Essays on Immune System

Ultraviolet light (UV) is a largely invisible variant of light which has intense electromagnetic energy and whose wavelength ranges from 0.1 μm to 0.4 μm. Normal visible light varies from 0.4 μm to 0.7 μm. There are, however, levels at which UV light can be visible to some organisms like birds and insects. It is different from visible light because it is of its high concentration; can result in chemical reactions and can harm human beings.
UV light is majorly derived from the sun. In addition there are other particular sources which can be utilized for production of these ...

Vaccinations

Part 1: Vaccinations are mandatory for most babies and school-aged children as they build the body’s immune response. What are some pros and cons of vaccines?
Despite some reported risks of vaccines, for many medical professionals, these risks outweigh the benefits children get from them. Vaccines are believed to be responsible for the decline and prevention of infectious childhood diseases. However, vaccines do not guarantee 100% protection from illnesses. If a child contracts (who has been vaccinated) a particular disease, he or she experiences milder symptoms and complications (“Pro & Con Arguments,”2014), making it a lot easier to ...

Indoor Air Pollution: Diagnosing the Causatives and Effects

Indoor air pollution is the presence of physical, chemical and biological contaminants in the indoor air that are never present in the quality and environmental friendly atmosphere. These contaminants can be particulates, gases, moulds or radon which is the main causes of the pollution. The human immune system protects the entire body against the negative effects of these contaminants. The contaminants impair the immune system after prolonged exposure. A survey published on the metropolitan area of Toronto revealed that almost 2 percents of the annual deaths were caused by indoor air pollution (Tom, 1996). In this essay, we have ...

Immunology Disorders

The immune system is responsible for protecting the body from various parasites, bacteria, virus etc. that try to destabilize the homeostasis. Naturally, the immune system is considered one of the most important mechanisms that help us recuperate from diseases. When the immune system malfunctions and starts destroying self-cells, it leads to certain disorders. In other circumstances, the immune system may be suppressed and fail to kill disease causing cells. Here we will discuss a few disorders of the immune system.

HYPERSENSITIVITY TYPE I

Allergy or hypersensitivity type I is also known as allergic reaction or intolerance, in this scenario the immune system ...

The immune system has an immune arsenal that help in the combat of infections including the challenging viral infections (Iannello 2006). Upon infection by a virus, the host invariably reacts by activating its line of defenses. These immune defenses can fall into two main groups: the innate immune system (first line of defense) and adaptive immune response. The innate immune system is non-specific in nature, but the adaptive immune system is acquired following previous infections or vaccinations (Iannello 2006). However, viruses continue to undergo an evolution and have engineered strategies that evade the hosts’ immune antiviral responses. This paper ...

‘Stem cells’ is one of the widely discussed topics in recent years. Scientific progress led to the understanding the mechanism of stem cells and their use in therapeutic applications, which involve the treatment of cancer, diseases related to heart, brain and many others . Stem cells are a distinct type of cells, which are capable of regenerating themselves through the process of cell division. Under experimental conditions, stem cells have the ability to transform into tissue-specific or organ-specific cells. Since stem cells are unspecialized cells, they are capable of producing specialized cells through the process of differentiation . While embryonic stem ...

What is septic shock? Septic shock is the situation in which the blood pressure dangerously and in result of wide-body infection is reduced. Therefore, in result of the presence of the bacteria in the blood, or bacteremia septic shock may happen. When the toxins produced by bacteria is released into the blood the immune system responds, which leads to a blood pressure reduction, in order to prevent the delivery of the toxins to the vital organs. Generally, in result of septic shock multiple organ failure may happen, such as respiratory failure that may lead to rapid death.

Pathophysiology of Septic Shock

Differentiation of white blood cells by light microscopy

Most mammals have blood consisting of three types of blood cells, Red blood cells (Erythrocytes), White blood cells (Leukocytes) and Platelets (Thrombocyte). These are collectively termed as hematocyte, which simply means blood cell.
These cells constitute to around 40% to 45% of the blood volume. The remaining consist of Plasma, which is referred to the liquid part of blood. The total volume of blood can be determined by centrifugation or flow cytometry. The 45% of blood component (blood cells) is termed as hematocrit. Another important component of blood is hemoglobin, which gives blood its red color. It is the ...

Benefits of Lymph Drainage Massage

The lymphatic system plays the vital role of defending the body against infection and disease. It can be viewed as the second circulatory system of the body and comprises of the lymph nodes, the lymphatic vessels, the lymph fluid and the lymphocytes. Other parts which form the lymph system include the spleen, adenoids and the tonsils. Since the lymphatic system helps in flushing toxins out of the body, one of the best ways to ensure it functions well is through lymphatic drainage massage (Romano, 2013). The function of this massage is to drain excess fluid from the tissues. Lymphatic ...

It is prudent to begin this discussion by pointing out that there is no definite definition for stress, either as a condition or a word. Therefore, its meaning depends on the context of use. Accordingly, this discussion focuses on stress as a situation that disturbs the equilibrium between a being and its environment; the feeling a being has that demands surpass its resources. This condition no doubt precipitates change in the body’s hormones serum level, as the body tries to respond or protect itself from the stressful stimuli. The most common response is the increase in the levels ...

The human immune system is a proverbial double-edge sword. On one had humans depend on the immune system, and on the other hand there are diseases as a result of its improper function. These diseases due to its disorder in its function can range from immunodeficiency states to hypersensitivity . Put in simple terms, the disorders range from doing too little to an overreaction of the system. There disorders will be considered under the following heading: immune mechanism of tissue injury, autoimmune diseases, and immunodeficiency diseases. Before we go into the details of the diseases, we would like to describe ...

Vaccination is the application of antigenic material, also known as a vaccine, in order to trigger the immune system of a person to create adaptive immunity to an infective agent. Vaccines can preclude or improve morbidity from disease. The vaccination’s efficiency has been broadly analyzed and confirmed. For instance, the HPV vaccine, the influenza vaccine, as well as the chicken pox vaccine (Fiore, Bridges, & Cox, 2009; Chang, Rinas, Schmitt, & Smith, 2009; Liesegang, 2009). Vaccination is regarded as the most effectual way of preventing communicable disease. Widespread immunity on account of vaccination is mainly accountable for the global obliteration ...

These foods have a high nutritional value than others. They are the indigenous food rather than the manufactured ones. The list of the super foods includes salmon, sweet potatoes, avocados, pumpkin seed and blueberries. Super foods have various nutritional disadvantages these include, they may be high on calorie, may not be part of human optimal diet and their availability is seasonal and affected by agricultural waves. In addition, they are economically unviable because they take too long to produce.
Super foods have many advantages to the human body. Their nutrient composition helps the immune system, some can treat diseases, ...

Multiple sclerosis is an autoimmune disease that is hard to treat because of nature in which the body fails to identify itself and starts to destroy itself. The immune system of a MS patient initiates the destruction of the myelin layer around the nerves of the spinal cord, brain and nerves. The breakthrough in the first trial treatment to reset the immune system of MS patients was successful with the research therapy capable of reducing the immune systems reactivity to myelin by up to 75%. When the insulation of the nerves is destroyed, electrical signals transmission is negatively impacted ...

In clinical transplantation, an observed complication is that previous red blood cell (RBC) transfusions may reduce the risk of solid organ transplant rejection but increase the risk of bone marrow transplant (BMT) graft failure (Storb and Weiden, 1981). This statement is seemingly a contradiction. It is difficult to understand how RBC transfusions can both reduce the risk of solid organ transplant rejection and increase the risk of BMT rejection.
But this contradiction can be resolved by understanding three considerations. First, the immune system is extremely complex and attempts to control its effects routinely have both positive and negative effects ( ...

Whereas individuals can respond differently to the same type of stress, if stressed too frequently, the body may suffer harmful effects given that stress is the body's response to challenging situations and circumstances. In biological terms, stress refers to responses by organisms to stressors that could be environmental stimuli or conditions (Heidenreich, 2009). It is usually a way in which individual’s bodies respond to challenges by means of the activation of the sympathetic nervous systems. The resultant effects of the responses to stress could either be a flight response or a fight response. Stressful conditions are typically conditions ...

A pesticide is a contraction that is used to describe various agents, which are categorized based on their ability to kill living beings. These include herbicides, insecticides, as well as fungicides. Even though the utilization of pesticides has duplicated each ten years from 1945, pest destruction to crops is more widespread now than it used to be. Several pests are now resistant to pesticide because of the omnipresent pesticides’ presence in the environment. Residues of chlorinated pesticide are there in the soil, air, and water, with a co-occurrence presence in human beings. Carbamate as well as Organophosphate pesticides, the ...

Immunoglobulins (Ig) are also known as antibodies and they have molecular weights between 160000 and 970000 (Guyton, 2006, p. 443). They are key components of the vertebrate immune system and are a part of the humoral immune system, forming the base of the B-Cell. Igs function in cell-cell recognition as well as structural organization and regulation of musucle (Harpaz, Chothia, 2004). All Igs are made up of a light and a heavy polypeptide chain, usually two of each, but they may contain many more (Guyton, 2006, p. 443). They contain discrete domains of approximately 100 amino acids that are ...

In the 21st century, many people have opted to work out on a daily basis. As a matter of fact, this is caused by the eating habits of individuals in the world, and the food that people take in.

Helicobacter pylori, which was formerly known as Campylobacter pyloridis, is a microaerophilic, Gram-negative bacterium present in the stomach. In 1982, Robin Warren and Barry Marshall discovered that it was found in persons who were suffering from chronic gastric ulcers and gastritis, diseases that were not formerly thought to have been caused by microbes. It is also associated with the development of duodenal ulcers and stomach cancer. Nevertheless, more than 80 percent of persons infected with the bacterium show no symptoms, and it has been contended that it may have a crucial role in the natural ecology of the stomach ( ...

1.0 Background of Immune Tolerance

The immune system is the natural defense that combats disease causing agents in the body[ CITATION Gre02 \l 1033 ] through an intricate and coordinated interactions of many classes of proteins and cells[ CITATION Len00 \l 1033 ].The immune system has a potential to destroy the body cells but in all vertebrates the system is capable of distinguishing “self” from “non-self” molecules. That way the immune system eliminates pathogens and molecules that are a threat to the integrity of the organism without “self-destructing”[ CITATION Len00 \l 1033 ]. The human body has several mechanisms of ...

Abstract

Organ transplantation is an important life-saving procedure for those people, who have some problems in their organs. However, the problem of organ transplant rejection is an important issue in this case. In this problem, patient’s immune system starts rejecting the organ as a foreign body. This problem of rejection of the organ can be acute or become chronic. Several diagnostic procedures have also been developed to reduce the problem of rejection of an organ. Scientists have done a lot of research in this regard. Acute rejection needs immediate care. In order to reduce the problem, specialists will check ...

Schizophrenia:Innovative Research Views on Onset and Treatments
The term “schizophrenia” was coined by Swiss psychiatrist Eugen Bleuler to describe a splitting of psychic functions (Crespi, Sted & Elliot 2010, p. 1736). Schizophrenia is an extremely serious and devastating illness affecting 1% of the American population, causing symptoms that disrupt thought patterns, behavior, and emotions of individuals (Richard & Brahm 2012, p. 757; “Schizophrenia: What” 2012, p. 1). While some sources refer to schizophrenia as a “mental illness,” others refer to it as a “brain disorder” (“Schizophrenia: What” 2012, p. 1; “Schizophrenia” n.d.). Indeed, schizophrenia is a difficult disorder to characterize because ...

Sepsis is a clinical condition that evokes an inflammatory response of the host immune system in response to clinically-suspected infections. It usually occurs in an individual with a weak immune system such as a post-surgery patient, organ transplant patient, cancer patients or an AIDS patient. It spreads throughout the body via the bloodstream. There are several degrees of sepsis such as severe sepsis, septic shock and refractory septic shock (Morrell, Micek & Kollef, 2009) that together make up the systemic inflammatory response syndrome (SIRS) (Mayr, Yende & Angus, 2014). Sepsis and septic shock are some of the leading causes of death ...

Abstract

Stress is a dynamic and interactional process involving intricate body systems with formulations and operationalisation of the components at different levels(1).There is growing evidence that there is a positive correlation between emotional stress and oral health. As will be demonstrated from the literature reviewed in this paper emotional stress can be implicated in oral problems such as ulcerative conditions, inflammatory conditions, dental decay, TMD, RAS and others that continue to be linked to stress. Stress has also been found to aggravate some oral conditions such as oral lichen planus. In some of these conditions the precise mechanisms by which stress causes or aggravates them is not clear though definite association has been demonstrated.

Do people who take vitamins recover faster from the flu and produce a more significant immune response?

Flu, also commonly known as influenza or Grippe, is a virus disease that attacks by infecting the respiratory system, nervous or gastrointestinal system (stomach flu). Rarely fatal, it often opens the door to Pneumonia, Eye and Ear infections and Brian inflammation that do threaten life.  Common colds are usually confused with Influenza, in view of both these ailments attacking the upper respiratory system and showing similar symptoms. In fact they are both caused by different viruses. The worst catastrophe was a devastating world-wide epidemic (pandemic) of Influenza stuck during the summer-winter of 1918 taking the total death toll to about 10 million which included a half-million in the United States of America alone. Actually Influenza virus is around, most of the time harbored by many human beings. They indeed fall ill when their resistance is lowered. Epidemics begin when circumstances to the spread of Flu virus are favorable. There are 3 types of Flu virus.  They are A, B and C.  A type of flu is the most severe and sometimes fatal among these, usually affects the adults. Individuals that are healthy, seldom need diagnosis by a physician, unless of course, he has been haunted by the Flu for over few weeks or the disease itself is very severe in attack.

Peanut allergies have become widespread with more and more schoolchildren diagnosed with this life-threatening allergy condition. As the body considers peanuts as a harmful matter, the body's immune system tries to ward off the infection and "overreacts and releases chemicals, including histamine, into [the] blood" (WebMD, 2011). The exact reasons for developing allergy on peanuts are unknown, but this is considered as one of the most severe types of allergies. In the United States, an estimated 1.5 million people have peanut allergy, including the adults. The numbers are increasing and affect not only First World countries, but developing countries ...

Arguably, HIV/AIDS is one of the global issues that affect all people regardless race, culture or nationality.

AIDS is a disease that is caused by a virus called HIV. The virus lowers the body’s immune system, thus making it susceptible to opportunistic diseases. In essence, the disease has no cure. However, if Aids is diagnosed in its early stages, it can be dealt with, and one can live for an extended period (Aretha, pg. 90).

Immediately the virus enters the body; it alters the body immune system. The following symptoms are experienced; Coughing and breathing difficulties, Fever, Persistent headache and stiff neck, Loss of vision, Weight loss and extreme fatigue which may result as ...

Abstract

This paper describes and discusses the various types of human stem cells, including those in early-stage embryos (the blastocyst) and those present in adult tissue, explaining the practical uses of the various types in the medical field, where stem cells can be used to repair damaged tissue and organs. Although the adult stem cell types offer fewer possibilities for medical applications than the embryonic type, their use is less ethically controversial because it does not require destruction of a living albeit very early stage embryo. Research into stem cell applications is finding improved techniques. These include the treatment of ...

There are two major types of immunity. Innate immunity and the acquired immunity. The type of immunity people gets when they are previously affected by a plaque is usually termed the acquired immunity. This kind of immunity is what stimulate some of the T and B cells to become a memory cell. These groups of memory cells will store the information on how to terminate the plaque when the next time it occurs. The concept map described the components of innate and adaptive immunity. Both have the humoral and cell mediated immunity. The cell mediated immunity described the cellular ...

Abstract

Researchers have been faced with difficult moments in the past in their attempt to find a cure for HIV/AIDS. The trend that the virus takes in the human body is complicated since it stiches itself with the DNA of the host cells hence becoming part of the person. The way to eliminate or remove it from the human body without altering or killing the patient is very complex and it has not been achieved yet. However, some experiments and treatments that involve the use of therapy and stem cells transplantation have proved to be the way forward towards the ...

Asthma is a chronic inflammatory disorder that causes shortness of breath, a feeling of tightness in the chest, and persistent cough. There are two primary types of asthma: intrinsic and extrinsic. Intrinsic asthma comes about through non-allergic means: cigarette smoke, stress, cold air, cleaning agents – basically anything that does not involve an allergen. Extrinsic asthma, on the other hand, comes about through an allergen such as dander, pollen or others. It leads to a constriction of the airway during an attack, leaving the victim out of breath, unable to take in more air, and with a tight feeling in ...
