Can two killers make a cure?

...est gene, lacZ, to the lungs of monkeys. After two months the gene was active in 21 per cent of cells, Kobinger told New Scientist. He is preparing the results for publication. "The gap between monkeys and humans is much smaller than from mice to monkeys," says Ray Pickles, a gene therapy researcher at the...

Shampoo detergent added to paint makes surfaces self-sterilizing

...crobes within seconds of application. Even after 5 months the coating could still self-sterilize within 30 seconds. "We found that the common shampoo ingredient cetavlon was especially effective, as well as having good dopant properties due to its being a detergent that mixes well with both aqueous and oil...

Hospitalizations because of chicken pox down dramatically since implementation of vaccine

After the yeast is gone bacteria continue to develop flavor of sparkling wine

...17 microbial strains from two Cavas, after 9 to 17 months of bottling. No yeasts were isolated after 10 months of bottling. Gram-negative and Gram-positive bacteria were isolated from both wines. Different phase...

Researchers develop gene therapy to reverse pulmonary arterial hypertension

...lds on previous work by the group, published a few months ago in Circulation Research, showing that an orally available drug, Dichloroacetate, selectively enhances apoptosis in PAH and thus reverses PAH, prolonging the survival of rats. Because this oral therapy has already been tried in humans with congeni...

Vaccine targets tumors where they live

...t remained alive without disease recurrence for 59 months after vaccination without any other therapy. This approach may be useful for altering the tumor environment in order to induce anti-tumor immunity and provides a foundation upon which other vaccine strategies can be contemplated for local delivery. ...

Genetic variation alters response to common anti-clotting drug

...nitial warfarin dose. However, it can take several months of clinic visits and needle pricks to determine an individual's ideal dose. Scientists know that variations in a gene encoding the CYP2C9 enzyme that metabolizes warfarin account for about 10 percent of the difference in people's responses to the dru...

NASA satellite data provides rapid analysis of Amazon deforestation

...bstantial reduction in effort in comparison to the months now required with Landsat," said Douglas Morton, scientist at the University of Maryland-College Park and lead author of the new study. Deforestation rates in tropical Africa, Southeast Asia, and South America have remained constant or have increase...

Experimental shingles vaccine proves effective in nationwide study

...e been." "For some people, shingles can result in months or even years of misery," comments study leader Mi...people with shingles experience pain lasting for 3 months or longer (the definition of PHN used in the study). As people age, however, shingles-associated ner...

Women feel more pain than men, research shows

... during and immediately after the programme, three months later women reported the same levels of pain as pre-treatment, whereas men's remained the same as immediately post-treatment. Interestingly, there were improvements in disability, in both sexes, which were maintained at follow-up. This suggested that...

Firefly protein lets researchers monitor molecule linked to cancer

...ca-Worms says. "Establishing that normally takes 6 months and 300 mice. With our monitoring technique, Shimon did it in a 5-day period using 30 mice. That's going to lead to tremendous cost savings." Because the luciferase-based monitoring system allows monitoring in live animals, Gross could perform multi...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...w, most mosquitoes become resistant in a matter of months rather than years. Worryingly, some resistant strains also show 'cross-resistance' to a number of different compounds, so spraying with one insecticide can unexpectedly increase resistance to newer compounds subsequently introduced to try and overco...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

... found no evidence that tumors had developed seven months after the cells were injected into multiple sites. While amniotic epithelial cells do not share the same capacity for unlimited replication as do embryonic stem cells, they still can double in population size about 20 times over without needing anot...

UW scientists report a new method to speed bird flu vaccine production

...t. The process is a race against time and can take months depending on how quickly new strains are identified, genetically disarmed and subsequently generated in the lab for use to make vaccines in large quantities. The new technique promises to ensure ready generation of seed strains for the production of ...

Updated data on novel HPV vaccine confirms efficacy in large population

...pre-cancers through follow up for an average of 20 months after completion of the regimen. HPV, particularly types 16 and 18, is the primary cause of cervical cancers and other related illnesses, infecting more than 20 million Americans. Globally, cervical cancer is among the leading cancers in women, wi...

Volunteers sought for avian flu vaccine study

... the bird flu or placebo vaccine over the next six months and will be required to provide blood samples to test if protection against the virus was produced. People 65 years or older who are interested in hearing more about the avian flu vaccine study, may call the Avian Influenza Hotline at 615-322-8740....

Research casts doubt on circulating stem cells

...t stem cell nuclei in the muscle fibre for several months after the bone marrow transplantation. And, as Professor Wernig emphasises, "they were found in numbers that would have had to bring a significant improvement to the condition of the muscle." The next step was to find out whether the stem cell nuclei...

Bone marrow stem cells may heal hearts even years after heart attacks

... cell infusions into the arteries of patients many months or years after a heart attack. The researchers harvested bone marrow from the hip bones of the patients, so there was no threat of transplant rejection. After processing, stem cells from the marrow were infused through a catheter into the coronary ar...
