Studying mice, researchers have found a way to prevent nonalcoholic fatty liver disease, the most common cause of chronic liver disease worldwide. Blocking a path that delivers dietary fructose to the liver is what prevented mice from developing the condition.
Many people with cystic fibrosis develop diabetes. The reasons for this have been largely unknown, but now researchers have identified a molecular mechanism that contributes to the raised diabetes risk.
Twenty years after the hormone leptin was found to regulate metabolism, appetite, and weight through brain cells called neurons, researchers have found that the hormone also acts on other types of cells to control appetite.
The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.
Traumatic bone injuries are often so severe that the body can’t effectively repair the damage on its own. To aid the recovery, clinicians inject patients with proteins called growth factors. The treatment is costly, requiring large amounts of growth factors. The growth factors also disperse, creating unwanted bone formation. A new developing technology could provide more efficient delivery of the bone regenerating growth factors.
Research by the University of Liverpool has found that eating prunes as part of a weight control diet can improve weight loss. Consumption of dried fruit is not readily recommended during weight loss despite evidence it enhances feelings of fullness. However, a study of 100 overweight and obese low fiber consumers tested whether eating prunes as part of a weight loss diet helped or hindered weight control over a 12-week period.
People with high levels of cynical distrust, which is defined as the belief that others are mainly motivated by selfish concerns, may be more likely to develop dementia, according to new research.
Among men treated for prostate cancer, those who received radiation therapy were more likely to develop bladder or rectal cancer, according to a new study.
Researchers identified within animal models an enzyme that links genetic pathways that control aging with the death of dopamine neurons– a clinical hallmark of Parkinson’s disease.
A multicenter team of researchers report that a commercial test designed to rule out the presence of genetic biomarkers of prostate cancer may be accurate enough to exclude the need for repeat prostate biopsies in many— if not most— men.
The risk of developing the most deadly form of skin cancer, melanoma, was more closely related to sun exposure in early life than in adulthood in young Caucasian women, according to a new study.
A team of researchers was the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, which lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine.
Almost a third of the world is now fat, and no country has been able to curb obesity rates in the last three decades, according to a new global analysis. Researchers found more than 2 billion people worldwide are now overweight or obese.
Every once in a while in the U.S., bacterial meningitis seems to crop up out of nowhere, claiming a young life. Part of the disease’s danger is the ability of the bacteria to evade the body’s immune system, but scientists are now figuring out how the pathogen hides in plain sight.
Every year, more than 1 million people in the U.S. who have suffered heart attacks or chest pain from blocked arteries have little mesh tubes called stents inserted into their blood vessels to prop them open. The procedure has saved many lives, but it still has potentially deadly downsides. Now scientists are reporting that coating stents with vitamin C could lower the implants’ risks even further.
Could a common sexually transmitted infection boost a man’s risk for prostate cancer? A new study is exploring the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.
Scientists from The University of Texas at Austin and five other institutions have discovered that the more diverse the diet of a fish, the less diverse are the microbes living in its gut. If the effect is confirmed in humans, it could mean that the combinations of foods people eat can influence the diversity of their gut microbes.
A genetic variant linked to sudden cardiac death leads to protein overproduction in heart cells, scientists report. The discovery adds to scientific understanding of the causes of sudden cardiac death and of possible ways to prevent it.
As humans, how, and why, do we think and act so differently from other species? A new study suggests that the big difference between humans and other species may lie in how we use our brains for routine tasks.
New research suggests that critically ill patients receiving steroids in a hospital’s intensive care unit (ICU) are significantly more likely to develop delirium. Results of the study suggest minimizing the use of steroids could reduce delirium in the ICU.
Technology currently used to disinfect food may help solve one of the most challenging problems in medicine today: the proliferation of bacteria resistant to antibiotics and other antimicrobial drugs.
Scientists and physicians at UC San Francisco are leading a $26 million, multi-institutional research program in which they will employ advanced technology to characterize human brain networks and better understand and treat a range of common, debilitating psychiatric disorders.
Accumulation of DNA damage can cause aggressive forms of cancer and accelerated aging, so the body’s DNA repair mechanisms are normally key to good health. However, in some diseases the DNA repair machinery can become harmful. Now, scientists have discovered some of the key proteins involved in one type of DNA repair gone awry.
Researchers have discovered how a gene commonly linked to obesity—FTO—contributes to weight gain. The study shows that variations in FTO indirectly affect the function of the primary cilium, a little-understood hair-like appendage on brain and other cells.
A new study revealed how T cells, the immune system's foot soldiers, respond to an enormous number of potential health threats and found surprising similarities in the way immune system defenders bind to disease-causing invaders.
