Old compound, new use

Old compound, new use
The compound, α-difluoromethylornithine or DFMO, targets the activity of a specific enzyme and, even in very limited doses, is effective in protecting against the malignancy in animal models. The study was reported in the January 15, 2009 issue of the journal, Cancer Research (Volume 69, Issue 2). "The drug, which was developed as a cancer treatment and later shelved because of toxicity concerns, has been around since the 1970s,"........Go to the Cancer-blog (Added on 1/15/2009 6:41:26 PM)


Breakthrough in Treating Premature Babies

Breakthrough in Treating Premature Babies
Adelaide scientists have made a world breakthrough in treating premature babies at risk of developmental disorders. A six-year study led by Dr Maria Makrides from the Women's & Children's Health Research Institute and Professor Bob Gibson from the University of Adelaide has demonstrated that high doses of fatty acids administered to pre-term infants via their mother's breast milk or infant formula can help their mental development.

Alzheimer's research based on family consent

Alzheimer's research based on family consent
By the time they have been diagnosed with Alzheimer's disease, a number of patients' decision-making ability is so impaired that they cannot give informed consent to participate in research studies. Close family members are left with the decision, but there is no clear policy for this so-called "surrogate" consent. Because of that, research about the increasingly common disease is often stalled. But a newly released study led by the........Go to the Neurology news blog (Added on 1/14/2009 11:34:54 PM)

A new protein that initiates breast cancer
Canadian scientists have identified a novel protein in the advancement of breast cancer. As per a recent study from the Universit de Montral and the University of Alberta, reported in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours. Targeting this protein with drug treatment may provide hope to women with breast cancer.

Where am I?
We've all experienced the feeling of not knowing where we are. Being disoriented is not pleasant, and it can even be scary, but luckily for most of us, this sensation is temporary.

New evidence for warburg theory of cancer
German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive.
