Parallel track

Proceeding along a parallel track, Guillory and coworkers used DTA analysis to study complexation phenomena [2]. Through the performance of carefully designed studies, they were able to prove the existence of association complexes and deduced the stoichiometries of these. In this particular work, phase diagrams were developed for 2 1 deoxycholic acid-menadione, 1 1 quinine-phenobarbital, 2 1 theophylline-phenobarbital, 1 1 caffeine-phenobar-bital, and 1 1 atropine-phenobarbital. The method was also used to prove that no complexes were formed between phenobarbital and aspirin, phenacetin, diphenylhydantoin, and acetaminophen.

Train A leaves the station heading due east at 12 00 P.M. at a constant rate of speed of 40 miles per hour. Train B leaves the same station, also heading due east at 1 00 P.M., at a constant rate of 50 miles per hour on a parallel track. When will train B meet train A ... 

Two trains are 440 miles apart, traveling toward each other from opposite directions on parallel tracks that are next to each other. Train A is traveling north at 60 miles per hour and Train B is traveling south at 50 miles per hour. How long will it take before they pass each other ... 

Two trains are 780 miles apart and are traveling toward each other on parallel tracks. One is heading east at 75 miles per hour the other is heading west at 55 miles per hour. How long until the trains meet ... 

Parallel Track Some patients do not fulfill the criteria to be enrolled in clinical trials, but their conditions quahfy them to be treated in parallel with an ongoing chnical trial. AIDS patients are an example for this group. 

Parallel Track is another mechanism that permits dispensing investigational drugs, particularly to AIDS patients that do not qualify to participate in controlled clinical trials of promising drug candidates. The parallel track policy was developed by the US Public Health Service in response to the AIDS epidemic. Federal Register of 21 May 1990)... 

The current route for drug development is outlined in Figure 1 and can be found on the web at http //www.FDA.gov/cder/handbook. In 1988-89 regulations were loosened with respect to drugs proposed for the treatment of AIDS-related illnesses so that new drugs could be prescribed before all of the extensive testing was finished. This is referred to as the "fast" or "parallel track". 

Very ill patients may receive a drug that shows promise in late clinical trials. This requires the IND to be classified as a treatment IND. Treatment IND status is valuable for critically ill patients who may not be able to wait until the drug receives full NDA approval. Related to a treatment IND is the parallel track policy. Specifically developed to help AIDS patients, INDs with parallel track classification may be administered to patients who are not healthy enough to qualify for inclusion in a phase trial. Data from parallel track patients are not included in the clinical trial data. 

Parallel track Mechanism to provide patients with AIDS or related diseases early access to experimental therapies. 

Parallel Track Mechanism A U.S. Public Health Service policy that makes promising investigational drugs for AIDS and other HIV-related diseases more widely available under parallel track protocols while the controlled clinical trials essential to establish the safety and effectiveness of new drugs are carried out. The system established by this policy is designed to make drugs more widely available to patients with these illnesses who have no therapeutic alternatives and who cannot participate in the controlled clinical trials. 

The reflex doctrine could not, however, help the pioneer sleep and dream scientists very much, because no link could be established between the activity of circuits of neurons (neuronal circuits) and the EEG. It had long been assumed that the EEG was the register of voltage changes in the brain (i.e. cerebral action potentials), although this could not explain the patterns of the EEG seen in sleep (e.g. spindles and slow waves), unless neuronal activity was continuous, i.e. spontaneous, as well as reflexive. Consequently, work at the cellular and EEG levels proceeded along entirely separate but parallel tracks, similar to those that Descartes thought God had used to set mind and body in perfect but independent motion. Cartesian duality dies slowly it is still alive and well in most of us because we cannot yet see how a physical object, the brain, can have subjective experience. This is the so-called hard problem of philosophy. 

A train leaves a station traveling west at 60 mph. At the same time, another train heads east on a parallel track, traveHng at a rate of 70 mph. If the 2 trains are initially 700 miles apart, how far apart are they after 1 hour ... 

A desirable parallel track would be the compilation of a directory of compounds already identified from the Antarctic with details of their known toxic effects. Equally desirable, but, with existing biological knowledge, much more difficult to achieve, is the identification of indicator organisms (for terrestrial, freshwater and marine systems) whose health can be taken to represent that of the entire community or ecosystem.
