vaccines
STANFORD, Calif. - Public speaking, anyone? Or maybe a big job interview? Dry your palms and take a deep, calming breath; there may be a silver lining. Researchers at the Stanford University School of Medicine have shown that, at least in laboratory mice, bouts of relatively short-term stress can boost the immune system and protect against one type of cancer.
Early results from a trial testing a 2009 H1N1 influenza vaccine in children look promising, according to the trial sponsor, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
BEER-SHEVA, September, 21 2009 -- A researcher who is working on a vaccine for Alzheimer's disease (AD) has demonstrated that it is possible to test and measure specific immune responses in mice carrying human genes and to anticipate the immune response in Alzheimer's patients.
CORVALLIS, Ore. -- Scientists at Oregon State University have developed a new "adjuvant" that could allow the creation of important new vaccines, possibly become a universal vaccine carrier and help medical experts tackle many diseases more effectively.
ANN ARBOR, Mich. -- Treating second-degree burns with a nanoemulsion lotion sharply curbs bacterial growth and reduces inflammation that otherwise can jeopardize recovery, University of Michigan scientists have shown in initial laboratory studies.
FINDINGS: Some budding yeast species have the ability to silence genes using RNA interference (RNAi). Until now, most researchers thought that no budding yeasts possess the RNAi pathway because Saccharomyces cerevisiae, the protoypical model budding yeast does not.
As manufacturers work furiously to make a vaccine to protect against 2009 influenza A (H1N1) virus, a Rice University bioengineer is trying to improve the process for future flu seasons. The goal is to shorten the time it takes to identify targeted flu strains and manufacture the vaccines for them.
A new vaccine against pneumonia may offer better protection from chronic obstructive pulmonary disease (COPD) patients than the currently accepted vaccine, according to recent research that will be published in the September 15 issue of the American Journal of the Respiratory and Critical Care Journal, a publication of the American Thoracic Society.
Researchers in Australia are developing diversionary tactics to fool disease-causing bacteria in the gut. Many bacteria, including those responsible for major gut infections, such as cholera, produce toxins that damage human tissues when they bind to complex sugar receptors displayed on the surface of cells in the host's intestine.
(SALT LAKE CITY) -- In a finding with potentially major implications for identifying a viral cause of prostate cancer, researchers at the University of Utah and Columbia University medical schools have reported that a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in malignant human prostate cancer cells.
By adapting a single protein on the surface of the bacterium Caulobacter crescentus, researchers at the University of British Columbia have turned it into a protein production factory, making useful proteins that can act as vaccines and drugs. Dr.
Killed or disabled viruses have proven safe and effective for vaccinating billions worldwide against smallpox, polio, measles, influenza and many other diseases.
But killed or severely "attenuated" vaccines, which are safer than "live" vaccines, have been largely unsuccessful for many non-viral diseases, including illnesses like tuberculosis and malaria.
Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. By influencing early social experience in prairie voles, researchers hope to gain greater insight into what aspects of early social experience drive diversity in adult social behavior.
An analysis published August 25 in the open-access journal PLoS Neglected Tropical Diseases sheds new light on the toll that neglected tropical diseases (NTDs) take on sub-Saharan Africa (SSA), with an estimated 500 million people suffering from these debilitating and sometimes deadly diseases. Helminth infections account for approximately 85% of the NTD burden.
BOSTON--Two of the most powerful approaches to cancer treatment -- a stem cell transplant and an immune system-stimulating vaccine -- appear to reinforce each other in patients with an aggressive, hard-to-control form of leukemia, Dana-Farber Cancer Institute scientists have found.
