Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CAD. Cholesterol is carried in the blood stream by molecules called lipoproteins. Cholesterol is made from eating fatty foods, excess alcohol and caffeine etc. Which means that the more of these you eat the more likely you are to suffer from CAD 3) Carbon monoxide, nicotine, and other substances in tobacco smoke can promote atherosclerosis and trigger symptoms of coronary artery disease. Smoking: * Causes the platelets in your blood to clump together easily by making your blood cells more "sticky" and more likely to form clots.
Children get it by inheriting it from their parents. Is a storage disease in which harmful quantities of a fatty substance called ganglioside build up in tissues and nerve cells in the brain. The condition is caused by insufficient activity of an enzyme. This disease is has various preventions, Symptoms, causes, forms, and treatments. There are two forms of Tay-Sachs.
The truth is: It’s both. As a lipid, a substance with an oily or waxy nature, cholesterol is a vital element in cell membranes, a main component in hormones, a protective coating for nervous tissues, and allows certain biological acids to digest and process foods. However, anything taken in excess can produce dangerous effects. This same chemical that is essential for the proper function of the body can also cause of some extremely serious medical conditions. An excess of cholesterol has been linked in many cases to leading to heart attack, stroke, or atherosclerosis (fat deposits on the inner walls of arteries).
Beta vulgaris root tonoplast and cell membrane permeability increase through immersion in solution of high solvent concentration. Beta-vulgaris ‘s red pigment along with ethanol will be used to determine the stress that ethanol has on biological membranes. Research Question What is the effect of changing the percentage of ethanol concentration in the absorbance over time of beetroot pigment? Variables * Independent Variable: Concentration of Ethanol (10,20,30,40%) * Dependent Variable: Absorbance measured by the Logger Lite (nm) * Control Variables: Pieces of Beta vulgaris (cm). Hypothesis: If the there is a large amount of ethanol used, then ethanol will destroy the plasma membranes of the cells of beetroots, because if the concentration increases, the membranes will break even more which will result in greater expulsion of beetroot pigments from the cells.
Causes Phenylketonuria (PKU) is an inherited, autosomal recessive disorder (Letcher, 2002). It is caused by alterations or mutations in the genetic code for the phenylalanine hydroxylase (PAH) enzyme (Letcher, 2002). Mutations in the PAH gene prevent the liver from producing adequate levels of the PAH enzyme (Letcher, 2002). This enzyme phenylalanine hydroxylase is required to convert the amino acid phenylalanine into amino acid tyrosine (Letcher, 2002). If this reaction does not take place, phenylalanine accumulates and tyrosine
These consequences affect all the organ systems in the body. (Carol Mattson Porth, Glenn Matfin 2009) Cause: The presented patient scenario along with the information given indicate that Ms. Smith suffers from ARF that is caused by severe dehydration. This severe dehydration in turn produces Prerenal acute renal failure due to decrease renal blood flow and decrease glomerular perfusion and filtration. Based on the above patient diagnosis the labs would be as follows: K or potassium will be elevated to more than the normal ratio: K >5 Creatinine elevated: >2 Bun elevated: >20 Urea & sulfate will be elevated Sodium levels will be normal or low Calcium will be low & phosphate will be high. Hgb will be low: <12 Urinalysis: patient has low urine output and urine will have low specific gravity.
Coronary Artery Disease (CAD) is defined as a disease where the coronary arteries, arteries that supply the heart muscle, are clogged with plaque. CAD is also called coronary heart disease. Plaque comes from the fat and cholesterol in a person’s diet. Plaque builds up over time. When plaque builds up in the arteries, it reduces, or eventually blocks where blood can flow.
The pancreas is an organ located behind the stomach that produces chemicals called enzymes, as well as the hormones insulin and glucagon. These enzymes are usually only active after they reach the small intestine, where they are needed to digest food. When they somehow become active inside the pancreas, they digest pancreatic tissue causing swelling, bleeding and damage to blood vessels. Acute pancreatitis affects men more often than women. Certain diseases, surgeries, and habits make one more likely to develop this condition.
Lipids and carbohydrates allow fuel to be utilised as energy, whilst proteins help maintain cells by growing and repairing them (Rolfes, Pinna & Whitney 2012, p.9). Essential vitamins are those that the body requires but must gain them from food and help release energy from protein, lipids and carbohydrates (Rolfes, Pinna & Whitney 2012, p.10). Whilst minerals are utilised by the body to put structures together such as teeth and bones and water is essential to carrying waste away and for the transportation of minerals (Rolfes, Pinna & Whitney 2012, p.11). However, people require differing amounts of these nutrients throughout their life cycle and are also dependent on gender, age, lactation and pregnancy (National Health and Medical Research Council 2014).
The use of methamphetamine is associated with long-term biochemical and structural effects on the brain and significantly changes how the brain functions. The excessive production of dopamine causes neuropathological changes in the brain and has a neurotoxic effect on the brain cells that store dopamine and serotonin. These changes include decreases in the levels of dopamine transporters as well as decreases in the density of serotonin transporters in various parts of the brain. Studies have demonstrated that daily use of methamphetamine results in increased cell death in the brain, which would have a negative effect on prefrontal cortex functioning. Changes in the activity of the dopamine system are associated with reduced motor skills and impaired verbal learning.
