The compound, he found, proved effective in the laboratory and in animal studies, so Merck began tests in people, and it did exactly what it was supposed to — reduce levels of LDL cholesterol, the dangerous kind.
|
|
The researchers also found that the rats and mice absorbed radiation at different frequencies more easily depending on their body size — another good reminder that animal studies are a very poor way to understand human health.

The CAMARADES group also found that researchers conducting animal studies often don't take the simple steps to reduce bias: randomizing which animals get the placebo and which get the control, and being transparent about potential conflicts of interest.
|
|
The UK Food Standards Agency (FSA) said a substance called acrylamide, produced when starchy foods are roasted, fried or grilled for too long at high temperatures, has been found in animal studies to increase the risk of cancer.
|

But the researchers have found it wasn't as reversible in the larger animal studies, perhaps because the vas deferens is less "stretchy" to begin with, making it harder for the second injection to dissolve the polymer, Lissner said.
|

Corsello's team plans to conduct animal studies on some of the drugs to see which have the best chances of success in a clinical trial, and they plan to test even more cancer drugs for anti-cancer properties.

"Animal studies like this one contribute to our discussions on this topic, but we must remember the study was not designed to test the safety of cell phone use in humans, so we cannot draw conclusions about the risks of cell phone use from it," Shuren said.
|
|
As a result, we have had to rely on studies from other nations that had troops in Vietnam (South Korea and Australia), accidental exposures (for example, a 1976 accident in Seveso, Italy) and animal studies to essentially guess at what happened to exposed Americans and Vietnamese.

Robert Tarone, a biostatistician formerly with the U.S. National Cancer Institute and the International Epidemiology Institute, said the IARC's cancer finding was the result of a "flawed and incomplete summary of the experimental evidence" from animal studies, according to his May paper in the European Journal of Cancer Prevention.

After animal studies at Genentech yielded positive results, Dr. Shepherd and Dr. Ullrich teamed with Dr. Slamon to conduct clinical trials at U.C.L.A. They found that when they coupled the antibody with chemotherapy, the treatment stalled the progression of breast cancer associated with HER2 and extended survival longer than chemotherapy alone.
|
|
In a 2011 study on "sunscreen controversies," a team of doctors from Memorial Sloan-Kettering did a thorough review of previous research and found that the only data showing these ingredients were questionable came from animal studies, usually with extremely high doses — not studies in humans, or with doses typically used in humans.
|
|
One of the biggest problems with drawing conclusions from animal studies is that many of them involve very high doses — several orders of magnitude higher than anything humans are exposed to, explained Dr. Frederick Vom Saal, an endocrinologist and professor emeritus at the University of Missouri and one of the authors of the 2009 review.

Schriemer said they're planning to do some more animal studies and refine the way they cultivate these enzymes (they do this in the lab now, instead of growing hundreds of pitcher plants and collecting their juice the old-fashioned way), but is optimistic that this could join some other promising gluten intolerance treatments already in the pipeline.

"There's a stunning lack of transparency and accountability about how the government is spending our money in animal laboratories, and it's critical that taxpayers speak up, because it's clear that they can make a difference," he said, adding that the majority of drugs shown to be safe in animal studies end up failing in human clinical trials.
|
|
"They funded us to do some whole animal studies, similar to what NTP did but with a different premise, and they also funded us to do some other studies with cells, just isolated cells, and that included a study to look at DNA damage in response to exposure to two of their cell telephone signals," Phillips said.

If you look at the statement that we put out in my last week on the job when we talked about the seizure risk that we saw with the nicotine use, on the bottom half of that statement was a discussion around toxicology data that we had seen and some changes in animal studies consistent with precancerous changes in tissue from exposure to the vaping products.
