Still Experimental

1 New Drug Kills Cancer Cells

Scientists have created a drug that kills cancer cells by choking off their sugar supply, causing them to consume themselves in a process called autophagy. The drug, created at Ohio State University and Richard J. Solove Research Institute, is part of a new class of anticancer drugs called energy-restriction mimetic agents and works by preventing cancer cells from metabolizing sugar, their source of energy. The new drug, dubbed OSU-CG12, is based on another used to treat diabetes but that also showed anticancer properties. "Energy restriction may offer a powerful new strategy for treating cancer because it targets a survival mechanism used by many types of cancer," says investigator Ching-Shih Chen who hopes to test the drug on other illnesses including Alzheimer’s and CV disease.

Simple Urine Test

2 First Diagnostic Test for Kidney Cancer Studied

Scientists at Washington University School of Medicine have identified two proteins, excreted into the urine, that could lead to early diagnosis and treatment of kidney cancer. Each year, about 50,000 patients are diagnosed with kidney cancer; more than 80 percent of them die within two years. Kidney cancer is curable however, when it’s diagnosed early. As of now, there is no diagnostic test for early detection. Most tumors are discovered incidentally during CT scans or ultrasounds that were ordered for other abdominal complaints. Further testing is needed to determine whether or not the proteins are good markers of kidney cancers but researchers are optimistic. The study will be published online in the May issue of Mayo Clinic Proceedings.

3 Near Death Experiences Due to High Levels of CO2?

Near death experiences, characterized by feelings of extreme calm, joy, and peace; the sensation of one’s life flashing before one’s eyes and encounters with guides or guardian angels who’ll lead one to the afterlife; may be explained by something as simple as raised levels of carbon dioxide in the blood, according to a report published in the journal Critical Care. The study, which investigated near death experiences, analyzed blood levels of 52 cardiac arrest patients and found that, of the 11 who said they had near death experiences, all of them had significantly higher blood carbon dioxide levels than those patients for whom the phenomenon didn’t happen. The study marks the first time carbon dioxide levels were linked to near death experiences. Researchers say further study is needed.
