Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

... with the vaccine will depend on the long-term and broad protection the vaccine can offer against cancer-causing HPV types. High Sustained Efficacy of a Prophylactic Quadrivalent Human Papillomavirus (HPV) (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine against Cervical Intraepithelial Ne...

Researchers from the UGR use a bacterium to obtain biopreservatives from food

...table with respect to pH and temperature and has a broad action spectrum against numerous bacteria, including pathogenic bacteria transmitted by food, "which makes it a suitable molecule to use as a biopreservative." The research carried out at the UGR will complete the information concerning the way th...

Illuminating the dark side of plants

...arden. The book contains vital information on a broad variety of poisonous and injurious temperate and tropical plants such as holly, poinsettia, and philodendron. It also includes common names, descriptions, species distribution, and information on the toxic part of each plant, and provides the latest...

Researchers first to map gene that regulates adult stem cell growth

...We think these findings will have an effect on the broad understanding of the molecular mechanisms that are important to stem cell regulation, including how some stem cells turn cancerous," Van Zant said. "The findings also will help scientists develop effective methods to modulate stem cell numbers and fu...

Scientists perform 'tricky' operation

...ification. Because of this, and also due to the broad and non-specific nature of symptoms, which can range from severe to negligible depending on the individual, some people pass it on without knowing. "Furthermore, the non-specific nature (or in some cases, absence) of trichomoniasis symptoms often ...

Will the plague pathogen become resistant to antibiotics?

...ility is present in other kinds of bacteria from a broad range of livestock, antibiotic resistance could potentially spread to other Y. pestis and also other bacterial pathogens. In a paper published March 21 in the new journal PLoS ONE, the authors say this possibility "represents a significant public hea...

NIH announces phase III clinical trial of creatine for Parkinson's disease

... Dr. Kieburtz. The study is designed to include a broad range of people, with special efforts to recruit a diverse population that is similar to the makeup of the population with PD in the United States. The investigators will measure disease progression using standard rating scales that measure qualit...

Recently discovered species gain protection

...ning in the early 20th Century and subsequently by broad scale deforestation for pasturelands. Only 370 acres of the bird's habitat previously had been in any way protected, but even this limited sanctuary is at risk from timber extraction clearing the last subtropical forest fragments surrounding it. No...

Hay fever can send work productivity down the drain

...e that family physicians would see patients with a broad spectrum of allergy symptoms. “Both kinds of physicians have access to thorough diagnostic tests, and can also prescribe heavy-duty allergy drugs, such as steroids that help block the body's natural reaction to allergens,?she continued. Participan...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

...t way to encourage doctors to make the switch from broad spectrum to narrow spectrum agents. They found that use of a pocket-sized laminated card telling doctors which antibiotics to prescribe combined with feedback on antibiotics use and CDI rates led to a significant drop in prescriptions of broad-spectr...

Scientists discover new species of distinctive cloud-forest rodent

...utiful yet strange looking, with long dense fur, a broad blocky head, and thickly furred tail. A blackish crest of fur on the crown, nape and shoulders add to its distinctive appearance. Isothrix barbarabrownae, as the new species has been named, is described in the current issue of Mastozoología Neotro...

Cancer cells forming blood vessels send their copper to the edge

...s of cellular copper this study revealed also have broad implications on the regulation of the metal ion content in metal-binding proteins. If such dramatic changes in where cellular copper is stored and used can happen so rapidly during angiogenesis, then the interactions of metal ions, such as copper, wi...

Research project tackles 'regeneration' gap

... "The fellows will be the glue that holds this broad group of scientists together," said Steindler, a professor of neuroscience at the UF College of Medicine. "We will begin a process of sharing ideas and designing experiments to answer questions about growth in simple systems that can then be applied ...

Microbes compete with animals for food by making it stink

...ll make ecologists think more critically about the broad role of microbes in the ecosystem. Microbes are often omitted or relegated to a minor role in food web diagrams, but they should be depicted as direct competitors with larger animals, he said. ...

Neuron cell stickiness may hold key to evolution of the human brain

...tudies that focused on genes have failed to find a broad pattern of human-specific evolution in brain genes. This led the Berkeley Lab researchers to suspect that the genetic basis of human-specific brain evolution might be found in the sequences that regulate genes, rather than the genes themselves. Ru...

Science researchers genetically transform immune cells into tumor fighters

...er should help highlight the significant work to a broad spectrum of people, including patients, clinicians and those involved in basic research," said Stephen Simpson, Science's senior editor, immunology. Rosenberg and colleagues have a long history of looking for ways to boost the body's natural immune...

Genome info from 'plant destroyers' could save trees, beans and chocolate

...ytophthora (pronounced "fy-TOFF-thor-uh") attack a broad range of plants and together cost the agriculture, forestry and nursery industries hundreds of billions of dollars each year. Even though Phytophthora are similar to fungi, most fungicides are ineffective at controlling them. The information gained ...

Comprehensive model is first to map protein folding at atomic level

...ein chains into tight three-dimensional shapes has broad implications for the growing number of disorders believed to result from misfolded proteins or parts of proteins, most notably neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. The model developed by Shakhnovich and colleag...

New drug blocks influenza, including bird flu virus

...ted the discovery of a novel compound that confers broad protection against influenza viruses, including deadly avian influenza. The new work, reported online this week (Oct. 4, 2006) in the Journal of Virology, describes the discovery of a peptide -- a small protein molecule -- that effectively blocks th...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...or his discovery has just been issued. "We see a broad application for this work," he explains. "We can build things that don't exist in nature. It's a versatile concept that doesn't apply to just one antimicrobial agent." Filutowicz and Burgess, wine enthusiasts who are as comfortable fermenting gra...
