Human Growth Hormone in Biotechnology
Human growth hormone (GH), also known as somatotrophin, is a protein consisting of 191 amino acids with a molecular weight of ~22,000. Growth hormone is secreted by the pituitary gland, which stimulates growth and cell reproduction. The structure is made up of four helices, which are necessary for functional interaction with the GH receptor. Despite remarkable structural similarities between GH from different species, only human and primate GH may be active in humans.
History of Human Growth Hormone
Growth hormone was first purified from pig and cow pancreas for treatment of type 1 diabetes since the 1920's. However, these types of GH did not function as well in humans, due to greater variation of molecular structure compared to human GH. In 1958, Maurice Raben purified enough GH from human pituitary glands to successfully treat a GH-deficient boy (Raben). In 1960, the National Pituitary Agency was…… [Read More]
On the other hand, there are also many in the medical arena who are of the opinion that this view is too radical and essentially unhelpful. Many doctors consider that a strict ethical view of growth hormone treatment would be unreasonable and unfair to the individuals who must bear the burdens of discrimination... It is not easy to dismiss the profound and understandable distress some children experience because they are short. Such children undeniably are disadvantaged by their condition" (Considerations elated to the Use of ecombinant Human Growth Hormone in Children, 1997)
This important ethical debate is also discussed in various other studies. For example, in a study entitled Moral assessment of growth hormone therapy for children with idiopathic short stature (1997) by Verweij and Kortmann, the authors state that one of the greatest ethical dilemmas facing medicine is the prescription of growth hormone treatment for those children who do…… [Read More]
, 1998). Cognitive functioning, particularly memory performance has been found to be impaired in patients with childhood onset of growth hormone deficiency and HGH replacement therapies have been found to offset this memory impairment (Arwert et al., 2005). Studies have identified a link between improved attention and increases in memory performance in children with growth hormone deficiency (Arwert et al., 2005; Arwert et al., 2006). This is due to the connection between memory capacity and attentional resources.
Growth hormone deficiency that begins in childhood is most often treated with growth hormone supplementation in order to increase body size during adolescence (Nieves-Martinez et al., 2009). Yet recent studies have demonstrated that this treatment directly correlates to improved memory in adulthood. In fact studies have suggested that treatment with growth hormone in child onset deficiencies can in fact prevent learning and memory deficits later in life (Nieves-Martinez, 2009). Childhood onset of growth…… [Read More]
More objectivity is however expected from scientists, but their opinions also vary. Specifically, the opinions of those who support growth hormones and those who reject them are all derived from scientific evidence. This in turn means that the results of scientific research could be manipulated and influenced so that the findings are indicative of the desires of those who initiated the study. In this particular sense, the most pertinent situation is revealed by the beef and dairy producers, who hire their own scientists to lead the research process in the direction desired by them.
Aside from these situations however, the scientists who have conducted studies tend to link various health problems with the growth hormones. Some of the side effects to consuming products with residual matters from growth hormones include the onset of early puberty in girls, an increase in the risk of breast cancer, an increase in the risk…… [Read More]
Counterbalance of Sugar and Fat Content between Insulin and Glucagon
Physical survival depends on the sustained availability and use of energy in the form of adenosine triphosphate or ATP from sufficient levels of a substance, called glucose (owen, 2001). The use of energy depends on the varying levels of activity. Hence, the amount of glucose needed for activity likewise varies each day. Too much or too little glucose is damaging to the body, hence the need for some system to regulate the availability of glucose. It must be present at the precise time and amount that it is needed in order to maintain what is called glucose homeostasis. Homeostasis is the tendency of the body to maintain internal stability and balance through the coordinated responses of body parts to stimuli or conditions (owen).
Insulin and Glucagon
The regulation of glucose availability begins with the pancreas, primarily by…… [Read More]
The circulatory or cardiovascular system is responsible for moving nutrients, wastes and gases between body cells, transporting blood across the whole body and battling disease (Circulatory System). Its principal elements are the heart, numerous blood vessels, and blood.
The heart forms the circulatory system's core. This 2-sided, 4-chambered pump which distributes blood to various arteries comprises of the right and left ventricles, and right and left atria. The ventricles, situated within the heart's lower half, are responsible for pumping blood to the whole body (away from our heart), whilst the atria, situated within the heart's upper half are in charge of receiving blood from different parts of the human body. The right and left ventricles pump de-oxygenated and oxygenated blood, respectively; de-oxygenated blood is pumped to lungs while oxygenated blood is pumped to the remainder of the human body (smith, 2013). These 4 chambers are connected to one another by…… [Read More]
hormones in our agricultural food and the adverse effects it has on the animals and the human consumers. The writer provides an outline of the effect the hormones have both physically and politically on the consumer and the nation's that support the use of hormones. The writer also presents evidence of the health problems hormones are thought to cause as well. There were four sources used to complete this paper.
As the world becomes more crowded the demand for fast growing resources including food increase. The use of growth hormone in cattle has sparked a worldwide controversy as several nation's wrestle with trade organizations mandates against what they believe the hormone treated cows can cause by way of health problems.
The most common hormone used today in the cow industry is Bovine Growth Hormone, which is also referred to as BGH. This hormone is a genetically engineered hormone. It is…… [Read More]
The implant is inserted into the ear and is discarded at slaughter, thus, it does not enter the human food chain (Primer pp). The hormone in the implant is released into the bloodstream very slowly ensuring the concentration of the hormone remains relatively constant and very low (Primer pp). Moreover, the prescribed dosage is the level "which produces the maximum economic response in the animal -- the law of diminishing returns -- so that there is no economic incentive for a farmer to use additional implants," and ensures that the animals taken to slaughter have normal hormone levels (Primer pp). According to the Primer, beef from a bull contains testosterone levels over ten times higher than the amount in beef from a steer that has received hormones for growth promotion (Primer pp). Therefore, since the European beef market is predominately bull-sourced, while the American meat is steer-sourced, American hormone treated…… [Read More]

There is no credible evidence about this statement. It must be noted that it is extremely illegal, not only in the U.S. But also to other or even milk-producing countries, for penicillin to be used specifically in low-level doses in the feed. In fact, penicillin is only use via injection, in concentrated doses, and only if the animals to be injected are sick or with high fever. Penicillin doses are usually once or twice only and the particular animal which has been injected with such medication is separated from other animals and would not be harvested within a certain period. This is to ensure that there is no penicillin residues left in any system or body parts of the animal http://www.maverickranch.com/beef-hormones-mdirf5.htm,2006 para 1).
Moreover, as of latest survey, only 1% (or even less) of the cattle have recorded to ever had any doses of penicillin. Cattleman's Beef…… [Read More]
" This drug has already won approval for use in Europe and the United tates. tudies conducted show that the drug "targets the tumor to control in four areas: in the site where hypersecretion starts, in GH secretion, IGF-1 and in the symptoms associated with the disease (Unknown, 2004)." While the drug has been approved, there are still contraindications to taking it such as a patient who has an irregular or slow heart rate, or blood sugar levels which are either too high or too low.
Although gigantism begins prior to puberty, the "majority of giants eventually demonstrate features of acromegaly, of which the mean age for the onset is within the 3rd decade of life. Even a congenital onset of GH excess has been suggested by linear growth acceleration occurring within the first few months of life in young children with documented gigantism (http://jcem.endojournals.org/cgi/content/full/84/12/4379)."

What is the most likely diagnosis?
John is believed to be suffering from gigantism or acromegaly.
Symptoms of acromegaly
The term 'acromegaly' has its roots in the Greek terms for "enlargement" and "extremities"; these terms reflect one among the ailment's most commonly occurring signs of abnormally expanding feet and hands (Marieb & Hoehn, 2018a; 2018b). Swollen feet and hands typically manifest as an initial sign. Those suffering from the acromegaly notice changes in their shoe or ring sizes, especially shoe width. Slowly, changes in the bone begin to transform their facial features, with their lower jaw and brow protruding, spacing out of the teeth, and enlargement of their nasal bone (Colao et al., 2019).
Abnormal cartilage and bone growth frequently results in arthritis. Tissue thickening can trap nerves and result in the development of carpal tunnel syndrome (CTS) that in turn produces weakening and numbness of hands. Enlargement may also…… [Read More]
Current Health Debate: Cow’s Milk and Human Consumption
So many people grew up hearing repeated slogans and promotions from the dairy industry that were so consistent and repetitive, they seemed almost like a part of life. “Milk does a body good.” “Milk builds strong bones.” “Got Milk?” For decades, no one questioned the power of milk and the necessity of giving children milk. However, in the last ten or so years, the mentality has shifted and a product that was once unquestioned as a staple of human consumption, has now become controversial. This paper examines some of the pros and cons of the dairy industry and milk consumption from a strictly health perspective. The benefits of cow’s milk are examined lucidly, as are the criticisms that the dairy industry and milk consumption receive. Finally, each side’s argument is concluded succinctly, and recommendations for future protocol are presented for consideration.

When discussing and pondering the broader subject of steroids and other substances that aid the body in getting stronger and healthier, one word or term that is likely to come to mind is “anabolic”. However, the use and employment of steroids and supplements has multiple layers and types that must be considered. One of the other terms to consider is ergogenic. Regardless of the type of steroid or body aid, there is an intended and desired effect on performance. There is also the related, yet different, use of what is known as human growth hormone, or HGH. As with all medicines and treatments, there are medical risks when it comes to the use or abuse of steroids of any type, which would include ergogenic. While some people are prone to disavow and condemn the use of steroids and/or supplements across the board, here are a number of findings…… [Read More]
High and Inside
In the Newsweek Magazine article "High and Inside" by Mark Starr, the issue of illegal drug use among professional sports players is given focus. Citing particularly the case of American baseball stars, Starr puts forth the argument that the issue illegal drug use such as subsistence to steroid injections goes beyond the fact that it is illegal -- the bigger issue at hand is that such a system prevails in sports organizations because it is supported and encouraged by everyone in it.
In arguing this primary thesis of the article, Starr exemplifies the case of baseball star Jason Giambi as one of the models of how the proliferation of illegal drug use has made it so common and an imperative requirement for a professional athlete. Chronicling Giambi's career as a professional baseball player, the article details how, just before the peak of his career, he had already…… [Read More]
positive and negative impacts of DNA microarrays, Genetic engineering and cloning on the society, environment and the living beings.
In the past years, people have heard much about the biological revolution and they have seen it coming too. Biology, with its modern discoveries, has not only influenced agriculture, medicine and economy but it has affected the nature of man as well. In today's era, where both, biology and technology are developing at a fast pace it is impossible for anyone to survive without having sufficient knowledge about science. The information related to scientific issues will enable the people to make good choices about their health, environment, surroundings and the society in which they reside. This information also enables the people to logically analyze different inventions and advancements in biology so that they can decide that whether the projected discovery is good for them or not.

e., their use of anabolic steroids (and whether they had ever been offered steroids), their involvement in power sports, appearance and eating problems, and problem behavior. Background information about the participants included their degree of urbanization, parental socioeconomic status and the region to which they belonged.
Analyses of the study's results show that the prevalence of steroid use among Norwegian youth was lower (lifetime use was 0.8% and 12 months prevalence was 0.3%) than in several other Western societies such as the U.S. (2.5% to 7%) and in Australia, Canada, Sweden and South Africa (2% to 3.5%). It also showed that AAS use was first and foremost associated with problem behavior (i.e., drug [marijuana] involvement and aggressive-type conduct problems). Its relation with power sports and appearance came in at second and third place respectively.
The study is, therefore, significant in highlighting the hitherto largely ignored area of problem behavior in…… [Read More]
Animal Production: Biotechnology
Biotechnology has achieved some dramatic advances in recent years in both crop and livestock production. Food production results from the interaction of humans, animals, land and water; to help speed up this process, make it safer and more efficient, biotechnology has been involved. These include transferring a specific gene from one species to another to create a transgenic organism; the production of genetically uniform plants and animals (clones); and the fusing of different types of cells to produce beneficial medical products such as monoclonal antibodies. Today, biotechnology has a number of applications in livestock production. It is being used to hasten animal growth, enhance reproductive capacity, improve animal health and develop new animal products. In 1999, FFTC carried out a regional survey to draw up an inventory of technologies and products which have been developed using biotechnology for livestock production. Some of these are now being applied…… [Read More]
Offered under the same roof are "consultative, diagnostic, and treatment services" which are stated to be provided "by board-certified practitioners in the fields of pulmonary medicine, otolarngology, family medicine and more." (2006)
Smith reports that the laboratories experiencing the most dramatic growth are two which are located the "farthest from the Hillsboro flagship" as they are located in two areas that were "formerly underserved." (2006) Smith additionally reports that the demand is stronger in the areas where the two fastest growing centers are located which supplies "plenty of fuel for expansion."
Smith states that the Sleep Health & Wellness NW is attempting to "fill a gap so that patients who previously were overlooked or not being reached or who fell through the cracks no longer are," she says. "We have no plans to open centers in areas where there are already quality sleep services programs. We only want to go…… [Read More]
In Genentech, Hughes examines the remarkable rise of the Genentech company, which was an industry pioneer in the field of genetic engineering. The basic premise of Hughes’s book is that Genentech radically transformed biotechnology and even made a broader impact beyond the medical technology and science sectors. Themes Hughes addresses in Genentech include the business practices and processes needed to start a radical, innovative firm, particularly one with a business model based on science. Another major theme covered in Genentech is intellectual property, which is a major concern for the pharmaceutical industry, which eventually became heavily and inextricably entrenched in genetic science. Hughes also covers the theme of ethics: especially the conflicts of interest that can arise between the altruistic aims of academia and applied science and the commercial goals of a profit-driven enterprise.
Hughes offers an overview and history of the firm, which was created in 1976 by Herbert…… [Read More]
Bonds than his fellow African-Americans."
Recently, it has come to the attention of the media and others that the drug called, "human growth hormone" (HGH) is being used by some major league baseball players. An article in USA Today (Nightengale, 2007) points out through secondary reporting of data that Rick Ankiel (St. Louis Cardinals), Jay Gibbons (Baltimore Orioles) and Troy Glaus (Blue Jays) have been implicated in the use of HGH. This information was made available because an investigation of a Florida pharmacy by the federal government (reported by Sports Illustrated and the New York Daily News) turned up receipts detailing transactions between those players and the pharmacy.
According to the article, a quantitative piece, by taking HGH (another performance-enhancing substance) players may be able to "avert positive steroid tests." How can they do that? "Taking HGH enables you to take lower doses of anabolic steroids," journalist Bob Nightengale quotes…… [Read More]
aging gracefully. There are eight references used for this paper.
Introduction number of people are obsessed with fighting the affects of aging on the skin and finding ways to age gracefully. It is important to look at methods such as antioxidants, wrinkle fighters and nutritional supplements, as well as aging and tissue/muscle loss and interventions for slowing the aging process in order to gain a better understanding of treatments available.
Free radicals are "highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in normal and pathological processes, and are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging (http://cancerweb.ncl.ac.uk/cgi-bin/omd?query=free+radicals)."
One of the main defenses against free radicals is the proper use of antioxidants.
Researchers theorize that an "increase in some antioxidants - especially those applied to the skin - helps protect…… [Read More]
On the whole, the Academy calls for the abolition of exemption laws and endorses initiatives to educate the public about the medical needs of children (Committee on ioethics)..
While AAP recognizes the importance of religion to people's lives, it also warns physicians and other health care professionals should put the health and welfare of children over religious considerations (Committee on ioethics 1997). It encourages pediatricians to respect parents' decision but not when their religious convictions interfere with medical care necessary to prevent harm, suffering or death. When this happens, pediatricians should seek the authorization of the court to override parental authority. If the threat to a child's life is imminent, the health care practitioner should intervene over parental objections. Securing court authorization should, however, be the last course of action. The health care practitioner should cooperate with the family in applying appropriate palliative care. Even when the securing of court…… [Read More]
Many of the electric gadgets we use today like the cell phones and the home computers were invented in the 80s. Many multinational corporations came into existence in the 80s this spur the growth to a record 3.2% per year (Bellis, 2012). This was the highest nine-year rate in American history. This was occasioned by a number of factors some of which were economic, financial, legislative, and regulatory frameworks. This unprecedented growth led to failure of a number of banking institutions. From these failures, a term "corporate greed" was coined. This essay seeks to enumerate how technology advanced in the 80s (Coppens, 2012).

Similarly, regular exposure to certain types of artificial lighting can have a negative effect on the quality of sleep as well. Research into the comparative health of daytime and nighttime workers has helped establish some of the more specific ways that sleep is important to human health. For example, certain forms of cancer such as breast cancer and colorectal cancer) have been documented at higher rates among nighttime workers Pauley, 2004). As it happens, those forms of cancer are known to be moderated by Melatonin, a hormone secreted by the pineal gland during specific phases of sleep and known to vary in relation to exposure to light Pauley, 2004).
Research on mice revealed that melatonin-related cancers increased when the subjects were exposed to very small levels of light during sleep and also that completely blind human beings have a lower incidence of colorectal cancers than blind people who can perceive…… [Read More]
Salary Cap ? Now Please !
The Steroid era is over, hooray! Now what? Well, Major League aseball, time to catch up with the world of sports. It is time for a salary cap on player earnings. America is in the middle of a recession, unemployment continues to rise and Major League aseball must change with the times. Without shrewd decision making, now, on the part of aseballs' owners, baseball will lose fans. Fans of the game, too long disenfranchised, by eight work stoppages, the most recent nullifying an entire playoffs and World Series. Fans subjected, no matter how willingly, to widespread abuse of steroids, Human Growth Hormone and amphetamines. These same fans will not continue to pour their increasingly slim entertainment budgets into a sport dominated by the few, big spenders, only occasionally challenged by a lesser market. A product of this ilk is ultimately unsustainable. When a fans'…… [Read More]
One of the most pressing problems with the doping incidents is that punishment is so lax in many arenas. The WADA recommends a two-year ban from the sport, but increasing the time could reduce the number of doping incidents. An athlete might be less likely to turn to performance enhancing drugs of any kind if they knew they could face a ban for life, or a five-year or more ban from their chosen sport. Laws regarding the use of banned substances should be reviewed and updated so they are the same for each sport, and so they increase the culpability of the players involved. Since many of these athletes serve as heroes and role models to the children of the world, they owe it to them to come clean, stay clean, and support stricter enforcement in their specific sports. Lance Armstrong, in his comeback maneuver, could serve as a catalyst…… [Read More]
ladies and gentlemen! There is a saying that goes, "Vice seen is better than vice unseen." I mentioned this to relate to a problem we have had with regards to our major league sports players -- the use of performance enhancing drugs "such as anabolic steroids, androstenedione, human growth hormone, erythropoietin, diuretics, creatine and stimulants (Mayo Clinic Staff, 2010)." The problem is not new and has been a challenge because of the gravity of the situation. There is no lack of cases and statistics that show how many major league players have been caught using these performance enhancing drugs, which by the way is banned and illegal. ut my issue is how come these drugs are not allowed? Those who oppose the use of steroids and other performance-enhancing drugs say that the athletes who use them are breaking the rules and getting an unfair advantage over others (Katz, 2008).

Scandal/Controversy in Sports
The following will take a look to see if scandal and controversy benefit sports.
Background of Sports Industry and Scandals
Sports in the U.S. is a multi-billion-dollar industry. Companies try to engage with clients by aligning the services and products they offer with this well-known industry via sports funding and endorsement. The benefit of this involvement has been well-recorded in the sports marketing literature (Hughes and Shank, 2005). The effect on business brands in case a scandal surfaces regarding an athletic supporter like a player, coach, or a team however, is less well-known. Several sports scandals, for instance, the rape case surrounding Kobe Bryant and the University of Colorado recruitment scandal raise very serious questions regarding the effect of sports scandals on amateur and professional athletic institutions, participants, sponsors, as well as other stakeholders.
Whereas conventional corporate sports supporters like Nike maintain omnipresence, several other different kinds…… [Read More]
role of hormones in the control of body fuel/energy mechanism has been appreciated for close to a century (Dzamko & Steinberg,2009). This concept was identified by the groundbreaking findings by the scientists, Banting et al. (1922) that the hormone, insulin could effectively restore euglycaemia. This paper seeks to give an in depth understanding of metabolism by definition and gives the various component of metabolism and finally the hormonal influence of metabolism. This paper looks into the various substrates that are influence the hormonal actions in fuel metabolism, circumstances under which they occur and the various pathways followed during these metabolisms (Becker, 2001). The intermediary compounds are also considered to the effect. In conclusion, the paper discuses the medical conditions that would arise once these hormones fail to act.
Metabolism is a biological process that takes place in living organisms throughout their lives, once metabolism stops the individuals automatically dies. A…… [Read More]
dehydration impacts on human metabolism. In this sense, a short introduction in the issue of deficient water input is followed by delimitating the notions of metabolism and dehydration in terms of definition and classification. Afterwards, focus falls on the possible degrees of dehydration and body mass loss, and their implications for a human body.
According to usan Kleiner, Ph.D., "water is the one essential element to life as we know it" (Rabkin, 2000). It makes up approximately 60% of an individual's body mass. Each human cell, tissue and organ needs it in specific amounts in order to function properly, and nearly every life-sustaining body process requires it, too. Water is present in human muscles, fat cells, blood and even bones, transporting nutrients and oxygen to cells, helping to discard waste products, moistening skin tissues, mouth, eyes and nose, and most importantly, keeping body temperature in check.
Thus, water is unspeakably…… [Read More]
pathological hormonal imbalance effects of follicle stimulating hormone (FH), one first needs to know what FH is. This essay, accordingly, starts off with describing FH before proceeding with a description of how FH imbalance affects the body and providing concise description of the hormone, the target organs, and the cells. The essays also describes the types of receptors that are affected with the imbalance (i.e. The specific cellular effects); the mechanism that is being affected, and the type of receptors that are interfering with the mechanism.
Follicle stimulating hormone (FH)
FH is a hormone found in humans and animals that regulates the growth, development, pubertal maturation, and reproductive processes of the body. It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FH is intimately involved in reproduction by stimulating maturation of germ cells in both males and females and, in females, by initiating follicular growth. By leveling…… [Read More]
Hormone (or endocrine) disruptors interfere with the normal functioning of the endocrine system. They can: mimic a natural hormone and thus fool the body into responding a certain way, interfere with the reception of hormones by hormone receptors, directly alter a hormone and impede its function, cause the body to overproduce or under produce natural hormones, or decrease or increase the number of hormone receptors. These effects are especially potent during prenatal development, when even minute exposure to hormones can severely disrupt the normal development process. Potential hormone disruption effects include abnormalities of the reproductive system, birth defects, behavioral changes, depressed immune systems, and lowered intelligence. (Pettit, 2000, p. 413)

Thyroid Hormone in Carcinoma
The author of this report is asked to review an article and the topic chosen from the acceptable list of topics regards the role and involvement of thyroid hormones in certain disorders. The particular article reviewed for this report focused on the activation of tumor cell proliferation by secretions from the thyroid gland in mice. The specific cancer involved was follicular thyroid carcinoma. Per the requirement of the assignment, the article in question is less than two to three years old. Indeed, it was published last year.
The article starts off by noting that thyroid cancer variants are by far the most common malignancy of the endocrine system in humans. The article notes that the main goal of the research behind the report had the goal of the parallels and similar causes of follicular thyroid carcinoma and thyroid carcinogenesis in general. To prove their…… [Read More]
Finally, the idea that human beings are manifestations of God is profoundly empowering and can in itself foster healing and growth. Murphy urges his readers to use their subconscious minds to become like gods on Earth: to invoke their own healing. The subconscious mind of each person is endowed naturally with the power of God because each person is a manifestation of God. Similarly, the principle of unity underlies the idea that human beings are a manifestation of God. If the universe is unitary then there is no qualitative differences between a human being and God; God is within each person. The idea that human beings are manifestations of God also precludes prejudice or discrimination. If all human beings are manifestations of God then no one person is better or worse than any other. This idea can greatly aid the health care practitioner who has difficulty with ethical issues. This…… [Read More]
Milk from the cow is one of the most versatile and important substances in the human diet as well as in the diets of many animals and in particular in the diet of poultry that are being raised as layers, broilers or for other purposes. The fact that this milk can be processed into many different forms adds to its versatility and provides a wide array of by-products from which specialized uses can be determined. Understanding the basic array of materials that can be obtained from processing milk is the first step in understanding how those products can be used in the diets of poultry. The next step of understanding the relationship between dairy by-products and the benefits they can provide to poultry comes through examining the nutritional content of those by-products for the feeding and development of poultry. As these two explanations are provided it becomes evident in…… [Read More]
Farms that contain the r-BST free labeling are typically from single farms that do their own proprietary retail packaging.
The study concluded that there were no differences in antibiotic levels in the milk samples. The purpose of the study stated, "the objective of this study was to compare these endpoints for conventional, rbST-free, and organic milk.," (Vicini, Etherton, & Etherton et al., p. 1199). By the time conclusions were drawn, the topic of rBST and organic milk, as stated in the research objectives, had been completely abandoned and replaced by conclusions regarding antibiotics, which are required to be zero for any milk, regardless of origin, that ends up on retail shelves.
The only studies that are provided to the public, and which are the basis of policy decisions, are highly suspect due to the financial interests between Monsanto and the research laboratory. The sampling techniques used, invalidate the conclusions drawn.…… [Read More]
The success was remarkable, according to the researchers: Even muscles that had already lost half of its mass, recovered visible. (Leppanen et al. p5549-65) At the same time, the mice survived for several weeks longer than their untreated counterparts and also developed a healthy appetite again. (Mantovani, p296) The new study is therefore interesting in two respects: First, it demonstrates that the muscle loss at least in animal models in fact, affects the chances of survival, and secondly, it shows a way, may be how to prevent this degradation, and even reversed. (Bruera et al. p857)
Muscle atrophy is a medical term that refers to the decrease in the size of skeletal muscle, losing muscle strength because of the strength of muscle is related to its mass. (Burnfoot, p323-34)

S. Congress that the prospects of stem cell research were so vast that it could touch all the realm of medicine (Connor 2000). An unlimited source of embryonic stem cells will solve the problem of shortage of transplants. Embryonic stem cells will save lives by curing generative diseases of the brain, hepatitis, diabetes, leukemia, rheumatoid arthritis, muscular dystrophy and cystic fibrosis and diseases of the heart and kidneys. ut current laws restrict the use of stems cells on embryos less than 14 days old and for correcting fertility, reproduction or congenital disorders. The restriction is grounded in the belief that the embryo is a potential human being from the moment of conception. It thus possesses a soul and a dignity just like any other viable person (Connor). Previous scientific research presented evidence that genetically engineering cells could partly repair a defective immune system (Travis 2002). Two new studies bolstered this…… [Read More]
Organ Systems: The Pituitary Gland
The pituitary gland, according to Davies (2007), "is a pea-sized endocrine gland at the base of the brain," linked to the hypothalamus by the infundibulum. It is divided into several parts; i.e. The anterior lobe (front part) and the posterior lobe (back part). The anterior lobe secretes seven hormones that are essentially responsible for the regulation of a number of activities that take place in the human body - from reproduction to growth. Of the seven, five are tropic hormones (induce other glands to secrete hormones). The pituitary gland secretes only two hormones. The targets and effects of the nine are presented in the table below.

People can exercise their free choice at the grocery store by choosing organic foods, although because of generally higher costs of organic products, this will not be a solution for everyone. People in lower socioeconomic groups often get food at discount chains or even food pantries where organics are not even a choice at all.
There is no incentive for makers of agricultural chemicals to modify their products in response to charges about obesogens. As the documentary films the Future of Food and King Corn pointed out, the use of pesticides is very big business. Though detrimental effects of pesticides and genetically-modified seeds and food have been shown, further research is needed to prove the link between pesticides and genetic modifications that lead to obesity in infants and children. When and if that link is proven, the public will have to demand that the government take action. Consumer advocate organizations…… [Read More]
Role of Secondary (Hormone) Messengers in the Process of Metabolism in Cellular Communication
As the primary unit of human living, cells have multi-function tasks that need to be accomplished spontaneously within the body, especially if the body needs to accomplish many tasks and activities at the same time. That is why cells have an elaborate form of communication, which is primarily chemical and biological in nature. The biochemical cellular communication in cells coordinates all tasks that are essential for the survival of the human body. These tasks include cell communication for motion and active transport of substances within the body; biosynthesis, or the production of chemical substances as a result of the biological activities of the cell; cell reproduction, growth, and death; and signal amplification, which is one of the primary phases in the process of cellular communication.
The signal amplification phase, apart from acting as an 'intermediary' phase towards…… [Read More]
prokaryotes consist of millions of genetically distinct unicellular organisms. A procaryotic cell has five essential structural components: a genome (DNA), ribosomes, cell membrane, cell wall, and some sort of surface layer which may or may not be an inherent part of the wall (1). Functional aspects of procaryotic cells are related directly to the structure and organization of the macromolecules in their cell make-up, i.e., DNA, RNA, phospholipids, proteins and polysaccharides. Diversity within the primary structure of these molecules accounts for the diversity that exists among procaryotes (1). Identifiable groups of prokaryotes are assembled based on easily observed phenotypic characteristics such as Gram stain, morphology (rods, cocci, etc.), motility, structural features (e.g. spores, filaments, sheaths, appendages, etc.), and on distinguishing physiological features (e.g. anoxygenic photosynthesis, anaerobiasis, methanogenesis, lithotrophy, etc.). Prokaryotes are commonly known as bacteria, and it is estimated that bacteria have been around for at least 3.5 billion years…… [Read More]
Anti-Aging Medicine? Include Abstract eferences scholarly
This is a review of the article titled "Is There an Antiaging Medicine?" which was written by obert N. Butler, Michael Fossel, S. Mitchell Harman, Christopher B. Heward, S. Jay Olshansky, Thomas T. Perls, David J. othman, Sheila M. othman, Huber . Warner, Michael D. West, and Woodring E. Wright. The article was published in the volume 57A, issue no. 9 of the Journal of Gerontology: Biological Sciences in the year 2002 from pages B333-B338. The journal is published by the Gerontological Society of America.
Anti-aging medicine refers to any form of intervention that is given to delay the development of pathology that depends on the person's age and any other changes that are related to age that are not necessarily diseases. All what are there is false claims and bogus remedies which are not known to work. Slowing down the process of aging…… [Read More]

Neuroendocrine tumors (NE) are neoplasms characterized by tissue immunoreactivity for neuroendocrine differentiation markers, appearance as a small mass that can be off white to yellow often in submucosa and prevalence throughout the body but typically found in the intestine or lungs (Oberg2011). he tumors can be malignant and are typically detected through hormone markers in a first diagnosis (Arnold 2003). Because of the diffuse nature of this type of tumor, detecting and imaging NEs requires scanning and typically requires a contrast agent to detect the location of tumors in tissue (an 2011). Many NE cells possess an overexpression of somatostatin receptors on their surface (Kwekkeboom 2005, VenEssen 2007). Somatostatin receptors are cell surface proteins that bind to somatostatin, a growth hormone inhibiting hormone that regulates the endocrine system and affects neurotransmission and cell proliferation (Florio 2002). he overexpressed somatostatin receptors can be used to both…… [Read More]
Ironically, only 1% of the world's fresh water is readily accessible for direct human use. Translated into something we can understand readily: one American taking a 5-minute shower uses more water than the typical person living in a developing country slum uses in an entire day -- and most Americans take far longer than 5-minute showers. This is a crisis that must be addressed, if it is not, over the next two decades the average supply of water per person will drop by over 30%, condemning millions of people and animals to death (Atlas of a Thirsty Planet).
This assignment opened my eyes to a new way of looking at food -- I will be unable to go into a grocery store and look at rows and rows of perfect fruits and vegetables; knowing that half are thrown out while people starve. In the same manner, knowing that each American…… [Read More]
Bone Health in Children
A healthy, well-balanced diet is essential for normal bone development in otherwise healthy children (Prentice et al., 2006). Sufficient consumption of proteins, carbohydrates, and fats help to build and maintain bones and supporting structures consisting of collagen, glycoproteins, and proteoglycans. The bone mineral itself consists of calcium and phosphate crystals, but magnesium and zinc are also required. A number of ions are essential, including copper, manganese, and citrate, while vitamins also play an important role, especially vitamin D, C, and K. These minerals, ions, and vitamins are required for the proper development and maintenance of healthy bone mineral and supporting structures.
Genetic studies have provided conclusive evidence of which factors play a role in bone development (Prentice et al., 2006). Naturally-occurring mutations in the vitamin D-receptor, low-density lipoprotein receptor-related protein 5, insulin-like growth factor, and a number of other genes encoding growth hormones, revealed…… [Read More]
Proteinaceous Infectious Particles"
Recent cases of Mad Cow Disease have focused the public attention on prion diseases and the small proteins that are believed to cause them. The scientific community has been slow to recognize this mechanism of disease, since prion-caused encephalopathies can demonstrate diverse symptoms, and share characteristics with other disorders, such as dementia.
Prions, as the acronym (Proteinaceous Infectious Particles) suggests, are small proteins that are typically expressed in brain tissue, and may exist in a normal or abnormal shape. The prion protein is encoded by a gene found on the human chromosome 20. Usually, the prion protein is translated in neural tissue, folds into its normal conformation, carries out its cellular role, and is eventually degraded by enzymes. The abnormal prion, however, folds differently from its normal counterpart. This different shape makes it more difficult to degrade, and leads to the brain damage that is seen…… [Read More]
One might consider fibromyalgia to be one of the most confounding conditions around today. It is debilitating. It results in several quality of life issues. The confounding aspect of this condition is that it is difficult to diagnose. It is also difficult to treat. Most treatment modalities today recourse to treating one or more specific symptoms -- but there is no treatment that can comprehensively treat all the symptoms. (NIAMS, 2004) More holistic treatment modes however, are being researched, explored and considered. Fibromyalgia often presents symptoms of other diseases. Essentially therefore, fibromyalgia is characterized by widespread pain that cannot be localized to any part of the body. It is also associated with fatigue and other specific (though not necessarily widespread) symptoms that will be discussed later in this work.
Fibromyalgia syndrome is often referred to in its abbreviation FMS. Some of the symptoms (though not all) enjoy significant overlap…… [Read More]
In here, the teens are seeking for adventure and experiment with different ideas. During this time, the adolescent battles over his own set of values vs. The set established by parents and other adult figures. They also begin to take on more control of educational and vocational pursuits and advantages. It is during this time that adolescents' self-dependence and a sense of responsibility become apparent, along with their quest to contribute to society and find their place in it.
With the way they respond to peer pressure, social demands and other factors that lead to irresponsible actions, teens should know their consequences. Excessive drinking, smoking and drugs can cause damage to vital organs including liver, lungs, heart and pancreas. It can also cause death, not only of the person who consumed such but of a third party as well. Drinking while driving may cause an accident or worse, even death…… [Read More]
The human stress response is influenced by a host of personality characteristics and life experiences that cannot be duplicated in animal studies. (Anisman & Merali, 1999, p. 241)
Because stressful stimuli often elicit cortisol secretion, some researchers have proposed the use of cortisol levels as an index of the stress response. (Anisman & Merali, 1999, p. 241)
esearchers have indicated that human and animal anxiety/stress profiles differ along cognitive behavioral lines. These findings are based on the idea that anxiety is understood as an affective (emotional) state in humans (Wall & Messier, 2001). esearch was conducted regarding stress utilizing hesus monkeys. The study uses a hormone Adrenocorticotropic hormone (ACTH) which was injected into half of the pregnant hesus monkeys in the study. ACTH is secreted from the anterior pituitary in response to corticotropin-releasing hormone from the hypothalamus. It is secreted in response to various types of stress. Blood samples were…… [Read More]
The meat comes from a local independent packing company that doesn't buy beef that has been injected with growth hormones; the buns are from a bakery in Pueblo, Colorado; and two hundred pounds of potatoes are "peeled every morning in the kitchen and then sliced with an old crank-operated contraption." The cooks make $10 an hour, and all other employees earn $8.00 an hour. hen asked why the Conway family provides health insurance for all full time employees, Rich Conway said, "e want to have healthy employees."
The author also calls for changes in the way the U.S. Congress oversees advertising, asserting on page 262 that Congress "should immediately ban all advertisements aimed at children that promote foods high in fat and sugar." The justification for that ban would be that 30 years ago, congress banned cigarette ads from TV and radio, because of course cigarettes were seen as a…… [Read More]
Farris (1990) cites Glasser's Control Theory as a foundation for developing activities to motivate adolescent learners. Briefly this theory asserts humans have five basic needs: the need for survival, belonging, power, freedom and fun. Effective teachers recognize and respond to students' needs and a critical part of that response lies in helping students accept and maintain that essential control.
Farris (1990) proposes possible classroom responses designed to meet these needs. To satisfy the need to belong a teacher should create a classroom with an accepting atmosphere, create a sense of ownership, recognize student's attempts to be accepted, praise students' performance, teach using groups, and discipline or reprimand in private whenever possible to avoid humiliating students. The need for freedom can be addressed by involving students in rule making, providing opportunities for free expression, encouraging creativity in assignments, and possibly consider eliminating assigned seating. The need for power can be addressed…… [Read More]
Homeostasis, according to Nirmalan and Nirmalan (2017), is the propensity for living organisms to maintain relative stability in the internal environment. Homeostasis is made possible through the cooperation of several regulatory mechanisms and separate sub-systems which make up the normal physiology of a living organism (Nirmalan & Nirmalan, 2017). During critical illnesses internal or external stress can make an attempt at interfering with the self-regulation systems beyond what is considered as normal range in physiology. According to Palaparthi and Med (2017), the word homeostasis is derived from two Greek words i.e. ‘homeo’ (stands for similar) and ‘stasis’ (standing for stable). Homeostasis is the balance, equilibrium and the stability of the body or of the cell (Palaparthi & Med, 2017). Living organisms exhibit this character. The process of maintaining stability in the internal environment necessitates occasional internal adjustments as the environmental conditions continue to change outside and inside the…… [Read More]
As has been seen in this essay, leptin plays a very important role in not only obesity issues but also related issues. While the results of clinical trials have produced mixed results, there is however room for additional work in assessing the role of leptin, especially that which is administered from without the body. A continued process of discovery associated with leptin is crucial. Its effects on several obesity-related diseases need to be understood in the interest of the public health.

Abortion: Ethical and Political Issues of RU 486
Abortion is a totally unacceptable, cruel and unethical practice and should be considered illegal except under some special cases and medical circumstances that indicate a danger to the mother. Our judicial system must consider the ethical and moral aspects of abortion as an intrinsic part of the problem when approaching this social issue. Even from the practical prospective the abortion pill RU486 has not been a breakthrough and instead of making abortion a private and safe method it has only increased the physical discomfort and the psychological ordeal for the woman.
Abortion is the one of the most debated social issues of this century. The controversy as to the right that man has over the life of a baby in the fetus and in controlling its entry into the world is a much-debated topic. Abortion is nothing but putting an end to…… [Read More]
" (Klotter, 2001) Additionally, salt functions as an extraction agent for excess acidity in the body which are in the form of "hydrogen ions, and oxidants from ATP production" from cells. (Klotter, 2001; paraphrased) Morris (2008) states that in order for the body to become adequately hydrated the individual should replace fluid lost by perspiration when exercising and should always drink water prior to consuming food. The ideal water intake for someone who exercises is stated to be as follows: "Drink 17 ounces of water 2 hours before the activity and weigh yourself right before you exercise. While you exercise, drink 6-10 oz. every 15-20 minutes." (Morris, 2008)

A history of a typical American meal
When a typical consumer purchases a rib-eye steak for dinner, he or she will pay far less than his or her grandfather did for the same cut of meat. This is because of the efficiencies generated by the commercial meat industry. While the cow will begin its life in a manner similar to that of cows of the past -- by the side of his or her mother on a ranch -- that will quickly change. "Cows raised on grass simply take longer to reach slaughter weight than cows raised on a richer diet, and the modern meat industry has devoted itself to shortening a beef calf's allotted time on earth" (Pollan 2002). On a factory farm, cows are quickly weaned from their mother and fed a corn-based diet or 'finished' on corn while they are held in pens. Instead of…… [Read More]
By attempting to suppress debate about the subject, Monsanto created and subsequently reinforced the notion that BGH is a harmful substance. Eventually, the company was forced to exit the business, because of the damage they did to the product's reputation.
There are times when good ethics demands that a new product innovation be dropped, and this was likely one of those times. By pursuing profit instead, Monsanto has put the health of many Americans at risk and called even more attention to their unethical practices.

53). He points out that four countries (in 1917) -- England, France, Germany, and the United States -- own 80 per cent of the world's finance capital; thus, in his view, the whole rest of the world is subjugated, that is, indebted to and tributary to those four "international banker countries."
Where once monopolists exported goods to other countries to make a profit, now they export finance capital. This is another symptom of the imperialistic stage of capitalism -- what to do with excess wealth? Lenin states that it would not be capitalism if the excess wealth were used to improve the quality of life for the millions of people who are still underfed and leading lives of misery. Instead, the capital is exported to "backward" countries and used to make more profits. In backward countries (now called developing nations) where there is a shortage of capital, labor is cheap,…… [Read More]
Organic Agriculture, Gardening and Retail
Global Emerging Industry
The purpose of this work is to explore the feasibility of entering into the industry of either retail of organic food or perhaps the possible agricultural realm of the organic food industry. This work will examine all aspects of the organic food industry in brief as well as exploring the marketing possibilities as well as the financial report of a sampling of those doing business within this industry.
Organic food products are growing in terms of customer demand and that is good news for those in the business and indeed for those who desire to see this industry expand which will offer more choices in health wise consumption to consumers as well as providing employment for those who may be otherwise considered non-employable due to educational limitations and finally this industry may very well provide at least some of the…… [Read More]
