Secondary excitotoxicity is thought to be more relevant to chronic neurodegenerative disorders than the classical acute form. In this pathway increased glutamate levels are not required as disturbances with the neuronal resting membrane potential cause glutamate receptors to be over-activated by physiological levels of glutamate. In a neuron which is affected by another pathological process and shows reduced ATP production‚ Na+ dysfunction or impaired glucose metabolism and as a result has an abnormal

I. I haven’t heard of FFP during the first semester actually. I just knew that the following semester I would be needing a white book with a flame print on it. I really didn’t care about the subject so much even though I was already attending the classes. To tell you the truth‚ I thought that FFP would be the simplest subject in my load but as it turns out‚ it proved to be quite stressful. Not bad stressful but good stressful‚ okay‚ maybe sometimes bad stressful. I learned a lot of values from this

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

compounds that do not meet the guidelines of a true chelate. Chelators are used in producing nutritional supplements‚ fertilizers‚ chemical analysis‚ as water softeners‚ commercial products such as shampoos and food preservatives‚ medicine‚ heavy metal detox‚ and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used

Nostre aetate begins by describing the unity of the origin of all people‚ and the fact that they all return to God; hence their final goal is also one. It describes the eternal questions which have boggled men since the beginning‚ and how the various religious traditions have tried to answer them. I have seen how It notes the willingness of the Catholic Church to accept other religions in so much as they lead souls to the Christ. I learned that it is not enough to stop learning about your culture

characterize the product of the reaction in favor of equilibrium. B. Results and Discussion: C. Experimental: 24 mL of 4-methylcyclohexanol‚ 5mL of phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer. A simple distillation set up was installed with a 250mL round bottom flask‚ jack‚ stirrer‚ heating mantle‚ and variac. The solution was heated gently with a small heating mantle to distill the crude product while keeping

SYNTHESIS SUMMARY Thesis: The GSAT examination should be addressed as an inadequate measure of scholastic ability and‚ hence‚ is unsuitable as the main tool used in the current academic system. Two recent articles have shed light on the public consensus showing displeasure with the GSAT examination. The first article‚ by Tyrone Reid GSAT ‘Unsuitable’ published in the Gleaner on Monday April 6‚ 2012‚ speculates at the appropriateness of the content of the exam and also its strict means

November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will then generate
