Biota makes major antiviral discovery

...the Biota RSV drug is expected to have significant advantages and could expand the market to include treatment as well as prevention and to other 'at risk' patient segments, such as children, the elderly and people with underlying respiratory conditions. Latest results in two animal models also demonstrate tha...

Metal-containing compounds show promise as HIV weapon

...HIV, preventing the proteases from working. Other advantages are that the compounds are stable and can be modified in many ways by attaching other strings of atoms to them. Further research may reveal that one modified version may be more stable or less toxic than another, for example.These compounds were also...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

...icates that these variants appear to have survival advantages over the wild, drug-sensitive strains. In addition, the infected birds die so rapidly there is no time for the virus to acquire a large number of mutations, among which could be changes in the M2 protein. Therefore, the high rate of M2 mutations in C...

Study provides insight into cellular defenses against genetic mutation

...hanges, or mutations, have no impact, some provide advantages making organisms more likely to survive, and others cause disease. One frequently occurring, damaging class of mutation is the inclusion of premature "stop reading" signals (stop codons) within mRNAs. Called "frameshift" or "nonsense" mutations, they...

'Smart' nanoprobes light up disease

...ble through an activateable probe with the imaging advantages provided by the brightness, photostability, and tunability of quantum dots." ...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

..., associate professor of genetics. One of the main advantages of this method is that it could potentially provide a long-term fix for a variety of genetic diseases, including muscular dystrophy. In muscular dystrophy, the muscle cells break down and are slowly replaced by fat. Eventually people with the diseas...

Penn Surgeons Use Completely Robotic Surgery to Successfully Treat Prostate Cancer

... Robotic technology offers a number of advantages during surgery. For instance, the robotic “arms?fi... Robotic technology also offers a number of advantages after surgery. Because laparoscopic surgery is minimally invasive and no large incisions are involve...

New battery technology helps stimulate nerves

...y the Wisconsin chemists, says West, have numerous advantages over traditional lithium battery chemistry. "They're very flexible. They don't solidify. They're stable, nonflammable, non-toxic and they pose no threat to the environment," says West, an international authority on silicon chemistry. Silicon, the st...

Sangamo BioSciences demonstrates its ZFP treatment protects cells from HIV infection

...ein on the surface of these cells may have several advantages over the systemic effects of other drugs in development." Small molecule or antibody approaches require the constant presence of antagonist in high enough concentrations to block therapeutically relevant numbers of the CCR5 protein, of which there a...

New brain scan technology could save babies' lives

...ms of oxygen supply and blood flow. Combining the advantages of MRI and ultrasound but avoiding their disadvantages, MONSTIR, the first scanner of its kind in the world, uses an innovative technique called optical tomography to generate images showing how the brain is working. In optical tomography, light pass...

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

...uld lead to inflammatory diseases. But we may find advantages to increasing Stat1 action in the short term using drug treatments." Such therapies could allow physicians to turn up the effect of interferon temporarily to treat infections or other disorders and then to turn it back down to normal levels when th...

Clawed frog helps Fanconi anemia research make leaps

...o repair DNA damage. Hoatlin said there are many advantages to using the frogs' eggs, instead of human cells, to study Fanconi anemia. "In human cells, most of the Fanconi proteins are hard to detect, so you have to grow millions of cells over long periods of time to collect enough to study," she said. "The...

New journal article urges use of animal serum-free media for growing live cells

...ne concerns, the article emphasizes the scientific advantages of serum-free cell culture. Growing cells without animal serum ensures that fewer variables are introduced into experiments, meaning that results are easily reproducible by different laboratories. ...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

...Label-free electronic detection of DNA has several advantages over state-of-the-art optical techniques, including cost, time, and simplicity. "Our technology can bring to market hand-held, field-ready devices for genetic screening, as opposed to laboratory methods using labor-intense labeling and sophisticated...

Human albumin from tobacco plants

... more productive in terms of biomass. Despite the advantages demonstrated by the experts, there is still a long way to go. Involving, as it does, a protein that is intravenously injected into patients, it has to be thoroughly purified to eliminate any kind of contaminant. Moreover, it is necessary to assure th...

Cheaper and simpler keyhole surgery

Endoscopic surgery brings many advantages for patients but is very difficult for the surgeon...is enabled 'solo surgery' and that it even brought advantages in comparison to surgery using an assistant. The second instrument developed by Jaspers is a mechan...

Faster immune system testing set to improve poultry quality

...ry worldwide, benefiting from production and price advantages as well as being viewed as healthy food. A particular attraction is the relatively short turn around ?five to eight weeks for broiler chickens. However production involves intensive housing and management to maximise output ?leading to an increase in...

Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

...polymersomes. "The system provides a number of advantages over other Trojan horse-style drug delivery system, and should prove a useful tool in fighting a number of diseases," said Dennis Discher, a professor in Penn's School of Engineering and Applied Science and a member of Penn's newly established Instit...

Data published in PNAS show antibodies can be made 10 times more toxic to cancer cells

...ces (PNAS). Monoclonal antibodies have important advantages over chemotherapy and small molecule drug treatments for cancer, such as their specificity in targeting tumor cells and low toxicity. There are currently eight approved anticancer antibody products on the market today and many more are in development...
