A new global plan aims to end most cases of polio by late next year, and essentially eradicate the paralyzing disease by 2018— if authorities can raise the $5.5 billion needed to do the work, health officials said.
Using the same strategy that a common virus employs to evade the human immune system, researchers have modified adult stem cells to increase their survival– with the goal of giving the cells time to exert their natural healing abilities.
Researchers reported that three-dimensional scaffolds used to culture Ewing’s sarcoma cells were effective at mimicking the environment in which such tumors develop.
A team of scientists has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.
Researchers have investigated the effect that all seven botulinum toxins have on neuron survival, and they have discovered that not all botulinum toxins are equally safe for neurons.
Individuals who had taken a type of drug commonly used to treat Type 2 diabetes showed abnormalities in the pancreas, including cell proliferation, that may be associated with an increased risk of neuroendocrine tumors, according to a new study.
Two new studies shed light on the molecular biology of three blood disorders, leading to novel strategies to treat these diseases.
Until now most experimental vaccines against the highly lethal H5N1 avian influenza virus have lacked effectiveness. But a new vaccine has proven highly effective against the virus when tested in both mice and ferrets.
Have a heart problem? If it’s fixable, there’s a good chance it can be done without surgery, using tiny tools and devices that are pushed through tubes into blood vessels.
A team of scientists has determined and analyzed the high-resolution atomic structures of two kinds of human serotonin receptor.
Inflammation is stirring up headlines again. Anti-inflammatory aspirin prevented thousands more cancers. The anti-inflammatory “miracle molecule” resveratrol came back. Psychologists report inflammation is stoked by even minor tensions. And archaeologists say all this knowledge is long overdue, as even Egyptian mummies have clogged arteries. We have been plagued by inflammation since the time of the Pharaohs.
Research has uncovered a method to produce retinal cells from regenerative human stem cells without the use of animal products, proteins or other foreign substances.
Don't look for testing of the anthrax vaccine to begin in children any time soon. Controversy arose last year as experts debated whether such studies should be done to learn how to treat children in case of a bioterror attack.
In a small, preliminary study of regular migraine sufferers, scientists have found that measuring a fat-derived protein called adiponectin (ADP) before and after migraine treatment can accurately reveal which headache victims felt pain relief.
Researchers at Albert Einstein College of Medicine of Yeshiva University and the Icahn School of Medicine at Mount Sinai have found that macrophages – white blood cells that play a key role in the immune response– also help to both produce and eliminate the body’s red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance. The study, conducted in mice, is published today in the online edition of the journal Nature Medicine.
Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find.
Researchers report that influenza virus-specific CD8+ T cells or virus-specific non-neutralizing antibodies are each relatively ineffective at conferring protective immunity alone. But, when combined, the virus-specific CD8 T cells and non-neutralizing antibodies cooperatively elicit robust protective immunity.
Autism results from abnormal cell communication. Testing a new theory, researchers have used a newly discovered function of an old drug to restore cell communications in a mouse model of autism, reversing symptoms of the devastating disorder.
A team of neuroradiologists and neurosurgeons reported wide success with a new procedure to treat pseudotumor cerebri, a rare but potentially blinding condition marked by excessive pressure inside the skull, caused by a dangerous narrowing of a vein located at the base of the brain.
A seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers to the discovery of an atypical protein that lures, traps and inactivates the powerful Polo kinase, widely considered the master regulator of cell division.
Engineers have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs.
The Food and Drug Administration has approved a new imaging drug, Lymphoseek, from Navidea Biopharmaceuticals Inc., to help doctors locate lymph nodes in patients with breast cancer and skin cancer.
The Food and Drug Administration is warning doctors and patients that a widely used antibiotic from Pfizer can cause rare but deadly heart rhythms in some patients. The agency said Tuesday that it is adding new warnings to the label of Zithromax, which is commonly used to treat bronchitis, pneumonia and other infections.
Modern medicine is largely based on treating patients with “small-molecule” drugs, which include pain relievers like aspirin and antibiotics such as penicillin. Those drugs have prolonged the human lifespan and made many life-threatening ailments treatable, but scientists believe the new approach of nanoscale drug delivery can offer even more progress.
