Researchers found that embryonic endothelial progenitor cells could reduce infarct size and improve regional myocardial function when delivered regionally, but not systemically. This study uses a large animal model to test the cardioprotective potential of these cells, paving the way for future human trials.
Researchers analyzed data from over 400,000 breast cancer patients to calculate probabilities of death from breast cancer vs. all other causes combined. They found that patients with ER-negative tumors and larger tumors were more likely to die from their cancer than those with ER-positive tumors and smaller tumors.
Studies found strong evidence supporting treatment of systolic hypertension in older persons with SBP of at least 160 mm Hg. Treatment guidelines recommend thiazide diuretics and long-acting calcium channel blockers as first-line therapy for SH. Despite effectiveness, poor control of SH among patients is increasing.
A study led by Mayo Clinic cardiologist Veronique Roger found that cardiac rehabilitation can improve survival rates for heart attack patients by almost 50%. However, women and elderly patients were less likely to participate in exercise programs due to factors such as lack of transportation and support networks.
Bechtel is collaborating with INEEL to test and develop critical infrastructure, including process control and SCADA systems. The partnership aims to provide scalable and secure testing capabilities for government and industry.
The new guidelines cover prevention and early diagnosis of chronic conditions, such as diabetes and heart disease, and provide evidence-based primary care interventions for people living with HIV. The guidelines also focus on caring for women and children with HIV, making them a valuable resource for a wide range of healthcare providers.
Researchers used an extremely sensitive measurement technique to study myosin VI's movement. They found that it walks in a 'hand-over-hand' mechanism, causing part of the protein to come undone. This challenges the long-held inchworm motion theory for this molecular motor.
A study found nearly 12% of salmonellosis cases in children under 5 were reptile-associated. Experts recommend keeping reptiles out of households with young children to prevent infection.
The green tea gum helps eliminate free radicals that can damage DNA and lead to cancer. It also protects healthy cells by targeting cancer cells for destruction.
Nebel was recognized for his outstanding contributions to the dairy industry through his research on electronic heat detection, leading to the development of the Heatwatch system. He is a renowned expert in reproductive efficiency and Extension specialist with over 400 published articles.
Researchers at the University of Illinois have found that sulforaphane, a compound in broccoli and other cruciferous vegetables, can block the growth of late-stage breast cancer cells by disrupting microtubules. This discovery could lead to new strategies for preventing and treating breast cancer.
The NHGRI has launched four centers to pioneer interdisciplinary research on the ethical, legal and social implications of genomic knowledge. The centers will assemble teams of experts to develop innovative approaches to addressing pressing issues in genome research.
A recent survey found that young people are more likely to smoke and have poor eating habits, with rates of obesity increasing across all ethnic groups. Despite some improvements in older adults, these unhealthy behaviors are expected to have serious consequences for future generations.
Researchers found that summer temperature is the most important variable in predicting fire extent, with increases expected in Montana, Wyoming, and New Mexico. Global warming could lead to more frequent and extensive fires, reducing old forests and habitat corridors for threatened species.
Researchers analyzed data from over 400,000 breast cancer patients to estimate the probability of death after diagnosis. The study found that breast cancer patients with ER-negative tumors were more likely to die from their cancer than those with ER-positive tumors.
