MIT researchers use high-speed atomic force microscopy to image bacteria in real-time, revealing a two-step process for AMP-induced cell death. The technique allows scientists to study living cells and gain insights into how bacteria become resistant to antimicrobial peptides.
Researchers found that a family history of early coronary artery disease increases the risk of developing obstructive CAD and plaque buildup in arteries. The study analyzed over 8,200 patients who underwent cardiac computed tomography angiography, revealing a 28% higher chance of disease development among those with a family history.
Researchers have discovered the unique genes responsible for codeine and morphine production in the opium poppy, opening doors to alternative methods of producing these painkillers. The findings could lead to more efficient and cost-effective synthesis of pharmaceuticals using microorganisms.
A new study from Henry Ford Health finds that patients with high levels of abdominal aortic calcium (plaque) are nearly 60% at risk of coronary artery disease and dying. Conversely, those with low AAC scores have a lower risk of heart disease.
A new risk score tool developed by researchers at Intermountain Medical Center has been shown to more accurately predict patients' risk for cardiac disease and death. The Intermountain Risk Score, which includes age, sex, and routine blood test results, improved doctors' ability to measure patient risk by up to 57%.
Researchers use a novel light activation technique to turn modest molecules into powerful protein destroyers, expanding the search for new therapies. The new technique, CALI, uses a 'warhead' molecule capable of inactivating nearby proteins when triggered by light.
A recent study by Duke University researchers explored the possible relationship between US stock market fluctuations and heart attack rates. The study found an inverse relationship between heart attacks and stock markets, but with limitations due to sample size and regional bias.
Scientists at Sainsbury Laboratory have discovered a new way to produce crops with broad-spectrum disease resistance using pattern recognition receptors. This breakthrough could lead to enhanced resistance in various crops, reducing yield losses and pesticide use.
A new study by Henry Ford Hospital finds regadenoson to be a safe alternative to conventional medication used in cardiac nuclear stress tests for heart transplant patients. The drug did not cause adverse side effects such as low blood pressure or heart block, and showed no signs of these conditions.
Scientists at Dana-Farber Cancer Institute have developed a laboratory technique that more closely simulates the real-world conditions in which tumor cells mingle with normal cells, improving the accuracy of anti-cancer drug screenings. This new 'cell-specific in vitro bioluminescence imaging' (CS-BLI) technique can identify compounds ...
UC Irvine researchers have sequenced the Hydra genome, discovering genes linked to Huntington's disease and beta-amyloid plaque formation in Alzheimer's. The genome sequencing advances research on regeneration, stem cells, and patterning, offering potential new treatments for various injuries and diseases.
A team of researchers has discovered that in copper-based superconductors, tiny areas of weak superconductivity can hold up at higher temperatures when surrounded by regions of strong superconductivity. This finding could lead to the creation of new materials with improved superconducting properties.
Researchers at Duke University Medical Center and the University of Oxford conducted a study to find ways to control progression to diabetes and cardiovascular disease in people at risk. Valsartan showed a moderate effect on reducing diabetes progression, but nateglinide proved ineffective at halting this progression.
Researchers found that lowering systolic blood pressure below 115 can increase cardiovascular risk for patients with diabetes and coronary artery disease. This new data challenges traditional guidelines recommending lower blood pressure levels as better.
A new high-performance anode structure based on silicon-carbon nanocomposite materials has been developed, significantly improving the performance of lithium-ion batteries. The self-assembly technique creates rigid spheres with open internal channels that allow for rapid entry of lithium ions and accommodate expansion without cracking.
Researchers used computer models to simulate silk's molecular and atomic mechanisms, revealing the arrangement of atomic bonds responsible for its strength. The study found that a critical size of beta-sheet crystals is necessary for silk to exhibit ultra-strong and ductile characteristics.
Researchers found that psychopaths have a hyper-reactive dopamine reward system, linked to violent crime, recidivism, and substance abuse. The study suggests that impulsive traits and heightened attraction to rewards overwhelm concerns about risk, contributing to problematic behaviors.
The ACCORD trial showed that targeting normal systolic blood pressure levels did not significantly reduce the risk of fatal or nonfatal cardiovascular disease events. Treating multiple lipids with combination drug therapy also did not provide additional benefits over treatment with statin alone.
