Rheumatoid arthritis is a disease that has direct involvement with the immune system. This disease is considered to be degenerative and currently the only thing that can be done is manage the painful symptoms and suppress the self targeting actions by using immune suppressing drugs. The cause of rheumatoid arthritis is mostly unknown but there is a high amount of evidence that there are genetic predispositions for the disease. This being said however there are also environmental factors to asses these include, bacteria, viruses, fungi and other environmental factors. Doctors primarily use a physical examination to first suspect R.A. then send for blood work to confirm. There are many aspects to this disease and many questions left unanswered, the treatments available now are only temporarily and can in some cases cause more problems than benefits. Lab experiments and clinical trials are currently showing some great results and could within our lifetimes cure many autoimmune diseases including R.A.. Although much is unknown on the causes of R.A. there are many things we see in correlation with the onset of disease. These include Bacterial, viral, and fungal infections. The mycoplasma bacteria, Epstein-Barr virus, cytomegalovirus, parvovirus and rubella (German measles) virus have all been considered as possible causative factors but conclusive evidence is still lacking (Zeliadt, 2010). Many times there have only been considerations for infectious bacteria causing this disease but now that idea is being questioned. A study involving mice in bacteria free cages showed that the friendly gut dwelling segmented filamentous bacteria (SFB) can cause onset of R.A. in greater numbers than those without. The mice that did no... ... middle of paper ... ...Retrieved Febuary 1, 2012, from About.com: http://arthritis.about.com/od/radiagnosis/a/rheumfactor.htm HJ, W., II, I., J, D., K, H., T, S., Y, U., et al.

In this experiment, we determined the isotonic and hemolytic molar concentrations of non-penetrating moles for sheep red blood cells and measured the absorbance levels from each concentration. The results concluded that as the concentration increased the absorbance reading increased as well. A higher absorbance signifies higher amounts of intact RBCs. The isotonic molar concentration for NaCl and glucose is 0.3 M. The hemolysis molar concentration for NaCl and glucose is 0.05 M. Adding red blood cells to an isotonic solution, there will be no isotonic pressure and no net movement. The isotonic solution leaves the red blood cells intact. RBC contain hemoglobin which absorbs light, hemoglobin falls to the bottom of the tube and no light is absorbed. Determining the isotonic concentration of NaCl and glucose by finding the lowest molar concentration. In contrast to isotonic molar concentration, hemolysis can be determined by finding the
Jennifer Ackerman's main focus in her article The Ultimate Social Network, is that of the functions concerning bacteria within humans. Although scientists have had presumptions about humans being proficient in governing their body’s innermost structure, they soon come to recognize the sophistication of our inner space which holds an extensive plethora of bacteria and other microorganisms that lie within each and every one of us. Moreover, scientists' new and emerging view of how the human body operates, and the cause of increasing present-day diseases (i.e. obesity and different autoimmune disorders) are uncovered by analyzing effects of certain microbe species in our bodies. By italicizing on points such as the above, in conjunction with bacteria's genetic variations, and modern computing technology, the author proves that scientists are quickly progressing with the characterization the most prevalent species of microbes, which, in her opinion, is definitely paying off.

In addition to its traditional clinical manifestations, GAS can also cause serious invasive disease such as necrotizing fasciitis, colloquially known as the flesh-eating disease. First broadly reported during the Civil War, when it was known as gangrene, necrotizing fasciitis occurs when an individual’s subcutaneous fat and superficial fascia become rapidly necrotic. Though incidence data is limited, one study estimated that, worldwide, there are approximately 660,000 cases of invasive GAS disease per year, with 97% of those cases occurring in low-income populations (4). Many microorganisms other than GAS have been linked with necrotizing fasciitis, including Staphyloccocus aureus, Escherichica coli, and Klebsiella pneumoniae, and the disease is often caused by a polymicrobial infection. However, the most well known causative agent in necrotizing fasciitis cases is usually Group A streptococci (6). Although risk factors for necrotizing fasciitis include diabetes, old age, and immunosuppression, nearly half of all infections occur i...
Rheumatoid arthritis is a chronic inflammatory and an autoimmune disease that occurs when the immune system mistakenly attacks the body’s tissue (Rheumatoid arthritis, 2017). This disease affects the entire body, which is called a systemic (means entire body) disease. Arthritis is derived from the word part arthr-, which means “joint,” and -itis, which means “inflammation,” so altogether it means “inflammation of the joints.” It creates inflammation that causes the tissue that lines the inside of joints (synovium) to thicken. About 1.5 million people in the U.S. are affected. It affects all races, but it affects three times as many women than men (What is Rheumatoid Arthritis, n.d.). Overtime, rheumatoid arthritis causes painful swelling that can potentially result in bone erosion or joint deformity, which leads up to physical disabilities. RA can affect more than just your joints, but can spread to body systems, skin, eyes, lungs, heart, blood vessels, e.t.c (Rheumatoid arthritis, 2017).
Arthritis affects people of all age groups. More than 100 types of arthritis are known. Among these osteoarthritis and rheumatoid arthritis having the highest incidence. One of the major causes of chronic debilitation in industrialized nations is Osteoarthritis which results from damage to the joints, which may be due to trauma, infection, or age-related wear. Rheumatoid arthritis is encountered less frequently than osteoarthritis and is estimated to affect around one per cent of the world’s population. Amongst patients of Rheumatoid arthritis, women are three times more likely to be affected by this condition than men. This condition is caused by an inflammatory process where the body starts attacking itself. Rheumatoid arthritis also affects several joints, with inflammation sometimes seen in and around the lungs, the heart, the eyes and the skin. The most commonly reported complaint by arthritis patients is pain. The pain might be from the joint itself and be a result of inflammation, damage from the disease, or through daily wear and tear. Muscle pain is also common and is caused by having to force movements against stiff and painful joints. Although range of movement in the affected joint may be limited and uncomfortable, physical exercise has been shown to benefit those with arthritis. Physical therapy has been shown to significantly improve function, decrease pain in the long term and delay the need for surgery in advanced cases. The majority of arthritis cases occur among theelderly, however the disease can occur in children as well. Over 70% of the population that get affected by arthritis in North America are over the age of 65 (4). The disease occurs more commonly in females than males in all races, age groups, and ethn...
The term arthritis refers to the joint inflammation. Joint facilitates the movement of body parts. Over the 100 different forms of arthritis, osteoarthritis and rheumatoid arthritis are common. It has been estimated that over 350 million people worldwide are affected by arthritis.
It is still unknown what the cause of Rheumatoid Arthritis is but there are some theories that have not been proven. The oldest theory states that viruses and bacteria are the cause of Rheumatoid Arthritis. Now with all the research being done, scientists believe that Rheumatoid Arthritis is hereditary. Specific genes have been found to make people more likely to get Rheumatoid Arthritis. Some scientists also think that some environmental factors and infections might cause the immune system to attack. Contributing factors are smoking and being exposed to silica metal. So although the exact causes are unknown, the result is that the immune system is ready to make the joins and tissues inflamed by activating immune cells.

Arthritis occurs when the body incorrectly identifies its own tissue as foreign matter and attacks it. Arthritis includes a set of more than eighty autoimmune diseases. Arthritis attacks connective tissues and joints. It causes stiffness, pain, inflammation, and swelling of the joints. Some kinds are crippling, but rarely leads to death. There are many different kinds of arthritis, the main ones being Osteoarthritis and Rheumatoid arthritis; others include gout and ankylosing spodylitis.

One of the most common mysteries in the world is the development of autoimmune diseases. An autoimmune disease is when the immune system, which usually keeps your body healthy thinks that your healthy cells are antigens and attacks them. This is irony right? It is against properties of evolution for an immune system to attack itself causing sickness and possibly death if untreated. There are about 80 different types of autoimmune diseases, which usually have periods of little to no symptoms and worsening symptoms. What particularly creates confusion in the world is the autoimmune disease, inflammatory bowel disease, which affects almost about five million people worldwide.
