Hundreds of children in about a dozen states have been sickened by a severe respiratory illness that public health officials suspect may be caused by an uncommon virus similar to the germ that causes the common cold. Nearly 500 children have been treated at one hospital alone—Children's Mercy in Kansas City—and some required intensive care, according to authorities.
The National Institutes of Health said it has uncovered a nearly century-old container of ricin and a handful of other forgotten samples of dangerous pathogens as it combs its laboratories for improperly stored hazardous materials. The agency began an intensive investigation of all its facilities after a scientist in July found vials of smallpox dating from the 1950s.
Key discoveries about breast cancer, Parkinson's disease and the body's handling of defective proteins have earned prestigious medical awards for five scientists. The Albert and Mary Lasker Foundation announced the winners Monday. Each prize includes a $250,000 honorarium. The awards will be presented Sept. 19 in New York.
Up to 30% of people with the most common form of hemophilia develop antibodies that attack lifesaving protein injections, making it difficult to prevent or treat excessive bleeding. Now researchers have developed a way to thwart production of these antibodies by using plant cells to teach the immune system to tolerate rather than attack the clotting factors.
Eli Lilly and Co. plans to seek approval early next year for a new insulin it developed after the diabetes treatment fared better than the competition in two late-stage clinical studies. The Indianapolis drugmaker said Thursday peglispro produced statistically significant lower blood sugar levels in patients when compared to people who took the Sanofi insulin Lantus in two late-stage studies of people with type 1 diabetes.
A self-assembling nanoparticle designed by a Univ. of Connecticut (UConn) professor is the key component of a potent new malaria vaccine that is showing promise in early tests. For years, scientists trying to develop a malaria vaccine have been stymied by the malaria parasite’s ability to transform itself and “hide” in the liver and red blood cells of an infected person to avoid detection by the immune system.
In a new study that could ultimately lead to many new medicines, scientists from the Florida campus of The Scripps Research Institute (TSRI) have adapted a chemical approach to turn diseased cells into unique manufacturing sites for molecules that can treat a form of muscular dystrophy.
Yale Cancer Center researchers may have discovered a new way of harnessing lupus antibodies to sabotage cancer cells made vulnerable by deficient DNA repair. The study found that cancer cells with deficient DNA repair mechanisms (or the inability to repair their own genetic damage) were significantly more vulnerable to attack by lupus antibodies.
Scientists have made an important breakthrough in the fight against debilitating autoimmune diseases such as multiple sclerosis by revealing how to stop cells attacking healthy body tissue. Rather than the body’s immune system destroying its own tissue by mistake, researchers at the Univ. of Bristol have discovered how cells convert from being aggressive to actually protecting against disease.
Removing both breasts to treat cancer affecting only one side doesn't boost survival chances for most women, compared with surgery that removes just the tumor, a large study suggests. The results raise concerns about riskier, potentially unnecessary operations that increasing numbers of women are choosing.
Responding rapidly to the deadly outbreak of Ebola virus disease (EVD) in West Africa, a team of researchers from the Broad Institute and Harvard Univ., working with the Sierra Leone Ministry of Health and Sanitation and researchers elsewhere, has sequenced and analyzed many Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests.
Some people take stress in stride; others are done in by it. New research at Rockefeller Univ. has identified the molecular mechanisms of this so-called stress gap in mice with very similar genetic backgrounds—a finding that could lead researchers to better understand the development of psychiatric disorders such as anxiety and depression.
Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye and looks under a microscope for the Plasmodium parasite, which causes the disease. This approach gives an accurate count of how many parasites are in the blood, but is not ideal because there is potential for human error.
An experimental Ebola drug healed all 18 monkeys infected with the deadly virus in a study, boosting hopes that the treatment might help fight the outbreak raging through West Africa. Scientists gave the drug, called ZMapp, three to five days after infecting the monkeys in the laboratory. Most were showing symptoms by then, and all completely recovered.
Sorry, clean freaks. No matter how well you scrub your home, it's covered in bacteria from your own body. And if you pack up and move, new research shows, you'll rapidly transfer your unique microbial fingerprint to the doorknobs, countertops and floors in your new house, too.
A unique method for delivering compounds that could positively impact the global battle against HIV and AIDS may be possible, thanks to researchers in Penn State's College of Agricultural Sciences. A semi-soft vaginal suppository made from the seaweed-derived food ingredient carrageenan and loaded with the antiviral drug Tenofovir provides a woman-initiated, drug delivery vehicle that can protect against the spread of STIs.
Federal researchers next week will start testing humans with an experimental vaccine to prevent the deadly Ebola virus. The National Institutes of Health announced Thursday that it is launching the safety trial on a vaccine developed by the agency's National Institute of Allergy and Infectious Diseases and GlaxoSmithKline.
Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria account for 80% of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.
Older adults losing vision as they age are more likely to face an increased mortality risk, according to new research from Purdue Univ. The researchers analyzed data from the Salisbury Eye Evaluation study that tracked the vision health of 2,520 older adults, ages 65 to 84. The research was funded by the National Eye Institute.
For the 2.2 million Americans battling glaucoma, the main course of action for staving off blindness involves weekly visits to eye specialists who monitor increasing pressure within the eye. Now researchers have developed an eye implant that could help stave off blindness caused by glaucoma. The tiny eye implant developed at Stanford Univ. could enable patients to take more frequent readings from the comfort of home.
Coffee contains antioxidants. Antioxidants fight gum disease. Researchers in dental medicine have found that coffee consumption does not have an adverse effect on periodontal health, and may have protective effects against periodontal disease.
A multidisciplinary team of scientists from the Univ. of California, Los Angeles and Stanford Univ. has used a naturally occurring nanoparticle called a vault to create a novel drug delivery system that could lead to advances in the treatment of cancer and HIV. Their findings could lead to cancer treatments that are more effective with smaller doses and to therapies that could potentially eradicate the HIV virus.
Princeton Univ. researchers have developed a way to use a laser to measure people's blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood.
As one of few Ebola survivors with medical expertise, Dr. Kent Brantly seems keenly aware of the position his painful experience has put him in. He hasn't spoken yet about his plans, but spent much of his first public appearance pleading for help for countries still struggling with the virus.
MDR-TB is a growing problem, estimated to kill 170,000 people annually and projected to infect more than two million people between 2011 and 2015. Janssen Research & Development LLC’s bedaquiline represents a significant scientific and public health advancement in the treatment of MDR-TB, as the first available medicine developed specifically for pulmonary MDR-TB treatment.
