A chemical found in garlic can kill bacteria that cause life-threatening lung infections in people with cystic fibrosis, research suggests. The study is the first to show that the chemical, known as allicin, could be an effective treatment against a group of infectious bacteria that is highly resistant to most antibiotics.
Oxytocin, sometimes referred to as the “love” or “cuddle” hormone, has a legendary status in...
Drinking red grape juice or wine in moderation could improve the health of overweight people by...
The health-promoting perks of wine have attracted the spotlight recently, leaving beer in the shadows. But scientists are discovering new ways in which the latter could be a more healthful beverage than once thought. They’re now reporting that a compound from hops could protect brain cells from damage, and potentially slow the development of disorders such as Alzheimer’s and Parkinson’s diseases.
As predators go, cone snails are slow moving and lack the typical fighting parts. They’ve made up for it by producing a vast array of fast-acting toxins that target the nervous systems of prey. A new study reveals that some cone snails add a weaponized form of insulin to the venom cocktail they use to disable fish.
New research has identified one of the key cancer-fighting mechanisms for sulforaphane, and suggests that this phytochemical may be able to move beyond cancer prevention and toward therapeutic use for advanced prostate cancer. Scientists said that pharmacologic doses in the form of supplements would be needed for actual therapies, beyond the amount of sulforaphane that would ordinarily be obtained from dietary sources such as broccoli.
Mistletoe hanging in doorways announces that the holidays are just around the corner. For some people, however, the symbolic plant might one day represent more than a kiss at Christmas time: It may mean better liver health. Researchers have found that a compound produced by a particular variety of the plant can help fight obesity-related liver disease in mice.
Take two poisonous mushrooms, and call me in the morning. While no doctor would ever write this prescription, toxic fungi may hold the secrets to tackling deadly diseases. A team of Michigan State Univ. scientists has discovered an enzyme that is the key to the lethal potency of poisonous mushrooms.
Researchers at the Univ. of Georgia have discovered that a chemical compound commonly found in coffee may help prevent some of the damaging effects of obesity. In a recently published paper published, scientists found that chlorogenic acid, or CGA, significantly reduced insulin resistance and accumulation of fat in the livers of mice who were fed a high-fat diet.
The health benefits of over-the-counter curcumin supplements might not get past your gut, but new research shows that a modified formulation of the spice releases its anti-inflammatory goodness throughout the body.
Self-injury is one of the most difficult behaviors associated with autism and other developmental or intellectual disabilities, and a private facility outside Boston that takes on some of the hardest-to-treat cases is embroiled in a major debate: Should it use electrical skin shocks to try to keep patients from harming themselves or others?
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.
Veterans, medical marijuana activists and scientists welcomed the first federally approved research into pot as a treatment for post-traumatic stress disorder. But their hopes for the research were dashed when the Univ. of Arizona fired researcher Suzanne Sisley, who undertook the study after clearing four years of bureaucratic hurdles.
For anyone searching for another reason to enjoy a glass of red wine with dinner, here’s a good one: A new study has found that red wine, as well as grape seed extract, could potentially help prevent cavities. They say that their report, which appears in the Journal of Agricultural and Food Chemistry, could lead to the development of natural products that ward off dental diseases with fewer side effects.
Patients who use medical marijuana for pain and other chronic symptoms can take an unwanted hit: Insurers don't cover the treatment, which costs as much as $1,000 a month. Once the drug of choice for hippies and rebellious teens, marijuana in recent years has gained more mainstream acceptance for its ability to boost appetite, dull pain and reduce seizures in everyone from epilepsy to cancer patients.
For HIV patients being treated with anti-AIDS medications, resistance to drug therapy regimens is commonplace. Often, patients develop resistance to first-line drug therapies, such as Tenofovir, and are forced to adopt more potent medications. Virologists at the Univ. of Missouri now are testing the next generation of medications that stop HIV from spreading, and are using a molecule related to flavor enhancers found in soy sauce.
What's good for the heart? Marriage, researchers say. A study of more than 3.5 million Americans finds that married people are less likely than singles, divorced or widowed folks to suffer any type of heart or blood vessel problem. This was true at any age, for women as well as for men, and regardless of other heart disease risk factors they had such as high cholesterol or diabetes.
The federal government has signed off on a long-delayed study looking at marijuana as a treatment for veterans with post-traumatic stress disorder, a development that drug researchers are hailing as a major shift in U.S. policy. The Dept. of Health and Human Services' decision surprised marijuana advocates who have struggled for decades to secure federal approval for research into the drug's medical uses.
It won't be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes. The pills are so packed with nutrients that you'd have to eat a gazillion candy bars to get the amount being tested in this study, which will enroll 18,000 men and women nationwide.
Women with estrogen-responsive breast cancer who consume soy protein supplements containing isoflavones to alleviate the side effects of menopause may be accelerating progression of their cancer, changing it from a treatable subtype to a more aggressive, less treatable form of the disease, new research suggests.
Rice Univ. scientists have created a way to fine tune a process critical to the pharmaceutical industry that could save a lot of time and money. A combination of the Rice technique that provides pinpoint locations for single proteins and a theory that describes those proteins’ interactions with other molecules could widen a bottleneck in the manufacture of drugs by making the process of isolating proteins five times more efficient.
Exposing skin to sunlight may help to reduce blood pressure and, thus, cut the risk of heart attack and stroke, a recently published study suggests. Research carried out at the Univs. of Southampton and Edinburgh shows that sunlight alters levels of the small messenger molecule, nitric oxide (NO) in the skin and blood, reducing blood pressure.
Whether it's a mug full of fresh-brewed coffee, a cup of hot tea or a can of soda, consuming caffeine is the energy boost of choice for millions who want to wake up or stay up. Now, researchers at the Johns Hopkins Univ. have found another use for the popular stimulant: memory enhancer.
An Israeli nonprofit group has awarded a $1 million prize to a U.S.-based research team that is developing technology that allows paralyzed people to move things with their thoughts. BrainGate is developing a brain implant that can read brain signals and allow the paralyzed to move robotic limbs or computer cursors.
Although malaria has been eradicated in many countries, including the United States, it still infects more than 200 million people worldwide, killing nearly a million every year. In a major step toward reducing that number, a team led by MIT researchers has now developed a way to grow liver tissue that can support the liver stage of the life cycle of the two most common species of malaria.
Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.
By feeding stem cells tiny particles made of magnetized iron oxide, scientists at Emory Univ. and Georgia Tech have used magnets to attract the cells to a particular location in the body after intravenous injection. The method could become a tool for directing stem cells’ healing powers to treat conditions such as heart disease or vascular disease.
A research project in Europehas the aim of building bone implants that have been sourced from wood. The wood serves as a scaffolding that transforms to a ceramic identical to the mineral part of bone tissue: hydroxyapatite. The researchers believe the approach could appear in a clinical setting within ten years.
