Researchers at the University of Alberta have shown that a nontoxic molecule shrinks cancers tumors, including lung, breast and brain. The results of the research will be published in the journal Cancer Cell.
The freeze-frame image of a molecular relay race, in which one enzyme passes off a protein like a baton to another enzyme, has solved a key mystery to how cells control some vital functions, according to investigators at St. Jude Children’s Research Hospital. A report on this work appears in the January 14 advanced online publication issue of Nature.
Brain tumors appear to arise from cancer stem cells (CSCs) that live within microscopic protective “niches” formed by blood vessels in the brain; and disrupting these niches is a promising strategy for eliminating the tumors and preventing them from re-growing, according to results of a study by investigators at St. Jude Children’s Research Hospital. CSCs are cells that continually multiply, acting as the source of tumors.
Louise Brown, the world’s first test tube baby, has given birth to a child of her own – a boy. 28-year-old Louise, an administrative assistant, and her husband Wesley Mullinder, 37, were delighted at the safe arrival of the baby.
A very high proportion of children who are having surgery are overweight or obese, and because of the excess weight have a greater chance of experiencing problems associated with the surgery, according to a new study from the University of Michigan Health System.
Uterus transplant could help many women fulfil the desire to have a child, as this is a tremendous driving force for many women, especially who cannot bear children because of a malfunctioning uterus. Doctors in a New York hospital are planning the first uterus transplant and are screening women who would have a chance to bear children.
A study at The University of Auckland is looking at the reasons behind New Zealand?s high rate of vasectomies.
A gene called SHANK3 is mutated in a small number of individuals with autism, providing new insight into the biological basis of this disease, according to a study to be published in the January issue of Nature Genetics.
Using cocaine during pregnancy can cause disabling cognitive impairments in kids. These impairments include attention deficits, learning disabilities and emotional problems. The study was conducted by researchers at the Vanderbilt Kennedy Center for Research on Human Development.
Surveyors of anti-aging elixirs tout human growth hormone as a remedy for all things sagging-from skin to libidos — and claim it can even prevent or reverse aging. But researchers at the Stanford University School of Medicine say there’s no evidence to suggest that this purported fountain of youth has any more effect than a trickle of tap water when it comes to fending off Father Time.
