A new study suggests that ovarian cancer cells form by hijacking a developmental genetic process normally used to form fallopian tubes. Scientists at the Georgia Institute of Technology and the Ovarian Cancer Institute discovered that the protein, PAX8, is involved in the development of fallopian tubes and is present in ovarian cancer cells, but not in normal ovarian tissue.
In experiments with laboratory mice that bearaggressive human breast cancers, UC Davis researchers have used hotnanoprobes to slow the growth of tumors — without damage to surroundinghealthy tissue. The researchers describe their work in the March issue ofthe Journal of Nuclear Medicine.
The response of tumors to anticancer drugs has been observed in real-time 3-D images using technology developed at Purdue University. The new digital holographic imaging system uses a laser and the same microchip used in household digital cameras, to see inside tumor cells. The device also may have applications in drug development and medical imaging.
UCLA researchers have uncovered new clues that may explain why Graves’ disease attacks the muscle tissue behind the eyes, often causing them to bulge painfully from their sockets, as in the case of the late actor Marty Feldman.
A treatment for polycystic kidney disease (PKD), a leading cause of fatal kidney failure worldwide, has been identified by a research team led by Yale biochemist Craig Crews, according to a report in the Proceedings of the National Academy of Sciences.
Inadequate intellectual stimulation and poor nutrition, especially iodine and iron deficiencies, are likely to blame for hindering more than 200 million children in developing countries from meeting their full potential, says a Purdue University researcher.
Genetic analysis has enabled the personalising of the pharmaceutical treatment of patients with cancer, enhancing thereby therapeutic efficacy and minimising possible toxicity.
Including more copper in your everyday diet could be good for your heart, according to scientists at the University of Louisville Medical Center and the USDA Human Nutrition Research Center.
A Deakin University study has unlocked one of the many mysteries of pregnancy — how the trace element copper is transported across the placenta. The findings provide a lead to the possible cause, treatment and prevention of a number of potentially fatal conditions.
Health Secretary Patricia Hewitt announced that the UK Government is accepting the 2007 pay review body recommendations for NHS staff and GPs. In line with the rest of the public sector, the implementation of awards over 1.5 per cent will be staged, with 1.5 per cent paid from 1 April and the remainder being paid from 1 November.
