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.
In recent work, biology professor Kim Lewis and senior scientist Iris Keren demonstrate that all antibiotics are not created equal.
Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers have shown.
Scientists are reporting an advance in re-engineering photosynthesis to transform plants into bio-factories that manufacture high-value ingredients for medicines, fabrics, fuels and other products.
Biomedical engineering researchers have encapsulated two types of protein antigens in chitosan and demonstrated that the combined material enables or improves three important immune responses.
A panel of federal health experts says a long-established bone strengthening drug should no longer be used by women because there is little evidence it works and it may actually increase the risk of cancer.
Researchers have discovered how oxidative stress can turn to the dark side a cellular protein that’s usually benign, and make it become a powerful, unwanted accomplice in neuronal death. This finding could ultimately lead to new therapeutic approaches to many of the world’s debilitating or fatal diseases.
In a new study that tracked brain activity in human volunteers over a two-hour period as they lost and regained consciousness, researchers have identified distinctive brain patterns associated with different stages of general anesthesia.
Researchers have found that certain rare cells extracted from adult breast tissue can be instructed to become different types of cells– a discovery that could have important potential for regenerative medicine.
Scientists are reporting ‘laboratory resurrections’ of several 2-3-billion-year-old proteins that are ancient ancestors of the enzymes that enable today’s antibiotic-resistant bacteria to shrug off huge doses of penicillins, cephalosporins and other modern drugs.
Inspired by a chemical that fungi secrete to defend their territory, chemists have synthesized and tested several dozen compounds that may hold promise as potential cancer drugs.
A multi-institutional team has identified a molecular pathway that appears to be essential for the growth and spread of medulloblastoma, the most common malignant brain tumor in children.
There’s reassuring news for pregnant women miserable with morning sickness: A very large study in Denmark finds no evidence that using a popular anti-nausea drug will harm their babies.
As cancer researchers are learning more about the causes of glioblastoma tumor cell growth and drug resistance, they are discovering molecular pathways that might lead to new, targeted therapies to potentially treat this deadly cancer.
The overuse of antibiotics has created strains of bacteria resistant to medication, making the diseases they cause difficult to treat, or even deadly. Now, a research team has identified a weakness in at least one superbug that scientists may be able to medically exploit.
While studying a mutant strain of yeast, researchers may have found a new target for drugs to combat cholesterol and fungal diseases.
Previous studies found that smokers with COPD had the most significant decrease in one of the enzymes controlling chemical modifications to DNA, called HDAC2. Now, researchers showed that development of progenitor cells in the lung is specifically regulated by the combined function of two highly related HDACs, HDAC/1 and /2.
Popping calcium and vitamin D pills in hopes of strong bones? Healthy older women shouldn’t bother with relatively low-dose dietary supplements, say new recommendations from a government advisory group. Both nutrients are crucial for healthy bones.
A New Jersey jury has awarded $3.35 million to a former nurse who says Johnson & Johnson's vaginal mesh implant caused severe chronic pain despite 18 unsuccessful repair surgeries. It's the first verdict in about 4,000 lawsuits filed against the health products maker.
