The placebo effect, study suggest pain management is possible

A Columbia professor has uncovered fresh evidence of the existence of the often-debated placebo effect. Even the professor himself, Tor D. Wager, of the Department of Psychology, was surprised by his team's findings. The study showed that the human brain processes pain differently when people believe that they have been given a pain-relieving skin cream. Wager, lead author of the study, defines "placebo" as a treatment that has no direct pharmacological effect and that may influence one's experience and physiology through one's beliefs.

Chemotherapy offers new hope for pancreatic cancer patients

Chemotherapy after surgery more than doubles survival rates for pancreatic cancer according to new research published today (18 March 2004) in the New England Journal of Medicine. Scientists from the University of Birmingham and the University of Liverpool have carried out a Europe wide study of more than 280 patients over 10 years.

Breast feeding increases choline which means more brain cells

Five years ago, University of North Carolina at Chapel Hill researchers first reported finding that the nutrient choline played a critical role in memory and brain function by positively affecting the brain’s physical development. Differences in development influenced action, the scientists and their colleagues found. In animal experiments conducted at Duke University, both young and old rats performed significantly better on memory tasks if they received enough choline before birth compared with same-age rats whose mothers were fed choline-deficient diets. The latter showed deficits in the hippocampus and septums of their brains.

Pfizer breast cancer drug looks to be best in field

A breast cancer drug made by Pfizer Inc. increased survival rates by 63 percent compared with the standard therapy tamoxifen, researchers said on Wednesday. The clinical trial strengthens the case for administering the newer drug, exemestane, as a first option. A study published last week showed that women recovering from breast cancer lowered their chance of developing another tumor by 32 percent if they switched to exemestane after two or three years of tamoxifen treatment.

New research may help prevent anthrax, bubonic plague and typhoid fever

The mechanism used by the bacteria that cause anthrax, bubonic plague and typhoid fever to avoid detection and destruction by the body’s normal immune response, leading to life-threatening bacterial infections, has been identified by researchers at the University of California, San Diego (UCSD) School of Medicine.

Research provides better understanding of lipodystrophies disorders

More than a decade of work conducted by UT Southwestern Medical Center at Dallas researchers has led to a better understanding of the underlying causes of lipodystrophies - disorders characterized by the selective loss of fat tissues, resulting in metabolic complications, such as severe diabetes and high blood cholesterol levels.

Asian poison ivy like plant may stop prostate cancer

The croton plant, long known to oriental herbalists and homeopaths as a purgative, has an oil in its seeds that shows promise for the treatment of prostate cancer – the second leading cause of cancer death in men in the United States. The active ingredient in the oil is 12-O-tetradecanoylphorbol-13-acetate, a compound generally known as TPA.

Japanese study raises concerns for childhood health issues

The number of children suffering from mental disorders and health problems such as allergies and asthma has risen sharply over the past decade in this country. The United States and European countries are also facing the increasingly serious problems of premature births and childhood obesity, in addition to allergic reactions. Many experts say the rise in health problems involving children is related to the use of chemicals in our daily lives and the impact of medical treatment provided to the children's mothers.

Research suggests the orlistat drug could be used to fight cancer and obesity

The Burnham Institute’s Jeffrey Smith, Ph.D., has discovered that orlistat, commonly prescribed as an anti-obesity drug, has a positive side-effect: it inhibits cancer growth. Dr. Smith made this discovery using an activity-based proteomics screening technique developed in his laboratory that makes it possible to identify active targets and simultaneously screen for their inhibitors.

Side Effects of Diabetes Drugs Involve Unsuspected Brain Region

A brain region involved in emotional and intellectual processes appears to also play an unsuspected role in the body’s visceral response to dangerously low blood sugar levels, according to research at Washington University School of Medicine in St Louis. Low blood sugar, called hypoglycemia, is a common and dangerous side effect of drugs that control insulin levels in people with diabetes.

New microchip manipulates DNA and protein molecules

A Johns Hopkins undergraduate has constructed a new type of microchip that can move and isolate DNA and protein molecules. He believes that by linking the chip with analysis equipment, a user could identify medical ailments, monitor a patient's health or detect viruses and other biohazards before they spread.

New optical glucose sensor could mean help for diabetics

Researchers at the University of California, Santa Cruz, have developed a novel optical glucose sensor that could be used to provide continuous monitoring of glucose levels in diabetics and hospitalized patients. Recently published studies showed that the sensor detects glucose under physiological conditions, giving a reversible fluorescent signal that changes intensity in response to changes in the concentration of glucose.
