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 either suppressing or eliminating autoreactive immune cells. Some ...

For my student practical skills development training, I had the opportunity to be placed as a trainee in the Immunology department of a Women’s and Children’s Hospital.

A career in laboratory medicine requires a lot practical skills and one has to be conversant with many laboratory procedures involved.
The Women’s and Children’s Hospital is one of its kind. It is a care facility that centers on family needs, and it is specifically dedicated to offering ...

Introduction

Allergy is an immune system disorder. Allergy or allergic reaction is a hypersensitivity to otherwise innocuous substances present in the environment. The allergic reaction is usually a rapid response; however, the sensitivity to certain allergens can be acquired over a period. It was previously called the type one hypersensitivity. It is characterized by an over activation of leucocytes, called the mast cells and the basophils following activation of immunoglobulin E (IgE) (Frigas, Gleich 1986). This activation of the basophiles and mast cells triggers an inflammatory response.

Pathophysiology of the allergic response

The type 1 hypersensitivity reaction is initiated when an allergen is introduced to the atopic individual, ...

Cortisol is a steroid hormone synthesized in adrenal glands with a myriad of functions mainly in the endocrine and immune systems, and produced during stress circumstances. Under normal conditions, stimuli such as a pathogen release immune proteins called interleukins, which further activate T-lymphocyte cells. T-cells multiply to amplify the immune response and ultimately attack the pathogen (Abbas, 2014). Other immune responses are simultaneously activated, e.g. the complement system. The complement system exerts its functions through three pathways: classical, alternative or lectin pathways. The main activators of the classical pathway are antigen-antibody complexes, which trigger a series of events mainly mediated by complement proteins ...

What tangible and intangible resources will be needed to implement your project? Some of the key tangible resources required for the successful implementation of educational programs on food allergies and asthma would include furniture, equipment (projector/monitor/laptops/computers), cash (finances), inventory, and space (classrooms/halls) (Järvinen, & Celestin 2014). Most of these resources may already be present. However, cash (finances) and inventory required may have to be raised from external funding. Intangible assets may include the 6-month contract, manuscript, medical records, computer software, and blueprint of the entire project (Dearholt & Dang 2012).
What improved outcomes do you anticipate will occur that could ...

It has been estimated that 26 million Americans suffer from asthma symptoms, attributing to the majority of work- and school-related absences across the country (ACAAI, 2014). The American College of Allergy, Asthma and Immunology defines asthma as, “a chronic lung disease that inflames and narrows the airways in the lungs” (ACAAI, 20014). This causes difficulty in breathing, termed asthma, and may lead to life-threatening consequences. The lungs allow air in and out by a network of airways, called ...

GERD: Introduction

“Gastroesophageal reflux disease (GERD) is a syndrome wherein the stomach’s contents of those in the small intestine constantly move up into the esophagus. The rearwards motion of the contents is called a “reflux.” This condition results in the person being subjected to episodes of heartburn, a stinging sensation felt under the sternum part of the chest, is the initial symptom of heartburn; this is traditionally felt after the person has a heavy meal, or lies down or lifts a heavy object immediately after eating. If a person is consistently experiencing bouts of reflux and extreme heartburn, then ...

The patient is a 9-year-old boy, who visited the general practitioner with his 37-year-old mother. The general practitioner reviewed the patient’s medical history and conducted an interview with the patient’s mother to learn more about the boy’s family history, as well as the history of the boy’s chronic cough. The mother reported having seasonal allergies, especially during springtime when plants release their pollen. However, the boy had no known allergies or respiratory problems according to his mother and his medical history.
The physical examination included the assessment of the patient’s vital signs, nasal canals, ...

Major Achievements in Biology

Researchers and scientists are always intrigued by biological processes and activities, and strive to utilize them for benefit of mankind. Antibiotics, monoclonal antibodies, vaccines and several therapeutic agents, high yielding as well as disease tolerant plants and animals are all results of extensive research in the fields of cell and molecular biology, immunology, biotechnology and genetic engineering. Treatment to several diseases, even genetic disorders are available today only due to breakthrough discoveries in biology. Three such important discoveries are revelation of structure of ribosomes through X-ray crystallography, identification of tumor specific antigens (TSA) expressed on the surface of cancer ...

The administration of proper medication is essential to the treatment of a health complication. As such, medical practitioners need to enforce proper measures in the issuance of medicine to enhance the betterment of patients (Bojesen et al. 375). The purpose of this study is to evaluate the value of medicines through the utilization of a case study. This study will be in line with the code of conduct for Oncologists since the medical practitioner in this scenario deals with cancer patients. Since the maintenance of confidentiality is essential to the success of the medical practice, the practitioners’ and patient’ ...

The Definition and Symptoms of Asthma

Asthma is a common medical condition which is chronic and involves the airway. It is a complex disease which is symptomatized by repeated instances of inflammation resulting in varying degrees of airflow blockage and a hyperactive bronchial response. The way the disease manifests clinically, the level of severity, and the treatment efficacy is determined by the interaction of these features.
The symptoms of asthma are usually preceded by specific triggering events or stressors such as physical exertion, pollutants, or weather changes. Asthmatic episodes may also be seasonal, especially for children who have seasonal allergies (Ege, Mayer, Normand, Genuneit, Cookson, Braun-Fahrländer, & ...

Introduction

Genes are the smallest functional units present in the human body, which controls the development and formation of the organism. These genes are present on the chromosomes as pair and are expressed when the body needs a certain protein or compound. However, at times, one or both the genes may be faulty due to mutations. This impaired gene causes the formation of a Genetic disorder. These genetic diseases were studied with the tools of biotechnology and thus developed the Gene Therapy technique (Sheridan 121).
Gene therapy is a tool that uses biotechnological techniques to prevent diseases caused by defective genes. It ...

Introduction

The fight or flight response is one of the body’s autonomic defense mechanisms. This innate defense mechanism gets triggered whenever a person encounters a harmful entity or event, or basically anything that one may perceive as a threat to his survival. In such cases, the body’s hyper-arousal state which is characterized by dramatic changes not just in one but across all organ systems. The fight or flight response actually started as a simple theory by Dr. Walter Cannon. Dr. Cannon explained that any animal is subject to a reaction called fight or flight response which is characterized by a general and fast-acting discharge ...

With more than 25 percent of the world’s population reportedly suffering from allergic-reaction related conditions, allergy is increasingly becoming one of the world’s widespread conditions. Oft marked with a characteristic features such as itching, sneezing and vasodilatation, an allergy, according to Ahmed (2011), is an overreaction of an individual’s immune system to a substance (allergen) which does not usually cause any reaction to other people. Such an overreaction occurs when the body recognizes a substance as foreign thereby inducing an immune response marked with the production of antibodies.

Mechanism of an Allergic Reaction

An allergic response, as affirmed by Ahmed (2011), can conveniently be ...
