Amino acid analysis in biological fluids, primarily homocysteine, appears to be very important clinical problem. Hyperhomocysteinemia increases the risk of early development of atherosclerosis, thrombosis, coronary and cerebral blood vessels, and is a predictor of death (Barker, n.d.). Existing analytical techniques are complex and costly, both in time and in finance. So, providing a simple and reliable technology is required. For example, thiols, including homocysteine, cysteine and glutathione, are transparent to UV rays, and are not captured by the chromatographic apparatus. This, incidentally, is tr...

- Issues Raised by Use of Turnitin Plagiarism Detection Software This past week, I worked with a couple of other members of the Writing Department at GVSU to prepare a position statement on plagiarism detection software. GVSU only recently acquired a subscription to Turnitin, and myself and the other teachers were concerned that teachers in other disciplines would be unware of the issues surrounding plagiarism detection services. The following is the full text of the statement which has been distributed on our campus.... [tags: Plagiarism Detection Software]

- Prostate cancer imaging with 18F-fluorocholine A combination of prostate-specific antigen (PSA) testing and transrectal ultrasound-guided biopsy is generally used for the detection of prostate cancer . However, conventional prostate biopsy, even using 6–12 needle samples, is susceptible to sampling error with a false- negative rate as high as 30–40% [18, 19]. In addition, postradiotherapy prostate biopsies are prone to problems in interpretation (due to the presence of radiation effects and the lack of knowledge of the time required for residual tumour to become nonviable after radiation ) and transrectal ultrasound-guided sextant biopsy typically understages disease in patients with...

- A titration is used to determine the amount of acid in a given solution. This is done by titrating a measured volume of acid (in this instance, acetic acid (CH3COOH)) with a solution of a strong base (usually sodium hydroxide (NaOH)), of a known concentration. The NaOH is added in small aliquots until the acid has been neutralised, and this can be determined with an indicator dye, such as phenolphthalein, or a pH meter (Nelson & Cox, 2008 pg58). In this practical, a pH meter was used and this allows for the acidity or alkalinity of a solution to be measured, and this was more accurate than using an indicator dye....

- An acid is a substance that produces H+ to form a solution that has a pH <7. It turns litmus paper red. It reacts with bases to form a salt and water. A weak acid is an acid that dissociates incompletely, releasing only some of its protons(H+). A strong acid is an acid that fully dissociates incompletely, releasing only some of its protons(H+). A base is a substance that can accept (H+) and releases(OH-) to form a solution that has a pH>7. It turns litmus paper blue. It reacts with acids to form a salt and water....

- Fat: My overall fat intake did fall into the AMDR, of 20%-35%, at 33.5%. My report also showed my intake of omega-3 and omega-6, also known as alpha-linolenic acid and linoleic acid. I did not meet the recommendation for either one of these. The recommendation for omega-3 is 1.1 gram; I took in only about 0.02 grams. While the recommendation of omega-6 is 11 grams, I only consumed about .28 grams. Both of these fatty acids are essential to growth. Omega-6 is metabolized in the body and turned into arachidonic....

- Some people think that acid rain can burn skin if it lands on them. This however, does not happen. Acid rain can not burn skin, it still can causes damage to plants, animals, and even structures. Acid rain occurs naturally without human interference, but since humans started to make objects that contribute to the creation of acid rain, it happens more frequently than if humans would not be involved. People not only raised the amount of acid rain that falls, they can also be the ones to bring the amount back down to reasonable levels.... [tags: Acid rain, Water, Volcano, Oxygen]

- The Use of ERGs for Early Glaucoma Detection Glaucoma is a degenerative disease which can be caused by high intraocular pressure (IOP) (Glaucoma, 2002). This IOP arises in the aqueous humor, the area between the cornea and the iris, where a drainage system allows the aqueous to drain from this area and recycle (Learn about Glaucoma, 2002). A specific balance of the production and removal of aqueous determines the IOP. Either malfunction or malformation of this drainage system can cause a rise in pressure....

- The Effects of Acid Rain on Statues Introduction ------------ During this investigation, I will use dilute hydrochloric acid as the acid rain and crushed calcium carbonate as the chemical of the statues. Then I will time how long it takes for the limestone powder to react until there is no more left when the acid is added to it. Rain contains acid naturally as it collects carbon dioxide from the air and makes carbonic acid. Rain normally has a pH of about 5.5 – it is slightly acidic due to the carbon dioxide dissolved in it.... [tags: Acid Rain Chemical Reactions Essays]

- Acid Rain Acid rain has become an environmental concern of global importance within the last decade. With the increasing environmental awareness of the "unhealthy" condition of our planet earth the concern about acid rain has not lessened. In brief, acid rain is rain with pH values of less than 5.6. When dealing with acid rain one must study and understand the process of making Sulfuric acid. In this project we will take an in depth look into the production of sulfuric acid, some of its uses and the effects of it as a pollutant in our environment....

- HAEMOCHROMATOSIS DETECTION USING PCR-RFLP INTRODUCTION Hereditary Haemochromatosis (HH), first described in 1865, is a genetic disorder of metabolism, characterized by progressive iron overload resulting from abnormalities in intestinal iron absorption and or release of iron from reticuloendothelial cells . It is an autosomal recessive disorder, where the body accumulates excessive iron, which is deposited in a variety of organs. Iron cannot be excreted, thus, the excess builds to toxic levels in tissues of major organs such as the liver, heart, pituitary, thyroid, pancreas, lungs, and synovium (joints)....
