaches the others to think and speak as individuals and to be themselves despite others judgements. As Nurse Ratched sees the usually powerless patients find power in numbers she decides their leader, McMurphy must be eliminated if she wants to maintain control. She eventually has McMurphy lobotomized leaving him in a vegetable state. In the end Chief runs away from the hospital deciding to no longer live his life under the oppressive rule of doctors and nurses. After being inspired by McMurphy’s free thinking ways Chief decides that living a life dictated by society is not a quality life.

The focus of health care is and has always been, practicing good hygiene, living a healthy lifestyle, and having a positive attitude reduces the chance of getting ill. Although there is not much prevention we can take for some of the diseases but we can certainly practice good hand hygiene to prevent infection and its ill effects. Research proves that hand washing is surely the most easy and effective way to prevent infection in health care. The question for this research: Is Hand washing an effective way to prevent infection in health care? It led to the conclusion that due to the high acuity, high patient: staff ratio, and lack of re evaluation certain units in the health care facilities cannot adhere to correct hand washing guidelines. Hand
One of the most prominent marine hunting nations in the world is the Japanese. Commercial Whaling has been a big part of Japan’s industry and economy, since the 17th century, it has been one of the main sources of food for the Japanese people. During the 1900s, whales became an important part of the Japanese diet because it provided a lot of protein and was accessible to Japan during World War II when food was scarce. The year with the highest number of whales caught by Japan was in 1962 when 226,000 tons of whale meat was sold nationwide. In 1982 a decision was made by the International Whaling Commission that would ban commercial whaling in Japan, this was known as the moratorium that was finally enforced in 1986. Unfortunately the moratorium was only successful for a couple of years; shortly after Japan was able to hunt whales for :scientific research” which did not violate...
The quest to gain international agreement on ethical and legal norms for regulation of whaling has had a long and troubled history. The modern phase of global concern over whaling ethics and conservationist management originated in 1946, when the International Convention on Regulation of Whaling was signed. Thus the International Whaling Commission was created. The International Whaling Commission was designed to control and mandate the whaling industry. From it’s beginning as simply a whalers club with scientific guidance, to the current day conservationist body; the IWC has undergone many revisions and transformations since the start. In 1982 the IWC voted to implement a “pause” on commercial whaling (which is still in effect today). Which major whaling nations, Japan, Norway, Peru, and the Soviet Union (later replaced by Russia) lodged formal objections, due to the fact that the moratorium was not based on advice from the Scientific Committee. One major disappointment of this regulation was due the fact that the moratorium only applies to commercial whaling. Thus, whaling under scientific-research and aboriginal-subsistence is still allowed. Japan and other countries have continued their hunt in the Southern Ocean Whale Sanctuary under the “scientific research” loophole. However, environmental activist groups openly dispute the claims and continue their rally to end the whaling industry for good.
After analyzing the discourse community of law and the detailed process lawyers take in order to write an effective appeals brief, one can see that lawyers have a very specific and unique way of communicating that includes certain jargon unfamiliar and possibly incomprehensible to the general public. Although writing an appeal brief is only one aspect of many that government prosecuting attorneys such as Kenny Elser face in their jobs on a daily basis, it is also a very necessary job because not only is it used by a single discourse community in the law profession but utilized by the discourse community of law as a whole.

In addition, healthcare workers’ handwashing technique differs from the one you use at home. It is “important that all surfaces of the hands are cleaned thoroughly to dislodge and wash away pathogens” (Burton & Ludwig, 2015, pg. 261). The spread of pathogens in a healthcare setting happens with high likelihood. Therefore, it is imperative to wash one’s hands in the following situations. First, upon entering the patient’s room, secondly, anytime your hands are visibly dirty, third, between caring for two patients in the same room, forth, immediately after removing your gloves, and finally after touching body fluids, secretions, excretions, or contaminated
While looking through articles on the Academic Search Premier on D2L, I found an International Whaling Commission article by Mark Simmonds that caught my eye. The article comments on the practice of whaling and a proposal before the IWC that could possibly lead to the resumption of commercial whaling, if this proposal passes it will mean the time and millions of dollars spent over the years on conservation will be thrown out. Simmonds states, “Even with the memorandum, hundreds of whales are killed every year” (22). This is because the IWC allows nations to grant special permits to themselves ...
Historical archives record famous short sleepers and notable insomniacs—some accounts reliable, some not. When Benjamin Franklin counseled, “Early to bed, early to rise, makes a man healthy, wealthy, and wise,” he was using sleep habits to symbolize his pragmatism. Important public policy issues have arisen in our modern 24-hour society, where it is crucial to weigh the value of sleep versus wakefulness. Scientific knowledge about sleep is currently insufficient to resolve the political and academic debates raging about how much and when people should sleep. These issues affect almost everybody, from the shift worker to the international traveler, from the physician to the policy maker, from the anthropologist to the student preparing for an exam.
This reflected light passes through the lens and falls on to the retina of the eye. Here, the light induces nerve impulses that travel through the optic nerve to the brain, where it makes an image of the object, and then that image is passed on to muscles and glands.The eye is well protected. It lies within a bony socket of the skull. The eyelids guard it in front. They blink an average of once every six seconds. This washes the eye with the salty secretion from the tear, or lachrymal, glands.
