Soluble corn fiber (SCF) may not only boost fiber intake when added to foods, but also increase the amount of beneficial bacteria present in the gut while enhancing calcium absorption, retention and bone building

Supplementing with soluble corn fiber at 2 critical times in a woman’s life – adolescence and post-menopause – can help build and retain calcium in bone, according to new research from Purdue University. “We are looking deeper in the gut to build healthy bone in girls and help older women retain strong bones during an age when they are susceptible to fractures,” said Connie Weaver, distinguished professor and head of nutrition science. “Soluble corn fiber, a prebiotic, helps the body better utilize calcium during both adolescence and post-menopause...

Patient data reveals crucial role IL-1beta in sensing streptococcal infections. Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta, a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Streptococcal infections than patients not on the drug, according to University of California San Diego School of Medicine researchers. Their study also uncovers a critical new role for IL-1beta as the body’s independent early warning system for bacterial infections.

“The more we know about each step in the body’s immune response to bacterial infections, the better equipped we are to design more personalized, targeted the...

Reseachers estimate 90% of the population have them. These strains, human herpes 6 and human herpes 7, usually do not cause severe symptoms when people acquire them. But researchers know that under certain circumstances, dormant herpes viruses in the body can unexpectedly come roaring back and cause complications not typically associated with herpes virus.”It’s common to find herpes virus in salivary glands of humans and animals,” Barcy said. “But we found herpes 7 in the nervous system of animal models, which was a surprise because that strain of herpes has not been detected in the nervous system before...

Walter and Eliza Hall Institute researchers have revealed for the first time the three-dimensional molecular ‘map’ of a protein that has been pinpointed as a driver of many types of cancers. The unprecedented view of the protein doublecortin kinase like domain 1 (DCLK1) could provide clues to how it contributes to cancer formation and progression. DCLK1 assembles scaffolds within microtubules. These rope-like structures give cells shape, enable movement and cell division, and are crucial in enabling the growth and spread of cancer cells...
