significant health benefits, according to a new McMaster University
study that urges doctors not to cut umbilical cords immediately after
birth.
But waiting at least two minutes would allow precious red and white
blood cells to be transferred to the infant from the placenta before
it is expelled from the womb, says Hutton, whose study was published
yesterday in the Journal of the American Medical Association.
"We really haven't given a lot of consideration in the past to the
fact that there may be some value to the placenta (remaining
attached)," said Hutton, an epidemiologist and assistant dean of the
Hamilton school's midwifery program.

Molecular keys of saliva unlocked, allowing for bloodless diagnosis of
diseases: Study
Scientists have uncovered the molecular "alphabets" of saliva's key
protein and genetic components - work that will soon allow the early
detection of diseases ranging from lung cancer to osteoporosis through
the simple act of spitting into a vial, according to a study.
"Using these alphabets we can corner every human disease," says Dr.
David Wong, associate dean of research at California's UCLA School of
Dentistry. "The perception of saliva has now changed from a negative
connotation to a positive medical fluid."
Scientists have succeeded in cataloguing all 1,500 proteins, known as
the proteome, in healthy human saliva. It is accompanied by a complete
listing of saliva's 1.4 million bits of genetic information, known as
its genome.
