Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer’s disease in humans, according to a new study from researchers at the University of Illinois at Chicago.

What if you could see nasty microscopic air pollutants in your home?

Scientists have discovered new compounds that may explain whole grain health benefits, reports a new study led by the University of Eastern Finland. A high intake of whole grains increased the levels of betaine compounds in the body which, in turn, was associated with improved glucose metabolism, among other things. The findings shed new light on the cell level effects of a whole grain-rich diet, and can help in the development of increasingly healthy food products.

Evidence is mounting that a poor diet plays an important role in the development of age-related macular degeneration (AMD), a leading cause of blindness in the United States. A large collaboration of researchers from the European Union investigating the connection between genes and lifestyle on the development of AMD has found that people who adhered to a Mediterranean diet cut their risk of late-stage AMD by 41 percent. This research expands on previous studies and suggests that such a diet is beneficial for everyone, whether you already have the disease or are at risk of developing it. The new research is now online in Ophthalmology, the journal of the American Academy of Ophthalmology.

Fluctuations in weight, blood pressure, cholesterol and/or blood sugar levels in otherwise healthy people may be associated with a higher risk of heart attack, stroke and death from any cause compared to people with more stable readings, according to new research in the American Heart Association’s journal Circulation.

Many Americans visit chiropractors to address pain, often without informing their physicians.

Melbourne scientists have revealed a better way to identify which patients should respond to powerful ovarian cancer drugs called PARP inhibitors (PARPi), resolving an important question in ovarian cancer care about why some patients respond to the drugs, while others do not.

People can die simply because they’ve given up, life has beaten them and they feel defeat is inescapable, according to new research.

Rutgers researchers have developed a tool to help neurologists screen for obstructive sleep apnea in people with epilepsy whose seizures can be magnified by sleep disorders.
