Damaged Heart Experiment

Men of science arrange Particles of Iron in Stem Cells and then applied Magnets to Guide Stem Cells To Damaged Heart.
"Stem cell therapies show great promise as a treatment for heart injuries, but 24 hours after infusion, we found that less than 10 percent of the stem cells remain in the injured area," said Eduardo Marbán, M.D., director of the Cedars-Sinai Heart Institute. "Once injected into a patient's artery, many stem cells are lost due to the combination of tissue blood flow, which can wash out stem cells, and cardiac contraction, which can squeeze out stem cells. We needed to find a way to guide more of the cells directly to the area of the heart that we want to heal."

Sicko by Michael Moore (full documentary)

I just found this documentary the other day on Google Video. The well known movie maker Michael Moore bends his attentions toward the matter of health care in the United States in this documentary film that counts the plight of the uninsured against the record-breaking profits of the pharmaceutical industry.

Potential Cancer Treatment Discovered

Late cancer breakthroughs indicate that cancer cells genetically reprogram their energy-generating pathways to produce the units they need to develop and multiply, consuming a lot of energy in the process. Potential drugs that immobilize this footpath could provide a new method to handle a range of cancers.

“All tumors have to deal with shifting metabolism as they proliferate,” says Vander Heiden, who joined the Koch Institute last fall. “If you can interfere with that, you have a chance to make a difference across many tumor types.”

Sugar is a source of energy for the human cells, it does not call for oxygen and produces much less energy.

In 2008, Vander Heiden, Cantley and other scientists at Harvard Medical School accounted in the journal Nature that once the cells switch between normal and Warburg metabolism, they start using PKM2 instead of pyruvate kinase M1, the enzyme that every full-grown cells use for glycolysis (the first set of reactions called for to break down glucose f…
