A revolution in the monitoring of unborn babies

...t rates during pregnancy. While this technique has proven benefits, it needs to be administered by trained professionals and it is not suitable for routine, continuous, long-term monitoring. Dr Barrie Hayes-Gill and Dr John Crowe at The University of Nottingham recognised the need for a new technology that ...

Widely used hepatitis B drug spurs HIV drug resistance

A Johns Hopkins study has proven false established medical practice that an antiretroviral drug widely used to treat hepatitis B liver infections was safe to use on its own in patients co-infected with HIV. Their findings demonstrate that treatment with entecavir leads to cross-res...

Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal

...eatment of those with severe heart failure. It has proven greatly successful but is not without its shortcomings ?particularly the shortage of donor hearts and the risk of organ rejection. "This therapy has the potential to ease the pressure on the waiting list while also offering patients a better alte...

Men with prostate cancer avoid radiation due to misconceptions

...l beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery, according to a study presented November 5, 2006, at the American Society for Therapeutic Radiology and Oncology's 48th Annual Meeting in Philadelphia. ...

Genetically engineered blood protein can be used to split water into oxygen and hydrogen

...f the process. The resulting molecular complex was proven to be sensitive to light, and can capture light energy in a way that allows water molecules to be split into molecules of hydrogen and oxygen. Dr Stephen Curry, a structural biologist from Imperial College London's Division of Cell and Molecular Bi...

Researchers seek to design first treatment for neuroAIDS

...e drug's effect on neuroAIDs. CEP-1347 has already proven capable of reversing the neurotoxic effects of HIV proteins in living cells, according to research published in the July 1, 2006, edition of the Journal of Immunology. "We really don't know yet whether MLK or GSK-3b inhibitors will be superior to o...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...y carry visual signals to the brain; and they have proven to be functional. The photoreceptor precursors were transplanted into three different types of mice with retinal degeneration caused by distinct genetic defects involving malfunctioning or degenerating rods. The transplanted cells survived and w...

NYU biologists identify gene that coordinates two cellular processes

...ion has already been discovered. This approach has proven useful for learning about the roles of unknown genes. Unlike most genes in the network, mel-28 had connections to two distinct modules. Piano and Fernandez tested the idea that mel-28 plays important roles in both chromosome segregation and nucle...

Elusive rust resistance genes located

...rust resistant wheat varieties." The marker has proven effective in a range of wheats from different backgrounds including from Australia, India, China, North America and the major wheat research centre, CIMMYT. Breeders in Australia and across the world are now using the marker so that the durable r...

Natural protein stops deadly human brain cancer in mice

... and from the University of Milan have effectively proven that they can inhibit lethal human brain cancers in mice using a protein that selectively induces positive changes in the activity of cells that behave like cancer stem cells. The report is published this week in Nature. The most common type of brai...

Virus may control Australia's

... "It is anticipated that if these technologies are proven to be effective and safe, they will be applied on-ground in an integrated pest fish control program for the Murray-Darling Basin," Dr Crane says. Earlier outbreaks occurred in UK in 1996 but the first scientific reports appeared following the outbre...

Mayo researchers discover HIV dependence on a human protein

... of a crippled version of HIV itself, a virus with proven skill in accessing the human genome, to deliver the RNA interference. As a result, human T cells, HIV's main target, became resistant to HIV. Adding back p75 made them vulnerable again. And adding a "dominant-negative" piece of p75 to the mix, a sort...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...ontological evidence of these ancient microbes has proven elusive. At the AGU session, G. Todd Ventura of the University of Illinois-Chicago will describe what may be the earliest archaean fossil evidence yet discovered-rock samples that are 2.71 billion to 2.65 billion years old that were collected from a...

Knockout Mouse Project

...cientists will be working from the same tested and proven methodology. Eventually, the project may expand to include large scale studies related to the pathology of the 10,000 knock-out mouse strains. For now, scientists say there is much to be learned from the current study. ...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...e stimulating bone formation. "We have finally proven the theory that targeting one gene can do both," said Choi. "Now that we have demonstrated a new approach that is theoretically attainable, one that combines the best of both worlds, we can go to work on the genes up and down stream from our target g...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

...268." The triterpenoid CDDO-ME had already been proven effective in inhibiting proliferation and inducing apoptosis (programmed cellular death, a process that's often disrupted in cancer) in breast cancer cells, and blocked the growth of breast cancer cells in mice. CDDO and its synthetic variant CDDO-ME...
