Celiac disease: an often missed diagnosis Commonly referred to as wheat allergy‚ celiac disease is not an allergic disorder; rather it is actually intolerance to gluten‚ a protein in wheat. It is also known as celiac sprue‚ nontropical sprue and gluten-sensitive enteropathy. Celiac disease occurs in people who have a genetic susceptibility. It was considered a north European disease initially but now it has a high prevalence in all the continents. In north- India it affects 1 in 200-300 individuals

allergens‚ your immune system treats the allergen as an invader and mobilizes an attack. The immune system does this by generating large amounts of a type of antibody (a disease-fighting protein) specific to the particular allergen you’re allergic to. In the case of pollen allergy‚ the antibody is specific for each type of pollen: one antibody may be produced

Lymph nodes act as a drainage system‚ they also produce antibodies and lymphocytes. C. What are the two functions of the spleen?

“Hemophilia is a rare bleeding disorder in which the blood doesn’t clot normally. Hemophilia usually is inherited. People born with hemophilia have little or no clotting factor (a protein needed for normal blood clotting).... These proteins work with platelets to help clot the blood. Platelets are small blood cell fragments that form in the bone marrow. When blood vessels are injured‚ clotting factors help platelets stick together to plug cuts and breaks on the vessels and stop bleeding. The two

together to perform a role. Antibodies are specialized proteins which are secreted by B cells in a response to non-self antigens. Antibodies are made up of four polypeptide chains which are held together by disulphide bridges. There are two longer and two shorter chains which look like the letter “Y”. The ends of the antibodies have a variable region which is specific to a particular antigen. An antigen and antibody are complementary to each other and form an antigen-antibody complex.

Infectious Disease Case Study Assignment After reviewing this case study‚ address these questions: 1. West Nile fever is caused by the West Nile virus. Describe the emergence of novel disease in the Western hemisphere. Provide some examples of sources of infection for novel diseases‚ including the mode of transmission for WNV. Why is this a concern? In late August of 1999‚ an unusual cluster of encephalitis cases was reported to NYC’s Department of Health. Laboratory sequencing of virus isolated from brain tissue of birds

is pretibial myxedema. This causes the skin to develop red irregular patchy skin. Moreover‚ all these symptoms are caused by the effects of the autoimmune disorder causing your body to attack itself. This occurs by releasing an excess amount of antibodies called thyroid-stimulating immunoglobulins (TSIs) throughout the body. This then causes them to be pushed into the tissues causing the swelling and inflammation. As for the causes of Grave’s diseases‚ it is not fully understood yet since it is an

immunity. Protection can be acquired either by passive or by active immunization.Passive immunization involves transfer of antibodies obtained from an immune donor to a nonimmune individual and results in temporary immunity. Currently‚ antibody-based therapies represent a form of treatment for disorders induced by venoms or toxins and for viral infections. Injections of antibody preparations derived from immunized human donors are used for the prophylaxis and treatment of tetanus‚ rabies‚ and pneumonia
