Uses Of Autoolochemistry System And The AU Chemistry Analyzer Models

Rheumatoid Arthritis(RA) is the most common type of autoimmune arthritis. RA is a progressive and debilitating musculoskeletal disorder that affects the joints symmetrically, causing a range of systemic effects. What it causes is still not well known; nevertheless, findings of new research points towards a believe that it is triggered by a defective immune system, which causes the release of inflammatory chemicals. These chemicals cause damage to cartilage and bone, usually affecting the wrists, the joints of the hand, including the knuckles, the middle joints of the fingers and feet. While this condition can affect any joints, besides, important body organs such as the eyes and the lungs can also be affected by the inflammation that occurs as a result of this chronic condition. Only in America 1.3 million of people are affected by this ailment, and 75 % of them are mainly women. Its onset usually occurs between fourth and sixth decades; however, RA can occur at any age("Diseases And

Gel electrophoresis method. Qualitative analysis shows protein concentrations in kidney, heart, and liver. 1-6 are kidney tissue. 7-14 are liver and 15-19 are the heart tissue.

1964). There was a statistically significant effect of time spent in the blocking solution and the fixative and staining quality. In future experiments, the time samples are placed in blocking solution and fixative should be monitored more closely and left for a sufficient amount of time to get better and more accurate results, concerning staining quality. On the contrary, there was a positive correlation between the amount of time the samples were left in the antibody solutions and staining results. The longer the samples were left in the antibody solution, the better the staining results were as attested by the statistical

Some people with lupus have a greater ratio of proinflammatory to anti-inflammatory cytokines than normal individuals, which produces an unbalanced regulatory mechanism. While an overall cause-and-effect relationship between cytokines and lupus is not yet understood, certain cytokines called interferons and interleukins are associated with the disease. Complement protein interact in a sequential manner to clear immune complexes from our body. Deficiencies of certain complement proteins are associated with lupus. In addition, since complement proteins are consumed during inflammatory processes, low complement levels may indicate lupus

It is usually know as rheumatoid arthritis, but this disease is one caused by the patient’s own body against itself. The body produces proteins that attack healthy tissue causing it to be an autoimmune disease. The true cause of rheumatoid arthritis is unknown but could be due to certain viruses, bacteria, fungi or due to genetics. The diagnosis of RA is established usually on clinical criteria and serologic results in the lab. Usually rheumatoid factor, which is an antibody specific for the Fc portion of the human IgG, this has been a marker used by doctors to help diagnose RA. The detection of elevated serum levels RF IgG antibodies has been almost exclusively confined to rheumatoid arthritis patients, not patients with other types of arthritis. The first of the symptoms one is looking for is the inflammation within joints of the body and inflammation causing stiffness and soreness to the patient. One may also experience fatigue from the inflammation and fever. When trying to figure out if a patient is infected with rheumatoid factors a doctor may run a number of tests to deliver a confirmatory diagnosis. One of the most simple and crude ways to test for this is ESR which is also known as Sedimentation Rate. This test helps to the doctor if there is inflammation within the body. The test results show that if someone has higher levels of inflammation in their body the sedimentation rate results will be higher. Another test to help doctors see if there is inflammation within the body is the C-reactive protein test. Both of these tests are done when your doctor suspects that you have an acute condition causing inflammation, such as a serious bacterial or fungal infection or when you are suffering from an inflammatory disorder such as arthritis, an autoimmune disorder such as rheumatoid arthritis. The gold standard of testing for RA is the CylicCitrullinated Peptide Antibody, this

For example rheumatoid factor (RF), an antibody directed against the Fc portion of immunoglobulin G (IgG) molecules. It presents in approximately two thirds of patients with RA (79). Although the presence RF is used for diagnostic purposes, 10% of healthy individuals and many patients with other autoimmune disorders, involving Sjogren,s syndrome, systemic lupus erythematous (SLE), and mixed connective tissue disease, also express RF(80). In addition, about 70% of hepatic patients with chronic hepatitis C virus are RF positive (81). The diagnostic protocol for RA has included laboratory testing for RF for more than 50 years, but the presence of RF as a marker for RA in patients is considered unreliable as it presents in the general population and in other autoimmune and infectious diseases. However, decline in RF levels indicates regression in RA activity, as it is an indicator of a given patient’s response to treatment when various disease-modifying anti-rheumatic drugs and other biologics, such as infliximab or rituximab, are administered

composed of a membrane-bound antibody that, like all antibodies, has a unique and randomly determined antigen-binding

Rheumatoid arthritis(RA) is a typical, chronic autoimmune disease that primarily affects the joints, ultimately leading to synovitis that often develops into cartilage and bone erosion, apart from which, extra-articular features are presented, including sub-cutaneous nodules, vasculitis and pulmonary fibrosis, particularly in severer cases. Animal models of RA have proven to be useful tools for pre-clinical reasearch as well as for the study of pathogenesis due to the fact that animal

Therefore, according to the obtained results, this protein has proper antigenicity strength and possesses epitopes similar to the natural form and hence can be used to design diagnostic kits. False negative results were only seen in three samples of the patients. The reasons of failure can be due to consumption of proton pump inhibiting drugs or bismuth, watery diarrhea, possible increase in plant materials in the diet which results in stool weight increment, and polysaccharide inhibitors. In addition, false negative results may arise from problems confronted in Western blot technique such as reduction of the primary antibody concentration, decreased antigen level, proteolytic cleavage and inactivation of antigen, increased time and transfer temperature,

In clinical trials, rheumatoid arthritis is diagnosed formally by using seven American Rheumatism Association (ARA) criteria. The typical outpatient practice, a definitive diagnosis using these criteria may be difficult to obtain early in the disease process. During the initial visit, patients should be asked about degree of pain, duration of stiffness and fatigue, and functional limitations. A careful joint examination looking for the characteristics described above is vital (Rindfleisch & Muller, 2005) and other diagnostic tests can also be performed. The initial and most simple way of diagnosing is to take an X-ray. This can help the doctor to differentiate RA from

Thus, primary and secondary antibodies are used to recognize the antigen of interest (CRP). The secondary antibody is used to recognize the constant regions of the primary antibody. In this case, the primary antibody is the antigen. Thus, an immunoblotting analysis is done. An immunoblotting analyses allows the antibody to bind to immobilized antigen in vitro. Additionally, immunoblotting uses nitrocellulose paper for the proteins to bind to as the proteins natural stick to the nitrocellulose paper. The nitrocellulose membrane is the block in the solution containing milk protein (blotto). This blotto binds to the nitrocellulose and prevents non-specific binding of antibodies. Consequently, the primary antibody (antiserum or anti-CRP) is incubated with blotto at room temperature. After incubation, unbound antibody is washed away fore adding the secondary antibody. The secondary antibody usually alkaline phosphatase is added in with blotto and incubated at room temperature. Once again unbound antibody is washed away before adding the substrate. The substrate is then added and the signal is allowed to develop as the substrate changes in color from yellow to purple. Therefore, the primary antibody must be present for the secondary antibody to bind to. The change in color from yellow to purple only forms when the entire complex is present as the substrate precipitates. As a result, the

Antibodies are proteins made by the immune system where they recognize and combat infectious diseases (Feldt, 2012). However antibodies can mistakenly target, damage and attacks the body’s own tissues as being foreign or dangerous, these are called autoantibodies.

Rheumatoid Arthritis is based on a history and physical, physical examination, and laboratory tests of anti-nuclear antibody (ANA) rheumatoid factor (RF), anti-cyclic citrullinated peptide antibodies (ACPA), CRP, and ESR. The American College of Rheumatology teamed with the European League against Rheumatism to develop classification criteria in 2010. If the patient has 2-10 large affected joints, symptom duration over 6 weeks, and above the upper limit of normal ESR and CRP he will receive one point each. They receive two points for 1-3 small joints affected and a low positive of RF and ACPA. Three points are scored for 4-10 small affected joints, and a high positive of three times the normal of RF and

Every antibody is composed of four polypeptides; two light chains and two heavy chains. These chains form together to make a “Y” shaped molecule with the heavy chains on the inside making the general shape and the light chains on the top outer edge of the protein. The light chain is composed of approximately 214 amino acids and the heavy chain is composed of about twice as many amino acids. There is also a vast amount of amino acid sequences at the ends of the protein that makes each one different from the others. The top end of the antibody is known as the variable region, composed of approximately 110-130 amino acids, and is what gives antibodies their specificity and uniqueness for binding to certain antigens
