OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

Research conducted in monkeys at the Oregon National Primate Research Center, Oregon Health & Science University, suggests high doses of vitamin C may have potential to counteract some negative impacts of smoking in unborn babies. The research may benefit thousands of babies born to mothers who continue to smoke throughout pregnancy despite physician warnings. The research is published in the...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

Oregon Health & Science University researchers have identified some of the key factors that prevent the repair of brain damage caused by multiple sclerosis (MS), complications of premature birth, and other diseases and conditions. The findings offer important clues about why the nervous system fails to repair itself and suggest ways that at least some forms of brain damage could be reversed....

OHSU discovery sheds light into how stem cells become brain cells

Researchers at the Oregon National Primate Research Center at Oregon Health & Science University (OHSU) have discovered one key gene that appears to control how stem cells become various kinds of brain cells. The finding has significant implications for the study of Parkinson's disease, brain and spinal cord injury, and other conditions or diseases that might be combated by replacing lost or...

OHSU study says stem cell 'fusion' occurs in tumors

An Oregon Health & Science University study is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue. . Scientists in the OHSU School of Medicine found that transplanted cells derived from adult bone marrow can fuse with intestinal stem cells of both normal and diseased tissue comprising the cellular lining of...

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells

Researchers at the Vaccine and Gene Therapy Institute (VGTI) at Oregon Health & Science University have demonstrated how certain white blood cells literally eat virus-infected cells while fighting disease at the microscopic level. The research not only helps provide a clearer understanding of the body's immune system, it also offers hope of a new method for gauging vaccine effectiveness. The...

OHSU lab finds meth receptor that could lead to therapy

A recently discovered signaling system in the brain has just been shown to be turned on by methamphetamine, an Oregon Health & Science University study found. . .. Working in the recently opened Program in Chemical Biology in the OHSU School of Medicine's Department of Physiology and Pharmacology, scientists demonstrated the new target of meth, and its close relative amphetamine, is a G prote...

OHSU surgeon implants donated tissue allografts

Over the years, orthopedic surgeon Dennis Crawford, M.D., Ph.D., of Oregon Health & Science University found it difficult to obtain tissue for transplant to treat some of his patients suffering with severe joint disorders. . .. Until recently, however,...
