Poplar trees redirect resources in response to simulated attack

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have applied some of the same techniques used in medical imaging to track the distribution of nutrients in poplar trees in response to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big he...

Genetically modified natural killer immune cells attack, kill leukemia cells

Natural killer (NK) immune system cells can be genetically modified to brandish a powerful "on-switch" that prompts them to aggressively attack and kill leukemic cells. This finding, from researchers at St. Jude Children's Research Hospital, suggests a way to improve the outcome of children who receive treatment for acute lymphoblastic leukemia (ALL) or other blood cancers. Results of the...

Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

A Medical College of Wisconsin research team, led by John W. Lough, Ph.D., professor of cell biology, neurobiology and anatomy has found that embryonic stem cells (ES cells) in animals can be cultivated to form new tissue, which eventually may help doctors learn how to replace tissue damaged as a result of a heart attack. The potential for ES cells to replace damaged or diseased cells in...

Genetic defects give the immune system the green light to attack the pancreas

Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas ?the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings published March 22 in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients. “The significance of...

One in Three Heart Attack Patients Have No Chest Pains

Death Rates Higher for Those Without This Symptom. As many as one-third of patients never have chest pains prior to or during a heart attack, a study published in The Journal of the American Medical Association suggests. And for women, diabetics and others who belong to groups likely to have atypical heart attack symptoms, more than half may never have such pains. The report examined symp...

White Cells Count Can Predict Heart Attack Death Risk

A simple blood test can give clue if the heart attack patients should get an immediate procedures to open clogged vessels and restore blood flow to their hearts. Cleveland Clinic cardiologist, Dr. Deepak Bhatt analyzed medical records of more than 12,000 heart disease patients and found that patients whose white blood cell count is in what is considered a "high normal range" have a mu...

New drug to treat Heart Attack and damaged tissue

If a blood vessel in blocked the related tissue experiences ischemia, a state of low oxygen supply that slowly kills the tissue. They are referred as Ichemia / Reperfusion (IR) injury occurs during heart attacks. Understanding Ischemia / Reperfusion leads to the development of new drugs to save the damaged tissue and treat heart attack. During Ischemia / Reperfusion, Early growth respons...

Early detection of heart attack

Researchers have found a new test to assess chest pain is accurate in more rapid diagnosis of a heart attack.Chest pain does not always signify a heart attack. It can be caused by indigestion or a panic attack. But the symptom is always treated as a medical emergency, and a series of tests is given to the patient to determine whether they have indeed suffered a heart attack.// These...
