...OPRR is also investigating an experiment at the Bronx Veterans Affairs Medical Center, which is affiliated with the prestigious Mount Sinai Hospital in New York City. The study gave patients L-dopa, an amino acid that stimulates dopamine -- the brain's mood-regulating chemical messenger -- in order to observe psychotic breakdowns, allegedly without advising them on consent forms of the extreme discomfort and high risk of the undertaking. When Vera Hassner, an advocate for the mentally ill, complained to the project director, she received a letter that stated, "Patients may experience symptom aggravation . . . It would not be advisable to talk...
William Lane, director of the microchemistry facility in the Biological Laboratories at Harvard, identified the protein by comparing the sequencing of amino acids against a database...
...fact sheet issued by the campaign says that 31 deaths and more than 1500 serious illnesses "have been attributed to a genetically engineered amino acid called L-tryptophan." The Food and Drug Administration (FDA) failed to regulate the sale of the product because it was not labeled as "genetically engineered," the sheet charges...
...such a small mistake -- the equivalent of changing the spelling of Smith to Smyth -- have such an impact? Each three-letter "word" of a gene "sentence" spells out the instructions for producing 1 of 20 amino acids, compounds that in turn link to form proteins. A change in just one letter can result in the substitution of one amino acid for another. The new amino acid will be larger, smaller, stiffer or more elastic than the correct one. In ways radical and subtle, it will affect the shape of the protein and its activity. For if a cell is like...
