| Nanowire array detects cancer by identifying molecular markers - Sep 27, 2005 22:28 IST |
|
Harvard University researchers, Professor Charles Lieber and his students have made wires whose thinness is measured in atoms instead of fractions of an inch. This allowed Lieber’s team to develop a coated wire array capable of detecting low levels of a protein that marks the presence or recurrence of prostate cancer. These silicon nanowires have such exceptional accuracy and sensitivity that they can detect these cancer markers even when they constitute only one hundred-billionth of the protein present in a drop of blood. In addition these minuscule devices also promise to pinpoint the exact type of cancer present with a speed not currently available to clinicians.

| Face Transplant – ray of hope for a better life or a journey through identity crisis - Sep 20, 2005 8:0 IST |
|
|
After years of research and an year long discussion on face transplant, the Cleveland Clinic has finally been able to win approval to perform the intense 10 hour long operation from an internal review board comprising of surgeons, psychiatrists, social workers, therapists, nurses and patient advocates. This would be for the first time that a face transplant would be performed. The panel of doctors, headed by Dr. Maria Siemionow, who have the task of performing the operation plans to interview 12 people with severely disfigured faces before going ahead with the operation. The interview aims at getting acquainted with the mental state of the potential candidates, five men and seven women, as to whether they are psychologically strong enough to adapt to the new face. Also, since the face transplant would require the patient to take anti-rejection and immuno suppressant drugs which could have long term side effects such as kidney damage and cancer, doctors need to select a patient who is physically strong as well.

| Life Saver Poses a Threat to Life - Sep 18, 2005 7:56 IST |

Implanted cardioverter defibrillators, or ICDs, and pacemakers that shock an irregularly beating heart into normal rhythm were "directly responsible" for 61 deaths out of nearly 3 million implants between 1990 and 2002, according to a report from the Food and Drug Administration released on Friday. The report also revealed that 4,225 defibrillators had failed between 2000 and 2003, about as many as those that failed in the previous 10 years. It is believed as the design of defibrillators is becoming more sophisticated, rate of failure is also rising.

Olive Oil has an anti-inflammatory action similar to the popular painkiller ibuprefen, a recent study says. A compound found in olive oil called oleocanthal, inhibits COX enzymes in the same dose-dependent manner as ibuprofen, a member of the nonsteroidal anti-inflammatory class of drugs, write Paul A. S. Breslin from the Monell Chemical Senses Center in Philadelphia and colleagues in the 31 August issue of Nature.
