Disease progression model of pancreatic cancer developed

Building on previous work, researchers at the University of Pennsylvania School of Medicine have developed an animal model of pancreatic cancer that closely mimics disease progression in humans. From this, they hope to develop new treatments for this deadly disease.

Bacteria in plaque may increase risk for heart attacks

Researchers have found evidence that the amount of bacteria in subgingival plaques, the deep plaques in periodontal pockets and around the teeth, may contribute to an individual's risk of a heart attack, according to two studies appearing the Journal of Periodontology.

Narcotic medications can safely and effectively ease severe, chronic pain in older people

Narcotic medications can safely and effectively ease severe, chronic pain in older people with little risk that these patients will seek ever-increasing doses, University of California, San Francisco (UCSF) medical scientists have found. Younger patients, however, are likely to want to rapidly increase their medication dose, the researchers found, posing serious potential health consequences.

Nutritional composition of a mother’s breast milk may depend not just on her diet - but on her genes

“It is well known that genes control the nutrient levels in cow’s milk” said Richard B. Weinberg, M.D. “But until now, no one has considered how genes might affect human breast milk. This is the first study to demonstrate a genetic effect on human lactation.” The results were presented today at Digestive Disease Week 2005 in Chicago, Ill.

Nutrition gene key in regulating immune system

A gene that signals a yeast cell to make bread rise and mice to eat a better diet also helps selectively silence the immune system, researchers have found.

Unrestrained retina too much of a good thing

When primitive nerve cells begin forming an eye in the mouse embryo, they are programmed to build a retina. But the ability to see depends upon connecting the retina to the brain via the optic nerve. Unless these embryonic cells are given the right cue at the right time, they mistakenly form a huge eye that consists entirely of retina and lacks the optic nerve.

Chronic stress can be harmful - to your health and also to your brain

Chronic stress can be harmful - to your health and also to your brain, according to researchers at the Douglas Hospital Research Center. Their findings, published in a recent issue of Psychoneuroendocrinology, show increased stress hormones lead to memory impairment in the elderly and learning difficulties in young adults.

Jefferson researcher’s results show promise for metastatic eye melanoma

But now, by simultaneously revving up the immune system and choking off the tumor’s oxygen supply, oncologists at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia may have found a better way to battle this deadly cancer.

Smoking may have a devastating effect on gastrointestinal health

Smoking may have a devastating effect on gastrointestinal health and increase a person's risk of developing pancreatic and liver cancer, according to new research presented today at Digestive Disease Week 2005 (DDW). Furthermore, data from the Nurses' Health Study shows that meat intake and smoking play a part in significantly increasing a woman's risk of colorectal cancer.

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked

Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells known as lymphocytes would recognize the trespassers and attack them.

Pills made from the plant kudzu may help binge drinkers lose the urge

Researchers have found that drinkers seemed to lose the urge to binge-drink when they took pills made from the plant kudzu. Experts say the groundbreaking discovery may lead to a way to attack the rising binge-drinking problem which is especially prevalent among young people.

Routinely reformatting computed tomography (CT) scans to view organs from several different directions may help radiologists improve diagnosis

"You can see things in one view that you might miss in another," said Craig Barnes, M.D., section head of pediatric radiology at Wake Forest Baptist's Brenner Children's Hospital. "It costs no more as relates to scan time or radiation exposure, and we believe it provides added value in diagnosis."
