Adoption of new guidelines recommending screening mammography every two years for women ages 50 to 74 would result in breast cancer screening that is equally effective, while saving the United States $4.3 billion a year in health care costs, according to a study led by UC San Francisco.
Children newly diagnosed with Crohn’s disease may benefit from early treatment with the biologic drugs known as anti-TNF-α agents. Researchers compared the effectiveness of early (within three months after diagnosis) treatment with anti-TNF-α inhibitors, compared with early treatment with immunomodulatory drugs, in attaining clinical remission and facilitating growth in children with Crohn's disease.
Could too much sugar be deadly? The biggest study of its kind suggests the answer is yes, at least when it comes to fatal heart problems. It doesn't take all that much extra sugar, hidden in many processed foods, to substantially raise the risk, the researchers found, and most Americans eat more than the safest amount.
In a study to be presented on Feb. 6 at 3 p.m. CST, at the Society for Maternal-Fetal Medicine’s annual meeting, The Pregnancy Meeting, in New Orleans, researchers will report that women ages 35 and older are at a decreased risk of having a child with a major congenital malformation, after excluding chromosomal abnormalities.
An experimental therapy that fed children with peanut allergies small amounts of peanut flour has helped more than 80 percent of them safely eat a handful of the previously worrisome nuts. Although experts say the results of the carefully monitored study are encouraging, they warn it isn't something that parents should try at home.
Those efforts to fight obesity in schools? Think younger. A new study finds that much of a child's "weight fate" is set by age 5, and that nearly half of kids who became obese by the eighth grade were already overweight when they started kindergarten.
The regular appearance of food poisoning in the news, including a recent event that led to the recall of more than 33,000 pounds of chicken, drives home the need for better bacterial detection long before meats and produce make it to the dinner table. On the horizon is a new approach for pathogen screening that is far faster than current commercial methods.
An international team of scientists has discovered that two of the world’s most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s.
A team of researchers has discovered a protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces. The discovery has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness, and neurological disorders.
Your best friend swears by the Paleo Diet. Your boss loves Atkins. Your sister is gluten-free, and your roommate is an acolyte of Michael Pollan. So who’s right? Maybe they all are. Researchers identified a collection of genes that allow an organism to adapt to different diets and showed that without the genes, even minor tweaks to diets can cause premature aging and death.
After 20 years, the nutrition facts label on the back of food packages is getting a makeover. Knowledge about nutrition has evolved since the early 1990s, and the Food and Drug Administration says the labels need to reflect that. Nutritionists and other health experts have their own wish list for label changes.
Scientists at UCSD developed a new genetic platform that allows efficient production of naturally occurring molecules, and have used it to produce a novel antibiotic compound. The scientists harvested a set of genes predicted to encode a natural product from ocean bacteria, then used synthetic biology technology to identify and test a new antibiotic – taromycin A – found to be effective in fighting drug-resistant MRSA.
A new study shows that humans are able to smell sickness in someone whose immune system is highly active within just a few hours of exposure to a toxin. The researchers say there is anecdotal and scientific evidence suggesting that diseases have particular smells.
Although the brain becomes smaller with age, the shrinkage seems to be fast-tracked in older adults with hearing loss, according to the results of a new study.
People with higher levels of the omega-3 fatty acids found in fish oil may also have larger brain volumes in old age equivalent to preserving one to two years of brain health, according to a new study.
Nuts are in the news: a recent study has offered evidence for a big reason our bodies are so nuts for nuts. They are apparently almost all our big brains needed to survive— thus almost all we ate— from 1.4 to 2.4 million years ago.
Researchers are set to decipher the genomes of a main bacterial cause of food poisoning, which results in over 21,000 hospital admissions and 100 deaths each year.
A new study conducted by sleep and systems biology researchers has found that the daily rhythms of many genes are disrupted when sleep times shift.
Scientists have discovered that two genes linked to hereditary Parkinson’s disease are involved in the early-stage quality control of mitochondria.
A collaboration of surgeons successfully transplanted kidneys into 50 recipients using an innovative robot-assisted procedure in which the organ is cooled with sterile ice during the operation.
The probability of blindness due to the serious eye disease glaucoma has decreased by nearly half since 1980, according to a new study. The researchers speculate that advances in diagnosis and therapy are likely causes for the decrease.
People who enjoy life maintain better physical function in their daily activities and keep up faster walking speeds as they age, compared with people who enjoy life less, according to a new study.
A large global team of reproduction experts has found a way to even the score for older women seeking pregnancy using a process called preimplantation genetic diagnosis (PGD).
A thickening of the brain cortex associated with regular meditation or other spiritual or religious practice could be the reason those activities guard against depression– particularly in people who are predisposed to the disease, according to new research.
Cancer cells have something that every prisoner longs for— a master key that allows them to escape. A study describes how a protein that promotes tumor growth also enables cancer cells to use this key and metastasize.
