By studying the role of this gene, the team discovered its connection to inflammation and found that neutralizing a specific protein can reverse symptoms in affected animals.
Scientists found a connection between triplet repeat genes and brain disorders like Huntington's disease, where proteins errantly stick to an enzyme crucial for energy production in brain cells. The discovery offers a potential treatment option by blocking protein interactions.
Researchers found nitric oxide plays a central role in hemoglobin's function, regulating gas exchange and blood pressure. The discovery could lead to developing the first effective blood substitute and treating diseases associated with oxygen deficiency.
Petit mal or absence seizures affect 100,000 US children and account for one-fifth of childhood epilepsies. The new findings may lead to more effective treatments, which can have a profound effect on a child's development.
Researchers at Duke University and the Institute for Cancer Research have located a second breast cancer susceptibility gene, BRCA2. This gene is expected to account for most of the remaining 50% of inherited breast cancers not caused by BRCA1. Women who inherit BRCA2 are at an 85% risk of developing breast cancer.
A Duke University study of 934 patients found that those treated with bypass surgery or angioplasty had better long-term survival rates compared to medication alone. Patients who underwent revascularization showed a significant increase in three-year survival rates, with bypass surgery resulting in the greatest percentage of survivors.
A new study suggests that the ratio of calcium to magnesium in ostracod shells provides a reliable method for reconstructing ancient water temperatures. The technique, described in the journal Science, shows strong signals in temperature change between glacial and interglacial periods.
A Duke University Medical Center study shows that alcohol severely disrupts a biochemical process associated with memory formation in young animals. The findings provide compelling scientific evidence to support prohibition of underage drinking, as the brain is more plastic and susceptible during late childhood or early adolescence.
Researchers at Duke University have made significant advancements in rebuilding the human immune system using thymus transplants. The breakthroughs offer new hope for patients with severe immunodeficiencies and potentially life-threatening illnesses.
The striatum, a portion of the brain previously thought to control movement, is shown to keep track of short intervals from seconds to minutes. This finding has implications for understanding timing in learning and memory, as well as Parkinson's disease.
A new outcomes scorecard system developed by cardiologists at Duke University aims to improve the accuracy of comparing hospitals' performance in common cardiology procedures. The system analyzed data from almost 8,000 coronary disease patients and showed a wide variation in death rates among hospitals.
Researchers are exploring two protocols to tackle AIDS: Protocol 1 focuses on reconstituting immune systems through thymus tissue transplants and boosting T-cells. Protocol 2 involves high-dose chemotherapy, radiation, and blood stem cell transplantation to treat cancer and restore immunity in patients with double jeopardy.
Researchers at Duke University found that harmless doses of DEET, permethrin, and pyridostigmine bromide become highly toxic when used together. This combination may explain the wide range of symptoms reported by an estimated 30,000 Gulf War veterans.
The new technology uses parallel computing to analyze reflected sound waves, creating three-dimensional images quickly enough for clinicians to view a whole human heart as it beats. The system also enables doctors to electronically dissect and display selected slices of medical interest on a computer screen.
Duke University Medical Center surgeons have developed a safe and effective treatment for Zenker's diverticulum, a disabling condition that traps food in the throat. The new endoscopic technique removes the pouch with minimal complications, offering hope to elderly patients with this condition.
A study published in the American Heart Association scientific meeting found that cardiologist care significantly reduces heart attack mortality. The research, led by Dr. James Jollis, analyzed Medicare claims data from 220,535 patients diagnosed with a heart attack in 1992 and discovered that patients cared for by cardiologists had a ...
Research suggests that physically fit women experience lower blood pressure during stressful days at work, compared to unfit women. This buffering effect reduces the risk of heart disease.
Researchers at Duke University Medical Center report a genetically modified version of hemoglobin as a safe blood substitute during surgery. The product, rHb 1.1, is designed to carry oxygen efficiently and eliminate disease transmission and immunosuppression, potentially reducing medical costs for patients and hospitals.
Researchers have protected growing brain cells from atrophying by treating them with a protein called NT-4, which fosters brain cell growth. This discovery could offer new treatment options for diseases involving gain or loss of brain cell connections, such as mental retardation and neurodegenerative diseases.
