In Daniel Gilbert’s essay‚ “Immune to Reality‚” he explores how each person’s psychological immune system plays a major role in allowing him or her to cope with traumatic situations that come up in daily life. The psychological immune system is the mind’s cognitive mechanisms that work subconsciously to make the existing state of affairs more bearable. It does this by allowing the brain to make excuses for negative events‚ which‚ in turn‚ help the troubled individual feel better. Gilbert’s conclusions

Immune-Compromised Host: What Can I Do to Fight Pneumonia? Pneumonia is an infection causing inflammation of the air sacs in one or both lungs. The air sacs may be filled with pus or fluid resulting to cough with phlegm or pus‚ chills‚ fever‚ and difficulty breathing. Bacteria‚ fungi‚ viruses‚ and a variety of organisms can cause pneumonia. But what if you are an immune-compromised host? When you already have a weakened immune system and you get pneumonia‚ it is called “pneumonia in an immune-compromised

in order to understand how an individual’s immunological phenotype is the result of its genotype‚ the environment‚ and development. For the first experiment‚ Dr. Brown’s research was testing how selection on basal and maximal metabolic rates affect immune function. In addition‚ Dr. Brown had four hypotheses for this particular experiment‚ two were for basal metabolic rate and two were for maximal metabolic rate. Moreover‚ trade-off with BMR decreases as basal metabolic rate increases‚ and assimilation

Outline and Evaluate research into the relationship between the immunes system and stress-related illness. Stress has been widely identified to be linked with illness‚ which has therefore attracted researchers to investigate the relationship between the immune system and stress. Cohen et al for instance conducted a study where 369 participants were asked to complete a questionnaire which measured their Psychological Stress Index‚ consisting of a scale measuring their own perception of their stress

Complement System The complement system is a nonspecific defense mechanism activated in response to invading organisms. This system gets its name from the fact that it complements the action of antibodies. It is the primary mechanism activated by antibodies to kill foreign cells by forming membrane attack complexes. In addition to directly lysing the invading organisms it also reinforces the general inflammatory tactics. It can be activated in two ways: 1. A nonspecific innate immune response

Acquired immune deficiency syndrome‚ or AIDS‚ is a recently recognized disease. It is caused by infection with the human immunodeficiency virus (HIV)‚ which attacks selected cells in the IMMUNE SYSTEM and produces defects in function. These defects may not be apparent for years. They lead‚ however‚ to a severe suppression of the immune system ’s ability to resist harmful organisms. This leaves the body open to invasion by various infections‚ which are therefore called opportunistic diseases‚ and

There has been extensive research into the link between stress and the immune system that shows that the link is indeed very strong with a positive correlation. The research is seen in the general adaptation syndrome‚ Stone’s experiment on stressful events and the links to symptoms‚ Cohen et al experiment on the common cold‚ and Keicolt Glaser who looked into immune function. Stress has been found to suppress the immune system allowing people to contract disease far faster than a person with less

Medicine and Disease Study Questions 1-10 1. Describe the role of the macrophage in the immune response. They are known as the vulture cells randomly engulf and destroy bacteria‚ cell debris or foreign matter. 2. State the origin and purpose of lymphocytes. The immune cells‚ or lymphocytes as well as macrophages provide the specific mechanism for the identification and removal of foreign material. Natural killer cells are lymphocytes distinct from the T and B lymphocytes. They destroy

Outline and evaluate research into relationship between the immune system and stress-related illness. The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs defending the body against foreign bodies (antigens). There are two types of lymphocytes… B cells… these produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells… if the invader gets

AIDS: Acquired Immune Deficiency Syndrome I am doing a report on AIDS‚ I don’t know much about AIDS but I will tell you what I know. I know that it is transmitted by sexual contact‚blood‚needles‚children during/before birth. I also know it affects the immune system directly‚ It is caused by the virus HIV which they have no cure for either AIDS or HIV at the current moment‚ but they are doing serious research on them. I call it the "Generation X Disease" because it mostly affects my sex- oriented
