Clinical trials are research studies monitoring medical procedures or medications, to evaluate its safety and efficacy. Each clinical trial is designed to answer specific scientific questions and to find new and better ways to help patients. For any illness or condition, a clinical trial may:
- Set the first effective treatment
- Establish a more effective treatment
- Establish a more lenient treatment
- Describe a new use for a treatment now available
An Overview of Typical Clinical Studies
A trial begins when a researcher identifies the drug to be tested, then decides which drugs compare, for example an existing treatment or a placebo. Then gather the participants, based on the eligibility criteria, and create and follow a protocol for a clinical trial. This protocol is based on the clinical study to be conducted.
Four Phases of Clinical Trials
There are four types of clinical trials: Phase I, Phase II, Phase III and Phase IV. Clinical studies of Phase I is the first phase of drug testing in humans. Typically, Phase I, involving healthy volunteers and requires several periods of stay in the hospital. The tests performed in Phase I typically test the safety, dosage and tolerance for certain drugs.
When the safety of the drug has been determined in the study of Phase I, Phase II studies are performed on larger groups of volunteers, this to test the efficacy and toxic drug d. The Phase III studies are performed in large groups of participants and multiple centers to conclude more about the effectiveness of a drug and to monitor for side effects. The Phase IV studies are testing trading after the sale of drugs to better show the benefits and risks.

Worlds Best Medical Care?
Many Americans are under the delusion that we have the best health care system in the world, as President Bush sees it, or provide the best medical care in the world, as Rudolph Giuliani declared last week. That may be true at many top medical centers. But the disturbing truth is that this country lags well behind other advanced nations in delivering timely and effective care
What happens when we die? (radio show)2007-08-28 10:35:45 by Jungledave
Here's a very interesting radio show about the near-death experience (NDE) with Sam Parnia, Fellow in Pulmonary & Critical Care Medicine at Cornell Medical Center in New York, and Senior Research Fellow at the School of Medicine at the University of Southampton in the UK.
To listen, click on one of the two tabs above the headline on this link page:
I know many NDErs personally, as I facilitate a group that studies and discusses NDE's. What most NDErs would like you to know is that there is no death and no reason to fear it, that you live forever, and that you are loved unconditionally - regardless of your beliefs (or non-beliefs)
Health insurance2009-11-14 15:57:39 by SeasonsChanging
And why is it that you don't have healthcare? If your job doesn't provide it, then buy it yourself! New York has programs for lower income folks, called Healthy New York, and it is a WONDERFUL program. Reduced premiums for private insurance.
And if you can't afford that, then go get Medicaid.
Studies and research have shown that a great majority of people in this country without medical insurance is by their own choice: They'd rather not pay a few hundred a month, and risk getting sick or in an accident---and then they'll piss and complain that they have no medical insurance

His early work (1946) was research on the influenza virus. In 1963, he became director of the Salk Institute for Biological Studies at the Univ. of California, San Diego. He developed a vaccine against poliomyelitis by cultivating three strains of the virus separately in monkey tissue. The virus was separated from the tissue, stored for a week, killed with formaldehyde, then tested to make certain that it is dead
