A new study found that a rigorous environmental cleaning intervention can reduce the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) in hospital intensive care units (ICUs). The multi-modal cleaning protocol reduced MRSA acquisition by 61%, while VRE acquisition decreased by...
Researchers found that proper irrigation management with reuse water can maintain favorable salt balances and plant response. The study's results suggest embracing reuse water as a viable alternative for golf course irrigation.
Researchers at University at Buffalo found that single-walled carbon nanotubes do not experience electromigration and thermomigration like metals, producing significantly less heat. This property makes carbon nanotubes ideal for future electronic devices, including electric cars and sophisticated naval systems.
A new report from the University of Southampton finds that long-term daily drinking is the biggest risk factor for serious liver disease. The study suggests that regular drinking patterns can be discernible at an early age and recommends several alcohol-free days a week as a healthier pattern.
Local rectal cancer excision is effective for stages Tis and T1 cancers, with prevention of recurrence and postoperative follow-up increasing efficacy. Administering salvage therapy also improves outcomes.
Researchers are developing new classes of anti-androgen therapies, including MDV3100, abiraterone, and OGX-427, to treat castrate-resistant prostate cancer (CRPC). Angiogenesis inhibitors like bevacizumab target vascular endothelial growth factor (VEGF) to slow tumor growth and metastasis.
The Stent 4 Life campaign targets reperfusion therapy with percutaneous coronary interventions (PCI) to reduce STEMI patient mortality. It encourages the application of PCI above 600 per million population in Europe, aiming to address most STEMI patients' needs.
Scientists at Queen's University have detected giant twisting waves in the lower atmosphere of the Sun, known as Alfvén waves. These waves transport energy into the Corona or outer layer, carrying heat and explaining why it reaches temperatures of over a million degrees.
Research reveals cathepsin B's role in hepatocyte apoptosis and liver injury in fulminant hepatic failure. Inhibition of cathepsin B attenuates apoptosis and liver damage.
Researchers found that only four rest areas and six weigh stations showed promise for wind power generation in Illinois. The study determined grid parity was not achievable due to high electricity costs, but rebates and subsidies made some sites viable.
Recent research suggests that monoclonal antibodies can stimulate both innate and adaptive immune responses, leading to more powerful control of cancer. This breakthrough could lead to the development of new treatments that alter antibodies to induce long-lasting immunity.
Researchers from the University of Sheffield and Queen's University Belfast have made a groundbreaking discovery about the Sun's corona. They found evidence for the existence of Alfvén waves, which transport energy to heat the Sun's outer atmosphere, reaching temperatures of over a million degrees.
Researchers have identified a novel syndrome associated with chronic cannabis abuse, characterized by severe vomiting sickness. The syndrome was first recognized in Australia and is believed to be caused by years of marijuana use, leading to increased cases worldwide.
