Scientists have uncovered details about how cancer is able to become drug resistant over time, a phenomenon that occurs because cancer cells within the same tumor aren’t identical.
A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of— and ahead of— its other antidepressant effects, in an NIH trial.
Researchers have found a way to kill prostate cancer cells by delivering a trove of copper along with a drug that selectively destroys the diseased cells brimming with the mineral, leaving non-cancer cells healthy.
A Dallas nurse being treated for Ebola has received a plasma transfusion from a doctor who beat his own infection with the deadly virus after getting a similar treatment. The reason: Antibodies in the blood of a survivor may help a patient fight off the germ.
Lethal fibrosis in lungs of mice with idiopathic pulmonary fibrosis (IPF) can be reversed, say researchers. No drug on the market can do this. But the crew pulled it off, in mice, by temporarily restoring (a mimic of) one of the body’s own anti-fibrosis agents, sharply reduced in IPF: microRNA-29.
Results of a small clinical trial suggest that a chemical derived from broccoli sprouts— and best known for claims that it can help prevent certain cancers— may ease classic behavioral symptoms in those with autism spectrum disorders (ASDs).
A research team has used high-resolution cryo-electron microscopy to obtain novel insights into the ultrastructural changes in an intracellular machine associated with the acquisition of resistance to the antibiotic erythromycin.
The first study of a possible Ebola vaccine is underway in Africa: University of Maryland researchers say three health care workers in Mali received the experimental shots.
An experimental drug saved the lives of 16 of 16 monkeys with the Marburg virus, a killer near-indistinguishable from Ebola, which caused the death of a Ugandan health worker Oct. 6.
Imagine being able to take a pill that lets you eat all of the ice cream, cookies, and cakes that you wanted– without gaining any weight. New research found a new way to suppress the obesity that accompanies a high-sugar diet, pinning it down to a key gene that pharmaceutical companies have already developed drugs to target.
Green tea has long been known for its anti-oxidant, anti-cancer, anti-aging and anti-microbial properties. Now, a group of researchers has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system.
Got grapes? UCLA researchers have demonstrated how resveratrol, an antioxidant derived from grapes and found in wine, works to inhibit growth of the bacteria that causes acne. The team also found that combining resveratrol with a common acne medication, benzoyl peroxide, may enhance the drug's ability to kill the bacteria and could translate into new treatments.
The use of broad-spectrum antibiotics by children before the age of 24 months was associated with increased risk of obesity in early childhood, according to a new study.
Striving to shine a light on potential ethical conflicts in medicine, the Obama administration is releasing data on drug company payments to tens of thousands of individual doctors.
Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.
Hope for healthier airways may be on the horizon thanks to a human airway muscle-on-a-chip that could be used to test new drugs because it accurately mimics the way smooth muscle contracts in the human airway, under normal circumstances and when exposed to asthma triggers.
Signaling the seriousness of the threat posed by antibiotic-resistant germs, President Barack Obama on Thursday ordered the government to create a national plan to fight them by early 2015.
A treatment regimen is safe and effective for restoring skin pigmentation in vitiligo patients, according to a new study. Patients were randomly divided into two study groups: Group A received a combination therapy; Group B received only NB UVB treatment.
An anti-addiction drug used to fight the nation's heroin and painkiller abuse epidemics poses a threat to young children who accidentally swallow relatives' prescriptions, a federal study says. Some children have died.
On this episode of Bioscience Technology This Week, Christina Jakubowski explores the role that bees may play in the search for antibiotic alternatives. Our second story focuses on how increased carbon dioxide levels in water can rob sharks of their ability to sense the smell of food.
One of the most rapidly fast-tracked vaccines in history— an anti-Ebola “ChAd3” vaccine— just started clinical trial in humans, and may be done as soon as November. But a second fast-tracked anti-Ebola vaccine— called an “rVSV” vaccine— is hot on its heels.
Mice treated with antibiotics to remove most of their intestinal bacteria or raised under sterile conditions have impaired antibody responses to seasonal influenza vaccination, researchers have found.
A research team is looking at whether an antibiotic has the potential to prevent or treat irregular heartbeats brought on by other medicines, thanks to a grant from national charity in the UK.
Taking benzodiazepines (widely prescribed drugs to treat anxiety and insomnia) is associated with an increased risk of developing Alzheimer's disease, particularly for long-term users, suggests a new study.
Working with mice, a multicenter team of researchers has found a new way to reduce the abnormal blood vessel growth and leakage in the eye that accompany some eye diseases.
