Immune System the Functions of the Immune

Immune System

The functions of the immune system have been discussed in detail by the preceding paper. It also puts light on the functions of the complement system and various cells of the immune system. Apart from that, it also analyzes the impact of Type 1 Diabetes mellitus on the functioning of the immune system.

The immune system can be defined as a complex network of a number of tissues, organs and cells that work in an integrated manner in order protect the body from the attacks of foreign invaders. These invaders generally include the pathogens, such as viruses, bacteria, worms and fungi etcetera and the microbes. ("Understanding the," 2003) The functions of the immune system can be classified as non-specific or general and specific. The non-specific functions of the immune system include the barriers to entry, discharge of protective proteins, phagocytes, use of natural killer cells and the inflammatory…… [Read More]

Immune System How Negative Emotions

Thus, continued chronic stress can lead to a variety of health issues, and one of those is cancer, because the weakened immune system cannot fight off the cancerous cells, allowing them to grow more rapidly and unchecked.

This build up of the immune system to chronic stress can also lead to many other conditions, such as tolerance and dependency on many types of drugs. For example, a person under chronic stress who relies on aspirin or other pain relievers may develop a tolerance to the drugs, requiring more drugs to gain the same affect as fewer drug dosages before. Thus, the immune system in high gear can build up tolerances to drugs and other medications in its continued effort to protect the body and fight stress and anxiety. This is also dangerous, because the patient must take more drugs to gain the same result, and some drugs may simply become…… [Read More]

Relationship Between Stress and the Immune System

Immune System and Stress

How quickly a deceased human (or animal) body breaks down is testament to how well the immune system works. While a body is alive, the immune system protects the body at every living moment from bacteria and other foreign invaders. The immune system is a complex system of cells -- which have varying functions -- and generated at discreet regions of the body, a circulatory system -- the lymphatic system -- that feeds of and into the blood circulatory system and lymph nodes that act as effective filters and stores of foreign bodies marked for destruction by antibody action. Most of the time, the immune system protects the body. ut on rare occasions we might need outside help: this is when he system does not "figure out" the invasion and the body has to be coaxed into producing antibodies by inoculation with weaker forms of the…… [Read More]

How HIV Attacks the Immune System

HIV stands for human immunodeficiency virus, which can lead to AIDS (acquired immunodeficiency syndrome). This is a virus that, according to Centers for Disease Control and Prevention (CDC), that spreads through a person's body and attacks certain specific cells, called "CD4" of "T" cells. If the virus spreads sufficiently throughout the body then it becomes very difficult for the body to fight off infections -- and eventually, the deeper the virus penetrates the body the greater the chances of the person becoming infected with AIDS. This paper reviews the most recent medical care that can (in many cases) keep the virus from spreading; it also reviews the way in which a person can become infected with HIV and the stages that HIV goes through.

Immune Biopsychology Interactions of the

An interesting view of the immune system with particular implications for the current review and collation of information is provided by the field of computer science. The immune system makes many series of continual trade-offs, distributing resources in a way that necessarily leaves certain vulnerabilities in the system as a whole while providing greater comprehensiveness in coverage and protection when necessary (Hofmeyr 1997). This makes the immune system an adaptive and continually evolving and self-improving system; with little outside direction it is capable of assessing changing needs, and altering itself not only in particular instances but even in some of its general responses in order to provide greater long-term efficacy for the task of protecting the human organism from disease (Hofmeyr 1997). This view of the immune system as a contained and self-informing system is not entirely accurate, but it is a very useful perspective for our purposes herein.

Immune Responses

IgE

Immunoglobulin E (IgE) is an antibody that helps in regulating the destruction of harmful cells and antigens within the human body. If a 4-year-old patient is being prescribed this medication it is intended to help in decreasing the brutal symptoms of asthma and other ailments such as rhinitis.

IgE is one of the several kinds of immunoglobulin's, also known as antibodies, that is contained within the human immune system. IgE's encounter the allergen, or virus within the body and are programmed to destroy it. This process is completed by the IgE antibodies when they signal the basophile or mast cells to release a histamine or other damaging chemical to the invading antibody. In the war to provide immunity to the body IgE is a main weapon that can neutralize those pathogens that are consistent with an asthma patient.

Each type of IgE has a specific code or mission that…… [Read More]

There are many different explanations for the way in which thoughts are formed, impressions are made, and perceptions are shaped, and though the modern era has provided an abundance of objective observation and experimentation in the area this has not settled the issue. Far from it, in fact; if anything, the growth of reliable research and evidence in this area has contributed to a divergence of theories that, at least in some aspects, currently appear to be mutually exclusive. The theories of psychologists and neuroscientists at times seem especially opposed to each other, and it will require deeper investigations and the uncovering of more substantial evidence to truly bring many of these well-founded theories in line with each other.

Whey Protein and the Immune

Whey protein includes a range of fractions such as alpha-lactalbumin and beta-lactoglobulin and the minor fractions such as lactoferrin and serum proteins. These fractions are established immuneenhancing components" ("Whey and HIV / AIDS").

In addition, recent research has shown that whey protein has a rich concentration of cysteine, which boosts glutathione (GSH) production. "GSH is an anti-oxidant required for a healthy immune system" ("Benefits of Whey").

The concentration of GSH regulates the body's antioxidant and immune defense system. Other protein sources simply do not have the ability to boost GSH production, as whey protein does. It is this GSH production boost that optimizes many aspects of the immune function. An abundance of cysteine to the liver, through the consumption of whey protein, will boost muscle glutamine production and help maintain immune competence ("Whey and HIV / AIDS").

In the end, proteins are a necessary building block of life. Without protein,…… [Read More]

e. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying upon the reserve capacity of the heart to provide the endurance needed to perform such activities. If an elderly person does not engage in some sort of endurance-based activities, he or she will not have the cardiac reserve capacity needed for daily tasks. More importantly, diminished capacity may not counteract illnesses or diseases. Although strength-based activities help the cardiac reserve, it may not benefit the skeletal system. "While resistance exercise promotes fiber hypertrophy in skeletal muscles, the explosive power of…… [Read More]

Lymphatic System Is a Sub-System of the

Lymphatic system is a sub-system of the circulatory system. It contains a network of nodes, or vessels and filters, which remove toxins from the body. The role of the lymphatic system in the homeostasis of the body is that it serves as the primary drainage for all of the body's other systems, removing all toxins and excess fluids. It is a major defense against disease and also helps carry nutrients throughout the body.

The lymphatic system does not circulate blood. Lymph is its primary fluid and is formed from fluids surround cells throughout the body and passed into lymph vessels. If this fluid were not removed or filtered, the result would be toxins accumulating in the body. This would create swelling and also prevent the body from fighting against infection and disease.

Disorders or complications originated in the lymphatic system create serious illness in the body. This is because this…… [Read More]

Skeletal System Purpose and Functions

Calcium is needed in blood clotting, stability and permeability of the membrane, nerve conduction, muscle contraction, cellular secretion, enzyme activity, and cell growth. Magnesium is needed for the metabolism of potassium and calcium and for the mobilization of calcium from bones. Phosphorus plays and important role in the development and maturation of the bone. Its chief role in bone resorption, mineralization and collagen synthesis makes it essential in calcium homeostasis (Michael's).

Diseases and disorders of the skeletal system include leukemia, bursitis, osteoporosis, sprains, fractures, spina bifida, scurvy, arthritis, scoliosis, talipes equinovarus or clubfoot, tendonitis, kyphosis and poliomyelitis (Family Shock 2001). Leukemia is also called cancer of the blood where abnormally large numbers of white blood cells multiply at an uncontrolled manner so that they interfere with the body's production of red blood cells. The cause is still unknown. ursitis is a painful condition, which most commonly affects the hips and…… [Read More]

Endocrine System in the Human

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)

Main Systems of Human Body

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]

Why the Lymphatic System Is Not Present in Certain Organs

network of lymph vessels and lymph nodes in the human body termed the lymphatic system that is an important component of the immune system (Lymph system, 2015). The lymphatic network collects waste materials, fluid, and pathogens such as bacteria and viruses in the body and carries lymph, a clear watery fluid that contains white blood cells called lymphocytes that help fight infections (Lymph system, 2015). To gain some additional insights into its purpose and operation, this paper provides an explanation concerning why the lymphatic system is not found in some parts of the body and describes what areas have no lymph or lymphatic vessels. A summary of the research and important findings concerning these issues are provided in the conclusion.

But argument and criticism carried on across the boundaries of two or more different sets of fundamental assumptions may not intersect sufficiently for discourse to be productive, or even meaningful. Systematic improvement of intellectual performance, justification and criticism of knowledge claims, must proceed from a foundation of known, though not necessarily shared, basic assumptions. Conclusions are inseparable from the assumptions and reasoning on which they depend.

Systems theory and healthcare delivery in the U.S.

According to theorist Ludwig von Bertalanffy, it is essential to view organisms -- both living and man-made -- as functional systems in a holistic sense to understand their true nature. This principle is manifested in the human body and also the organizations which provide healthcare. "A complex adaptive system is a collection of individual agents with freedom to act in ways that are not always totally predictable, and whose actions are interconnected so that one agent's actions changes the context for other agents. Examples include the immune system, a colony of termites, the financial market, and just about any collection of humans (for example, a family, a committee, or a primary healthcare team)" (Plsek & Greenhalgh 2001: 625).

Legal Justice Information Systems Integration

For instance, in the eyes of the courts, an offense's level could be equated to the guideline for the seriousness of a crime. The next aspect of the scorecard was the offender's personal or associative criminal history. Prior offenses dictated a level of conviction frequencies and social offenses. Therefore the personal criminal history of an individual ends up playing a major role in the sentencing guidelines. A person's propensity to repeat offences entails longer sentences. The person that had a history of repeat offenses offered a greater threat and therefore was often thought to be more dangerous to society. but, how does the justice system maintain a culprit's history without an ability to utilize integrated processes?

This is a prime example of where justice information systems integration could have far reaching implications. In regard to sentencing, first time offenders in one community may not have been labeled as serial offenders…… [Read More]

British Parliamentary System of Government with the United States Federal System of Government

The British Parliamentary system of government is one of the oldest political systems in the world that has evolved over a period of centuries. The British model has influenced the system of governments in many countries of the world including the United States. On the other hand, the U.S. system of government is a Federal system that came into existence when the United States (the former American colonies) rebelled against British rule and declared its independence in the latter part of the eighteenth century, followed by the adoption of its own constitution in 1787. Although having some similarities with the British System of government, the U.S. system of government is unique in several aspects, having its own characteristics. In this paper we shall look at some key features of the two systems of government and compare and…… [Read More]

Hacker Culture and Mitigation in the International Systems

The explosion of the internet technology in the contemporary business and IT environments has assisted more than 300 million computer users to be connected through a maze of internet networks. Moreover, the network connectivity has facilitated the speed of communication among businesses and individuals. (Hampton, 2012). Despite the benefits associated with the internet and network technologies, the new technologies have opened the chance for hackers to attack the information systems of business organizations and collect sensitive information worth millions of dollars. Each year, businesses have been a victim of cyber-attacks in the United States. As an increasing number of people and businesses own internet-enabled devices, more businesses have become a victim of cyber-attacks, which has become a critical concern in the business and governmental environments.

American Education System Has Come

Teachers should feel the pressure when their students do not succeed while opponents argue that placing such pressure on teachers just adds to the problem and makes success just that more difficult and unlikely.

Even the most ardent opponents to standardized testing among the teaching profession would likely argue that the demand for accountability is a legitimate one. Every profession needs to establish its credibility among the public and teachers should not be immune from this process, however, what has been lost in the process of trying to make teachers accountable is the value of what can be learned beyond the preparation for the standardized test. There is a necessity and value in establishing accountability but the method of using the standardized test to do so must be questioned.

When the use of standardized testing first came into vogue throughout the U.S. The goal was to establish a procedure for…… [Read More]

Where, each country / region has different on laws and regulations pertaining to the real estate markets. This means that the risks in a number of different markets will depend upon specific market conditions themselves, reflecting these two factors. To protect themselves against these kinds of risks, many investors will often seek to diversify their portfolio. Diversification is: when you are investing a number of different asset classes in real estate, across a variety of countries / regions. The idea is that if a risk occurs in a specific country or region, the other areas that you are diversified in will protect you against the severity of the declines. For…… [Read More]

Ideal Performance Management System

Performance Management and Performance Appraisal eport:

Military

As a member of the U.S. military, my organization's current performance management and performance appraisal system is driven by very unique needs. It is in many ways highly bureaucratic and standardized. This is so that the requirements of the organization vs. The personal and subjective responses of supervisors define the ratings process. It also has specific mechanisms for the mentorship of soldiers advancing through the system. Although there are certain aspects to the Army's performance management approach which are quite specialized and specific, I believe that any organization, including private for-profit enterprises, could learn from its philosophy. Its strong emphasis on mentorship and performance feedback minimize frustration with criticism and the candidate's sense of being unfairly judged. The process is on one hand uniform in terms of the benchmarks to which candidates are held but on the other hand, the coaching and individualized…… [Read More]

Immunocompromised patients usually require isolation in order to prevent them from becoming infected with infections from other patients which is known as protective isolation. For the immunocompromised patients, their immune system is unable to fight the infectious diseases. There are many diseases or conditions that lead to immunodeficiency in patients.

One is AIDS (acquired immunodeficiency syndrome). The pathophysiology of AIDS starts when the person's CD4+ T cell count begins to decrease as the disease kills these cells. This is HIV-induced cell lysis where the virus enters the CD4+ cells where it inserts its genetic information to the cell nucleus thus taking over the cell and replicating itself. The virus then mutates extremely rapidly thus making it more and…… [Read More]

B lymphocytes originated in 1960s and 1970s era through experiments conducted in animal models, clinical evaluation of patients having immune system diseases, and the nascent technology of cell surface molecule characterization. In fact, the origin of B. And T. lymphocytes took place simultaneously. The differentiation of the haematopoietic stem cells gives birth to the formation of common lymphoid progenitors, which actually generate B. lymphocytes. They are generated and developed in yolk sac, fetal liver, and the adult liver present in the body (Austyn & Wood, 1994). B lymphocytes are present in areas that come in close contact with foreign substances. They act as defensive mechanism against invading microorganisms, viruses and parasites and play a vital role in humoral immune response. Since these cells originate in the Bone marrow, they…… [Read More]

It can be concluded from the above figure that there was a significant increase in the number of children aging out of foster care system from the year 1998 to 2007. Whereas, this number started declining from the year 2008 and it is still following a declining trend. (McCoy-oth, DeVoogh & Fletcher, 2011)

Immunology Toll Like Receptors

Immunology - Toll-Like receptors

The family of Toll-like eceptors has gained in importance since the discovery that they could be potential regulators and controllers of the immune response system in the human body as they are capable of recognizing the molecular patterns that are associated with pathogens. It was found that Toll-like eceptors are capable of recognizing endogenous ligands, as well as microbial components and those Toll-like receptors are activated by small-molecular-mass synthetic compounds and for these reasons the Toll-like eceptors are significant in that they are potential targets for the development of new therapies for several diseases. (Toll-like receptors as potential therapeutic targets for multiple diseases)

The blood with the IgG must be effectively removed from the body, or reduced to levels that will not allow the cells to be a danger to the infant. If caught early enough, plasma transfers for the mother can result in enough of a reduction of IgG levels to forestall the effects to the fetus.

8)

Autoimmune diseases occur when, for a variety of reasons, the body responds to its own cells as though they were dangerous foreign cells. In this way they are similar to an allergic response; an unrecognized but harmless entity is viciously attacked by the body in an attempt to destroy the perceived intruder. This is annoying (and possibly deadly) when it comes to allergies, and far more so when the body essentially becomes allergic to itself.

Though the reasons behind the onset of Type I diabetes are still not fully understood, the disease occurs when…… [Read More]

HIV Human Immunodeficiency Virus HIV Is a

HIV

Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system causing the individual to be at risk for opportunity infections, or infections that come about because the immune system is weak. It is a slow progressive disease that is present throughout the body. Humans can get infected with HIV through contact with tissues, such as vaginal, anal area, mouth, eyes, or a break in the skin, such as a wound. It is diagnosed with blood tests and treated with a combination of drug therapies. There has been no cure found for HIV, so the person ends up dying from the virus in the long run.

The most common way HIV is spread is through sexual contact, needle sharing, and transmission from an infected mother to a baby through pregnancy, labor, or breastfeeding. It is spread by body secretions of an infected person to tissues of another person.…… [Read More]

Stress Response Associated With Cardiac Bypass Surgery and Anesthesia Concerns

Cardiac Stress Response: The Use of Anesthetic Technique to Promote Positive Outcome; Analyzing the Pros and Cons of Technique

Cardiac surgery by nature elicits a powerful stress response resulting from activation of stress hormones including epinephrine, norpinephine and cortisol hormones among others. Surgical trauma and blood loss may contribute to this stress response. Some surgeons have suggested that cardio pulmonary bypass surgery in and of itself activates an inflammatory response that results in a stress reaction.

The role of the anesthesiologist in cardiac surgery is to as much extent as possible, to reduce the stress response that results form cardiac surgery. Stress response can be mitigated by a variety of anesthetic technique, including use of opioids and epidural anesthesia. These ideas are explored in greater detail below.

Autoimmune Disorders Maladaptive Responses to

"Inflammatory Bowel Diseases (IBD) is a broad term that describes conditions with chronic or recurring immune response and inflammation of the gastrointestinal tract. The two most common inflammatory bowel diseases are ulcerative colitis and Crohn's disease" (IBD, 2013, CDC). Ulcerative colitis affects the large colon; Crohn's usually affects the small colon and the beginning portion of the large colon. egardless in both manifestations of IBD, the body attacks the cells of the intestine, mistaking 'good' things like food and bacteria for dangerous invaders and thus causing chronic inflammation.

The effects of IBD can be extremely severe because of the nausea, vomiting, diarrhea and subsequent weight loss and malnutrition that they cause. Crohn's is particularly dangerous because it can cause intestinal blockage from severe swelling and scaring. Ulcers can cause fistulas which become infected. Unlike lupus, both forms of IBD can be treated with surgery as well as various anti-inflammatory drugs.…… [Read More]

Psychological and Physiological Effects of Exercise on the Mind and the Body

Exercise has been described as the best medicine for depression. It can help a person get through rough times. Physical exercise is very important for a person's mental and physical health. Exercise helps in pumping more blood through the veins. This results in the increase in size of the arteries and it prevents fats from clogging the arteries. It also prevents blood clots. A person who exercises regularly is protected from a variety of diseases and it helps in curbing cholesterol. Exercise benefits a human body as it lowers blood pressure and conditions the lungs. Exercise has its various advantages. It successfully counters stress, depression and anxiety. It has been named as the best fighting force for all these problems. Exercise is also instrumental in improving a person's nervous, cardiovascular and immune system. It also increases our metabolism, digestion and stimulation.

Due to Run Off From

The inquiry cited above makes use of the functions of analysis, synthesis and evaluation. Analysis is the act of reviewing and comparing data. In the inquiry of the herbicides, the analysis occurs with the review of prior evaluations and inquires. This analysis of studies regarding the effect of atrazine allowed the inquiry to come up with its hypothesis and thus direct the actual experiment. Without an analysis of the original, existing data the concept of comparing use of atrazine, isoxaflutale and a mix of both would not have been thought of.

The concept of synthesis refers to the integration of two or more existing elements in order to create something new. In the inquiry, there are numerous levels of synthesis. First and foremost is the agricultural practice of combining atrazine with isoxaflutale as a method of creating a new, supposedly less toxic herbicide that would comply with the regulations issued…… [Read More]

Antibodies List the Five Different Kinds of

Antibodies

List the five different kinds of antibodies and describe each of their functions.

An antibody is a protein used by the immune system to identify and neutralize invaders, such as bacteria and viruses. The term immunogloben is often used interchangeably with the term antibody. The first primary function of antibodies is to bind antigens. The second primary function is to combine with immunoglobulin receptors. The five classes of antibodies are IgG, IgA, IgM, IgD, and IgE.

IgG is the most common antibody in the human body. It is the only antibody which can pass through the placenta, so this is what provides fetuses with protection before they develop their own immune systems. IgG can bind to a wide range of pathogens.

IgA is found in the stomach, intestines, breast milk, tears, and saliva. IgA fights pathogens which contact the surface of the body, and pathogens which are swallowed or…… [Read More]

Explain how HIV infects CD4+ cells?

The HIV (human immunodeficiency virus) is the virus which belongs to a group of viruses known as the retroviruses. HIV causes in AIDS (acquired immunodeficiency syndrome) by infecting the cells of the human and uses up all the energy inside the cells which is required for the growth and development of human cells. AIDS is a fatal disease in which the immunity system of the human body is destroyed due to which the body becomes vulnerable to various infections and also the weakness of the body's immune system also allows other diseases to attack the body. Once a person is infected with HIV, this virus feeds on the energy present in the cells and multiplies in the white blood cells. White blood cells are the ones which build up the immune system and when they are weakened by the HIV…… [Read More]

Pseudomonas aeruginosa

Epidemiology

The Gram-negative, motile, rod-shaped bacterium Pseudomonas aeruginosa is an opportunistic killer that takes advantage of people suffering from medical problems (Van Delden and Iglewski, 1998).For this reason, P. aeruginosa is one of the most common nosocomial infection that occurs in hospitals. P. aeruginosa is responsible for causing 16% of pneumonia cases, 12% of urinary tract infections, 10% of bloodstream infections, and 8% of surgical infections due to hospital care. Patients who are immune-compromised are also susceptible to P. aeruginosa infections, such as patients undergoing chemotherapy, suffering from HIV / AIDS, recovering in burn units, and suffering from cystic fibrosis. With death rates ranging from 30 to 60% for these patients, P. aeruginosa is considered to be a significant threat to patient health.

Ecology

P. aeruginosa can switch between a free-swimming planktonic form and colonies enclosed within slime-protected biofilms attached to surfaces (Baltch and Smith, 1994,…… [Read More]

Living Things Are Characterized by the Following

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

1-2). Based on previous research that found that Akirin proteins were ubiquitous in flies and humans and strictly nuclear, Tufet sought to determine if the Akirin homologues had a similar function in mice. While the experiment using Akirin-1 failed to produce any meaningful results, the tests using Akirin-2 showed that it acts in tandem with or downstream of NF-B in the regulation of TL- and IL-1-inducible gene expression (Tufet).

This author concludes, "This study has identified a previously unknown nuclear factor that, together with or downstream of NF-B, can regulate innate immune responses. Further studies will be needed to determine precisely how Akirin proteins control gene expression" (Tufet, p. 3). The strengths of this summary were two-fold: (a) the author provides an understandable overview and background of the investigation and its rationale, and (b) the timeliness of the study results makes it a valuable addition to the existing body of…… [Read More]

Treatment to Patients the Main Objective of

Treatment to Patients

The main objective of providing treatment to patients is to relieve symptoms along with decreasing the progression of the disease as well as the mortality or morbidity. However, in some cases, this objective is not fully achieved, especially in the case of the patients who are admitted to the ICU with some serious and almost always a terminal stage of the disease. For example, when old patients are admitted in the ICU, their immunity is extremely low and this is the perfect time for the opportunistic infections to make matters worse for these patients. There are many infections that are specifically associated with patients admitted in the hospitals. Pseudomonas Aurigeonosa is a micro-organism that is well documented to cause bacterial pneumonia and bacteremia in the patients who are terminally ill and are receiving treatment in the hospital setting. Since most of the patients in the ICU are…… [Read More]

Progress of Vaccine Development Particularly the Challenges

progress of vaccine development, particularly the challenges. There is also a discussion of funding and its impact on HIV research.

Ever since HIV / AIDS made the evolutionary jump from chimpanzees to humans, it has infected approximately one percent of the global population; in 2005 it killed almost three million people alone. HIV's continued spread is due to its ability to evade the human immune system and vaccines (Understanding Evolution, 2007).

Even with recent advances in scientists' understanding of HIV origination, development and immunology, there are still major scientific obstacles. Several prototype HIV vaccine candidates have failed so far to protect against HIV infection or to reduce viral loads, that is, the concentration of HIV virus in the blood after infection during clinical studies of effectiveness. Therefore there must be a renewed, well-coordinated commitment to conducting basic discovery research as well as preclinical studies and clinical trials (Barouch, 2008).

Stem Cells Are Non-Specializing Cells

Dimitrios Karussis and Ibrahim Kassis, in the article, "Use of Stem Cells for Treatment of Multiple Sclerosis," conclude,

"In the current review, the various types of stem cells, which were mainly studied in animal models, will be reviewed as a potential therapeutic approach for MS. The main and common mechanisms of action of all stem cells include induction of neuroregeneration and remyelination through the activation of resident stem cells, or production of new CNS cell lineage progenitors, paralleled by local and systemic immunomodulating effects" (Karussis & Kassis, 2007, Conclusion ¶).

The other diseases that are showing promise in treatments resulting from stem cells usage includes: as cancer, diabetes, osteopetrosis, rheumatoid arthritis, Alzheimer's disease, Parkinson's disease, spinal cord injuries, heart disease, immune system disorders, blood disorders; the list goes on (Diseases Treated by Cord lood, 2010).

Conclusion

Stem cells are a valuable weapon in the future treatment of disease and in…… [Read More]

Merkel cell carcinoma is a relatively rare disease in which malignant cells form in the skin, usually in individuals who have a weak immune system or extensive exposure to the sun. Merkel cells are found in the top (epidermis) layer of the skin, close to the nerve endings that house responders to touch. Merkel cell carcinoma is also known as neuroendocrine carcinoma of the skin, sometimes as trabecular cancer. It forms when the Merkel cells grow rapidly and out of control, usually starting in areas of the skin that have more exposure to the sun (neck, arms, legs, etc.). The cancer tends to grow robustly and metastasize at a relatively early stage. Typically, it spreads to nearby lymph nodes and then…… [Read More]

Diagnosis and Treatment of TB

Tuberculosis

Causative agent

Tuberculosis is an infectious disease of animals and humans. The most common causative agent of the disease is a bacterium a mycobacteria known as Mycobacterium tuberculosis. This bacterium was first discovered by obert Koch in 1882. The physiology of this bacterium is aerobic and hence requires very high oxygen levels. This is primarily a pathogen of the mammalian respiratory system which infects the lungs. The most common methods used to diagnose tuberculosis are acid-fast stain, tuberculin skin test and chest radiations. M. tuberculosis requires oxygen in order for it to grow. Due to the presence of mycolic acid, M.tuberculosis has an waxy coating on its surface which is unusual making the cells impervious to Gram staining It can not retain any bacteriological stain as a result of a high lipid content on its wall therefore acid-fast staining or ziehl-Neelsen staining are used. Despite this M.tuberculosis is still…… [Read More]

Global Nutrition According to Who

According to UNCEF, replacement of many nutrients such as protein, potassium, magnesium and zince is essential for recovery from malnutrition (http://www.unicefusa.org/news/news-from-the-field/treating-malnutrition-as.html).The organization mentions ready-to-use therapeutic foods such as F75 and Plumpy'nut. F75 is high in energy, fat, and protein, and provide a large amount of nutrients while Plumpy'nut contains vitamins A, B-complex, C, D, E, and K, and minerals calcium, phosphorus, potassium, magnesium, zinc, copper, iron, iodine, sodium, and selenium.

WHO advises that a diet rich in fruit and vegetables contains immune-system boosting mironutrients that can help those suffering from over nourishment to boost their body's natural defenses against infectious diseases (http://www.wpro.who.int/media_centre/press_releases/pr_20030304.htm)… [Read More]

Gilbert Short or Long-Term in

The following quotation, in which the author discusses how one of her patients was so adept at disassociating from painful situations that her appendix nearly ruptures, exemplifies this argument. "I don't want to die because I can't feel anything. I don't want to end up dead because I can't feel what's going on in my body…" This quotation from Stout's patient Julia indicates how hazardous it can be to gratify oneself for the present moment only to make one's future infinitely worse because of that fact. Julia was so good at disassociation from pain that she was not aware of when there was a reason for the pain and needed to help herself. Similarly, GenMe has been so pacified by the self-esteem movement that in the future, they will lack many of the essential attributes to be able to conduct happy, productive lives. This is largely due to the fact…… [Read More]

importance of vitamin c in body

Vitamin C is not endogenously created in the human body, which is why it is essential that human beings receive enough Vitamin C in their diet. Diseases like scurvy can result from inadequate intake of Vitamin C, also known as L-ascorbic acid. Vitamin C performs a plethora of functions in the human body. It is an antioxidant, it is involved in protein metabolism, and is "required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters," (National Institutes of Health, 2016). Because of the role of collagen in wound healing, it can be said that Vitamin C facilitates wound healing (NIH, 2016). Because of its antioxidant functions, Vitamin C is also critical for optimal immune system functioning (NIH, 2016). Vitamin C also improves the absorption of plant-based iron, or nonheme iron (NIH, 2016). Vitamin C is water soluble and is excreted in the urine.

Absorption rates are optimal at moderate levels…… [Read More]

Tumor Suppression Protein 53 and Effects on Cellular Function and Aging

The concept of aging has many intrinsic and extrinsic factors that act as markers on an individual organism. Ignoring mortality associated with external environmental factors, very few organisms can be said to have cellular immortality with no decrease in cellular function or repeat division in normal diploid cells. Cellular senescence is a normal process that halts cellular division after a set of cycles of replication. Senescent cells can remain completely functional but lose the programmed process of replication. The normal pathway for senescent cells is either aging with metabolic pathways continuing for the cell or programmed cell death which is known as apoptosis that occurs when cellular function changes, a specific lifetime is reached for the cell or the cell is damaged. The multicellular cnidarians known as a Hydra has been shown to have a…… [Read More]

Patients Making Bad Decisions

Medical ethics and rules like the Hippocratic oath are fairly clear-cut when applying them to real-world solutions and situations. However, there are some situations where the "right answer" can be elusive and people will sometimes go against their own self-interest. Such seems to be the case with Mr. Simpson. He has weak lungs and his doctors and family morbidly fear that if/when he gets the flu again, it will literally kill him. However, even with this being the case, Mr. Simpson refuses to get the flu show under the auspices that he could end up getting the flu as a direct result of the shot despite assurances that this will not happen. Of course, this can absolutely happen in real life but that argument is not a factor in this case study as it is assumed he cannot possibly contract the virus. While Mr. Simpson is obviously not making the…… [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).

Adrenal Gland Keeping the Body

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]

Prevention and Treatment

HIV / AIDS is one of the most prevalent and devastating diseases in the world today. It has already killed millions throughout the world, especially in developing countries like Africa. I chose this topic due to the importance of HIV for world heath issues and because of the larger social issues that this virus has for many countries. The statistics over the last decades are evidence of the growth and devastating effect of this virus. The total number of recorded deaths due to HIV / AIDS, between 1981 and 2003, was a staggering 20-million. The number of children in Sub-Saharan Africa who were orphaned by the end of 2003 was an estimated 12-million. Later figures indicate that the situation in Africa is not improving, with these figures increasing in 2004, especially among women in Africa. "y December 2004 women accounted for 47% of all people…… [Read More]

Respiratory Syncytial Virus RSV Is

It has also been suggested that low-level viral replication associated with SV may be a driver in chronic inflammation in some sufferers of chronic lung disease, although this is so far uncertain (Openshaw, 2005). It is estimated that infants who develop a wheeze as a result of SV contraction develop a recurring wheeze in around two thirds of all cases. It is also estimated that around half of these children will develop some form of asthma (Lehtinen et al., 2007). It is unclear why there are some who experience delayed onset of SV, although both immune 'imprinting' and viral persistence have been implicated (Openshaw and Tregoning, 2005).

Diagnosis

The condition is diagnosed through rapid antigen-detection tests. It is difficult to diagnose SV in adults as the tests are insensitive in persons other than children, and practitioners rarely request tests for SV in adults. This means that it is difficult to…… [Read More]

Multiple Sclerosis

Multiple Sclerosis
Multiple sclerosis or MS refers to an autoimmune, chronic condition which impacts physical movement, function and sensation. The problem sets in following neuron insulation destruction (i.e., myelin sheath destruction) within an individual’s central nervous system (CNS) (Cengage Learning, 2013). Symptoms of the disorder start showing up at early adulthood, greatly impacting patients’ domestic, social, and professional lives. As the absence of myelin retards action potential conduct, the disorder is manifested as performance impairment, having a potential destructive influence on patient behavior. MS often entails a relatively progressive onset of behavioral deficiencies and neurological symptoms (Hoang & Shepherd, 2010).
Multiple Sclerosis and Nervous System

Additionally, atrophy and white matter lesions are known to play a significant part in cognitive dysfunction among individuals diagnosed with…… [Read More]

Vitamin D Is a Group of Fat-Soluble

Vitamin D is a group of fat-soluble molecules known as secosteroids. Vitamin D itself is a fat-soluble vitamin that is not available in many foods. However, photochemically, it is produced when ultraviolet rays from sunlight strike the skin and trigger Vitamin D synthesis. Vitamin D externally, though, is biologically inert in the human body, and "must undergo two hydroxylations in the body. The first occurs in the liver and converts Vitamin D to 25-hydroxyvitamin D The second occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin d (VanDen Berg 1997, S76). Although called a vitamin, Vitamin D is not actually an essential dietary vitamin because it can be synthesized in more than adequate amounts from sunlight. Typically, an organic chemical, or group of chemicals, is known as a vitamin when it must be obtained through diet or other means, and cannot be synthesized through bodily processes.

Health Factors Influencing Support of

It is a well acknowledged truth that memory related diseases like Alzheimer's are common in older people rather than younger ones. Memory tends to becomes less competent with age. It might take longer to learn new things or remember familiar words or names. Many measures can be adopted to reduce the increasing adverse effects of memory like eating a healthy diet, including physical exercise as a part of daily routine and by being social. Despite of adopting these measures to reduce the effects of growing age on health, these problems cannot be eradicated completely. Young people are more energetic and are less viable to diseases because of the strength of their immune system. They have a stronger defense system against diseases because of the age. There is a strong relationship between age and support of health. Aging is inevitable. It is tend to occur but applying few important measures cannot…… [Read More]
