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
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.
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 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.
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.
The idea of phase advance and delay were first proposed by Aschoff and Pittendrigh (1960), but subsequent genetic studies have shown exact genes involved in phase delay and advance occurs due to over or under production of proteins as described in dorsophilia studies. Many knock out studies have shown that disruption of genes involve in circadian rhythm have created arrythmicity in animals. Low-Zeddies and Takahashi (2001), created clock mutants which were arrhythmic when exposed to dark condition. The period of clock mutants were greater when compared to wildtype mice. The mutant also showed higher phase-shifts hours and lower circadian amplitude.
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

Developmental health psychologists - specialists who study the interaction of age, behavior, and health and gerontologists - specialists in the science of aging -- are piecing together the details of diet, exercise, personality and behavior that make it practical to shoot for 80, or even 120. People approaching middle age can expect a bonus of several years of extra living thanks to continuing medical progress against cancer, heart disease and stroke. Specialists in the field of aging, developmental health psychologists, and gerontologist , concentrate their area of study on determining health status over the course of adulthood, and determining the nature and origin of age-related diseases. They are also concerned with describing the effects of health on behavior and describing the effects of behavior on health. The goals of these specialists are: prevention of diseases, preservation of health, and improved quality of health for those suffering from disability and disease.
Sleep is important for many reasons. Nothing can replace a good night of sleep, not even any pills or vitamins. We all have a internal body clock which makes us feel sleepy throughout the day. Our internal body clock controls the "circadian rhythms" in our bodies. These "circadian rhythms" are what let our bodies know when we are sleepy and it also tells us when we suppose to be awake. (UCLA) Our bodies know when it is time to prepare for bed, a hormone called melatonin is released when it is dark outside which causes our bodies to feel tired. (Mann, Denise) It is very important to listen to our bodies. This is something most teens don’t do. During the day a compound called adenosine builds up in our bodies and when we go to sleep our bodies break that adenosine that had been building up throughout the day. Adenosine is a nucleoside that occurs naturally in all cells of the body. Chemically it is 6- amino-9- beta-D- ribofuranosyl-9-H-purine (Mandal). Adenosine is an important hormone in sleep. As soon as we wake up, adenosine builds up in our brains. During the day, as the hours go by it continues to build up...
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.
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

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.
