At present this appears to be the only published report of a McArdle person with type 1 diabetes. There are several published reports that high levels of stored glycogen reduce the ability of insulin to stimulate the cells to take glucose from the bloodstream into the muscle cells. There has not been much research into insulin resistance in McArdle people, but it is an important topic. Personally, I wonder if future research will show that almost all McArdle people have some insulin resistance caused by the high amount of glycogen stored in their muscle cells, so I have included the following information. They hypothesised that insulin resistance would reduce the ability of the muscles to take up glucose during exercise and suggested that adding insulin (intravenously) would improve this. They found that when they artificially added insulin, it increased the amount of glucose able to get to the muscles, and increased the amount of work that the McArdle person was able to do. They found that the McArdle people had much less insulin-stimulated use of glucose than the unaffected people. It is likely that glucagon acted upon the liver, causing a release of glucose into the bloodstream. This would have acted in a similar way to having a sugary/glucose drink immediately prior to exercise, which is known to help McArdle people exercise more easily (section 7. The authors note that a similar improvement in the ability to exercise was seen after giving glucose, or glucose plus insulin (the insulin 130 would probably have helped the muscle cells to take up the glucose). Interestingly, the authors did not see an improvement in the ability to exercise when McArdle people were given insulin alone, without glucose. My personal unproven theory is that most McArdle people have some level of insulin resistance caused by glycogen storage in their muscle cells. This functions as a way of keeping the amount of glucose in the bloodstream constant. They gave each person a glucose drink, and investigated whether the body could use insulin to stimulate the muscle cells to take up the glucose. If this was the case, blood test results would show high blood sugar levels, but the McArdle person would feel that they had low blood sugar. Although studies have shown that some McArdle people have insulin resistance, these studies did not ask McArdle people whether they felt that their blood sugar levels were low. If this were the case, I wonder whether insulin resistance could lead to weight gain in McArdle people. If McArdle people have a feeling of low blood sugar, this would make the person want to eat a high sugar or high carbohydrate food. If the muscle cells are unable to take in glucose, the muscle will not be able to use the glucose to provide energy for movement. Exercise burns this fat, can prevent muscle wastage, and stimulate muscle development. However, the authors say that this affect will only last for approximately 48 hours. In addition, they found that regular training seemed to increase the ability of the muscles to use fat for energy. McArdle people with diabetes should obtain medical advice before using sugar/sugary drinks. Although McArdle people do not have muscle glycogen phosphorylase, brain glycogen phosphorylase is present. The presence of brain glycogen phosphorylase in the heart appears to be sufficient for it to function normally, and heart problems are not generally reported in McArdle people. In McArdle people, an increased (very rapid) heart rate is seen during intense exercise (before the second wind). The increased heart rate during exercise is only seen for a short period and when the muscle pain causes the McArdle person to stop and rest the heart rate becomes lower. However, this single case report is not sufficient evidence to support this theory. Angina is pain in the heart which is caused by narrowing of the arteries of the heart. Anti-cholesterol drugs called statins may therefore be prescribed, but these should be avoided if possible by McArdle people (see section 12. Measuring creatine kinase levels in the blood could indicate if muscle damage has occurred. Please contact Kathryn Wright if you are able to contribute more information about McArdle specialists and their details. Myoglobinuria is the most obvious sign of muscle damage which can be assessed by eye without any medical tests. You should discuss whether a low level of myoglobinuria could be treated at home (for example by drinking plenty of fluids), or whether you should go to a hospital each time. Discuss how to treat contractures; whether they will prescribe a strong painkiller (anecdotally McArdle people say that normal painkillers often are not strong enough to treat the pain of a contracture). If strong painkillers are prescribed, they should provide clear instructions about when and how. I attended the Oswestry clinic several times between the years of 2005 and 2008 as an observer where I was able to sit in on consultations between patients and Dr Quinlivan and other members of the team. The Oswestry clinic offers McArdle people an opportunity to meet specialists from several disciplines. Other members of the multi-disciplinary clinic include a physiotherapist who specialises in neuromuscular conditions, a dietician, and an exercise physiologist (who can measure the ability to exercise and help people learn to reach second wind). Dr Quinlivan also runs clinics for other muscle diseases at Oswestry, so her team are experienced at dealing with people with muscle diseases and any associated problems. The patient does not have to pay for the consultation, although it may be necessary to pay for any prescriptions required. In many other countries, patients must either pay for their consultation or have a health insurance policy which will cover the cost.

Similarly, asparagine and glutamine Sulfur-Containing Amnio Acids have amide R groups that are hydrophilic. During the process, a Lysine Histidine Arginine water molecule is produced and the covalent peptide bond is formed (Fig. This linear sequence of amino acids is termed the primary conformational structure of Acidic Amnio Acids protein molecules.

One of the key result in formation of a white residue, albumin practical problems with moving boundary electro (alba Latin for white), after the salt was removed phoresis was its inability to achieve a complete by dialysis and the water was evaporated. The development 14 of zone electrophoresis made it possible to over employing a liquid medium. For these studies, Tiselius devised a U-shaped electrophoretic cell come these difculties by providing a stable and employed a Schlieren band optical system to support medium in which proteins could migrate, detect the degree of refraction of light by proteins be stained and quantied. He found that then, offered the important feature of stabilizing there was a difference in the refractive index of the migration of the proteins that moving bound light at boundary interfaces between major protein ary electrophoresis could not achieve. However, it Tiselius dissolved a specic volume of a protein was not until the early 1950s that these techniques mixture in buffer, and carefully layered the solu were simplied and rigorously dened for practical 16 tion on the electrophoresis tube below the same use in clinical laboratories. As with movement of the cationic ions in the buffer the moving boundary technique, the migration of toward the cathode. Depending on the amount of individual proteins depended on the pI of the negative charge of the support medium, there will molecule, the pH of the buffer, electrolyte concen be an equal, but opposite (positive) charge of the tration of the buffer, and amount of current buffer in the adjacent support medium. However, the texture of the lter paper pull the molecules that have a weaker negative was found to be another important factor because charge, owing to their lower pI, toward the cath it offered substantially more resistance to the ode (Fig. These molecules are not moving movement of the proteins than was the case in the toward the cathode because they have a positive free-moving boundary system. Paper distance that human serum albumin would migrate electrophoresis was slow, requiring several hours may be greater on one brand of paper than on (often overnight) in order to achieve adequate another brand, the relationship between albumin separation of major protein fractions. Further and the subsequent major fractions was relatively more, it was opaque (frustrating early densito constant, and could be used to create a correction metric scanners), gave poor resolution, and had factor specic for that preparation of lter paper. It signicant problems with non-specic protein 19 was also observed that the type of paper affected absorption. To quantify proteins from individual the migration of smaller molecules less than larger molecules. An understanding of endosmosis is important in Application order to relate the migration of proteins to their (+) (+) surface charge.

If you have any of the signs or symptoms described in this chapter, it is important not to assume they are a result of having hepatts C. Your healthcare provider can determine if they are associated with your hepatts C. For troublesome and/or persistent problems, there are things you and your healthcare provider can do to either make them go away, or make them easier to live with. A sign is an abnormality detected by your healthcare provider during an examinaton. A symptom is something you, as a person with hepatts C, experience because of the virus. Signs and symptoms are discussed together because sometmes a sign is also a symptom. Your healthcare provider can take your temperature and detect a fever, so it is a sign. But if you have a fever, you experience its discomfort, so fever is also a symptom. The second secton reviews possible signs and symptoms that people with hepatts C who do not have cirrhosis may experience. The last secton reviews additonal signs and symptoms that people with hepatts C who have cirrhosis may experience. The second way the hepatts C virus causes damage is by provoking an immune response. An overactve or misdirected immune response can damage infected cells and the normal surrounding tssues. Experts now understand that hepatts C is not just a liver disease, but is a systemic disease, meaning it can afect nearly any organ of the body. As you read the list of possible signs and symptoms associated with hepatts C infecton, you may fnd some of the symptoms you have been experiencing that you thought were caused by something else may actually be caused by hepatts C. This is important because knowing why you are having a symptom is ofen the frst step in alleviatng the symptom, or making it less troublesome. Caring Ambassadors Hepatitis C Choices: 4th Edition Signs and Symptoms of Hepatitis C Without Cirrhosis the possible signs and symptoms of hepatts C without cirrhosis involve every organ system of the body. Although some of these symptoms can be quite uncomfortable, most of them do not indicate that your liver disease is getng worse. New symptoms should always be discussed with your healthcare provider so you can work together to keep your life with hepatts C as actve, productve, and enjoyable as possible. The lists are presented in alphabetcal order to make it easier to look up those signs and symptoms of interest to you. Frequent sites of joint pain are the hips, knees, fngers, and spine, although any joint can be a source of pain. Arthralgia associated with hepatts C can be migratory, meaning the discomfort moves from one locaton to another over tme. If you experience joint pain, it is important to talk with your healthcare provider before taking anything to treat the pain because some over-the-counter pain medicines such as acetaminophen are potentally harmful to the liver. However, fatgue can be severe, feeling like near exhauston even afer a full night of sleep. Fatgue experienced by people with hepatts C may also be accompanied by feelings of anger, hostlity, and depression. If this happens, you may wake up with your bedclothes and/or your sheets wet with sweat. Fluid retention Fluid retenton occurs when your body holds on to more water than it needs. Flu-like Syndrome People with hepatts C can experience periodic fu-like syndromes. The most common symptoms are fever, chills, headache, fatgue, and/or muscle aches. The lymph nodes of the armpits, groin, and neck are relatvely close to the skin surface, and are usually examined to see if you have lymphadenopathy. If you have lymphadenopathy, it may or may not be painful when you press on the swollen lymph nodes. Chapter 5: Signs and Symptoms That May Be Associated with Hepatitis C experience muscle aches or pain, it is important to talk with your healthcare provider before taking anything to treat the pain because some over-the-counter pain medicines are potentally harmful to the liver. They are most commonly seen on the face and chest, but can occur anywhere on the skin. More constant, cramping pain closer to the middle of chest, but under the ribs, can be due to gall bladder problems that may accompany hepatts C. If you experience any new pain in the abdomen, it is important for you to tell your healthcare provider right away so the source of the pain can be determined. For some, foods at room temperature or served cold are more appealing than hot foods. People with hepatts C should not drink any alcohol including beer, wine, wine coolers, and mixed drinks. If changes in your appette are causing weight loss, discuss this with your healthcare provider because good nutriton is partcularly important for people with hepatts C. Persistent diarrhea, especially if accompanied by weight loss, should be discussed with your doctor right away. Caring Ambassadors Hepatitis C Choices: 4th Edition indigeStion and heartburn Indigeston is typically experienced as an uncomfortable feeling of fullness in the stomach. It is ofen accompanied by queasiness and burping of a mixture of gas and stomach contents. When this occurs, you may notce a burning feeling in your throat and/or a sour taste in your mouth. Both indigeston and heartburn can be brought on by and last longer afer a faty meal. If the liver is not working normally, bilirubin can build up in the blood and begin to stain the skin. Although it is usually not accompanied by vomitng, nausea can be a very uncomfortable and debilitatng symptom. If you are experiencing nausea, talk with your healthcare provider because there are many ways to treat this symptom. You may fnd you cannot concentrate for long periods of tme, or may notce your thought processes seem slower than usual. You may have a hard tme coming up with words you want to say, or may just feel mentally tred. Always discuss cognitve changes with your doctor as they may or may not be related to hepatts C. Some of the symptoms of depression include: y sleeping more or less than usual y eating more or less than usual y hopelessness y helplessness y irritability y lack of interest in your usual activities y feelings of sadness and/or despair most of the time If you have one or more of these symptoms, you may have depression. Depression can seriously interfere with your quality of life and make it difcult for you to take care of yourself. If you have any of the symptoms of depression, talk to your healthcare provider right away. Others experience dizziness as disorientaton, or feeling as if the world is spinning around them. If you are experiencing dizziness, talk with your healthcare provider because this can be not only troublesome but also dangerous. If you are having headaches, talk to your healthcare provider before taking any medicines for your headaches because some over-the-counter pain medicines can be harmful to your liver. Mood swings may be related to depression, anxiety, or the medicatons you are taking. Most people with numbness or tngling feel it in their fngers and toes, but it may extend into the arms and legs. Peripheral vision, the ability to see things that are at the sides of your view, can also be diminished.
