|CAFFEOYL-CoA-3-O-METHYLTRANSFERASE.||The enzyme caffeoyl-CoA 3-O-methyltransferase, called CCoAMT below, catalyses the methylation of caffeoyl-CoA in a biosynthesis route, which has only recently been described, which leads from trans-4-coumaroyl-CoA to trans-feruloyl-CoA (Matern, U., and Kneusel, R. E. 1988, Phytoparasitica 16:153-170; Kneusel, R. E., Matern, U., and Nicolay, K. 1989, Arch. Biochem. Biophys. 269:455 to 462; and Pakusch, A. -E., Kneusel, R. E., and Matern, U., 1989, Arch. Biochem. Biophys. 271:488 to 494).
Under fungal attack, plants reinforce their cell wall very rapidly by incorporation of cinnamic acids, followed by cross-linking thereof to give polymeric structures or build-up of lignin. Under these conditions, feruloyl-CoA is the preferred acyl donor both for the esterification of cell wall polysaccharides and for lignification (reduction to coniferyl alcohol). The speed and extent of the change in the cell wall essentially determine the course of the infection and the fate of the plants, "hypersensitive reaction" characterising complete resistance of the plants, associated with a particularly severe and rapid change in the cell wall and the death of the cells directly affected. This hypersensitive reaction is also observed in the resistance reaction of plants to virus infections. It has only recently been discovered that feruloyl-CoA is not formed in vivo in all cases by activation of ferulic acid, but is also formed by reaction of coumaroyl-CoA. The caffeoyl-CoA-specific methyl-transferase which participates in this reaction has scarcely any homology with previously known enzymes (Pakusch, A. -E., Matern, U., and Schiltz, E., 1991, Plant Physiol. 95:137 to 143), is taxonomically widespread in plants and can be induced therein by, for example, fungal attack.

|CAPNOGRAPHY||monitoring of the concentration of exhaled carbon dioxide in order to assess the physiologic status of patients with acute respiratory problems or who are receiving mechanical ventilation and to determine the adequacy of ventilation in anesthetized patients.
Capnography is an indirect monitor of carbon dioxide concentrations in a patient s blood. During anaesthesia, there is interplay between two components: the patient and the anaesthesia administration device which is usually a circuit and a ventilator. The critical connection between the two components is either an endotracheal tube or a mask, and CO2 is typically monitored at this junction. Capnography directly reflects the elimination of CO2 by the lungs to the anaesthesia device. Indirectly

|CARDIOVASCULAR DISEASE||a disease of the heart (cardio) and blood vessels (vascular) often caused by a narrowing of the blood vessels, which is often due to accumulation of plaque in the lining of the blood vessels. CVD is the leading cause of disability and death in the United States, resulting in more premature deaths than any other illness.
|CARMUSTINE||See Abbrev.: BCNU|
|CAROTID ARTERY DISEASE||develops when the carotid arteries located in the front of the neck become blocked or narrow. These two arteries supply oxygen-rich blood to the part of the brain that controls movement, speech and sensation.
If the cells in this area of the brain are depleted of oxygen, they die, which results in permanent damage or stroke.
How do the Carotid Arteries Become Blocked?
When plaque, made up of scar tissue, cholesterol and other fatty substances, begins to build up on the inside of the artery walls, this is called atherosclerosis or "hardening of the arteries". Not only does this buildup narrow the artery passages and slow the flow of blood to the brain, pieces of plaque and/or blood clots sometimes break away from the artery walls and become lodged in the brain's smaller arteries.
This atherosclerotic process significantly increases the likelihood of stroke.
Most people with carotid artery disease (CAD) have no symptoms. Symptoms typically present themselves in the form of a transient ischemic attacks or mini strokes as they are called. During a transient ischemic attack (TIA), a person may experience temporary blindness, weakness in an arm or leg, dizziness, tingling sensations on the surface of the skin or numbness. These mini attacks (TIAs) rarely last more than 30 minutes, but people who have them are twice as likely as those who don't to have full-blown strokes.
The risk factors for CAD are the same as those for coronary artery disease. These include smoking, diets high in fat, sedentary lifestyles, and a strong family history of heart disease or stroke.
|CAROTID ENDARTERECTOMY||a surgical procedure designed to clean out material occluding an artery) done on the carotid artery (a major artery in the neck that supplies blood to the brain) to restore normal blood flow through it to the brain and prevent a stroke.
|CARTILAGE. JOINT CARTILAGE||Cartilage is a slippery and resilient tissue produced and maintained by its own specialized cells. It cushions the surfaces where two or more bones form a flexible joint. When you do even the simplest exercises or everyday activities there is tremendous pressure on your joints. Cartilage, joint fluid, and underlying bone work together like a shock absorber allowing flexible joint function.
Because cartilage lacks a direct blood supply, nutrients must pass into the cartilage from surrounding tissue. These nutrients sustain cartilage cells and provide the components necessary to maintain a healthy cartilage structure.
Scientists are not sure about all the factors that cause cartilage breakdown; however, they have discovered enzymes that play a role in the process. With age, injury, or over-activity, this process of breakdown can exceed the process of replacement leading to problems in the joints. These problems result in less flexibility.

|CELIAC DISEASE||is a chronic intestinal disorder caused by a specific intolerance to gluten present in wheat and rye proteins leading to changes in the small intestinal mucosa and impaired absorption. Current treatment is effected by a well balanced gluten-gliadin free diet high in calories and proteins and normal in fat. This excludes cereal grains with the exception of rice and corn. Those patients with celiac disease who do not respond to the glutengliaden free diet are given glucocorticoid steroids such as hydrocortisone, prednisone or prednisolone|
|CELL CYCLE||The sequence of events between cell divisions. The cycle is conventionally divided into G0, G1, S, G2 and M phases|
|CELLULAR IMMUNITY||Immunity that is due to cell-bound antibodies, in contrast to humoral immunity

|CELLULASE||Enzyme converting cellulose into glucose|
|CENTRAL VENOUS CATHETER OCCLUSION||Patients with cancer and other serious diseases often receive a central venous catheter to deliver vital therapies including chemotherapy, nutritional support, pain management, antibiotics and blood products, and to withdraw blood samples for testing. An estimated five million central venous catheters are placed in patients each year in the United States,1 and approximately 25%, or 1.25 million, become occluded by blood clots.2 Known as CO, this obstruction in a central venous catheter can impair the ability to infuse fluid through or withdraw fluid from the catheter. Because central venous catheters are primarily inserted in patients receiving life-saving medications, it is critical to restore patency (flow) in a timely manner with minimal risk to the patient.
|CEREBRAL ANEURYSM||Cerebral aneurysms occur when there is abnormal pressure on sections of brain arteries, causing a balloon-like out-pouching of the arterial wall. As the aneurysm expands, the wall becomes thinner and the possibility of a rupture increases. If the aneurysm ruptures, this causes hemorrhaging that can lead to severe disability, coma or death. Cerebral aneurysms are present in 3% of the population, but remain asymptomatic until the day they rupture and cause a cerebral hemorrhage. Increasingly, advances in imaging technology allow doctors to detect the presence of aneurysms before they rupture, increasing the appeal of less invasive and safer preventative endovascular treatments|
|CEREBRAL PALSY||collective name given to a range of conditions caused by brain injury caused at or around the time of birth, or in the first year of an infant's life. The brain injury may be caused, for example, by trauma during delivery. It may also arise through such causes as trauma due to road traffic accidents or meningitis during the first year of life. It has been found that there is an increased risk of cerebral palsy in prematurely born babies and, as a result of the improvements in technology which enable premature babies to be kept alive from a much earlier age, the incidence of cerebral palsy in many countries is actually increasing rather than falling.

An enzyme, commonly chymosin, is next added to coagulate casein, the major milk protein - into a soft solid, or curd, that consists of Ca caseinate & milkfat.
The remaining liquid - the whey, which contains soluble proteins & lactose - is next removed to leave the fresh cheese. The curd is then stirred & heated, salt is added or the curd may be treated with brine, & the cheese is pressed into molds
|CHEMICAL GENETICS||Other terms used interchangeably with chemical genetics include chemical genomics, chemogenomics & chemical biology.
Chemical genetics, as most commonly defined, involves the use of small molecules to perturb, understand & control the cellular & physiological function of proteins. Just as geneticists use mutations to perturb cellular function, researchers can use small molecules to activate or inactivate gene products. Small molecules are used, in effect, as switches

|CHRONIC COUGH||Chronic cough is defined as a cough that lasts for more than three weeks. More than 90 percent of cases of chronic cough result from five common causes: smoking, postnasal drip, asthma, gastroesophageal reflux and chronic bronchitis. Although in most patients chronic cough has a single cause, in up to one fourth of patients, multiple disorders contribute to the cough. A stepwise evaluation in patients with chronic cough can minimize the invasiveness and expense of the work-up. Initial screening of patients with chronic cough should search for smoking, occupational exposure to an airway irritant, cough-inducing medications, airway hyperresponsiveness following upper respiratory infection, chronic bronchitis or any systemic symptoms suspicious for serious disease. Patients who are not diagnosed after an initial screening are evaluated or empirically treated in a stepwise fashion for postnasal drip, asthma and reflux. Bronchoscopy is reserved for use in the few patients still without a diagnosis after the previous steps have been completed|
|CHRONIC GRANULOMATOUS DISEASE||is a life-threatening congenital disorder that causes patients, mainly children, to be vulnerable to severe, recurrent bacterial and fungal infections. This results in frequent and prolonged hospitalizations and commonly results in death.|
|CHRONIC NONBACTERIAL PROSTATITIS||is the inflammation of the prostate not due to bacterial infection. It refers to a condition affecting patients who present symptoms of prostatitis without a positive result after urine culture or expressed prostate secretion (EPS) culture.
Nonbacterial prostatitis is typically a chronic, painful disease. The symptoms characteristically go away and then come back without warning. The urine and fluid from the prostate show no evidence of a known infecting organism, but the semen and other fluids from the prostate contain cells that the body usually produces to fight infection.
Treatment with antibiotics and drugs that relax the muscles of the prostate gland is often tried and commonly fails. It is the least understood type of prostatitis and hardest to treat. This form of prostatitis is the most common. It is believed to occur eight times more often than bacterial prostatitis. It occurs in association with other diseases such as Reiter syndrome (arthritis, conjunctivitis [eye inflammation] and inflammation of the genital and urinary systems).

Cintilografia Miocárdica com esforço e repouso É um teste ergométrico que inclui a utilização de um marcador radioisotópico no momento em que se atinge o máximo do esforço. Depois do exercício, o paciente deita-se em uma maca e são tiradas fotografias com uma câmara especial que vê como o marcador se distribuiu no músculo do coração. Se uma área do coração não recebe a quantidade normal de sangue, haverá um defeito na imagem produzida, porque o nesse caso o marcador não chegou a essa área. As imagens feitas após o exercício são comparadas às realizadas em repouso. O fluxo sanguíneo que é normal durante o repouso, mas anormal durante o exercício (um defeito de perfusão) é uma indicação de que o coração não está recebendo sangue suficiente.

|COMPENSATORY HYPERINSULINEMIA||When target cells are unresponsive to insulin, the pancreas responds by pouring even more insulin into the bloodstream, leading to high levels of the hormone in the blood, a condition called compensatory hyperinsulinemia. The high level of insulin in the blood forces glucose into cells but also starts the events leading to arterial damage and eventually a heart attack. Under these conditions, a person may not manifest either diabetes or heart disease but could well be on the way to either or both.
|COMPLEMENT (IMMUNE SYSTEM).||Complement forms part of the body's natural immune system, the activation of which plays a key role in the normal inflammatory response. Complement is activated when there is an injury or cellular attack in the body. For example, if a bacterium or virus enters the body, complement is activated by antibodies that recognize the invader and fight off the invading organism. Likewise, if a foreign substance enters the body, which could range from a wood splinter to a medical catheter or even a transplanted organ, it is the complement system that is intimately involved in protecting the body by mounting an inflammatory response|
