vaccines
COLUMBIA, Mo. !-- For years, researchers and physicians have known that infants' immune systems do not respond well to certain vaccines, thus the need for additional boosters as children develop. Now, in a new study from the University of Missouri, one researcher has found an explanation for that poor response.
Compound Found in Plant Products May Offer New Treatment for Malaria
In a new study researchers from France suggest that ellagic acid, a compound found in plant products, may be effective against malaria and ultimately lead to new forms of treatment. They report their findings in the March 2009 issue of the journal Antimicrobial Agents and Chemotherapy.
PITTSBURGH, March 19 - Researchers at the University of Pittsburgh School of Medicine have begun testing a vaccine that might be able to prevent colon cancer in people at high risk for developing the disease.
Do vaccines give Somalis autism? Can diabetes give you Alzheimer's? Does losing make you win? Anyone scanning the science news articles this week would know the answers to these questions.
A team of scientists at the Scripps Research Institute has found a way to use specially programmed chemicals to elicit an immediate immune response in laboratory animals against two types of cancer.
DURHAM, N.C. - An immune system response that is critical to the first stages of fighting off viruses and harmful bacteria comes from an entirely different direction than most scientists had thought, according to a finding by researchers at the Duke University Medical Center.
Distributed around the body, dendritic cells act as the security alarms of the immune system. After sensing the presence of intruders, dendritic cells can transmit the alarm to white blood cells or tell them to relax, depending on the signals they send out.
By studying how mice fight off infection by intestinal worms - a condition that affects more than 1 billion people worldwide - scientists have discovered that the immune system is more versatile than has long been thought.
For centuries, people have preserved fruit by mixing it with sugar, making thick jams that last for months without spoiling. Now scientists at the National Institute of Standards and Technology (NIST) have discovered* a fundamental property of mixture behavior that might help extend the life of many things including vaccines, food and library books -- and save money while doing it.
UAB (University of Alabama at Birmingham) researchers have developed a new, inexpensive and efficient method for producing and studying a type of human papillomavirus (HPV) that causes cervical cancer. The process could speed understanding of how the virus functions and causes diseases, and lead to new prevention or treatment options.
Scientists have identified a small family of lab-made proteins that neutralize a broad range of influenza A viruses, including the H5N1 avian virus, the 1918 pandemic influenza virus and seasonal H1N1 flu viruses.
New research suggests vaccines that specifically target HIV in the initial stages of infection before it becomes a rapidly replicating, system-wide infection - may be a successful approach in limiting the spread of the disease.
Scientists have begun to solve some of the mysteries of the common cold by putting together the pieces of the genetic codes for all the known strains of the human rhinovirus.
A study by a Montana State University researcher suggests a new avenue for developing a vaccine against genital herpes and other diseases caused by herpes simplex viruses.
According to the National Center for Health Statistics (NCHS), there were 11,647 new whooping cough cases diagnosed in 2003, which represents 4.0 cases per 100,000. Of these 11,647 cases, there were 18 deaths. The Centers for Disease Control (CDC) also reported that respiratory distress was among the Top Ten causes of mortality of children in 2002.
