In fact, some believe that Internet surveying and electronic data collection may revolutionize many disciplines by allowing for easier data collection, larger samples, and therefore more representative data. However, others are skeptical of its usability as well as its practical value. The paper highlights both positive and negative outcomes experienced in a number of e-research projects, focusing on several common mistakes and difficulties experienced by the authors. The discussion focuses on ethics and review board issues, recruitment and sampling techniques, technological issues and errors, and data collection, cleaning, and analysis.
Modified and Additional Material by Arthur M. Alex Constantine and Gregory Gordon Posted: Searle and Company Farberpage A group working on an ulcer drug was formed including Dr. In particular, they were looking for an inhibitor of the gastrointestinal secretory hormone gastrin Stegink a.
In December ofwhile James Schlatter was recrystalling aspartame from ethanol, the mixture spilled onto the outside of the flask. Some of the powder got onto his fingers. Later, when he licked his fingers to pick up a piece of paper, he noticed a very strong sweet taste.
He realized that the sweet taste might have been the aspartame. So, believing that the dipeptide aspartame was not likely to be toxic, he tasted a little bit and discovered its sweet taste Stegink a, page 4. The discovery was reported inbut there was no mention of the sweetness Furia Preliminary tasting showed this compound to have a potency of times sucrose depending on concentration and on what other flavors are present and to be devoid of unpleasant aftertaste.
So, what is aspartame, a. Aspartame C14H18N2O5 is a compound of three components. These components are methanol, aspartic acid and phenylalanine the latter being free form amino acids. Methanol methyl alcohol or wood alcohol is a colorless, poisonous, and flammable liquid.
This poison can be inhaled from vapors, absorbed through the skin, and ingested. Methanol is the type of alcohol you read about when people become blind from drinking it. This occurs in even small amounts, and is especially damaging when introduced with toxic, free-form amino acids, called excitotoxins.
Methanol is quickly absorbed through the stomach and small intestine mucosa.
The methanol is converted into formaldehyde a known carcinogen. Then, via aldehyde hydrogenase, the formaldehyde is converted to formic acid. These two metabolites of methanol are toxic and cumulative. Phenylalanine is an amino acid. Well, amino acids are good for us, right?
The answer is yes, amino acids are necessary for good health, EXCEPT when you separate the individual amino acid from its protein chain, and use it as an "isolate" or by itself.
The Aspartic acid, in aspartame, is also an excitotoxin. An excitotoxin, is a deleterious substance that excites or over-stimulates nerve cells. This pathological excitation of nerve cells creates a breakdown of nerve function, as we will see.
Basically, they are a group of compounds that can cause special neurons within the nervous system to become overexcited to the point that these cells will die.
Excitotoxins include such things as monosodium glutamate MSGaspartate, a main ingredient in NutraSweetL-cysteine found in hydrolyzed vegetable protein and related compounds.
It appears that an imbalance of these excitotoxins during critical periods of brain development can result in an abnormal formation of brain pathways; that is, a "miswiring of the brain.
One of the earliest observations seen in animals exposed to large doses was gross obesity. Aspartame creates altered brain function, nerve damage, and systemic organ complications.
See list of symptoms 1 Aspartame is a toxin, and is unique in this hazardous respect. This in NOT an allergic reaction, but rather a true toxin.
No other food can be provided as a comparison to the toxic nature of NutraSweet. Upon closer examination, the available research revealed that the manufacturer Monsanto and the FDA are manipulating the public via the media into thinking that aspartame is safe.
As an American who trusted the system we all created, as an American who worked for the system, it made me angry that public health has taken a backseat to greed. This is the "engine" that perpetuated this epidemic: Memorial Laboratory of Mental Retardation Research and a respected expert in phenylalanine toxicity, to conduct a study of the effects of aspartame on primates.
The study was initiated on January 15, and was terminated on or about April 25, Waisman died unexpectedly in March, Seven infant monkeys were given aspartame with milk.
One died after days.§ Implementation of Texas Essential Knowledge and Skills for Agriculture, Food, and Natural Resources, Adopted (a) The provisions of this subchapter shall be implemented by school districts beginning with the school year.
Animal testing regulations are laws or guidelines that permit and control the use of non-human animals for scientific pfmlures.com vary greatly around the world, but most governments aim to control the number of times individual animals may be used; the overall numbers used; and the degree of pain that may be inflicted without anesthetic.
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals in experiments that seek to control the variables that affect the behavior or biological system under study.
Research ethics provides guidelines for the responsible conduct of biomedical research. In addition, research ethics educates and monitors scientists conducting torturous “experiments” with concentration camp inmates. The accused physicians tortured, brutalized, Research must be based on sound theory and prior animal testing 4.
Ethics Of Animal Testing This theme song to a popular cartoon is a farce dealing with experiments carried out on animals. In the cartoon one mouse is made very smart and wants to take over the world while the other is clearly not as smart. While the cartoon makes jokes, the reality is that. The ethics of research involving animals.
Nuffield Council on Bioethics Professor Sir Bob Hepple QC, FBA of violent action against those conducting animal research in the UK have brought the matter to avoiding the polarisation of views which has so often stifled proper debate.
It is in this spirit that.
