A clinical trial at UT Southwestern Medical Center aims to determine whether adding the hormone leptin to standard insulin therapy might help rein in the tumultuous blood-sugar levels of people with type 1 (insulin-dependent) diabetes. This is the first type 1 diabetes treatment trial involving leptin, which is naturally produced by fat cells and involved in body-weight regulation. For this study, UT Southwestern researchers will be using metreleptin, a slightly modified form of the hormone...

A set of proteins found in blood serum shows promise as a sensitive and accurate way to diagnose Alzheimer's disease, researchers at UT Southwestern Medical Center have found as part of a statewide study. An analysis of the proteins, plus a clinical exam, proved 94 percent accurate in detecting suspected Alzheimer's and 84 percent accurate in ruling it out in people without the disease, the researchers said. "This research uses a novel technology that makes it possible to analyze several...

Young adults who abuse amphetamines may be at greater risk of suffering a tear in the main artery leading from the heart, UT Southwestern Medical Center researchers have found. In the study, published in the August issue of American Heart Journal, researchers examined medical records from nearly 31 million people between 18 and 49 years old hospitalized from 1995 to 2007 and found that amphetamine abuse was associated with a threefold increase in the odds of aortic dissection. "Aortic...

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug. "We found that the amount of blood flow in areas of the brain known to be involved in the rewarding effects of cocaine and craving was different in cocaine addicts, compared with healthy subjects," said Dr. Bryon Adinoff, professor of psychiatry at UT Southwestern and lead...

Researchers at UT Southwestern Medical Center have uncovered a key step in the creation of new red blood cells in an animal study. They found that a tiny fragment of ribonucleic acid (RNA), a chemical cousin of DNA, prompts stem cells to mature into red blood cells. The researchers also created an artificial RNA inhibitor to block this process. Such interventions, if fruitful in humans, might be useful against some cancers and other diseases, such as polycythemia vera, in which the body...

Researchers at UT Southwestern Medical Center have uncovered the biological rationale for why large doses of corticosteroids given repeatedly over several weeks may help individuals with lupus, a chronic inflammatory disease that affects more than 1 million people in the U.S. Unlike the anabolic steroids athletes sometimes use illegally to bulk up muscle, corticosteroids are routinely used to treat inflammation in lupus patients. The drugs, however, can cause undesirable side effects...
