Nutrient "floodgate" protects against inflammatory immune response

After every meal, the body must prevent the immune system from launching an all-out fight against food.

Renewal of Echinacea and St John's Wort research

A five-year-old research center dedicated to understanding and improving Echinacea and Hypericum perforatum (St. John's wort) has received $4.4 million in continuation funding from the National Institutes of Health. The renewal is for three years.

Treating ticks with antibiotics inhibits their reproduction

Bacteria that may provide ticks with essential nutrients they can't get from their meals of blood could be a key to controlling ticks and the diseases they carry, a new study published in the PLoS ONE shows.

Men and women at risk for alcohol dependence are more likely to choose a mate who also is at risk

Alcoholism is more common among partners of alcoholics than among partners of non-alcoholics, but it isn't as common as it might be. The researchers found that in some cases, one spouse's excesses with alcohol actually could help protect the other from alcohol dependence.

Single gene is responsible for most cool temperature sensation

The discovery, reported in the May 3 issue of the journal Neuron, might one day lead to the development of drugs that induce cold sensation as an analgesic, or block it to prevent certain forms of chronic pain associated with cold sensation.

Prenatal toxicity linked to immune dysfunctions in later life

A Cornell researcher and his wife have conducted the first comprehensive review of later-life diseases that develop in people who were exposed to environmental toxins or drugs either in the womb or as infants.

Machine preservation may promote more organ sharing

Preserving the kidneys of deceased older donors on a pump, as opposed to the conventional method of storing and transporting organs in a cooler, may lower hospital costs, improve initial organ function, and promote greater use and more sharing of organs, according to new research by Wake Forest University Baptist Medical Center.

Scientists discover molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years

By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1.

Backup brain region compensates for stroke

Researchers have pinpointed in humans how a "backup" brain region springs into action to compensate for disruption of a primary functional area, as happens during stroke.

Gene malfunctions cause schizophrenia, depression symptoms in mice

Researchers have demonstrated for the first time that malfunction of a gene that had been associated with schizophrenia and depression does indeed cause symptoms of those disorders.

Women from all ethnic backgrounds are more successful at passing UK medical exams than their male counterparts

Women from all ethnic backgrounds are more successful at passing UK medical exams than their male counterparts, according to research published in the open access journal BMC Medicine.

New way to target and potentially treat tumors

Research teams at Yale University and the University of Rhode Island have demonstrated a new way to target and potentially treat tumors using a short piece of protein that acts like a nanosyringe to deliver tags or therapy to cells, according to a report in the Proceedings of the National Academy of Sciences.

Scientists discover way to distinguish pancreatic cancer from non-cancerous tissue

The research examined pancreatic cancer cells for tiny molecules called microRNA (miRNA). It shows that relative levels of certain miRNAs can distinguish pancreatic cancer from nearby noncancerous tissue and from inflamed pancreatic tissue.

No link between autism and celiac disease

Contrary to previous studies, autistic children are no more likely than other children to have celiac disease, according to new research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28, May 5, 2007.

New tool refines heart risk prediction

For about 10 years, the Framingham risk score has been used to estimate a person's chances of having a heart attack based on just six bits of information -- age, sex, total cholesterol, HDL cholesterol, smoking status, and systolic blood pressure.

Psychotherapy extends the lives of cancer patients

Previously-published research has given credence to the notion that psychotherapy extends the lives of people with cancer.

Statin drugs also may help reduce risk of heart failure

Statin drugs, known primarily for their ability to lower cholesterol, also may reduce the overactive sympathetic nervous system response that contributes to the worsening of heart failure and increases the risk of sudden cardiac death, two University of Missouri-Columbia researchers have found. Heart failure is the leading cause of morbidity and mortality in the United States.

Variants of two genes involved in the inflammatory system linked to cognitive decline after heart surgery

Duke University Medical Center researchers believe their findings could help physicians identify patients at risk of suffering mental decline after heart surgery and raises the possibility that these patients could be treated with drugs that are known to dampen the inflammatory response.

Biomarker discovery bodes well for better cancer diagnostics

While new findings from Ohio State University scientists suggest a genetic marker that could help distinguish between chronic pancreatitis and pancreatic cancer and gauge who will do well with cancer treatment, a pharmacologist at the Kimmel Cancer Center at Jefferson in Philadelphia sees the discovery as much more.

Distrust played a role in residents' response to Hurricane Katrina warnings and advice

While investigating the impact of Hurricane Katrina on New Orleans evacuees, a group of UCLA researchers stumbled across something they had not been looking for the deep level of distrust the largely minority victims felt toward public health authorities.
