Vanderbilt investigators have found that childhood vaccinations do not harm children with a certain type of inborn errors of metabolism (IEM) called urea cycle disorders. “Our study is one of the first to take a group that everyone would agree is going to be medically fragile and look at vaccines in this sub-group,” said Thomas […]
High levels of a protein associated with chronic, low-grade inflammation in the brain correlate with aspects of memory decline in otherwise cognitively normal older adults, according to a study led by scientists at the University of California, San Francisco. The study is being reported in a poster session at the American Academy of Neurology annual […]
Stress not only sends the human immune system into overdrive – it can also wreak havoc on the trillions of bacteria that work and thrive inside our digestive system. New research suggests that this may be important because those bacteria play a significant role in triggering the innate immune system to stay slightly active, and […]
Certain cases of major depression are associated with premature aging of immune cells, which may make people more susceptible to other serious illness, according to findings from a new UCSF-led study. The findings indicate that accelerated cell aging does not occur in all depressed individuals, but is dependent upon how long someone is depressed, particularly […]
There has been substantial mystery surrounding the origins of Chronic Fatigue Syndrome (CFS) – a condition affecting as many as four million Americans and marked by symptoms that include a sense of weariness that sleep does not improve and difficulty with memory and concentration. A study published in 2009 suggested that a retrovirus known as […]
Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells. Re-activation and growth of HSV1 infections contribute […]
Stress can change the balance of bacteria that naturally live in the gut, according to research published this month in the journal Brain, Behavior, and Immunity. Exposure to stress led to changes in composition, diversity and number of gut microorganisms, according to scientists from The Ohio State University. The bacterial communities in the intestine became […]
A retrovirus that inserted itself into the human genome thousands of years ago may be responsible for some cases of the neurodegenerative disease amyotrophic lateral sclerosis (ALS), also known as Lou Gherig’s disease. The finding, made by Johns Hopkins scientists, may eventually give researchers a new way to attack this universally fatal condition.
