U.S. health regulators are trying to help doctors spot counterfeit and unapproved drugs by raising awareness of illegal operations that peddle bogus drugs to health professionals.
Six months into the biggest-ever Ebola outbreak, scientists say they know more about how the...
If you're overweight, you may be at greater risk for stress-related diseases like type 2...
Although the heart beats out a very familiar "lub-dub" pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a "constant" heart rate— and that variability, doctors have found, is a good thing.
Dry roasted peanuts are more likely to trigger an allergic reaction than raw peanuts, suggests a study involving mice. The researchers say that specific chemical changes caused by the high temperatures of the dry roasting process are recognized by the body's immune system, “priming” the body to set off an allergic immune response the next time it sees any peanuts.
Researchers have developed a chip capable of simulating a tumor's "microenvironment" and plan to use the new system to test the effectiveness of nanoparticles and drugs that target cancer. The new system, called a tumor-microenvironment-on-chip device, will allow researchers to study the complex environment surrounding tumors and the barriers that prevent the targeted delivery of therapeutic agents.
Doctors treating a Spanish priest who was repatriated from West Africa today after being diagnosed with the Ebola virus say there are no samples of experimental drug ZMapp available in the world right now, and they are considering alternative treatments.
More than 700 infants may have been exposed to tuberculosis at an El Paso hospital over the past year by an employee recently diagnosed with the illness, health officials have said.
Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense.
Chronic stress can lead to behavioral problems. A team of researchers has discovered an important synaptic mechanism: the activation of a cleaving enzyme, leading to these problems.
Shoppers in Sierra Leone rushed to stock up on food Thursday ahead of a three-day nationwide shutdown, during which the country's 6 million people will be confined to their homes while volunteers search house-to-house for Ebola victims in hiding and hand out soap in a desperate bid to slow the accelerating outbreak.
Eating too much meat often makes the headlines, whether the risk of doing so is equated to smoking or cited as the cause of rising diabetes rates. Though some of these articles have already been labeled as sensational journalism, a new study has shown that people who eat more protein— whether from plant or animal sources— tend to have a lower risk of hypertension, also known as high blood pressure.
A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer. A new study suggests that adding nutraceuticals to chemotherapy cycles may improve the effectiveness of conventional drugs, particularly in hard to treat cancers.
Think the flu's only a big threat to kids and seniors? Influenza hospitalized a surprisingly high number of young and middle-aged adults last winter— and this time around, the government wants more of them vaccinated.
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity.
Using artificial sweeteners may set the stage for diabetes in some people by hampering the way their bodies handle sugar, suggests a preliminary study done mostly in mice. The researchers and outside experts said more study is needed, while industry groups called the research limited and said other evidence shows sweeteners are safe and useful for weight control.
The idea of the Ebola virus becoming airborne is not far-fetched as its ability to enter cells that line the trachea and lungs has been shown under controlled laboratory conditions, a virus expert says.
Transmission of bacterial infections, including MRSA and MSSA, could be curbed by coating hospital surfaces with microscopic bumps that mimic the scaly surface of shark skin.
Up to 80 percent of sexually active women are infected by the human papillomavirus at some point in their lives and infection with specific "high risk" strains of HPV has an established link to cervical cancer. Current screening by smear test is invasive and time-consuming. Urine samples may be a viable alternative.
Chikungunya, a mosquito-borne virus similar to dengue, is spreading rapidly in the Western Hemisphere. Although there is little risk of it becoming a major threat in the U.S., health officials are still warning residents to exercise caution when outdoors as there have been confirmed cases in the U.S., mostly due to traveling citizens. Check out the infographic for more info on the relatively unspoken-about virus.
Waist circumference is a simple measure of total and intra-abdominal body fat. The prevalence of abdominal obesity and average waist circumference increased among U.S. adults from 1999 to 2012.
A new stereotactic radiosurgery system provides the same or a higher level of accuracy in targeting cancer tumors, and offers greater comfort to patients and the ability to treat multiple tumors at once, when compared to other radiation therapy stereotactic systems.
The American strategy on Ebola is two-pronged: step up desperately needed aid to West Africa and, in an unusual step, train U.S. doctors and nurses for volunteer duty in the outbreak zone. Amid criticism that the world still is not acting fast enough against the surging Ebola epidemic, Pres. Obama travels today to the CDC to discuss the outbreak with health officials who've been there.
A peek inside the brains of more than 750 children and teens has revealed a key difference in brain architecture between those with attention deficit hyperactivity disorder and those without. Kids and teens with ADHD lag behind others of the same age in how quickly their brains form connections within— and between— key brain networks.
During cancer development, tumor cells decorate their surfaces with sugar compounds called glycans that are different from those found on normal, healthy cells. New research has found that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter’s response to the tumor– for good and bad.
New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in a patient's blood— often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
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.
