LSUHSC research shows drug blocks enzyme that activates bacterial and viral toxins

A paper published in the December, 2002 issue of Infection and Immunity by a research team at the Louisiana State University (LSU) Health Sciences Center in New Orleans provides clear evidence that the lethal toxins of such infectious bacteria as Pseudomonas and anthrax can be blocked by a drug developed at the LSU Health Sciences Center in New Orleans. The compound, called D6R (hexa-D-arginine), is a potent, stable, small molecule inhibitor of furin.

Bacteria produce a number of toxins whic

Muscle cell transplants repair damaged heart tissue

American Heart Association meeting report

Researchers safely transplanted 16 patients’ skeletal muscle cells into their own severely damaged hearts in the first human testing in the United States, according to a study reported today at the American Heart Association’s Scientific Sessions 2002.

“We have been able to regenerate dead heart muscle, or scar tissue, in the area of heart attack without increasing risk of death,” says lead author Nabil Dib, M.D., director o

Tissue-engineered cells transmit electrical signals in animal hearts

American Heart Association meeting report

Preliminary findings of a study in rats suggests that a person’s own cells might one day replace artificial pacemakers, researchers reported today at the American Heart Association’s Scientific Sessions 2002.

Studies conducted at Children’s Hospital Boston tested the ability of immature skeletal muscle cells to interconnect with heart cells and spread the electrical impulses that keep the heart beating properly.

Engineered blood vessels prove durable and clot resistant

American Heart Association meeting report

Researchers have built mechanically sound blood vessels out of tissue from human skin cells, according to a study reported today at the American Heart Association’s Scientific Sessions 2002. The technique involves tissue engineering, an emerging science that takes cells from the body, manipulates them in the laboratory to create functional tissue, and puts the new tissue back into the patient.

New genetic option for thwarting cancer

From ultraviolet radiation to food carcinogens, our bodies are bombarded with stuff that can make a normal cell go haywire, multiplying out of control and turning cancerous. Thanks to a set of tumor suppressor genes, however, we can defend against this daily onslaught.

Goaded into action, these genes push cells into a kind of molecular menopause, called senescence. The cells remain healthy, but they stop reproducing.

Researchers often assume that we need our tumor suppressor genes

Gene Researchers Close In On Nicotine’s "Evil Cousin"

Nicotine isn’t all bad, despite its addictive qualities and its presence in tobacco products, increasingly taboo in these health-conscious times. As a chemical compound, nicotine even has beneficial properties. It’s used around the world as a relatively cheap, environmentally friendly insecticide, repelling bugs that attack tobacco and other plants, and – contrary to popular misconceptions – it is not a carcinogen.

Take a nicotine molecule and snip off a methyl group, though, and y
